Abstract

The known views in society about the biotech foods were collected and structured in statements. An opinion survey of sixty scientists of CCS Haryana Agricultural University on these statements was conducted. Half of the scientists agreed that there were no biotech food products in our country. Biotech foods were considered safe for human consumption by 61.7% of the respondents. A large majority of the scientists considered that biotech foods were different in taste from foods made from conventional crops. Similarly 65% of scientists had the opinion that biotech crops increase food allergies. Fifty percent of the scientists agreed that biotech foods were regulated and tested. The rest opined that labeling is needed for biotech foods even in USA. Overwhelming majority felt that biotech foods were not widely accepted. Meat, milk and egg products from biotech animals were not concieved as unsafe to eat by 43.3% respondents. Equal number of scientists felt the same about foods produced through biotechnology and viewed that these were not tested for health.

Abstract

Self Help Group (SHG) has emerged as a new paradigm for combating poverty and self help promotion has become one of the major developmental strategy in the country today. The self help groups are motivated to take up suitable micro entrepreneurship for income generation either individually or in groups, which is dependent on the resource availability and their skills. The empowered SHG women have started different small enterprises such as papad making, malt preparation, different value added products, and other agro based industries which has increased their income. In recent years agro processing and value addition to the farm produce have attained great socio economic significance. A massive thrust to food processing and other agro based industries will add value to the product there by increasing the income of farmers, create employment opportunities, diversify rural economy and foster rural industrialization.

Abstract

The food security scenario in South Asia has witnessed rapid progress over the last few decades, yet nutrition outcomes, especially those related to women and children, have failed to keep pace. This paper contends that the role of women in providing food and nutrition security at the household and individual level needs to be examined, if the paradox of persisting malnutrition amid macro level food sufficiency is to be resolved. Food security, in its broader connotation, results from the availability of adequate food, effective consumption, and desirable nutrition outcomes. As such, it is intricately linked with a woman’s multiple roles expressed in her productive, reproductive, and caring functions. However, even focused efforts aimed at resolving the problems faced by women in performing one or other of their roles, may fail to produce expected results, if the issues underlying each function and their inter-linkages are not fully understood. The paper thus attempts to review various aspects of the relationship between women and food security in South Asia, highlights the issues that require urgent focus and indicates emerging concerns in the region.

Abstract

Farm women are the backbone of Indian agriculture. They contribute more to food production and family income in terms of skilled and entrepreneurship than is generally known or accepted. Thus the governmental efforts to reach the development goals may be jeopardised by not taking into account the women’s contribution to agriculture. In this age of scientific development farm women have not participated to the extent they are expected in agriculture because they are not recognized as tangible contributors to agricultural development. They always remained as invisible workers in spite of their pivotal role and remain silently behind all the efforts of men. Very few scientific and empirical investigations have been made to examine the actual participation of farm women in crop production and dairy production activities. Taking the above situation into consideration, four minuscule studies were conducted in Bangalore, Mysore, Mandya and Chamarajanagar districts of Karnataka to know the level, extent and nature of participation of women in home, farm and livestock production activities.

Abstract

The present paper examines the effect of fodder cutting and uprooting activity on the cardiovascular system of farm women. The research design comprised of field study conducted on 30 farm women. The activity of cutting and uprooting were studied with the traditional tools as well as with the improved tools. Newly designed and developed slashing knife and uprooter were provided to the respondents for performing the activity of cutting and uprooting. The results revealed significant reduction in average working heart rate (2.08** - cutting and 4.99** - uprooting; Significant at 5% level) and peak heart rate (-3.55**- cutting and 1.70**- uprooting; Significant at 5% level).  It was found that there was significant reduction in muscular stress after use of improved tools over the existing tools.

Abstract

The present study aims to assess postural and muscular stress among farm women performing weeding and winnowing operations. Postural stress was assessed through postural deviation in spinal curvature, energy expenditure, physical cost of work, cardiac cost of work, pain in different body parts and muscular stress was assessed by percentage decrease in grip strength. Postural deviations were recorded with the help of flexi curve. Heart rate was calculated in 3 phases: before, during and after the work. Energy expenditure, physical cost of work, cardiac cost of work was also calculated. Grip strength of both hands was calculated by grip dynamometer. The mean value of ergonomic parameters were found more in weeding operation which were as follows : -Postural deviation (250), Average heart rate (5.35), energy expenditure (5.70), physical cost of work (3.05), total cardiac cost of work (35.82). After weeding operation farm women perceived very severe pain in lower back, buttocks, and palms, while after winnowing they experienced very severe pain in shoulder, upper back and upper arms.

Abstract

Sericulture, an agro-based industry contributes significantly to Indian economy.  Silk cocoons are reeled on charaka, cottage and multiend reeling machines. Of these more than 50% of raw silk comes from charaka sector. Charaka silk reeling units decreased from 23971 to 16263 (1998-2003) in Karnataka. These charakas are mostly operated at grass root level with labour coming from small, marginal and land less villagers. A study was conducted in 15 charaka reeling units in two taluks each of Bangalore rural, Mysore, Kolar and Chamarajanagar districts. Respondents were grouped into small (1-4 charakas), medium (5-8) and large charaka reelers (>8). Primary data was collected with pre-tested schedules.

Abstract

Women of sixteen villages in Bhadra wildlife sanctuary were interviewed for assessing the role of women on forest policies and conservation of natural resources. Survey conducted during 1996-1997 indicated that women in general declined to comment upon natural resources. Ninety percent of women had no knowledge about natural resources. Except for Fire Protection Act women had no knowledge of other government policies. They had no say in policies and conservation of natural resources in Bhadra wildlife sanctuary. As a result there has been encroachment of forest area, cultivation in forest land, shifting cultivation, hunting, smuggling, open cast mining and deforestation. To make role of women active and effective for conservation of natural resources in Bhadra wildlife sanctuary, suggestions have been advanced in this paper based on a survey.

Abstract

The total Indian population is 1027.01 millions of which women account for 495.73 millions (2001 census). Women constitute about 48.27 percent of the population. The labour force participation of the women is 51.6 percent. In rural India, agricultural and allied activities employ as much as 89.5 percent of the female labour. Women have an active role and extensive involvement in livestock production, forest resource use and fishery processing. They contribute considerably to household income through farm and non-farm activities as well as through landless agricultural labours. They are deprived of exposure to knowledge and hardly participate in the process of decision-making. Female agricultural labourers are the poorest section of Indian society. Despite the women’s role in agriculture there has been a lack of adequate attention towards gender issue in the area of agriculture research.

Abstract

Role of women in agriculture is a well-known fact and is unquestionable. The changing trend in agriculture technology, use of modern tools, and wider participation of community is crucial in making farming activity as an attractive field of employment. While most of the young and male population is shifting to urban areas for wage based non-agriculture activity, women have to bear the burden of agriculture in villages. The drudgery faced by women in farm activiies need to be reduced and value addition to the farm products is required at home  scale/community scale in the villages. Newer and economically viable systems need to be introduced at village level with ample scope for women to participate in these activities. Women should not only be partners in agriculture but they also should take lead in entrepreneurship and in value addition. Further marketing systems for the products need to be established. 

Abiotic stresses are major constraints for many crop plants in specific areas over the globe which limits the crop production. Dudal (1976) estimated that only 10% of world’s arable land may be categorized as free from stress. The rapid change in environmental conditions likely to override the adaptive potential of plants, this environmental changes mainly originated from anthropogenic activities, which has caused soil and air pollution, plant are exposed to natural climatic or edaphic stresses, such as, high irradiation, heat, chilling, freezing, drought, excess water and waterlogging and nutrient imbalance. Among abiotic stresses drought is the main abiotic factor as it affects 26% of arable area (Table 1.1). Water stress is a single most severe, limitation to the productivity of rice in the rainfed ecosystem (Widawgky and O’Toole, 1990). Mineral toxicity/deficiencies are second in importance. Among mineral toxicity, salinity is wide spread and is estimated to affect 10% of the world land surface (Richards, 1995).

2.1. INTRODUCTION

Salt stress has become an ever increasing threat to food production. It is a major factor limiting the crop productivity in the arid and semi-arid areas of the world (Ashraf, 1994; Foolad and Jones, 1992) and it affects about 10% of the total global land area (Richards, 1995). Increased salinization of arable lands is expected to have devastating global effects, resulting in 30% land losses within the next 25 years and up to 50% by the year 2050 (Wang et al., 2003).

Soluble salts can cause harm to plant, if they are in high concentration in water or soils and it limit crop cultivation world wide. Generally an array of stresses interplay in saline soils and reduces productivity of salt sensitive crops. In India, about 12 mha of land has been affected with salinity and alkalinity (Yadav and Gupta, 1984); an area of nearly 4 mha of land suitable for rice affected with salinity (Paul and Ghosh, 1986). The optimum salt concentration for the growth of halophytes is found to be about 0.5 M NaCl (Flower and Yeo, 1981). Most of the crop plants are salt sensitive glycophytes.

3.1. INTRODUCTION 

Transitory waterlogging occurs extensively in both irrigated and dry land agriculture on clay flats and duplex soils. Most of the humid tropical lowlands, with adequate, rain-fed but poor drainage, have the problems of waterlogging, which is further intensified by low water table and poor root aeration. In submerged condition, only root is exposed to excess water and the injury to the shoot is not a primary effect.

The term ‘waterlogging’ is defined as a condition of the soil where excess water inhibits gas exchange of roots with the atmosphere. Waterlogging is different from ‘flooding’ because the latter results in addition factors of partial or complete submergence of the shoot. The waterlogging replaces a gaseous air by liquid water, leading to the gas stresses. Schematic representation of adverse effects of waterlogging on plant growth and survival has been given in Fig. 3.1.

4.1. INTRODUCTION

Water stress is the single most severe limitation to the productivity of rice in the rainfed ecosystem (Widawsky and O’Toole, 1990). Drought has been defined as the inadequacy of water availability, including precipitation and soil moisture storage capacity, in quantity and distribution during the life cycle of the crop to restrict expression of its full genetic yield potential. Drought is actually a meteorological event which implies the absence of rainfall for a period of time, long enough to cause moisture-depletion in soil and water deficit with a decrease of water potential in plant tissues. Under drought conditions, water stress develops in the plants as the demand exceeds supply of water; this may occur either/or both due to atmospheric or soil conditions, and is reflected in a gradient of water potentials developed between the soil or soil-root interface and leaf, the transpiring organ. Moisture stress is likely to develop to a different rate in different plant organs along with the gradient. Drought like many other environmental stresses has adverse effects on plant growth and yield.

5.1. INTRODUCTION

Temperature is the one of the most important environmental element influencing the plant growth and development limiting the productivity and adaptation of crops, especially when it coincides with critical ranges (Chen et al., 1982; Paulsen, 1994). Nearly all commercial crops in the arid and semi-arid tropics often suffer from heat stress. Every plant has an optimal temperature for its normal growth, deviation from this may cause stress to plants. The adverse effects on plant of temperatures higher than the optimal considered as heat stress. Crops are exposed to periods of heat stress during their life-cycle. The optimum temperature for the most species ranges from 25 to 35 0C. Above this value, a decline in the photosynthesis rate is observed (Berry and Bjorkman, 1980; Pimentel, 1998). Even brief periods of heat-shock between temperature ranges of 45-50 0C induce marked change in plant growth processes.

6.1. INTRODUCTION

Low temperature is one of the major environmental factors that limit the plant growth. Many plants of tropical origin suffer cold damage when exposed to temperature below 20ºC (Graham and Patterson, 1982, Andrews, 1987). Cold temperature in crop plants are compounded by cold snap– a lower than usual drop in temperature that causes the crop to fail. Low temperature in growing season may reduce germination, retard vegetative growth by inducing metabolic imbalances and can delay or prevent productive development. Each plant species has an optimum range of temperature for its normal growth and development. It varies among the genotypes within a species, the specific temperature also depends on the growth stage and development of the particular genotype.

7.1. INTRODUCTION

Abiotic stress is a major limiting factor in crop productivity. Several stresses, such as high temperature, high light intensity, osmotic stress, heavy metals, and several herbicides and toxin lead to over production of reactive oxygen species (ROS), causing extensive cellular damage and inhibition of photosynthesis (Allen, 1997). ROS is produced in both unstressed and stressed cells. Plants have well developed mechanisms against ROS, involving both limiting the formation of ROS as well as instituting its removal. Under unstressed conditions, the formation and removal of O₂ are balance. Introduction of molecular oxygen (O₂) into atmosphere by O₂- evolving photosynthetic organisms, ROS has been the unwelcome companion of anaerobic metabolism. In contrast to O₂, these partially reduced or activated derivatives of oxygen (O₂¹, O2-, H₂O₂, and HO) are highly reactive and toxic and can lead to the oxidative destruction in tissues during stress.

8.1. INTRODUCTION

Aluminium (Al) is not considered as essential nutrient, but at low concentrations it may increase plant growth or induce other desirable effects (Bollard and Butler, 1966; Foy, 1988; Huang et al., 1992a, b; Roy and Mandal, 2005). Al affects about 40-70% of the world arable land, which has the potential for food crops biomass production (Haug and Caldwell, 1985). Acid soils constitute about 3.95 billion hectares globally. About 38% of those are present in Tropical Asia (Datta, 2002). It is believed to cover more than 800 million hectares of forest and tropical Savana ecosystems of tropical America (Jaffe and Rojar, 1994; Prakash 2000). Nearly 75% of Amazon Basin contains acid and infertile soil classified as oxisols and utisols. About 383 million hectares (79%) of the Amazon area, suffers from Al toxicity. Acid soil occurs extensively in the some of the Mediterranean countries and Southern Australia. Low laying acid sulfate of Bay Islands in India chronically suffer from Al-toxicity (Chowdhury et al., 2001).

9.1. INTRODUCTION

Iron (Fe) is important component of a plant’s energy-power house chlorophyll. It also interacts with all the major enzymes and proteins at higher concentration in the soil, and it is toxic to plants. Fe-toxicity creates a range of nutrient disorders and deficiencies of P, K, Ca, Mg, Mn and Zn in plants. These elements were reported to play decisive roles in manifesting toxicity symptoms in rice (Sahu, 1968; Ottow et al., 1983; Yamauchi, 1989; Sahrawat et al., 1996). Excess absorption and translocation of Fe in the rice plants led to toxicity, which has been a major limiting factor in wetland rice. Average yield loss due to Fe-toxicity accounts to 50% and in fact ranges from 10-100% (Brigit et al., 1993).

10.1. CADMIUM
10.1.1. Introduction

Cadmium (Cd) is a strongly phytotoxic heavy metal in an increasing environmental problem worldwide. It is one of the most dangerous metal due to its high mobility and the small concentration at which its effects on the plants being to appear. It is released into the environment by the power stations, heating systems, metal-working industries or urban traffic. It is recognized as an extremely significant pollutant due to its high toxicity and large solubility in water (Pinto et al., 2004). Soil solutions which have a Cd concentration ranging from 0.32 to 1.00 mM can be regarded as polluted to a moderate level (Sanita di Toppi and Garbrielli, 1999).

11.1. BORON TOXICITY
11.1.1. Introduction

Boron (B) is essential micro-nutrient. It is necessary for cell wall formation, membrane integrity, calcium uptake and carbohydrate synthesis and transportation. B affects many functions in plants, which includes flowering, pollen germination, fruiting, cellular activities (division, differentiation, maturation, respiration etc.), water relationships and the movement of hormones. It is not translocated and leached easily from soils.

12.1. INTRODUCTION

Air is polluted when it contains enough unhealthy particles and gases to harm human beings, animals, plants and even objects such as building and statues. Air pollutant may present as solid, liquid or gas form. Industrial revaluation in the 19th and 20th centuries leads faster increase in concentration of air pollutants in the atmosphere. The most important air pollutants that damage the plants’ growth and development, subsequently the economic yields of crop plants are ozone (O₃), nitrous oxides (NO₂ and NO), carbon monoxide (CO), ammonia (NH₄), peroxiacetyl nitrate (PAN), sulphur dioxide (SO₂), hydrogen fluorides (HF), particulate matters (cement dust, magnesium-lime dust, carbon shoot etc.), smoke etc. Burning of hydrocarbons in motor vehicle engines gives rise to CO₂, CO, SO₂, and NO in varying proportions and ethylene (C₂H₄) as well as other hydrocarbons. Industrial plants release SO₂, H₂S, NO₂ and HF into atmosphere. Hydrogen peroxide (H₂O₂) is another potentially injurious molecule, can form by the reaction between O₃ and naturally release volatiles (terpenes) from forest trees.

13.1. INTRODUCTION

Photosynthetically active radiation is a primary energy resource for terrestrial plants, necessary for the plant growth. Plants receives this photosynthetically active radiation from sunlight as a consequence, plants are also exposed to the ultraviolet (UV)-radiation. Seven percent of the electromagnetic radiation emitted by the sun is the UV range (200-400 nm). Though representing only a small portion of the total solar electromagnetic spectrum, UV-B has a disproportionately large photobiological effect. As it passes through the atmosphere, the flux transmitted is greatly reduced, and the composition of the UV-radiation is modified. This UV-radiation is mainly divided into three classes, namely UV-A, UV-B and UV-C. The UV-A region of the spectrum (wavelengths from 320 to 400 nm) are not attenuated by ozone, so their influence will be unaffected by ozone layer reduction. This portion of the UV radiation is less damaging and important for photomorphogenic signal in plant development (Bjorn, 1994). The wavelength of UV-B portion ranges from 280 to 320 nm. This region of UV is very energetic and effectively absorbed by ozone in the stratosphere. Thus, only a very small portion, approximately 4% is transmitted to the earths. Shortwave UV-C radiation (200-280 nm) is highly energetic and strongly absorbed by atmospheric oxygen and ozone. Thus, none of this sterilizing radiation is present in terrestrial sunlight.

14.1. INTRODUCTION

The climate of a place is the average weather that is experiences over a period of time. It is the natural phenomenon that has occurred throughout the history of the earth. Climate change is strongly associated with higher temperature, altered precipitation, and higher levels of atmospheric CO₂ and other greenhouse gases. It is a very slow process; it takes a long time to settle in. Climate change in IPCC (2007) usage refers to any change in climate over time, whether due to natural variability or as a result of human activities. Over the last 150-200 years the changes to our climate are happening more quickly now than they have ever done before in the geological past. Human activities have altered natural climatic processes at a geographically rapid pace by booting atmospheric concentrations of several greenhouse gasses. Following are the changes taken place over years of industrial age (IPCC, 2007):

India is on the move, but in part.  
For, the farm sector is lagging behind.
It may soon become a drag on the economy.
Hence, farm development requires renewed efforts,
Farm youth must get critical attention.
Matter brooks no delay.

Farming is still the only source of human subsistence. No alternative is in sight. This ancient family occupation has survived over the ages through a process of transfer from father to son, generation to generation. But, in recent times, with an unprecedented externalization of farming, and under the pervasive influence of Liberalisation, Privatisation and Globalisation, this process of transfer of occupational knowledge within the community is seriously dislocated. Also, the earlier institutional arrangements for formal education in farming like district agricultural schools, gramsevaks training units and farmers training centres have now disappeared. In the meantime, even as more rural youth are becoming literate, formal education system is seen to have shed all aspects of agricultural education. Thus, the rural drop-outs are missing both formal and informal orientation in farming since a comprehension of ‘modern’ farming is beyond the middle level farmers. As such, farm youth today are neither here nor there, with regard to farming.

There appears a general consensus that agriculture sector in India requires to be revitalized to enable it to respond effectively to the multitude of challenges that it now faces, and include assuring food security and environmental sustainability against the background of declining natural resources, changing climate and needs to become increasingly competitive.

Sustainable agricultural practices cover a whole range of improving sustainability: raising soil fertility, improving water storage capacity, increasing water quality, diversification, raising people’s capability to cope with risks and withstand natural calamities, reducing energy consumption, minimizing risk, and so on.

It is impossible to achieve sustainable development without applying sustainable agriculture on a large scale. The relationship between agricultural production and eradication of extreme poverty and hunger is very strong: agriculture is the very basis for food security. Together with fisheries, it provides practically all of the world’s food.

Agricultural production systems depend on natural resources viz. land, water, biodiversity, forests, pastures and wildlife. Farm activities can also have major impacts on the quality and availability of these resources well beyond the boundaries of the production system. Although natural resources are critical to agricultural production, farm households also frequently depend on them to meet other needs, such as fuel, construction materials and supplemental foods. Thus rural livelihoods are intricately linked to the condition of natural resources. Over the last 40 years as food production has doubled, agricultural production systems have expanded, with significant impacts on the natural resource base:

The World is a home to more than one billion young people aged between 15 and 24 years.  Many are unable to fulfil their potentional because of poverty, hunger, poor health and lack of education. As a result, they lack the skills needed to gain employment, with rural youth typically, but often fruitlessly migration in search of economic opportunities. However, given support and opportunities for gainful employment, young people have the potential to play a significant role in agriculture.

India has a big advantage as more than half of its population is below 30 years of age.  Indian agriculture will receive a big boost if the country takes advantage of its young population and encourage them into farm sector by making it lucrative.  It is necessary to launch a Youth for Agricultural Transformation Movement in rural India. Youth can provide demand driven services such as farm health monitoring and marketing of biological software essential for sustainable agriculture, climate-risk management, organization  of bio-parks, food parks, bio-village, bio-industrial watersheds and improved post-harvesting technology. Educated rural youth can establish Village Knowledge Centres (VKVs) to provide information at right time to farmers. Home Science graduates can establish nutrition clinics to help hidden hunger through appropriate local grains and vegetables (Swaminathan, M.S.). Why Youth in Agriculture?

The world is changing rapidly and education is facing new challenges as we move into the 21st century. For Extensionist, this means new approaches to teaching and learning are needed. Futurist John Naisbitt (1994) predicts that as structured employment opportunities decline, entrepreneurial skills will become necessary for the rural youth to compete. Additionally, acquiring skills and attitudes necessary for the youth can be achieved through youth entrepreneurship programs (Cox, 1998)

There is a challenge to convert ideas into policy and then into action to put in programmes aimed at helping the future farmers of the world.  According to UN report , Youth as a target group is not a major policy priority of most governments in developing countries. This review illustrates that youth are only occasionally visible in policy related documents.  Hazelman  (2008) emphasized based on lessons from case studies made by FAO in Asia and the Pacific,  highlighted  the importance of having a clear national policy relating to rural youth; building and utilizing youth networks and partnerships at the national, regional and international levels; organizing youth into youth-led organizations that are active and have strong leadership together with competent and committed advisors, with projects and activities that address youth and community needs; and giving priority and attention to education and training opportunities for continued learning and human-capacity building.

While on one hand, more than 25 per cent of rural population in India is between 15 and 29 years of age, on the other, very little demographic dividend in agriculture is being derived. Unable to find decent employment, youth often look for employment in the urban informal sector, with poor working conditions and pay. But without training in skills suited to the urban labour market, these youth have few opportunities in the urban areas. Inadequately trained to compete successfully in urban labour market, they often suffer varying levels of poverty and marginalization in towns than in rural areas. In rural areas, if young farmers do not replace the ageing farmers, it will result in problems related to food security. For young people to take to agriculture, farming must be personally satisfying, mentally challenging, socially acceptable and economically rewarding. However, field reality is something different.

The Agriculture sector is by far the largest employer amongst all the major sectors employing roughly half of available workforce. At the same time, agriculture is the smallest sectoral contributor to the GDP. It is ironical that the most important requirement of human being, which is the bulk of agriculture farm produce, is largely considered to be an unrewarding sector in the nation.

Though the Indian agriculture has made significant strides in the course of the last 50 years of planned development, still the farmers today are facing the consequences of host of challenges, namely dependence of monsoon, declining size of land holdings, degradation of soil & water resources, declining investment of public sectors on agriculture. So farmers are increasingly getting indebted and temptation to sell their farm land  for non-farm purposes is growing. Over 45 per cent of farmers want to quit farming says a survey conducted by National Sample Survey Organization (NSSO).

Agricultural land is still a great source of income. But the practice of unsustainable methods and improper resource management leading to successive crop failures that make agriculture non- profitable and highly  risky.  So, the interest of youth in agriculture has been declining. While most developing countries are still experiencing high population growth rates, the youth are migrating in significant numbers to urban areas. The younger generation does not consider farming as a profession and they treat it as traditional activities of their family. The farm youth think that the farming system is not capable to provide a life, therefore they are diverting from agriculture to other profession.

Youth of today are the hopes of tomorrow.  They are the backbone of a country.  Youth reflect the national potentiality and represent the life blood of a nation. The future of the country lies in their hands.  What they will become, what they will do, what role they will play in the free democratic society, will depend, to a greater extent, on the period between childhood and adulthood.  They are the most potent segment of the population of a country. It is they who are to shoulder responsibility for the future development of the country.

The socio-economic development and prosperity of the rural areas depends, to a considerable extent, on the type of the youth the country side has, because the rural youth have abilities to orient themselves to go along the main stream of the development process.  The youth, a bulk of total population of the country, are the national cream and the future crown with full possession of physical built and mental tenacity and power. They are the precious human assets who can play an important role in nation building activities if opportunities are provided.  If a country can harness a creative and pervasive force like youth, it can substantially and quickly advance towards modernization. Youth are the nation builders of tomorrow. They are not only carriers of new ideas and are more receptive to new ideas, ready to bear risk and willing to work as a Team.

Indian agriculture is at demographic, ecological, economic and technological cross-roads. Demographically, nearly 70% of the population is below 35 years in age and 70% of them live in rural areas.  Within the next few decades, India will have the world's largest number of young people looking for employment.  Ecologically the basic life support systems of land, water, forests, biodiversity and climate are in distress and the population supporting capacity of major ecosystems is being exceeded in most parts of the country. India's ecological debt and Nature Deficit Disorder are growing. Economically, the cost-risk-return structure of farming is becoming adverse, with the result that over 40% of today's farmers would like to quit farming, if they had another livelihood option. Technologically, there is a serious mismatch between production and post-harvest technologies. Also, there is no nationally agreed policy towards the technological transformation of agriculture, involving farm mechanization and frontier technologies like recombinant DNA technology and nano-technology.

Today around 25% of rural population in India are between the age group of 15 and 29 (2001 Census).  The Tenth Five-Year Plan (2002-2007) has estimated that India's labour force will increase faster than the ability of the economy to create new working opportunities. The country is adding 2 million young people to the ranks of the unemployed every year. The Plan document estimates that open unemployment could be as high as 5% at the end of the Tenth Plan period, from 2.8% at present.  This is likely to entail tremendous costs, including social unrest and dislocation resulting with large number of youth are unemployed or underemployed.
 
In India and in many developing countries the majority of the work force is employed in agriculture. However, stagnating agricultural productivity and rural environmental degradation have made agriculture a last option.  As the environment on which their livelihoods depend becomes more and more degraded, rural youth face diminished prospects of employment.  Not only do these youth lack income, they lack a means of gaining respect and a sense of belonging in their communities.  Unable to find decent employment, youth often look for employment in the urban informal sector, with poor working conditions and pay.  But without training in skills suited to the rural labour market, these youth have few opportunities in rural areas.  Inadequately trained to compete successfully in rural labour markets, they often suffer worse levels of poverty and marginalization in rural areas.

Youth constitute a numerically dominant potential, resourceful and adventurous segment of the population in India. The share of population between age group 0-14 years dropped from 43% in 1971 to 41% in 1981, however the share of population age 65 has been fairly stable at 3% since 1971. In 1991, youth population in India with the age group of 15 to 35 years was around 31 per cent (246 millions) of the total population.  Out of this total youth population, 20 per cent (53 millions) were urban youth, while the remaining 80 per cent (211 million) were rural (Shivalingaiah, 1995). According to 2001 census, India had a total youth population of 347 millions (i.e. 35.2 per cent of the total population), out of which, about 70 per cent were rural youth and the remaining 30 per cent were urban youth. Since major segment of this population are being lived in the rural areas, they are considered as the nation builders of tomorrow. This important section of the rural population can respond to the needs of country only if they are offered fruitful opportunities for growing up as useful citizens. Today unemployment is a major problem among the rural youth which forced them to migrate from rural areas to urban areas. Indian villages are, therefore undergoing major transformation causing perceptible changes in aspirations of the rural masses, especially the youth. These aspects have been dealt in greater detail in some papers (Sharma, 2006).

The progress and prosperity of a nation depends to a large extent on well trained and disciplined youth. The youth of today are the adults of tomorrow and farm families of the future. More than half of the India’s population is below 35 years of age. Majority of these young people live in village where they do not have adequate opportunities for vocational training and formal schooling. This vast youth population has limitless energy and enthusiasm. The proper chanalization of this energy for constructive work can make India one of the most developed and prosperous nations of the world. Youth are the future of India, it is therefore, essential to harness them in an organized manner to build up the backbone of the country. If they are given good training they grow up as individuals-physically, mentally and morally capable of playing their full part as adult members of our welfare society.

Youth, defined as those who belong to the age group of 13-35 in the National Youth policy 2003 of India, is considered to be the most vital segment of the population. Across the globe youth is being treated as an asset for a country’s development and enormous investment is being made to develop the human capital. The challenge of nations like India with ‘Youth Bulge’ in their population is to channelize the energy into positive and creative development process. Youth in the 21st Century aspires for a just global order,  They are looking for democratic process in all spheres of life, whether it is education, employment or decision making.  The issues and concerns of youth are fast changing in tune with the technological innovations.

The livelihoods of millions of rural households in the semi-arid areas depend mainly on natural resources such as soil, rainwater, vegetation, livestock and the like. The major source of livelihood in these areas solely depends on the arrival, distribution and cessation of monsoons, which are erratic and ill distributed. However, management of natural resources like soil and vegetation in a way that these are used to optimally to produce maximum output. This requires new knowledge, better skills and improved management strategies. In this context, building the capacity of the rural households particularly the youth holds key to improving productivity and profitability ot the enterprise. Keeping these in view, the National Agricultural Innovation Project (NAIP) sub project on “Sustainable Rural Livelihoods through Enhanced Farming Systems Productivity and Efficient Support Systems in Rainfed Areas” being implemented by a consortium led by CRIDA has introduced several interventions aimed at involving rural youth right from the beginning of the project.  The project is being implemented in eight backward districts (Adilabad, Anantapur, Kadapa, Khammam, Mahabubngar, Nalgonda, Rangareddy and Warangal) of Andhra Pradesh in selected clusters of villages.

Youth in India had been at the forefront of the nation’s struggle for freedom and development. There are over one billion youth in the world today. Eighty five per cent of these youth live in the developing world and around 50 per cent of the population with in developing countries live in rural areas. According to 2001 census, more than 40 per cent of the total population is between the age group of 15 to 35 which is considered as “youth” by the Government of India. Out of which, 73 per cent resides in the rural areas (Anonymous 2001). Unfortunately rural youth of today are counted among the most disadvantaged groups of society. Because of rapid population growth, widespread unemployment inadequate health, poor education, migration, lower family income and lacking adequate opportunity at farm level had led the rural youth in continued stress of self esteem and self confidence. Youth empowerment is an attitudinal, structural and cultural process whereby young people gain the ability, authority and agency to make decisions and implement change in their own lives and the lives of other people. Youth are the present and the future of humanity.

Though gender is universally one of the key ways in which societies and culture allocate rights and responsibilities, yet the different roles of women and men in agriculture production have frequently been ignored in research and extension activities. Farming is a family enterprise involving both men and women. The role of women and their involvement is more important in production, processing and storage of grains and vegetables. Women in India constitute nearly half of its population and have a strong influence on the growth of the remaining half of population.

Krishi Vigyan Kendra imparted learning through work experience and concerned with technical literacy. Krishi Vigyan Kendra imparted training to practicing farm women. The Krishi Vigyan Kendra of Gandhigram Rural Institute was established in July 1989 specifically to cater the needs of the peasants of the Dindigul district.  Inspite of these efforts, there exist a wide gap-between the availability of production technologies and adoption of those technologies. Evaluation of training programmes organised for farm women would provide an understanding of their effectiveness so as to improve them. Hence, a study was undertaken to assess the training needs, appropriate season, venue, type, frequency, duration and method of training in paddy crop as perceived by the respondents.

The Government of Tamilnadu has taken a number of progressive measures on water resources and irrigation management, particularly through the Bank -assisted Tamil Nadu Water Resources Consolidation Project (WRCP) which was closed in September 2004 with a satisfactory rating. Now the Tamilnadu Government has decided to implement a project for the modernization of the Traditional Irrigation systems in Tamil Nadu with loan assistance from World Bank. The World Bank has also come forward to assist the Tamilnadu Government’s proposal. Under the World Bank funded project of “Irrigated Agriculture Modernisation and Water Resources Management” (WRCP - II) about 17 River sub basins have been selected and proposed to be taken up under the control of Water Resources organisation Wing of Public Works Department of Tamilnadu. The Varahanadhi sub basin is one among the seventeen. Accordingly this ‘IAMWARM’ Project report for the modernization of the irrigation systems of Varahanadhi Sub Basin has been prepared. The very objective of this project is to attain maximum productivity from farm lands, for which serious attention is required to modernise the existing irrigation structures, anicuts, canal systems and tanks in order to make them functionally more effective, conserve and utilise the available water from catchment area for optimum use.

Agriculture is the main stay for majority for people in India for their livelihood as 55 per cent of population depends directly or indirectly depends on the agriculture. The farmers still follow the traditional farming system and practices. Food grain crops are dominating in the cropping pattern. The share of commercial crops in cropping pattern though rising is not significant. The condition of the farmers is such that they have lost interest in farming. The new generation has no interest and is away from farming. The new generation does not consider farming as profession and they treat it is traditional activities and family tradition. The present generation thinks that the farming system is not capable to provide a life, therefore, they are diverting from agriculture to other profession. The major problem for rural youth is non-availability of self-employment options except farming in Rural India. Therefore, rural youth are either migrating to urban area or becoming the causal labor.
 
In order to keep the rural youth in agriculture, there is dire need to create the employment opportunities in rural area. In rural area, agriculture is the major primary source of employment. In such condition, development of agriculture based entrepreneurship is the best option to keep the rural youth in agriculture. A number of agriculture based enterprises can be promoted. By introducing elements of entrepreneurship in farm business, the farming community will be able to combine land, labour and capital in right proportions.

A large portion of India’s population lives in the villages where still against many odds smaller units of village industry sector are struggling for survival. Abject poverty, no year round employment avenues, poor access to basic infrastructure, market, illiteracy and small holdings are few among tangible features of rural India. Desai (2007) has high lighted that poor infrastructural facilities in rural segments has been one of the factor holding back rural industrilisation in India.

On the other hand with liberalisation and globalisation of economy and the removal of quantitative restrictions the khadi & village industries including agro based industries are facing stiff competition. The situation has ultimately resulted in continuous migration of unemployed rural youth to nearby urban areas. Very few among immigrated rural youth are getting absorbed due to mechanisation in urban industries, leaving others in distress. Gopu (2007) viewed that unbridled growth of industries in urban areas has accented the regional disparities in India. Despite planned industrialisation efforts in the country agriculture remains largest industry or major occupation providing employment to 65 per cent of rural work force. In this, situation, expansion of rural industrialisation can play a vital role in abating distress migration and create employment opportunities to rural youth.

Generating productive and sustainable employment for growing populations is a challenge faced by many developing countries in Asia. In India, the daunting numbers further compounds the task. Approximately 65% of the country’s billion plus population is below the age of 45. The Tenth Five-Year Plan (2002-2007) has estimated that India’s labour force will increase faster than the ability of the economy to create new working opportunities. The average growth rate of employment in India, which stayed above 2% per annum during the 80s and the early part of the 90s, fell to only 1.1% in the late 90s. The country is adding 2 million young people to the ranks of the unemployed every year. The Plan document estimates that open unemployment could be as high as 5% at the end of the Tenth Plan period, from 2.8% at present. This is likely to entail tremendous costs, including social unrest and isolation. India’s planners have set the country a goal to create 100 million employment opportunities over the next 10 years.

India has the second largest concentration of tribal population after African continent. The tribal population of India is more than 8 per cent of the total population (Anonymous 2001). However, in Maharashtra it is over 9 per cent of the state population. Among the tribal community Bhil community is the largest tribal population in Maharashtra. They live in compact areas, which are generally hilly and undulating terrain. The Bhil are primarily farmers, though they are said to be hunters since the past. Poor condition of soil, small holdings, poor resources and economic condition, traditional methods of agriculture do not provide them a regular and continuous sustenance throughout the year as such they have to depend on other subsidiary sources of earning.

Most of the tribal communities have to live under a difficult economy; the ways of their livelihood are limited and work very hard to get a bare subsistence. Thus, the tribal children from their early age are burdened with a number of economic duties, obligations and they can hardly be spared for school. Proportion of dropout is also higher among tribal children. In fact most of the tribal youth and school going children participate in farming and looking after the economic demands of the family.

Indian dairy sector has made significant progress over the last few decades. Despite three decades of cooperative movement in India, however, a large proportion of milk and milk products in India continues to be marketed through the ‘informal or unorganized sector’. Although the share of organized market has steadily increased over the last few decades, the informal sector comprising middlemen, private milk traders and direct sale from producer to consumer, still accounts for nearly 80 percent of existing milk marketing pattern in the country. Milk contributes more to the national economy than any other farm commodity more than 10.5 billion dollars in 1994-95 (Dairy India 1997). In the context of poverty and malnutrition, milk has a special role to play for its many nutritional advantages as well as providing supplementary income to some 70 million farmers in over 500,000 remote villages (Dairy India 1997).  In their study, Datta and Ganguly (2002) reported that if the current growth continues for the next twenty years (the nation has been growing at a rate between 5 and 7 percent over past five years), milk consumption is likely to more than double by 2020. So above the discussion drives us to analyse the marketing behaviour of dairy farmers.

The study area, Tamilnadu, was selected purposively and out of seven agro-ecological zones in Tamil Nadu, western region has been selected purposively as it highest share in both the bovine population and milk production in the state. And both organized and unorganized milk marketing system working in this zone with largest number of milk plants.

As rural populations decrease, so does the agricultural work force. In Europe and North America, agriculture now represents about 5% of the work force. In Africa and Asia, it is expected that the number of agricultural workers will have decreased from nearly 70% of the population in the 1980s to barely 50% by 2015 (Crop life International, 2010). The events of the past few years have highlighted the vulnerability of global food security to major shocks – both in the global agricultural markets and in the world economy. The food price crisis and the ensuing economic crisis reduced the purchasing power of large segments of the population in many developing countries, severely curtailing their access to food and thus undermining their food security. “We estimate that in 2012 there will be over a million children suffering from severe acute malnutrition – what’s important to know is that malnutrition can kill,” UNICEF’s Director of Emergency Programmes, Louis-Georges Arsenault, said in a news release. “We need more resources to really scale up our response before it becomes too late and too many lives are lost.” Sahel and other regions in the Horn of Africa are facing severe food crisis (UN, 2012). In such a condition, to feed the hungry mouths of the world, agriculture needs to be more modern and decisions should be information and knowledge based and not instinct-based. Information and communication technology has a great role to play here.

In this era of information and communication, in a country like India where more than 75% of population live in rural areas, radio is the cheapest medium available in almost all families for entertainment and education.

A community radio (CR), in essence is a type of radio service that caters to the interests of a certain area, broadcasting material that is popular to a local audience but is overlooked by more powerful broadcast groups. It is usually established by the efforts of a specific community, operated by the community and for the community’s welfare. Radio can play an effective role in promoting social change.  Community radio station is one that is operated in the community, for the community, about the community and by the community.  It can play a very important role in bringing about social change. It covers all developmental and rights based issues, and can help to sustain the diversity of the local cultures and languages. It is an effort towards bottom-up approach to address specific requirements or rural Indian population. An attempt has been made to know the profile characteristics of krishi community radio listening farm women, awareness of farm women about FM krishi community radio and to study the usefulness of krishi community radio programmes as perceived by farm women.

Agricultural research in India has contributed new varieties of crops and production technologies for increased production at the national level. These modern technologies benefited only a particular section but farm youth in rainfed areas are facing many problems. One of the problems identified in the diffusion of technologies to farm youth in sustainable agriculture was the lack of appropriate technologies suitable to the farm and social situations. When farmers in rain fed areas are exposed to innovations, they react to the practices/innovations from different viewpoints. A practice appropriate to farm youth in rain fed areas must be less in cost, high in profits, less risky,  highly compatible with socio-cultural values and beliefs, less in complexity, highly trialable on a small scale and the results of the same should be easily observed and communicated. These dimensions are perceived by farmers differently and the degree to which they perceive them favourably are likely to adopt the same in rain fed areas. Many a time, several past investigations have only indicated whether the recommended package of technologies has been adopted or not by farm youth. This gives percentage of farm youth adopting the practices but not the percentage of recommended technologies adopted by them and the problems encountered by them in adopting the recommended technologies in rain fed areas.

Involvement of Farm Youth in the developmental sector of Agriculture is emerging as a crucial area for the water management sector. Initiative of Farm Youth is essential for accelerating modern Agricultural technologies to be adopted by the large number of farmers in the rural area. Being an educated, effective use of the information & communication   technology (ICT) is possible. The recent developments in the field of Agriculture like, green-house technology, exporting vegetables and fruits to outside country, formation of agricultural producer’s company etc. are the challenging areas where the Farm Youth can develop a leading role for the farming community.
 
Maharashtra, being a progressive State, encourages Farm -Youth activities in various fields to boost-up the younger generation to participate in the information and communication technology (ICT) areas. As a result of Govt. initiative, in the field of Participatory Irrigation Management, the Water Users Association, namely, ‘Mahatma Phule Water Users Association’ At Post: Ozar (Mig), Taluka: Niphad, Dist: Nasik was successfully run by a Farm Youth namely, Mr. Govardhan Rajabhau Kulkarni who is an idol for the Farm Youths to participate in the irrigation water management field. The use of internet, e-mail, agriculture related web sites and developing software programmes for irrigation management is highly appreciated by the Govt. of Maharashtra.

ICT refers to tools that facilitate production, transmission and processing of information. It includes the gadgets and processes to access, retrieve, store, organize, manipulate, produce, present and exchange information by electronic and automated means. According to UNESCO (2004), Information Communication Technology includes a range of technologies starting from radio, television, up to modern technologies like mobile phone, multimedia, internet, and satellite based communication systems. Modern information and communication technologies that have resulted from a breakthrough in information technology, when applied to conditions in rural areas, can help to disseminate information, improve farmers’ knowledge, increase their participation and share knowledge with others. Information Communication Technology (ICT) is one of the yardsticks to measure socio-economic development of the country and hence effective usage and management of ICTs tools is the pre-requisite for any development. Telephone is a powerful electronic device. The number of rural telephones was increased by approximately 35 per cent per annum (Jhunjhunwala and Ashok, 2005). This impressive growth in telecommunication sector is being utilized to provide information on demand to the farming community with the establishment of “Kissan Call Centers” (KCCs).  Kissan Call Centres were launched in January 2004 across the country to provide information services to the needy farmers and answer the queries made by them through telephone. In this context, a study was conducted to find out the profile of Kissan Call Centre users.
