ORGANIC FARMING FOR CROP IMPROVEMENT AND SUSTAINABLE AGRICULTURE IN THE ERA OF CLIMATE CHANGE

Abstract

Sustainable development has caught the imagination and action of the world for more than a decade. Sustainable agriculture is necessary to attain the goal of sustainable development. According to the Food and Agriculture Organization (FAO), sustainable agriculture is the successful management of resources to satisfy the changing human needs while maintaining or enhancing the quality of environment and conserving natural resources. All definitions of sustainable agriculture lay great emphasis on maintaining an agricultural growth rate, which can meet the demand for food of all living beings without draining the basic resources towards crop improvement. Organic farming is one of the several approaches found to meet the objectives of sustainable agriculture. Most of the techniques used in organic farming like inter-cropping, mulching and integration of crops and livestock are not alien to agriculture systems including the traditional agricultural practices. However, organic farming is based on various laws and certification programmes, which prohibit the use of almost all synthetic inputs and the central theme of this method is the health of soil. The adverse effects of modern agricultural practices on the farm and also on the health of living beings and thus on the environment has been well documented all over the world. Application of technology, particularly the use of chemical fertilizers and pesticides all around us has persuaded people to think aloud. As a result of global climatic changes, their negative effects on the environment are manifested through soil erosion, water shortages, salination, soil contamination, genetic erosion, Organic farming is one of the widely used methods, which is thought as the best alternative to avoid the ill effects of chemical farming. It also has far more advantages over the conventional and other modern agricultural practices that are available today.
