Organic farming

Description

Under the organic system, the focus is on maintaining and improving the overall health of the individual farm's soil-microbe-plant-animal system (a holistic approach), which affects present and future yields. The emphasis in organic agriculture is on using inputs (including knowledge) in a way which encourages the biological processes of available nutrients and defence against pests, i.e., the resource "nature" is manipulated to encourage processes which help to raise and maintain farm productivity. The soil is a central part of that system.

Organic agriculture is best known as a method of agriculture where no synthetic fertilizers and pesticides are used.

Context

The significance of the methods promoted by organic farming enthusiasts is in how agriculture needs to consider long-range effects of farming rather than immediate returns for a healthy, sustaining economy.

Implementation

At Auroville, near Pondicherri, India, land restoration work (such as bunding, hedge plantations and water development) preceded agricultural use. Leguminous hedges were cultivated in and around agricultural lands as wind-breaks and soil builders, and for use in making compost. The agricultural practices and experiments in agriculture in Auroville are regarded as a synthesis of many different natural methods such as "French-intensive", with raised beds and dense spacing to eliminate weeds and conserve water, biodynamic, permaculture etc. Land use patterns to to be intensive and polycultural, incorporating windbreaks and hedges, fruit trees and annual or seasonal crops. Intercropping of leguminous and other plants (such as grains) and fodder trees is also practised. Fruitgrowing often tends towards a fusion of agriculture and forestry. Orchard plantations of mango, jackfruit and cashew are common as are a large variety of other tropical fruit trees such as guava, chikoo and coconut.

Rwandan farmers, faced with a perpetual land shortage, have evolved certain intensive systems of organic agriculture. These systems, particularly the homestead (compound) farming, involve the combination of food, fodder and tree crops. To a certain extent these systems can satisfy the multiple needs of the subsistence farmers living under several risks and constraints. However, they cannot cope with the expanding food demand of the rapidly increasing population. Some multipurpose, low-input technologies and agroforestry approaches have been designed to improve the productivity of these traditional systems; these include inter/mixed cropping systems and rotations, alley cropping with leguminous trees and shrubs, use of planted 'fallow,' planting tree legumes on anti-erosive lines, mixed farming, community forestry and woodlots, and tree planting on farm field boundaries.

Farming practices in California are changing. In 1984, only 4,000 acres were entirely organic, with no pesticides at all. That number was up to 70,000 by 1990, and many more are under integrated pest management.

In 1998 the amount of organically farmed land in the United Kingdom increased five-fold. The UK government's 1999 36m pounds conversion scheme to help farmers convert to organic methods ran out after four months. The Soil Association, which represents organic growers and food processors, said it would be a pity to lose out to imports when so much could be grown in the UK.

Claim

For many small farmers, natural farming is more practical. It gives the farmer greater autonomy and control. Organic farming allows small farmers to operate on a low budget, usually without external financing, and low energy input. Integrative use of trees and animals without use of fertilisers and pesticides helps replenish the soil and in raise healthier crops and animals. Components include: 'natural methods of crop rotation', inter-cropping, and manuring. For some poor soils, addition of supplementary trace elements can boost the potential of organic methods.

Organic farming is healthier for people, for the environment and for social welfare, but to make the transition from conventional farming to ecological farming normally requires a period where farm income may be substantially reduced, since certification for organic farm production generally requires at least two to three years non-use of artificial pesticides and fertilizers on the farm. Income from crops during this time of transition can be significantly less than previously.

The methodological approach used to compare organic and conventional farming systems with respect to their environmental performance is the OECD concept of environmental indicators with the following indicator categories to be subject for evaluation: Ecosystem, natural resources, farm input and output, and health and welfare. The indicator assessment shows that organic farming performs better than conventional farming with the majority of environmental indicators looked at. In no indicator category does organic farming perform worse when compared with conventional farming. To conclude, organic farming can be defined as a farming system which comprises fewer detrimental effects to the environment and to resource use than conventional farming systems and therefore currently, represents the state-of-the-art of an environmentally sensitive farming system.
