Natural resource inventory of Manbazar block (Purulia district) in the eastern plateau of India: Technology intervention for sustainable agricultural development

چکیده
Natural resource base degradation, forest denudation, instability in crop production due to scarcity of water necessitates a thorough insight on sustainable agricultural development for conservation of natural resources not only for the present generation but also for the posterity. An attempt had been made to study the natural resource inventory of part of eastern plateau of India, using LISS III satellite imagery and Participatory Rural Appraisal Technique (procedure for rapid acquisition of sufficient knowledge with the involvement of rural people and household survey for development activity and decision making). Topo-sequence based micro-level study revealed that there were four types of land situations: upper terraces locally called Tanr, Bahri (land close to homesteads), Baad (middle terraces) and Garha (lower terraces). Adverse biophysical and socioeconomic conditions and age-old, traditional, unscientific agricultural activities in the region act as deterrents for crop production and natural resource management. Based on the study, it can be concluded that priority should be given to long term strategies encompassing: construction of water harvesting structure of different sizes for different land situations; silviculture or silvi-pastoral system (cultivation of trees and pasture simultaneously) on upland; cultivation of short duration flash flood tolerant high yielding rice variety for Aman (wet) season, and cold tolerant rice variety for winter season in low land areas; social forestry in degraded land; agro-ecologically suited cropping systems with suitable variety choice for problem areas; and judicious nutrient management in homestead gardens which may be ecologically suitable, socio-economically acceptable, technologically sound, and environmentally sustainable for future perspective.

The issue of convergence or divergence of productivity has important policy for regional poverty reduction and increasing standards of living. If productivity converges to a common level without intervention, there is little need for explicit policies in lagging regions to promote catch up. On the other hand, productivity has divergence trend, then explicit policies would be needed to prevent f...
