Chapter Overview
Resources are materials, objects, forces and conditions that can satisfy human needs when they are technologically accessible, economically feasible and culturally acceptable. The chapter connects resource classification with planning, conservation and sustainable development.
Detailed Textbook-Aligned Concepts
Types and classification of resources
Resources may be classified by origin (biotic/abiotic), exhaustibility (renewable/non-renewable), ownership (individual, community, national, international) and status of development (potential, developed, stock and reserves).
Resource planning in India
Resource planning involves identifying and inventorying resources, developing appropriate technology and institutional arrangements, and matching resource development with national priorities. It is important because resources are unevenly distributed.
Land resources and land use
Land supports agriculture, forests, settlements, transport and industry. 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 Indian soil groups include alluvial, black, red and yellow, laterite, arid and forest/mountain soils.
Soil erosion and conservation
Water and wind can remove fertile topsoil. Contour ploughing, terrace farming, strip cropping, shelter belts, afforestation and careful land management help control erosion.
Sustainable development
Development must meet present needs while conserving the resource base for future generations. Conservation is therefore linked with both economic development and environmental security.
