Farming Systems and sustainability

Nature is dynamic. It causes inheritable changes in all living organisms. For thousands of years, farmer around the world have been selecting and conserving varieties of different crop Plants that they cultivated. This process has generated a rich wealth of varieties in each crop plant, seen to be most abundant in countries near the equator and India is no exception. In the world there are Mega centers of Biodiversity-2/”>Biodiversity of which aware present in India. This is because in India, the different soils and agro-climatic situations are present. So Indian farmers grow a large number of crops. Generation of Indian farmers, with their continued selection and conservation, has created a rich wealth of varieties in many crops. Therefore India is the original home of many crops such as rice, little and kodo Millets, red gram, moth bean, jute, pepper, cardamom, many vegetables and fruit species. These plants were identified from the wild, selected and cultivated by Indian farmers over hundreds of years. The present wealth of varieties in India includes both crops that originated in the country and those that were introduced from the other countries during the distant and recent paste are soybean, sunflower, oil pail and kiwi fruit.

The Indian economy is predominantly rural and agriculture oriented. In agriculture, 85% of the holdings are less than two hectares and the declining trend in the Average size of the farmer holdings, poses a serious problem. Majority of them are dry lands, which depend on erratic monsoon rains. The rest of the area is cultivated with supplemental Irrigation. The farmers concentrate mainly on crop production, which is invariably subjected to a high degree of uncertainly income and EMPLOYMENT.

In India the cultivable land is 143.8 million hectares and there is very little possibility of extending it further. Therefore, to meet the requirement of food grains for increasing Population, the only option open is through time and effective space utilization in agriculture. The time concept relates to increasing the intensity of Cropping under assured irrigated conditions, whereas space utilization pertains to building up of vertical dimension through multi-tier cropping and farming system approach. Thus by making use of these time and space concept either in irrigated or in rained areas, the productivity per unit area per unit time can be substantially enhanced. Therefore the only way to increase an agricultural production in the small/marginal units of farming is to increase is to increase the productivity per unit time and area. This may be achieved of quicker maturing varieties with equal yields or by improving techniques of culture, fertilizer use, weed and pest control.

The Green Revolution in mid sixties stirred by research based new technological developments involving new materials, models and ways of organizing farm inputs (water, fertilizer, chemical etc) and government’s policies transformed the agriculture dramatically. The outcome chewed a many fold increase in production and productivity viz. food grain production of 211 million tones ( which was only 74.23 million tones in 1966-67 ) and food grain productivity of 1697 kg/ha ( which was only 644 kg/ha in 1966-67 ). The country thus became self sufficient in food production despite tremendous pressure to sustain 16% of world human population and 10% of cattle population with just 2.4% of total land.

However modern crop production technology has considerably raised output but has residues in farm produce, gene erosion of fossil fuel based inputs such as fertilizer, pesticide, herbicides and labour spacing but energy intensive farm machinery.  Land water and plant (bio diversity) are the natural Resources and conservation of these Natural Resources is vital important. As far as resources degradation is concentrated, India is facing top Soil depletion, falling ground water table and contamination of water, ecological imbalance due to deforestation and healthy hazards linked to increase use of toxic agro- chemical because of increase in food consumption. The adverse soil loss is estimated to be over 16 tones/ha/year, which is layer of top soil. Annual top soil loss is 6000 million tones, which carries about 8.4 million tones of nutrients and it is more than what we are using today. Similarly tat energy research institute ( TERI ) reported that more than 10% of GDP is being lost annually on account of Environment and around 11-26% of country’s apicultural output is lost on account of soil degradation.

Sustainable Agriculture

In India progress in agriculture was through explitation of recourses to serve the interest of rules in the power. In the post- independence era, we were faced with the difficult task of feeding an increasing population and were burned by recurring import of food grains. Attending self- sufficient in food grain production was the challenges and a goal before Agriculture scientist. The element of strategy to achieve self- sufficiency in food production within a short time were to expand the area under cropping, make large investments in development of Water Resources, develop input supplies and market Infrastructure-2/”>INFRASTRUCTURE. Developments and promotion of high yielding varities responsive to high inputs was the cornerstone for green revolution of 1970.

We are self sufficient in food grain production. Now the question arises whether to follow the same strategies, which resulted in green revolutions or to redefine them. Consideration of our past achievement new challenges and the related development worldwide can answer this question.

  • Although we are now self sufficient in food grain production, the per capital availability has not increased significantly and a large fraction of population are still below POVERTY line due to lack of purchasing capacity.
  • At the present, Growth rate of 2 % per annum, we will be about 1.3 billion by 2025 and 1.6 billion by 2060. hence there is need to produce more from shrinking resources base.
  • Major gains in productivity and production in the past three ecades have been from areas, which had no serious limitation to production (adequate irrigation productive soils, ideal Climate etc.) productivity and production increases was moderate in eastern and central India and Deccan plateau.
  • Even in areas with no serious limitation for production, technology adopted for enhancing productivity has also simultaneous weekend the resource base resulting in a series of second – generation problems.

Modern crop production technology has considerably raised output but has created problems of land degradation pesticide residue in farm produce, gene erosion, and Atmosphere and Water Pollution. The natural resources base is degraded and diminished and the quality of the environment sustaining human life is adversely affected. Agricultural production has sustained man and great civilization. The History of the world reveals that great civilization flourished along irrigation sources and mismanagement of these resources saw the extinction of these civilizations. With expanding population and rapid depletion and degradation of the natural resource base. Sustainable agriculture has assumed very great significance. The task of meeting the needs of the present generation without eroding the ecological assets of the future generation is receiving up priority by environmental planners.

Farming Systems and Sustainability

Sustainable agriculture is a system of agriculture that focuses on producing food and fiber while protecting the environment and conserving natural resources. It is a holistic approach to agriculture that takes into account the social, economic, and environmental impacts of Farming practices.

There are many different types of sustainable agriculture, but they all share some common principles. These principles include:

There are many benefits to sustainable agriculture. It can help to improve Food Security, reduce poverty, protect the environment, and promote Economic Development. Sustainable agriculture can also help to mitigate Climate Change and build resilience to extreme weather events.

There are many challenges to sustainable agriculture. One challenge is that it can be more expensive than conventional agriculture. Another challenge is that it can be difficult to scale up sustainable agriculture practices to meet the needs of a growing population.

Despite the challenges, sustainable agriculture is a promising approach to meeting the needs of the future. It has the potential to provide food for a growing population while protecting the environment.

Here are some specific examples of sustainable agriculture practices:

These are just a few examples of the many sustainable agriculture practices that are available. By adopting sustainable agriculture practices, farmers can help to protect the environment, improve food security, and promote economic development.
