Preface   Extension science with respect to Agricultural and allied fields has undergone a metamorphosis over a period of several decades in India and across the globe. It has been vibrant, dynamic and aids in bringing about remarkable changes in the livelihood of peasants across India. Any science which fell in line with the pace of change of the system in which it is operating, ready to accept challenges and evolve pragmatic strategies, models, policies can thrive and contribute to the humankind. Hence, it is imperative for extension science to change according to changing needs of its clientele. Climate change has brought in tremendous changes in the way the agriculture is being practiced. Fragmentation and shrinking of land holdings, water and labour shortage, changing food habits of people, shift towards high value horticultural crops, enhanced thrust for quality aspects and value addition of agricultural commodities and other plethora of factors resulted in ‘Agriculture’ being viewed as ‘Agribusiness’. In such a scenario, Indian farmers are craving for a different type of Extension system which could deliver a variety of information through innovative modes. In response to the shift in farmer’s requirement, several Central and State Government interventions were put in place and their results were mixed. National level Institutional arrangements like ATMA, ATIC and state specific arrangements like Krishi Bhavans of Kerala, DATTS of Andhra Pradesh etc., brought significant change in technology delivery. Group based Extension, Market led Extension, ICT enabled Extension, Participatory Extension, Youth and Women Inclusive Extension, Extension plus are some of the conspicuous shifts observed in Extension approaches. Several Extension Service Providers like Central, State departments, State Agricultural Universities, Private Firms, NGOs have been trying different approaches and models of technology delivery to farmers from time to time. The contours of Agricultural technology transfer across the globe has been realigned with the Public Extension is slowly replaced by several models. We need to identify Good Extension Practices (GEP) as that of Good Agricultural Practices which can be thoroughly debated and replicated in appropriate locations. The management of this change contemplated through several new approaches and models of Extension holds the key. Hence, a multidimensional and honest stocktaking of what has happened so far and what is required to be done in terms of Extension Research and Field Extension is the need of the hour. This warrants deliberation of higher order which resulted in creation of new knowledge and cross learning. The Extension scholars and researchers need to share their unique experiences in research and communicate the concepts that they have developed and experimented. This sharing will enrich the Extension science in one hand and the scientists who share will get a research network for themselves. Keeping the noble cause of dissemination of research findings in Extension science in mind, this edited book has been prepared through collection of precious research articles from eminent Extension scientists and scholars across India. They were addressed to contribute papers on Institutional arrangements for technology delivery, innovative Extension approaches, break through methodologies in Extension research, the reach and effectiveness of ICT tools in technology delivery, youth and gender inclusive extension strategies and Extension strategies for changing scenario of Agriculture.

The field of talent management continues to mature from agri-business to extension service, but it is also being impeded both by the scale of debates taking place. The field continues to agree that talent management “adds value” to the organisation such as extension system. To understand the development scenarios of strategic talent management, we need a “theory of value” to understand the elements of talent management which are the most valuable for business-led extension service (BLESS) effectiveness. “Theory of Value” is a generic term which encompasses all the theories within economics that although explain the exchange value (or) price of goods and services. Alternatively, “Value of Theory” encompasses a range of approaches in extension system to understand how, why, and to what degree humans should value things, whether the thing is person, idea, object, (or) anything else for effective functioning of strategic business-led extension service to sustain its clients system.

1. Prelude Indian agriculture has experienced spectacular changes in the recent period, manifesting large-scale commercialization and diversification. They broadly include cultivation of new crops and varieties, increase in the share of area under cash crops, large scale spread of livestock activities and fisheries, pursuance of high tech in the areas of aquaculture, bio-technology, horticulture, processing etc. India currently is the second largest food producer. If we look critically the resources available with the country we can say it has the potential to be the world’s number one producing over 600 million tons of food products.

Though the extension education was originated as a “field approach” aimed to enhance the life quality of rural people, it has evolved into a scientific discipline that relies heavily on empirical research to develop and test its “field-oriented” approaches and methods. Since its birth, the extension research has passed through several phases and a range of research paradigms like community mobilisation, farmer participatory approaches, technology assessment and refinement, impact assessment, Information and Communication Technologies (ICTs) aided development, etc.

Farmers require a diverse range of information to support their farm enterprises. Information is needed not only on best practices and technologies for crop production, but also for post -harvest aspects. Agricultural Extension is an essential pillar for research and development in agriculture. Despite a wide range of reform initiatives in agricultural extension in India in the past decades, the coverage of, access to, and quality of information   provided to marginalized and poor farmers is uneven. Approaches to agricultural extension in India and worldwide continue to evolve.

1. Introduction Democratisation of information makes it possible for ideas, opinions, knowledge and services to be accessible to everyone, anywhere, anytime. In this era of ‘knowledge sharing’, making access to the required information and knowledge is the key to innovation and empowerment of farming community. Rapid technological developments over the years, particularly internet and mobile, have made it possible to provide array of services on a single platform due to convergence. It is a unique opportunity to leverage upon the available ICT infrastructures and deliver the knowledge based services effectively to people. There are number of ICT initiatives being attempted in the field of Agriculture and other sectors. Some of the successful models (web-based and mobile based) have shown way for the future of e-extension in India.

Agriculture is vital to the development of any nation, India being no exception. Development must include the youth and therefore the government seeks to encourage their participation in the agricultural sector. This effort seeks to change the negative perception the youth have of participation in agriculture as uneducated, unskilled, physical labourers with extremely low economic return. Modern agriculture is more than tilling the soil and animals. The sector today offers career opportunities in research, environment, financial management, engineering and other technical areas for the youth to explore. The introduction of the Youth in Agriculture is necessary and important to facilitate food and nutrition security for the sustainable development of the nation.

Throughout the history of Indian agriculture, the contribution of farmers to agricultural technology development and dissemination has been very significant. Farmers’ practices are useful not only for scientific technology development, but also for sustainable agricultural development. Rural economy will sustain only when it effectively utilise the available local resources. But recent agricultural development witnessed that those modern agricultural practices slowly replacing the farmers’ practices. In this juncture the basic challenge for sustainable agriculture is to make better use of these internal resources. This can be done by minimizing the external inputs used, by regenerating internal resources more effectively or by combinations of both (Rolling and Pretty, 1997).

Tamil Nadu Irrigated Agriculture Modernisation and Water Bodies Restoration and Management project (TN IAMWARM) is a multidisciplinary project funded by World Bank. It is being implemented by WRO, PWD as nodal agency in 63 sub basins along with line departments and TNAU as coordinating agency since 2007. TNAU is concentrating on up scaling water saving technologies including Sustainable Sugarcane Initiative (SSI) under Precision farming in sugarcane. Krishi Vigyan Kendra, Virinjipuram is implementing TN IAMWARM project in Cheyyar & Kiliyar sub basin since 2007. Cheyyar  and  Killiyar Sub - Basin are the tributaries  of the Palar Basin that rises in KolarDistrict of  Karnataka enters through Vaniyambadi  and drains an area of about 13,470 Sq. K.M. of which 10,880 Sq. K.M. is in Tamil Nadu. The command area of this sub basin comes under the Cheyyar and Vandavasi Taluk in Thiruvannamalai and Uttermerur, Maduranthagam, and Seyyur Taluk in Kancheepuram Districts  which covers 458 tanks in 12 blocks with a registered ayakut area of 36746 ha. The major crops grown in the sub basin area are paddy, sugarcane, groundnut and pulses.

Vegetables constitute about 55 per cent of horticultural crop production in the country with a total production of 85 million tonnes which is estimated to cross 100 million tonnes in near future. Successful cultivation of vegetables is hampered due to the incidence of several insect pests. Cultivation of hybrids, improved varieties, intensive agronomic practices, off season cultivation and indiscriminate use of insecticides has changed the pest complex in these crops.

The Revised ATMA Scheme provides for dedicated specialist and functionary support to take up training and extension initiatives at State, District and Block level. Besides this, improvement in extension outreach right down to the village level is expected to be achieved through Farmer Friend. The study mainly focused on farmer friend under ATMA scheme. The FF served as a vital link between extension system and farmers at village level (one for every two villages). The FF should be available in the village to advise on agriculture and allied activities. The FF  mobilized farmers’ groups and facilitate dissemination of information to such groups, individual farmers and farm women directly through one to one interaction individually or in groups and also by accessing information / services  on behalf of farmers as per need through Common Service Centres (CSC) / Kisan Call Centres (KCC). (Government of India, 2010).

Krishi Vigyan Kendra is a Government of India funded Indian Council of Agricultural Research Project implemented at district level for enhancing the productivity and livelihood through scientific extension works. Realizing the importance of technology dissemination in the changing scenario of food and nutritional security, ICAR intervened in a big way. All the first line extension projects were merged and brought under single umbrella of KVK. The major emphasis was to enhance the production and productivity as well as to generate household income and employment of farming community. It was also envisaged that these extension works will be act as model for extension agencies and also catalyzed to improve the existing systems for better delivery mechanism.

Rice is a staple food for millions of people in the world, particularly in developing countries like India. The demand for rice is growing with ever increasing population. In India more than 70 per cent of the ground and surface water is being used for Agriculture and out of this 70 per cent is allocated to rice cultivation. Each kg of rice produced with irrigation requires 3000- 5000 litres of water (Anonymous, 2011). The demand of rice in India is increasing with increase in population and is expected to be 140 m.t. by 2025 (Pandey et al., 2008).

Theworld fashioned and occupied by three fourth of the water. Fisheries activities are an indispensable part in the life and livelihood of the peoples. Aquaculture is the most important role for the upward economic strengthening and social mobility. Most of the inland fish farmers are poor due to lack of financial resource. Because of the poor production through the inland fish culture, the most of the farmers in Tamilnadu are undertaking composite fish culture technology. Demand for fish is rapidly increasing due to the growing population and awareness about the superiority of fish to other meats. The marine and freshwater sectors growth were 2.5 and 8 per cent respectively (Ayyapan and Diwan, 2004).

Groundnut is one of the main oilseed crop of India.Unlike many oilseeds, Groundnut can be consumed directly in various farms and hence now it is also being considered a supplementary food crops. In india groundnut is grown in an area of about 6.5 hectares with a production of  about 7 million tones of pods per annum (2007). It is one of the few crops that can be cultivated even on marginal lands under low input conditions. Unfortunately average productivity of groundnut in india is quite low (1000kg) compared to (USA-3000 kg/ha, China- 2600 kg/ha, Argentina-2100 kg/ha  and  Indonesia-1550 kg/ha).

In any work environment the managers, facilitators are equipped with some specific type of skills to perform their activity effectively. In this study, multi stakeholders were involved in the process of Precision Farming from land preparation to marketing. Every stakeholder has a specific task to be performed so as to lead the client in the direction desired. In order to achieve this, the skill components viz., Management and Facilitating skills possessed by them and their own perception on those skills were assessed.

Farmer Field School (FFS) is a capacity building method based on adult education principles for group of farmers. FFS is best described as a ‘school without walls’, where farmers learn through observation and experimentation in their own fields. FFS methodology is potential extension approach to enhance farmer’s knowledge which is a basis for adoption of improved practices (Manoj and Vijayaragavan, 2014). In Andhra Pradesh Department of Agriculture initiated FFS programme in the name of Polambadi during 2006.

Food security is an essential feature of a country’s independence and sustenance. Rapid growing population and increasing purchase capacity, both play an influential role on food security. The cultivation or agriculture has declined the world over, with India and Kerala being no exceptions mainly due to the lack of human resources to work with the soil. Uneconomic crop pricing, lack of social accreditation, poor and unstable income, insecurity to life and health etc. are the main factors which discourage the youngsters in our country from becoming ‘farmers’.

Agricultural practices have been undergoing changes over a period of time throughout the world. The intensive agricultural practices followed during the past four decades in our country resulted in food security and self-sufficiency. This was achieved through development of input responsive varieties coupled with use of chemical fertilizers and plant protection chemicals. Agriculture is an important sector for economic development in India. Crop production is an important income source for millions of farmers in some cases with few cropping alternatives due to ecological constraints. All over the world majority offarmers rely on pesticides and fertilizers to increase yields. Pesticide use in most Indian agriculture is an essential part of production technology. Therefore farmers in developing countries are perceived as overusing pesticides, both in quantity and quality, with mixtures of chemicals, known locally as cocktails, being the favoured form of application (Crissman et al., 1994).

The cropping pattern in India is changing fast, particularly in favour of export-oriented commercial crops. These crops pose threat to the environment. Grapes is one such crop which accelerates environmental degradation. Borkar (2007) reported that with the advancement of technologies, the cultivation practices of grapes had improved increasing the yield and quality of grapes. However, to control the tremendous losses occurred due to pests and diseases in grapes, thousands of hundreds of kilograms of pesticides were dumped into the environment causing pollution.

Fish has a vital role to play in mitigating the protein deficiency in developing countries. Fish has been described as the meat of the third world, and fish contributes significantly in developing and developed countries as a source of employment, income generation and foreign exchange earnings. The minimum per capita consumption of fish of an average Indian should be 11 kg per annum, as recommended by the ICMR. However, the per-capita consumption of fish in India is only 5 kg per annum, whereas, per capita consumption of fish in Japan was 62.6 kg, China - 30 kg and Bangladesh - 35 kg (Goswami et al., 2012).

Agriculture is the key force in India and nearly two-third of the work force is directly or indirectly depends on agriculture to support their livelihood. In every day situation, farmers are facing complex problems viz., pest hazards, weed control, moisture insufficiency, soil fertility, farm credit, labor shortage, soil erosion, crop production technologies and so forth to improve the production and productivity. It is not sufficient to give agricultural related information to farmers alone and it is very essential to give information on newly released technologies to the people involving in the extension activities or extension personnel’s.

Distribution channels are behind every product and service that consumers and business buyers purchase everywhere. Product distribution is one of the four elements of the marketing mix. Usually, combination on institutions specializing in manufacturing, wholesaling, retailing and many other areas join force in Distribution channels. A Distribution channels are a set of inter-dependent organization involved in the process of making a product or service available for use or consumption. Distribution channels decisions play a role of Strategic importance in the overall presence and success a company enjoys in the market palace.

Animal husbandry contributes 30 percent of agricultural gross domestic products in India and hence remains an important livelihood activity to the growing population of India. Mixed and diversified farming provides significant profit to the farmers than either only with agricultural or livestock farming. One of the biggest challenges in animal production is to produce animal products for human consumption through sustainable technologies. In the southern districts of Tamilnadu, dairy farming, sheep and goat rearing and back yard poultry form the major livestock livelihood activities.

Agricultural sector worldwide is faced with several serious challenges as follows the spiralling demand of food, declining agricultural productivity due to natural resources degradation and increasing competition in international markets. The new millennium throws up new challenges in the Indian agriculture sector that are different from those in the past. Continuous pressure of producing more food from the same land with shrinking natural resources and marketing the product is a tough task for farmers. Public agricultural extension system with a mandate and mission, beyond transfer of technology, is needed to develop the capacities of the farming community.

Climate change is a complex problem involving varied interactions between the environment, natural resources (land, crops, animals and water) and people. These interactions are likely to change the ecological and agricultural landscape, and therefore influence agricultural and animal production. The Intergovernmental Panel on Climate Change (IPCC) has dictated that global warming/climate change could lead to many environmental problems i.e., Drought, floods, crop and animal farming, food production, and health hazards etc. Agriculture is closely dependent on the endowment of natural resources and environmental conditions of soil and climate. India is divided into many agro—climatic zones depending upon rainfall, agriculture and soil fertility. The agro climatic conditions of India and the various other factors that largely determine the cropping patterns vary throughout the country. Warangal district falls into two agro climatic regions namely Southern Telangana Zone and North Telangana Zone.

India’s agrarian culture and economy is undergoing drastic changes. In this progressive path of agricultural resurrection, a comprehensive multidimensional understanding of agricultural development is of great importance. In the present context of Kerala, where the local administrative bodies are vested with more powers to plan and execute need based agricultural development activities, a clear understanding of the concept of agricultural development among the major stakeholders shall serve as a firm base for development.

The digital revolution is radically shifting how people create, manage, share and publish information, as well as how they relate, collaborate, communicate and share resources. Information and Communication Technologies (ICTs), Social Media, Web 2.0 and mobile applications have also significantly changed the livelihoods of the local farmers especially in developing countries.

Water is one of the most important production assets and securing access to and control and management of water is key to enhance livelihood base of any country like India where most people depends on agriculture. India is endowed with rich and vast diversity of natural resources, water being one among them. But water resources in India are unevenly distributed over the country. The more than 50 per cent of the total resources distributed with five states namely Uttar Pradesh, Odisha, Andhra Pradesh, Karnataka and West Bengal (MWR, 2008) and left other states much prone to water scarcity.

Technology adoption is mounting every day in the field of agriculture. The greatest need of the day is to effectively communicate the information related to farm technologies to the millions of farmers to educate and to adopt them in order to modernise their agriculture. Inspite of our best efforts, only 25 to 30 per cent of the modern agricultural technologies have reached farmers. This modern technology however has been restricted to favourable farming situation only.

Today, in many countries mobile phones are being used by farmers, not only as a person voice communication medium but also to provide access to  information through sending message service (SMS), multimedia messages service (MMS) and access to the internet. Across the developing world, there are programmes that give farmers access to research and best practices, weather information and market prices via SMS, Interactive Voice Response (IVR) or call centers.

The ICT enabled extension systems act as a key agent for changing current agrarian situation by improving access to information, sharing knowledge, providing incredible opportunities and enabling the empowerment of farming communities. In order to extend the benefits of ICT’s to the disorganized and disadvantaged farming sector, one of the road maps to achieve them are access of ICT’s to villagers through Mobile telephony.

The transfer of technology keeps the wheels of agriculture development moving. The existing transfer of technology mechanisms and extension programs are either slow or ineffective in bridging the linkages between the research community and the farmers. Information Communication Technologies (ICT) in agriculture is an emerging field focusing on the enhancement of agricultural and rural development. The advancements in ICT can be utilized for providing accurate, timely, relevant information and services to the farmers, thereby facilitating an environment for more remunerative agriculture.

In India, self employment has been recognized as an essential force of development in rural areas. It has emerged as a strategy designed to improve the socio-economic life and mainly focuses on extending the benefits of development to the poorest in the rural areas improving their standard of living and self-realization. SHGs in India are integrating the low income segments with rest of the rural community by ensuring them a better contribution in a more equitable share in the benefit of developments. These Groups are not only speeding up economic growth, but also providing jobs and improving the quality of rural life towards self-reliance. Self-employment needs a very wide ranging and comprehensive set of performance, relevant to all aspects of rural economy and covering rural people including skilled, unskilled and landless labours and artisans of Rural India. The Rural Indians put their entrepreneurial skills in all the rural development performance  but their economic status has not improved to the expected level. They have much potential, despite they are ignorant of converting their skills into reality.

e-SAP is one of the important emerging and efficient dissemination tool for agricultural pest management. e-SAP refers to electronic solution for  agricultural pest management. e-SAP is a ground – breaking application built on the backdrop of agricultural pest management. Its foundation lies on a unique platform that facilitates the storage access and transfer information between all stakeholders in agriculture. It enables rapid and delivery of farm data in various forms including multimedia to researchers, policymakers and other users in real time.

Web-education Technology “Educating the people through web” this process is called web-education. The World Wide Web provides new opportunities and hopeful future for distance education over the Internet and the distance education is becoming a widespread used for quite a long time through Newspapers, Radio and TV. Now-a-days mostly the World Wide Web (WWW) getting vital role in distance education, e-learning and distance learning since the networking technologies are emerging very rapidly in the media dominant era. The connectivity of the internet to different kind of people around the world is increasing steadily, like TV and Radio. The World Wide Web and other Internet–based collaborative modern communication technology tools have significantly enhanced the ability to train and educate people electronically.

Information Technology can play an important role in disseminating agricultural information to the farmers by using various multimedia sources. Farmers are more desirous and anxious to get quick, accurate and authentic information in the changing scenario of agriculture at local and at global levels. Dissemination of the required and recent agricultural information to the farmers in scattered villages at the variegated geographical situation in India is very difficult task. Transfer of technology to farmers is not a one time exercise because new farm technology is being constantly evolved. A continuous flow of technologies in an appropriate manner is vital to provide quick benefit for the development of the farmers. There has been a technological explosion in the field of agriculture. This demands that the farmer has to know all aspects of technology prior to its adoption. Hence Interactive Multimedia Module (IMMM) has potential to reach the unreached.

Information and Communication Technology is ruling the world in all walks of life and access to mobile phones and internet facility is growing in India at a rapid rate in recent years. However, the access to internet based technologies have confined primarily to the urban areas. Rural communities have not been able to gain to the same extent from IT. As a means of agricultural technology transfer to farmers, information technology has had a limited impact.

Kerala State receives an average annual rainfall of about 3000 mm but with high variability. The demand for water in Kerala is mainly for drinking, agriculture, power generation and aquaculture as well as for prevention of salt-water intrusion. Currently 71 per cent is used for irrigation , 18 per cent for domestic use and the rest is for other purposes. However, Kerala is one of the States with lowest per capita water availability among the Indian states. Basak (1998) reported the per capita water availability in Kerala was only 69 per cent of that of the country in 1981 though the general perception is contrary to this.

The Indian agriculture is on the threshold of a second revolution. It is becoming increasingly clear that the next leap will come from the Information and Communication Technology (ICT). Even though ICT has developed very well, its penetration to the farming community seems to be very less. At the same time, it is difficult for the extension agent to personally attend the queries of every farmer individually. With the decreased number of extension workers, there is a need to use the latest technologies for delivering extension services.

Indian economy is basically an agrarian economy (Saxena, 2012) and the majority less literate and unskilled population living in rural areas does not fit into the employment market. Employing 55% of labour force, agriculture sector is a major employment provider (Chand, 2014). However, the seasonal nature of Indian agriculture leads to seasonal and cyclical unemployment. This situation can be altered by generating employment opportunities through nurturing entrepreneurship in agriculture (Rehman et al., 2012).

The prosperity and growth of a nation depends on the status and development of women as they constitute about 50.00 per cent of the human resource of the country. Women play a significant role in agriculture and allied fields. She also performs several management and decision making roles in farming and home making practices with her male counterpart and sometimes alone.(Sreenivasulu and Punna Rao, 2005). Khelkar (1995) found that 64.55 per cent had medium level of farm management followed by high and low 18.18 per cent and 17.27 per cent respectively.

Women hold up half the sky’ according to Chinese saying. This is true with the Indian scenario as well, since women make up half the country’s population. The rural women in India constitutes nearly 77.00 per cent of the total female population. About 79.00 per cent of rural women workers are involved in agriculture related pursuits as cultivators and labourers. Farm & home are integral parts in the rural society in India and the ‘house wifes’ in the farmstead often plays multiple roles as producer, entrepreneur, workers, consumers, and homemaker. Women are more sensitive than men to the extremes of poverty and its consequences.

World-wide, both in developing and in developed countries;family farming is one of the most predominant forms of agriculture. It includes a wide spectrum of farm sizes and types. In high-income economies, it ranges from very large land holdings that are easily cultivated by one or two family members with the use of labour-saving machinery and hired labour. In low-income economies,with small holdings of a few hectares or less and that are often oriented towards subsistence with low marketable surplus.

There are 437 tribes in India and Andhra Pradesh is inhabited by 33 tribes. Of these, 13 tribal groups  inhabit in high altitude zone of Visakhapatnam. Livelihood security is the ability of a household to meet its basic needs like food, health and shelter, basic education and community participation. Livelihoods can be made up of a range of on-farm and off-farm activities which together provide a variety of procurement strategies for food and cash.

The College of Food Technology was established in the year 1976 at Parbhani as one of the constituent College of VNMKV, Parbhani. Food Technology College involves the knowledge of application of different fields of food Science and also includes transfer of Food Science technology to the students to make them well equipped with knowledge and skills required for employment in public  and private sector.

In the semi-arid tropics, where small farmers depend heavily on rain-fed agricultural systems, variability in precipitation has a dramatic impact on crop production and livelihoods. Because small-scale agriculture depends on rain-fed cultivation, it is vulnerable to factors such as flooding and drought. Unfortunately, the frequency of unexpected heavy rainfall or flood events has increased in many areas of Africa, including Southern Zambia. About 75% of farmers in Zambia engage in small-scale farming, with an average farm size of 2 ha (VAM Steering Committee Zambia, 1998). Most of these farmers cultivate maize, which is a staple food in Zambia, and stable maize production and increased productivity are important both for food security and to provide a livelihood to farmers.

Tank irrigation is passing through a critical juncture in India today. Tank irrigation contributes significantly to agricultural production in India in general, and in Andhra Pradesh, Tamil Nadu and Karnataka, in particular. The tank irrigation system is one of the vast networks of thousands of water bodies that constituted a distinctive landscape which was medieval in origin but still the basis of livelihood in the dry Southern plains(Mosse, 2003, P-4). Tank is a small reservoir constructed across the slope of the valley to catch and store water during rainy season. Water is controlled by sluices attached to the tank bank and is delivered to paddy field by distributing channels. Tank is considered as a common property resource. The National Sample Survey Organization defines common property resources as the resources that are accessible to and collectively owned, managed by identifiable community and on which no individual has exclusive property rights (NSSO, 1999).

Cassava is one of the leading staple food crop which is consumed as food and rest is used in industries and as feed to animal. Cassava has the potential to increase farm income, reduce rural and urban poverty and help to close the food gap (Nweke et al., 2001). It is used in many sectors like food processing, textile industries, glucose production etc. Salem stands first in area and has about 650 sago and starch industries acting as a prime reason for the intensive area under the cassava cultivation in Salem also 60 per cent of the starch produced in India comes from Salem District alone. Nearly 200 products can be made from cassava which leads to implementation of several interventions in the district which helped in imparting knowledge on cassava value addition techniques and improve adoption. Present study was undertaken to analyse the perceived impact by focusing on the effect of interventions of CTCRI and TNAU among the women growers in enhancing group approaches and empowerment through entrepreneurship activities.

Sustainability issues have infused sanity in utilizing interventions without much damage to the environment. The wisdom of the practitioners, who had over generations developed their own eco-friendly practices, is being appreciated. Recent researches have aimed at documenting, rationalizing, and blending the Indigenous Knowledge with the so called Scientific or Western knowledge so as to take care of the sustainability issues. Many researchers have contributed to this pool of knowledge by documenting many of the technologies, crop wise, area wise and operation wise and so on.

Climate change referred as, a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods (IPCC, 2001). In other words, it is any long term conspicuous deviation from usual prevailing climate bringing variations in normal temperature, rainfall, atmospheric circulation with abnormal expression in extreme climate such as floods, droughts, extreme temperature etc.

In conventional agriculture, spatial variability over the landscape is ignored and fertilizers, herbicides, insecticides, fungicides etc. are applied at a uniform rate throughout the crop field. Precision Farming emphasizes on the infield variability which is first recognized, located, quantified and recorded, then managed by applying farm inputs  in specific amounts at specific time and at specific locations.

Livestock sector plays a vital role in the welfare of India’s rural population by acting as an important source of income and employment in the rural sector (Dastagiri, 2004). India possesses the largest livestock population in the world and ranks first with (520.6 million), and accounts for the largest number of cattle (world share 16.1%), buffaloes (57.9%), second largest number of goats (16.7%) and third highest number of sheep (5.7%) in the world (FAOSTAT) and sustaining all these in less than 5% of world’s and one-third of Asia’s agricultural land area (MOA, 2003).

The agricultural production is inherently a risky business characterized by seasonality; perishability and variability which make it susceptible to vagaries of climate and markets and thus farmers face a variety of agricultural risks. In response to these risks over a period of time, several risk management mechanisms have been evolved. Risk management strategies refer to ex-ante measures taken before such an event has taken place, whereas risk coping strategies are, ex-post strategies dealing with the consequences of the event (World Bank Report, 2005). Invariably, farmers use both ex-ante and ex-post strategies. It is interesting to note that so far agriculture risk management has been in terms of risk avoidance and risk reduction and mostly these risks are addressed at farm or production level. Currently there has been a shift in agriculture risk management from risk avoidance and risk reduction strategies to risk mitigation strategies. Similarly, there exist shifts from production to market orientation in agriculture. To understand this phenomenon involved, it is felt necessary to study the agricultural risk management behaviour farmers. Keeping this discussion as focal point, the study was conducted with an objective to assess risk management behaviour of farmers.

Rationale of the Study Greens are the cheapest of all the vegetables within the reach of poor man, being richest in their nutritional value. The problem of malnutrition is assuming seriousness in the vulnerable groups viz., adolescents, pregnancy, lactation and school children, not because of poverty but because of ignorance, illiteracy and callousness of the people. The lack of knowledge especially on the nutritive value of these green leafy vegetables among the public in general is the main drawback in their lower consumption. (Jyoti, 2008)
