DESERTIFICATION, LAND DEGRADATION AND VULNERABILITY ASSESSMENT THROUGH BIOTECHNOLOGY: A CASE STUDY OF RAJASTHAN STATE OF INDIA
Desertification is a human and social problem which is not susceptible to quick solutions, but is already urgent in arid, semi-arid and sub-humid dryland regions, Desertification commonly appears as degradation of plant, animal, soil and water resources and general loss of biological productivity in areas under ecological stress. In fragile ecosystems, degradation can easily become irreversible and permanently reduce the capacity of the areas affected to support human life
Bio-technology has most important role in effective mitigation of desertification and all degraded lands are possible to be treated through these devices. Application of bio-technology in the field of agriculture relates mainly to improvement in production and productivity. Food and nutrition situation depend on land, water and, energy resources which are generally limited. The biotechnology addresses researches aimed at increasing production, higher nutritional value, and greater plant resistance to adverse weather conditions, pathogenic agents and pests. The contribution of plant genetics in recent discoveries in molecular biology and exploitation of certain characters peculiar to plant. The paper highlights the Indicators of Desertification, Degree and Extent of Desertification, Process and Causes of Desertification, Biotechnology for Combating Desertification, Biotechnology and Mitigation Measure for Desertification, Mitigation Technologies and Approaches, Studies of Agro-Ecological Regions and Strategy and Planning for Combating Desertification
