ABSTRACT

Wavelet analysis is a technique possessing mathematical properties and it has been used by the scientific research community for its power to analyse rapidly changing transient signals used to represent data or functions - the wavelets used in the analysis are, however, functions that break the data down into different scales or resolutions. Wavelets possess the competence to handle spikes and discontinuities than traditional Fourier analysis and make the noisy data to de-noisy. Though traditional applications of wavelets have focused on image compression and analysis, wave propagation but they are also being used to analyse time series, biological processes, spectroscopic data of chemical compounds, seismic signals for earthquake prediction, atmospheric data for weather prediction, computer graphics, medical image technology, detection of aircraft and submarines, non-parametric regression, density estimation, and long memory wavelet models. Indeed, wavelets permit complex information such as music, speech, images and patterns to be decomposed into elementary forms at different positions and scales and subsequently being reconstructed with high precision. Signal transmission is based on the transmission of a series of numbers, indeed, the series representation of a function is important in all types of signal transmission.Wavelet transform of function is the improved version of Fourier transform. Fourier transform is a powerful tool for analysing the components of a stationary signal. But the Fourier transform fails to analyse the non-stationary signal where as a wavelet transform allows the components of a non-stationary signal to be analysed.

1. INTRODUCTION

The concept of product management in market research is all about tradeoffs. Whether the objective is to increase market share, profit margin or revenue, every product manager makes trade-offs—quality vs. cost, time to market vs. breadth of features, richness of the offering vs. ease of use, etc. So, how does anybody know what the market wants? What market segments exist? What those segments prefer? What will they pay? or what trade-offs to make? The answer is to get the market to make the trade-offs. The conjoint analysis is the tool to measure the trade-off i.e. to understand customer preferences, values and choices. Conjoint analysis is used for many marketing decisions, including new product development process, selecting among alternative product designs, targeting, and pricing. It is also used to predict their choices for future products and services. Conjoint Analysis assumes that a product can be “broken down” into its component attributes. For example, a car has attributes such as colour, price, size, miles-per-gallon, and model style. Using Conjoint Analysis, the value that individuals place on any product is equivalent to the sum of the utility they derive from all the attributes making up a product. Further, it assumes that the preference for a product and the likelihood to purchase it are in proportion to the utility an individual gains from the product. It is generally inappropriate for products which are evaluated by consumers on the basis of their “image”, such as beer or cigarettes, rather than on the basis of their constituent attributes. It is so widely used in market research that helps to understand the market’s preferences including product development, competitive positioning, pricing, product line analysis, segmentation and resource allocation.That gives the better insight to the market revenue, share, profit which in turn helps to provide the better market intelligence. The present chapter deals with the genesis, usefulness and analysis procedure of conjoint analysis in different software with example.

Growth is a complex biological process that must be evaluated carefully if a profitable combination of growth and efficiency is to be realized. Knowledge relating to birth weight, mature weight, maturity rate and the point of infection of the growth curve in various breeds and crosses is very useful in selecting breed combinations that can produce the most efficient growth pattern. The effect of cow size on economy of production has been a discussing subject among cattlemen and animal scientists. Growth models are used to predict rates and change in the shape of the organism. They can be applied to determine the food requirements so as to get a desired growth. The estimated parameters of growth function can evaluate various growth characteristics of animal like rate of maturing, rate of gain, mature size and related characters.

1. INTRODUCTION

Agriculture plays a crucial role in addressing the needs of a growing global population, and is inextricably linked to poverty eradication, especially in developing countries. Sustainable agriculture and rural development are essential to the implementation of an integrated approach to increasing food production and enhancing food security and food safety in an environmentally sustainable way. Attaining food security has been our major concern since independence. Appropriate policy measures in agriculture made it possible to achieve food security as well as required national confidence to meet the growing food demands, despite a growing population. The increased agricultural production has been achieved largely through an increase in the yield of grain per hectare, rather than from an increased cultivated area. The increase in production has been the result of widespread cultivation of new high-yielding varieties coupled with a package of agricultural inputs that permit the genetic expression of their high yield potential. India is now even in a position to export agricultural commodities, fish products, milk products and earns a lot of foreign exchange. The present share of the agricultural sector in total exports is 15 to 17 percent. However, the export of many agricultural commodities show a high degree of fluctuations, caused by time lags between production decisions and delivery to the market. For the Government, unforeseen variations in export can complicate budgetary planning and increase risks for attainment of debt targets. For exporters, price volatility increases cash flow variability and reduces collateral value in the market. There is a need for an aggressive export growth-oriented policy to raise the share of agricultural sector in total exports to 25%. This should come through diversification of agriculture. In our country, the exports have been allowed only after domestic requirements are met, which is the major cause of fluctuations in exports from year to year. Modelling and forecasting such fluctuating data of commodities is crucial for the sake of Government as well as for the exporters.

INTRODUCTION

Agricultural systems and the environment in which it operates have become increasingly complex which encompass both agricultural production and marketing systems. Both of them are rich in complexity and diversity (Spedding, 1975) and to understand the complexity and structure of such systems and their functions require the use of mathematical modelling frameworks that represent their key features. Disciplines that are required to develop and solve such models include: biology, computer programming, statistics, mathematics, economics, and social science. Models are being developed to investigate specific issues such as weed infestation, soil health, nitrogen cycling, the effects of climate change, climate variability, and to assist developing countries to improve their production at their farm gate. During the first half of 20th Century, most agricultural products were produced by means of labour and the majority of the produce was used for own consumption. However, as time progressed labour was substituted for machines, production became more market-oriented and consequently the practice of farming also transformed from “a way of living” to business enterprises run on business principles.

INTRODUCTION

The role for economic theory is no longer simply to explain how the existing system works, but also to explore how the economic system can be changed to become more adaptive and resilient in the face of the challenges of the 21st century, and how it can be more directly designed to support human well-being, in the present and the future. Simultaneous changes are needed, in both the actual economy and also in theoretical approaches of economics. The economic theory that was accepted as standard in the non-communist world during the second half of the twentieth century erects serious impediments to meeting the challenges of the twenty-first century. In order to redirect economics to be more useful, and more truly reflect the world we now face, a good starting point is to go back to the goals that are embedded in economic thinking. Here it is useful to make the distinction between intermediate and final goals. Final goals are ends that are worth achieving in themselves, while intermediate goals are pursued because they are expected to contribute to the final goals. As final goals for any economy are ‘well-being and equity in the present’ and second is ‘productive capital for the future’. Productive capital needed to maintain well-being also necessarily includes natural resources, as well as human health and education, and cohesive social systems. Increasing production and consumption are important intermediate goals for humankind in some times and places. Other obviously critical intermediate goals include climate mitigation, and promoting resilience and adaptation within both human society and ecological systems. Responding to global inequity as well as global climate change requires coordinated public policy to fundamentally redirect existing economic systems. In addition to a much greater emphasis on equity, economic theory that is appropriate to the needs of the twenty-first century will need to be more concerned with the meta-externalities of the economic system. The business sphere is currently creating meta-externalities of culture and politics that place great burdens on the core sphere, and that tie the hands of governments. This does not necessarily imply that the for-profit sphere is “bad” and the others “good”—rather that institutional changes must be made to bring the purposes and functions of all three spheres into better harmony. To address such a complex issues, economic theories and models that developed in the past should embedded with new advent in computational technologies. In venturing a vision of technological possibilities rather than simply projecting linear or exponential changes in performance, it is crucial to think not only of how technical improvements lead to the substitution of a new generation of tools for existing ones, but also of how entirely new uses, and indeed new needs, might emerge.

In today’s technology driven 21^st century, software has become an integral part of our day to day work. Starting from checking day’s schedule in tablet after waking up in the morning till setting up alarm before going to bed at night, we are using numerous software applications in a day without even realizing the efforts spent to make those applications work perfectly every time we use it. If we look deeply, each software application in computer or in any electronic/computer controlled device go through multiple rigorous cycles of testing to ensure that it is working as intended after it was built by developers and before it was launched in market for public use. In software industry, this process is termed as software quality assurance (QA) or software testing which is being considered as one of the most flourishing verticals of IT software services sectors in 21^st century.

Software testing is one of the most important phases of software development life cycle and it consumes anything between 10% to 45% of project budget depending on the type of the software and methodology followed in the development and testing life cycle. There are different types testing e.g. unit testing, integration testing, system testing, user acceptance testing, alpha, beta testing which are exercised during the testing phase and QA team needs to provide the sign off before any product is released and implemented in production or in consumer market. With the ever increasing complexity of today’s software products along with the competitive market due to easy availability of multiple product options/vendors, the importance and awareness of software quality assurance has increased over years. Consequently, various software testing methodologies have been evolved in last two decades in order to perform testing in more structured and controlled manner. In addition, there is a continuous urge for improving the operational efficiency of the testing process in the organizations in order to produce better quality software at less cost.

1. INTRODUCTION

Until the 1990s, the phrase Corporate Governance (CG) was relatively unknown but since then it has gained a huge importance when the corporate sector was surrounded with problems of unethical practicesand flagrant violations of rules and regulations in a number of countries. CG has received increased attention as multiple cases of risk of corporate failures both for public and private sectors. Multiple corporate failures worldwide, such as those of Maxwell, Enron, Global crossing, and Sunbeam forced the regulatory authorities to set up codes and standards on CG.The Indian market has also faced a number of scams since early nineties.Harshad Mehta Stock Scam in 1992 is one of the corporate frauds in the country which finally resulted in setting up of Kumar Mangalam Birla Committee in 1999. Based on their recommendations in 2000, Clause 49 on CG was inserted in the listing agreement of every stock exchange in India. The purpose was to promote and raise standards of CG of listed companies. CG has now become most common phrase in the business world of 21^st century. It is important for financial health of the corporations and relationshipwith the public at large; may it be an individual or community especially after the collapse of Satyam Software Services Ltd. in 2008.It has been made mandatory for the Indian companies to comply with CG norms, to give reports and disclosures as per the listing agreement and various provisions of the Companies Act in their annual reports. The importance ofCG in the 21^st century keeps on increasing as the economy is growing.

ABSTRACT

This paper broadly deals with salient applications of Information Technology in various areas related to Agriculture Research, Government’s digital initiatives, Indian Council of Agriculture Research IT initiatives in agriculture research as step, towards reaching agriculture knowledge and technology to small holders (Resource-Poor-Farmers). The present paper identifies new emerging areas of usage of computer application in Horticulture research and development.

INTRODUCTION

The horticultural sector is facing the challenges of dwindling land resources, increasing biotic and abiotic stresses, indications of factor productivity decline, threatened loss of bio-diversity, new IPR regime etc, (Adiguru and Mruthyunaja, 2004). Further, Indian agriculture has come under significant adjustment pressure from market liberalization and globalization. Farmers need reliable and timely information about best practices of production, processing, marketing, input and output prices, financial markets and risk-covering institutions. Existing public extension system has become outdated and ineffective in spite of the fact that it has been a catalyst in successfully heralding the Green Revolution in the country. This is partly due to an inadequate use of new means of information dissemination (Adhiguru et al., 2003). The public extension system follows a top-down approach and has become less interactive, more time-consuming and costly and fails to meet the expectations of those involved in the agricultural production and other involved in the value chain. Therefore, a new extension system re-oriented to meet the information needs of the farmers should be put in place across the country by using ICT.

ABSTRACT

Intellectual property rights (IPR) have, in recent years, emerged as perhaps the most important aspect of legal system as far as protection of inventions is concerned. Intellectual property rights have been created to ensure protection against unfair trade practices. The protection of intellectual property rights (IPR) could be a means to acknowledge a creator for something new or it could be means to recover the financial investments of a financer. IPR ensures that the knowledge, innovation and capital involved in the development of a product/ technology are compensated with highest rewards, insufficient protection of IP will lead to fewer rewards and even some of the inventions will be driven to extinction. As a result the innovators may conveniently relocate to regions where they can protect the IP they develop, the latter will result in intellectual loss to a particular country. Knowledge management on the other hand, emphasizes the challenge behind effective management of innovation systems by providing protection to databases, learning tools and sharing process that innovators have developed over a period of time. Effective Knowledge management provides platform for sharing of technologies through licensing and cross-licensing agreements between different countries. The chapter deals with the fundamentals of intellectual property, its types, the applications of different categories of intellectual property in the area of science and technology including biotechnology, literature and arts, and the commercial value of intellectual property assets. Moreover, protecting traditional knowledge through the intellectual property rights and identification, documentation transmission revitalization and promotion of cultural heritage by traditional knowledge has been discussed.

1. INTRODUCTION

Science and Technology are vital for developing low-input and high-output agriculture and pharmaceutical. India needs frugal use of natural resources and diversification of agricultural activities. Transgenic technologies are highly misunderstood. Genetically modified crops are a result of them. In fact genetic modification of crops for human use is going on since their domestication. By introduction of Bt cotton in 2002, yields have doubled. American bollworm can no longer threaten Indian cotton crops. Insects can develop resistance to Bt gene or some virus attacking the crop needs more research. RNA-mediated gene suppression may aid the development of patent strategies that will support the next generation of genetically modified crops and enhance scope of patenting. Many fancy Organic farming, which will need 40 percent more agricultural land for present number of people on earth although it is ever increasing. Biotechnology has revolutionized agriculture, healthcare, industrial processing, environmental sustainability and is also a revenue generator. India is poised for a tremendous growth in BT sector. NanoBT has now entered into furthering the useful research on faster pace. It has scientific and technical pool of human resources, rich biodiversity, large agricultural and market base for new BT products and world recognition as a producer of low cost, high quality bulk drugs and formulations. Issues surrounding Intellectual Property Rights and BT inventions are varied but interrelated. Basic research has to be transferred to applied field and the resultant is to be commercialized. In some countries, plant varieties are protected by sui generis system. Post genome research has added fuel to the fire; new innovative fields, like ‘Bioinformatics’ with plenty of biology information and new processing methods have emerged. BT uses four tools of IPR, viz. Patents, Trademarks, Trade secrets and Copyright. At present, its contribution to the World’s patenting activity is less than three percent. As such there is a necessity to amend the IP laws to give better protection to R&D, and better enforcement of IP, technology transfer and licensing arrangements. Biotech industry in India is flourishing more in pharmaceuticals, particularly in healthcare. There is an urgent need for harmonization of administration and centralization of the patenting process in accordance with WIPO diktats.

INTRODUCTION

Intellectual Property Right (IPR) is described as a generic legal term for patents, copyrights, and trademarks, making the feasibility for legal rights to protect ideas, the expression of ideas, and the inventors and creators of such ideas (Brown, 2003). Two types of rights, first, associated with patents and second, associated with copyrights are included into the current IPR regimes. The social purpose behind the IPR is to reward the originator of an invention. Intellectual property serves as a strong foundation of the modern information economy since it promotes software, life sciences, and computer industries, and has becomes a part of most of the products we consume today (Gallini and Scotchmer, 2002).

INTRODUCTION

Mass production was the hallmark for improvement of productivity in early 20^th century. Subsequently the productivity development was driven by the use of information technology and related concepts like Entrepreise resource planning (ERP), Customer relationship Management (CRM), Business Process Reingineering, TQM etc. These technologies and concepts were instrumental in collection, codification, analysis, decision making and execution of decision which translated to better coordination and profitability. The ability to harness synergy out of the information systems, coordinated team and goal orientation helped in executing strategies with sharpness, proactively identifying customer need, responding to social context and competitive scenario with alacrity. As it stands now, with internet and multimedia technologies it is faster to form organization, reach out to the stakeholders. Technology mediation has improved the productivity and quality of economic activities. It has still lot more options to come in the 21^st century.

Sovereign state performances from different parts of the world have been going through a different set of social and performance context. Over last couple of decades multiple social issues have surfaced. Issues like “rich and poor divide”, “increase of least developed countries (LDCs)”, have forced a thinking about the efficacy and efficiency of governance processes. The social and economic context in multiple countries gave rise to the Millenium Development Goals (MDG) of the UN. Governments in most of the countries have short life span than before, and are now elected with lower margins. The recent Jasmine revolution has eliminated entrenched dictators, almost without bloodshed vastly due to the use of technology like, social-e-media platforms. Regional aspirations have become strong, vociferous and demanding. Splintering of USSR, Sudan, Unification of Germany, Iraq, overthrowing of monarchy in Nepal and closer home in India, there is clamour for more states. In a multi-party democracy, few national parties have got splintered into or have given rise to multiple regional political parties to represent the local aspirations. Governments are now grappling with economic crisis. Democracy as the form of the government, ironically, has not been able to live upto the expectations. On different facet, recently the issues like wikieleaks and exposure of snooping of different governments on its own citizens, have indicated the lack of trust of people.

Abstract

Ethnobotany as an academic discipline surfaced in the 19^th century. Traditional medicine is used globally and is of rapidly growing economic importance. In developing countries, traditional medicine is often the only accessible and affordable treatment available. The chapter deals with importance of plants in the life of people, value of collecting the plant samples and adding knowledge to plants based on their economic potential and issues related to ethnopharmacology.

Keywords: Ethobotany, Ethnopharmacology, Drug discovery, Research ethics.

Abstract

The Himalaya is one of the youngest and the richest mountain ecosystems encompassed with a variety of species of both flora and fauna. Varying in climatic conditions coupled with altitudinal gradients and unique topography leads to the formation of different types of forests, which varies from tropical to the temperate and alpine to no timber line zone and snow-clad meadows. The present study aimed to investigate the potential of medicinal plants growing in valleys and mountains of district Doda to cure various ailments of the local inhabitants including animal health care. A total of 113 species belonging to 104 genera and 55 families of angiosperms, gymnosperms and cryptogams (lycophytes and ferns) were recorded and reviewed from published documents used for treatment of different diseases in the regions. Out of the total 113 species, 17 species were of trees, 14 species were shrubs, 78 types of herbaceous plants and 4 species of climbers. Asteraceae, Lamiaceae, Rosaceae, Ranunculaceae, Polygonaceae, Solanaceae, Apiaceae, Pinaceae, Fabaceae and Berberidaceae were recorded as the dominant families of the study area. The data were collected while interacting with local people as they possess rich traditional knowledge regarding the use of different herbal plants and medicine.

Abstract

Sikkim is part of the eastern Himalayan hotspot. Rich biological diversity of the region is owing to its wide range of topography, varied climatic condition and high annual precipitation, inhabited by three major ethnic communities, the Lepchas, Bhutias and Nepalese. With its unique ethno-cultural diversity and equally rich Phyto-diversity, the region holds an immense ethno-botanical knowledge and potential. The collection of food, fodder, fuel wood, timber, herbs for folk medicine from wild is an integral and deep-rooted cultural component and for sustaining socio-economic condition of the people. Medicinal plants of this region have potential for value addition as well as domestication. The folk medicine practices of three ethnic groups are different, but in general there are strong beliefs system in relation of folk medicine with supernatural forces and deities; local people consider its mountain peaks, forest, lakes as sacred hence it helps in sustainable management of its natural resources traditionally. Developments activities, urbanization, overexploitation of important plants and not giving due importance to the traditional knowledge in the past decades leads to the potential depletion in wild and that bring concern for their conservation. A proper strategic plan is needed for conservation of these valuable resources and promoting the indigenous traditional knowledge for sustainable development. Conservation-linked with people participation has been initiated in Sikkim through Sikkim State biodiversity board (SSBB), with its biodiversity management committees (BMCs), and local activist and stakeholders. The research institution of the region and researcher from outside has contributed immensely in documentations of the ethno-botanical knowledge and phyto-diversity of this region. This chapter reviews the current status of traditional ethno-botanical knowledge system of Sikkim state and highlights the current scenario of biological diversity; conservation practices, threats and challenges.

Abstract

Asteraceae, one of the largest families of flowering plants, is of worldwide distribution and inhabits almost every environment except Antarctica. The family exhibits various life forms and is known to harbour a wide variety of phytochemicals. The study aimed at systematically documenting the precious ethnobotanical knowledge (ethnomedicinal, ethnotoxic and wild edible plants) of Asteraceae in district Udhampur. A total of 42 infomants between the age group 21-90 years were interviewed and 28 plant species of Asteraceae belonging to 26 genera were observed to be of ethnobotanical significance in district Udhampur. All the taxa were growing in wild and majority of them were herbs. The ethnomedicinal formulations were prepared in the form of paste, decoction, powder, etc which were found to be effective against plethora of ailments. The ethnotoxic plants were observed to exert their adverse effects by causing different ailments or diseases. The present study may serve as a base line data for further research and will go a long way in the treatment of major and minor ailments, protecting people from being poisoned by substances that may have cured them and also serving as food source.

Abstract

Plants have been the source of food and medicine since time immemorial. Tribal people have been using several plants and their parts as source of alternative food that is conventionally not consumed by urban population. However recently, due to increasing population and reducing agriculture land, such alternative foods are gaining attention. Such alternative foods often also have medicinal value and are consumed by tribals for ameliorating certain disorders. Due to rising costs of modern medicine and associated side effects, general public perception is positive for alternative medicines and traditional therapies. Yams are an example of such alternative medicinal foods and are the focus of this chapter. Here we describe the ethnobotanical and nutraceutical potential of yams. We have discussed, in detail, some of the species that are consumed in various regions of India. During the compilation of this data, it was noticed that detailed molecular information is not available for most species, while for some species almost no molecular data exists. Further, many species have not been properly evaluated through modern natural product chemistry and pharmacological screening methods to validate the claims made in ethnobotanical surveys. These and other lacunas in knowledge pertaining to yams have also been pointed out towards the end of the chapter.

Abstract

Crocus sativus L. commonly called as saffron is a Persian plant belonging to the Iridaceae family and is cultivated for more than 4000 years. It grows exclusively in India, the Balkans and the eastern Mediterranean region. Saffron is traditionally used for, as a food supplement and its pharmacological properties such as antihypertensive, anticonvulsant, anxiolytic aphrodisiac, antioxidant, antidepressant etc. It comprises of the dried stigma which comprises of 150 different types of metabolites, of which some are responsible for the color, flavor and aroma of the Saffron. Saffron is a plant with great significance as an adaptogen and seems to be promising as a nutraceutical in barring several diseases. The current chapter explores the Ethnobiology, historical background, chemical constituents, ethnopharmacological properties, uses and toxicity of Saffron.

Abstract

Wild medicinal plants have been major source of therapeutic agents for alleviation or cure of human diseases since time immemorial. These are extensively utilized throughout the world in two distinct areas of health management i.e., modern medicine and or folk medicine. Some of the important medicinal plants grown and cultivated in India for medicine, phytochemicals, nutraceuticals, cosmetics and others are Abelmoschus moschatus, Aristolochia bracteata, Cassia alexandrina, Caralluma fimbriata, Gymnema sylvestre, Withania somnifera and other species. They have become important sectors of trade and commerce. However, in India, about 90% collection of medicinal plants is form wild source and since 70% of collections involve destructive harvesting, many plants have become endangered or vulnerable or threatened. The increasing demands of the pharmaceutical industry have created problem of supply and one of the major difficulties being experienced by the industry is that of obtaining sufficient quantities of medicinal plants for the manufacture of genuine medicine.

Abstract

Mentheae, one of the largest tribes of subfamily Nepetoideae of family Lamiaceae is represented by five genera (Mentha, Nepeta, Origanum, Salvia and Thymus) in Jammu and Udhampur districts (Jammu division). Frequent surveys made of these districts to generate ethnobotanical data revealed the existence of Mentha arvensis L., M. longifolia (L.) L., M. piperita L., M. spicata L., Nepeta cataria L., Origanum vulgare L., Salvia splendens Sellow ex Schult and Thymus serpyllum L. While the enlisted Mentha species are represented more or less equally in the two districts, N. cataria, O. vulgare, S. splendens and T. serpyllum are mainly adapted to temperate regions of Udhampur. The frequent interactions with the locals indicated that except M. spicata whose leaves are used for seasoning dishes or preparing refreshing drinks and those of O. vulgare which find utility in making herbal tea, others are largely used for therapeutic purposes. Amongst these species, maximum use value was noted for M. longifolia (0.81) followed by that for M. arvensis (0.69). So far as agreement among the informants regarding the usage of a species for curing a particular disease is concerned, it came out to be maximum for both M. longifolia and M. arvensis for treatment of respiratory (Fic=0.93) and gastrointestinal problems (Fic=0.93). In our study, most of the informants have predisposition towards using M. longifolia for treating respiratory disorders particularly cough and cold. For this species, fidelity level was found to be maximum equal to 33.33%. This indicates that M. longifolia carries great potential for using in new herbal formulations. Finding of lesser use value for O. vulgare (0.21) and T. serpyllum (0.30), reportedly having many medicinal important components, is a matter of concern. The probable reasons underlying quite less usage of these taxa have also been discussed in this communication along with the future prospects of cultivating these.

Abstract

Medicinal plants growing around us are the biggest gift to mankind from the nature. They grow abundantly and over centuries, humans have learned how to utilise plants for the treatment of illness. The great Himalayan belt is home to many endemic medicinal plant species. These plants are the rich source of traditional medicines and form a basis for livelihood of rural and indigenous populations. The present study is aimed to investigate the medicinal wealth of Bani valley that lies in Kathua district, (J&K) which is a part of Western Himalaya. Due to varying climatic conditions, terrains and forest types, the valley is home to various endangered and endemic medicinal plant species. A total 231 plant species belonging to 69 families ranging from angiosperms, gymnosperms and cryptogams (lycophytes and ferns) were documented by frequent field surveys and reviewed by published literatures and floras. Out of 231 plant species, herb species were 142, shrub species were 43 and tree species were 46. Asteraceae was recorded as dominant family followed by Fabaceae, Lamiaceae, Rosaceae, Polygonaceae, Ranunculaceae, Poaceae, Solanaceae, Acanthaceae and Urticaceae. Ethnobotanical data used for various ailments and diseases were obtained from local tribes.

Abstract

Genus Chlorophytum is represented by approximately 300 species of rhizomatous plants, distributed predominantly in tropical and sub tropical forests of the world. Most of these are medicinally important. Chlorophytum borivilianum Santapau & R.R. Fern among these is highly valued because of high saponin content mainly concentrated in its tuberous roots. These steroidal saponins are important bioactive components responsible for aphrodisiac attributes of this species in addition to several other benefits. Present communication reviews the data available on medicinal properties and phytochemical constitution of the species.

Abstract

Mythology is a unique subject of religious or cultural traditions. Plants play a vital role in the practice of these traditions. The use of plants may be an approach towards their conservation by demonstrating their magico-religious importance or their efficiency in keeping away some infectious microbes. Reason may be any, but all such herbs needs scientific interventions with respect to their usage. In this manuscript 69 such plant species are enumerated which are used for magico-religious purposes. Maximum species were recorded from dicots and seeds have shown maximum percentage among the plant parts to be used for the purpose. The knowledge about the magico-religious usage among the inhabitants is communicated through oral, literature or practice. The quantitative indices like Cultural Significance Index and Factor Informant Consensus have been calculated for the collected data from 92 informants in the region. The calculated ethnobotanical quantitative indices indicate Capsicum annuum and Santalum album are the culturally more significant plants and there is a strong homogeneity in the practices among the people of different districts.

Abstract

India with plethora of flora and fauna is a rich repository of cultural and ethnic diversity. Bestowed with varied biogeographically distributed ecosystems and biodiversity hotspots, the country has always been the torch bearer as far as ethnobotanical knowledge is concerned. Jammu and Kashmir in the North-Western part of India has a rich biological and cultural diversity. Owing to the distinct geographical location and varied climatic conditions, district Poonch represents a rich repository of biodiversity including the wealth of medicinal plants. This study aimed at documenting and examining the use of plants in various medicinal herbal preparations. A total of 223 plant species belonging to 77 families and 173 genera were documented to be used as ethnomedicine by people residing in the study area. The portion of plant parts used were leaves (28.14%), followed by root (16.33%), fruit (11.55%), whole plant (10.3%), stem (09.79%), flower (7.53%), seed (5.27% each), rhizome (4.77%), tuber (3.76%), bulb (1%) and bark and latex (0.75% each). These parts are utilized as herbal remedies for curing 109 human ailments such as abscess, acidity, asthma, back pain, body pain, boils, cancer, cholera, cold, cough, dandruff, erectile dysfunction, eye pain, fever, gastroenteritis, haemorrhoid, high blood pressure, menstrual disorders, sexual disorders, stomach pain, diabetes, diarrhoea, dysentery and weakness. The dominant disease was fever (52), followed by abdominal pain (30), cough (29), headache (22), constipation (20), diabetes (18), wounds (17), weakness (16) and others. There is need for proper documentation and an attempt has been made to highlight high value medicinal plants so that proper strategies could be made for their conservation.

Abstract

Pomegranate, Punica granatum L., is an ancient fruit tree native to the Middle East. All plant parts are rich source of the various secondary metabolites that accounts for its antioxidant and health-promoting activity. A strong genetic control on anthocyanin production is responsible for variability in the color of peel and arils of pomegranate. Characterization, cloning and expression of the genes related with anthocyanin and tannin production provides routes for engineering of these complex pathways. Recent studies on pomegranate genome sequencing have elucidated several biochemical pathways and candidate genes that could assist to increase production of potent bioactive compounds in near future. This will further facilitate our understanding to some exclusive biological processes that plays a significant role in pomegranate breeding.

Abstract

Jasrota Wildlife Sanctuary (JWS) in Jammu and Kashmir (J&K) Union Territory is floristically less explored. Between 2018 and 2019, field surveys and exploration tours were undertaken to obtain information from local people residing around JWS through open interviews, semi-structured questionnaires and group discussion. Total 113 informants were contacted and data collected by means of ‘snowball method’. A total of 138 species of 60 medicinal plant families were documented subjected to preliminary investigation, which includes 47.10% herbs, 28.26% trees, 19.57% shrubs, 4.35% lianas, and 0.72% parasites. Most dominant families were Fabaceae (11 gen. and 12 spp.), Lamiaceae (6 gen. and 8 spp.), Asteraceae (8 gen. and 8 spp.), Moraceae (2 gen. and 6 spp.), Caesalpinaceae (4 gen. and 6 spp.), Rosaceae (5 gen. and 5 spp.), Euphorbiaceae (4 gen. and 5 spp.), Solanaceae (4 gen. and 4 spp.) and Malvaceae (4 gen. and 4 spp.). Some of the common high valued medicinal plants were Ajuga integrifolia, Aloe barbadensis, Asparagus adscendens, Boerhavia diffusa, Cassia fistula, Lantana camara, Murraya koenigii, Ocimum tenuiflorum, Tinospora cordifolia, Zingiber officinale and several other plants. Traditionally lesser used plants were Abrus precatorius, Acacia catechu, Commelinabenghalensis Cyperus rotundus, Silene vulgaris, Robinia pseudoacacia, Urtica dioica and Ziziphus mauritiana. These medicinal plants are used in treatment of obesity, anti-helminthic, liver infection, diabetes, intestinal infections, rheumatism, tumours, stomachache, insomnia, nerve troubles, skin infection, aphrodisiac, memory related disorders, dermatological problems and asthma. Species with high frequency index should be analyzed for pharmacological research and for discovering of new medicines. It has been observed that lots of medicinal plants grows in this protected area and this sanctuary need proper conservation and management planning.

Abstract

Genus Artemisia L. (Asteraceae) has a long history of use in herbal medicine, owing to the presence of rich bioactive phytochemical diversity of it constituent species. Himalaya is hub of several species and species under this genus have been traditionally used in different ways for curing ailments by inhabitants of the areas where their populations sprawl. Few species such as A. annua and A. maritima are cultivated for their use in medicine. In addition, the species of the genus have found wide usage in matters connected to digestive system especially for treatment of worms and for preparation of herbal teas. Artemisnin, a potent source of anti-malarial drug extracted from some species, is most valuable bioactive phytochemical of this genus. Other important chemical constituents include santonin and scoparine. Reported studies suggest that the bioactive constituents present in this genus shows several biological activities such as antimicrobial, anti-inflammatory, anticancerous and other allied ones activities. Expansion of range and acclimatization in new habitats is exemplary in this genus. Present work reports the ways of range expansion, economic importance, conservation strategies and future prospects of this genus.

Abstract

Toxic plants are a grave threat to existence and bodily functions of humans and animals resulting in death or sickness through accident, unawareness or bad intention resulting in huge economic loss. They have always been part of our daily life and some of them are so prevalent that we do not even doubt their poisonous nature. The study aimed at systematically documenting the precious traditional knowledge regarding the ethnotoxic plants of district Udhampur. Ethnotoxic data was collected by interviewing 125 infomants between the age group 24-95 years. A total of 89 plant species belonging to 69 genera and 43 families were observed to be toxic to either humans or animals or both. Majority of the taxa were growing in wild. Leaves were observed to be the most toxic plant parts. Frequently encountered toxic plant families include Fabaceae, Solanaceae, Asteraceae, Euphorbiaceae, Apocynaceae and Ranunculaceae. The route /mode of entry of toxic chemicals was mainly observed to be ingestion. A total of 62 ailments/ conditions/diseases were reported to be caused in humans or animals or both by the ingestion, contact or inhalation of toxic plants in the present study. These include nausea, vomiting, headache, diarrhoea, hematochezia, abdominal spasms, anorexia, dysuria, deep yellow or no urine, bloat, etc. The present study may serve as a base line data for further research and will go a long way in safeguarding people from being poisoned by stuff that may have healed them.

Abstract

Herbal healthcare forms the most favored system for curing various ailments of the people residing in remote areas of Himalayan region. Gujjar and Bakerwal tribes inhabit the hilly areas of Pir Panjal region of J&K along with their livestock and rely on the surrounding bio-wealth for their healthcare needs. But, proper documentation of traditional knowledge about the medicinal plants has been poorly attempted in this part of J&K. In order to develop a data base of plants being used by Gujjar and Bakerwal tribes of district Poonch, present attempt has been made. The present compilation recorded one hundred forty five plant species belonging to 133 genera and 76 families which are used by the tribal people to cure various ailments like rheumatism, diarrhea, dysentery, skin and gastric problems, wound healing etc. These medicinal plants comprise of 25 trees, 27 shrubs, 82 herbs and 11 climbers. Of the total, 44 species are native to Himalayan region and 101 are non native.

Abstract

Malaria is a widespread disease in the developing world, known to mankind since primeval times. It exists over hundreds countries of the world. Malaria is caused by the Plasmodium parasite and cause disease in over 30 crores people annually and kills approximately 10 lakhs people worldwide. Plasmodium protozoan species which causes malaria can be differentiated into four species viz. P. malariae, P. falciparum, P. vivax, and P. ovale. Among all these four species P. falciparum parasite has got resistance to all common antimalarial drugs available in the market; therefore it is a devastating strain of Plasmodium causing of serious disease and death. The rising resistance of existing remedy based on quinoline is a key provider to the re-emergence of malaria as a main public health difficulty and its widen to fresh locations and populations. Therefore, In this compilation, an effort is made to compile clinical features of malaria, life cycle of Plasmodium sp., different classes of antimalarial drugs and their mechanism of actions and recent advances in target based discovery and recent development in artemisinin research especially different kinds of artemisinin derivatives and new structural classes of antimalarial agents. We have also reviewed new leads discovered as antimalarial from natural products where we have possible to see new lead in near future.

The Indian arid zone is characterized by high temperature and low and variable precipitation which limit the scope for high crops productivity. However, these conditions greatly favour the development of high quality in a number of fruits such as date palm, ber, aonla, bael, pomegranate, kinnow, lasoda and in vegetables cucurbits, legumes and solanaceous crops, spices, medicinal and aromatic plants. The existing low productivity could be increased by following improved technologies and inputs. It is now realized that there is a limited scope for quantum jump in fruit and vegetable production in the traditional production areas. The amelioration of the extreme conditions is also considered vital for life support to the inhabitants of this area. The recent awareness regarding the potential of these ecologically fragile lands for production of quality produce has not only opened up scope for providing sustainability for the people of this region, but also for bringing in new areas to increase horticultural production. The area expansion and yield potential of arid horticultural crops has increased many folds because of development of new varieties and advancement in production techniques in arid region.

The hot arid regions of India are spread over 32 million hectares in the states of Rajasthan (61%), Gujarat (20%), Punjab (5%), Haryana (4%), Karnataka (3%) and Andhra Pradesh (7%). The arid regions of western Rajasthan experience an annual rain fall between 100-500 mm with a coefficient of variations varying from 40-70 per cent. Low and erratic rainfall coupled with extreme temperature results in complete or partial crop failure, considerably affects the agricultural economy of the region. High wind velocity causes wind erosion and shifting of sand dunes covers the fertile agricultural land and canals (Rao and Singh,1998). The rise in temperature begins from March onward and attains its peak in May as high as 46°C. The transpiration is low during winters but during summer in months (May & June), it reaches up to 16 mm per day. The annual estimated potential evapotranspiration values ranges from 1600 mm in eastern part and 1800 mm in western part of the region.

In the arid regions of Rajasthan, Haryana, Punjab and eastern part of arid Gujarat the soils have developed from alluvial and aeolian parent materials. In context to the type of soils light brown sandy soils with dune dominance is 30.6 per cent and associated others 34 per cent area, light brown soils 1.7 per cent, Grey brown soils 13.6 per cent hard pan in 5.9 per cent and seirozems in 1.7 per cent area (Dhir, 1977). Kolarker et al. (1989) reported that in 12 district of Rajasthan sandy soils dominated in 14.3 million ha. These soils are poor in fertility very low organic carbon (0.03-0.1%), light in texture called desert soils (north western) in the order of aridisols. It has undulated topography with the dominance of sand dunes inter-dunal plains. About 80 per cent area falls under rain fed cropping and moth bean, cluster bean, pearl millet, and sesame are the main crops grown during kharif season after the onset of monsoon. Under the vagaries of monsoon and recurrent drought the rain fed cropping becomes a gamble, which creates severe food and fodder scarcity in the region.

Rajasthan has geographical area of 3.42 lakh sq. km has attained the status of being the largest state of India. The state represents 10.4% land surface area with 5.5% population of India, 66% is dependent on agricultural for their livelihood. The state is divided into 33, districts, which are further subdivided into 338 Tehsils and 295 Panchayat Samitis. The total cultivable area is around 220.00 lakh ha. The average rainfall of the State is 575 mm, out of which about 532 mm precipitation occurs in the rainy season i.e. June to September. The average rainfall of eastern Rajasthan is about 704 mm and that of western Rajasthan is about 310 mm which reflects a vast variation. Rivers in Rajasthan are non-perennial except for Chambal and Mahi rivers. The State is presently divided into 33 administrative districts and has 10 agro-climatic zones. Agriculture in Rajasthan is primarily rain fed covering country’s 13.27 per cent of available land. Groundwater is getting depleted as well as polluted. In general, every third year is a drought year. Despite these, the State has made significant achievements since independence and has attained self-sufficiency in food- grains. Rajasthan is located in the north-western part of the subcontinent. It is bounded on the west and north-west by Pakistan, on the north and north-east by the states of Haryana, Punjab, and Uttar Pradesh, on the east; in the south- east by the states of Uttar Pradesh and Madhya Pradesh, and on the south- west by the state of Gujarat. The Tropic of Cancer passes through its southern tip in the Banswara district. In the west, Rajasthan is relatively dry and infertile: this area includes some of the Thar Desert, also known as the Great Indian Desert. In the south-western part of the state, land is wetter, hilly, and more fertile.

Vegetables are of short duration, have higher productivity and give more return per unit area, besides giving nutritious food to human being and can be fitted in different farming systems. They also play a major role in balancing human diet, thereby helping in alleviating hunger, poverty and malnutrition. Because of the public awareness for the significance of vegetable consumption, the demand of vegetables in the global market has increased immensely. Thus, vegetable farming is becoming profitable venture globally, opening avenues of self employment and revenue generation (Anon., 2009). At global level, India holds second position, next only to China in vegetables production with a share of about 14%. The present annual vegetables production of country is about 175 million tons from an area about 10.3 million ha with a productivity of 17.1 t/ha. India grows largest number of vegetables in the world, as having a spectrum of wide range of agro-climatic situations, ranging from dry temperate to humid tropics between the altitudes from sea level to snow line.

The Indian hot arid region is one of the most important arid ecosystems of the world in terms of biodiversity it possesses. This arid region spreads over 31.7 mha, occupies major part of north western India including Rajasthan, Gujarat, Punjab and Haryana, which together contribute 73% of arid region. High temperature, wind velocity, low humidity, low and erratic rainfall and high potential evapotranspiration are important characteristics of this region which narrowed down the choice for vegetables, besides permit their low productivity.

Vegetables are short duration crops and provide more returns per unit area and time besides, they play a major role in balancing human diet, thus, helping in alleviating hunger and malnutrition (Annon., 2009). In the previous few years, India has attained quantum jump in vegetable production and present estimated vegetable production is around 162.9 mt in an area of about 9.4 mha (NHB, 2014), and holds second position at global level. But this level of vegetable production is insufficient to meet the recommended daily intake (~300 g per capita per day) for a huge population of the country. This is mainly due to lower average productivity (17.5 t/ha) of the nation. There are several crop diminishing factors such as soil borne- and foliar- diseases, insect-pests and nematodes as biotic factors, and soil or water salinity, alkalinity, metal toxicity and heat and moisture stress as abiotic factors, which greatly affect vegetable crops yield in almost all growing areas, especially in fragile arid and semi arid regions.

India is a natural reservoir of the several fruit species. The several less known fruit species, which have the potential for commercial exploitation, are yet to be utilized to their potential. An attention to the less known fruit would play a significant role in increasing the income, providing employment opportunities, uplifting of the poor, small and marginal farmers and the development of value added products. These fruits are well known for their medicinal and nutritive value. There is a great need to develop and popularize not only for their domestic market but also for their export. Some of the less known fruits are described here with respect to their cultivation technology.

With the culmination of green revolution, the yield in agriculture is almost static with the use of even great deal of inputs and resources with appearing decadence in nature. The agriculture, if continuous on with same trend, will no longer productive and sustainable. Heterogenity being vested with best survival and sustenance, attempt is underway towards crop diversification deploying remunerative crops and techniques so as to keep pace with rising demand of mankind. Added to this, dwindling land : man ratio (0.13 ha during 1990s), harvesting more return from a unit area of land, disguised unemployment, improper availability of fruits and vegetables (40 g and 120 g respectively as against 120 g and 280 g for fruits and vegetables, respectively), generating employment (143 man-days/ha in cereals, 860 man-days/ha in fruit production and 1000-2500 man-days/ha in cultural intensive fruit crops), are major concerns for high density planting (HDP). It is a holistic production system which helps in promoting and preserving dynamic agro-ecosystem. HDP is also an aid to biodiversity, biological cycles and organic farming. As an alternative to raise production and productivity especially to compete global trade, HDP is worth adoption.

India has witnessed tremendous increase in the production of horticultural crops especially fruits since independence. Due to specialized scientific interventions and application of latest research tools, the country is now among the top fruit producing countries of the world ranking second next only to China. However, the productivity has still remained low as against area under the fruit cultivation. Several neglecting issues related to the production technology have remained unattended so far. The old and senile orchards are now reverting towards a declining trend of production because of plant age factor, non-compatible varieties and poor canopy management (Baba et al., 2011).

In the recent past declining productivity of old and dense orchards existing in abundance has become a matter of serious concern for the orchardists, traders as well as scientists. In India 30-35 per cent area under fruit crops is occupied by old, dense and diseased orchards. For overcoming the problem of unproductive and uneconomic orchards existing in abundance, large scale uprooting and replacement with new plantations (rehabilitation) will be a long term and expensive strategy. Therefore research efforts were initiated to standardize a technology for restoring the production potential of existing plantations by a technique called Rejuvenation. The term ‘Rejuvenation’ means renewal or making new or young again. As applied to the orchard tree it would mean restoring the productive capacity of the fruit trees. The meaning of ‘Rejuvenation’ according to Chamber’s dictionary is ‘to recover youth character or to grow again’. Obviously, this would apply to those plants which have attained a stage where they are no more profitable from the grower’s point of view.

The arid zone of India covers about 12% of the country’s geographical area and occupies over 31.7 mha of hot desert and about 7 m ha under cold desert. The arid regions of Rajasthan, Gujarat, Punjab and Haryana together constitute the Great Indian Desert known as Thar Desert that accounts for 89.6% of hot arid regions of India. In Gujarat, 6.22 m ha area is under arid zone which constitute 19.6% of the arid area of country (Fig 1). In Gujarat, eight districts fall under arid zone, namely, Kachchh (100% of district area), Jamnagar (80%), Surendranagar (29%), Junagadh (20%), Banaskantha (18%), Mehsana (7%), Ahmedabad (6%) and Rajkot 6%).

Since time immemorial India has been leader in respect to spice, area, production and consumption. India is known as ‘Land of spices. Out of 109 spices listed by the ISO, India produce as many as 63 owing to its varied agroclimatic regions. Almost all the state and union territory of the country grow one or the other spices. Spices are the sources of livelihood and employment for large number of people in the country. Seed spices are annual herbs, whose dried seeds or fruit are used as spices. Spices are the nature’s gift to mankind and since antiquity, spices have been considered indispensable in the culinary art, as they are used to flavour foods and beverages The important seed spices are coriander, cumin, fennel, fenugreek. ajwain, dill,, celery, anise, nigella and caraway. The other seed spices s are poppy seed, rai, yellow mustard, white mustard, parsley and sesame. In India, Rajasthan and Gujarat has emerged as “Seed spice bowl” and together contributes more than 80 percent of total seed spices.

Burgeoning population exerts pressure on limited precious natural resources for enhancing production of food, fodder and fuel. In order to meet out increasing demand for food, fruit, vegetables, oilseeds, fodder and timber wood for burgeoning population, it is necessary to utilize each unit of natural rsesource very efficiently. The productivity of the precious natural resources is to be enhanced per unit time per unit area by agronomic ally managing stresses soil and land ecosystem to harvest more benefit. The cropping system as well as intercropping system practised by using different trees, fruits, vegetables, crops are the very efficient enterprises for realising higher productivity of natural resources available with in specified ecosystem.

The arid zone eco-system of Rajasthan is very fragile and is prone to serious imbalance even with the slightest disturbance due to mismanagement of resources. Among the eastern margin of the mean annual rainfall is 500 mm, while in the western most part it is 100 mm. The rainfall is monsoon driven. It comes between June and September (in 9-21 short spells). Large coefficient of variation (40-60%) and erratic distribution during the monsoon are characteristics features of the rainfall, leading often to prolong drought and failure of rainfed crops (More and Samadia, 2007). Temperature as low as 4.4° C, and as high as 50° C has been recorded in Western Rajasthan. Farming system and cropping system approach for sustainable use of farm resources and reduced risks have been successfully demonstrated in perennial horticulture. There is great pressure of livestock on available feed and fodder, as land available for fodder production has been decreasing. The requirement of dry and green fodder by 2025 would be 1170 mt and 650 mt while supply is expected around 411.3 mt and 488 mt deficit will be 64.87 % green fodder and 24.92 % dry fodder (Table 1).

Henna or Mehandi (Lawsonia inermis L.) a perennial shrub belongs to family Lythraceae. It is commonly cultivated as a commercial dye crop possess natural dyeing properties and are used for hair dyeing and for staining of palm, feet and other body parts since times immemorial. The plant finds their importance due to presence of orange red dye in its leaves and essential oil in its flower. Oil extracted from leaves and flower called ‘Otto of henna’ which is utilized as perfume (Jaimini et al., 2005). It can grow well in harsh climate of arid and semiarid regions. In India, over 90 percent of the henna production comes from Sojat region of Pali district of Rajasthan and Sojat is only center for its processing and trading in India. In India it occupies about 40,000 ha area out of which 35,000 ha alone is in Pali district (Sojat and adjoining tehsils).

Geographical distribution

It occurs naturally in North Africa mainly in countries of Algeria, Cyprus, Egypt, Eritrea, Ethiopia, Indonesia, Iraq, Iran, Jordan, Kenya, Kuwait, Lebanon, Libya, Malaysia, Morocco, Oman, Philippines, Qatar, Saudi Arabia, Syrian Arab Republic, Tanzania, Tunisia, Turkey, Sahara and Yemen. It is naturally occurring in many of these countries along the water courses and semi-arid regions where it can with stand dryness as well as drought. It has been introduced into countries like Australia, Benin, Burkina Faso, Cameroon, Central Africa, Chad, Congo, China, Gabon, Gambia, Ghana, Guinea, India, Liberia, Mali, Mauritania, Niger, Nigeria, Pakistan, Senegal, Sierra Leone, Spain, Sudan, Togo and Zanzibar (Suresh Kumar et al., 2005).

Distribution

Several countries grow henna on a commercial scale for its dye-bearing leaves, notably India, Egypt, Iran, Niger, Sudan and Pakistan. In India, it was once grown extensively in Punjab and Gujarat. However, gradually the major cultivation has shifted to the arid fringes of Rajasthan, with Pali district having the maximum area under henna. It is taken as an annual Ratoon crop under rainfed conditions. Presently over 39,000 ha of henna plantations in the district with nearly 70 per cent occurring in the Sojat area produce around 20,000 t dry leaves worth Rs. 40 crores. Besides this, leaf cuttings are also collected from existing farms and field boundary plantations in Gujarat and Madhya Pradesh. In Uttar Pradesh henna is grown for its scented flowers used in the essence industry. Kannauj, Lucknow, and Varanasi in Uttar Pradesh are reputed centres for the commercial extraction of mehndi oil from flowers and its use in traditional essence. Since henna is grown as a dryland crop under limited moisture conditions greater use of available moisture by the plants is possible.

India is a huge importer of crude oil and spends about Rs. 1,200 billion of foreign exchange every year to meet 75% of its oil needs (Anand, 2006). This has affected its balance of payment adversely, especially after the unprecedented rise incrude oil prices. Being an agricultural country endowed with varied climates, nutrient-rich soil and ability to grow many different crops, India offers a great promise as a producer of surplus raw material for biodiesel and bioethanol production. India’s biofuel production currently accounts for only 1 percent of global production (Shinoj et al., 2012). Although all oils can be used, edible oils as a source for biodiesel production have to be ruled out because they are required for cooking and food purposes. Therefore, non-edible oils are the premier raw material for biodiesel production in India. Seeds rich in these oils are mostly produced by perennial species. Hence these trees are referred to as tree-borne oilseed species (TBOS) and they produce TBOs (Aurora and Kumar, 2015). TBOs are cultivated/grown in the country under different agro-climatic conditions in a scattered form in forest and non-forest areas as well as in waste land/deserts/hilly areas. The country has enormous potential of oilseeds of tree origin like mahua (Madhuca indica),neem (Azadirachta indica), simarouba (Simarouba glauca), karanja (Pongamia pinnata), ratanjyot (Jatropha curcas), jojoba (Simmondsia chinesis), cheura (Diploknema butyracea), kokum (Garcinia indica),wild apricot (Prunus armeniaca), wild walnut (Aleurites molucana), kusum (Schleichera oleosa), tung (Vernicia fordii), etc. The best characteristic is that it can be grown and established in the wasteland and have varied agro-climatic conditions. (Aurora and Kumar, 2015)

Of the total land area of the world, arid zones account for 18.8%. Throughout the arid zones, there is no dearth of problems, but rapidly increasing desertification (some call it land degradation) is a problem of worldwide dimension. Water is a scare commodity in arid zones. Much of rainfall is lost by evapo-transpiration and as a result, ground water recharged only by seepage through soil profile. However, it is a common phenomenon in arid zones of the worlds that ground water is frequently used at the rate that exceeds recharge. The situation in arid tropics of India, which is spread over an area of 31.7 million ha, is no more different.

Agriculture is the human enterprise that is most vulnerable to climate change. Tropical agriculture including agriculture in arid tropics, particularly subsistence agriculture is vulnerable, as farmers do not have adequate resources to adapt to climate change. Land-use options that increase livelihood security and reduce vulnerability to climate and environmental change are necessary. Rural folk in arid western Rajasthan, the principal hot arid region of the country have been practising arable cropping in association with these scattered trees on crop fields since time immemorial. This combined protective-productive system of integration of trees into farming system rooted in the principles of ecology, productivity, economics and sustainability, is generally referred as agroforestry. In fragile ecosystems of hot arid regions of India

Rainfed farming has a distinct place in Indian Agriculture, occupying 67% of the cultivated area, contributing 44% of the food grains and supporting 40% of the human and 65% of the livestock population. It is characterized by resource poor farmers, poor infrastructure and low investment in technology inputs (Singh, 1999). The land use in rainfed areas is quite diverse with a variety of crops, cropping systems, agroforestry and livestock farming. The productivity levels have remained low over the years and the share of rainfed crops in the total food grain production has been declining. The rainfed ecosystem suffers from the problems of (i) frequent droughts due to high variability in the quantum and distribution of rainfall, (ii) poor soil health due to continued degradation and inadequate replenishment of nutrient exhaustion, (iii) low animal productivity due to an acute scarcity of fodder and (iv) low risk bearing capacity of farmers due to poor socio-economic base, credit availability and infrastructure.

Indian hot arid zone which is about 12% of total geographical area of the landmass of 0.32 million km² has maximum covering in western Rajasthan i.e. 61% of the total area whereas the other areas in arid region are available in the states of Gujarat, Punjab, Haryana, Andhra Pradesh and Karnataka accounting for 20, 5, 4, 7 and 3% of hot arid area whereas the cold arid area of 8.4 million ha lies in the state of Jammu & Kashmir covering the Leh and Ladakh region.

The hot arid area is characterized by frequent droughts of 47% of frequency in the last century of moderate to severe nature. Due to higher occurrence frequency of droughts in this region of state, the livestock assumes great importance as a drought management measure as agriculture is at the mercy of rainfall pattern which is very uncertain in amount as well as distribution coupled with poor soil condition, higher evapotranspiration and higher wind velocity causing the soil erosion.

For arid region of Rajasthanthe general climatic conditions, topographical features and biotic factors do not encourage agricultural operations in the absence of extractive industry the peasantry has to fall upon animal husbandry as their main occupation. Rearing some of the finest breed of cattle, camel, sheep and goats known for their endurance making much use of the meagre feed resources which are grasses ,herbs, shrubs, tree leaves and cultivated feed and fodder crops. Livestock farming has some in built superiority over crop farming as far as growth; stability and resource conservation are concerned. On an average, the region experiences 3 years of drought in every 10 years. The natural forces constituting the soil-climatic complex, which conspire to reduce the crop productivity and cause instability in agricultural production, have much less impact on livestock farming. This is due to differences in the nutritive value of natural vegetation, which mainly sustains livestock.

Biodiversity is a matter of concern to everyone as most of the economic sectors depends on it e.g. agriculture depends on it for wild genetic resources and biological control, human health depends on nature for many pharmaceuticals, industry requires raw materials which come from the nature, tourism increasingly base its attraction on natural amenities linked to biodiversity, water resources require intact vegetation to protect watershed and prevent siltation, disaster prevention needs natural vegetation to help people to respond to drought and the lists goes on and on (Mc Neely, 2004). Each of these sectors needs to be reminded of its reliance on biodiversity and provided with opportunity to invest in insuring the continued survival of the biological basis of their prosperity. Thus biodiversity has emerged as an integral aspect of human life and hence undoubtedly one of the keystone of sustainable development. Biodiversity in arid lands are under severe threats due to habitat destruction (Manuder and Clubbe, 2002), invasion of species (O’Kennen et al., 1999) dilution of customary conservation practices, climate change (Given, 1994; WCMC, 1992), increasing human population, unsustainable exploitation of natural resources, grazing pressure etc.

Global warming and climate change are becoming major challenges in the front of global community to deal with. Climate change is no more a myth but it is reality. The IPCC, 5^th assessment report clearly stated that “evidence of climate- change impacts is strongest and most comprehensive for natural systems”. Natural and human systems of almost all continents in the world have been affected by climate change in recent decades (IPCC, 2014). Agriculture is essential for sustainability of human life on earth but change in climate is threatening its sustainability. In recent decades all aspects of food security has been potentially affected by climate change, including food access, utilization, and price stability. It has been projected that in absence of adaptation measure, increases in local temperature by 2°C or more above late-20^th-century levels will negatively impact production of the major crops in tropical and temperate regions.

Agriculture is one of the major economic activities responsible for food security and livelihood for millions of people. Success, production and productivity of agricultural crops are highly dependent on climate, soil and water. Thus climate change will have adverse effect on agricultural crops. High atmospheric temperature, unpredicted erratic rainfall, rapid soil degradation and evolution of new insect and pests due to climate change will offer new challenge to sustain agriculture. Many part of the world and India is already experiencing impact of climate change on agricultural crops (like early maturity, geographical shift and occurrence of new pests) and these impacts are predicted to increase rapidly in future. The increasing concern about adverse impact of climate change on food security has led to extensive research and documentation of impact of climate change on field crops like rice, wheat and maize. While the clear and holistic idea about impact of climate change on horticultural crops like vegetables and fruits are not well documented especially in developing countries like India.
