Introduction

The total geographical area for farming is 328.7 million hectares whereas, only 139.4 million hectares are a net sown area in India (NHB). India is known as an agricultural powerhouse where small and marginal farmers are at the centre of the Indian rural economy. States like Punjab and Haryana have 80% of the net sown area whereas, Arunachal Pradesh, Mizoram and Manipur have only 10% of the net sown area. With the population increasing every year, innovative farming method should be used to feed the large population, utilising vertical space to make the most limited space and time.

The most significant achievement in India after independence is the self-reliance in food grain production. The use of high yielding varieties, irrigation facilities, higher application of fertilizers & pesticides contributed to sufficient food grain production in the mid 60’s & 70’s of the last century. Later on development in other enterprises like dairy, poultry, piggery, fishery, sericulture etc., took place in an isolated manner. However, the productivity of these high yielding varieties and hybrids became stagnant during last decade and with limited scope for increasing the cultivable land, the country’s food security is likely to be threatened in the near future. According to a recent estimate the food grain requirement of India would be 380 and 450 million tons in the years 2025 & 2050 respectively with the present rate of population growth. On the other hand, despite significant breakthrough in food production the living standards of farmers are far from satisfaction; this situation is matter of great concern for the country. The farmers are losing confidence in farming due to declining returns; hence majority of them prefers to shift to non-agricultural vocations. If this trend continues in future, the potential to satisfy future food needs will be seriously compromised. Agriculture continues to be the pivotal sector in the Indian economy providing employment to 69 per cent of the population.

The coastal zone of Karnataka is marked by highly fragmented agriculture land with more than 70 per cent of the land holders belonging to small and marginal farmer categories. Though the average annual rainfall received in the zone is 4000mm, the kharif season crops suffer from submergence and lodging.  The rabi/summer crops fail due to low soil residual moisture because of high percolation loss and poor water holding capacity of soils. Thus, the returns from the land is very less resulting in migration of youngsters mainly to the Arab countries as well as the neighbouring states in search of a job. In this situation, University of Agricultural Sciences, Bangalore through Extension Education Unit, Mangalore has demonstrated the Integrated Farming Systems (IFS) in Udupi and Dakshina Kannada districts to show that the IFS is profitable, sustainable and can secure the livelihood. The demonstrations were taken up in each farmer’sfield continuously for three consecutive years.

To analyze the impact of these demonstrations, case studies of three IFS demonstrated farmers were done during 2007 with the objective of documenting the farming systems demonstrated and the current farming systems practiced by the farmers; to analyze the income and employment generated and their impact on their socio-economic status. The yearwise documentation of the subsystems of the farming systems practiced by each farmer and the net income, percent increase of income over benchmark year, employment generation, cropping intensity, B:C ratio were analyzed. The results of the case studies are presented below.

Agriculture is not only the main source of employment, income and food for over 70% of the population but also the main culture of the rural families. But the linear growth in population and unplanned colonization lead to rapid fragmentation of land holdings and shrinkage in fertile cultivated land. In India, more than 70% of the total population of the country still live in villages and mainly depend on agriculture and/or related enterprises. Marginal and small farmers constitute more than 84% of the 115 million operational holdings in India which are cultivating only 29% of the arable land (Singh et al., 2011). 

Abstract

The green revolution concentrated only on a single enterprise, the crop.  Later on, developments in other enterprises like dairy, poultry, piggery, fishery, etc took place, however in an isolated manner.  Now it is essential to diversify the economic activities in an interdependent and integrated manner at micro level within the available resources. The system thus developed will be termed as integrated farming system approach.  This helps in generating sustained, stable farm income and higher employment. To achieve these objectives, several extension programmers were designed and conducted in integrated farming system demonstration undertaken by the Extension Education Unit of University of Agricultural Sciences, Bangalore in close association with other subject matter specialists. The programmes were implemented in selected taluks of Eastern Dry Zone of Karnataka. One such case study is presented here.

India is predominately a agriculture based country, wherein 85 per cent of the land holding are small and marginal. The per capita availability of land has been decreased from 0.5 ha in 1950-51 to 0.15 ha by the turn of the century and a projected future decline to less than 0.1 ha by 2020. This decline in trend in size of land holding poses a serious challenge to sustainability and profitability of the farming. The population is steadily growing without any possibility of increase in land area. The income from cropenterprise for an a average farmer is hardly sufficient to sustain his family. But the farmer has assured of a regular income for a reasonable standard of living by including other enterprises. The integrated farming system (IFS) seems to be the solution to continue to increase the demand for food production, stability of income and improvement of nutritional status of family members.
 
Agriculture in this millennium, due to emerging production scenario, higher economic growth, population explosion and shifts in dietary pattern has changed the supply and demand profiles of food respectively. Integrated Farming Systems (IFS) seems to be the possible solution to meet the continuous increase in demand for food, stability of income and diverse requirements of food grains, vegetables, milk, egg, meat etc., thereby improving the nutrition of the small-scale farmers with limited resources.

Introduction

Farming system that advised integrated the needs of the ancestors the economic factors like profitability, amusing acceptability and economically active and technically achievable enterprises in a accumulated furnishings wherein availability of acreage resources, basement and institutions such as irrigation, marketing facility business accessories including storage and transportation and credit besides the agro biological application namely interdependence. Technically achievable enterprises and the achievement of individual farmers are to be advised as above factors in farming system approach. Farming system, therefore, designates a set of agronomical activities organized while attention acreage productivity, anatomy superior and advancement adorable similar of biological assortment and ecological stability. The accent is added on a system rather than on gross output. In added words farming system is an ability administration action to accomplish bread-and-butter and sustain agronomical accumulation to be accommodated a sorted claim of the acreage domiciliary while attention the ability and advancement top quality. Farming system in its absolute faculty will advise the afterward agency to lift the abridgement of Indian farming and accepted of active of the farmers. Farming system distinctively refers to an accumulation aggregate of enterprises in which the articles and or the byproducts of one action serve as the inputs for accumulation of added enterprise. Farming systems access has appear after than that farming came into actuality getting strategically activated as breadth specific suitability. Farming systems decidedly contributed to the re-silence of farming and as able-bodied as affluence farming, organic farming and inorganic farming. Agro-climatic regions of the country are abounding adapted and differed from breadth to breadth wherein types of farming are as well different. Somewhere, the farming is based on horticulture, ley farming, agroforestry and abounding added like farming of agronomic crops. India’s bounded locations are amenable for such variations, as the assertive locations acquaintance altered climates, appropriately affecting anniversary region’s agronomical abundance differently. India is actual abased on its vagaries of cloud burst abundantly to accord satisfactory crop yields. India’s farming has all-encompassing accomplishments which go aback to at organic 10 thousand years. Reportedly, the country holds the additional position currently in agronomical accumulation in the world. In 2007, farming and affiliated industries fabricated up added than 16% of India’s GDP. Despite the abiding abatement in agriculture’s addition to the country’s GDP, now the farming is getting advised as the bigger activities antecedent of alimentation in the country and plays a key role in the socio-economic advance of the country. Now a day, India is the additional bigger ambassador of wheat, rice, cotton, sugarcane, silk, groundnuts, and of abounding more. It is as well the bigger farming of vegetables and fruit, apery 8.6% and 10.9% of all-embracing production, respectively. The above fruits produced are mangoes, papayas, sapota, and bananas. India as well has the bigger amount of livestock in the world, captivation 281 million. The country housed the additional bigger amount of animals in the tune with 175 million in the year 2008. In this accomplishments the apperception of farming system, appropriately was demography application as aggregate of agri-horti and animals, veterinary including fisheries taken into account as integrated approach.

Abstract
Integrated Farming Systems (IFS) represent a holistic and sustainable approach to agriculture that seeks to maximize resource efficiency, environmental conservation and economic viability by integrating various agricultural enterprises within a farm. The concept hinges on the synergistic interactions between crops, livestock, aquaculture, agroforestry and other components, ensuring that waste from one system serves as input for another, thus minimizing resource wastage and enhancing productivity. IFS promote diversification, reducing dependency on a single crop or product and thereby mitigating risks associated with market and climate fluctuations. By incorporating livestock and aquaculture, IFS enhance nutrient cycling and soil fertility through the recycling of organic matter and manure. Agroforestry practices within IFS contribute to soil conservation, water management, and biodiversity enhancement, creating a resilient agricultural ecosystem. The economic benefits of IFS are notable, with diversified income streams providing financial stability to farmers. The reduced need for chemical fertilizers and pesticides, owing to natural nutrient cycling and pest control, also contributes to cost savings and environmental health. Additionally, IFS support food security by producing a variety of food products, from grains and vegetables to meat and fish, on the same farm. The successful implementation of IFS requires careful planning and knowledge integration, ensuring that the various components harmonize and contribute positively to the overall system. Despite challenges such as initial investment costs and the need for technical expertise, IFS offer a viable pathway towards sustainable agriculture, balancing productivity with ecological and economic sustainability.

Introduction

Agriculture occupies a prominent place in Indian economy and rural livelihoods. But, it is faced with the challenge of producing food for a rapidly growing population whilst maintaining the nation’s fragile resources.Efforts through green revolution brought out significant increase in food grain production by concentrating on the potential farms in terms of irrigation and other basic resources.Nationally and globally, it is necessary that the growth rate of food production must remain higher than the population growth rate to avoid hunger and overcome famines. But, food security one of the basic human rights is in jeopardy, today. Agriculture is crucial for ensuring the food and livelihood security of the country and hence it is important that this sector with diversified farming systems becomes resilient to increasing climatic variabilities and global economic changes. This concept encourages the farmers towards efficient utilization of natural resources and also proper channelization of by-products of one enterprise to the other enterprise in farming. The integrated farming systems, therefore, assume prime place for sound management of farm resources to enhance the farm productivity, reduce the environmental degradation, and improve the quality of life of resource poor farmers and to maintain the sustainability to meet the challenges of food security. In order to meet the soaring demand for food there is a need to go for integrated faming system.This approach facilitates in strengthening the socio-economic status of Indian farmers besides strengthening ecological balance. Integrated farming system is common to Indian farmers simply because of the preponderance of small farm systems which form the backbone of traditional agriculture. For small farmers, these systems enable a means of diversifying the use of meagre resources in the context of a rational means of reducing risk. Additionally, it also enables increased efficiency in the use of these same resources in a manner that there will be livelihood security and stability to farming systems. There is no scope for increasing the farm size. Yet steady increase in population with shrinkage of cultivated land as a result of industrialization and urbanization would pose serious hurdle for agricultural development. Only vertical expansion is possible by integrating appropriate farming components requiring lesser space and time ensuring continuous income to the farmers.

Integrated farming system is a multidisciplinary whole farm approach, which enables the farmers to identify opportunities and threats and act accordingly. It
is a dynamic approach which can be applied to any farming system around the world. It is very effective in solving the problems of small and marginal farmers.
The approach aims at increasing income and employment from small-holding by integrating various farm enterprises and recycling crop residues and by-products
within the farm itself.

Introduction

Decision making is the most important aspect of any business and industry. Farming is a business and agriculture is also an industry. Hence, decision making plays an important role with regard to the problems concerning production of commodities. The main questions before the producer or the production manager are: (i) What to produce, (ii) How to produce, and (iii) How much to produce.

Linear programming (LP) is a modeling tool that can assist in the solution of many problems in agriculture. It is useful in selecting the best alternative from a number of available course of actions.

LP models are designed to “optimize” a specific objective criterion subject to a set of constraints. The quality of the resulting solution depends on the completeness of the model in representing the real system.

What is a system?

A group of interacting components, operating together for a common purpose, capable of reacting as a whole to external stimuli is called a system. It is not affected directly by its own outputs, having a specified boundary based on inclusion of all significant feedbacks. Human body is a system with a boundary (e.g., the skin) enclosing a number of components (heart, lungs) that interact (the heart pumps blood to the lungs) for a common purpose (to maintain and operate the living body). Collection of unrelated items does not constitute a system. A bag of pebbles is not a system because with addition or removal of a pebble, a bag of pebbles remains and is almost not affected completely by that change. Pebbles behave as a whole if the whole bag is influenced, for example by dropping it; the constituent parts go their own ways with its bursting. It is the property of the system that mainly matters and it may be summarized in the phrase ‘behaviour as a whole in response to stimuli to any portion’.

The vulnerability of agriculture to climate change has become an important issue resulting in reduced productivity due to adverse climatic changes. The overall purpose is to assess farming systems change to enable adaptation to climate change. It deals with the predicted climate change scenarios and the adaptations necessary to reduce climate change impacts and examines improvement of indigenous breeds for adaptation to climate change. It also explores the use of crop modeling as avenues to address adaptations of crop production systems and draws the recommendations to outlines of future research needs.

Although the adverse effects of climate change are likely to be borne disproportionately by the small farmers of the developing world, it is the integrated farming systems with their high degree of biodiversity which are best equipped to withstand the shocks of climatic extremes. Apart from the landless and urban poor, small farmers are among the most disadvantaged and vulnerable groups in the developing world. It is obvious that climate-related environmental stresses are likely to affect individual households differently compared to more market-oriented farmers. The climate change reduces crop yields. The effects on the welfare of subsistence farming families may be quite severe, especially if the subsistence component of productivity is reduced. Changes in quality and quantity of production may affect the labour productivity of the farmer and negatively influence his/her family health(Rosenzweig and Hillel 1998).

Introduction

Agriculture is a dynamic sector affected by rapid changes in environment and climate, technologies, development priorities, impact of changes in other sectors and social changes such as family structure, migration and international policies such as globalization and liberation. The Indian Green Revolution of the 1960s and 1970s, with its package of improved seeds, farm technology, better irrigation and chemical fertilizers, was highly successful in meeting its primary objective of increasing crop yields and augmenting food supply. However, the Green Revolution as a development approach has not necessarily translated into benefits for the lower socioeconomic strata, particularly the rural poor and farm women, in terms of greater food security or greater economic opportunity. It has increased the need for cash incomes in rural households to cover the costs of technological inputs which has forced women to work as agricultural laborers and increased the need for unpaid female labor for farming tasks.

In the era of burgeoning population and shrinking natural resources integrated farming system may be the panacea. Integrated Farming system approach envisages the integration of agroforestry, horticulture, dairy, sheep and goat rearing, fishery, poultry, pigeon, biogas, mushroom, sericulture and by-product utilization of crops with the main goal of increasing the income and standard of living of small and marginal farmers. Integrated systems are about bringing crops and livestock into an interactive relationship with the expectation that together, as opposed to alone, they will generate positive effects on outcomes of interest, such as profitability overall productivity and conservation of nonrenewable resources. It is, however, much more than this. The “system” includes the environment, soil characteristics, landscape positions, genetics and ecology of plant and animals. It involves management practices, goals and lifestyles of humans, social constraints, economic opportunities, marketing strategies and externalities including energy supplies and costs and impacts of farm policies. Systems also reflect available natural resources and the impact on their use, wildlife issues, target and non-target plant and animal species, micro-organisms and indeed all of the definable and indefinable factors that ultimately interact to result in an outcome that is never constant. The aims of integrated farming system is to increase productivity, profitability, sustainability, balanced food, clean environment, recycling of available resources and income round the year. Besides we can also think for adoption of new technology, solving energy crises: fuel and fodder crises, avoiding deforestation, increasing employment generation by taking more than one component, input-output efficiency and enhancing opportunity for agriculture oriented industries as well as uplifting living standard of the farmers

Introduction

It is obvious beyond doubt that the climate is changing. Climate has also been changing in the past, but its rate of change has been unprecedented in recent past years. It is true that no one could stop the climate from changing, but could do a lot for mitigating some of its effects and formulate adaptation mechanisms to it. Agriculture, especially the small holder producers have been at the receiving end of the climate change effects, resulting into not only in the fluctuating and unstable productivity, loss of natural resources and consequent livelihoods, but also to their survival.

Climate change and food insecurity are two most pressing challenges human beings are facing today and has emerged as the biggest twin challenge of this century. There are evidences that the increase in greenhouse gases caused by human activities is responsible for global warming and consequent climate change (FAO, 2007). Under the six emissions scenarios the global average surface temperatures are expected to increase by 1.1°C - 6.4°C this century [IPCC, 2007]. Climate change has its impact on almost everything on the earth and so on the food production. The agriculture plays a very important role in the economy of most of the nations of the developing world. For India, agriculture is the base of nation’s economy, largely rainfed and dominated by smallholders (Singh 2008 and 2010). As per reports from a number of governments, non-government and intergovernmental organizations, the countries and agriculture especially practiced by smallholders are particularly vulnerable to climatic changes and they have least capacity to adapt to these changes. In most of the developing countries of the world, the agriculture is not merely a matter of cultural practice but it is the source of livelihoods of millions of smallholders and their dependents. Changing climate as predicted will not only affect the agricultural productivity but also heavily hit the lives and livelihoods of the smallholder families and ultimately lead to food insecurity to the concerned nation and the world (Singh et al. 2012). Business-as-usual scenarios of population growth and food consumption patterns indicate that agricultural production will need to increase by 70 percent by 2050 to meet global demand for food. South-Asian countries made tremendous progress in food production in 1960s, 1970s and 1980s. with an impressive growth of food production, India, Pakistan, Bangladesh and Nepal transformed themselves from countries with a chronic food deficit to countries that were almost self sufficient in early 1990s. Except Afghanistan, all these countries had exported some quantities of food grain in late 1990s. The dynamic growth in the agriculture sector has, however, recently been lost. Productivity of major food grains has slowed and has been decline for some crops (Kumar et al. 2008) with food production failing to keep pace with population growth (G. Rasul and A. Schild 2009). As a result, South-Asian countries are now finding it difficult to meet their population most basic food and nutritional needs and remain vulnerable to food insecurity (Tab.1).

Integrated farming system is a multidisciplinary whole farm approach, which enables the farmers to identify opportunities and threats and act accordingly. It is a dynamic approach which can be applied to any farming system around the world. It is very effective in solving the problems of small and marginal farmers.

Introduction

The development of software in the sphere of information technology and agriculture currently make up the majority of the economy (Shashank et al., 2006). The majority of people in our country live in rural areas, so efforts to improve the economy must be concentrated there. To make any kind of progress in rural areas, strategies should be developed that will primarily focus on some crucial points, including the sustainable use of natural resources and their conservation, increasing production and profitability by efficiently using the resources already available, and improving quality and productivity by reducing waste.

Pulse crops have a unique position in sustainable crop production as they provide proteinaceous food of high nutritive value and keep the soil alive and productive. India is the largest producer and consumer of pulses in the world which accounts for 32 per cent of global area and 28 per cent of world’s pulse production. But the yield levels of these pulse crops are not satisfactory as it is grown as a neglected crop. Besides, extensive damage caused by insect pests is another major constraint for low yield of pulse crops. On an average annually 2.5 to 3.0 million tonnes of pulses are lost (Rabindra et al., 2004) with a monetary value of nearly Rs.6,000 crores due to ravages of insect pest complex (Reddy, 2009 and Panda et al. 1998). About 250 insects have been recorded feeding on these pulse crops in different parts of India (Narang, 1990) of which maximum damage is caused by the pod borer complex along with some sucking pests and foliage feeders. Sap feeders viz., aphids, whitefly, leaf hopper, thrips ; defoliator viz., leaf roller, hairy caterpillars etc are major threats to the crop during vegetative stage whereas the pod borers and pod sucking bugs are of major concern during reproductive stage. About two dozen insect pests are very important and found occurring on one or the other pulse crop frequently causing variable degrees of damage. A list of the very common insect and mite pests infesting different pulse crops (Table 1) and the extent of loss caused by different insect pests to some important pulse crops documented by the IIPR, Kanpur (Table 2) are furnished below.
