Types and classification of وسائل
Resources may be classified by origin (biotic/abiotic), exhaustibility (renewable/non-renewable), ownership (individual, community, national, international) and status of ترقی (potential, developed, stock and reserves).
وسائل کی منصوبہ بندی in ہندوستان
وسائل کی منصوبہ بندی involves identifying and inventorying وسائل, developing appropriate technology and institutional arrangements, and matching resource ترقی with national priorities. It is اہم because وسائل are unevenly distributed.
Land وسائل and land use
Land supports زراعت, forests, settlements, transport and صنعت. Land-use patterns reflect physical factors as well as population, technology and economic activities.
Land degradation
Deforestation, overgrazing, mining, over-irrigation and industrial waste can degrade land. Afforestation, controlled grazing, proper irrigation, reclamation and regulated industrial activity help reduce degradation.
Soil as a resource
Soil formation depends on relief, parent rock, climate, vegetation, organisms and time. Major ہندوستانn soil groups include alluvial, black, red and yellow, laterite, arid and forest/mountain soils.
Soil erosion and تحفظ
Water and wind can remove fertile topsoil. Contour ploughing, terrace farming, strip cropping, shelter belts, afforestation and careful land management help control erosion.
Sustainable ترقی
Development must meet present needs while conserving the resource base for future generations. Conservation is therefore linked with both economic ترقی and environmental security.
