Resources and Development: Classification, Conservation, and Sustainable Development

This chapter in CBSE Class 10 Geography introduces the concept of resources — everything available in the environment that satisfies human needs and is technologically accessible, economically feasible, and culturally acceptable. Resources form the basis of all economic activity and human well-being, yet they are limited on our planet. This chapter classifies resources based on origin (biotic vs. abiotic), exhaustibility (renewable vs. non-renewable), ownership (individual, community, national, international), and status of development (potential, developed, stock, reserves). It also discusses sustainable development, resource planning in India, and the conservation of land and soil resources.

Resources are classified by origin as biotic (obtained from the biosphere, having life — forests, wildlife, fisheries, livestock, crops) and abiotic (non-living — land, water, minerals, fossil fuels). By exhaustibility: renewable resources can be replenished naturally over time (solar energy, wind, water, forests), though overuse can degrade them, while non-renewable resources form over geological timescales and cannot be replenished once exhausted (coal, petroleum, natural gas, minerals). The rate of consumption of non-renewable resources is far exceeding the rate of their formation. By ownership: individual resources (privately owned — agricultural land, house, car), community resources (accessible to all members of a community — grazing lands, village ponds, burial grounds), national resources (belonging to the nation — all minerals, forests, water within territorial boundaries), and international resources (beyond territorial waters — oceanic resources in the High Seas regulated by international law). By status of development: potential resources (available but not yet utilised — solar energy in Rajasthan, wind energy in Gujarat), developed resources (surveyed and quantified with technology for exploitation — the Damodar coal fields), stock (materials that have the potential to satisfy needs but human technology is inadequate to access them — hydrogen as fuel, or gold dissolved in seawater), and reserves (a subset of stock that can be used with existing technology but is being held back for future use — water in dams, forest reserves).

Resource planning is essential for balancing development with conservation. India has a vast diversity of resources — Jammu and Kashmir has high potential for hydroelectricity and horticulture but lacks transport infrastructure; Arunachal Pradesh has abundant water but limited industrial development; Rajasthan has huge solar and wind energy potential that remains untapped. Resource planning involves three stages: (1) identification and inventory of resources — surveying, mapping, quantitative estimation (using satellite remote sensing, GIS, and ground surveys). (2) Evolving a planning structure with appropriate technology, institutional arrangements, and human skills. (3) Matching resource development plans with national development goals. Sustainable development means development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs, as defined by the Brundtland Commission (1987). Land degradation — the decline in the quality of land making it unfit for agriculture — is a major concern caused by deforestation, overgrazing, over-irrigation (leading to waterlogging and salinity), mining (leaving deep scars and dumping waste), and industrial effluents. Soil conservation methods include: contour ploughing (ploughing along contour lines to slow water runoff), terrace farming (cutting steps on slopes, used in hilly areas like Uttarakhand), strip cropping (alternating strips of different crops), shelterbelts (lines of trees planted to prevent wind erosion in desert areas like Rajasthan), and afforestation (planting trees). Landslides in the Himalayas are caused by a combination of natural factors (steep slopes, earthquakes, heavy rain) and human factors (deforestation, road construction, mining). The chapter also introduces the concepts of resource ethics (reduce, reuse, recycle) and the Rio Summit (Earth Summit, 1992) where the international community agreed on Agenda 21 for sustainable development.

• Resources classified by: origin (biotic/abiotic), exhaustibility (renewable/non-renewable), ownership (individual/community/national/international), development status (potential/developed/stock/reserves).
• Resource planning: identify resources (surveying → mapping → quantification), develop appropriate technology, and align with national development goals.
• Sustainable development: meeting present needs without compromising future generations' ability to meet theirs (Brundtland Commission, 1987).
• Land degradation causes: deforestation, overgrazing, over-irrigation (salinity), mining, industrial waste. Conservation: contour ploughing, terrace farming, shelterbelts, afforestation.
• Reduce, reuse, recycle (3Rs); Rio Summit (1992) produced Agenda 21 for global sustainable development.
