Agriculture being sensitive to changes in the climate, the climate change can have adverse impact on food production and pose prominent threat to food security to the countries in particular and to the world population in general. Climate change refers to any change in climate overtime, whether due to natural variability or as a result of human activity (inter-governmental panel on climate change, IPCC, 2001). It can also be seen as change in climate which is attributed directly or indirectly to human activities that alter the composition of the global atmosphere and which are in addition to natural variability observed over comparable time periods (IPCC, 2007). Climate change has become a global issue in recent times manifesting in variations of different climate parameters including cloud cover, precipitation, temperature ranges, sea levels and significant effects through the production and release of GHGs. Agricultural extension according to Leeuwis (2006) is a series of embedded communicative interventions that are meant, among other things, to develop and/or induce innovations which supposedly help to resolve (usually multi-actor) problematic situations. It has been observed that agricultural extension is involved in public information and education programmes that could assist farmers in mitigating the effects of climate change (MOE FRN, 2003). According to them, such involvements include awareness creation and knowledge brokerage on the issues of climate change; building resilience capacities among vulnerable individuals, communities and regions; encouragement of wide participation of all stakeholders in addressing climate change issues; and developing appropriate frameworks for coping/adapting to climate change effects/impacts.

Introduction India was a self-sufficient nation in its food production before independence but after the occurrence of various famines, the government in late 1960s started focusing more on the crop production i.e.,green revolution (NAAS 2019). Use of hybrids, fertilizers and plant protection chemicals increased and major investments were made on irrigation structures which led to a massive jump in the production of crops. But with time, the negative externalities caused by green revolution were vividly noticeable. The indiscriminate use of chemicals has debilitated the environment by causing soil depletion, pollution, deforestation, climate change etc. thus affecting the health of human kind. The lofty prices of inputs led the farmers to resort to debt thus falling into debt trap and suicides. In order to address this problem an alternative to the conventional farming is required which is more sustainable and climate resilient. In the mid-1990s, natural farming viz., Zero Budget Natural Farming (ZBNF) was demonstrated by Sh. Subhash Palekar also known Subash Palekar Natural Farming (SPNF). It is an agroecology based diversified farming system which involves no financial outlay to purchase essential from outside and makes farming profitable. Mishra (2018) studied on Zero Budget Natural Farming (ZBNF) and found that crops grown under ZBNF evinced higher yield than the crops grown under non-ZBNF.

Introduction In one or another way, agriculture is integral to the physical and economic survival of every human being. The United Nations forecasts that the global population will reach more than 9 billion by 2050. To feed everyone, food production will have to increase 70 per cent. Helping the world’s farmers to achieve this target is challenging in itself, but beyond providing food, agriculture sustains the economies of most countries in significant ways, especially in the developing world (Anonymous, 2018). To meet this challenge in a fast-changing world, new tools, processes and ways of organizing-i.e. innovations-are needed to make agriculture more efficient in economic, social and environmental terms (Hall, Mytelka and Oyeyinka, 2006). Past efforts have tended to focus solely on technology. Previous approaches to technological change in agriculture have been based around supplying technology in a simplistic, top-down manner. These approaches had some success for relatively simple innovations in conducive settings. However, these simplistic approaches are not adequate for the task of meeting the complicated challenges facing agriculture today. Historically, new agricultural technologies have been developed by public research organizations and then transferred to farmers by public extension services (Sulaiman, 2015).

Developing countries with agrarian economy have been facing challenges arising from climate change causes and consequences. The altered patterns of climate are affecting the yield potential of crops thereby affecting agricultural production, farmers’ income, and livelihoods. Out of the 17 Sustainable Development Goals (SDGs) of the United Nations, the 13th SDG on ‘Climate action to combat climate change and its impacts,’ emphasises the importance and urgency of addressing the effects of climate change in developing nations. It is projected that climate change would have the most detrimental effect on agriculture, the primary source of income for small and marginal farmers in developed nations (Azadi et al., 2021). Building the ability of small and marginal farmers will be crucial to global food security over the next decade (FAO, 2020). World Bank (2018) reported that 800 million South Asian population are at risk of experiencing a decline in their standard of living and incomes due to rising temperatures and more erratic rainfall hampering the agriculture production system. Millions of low-income smallholder farmers, particularly those who rely on agriculture for a living and an income in South Asia, would be directly impacted by a reduction in productivity leading to food supply shortages and price increases.

1. Introduction Agriculture has always been greatly dependent on climate patterns and variations, and is considered to be particularly at risk to the influences of climate change (James et al., 2014). Climate change is manifest in the form of reduction in rainfall and drought experienced in the last decade, pushing the agrarian community into real distress (MSSRF, 2020). To reduce the adverse impact of climate change on agriculture, adaptation is considered a crucial component of any policy response related with agriculture and climate change (Deressa et al., 2009). Adaptation to climate change involves changes in agricultural management practices in response to changes in climate conditions (Akinnagbe and Irohibe, 2014). Having knowledge about climatic adaptation practices by the farming communities would make them better equipped to deal with climate change related challenges (Mwazi&Ndokosho, 2011). Though smallholder cultivators are one of the most vulnerable groups to climate change, efforts to support their adaptation strategies are hindered by the lack of information on how they are experiencing and responding to climate change (Harvey et al., 2018). Senapati (2019) argues that farm households with access to weather-related information and extension agency contact have lesser level of vulnerability to climate change and enhanced adaptive capacity. Kavi Kumar (2009) contends the need to have region specific adaptation measures in farming as the key to address challenges of climate change.

Introduction We are faced with the dual challenges of Climate change and food insecurity irrespective of the countries and regions across the globe. Asia Pacific region is one of the most climate change vulnerable regions in the world (Prabhakar & Matsumoto, 2010) on account of its relatively higher & dense population depending on climate related sectors and living in climate change vulnerable locations. In particular, the agriculture production system is facing serious repercussions due to increasing weather vagaries since past few decades. Agriculture being highly dependent on climatic condition is like gambling at the hands of erratic rainfall or droughts leading to crop loss on a regular basis in terms of reduced yield, increased pest resurgence and lack of safety net in case of weather based disasters all of which prominently affects the small holder farm families. Indian subcontinent has been facing extreme climatic events since the past decades in form of floods, erratic rainfall, high temperature, shrinking water sources, etc. which have caused deprivation in agriculture in economic and non-economic terms. In a series of researches and studies conducted over the years; the need for enhanced adaptation research and policymaking capacity in developing Asia has been reflected. Hence, adaptation research has to take an important place at global, national and local level.

India is endowed with diverse agro- climatic conditions which facilitate to cultivate various horticultural crops all through the year in one part of the country or others, but the quality of fruits under open field conditions particularly in high value crops (vegetables & flowers) by and large fall short of domestic and international markets standards. Some time there no guarantee of consistent production of from open cultivation, as the crop is exposed to number of environmental factors that changes frequently. Hence it is imperative to increase the productivity and quality of produce to meet the demand of quality conscious consumers. A break through in production technology that integrates market driven quality parameters with the production system simultaneously ensuring a vertical growth is warranted. In this context, most important technology is the Controlled Environment Agriculture (CEA) i.e. Protected Cultivated Technology (PCTs) such as greenhouse, net house, glasshouse and low tunnel. “Protected cultivation” means modification of plant environment to achieve optimum plant growth avoiding the harmful effect of climatic factors.

1. Introduction The agriculture sector in Asia and the Pacific plays a vital role in the rural economy, making significant contributions to both GDP and employment. This sector serves as a cornerstone for food production, economic growth and poverty reduction in the region. Understanding the importance of farming in the region’s rural economy, as well as the need for viable farming systems particularly for smallholder farms, is essential for sustainable development. Importance of Farming in the Rural Economy Farming has a substantial impact on the rural economy of Asia and the Pacific. It serves as a primary source of income and livelihood for rural populations, contributing significantly to the region’s Gross Domestic Product (GDP). The agricultural sector encompasses a wide range of activities, including crop production, livestock farming, fisheries, and forestry, providing diverse opportunities for economic development. According to the Food and Agriculture Organization (FAO), farming accounts for 29 percent of the region’s GDP (FAO, 2021). This demonstrates the significant economic value that agriculture brings to the region, making it a crucial sector for sustainable development. The revenue generated from agricultural activities supports not only farmers but also other stakeholders in the value chain, including agro-industries, distributors, and exporters.

Introduction Increasing use and rise in the cost of chemical fertilizers, pollution due to their application and decline in soil fertility and micro flora are worrying facts to the farming community. Increased awareness about organic produce among the consumers is another reason to find out an alternative to chemical fertilizers. Vermicompost production on farm and its use in crop production is one way of mitigating these problems. Among the different methods, Windrow method of vermicomposting is the production of compost by piling organic matter or biodegradable waste, such as animal manure and crop residues as long rows (Windrows) on the surface of soil under the shade of trees without any permanent structures and later releasing required quantity of earthworms in wet beds. This vermibed technology is simple and cost effective and sustainable to adopt. The prototypes have been exhibited in the premises of Dairy unit, University of Agricultural Sciences, Dharwad since long and many farmers seeing these were of the opinion that technology was simple and easy to adopt using the farm generated biomaterial waste with no additional cost. During 2020-21, when farmers of remote villages Dharwad district were interacted, it was noticed that still the technology was not followed by the farmers.Therefore, a team of Green Foundation based in Dharwad made an attempt to reach the farmers of remote villages of Dharwad district to make aware of this technology. After interactions with different categories of farmers, a modest attempt has been made to identify small and large farmers of remote villages viz. Basavarsikoppa and Holtikoti of Dharwad district during 2021-22 to sensitize and demonstrate windrow method of vermicompost production. The results, experiences of the farmers and finally the impact of the technology are discussed here in this presentation.

Introduction Large cardamom is an important cash crop cultivated in Sikkim. It is also cultivated in Darjeeling district of West Bengal and some parts of North-eastern state like Arunachal Pradesh, Nagaland and Manipur. It is a low volume, high value non-perishable crop grown organicallyat different altitudes under the trees. The State produces about 4,970 tonnes annually from an area of 23,312 hectares (Spice board, 2021). Among the four districts of Sikkim, North and East Sikkim district contributes largest in terms of area and production of large cardamom (GoS, 2016). Off-late, climate change has become a major concern for the large cardamom growers as many researchers reported its contribution to the decline of its production. Sikkim, as Himalayan states, is endowed with varied agro-climate ranging from tropical in the South to alpine in the North. Shrestha et al. (2010) reported that warming in the Himalayas was between 0.15°C and 0.60°C per decade in the last three decades. Seetharam (2012) revealed that in Gangtok, there is a decreasing trend in maximum temperature while an increasing trend in minimum temperature. The study also depicted the decreasing trend of annual rainfall amount in the study area. In a recent study, Kumar et al. (2020) reported that the warming was more prominent in the last decades in Gangtok and Tadong station, better reflected in the minimum temperature with varied precipitation across the observed period from 1961 2017.

1. Introduction Biochar, produced from pyrolytic decomposition of lignocellulosic biomass, is a solid hard product and a unique green material for soil amendments. Its use has been identified in Amazon fertility as ancient indigenous practice. Through ‘pyrolysis’ (heating without oxygen) process (‘pyro’ which means caused by heat whereas ‘lysis’ means dis-integration), there are three types of yields we get: a solid product (biochar), a gaseous product (syngas/ synthesis gas), and a liquid (bio-oil). The solid item, biochar, is applied for soil amendments. It can be used in agricultural, industrial, and environmental as a functional material. Solid char, a common pyrolytic outcome is charcoal, typically used to designate the solid char product that is ignited for fuel, whereas “biochar” designates the unique solid char purposively used as a soil amendment agent. On the other hand, the gaseous and liquid counterparts of pyrolysis have commercial applications like green energy, feedstock raw materials, and precursors (Fig.1).

Introduction Agriculture has historically been the primary source of income in India. It has the potential to alleviate poverty, increase income, and enhances food security for 80% of both the world’s poor and people who reside in rural areas primarily work in agriculture. One of the most effective strategies to eradicate extreme poverty, increase shared prosperity, and feed an estimated 9.7 billion people by 2050 is agricultural development. Compared to other modes, the agro - based sector’s progress is two to four times more successful in enhancing the earnings of the poorest people (www.worldbank.org). Nearly 5 billion hectares, or 38% of the world’s land surface, is used for agriculture. Around one of this is devoted for farming, and the remaining two thirds are pastures and meadows for grazing animals. Over 10% of cropland is assigned to permanent crops like cocoa plantations, oil palm plantations, and fruit tree orchards. Yet another 21% of land is primed for irrigation, a crucial agricultural land management technique.

Introduction Despite recent significant increases in global food production Sustainable development goal- “End hunger, achieve food security and improved nutrition, and promote sustainable agriculture” seems unachievable. Globally, 1 in 9 people are undernourished, the vast majority of whom live in developing countries. Under nutrition causes wasting or severe wasting of 52 million children worldwide. It contributes to nearly half (45%) of deaths in children under five – 3.1 million children per.Today, the majority of the world’s hungry people—nearly 870 million—live in sub-Saharan Africa and South Asia. Climate change impacts on food security and livelihoods are already alarming and affecting millions of smallholder farmers in sub-Saharan Africa (FAO, 2016). In view of today’s 795 million hungry and the additional 2 billion people expected by 2050, there is an urgent need for a change of global food and agriculture systems in order to sustainably increase food production (UN, 2016). This will exert intense pressure on agro-ecosystems that are already overburdened, particularly in developing countries as most of those increases in production have to occur in this part of the world. The environmental impacts of satisfying this increased food demand will be further aggravated by climate change. With increased frequency and severity of droughts, extreme heat conditions and over dependence on rainfed agriculture, there is a growing agricultural productivity crisis, dwindling household food availability and the economic prosperity of countries whose national economies are dependent on agriculture. Considering that climate change impacts are felt differently within regions, context-specific adaptation measures are required to reduce risks and build adaptive capacity of smallholder farmers (Altieri, M.Aet al.2017).

Introduction India has one of the world’s largest agricultural production areas of land. The net sown area is 140.1 million hectares, the net irrigated area is 49% of this, which is 68.4 million ha as per 2014–15 land-use statistics (Agriculture Research Data Book 2019). While the proportion of Indians employed in agriculture is decreasing, agriculture, along with its allied sectors such as livestock, forestry and fisheries, remains India’s primary source of income. As per the Lok Sabha Standing Committee on Agriculture (2019–20), agriculture and allied industries employed 54.6 percent of India’s total workforce. Approximately 70% of rural households still rely primarily on agriculture for a living. Agriculture and allied sectors’ share of the country’s Gross Value Added (the value of goods and services produced in an area, industry, or sector of an economy) has fallen from 18.2 percent in 2014-15 to 16.5 percent in 2019-20. As per current trends, 60% of India’s population (more than 10% of the world’s population) will face severe food shortages by 2050.

Introduction The idea of LiFE was introduced by the Prime Minister during the 26th United Nations Climate Change Conference of the Parties (COP26) in Glasgow from 31st October to 13 November 2022. The idea promotes an environmentally conscious lifestyle that focuses on ‘mindful and deliberate utilisation’ instead of ‘mindless and wasteful consumption’.(PIB India) The LiFE Movement aims to utilise the power of collective action and nudge individuals across the world to undertake simple climate-friendly actions in their daily lives. The LiFE movement, additionally, also seeks to leverage the strength of social networks to influence social norms surrounding climate. The Mission plans to create and nurture a global network of individuals, namely ‘Pro-Planet People’ (P3), who will have a shared commitment to adopt and promote environmentally friendly lifestyles. Through the P3 community, the Mission seeks to create an ecosystem that will reinforce and enable environmentally friendly behaviours to be self-sustainable.

Introduction The intergovernmental panel on climate change (IPCC) which takes account of on historical, psychological, social , physical and economic and political perspectives of climate change in its report, released in November 2014 said that the Working Group I contribution to the IPCC’s Fifth Assessment Report (AR5) considers new evidence of climate change based on many independent scientific analyses from observations of the climate system, paleoclimate archives, theoretical studies of climate processes and simulations using climate models. Climate change is not controversial as naysayers and some media would convey. After decades of careful observation, collection of data, and tracking of changes in the climate system, there exists a solid, scientific consensus that human-caused climate change is a reality (Michael, 2012). In their report, the NCSE 2015 says that there is substantial scientific agreement about the occurrence, causes, and consequences of climate change. Yet due to the inherent complexity of the topic and the social controversies surrounding it, confusion and doubt often persist. Here, we need to develop the workforce, education, and training for climate-smart Agriculture. The following are some interventions.
