RESOURCE SYSTEM

1What is a Resource?

RESOURCE useful for human needs NATUREavailable in environment TECHNOLOGYmakes use possible ECONOMYeconomically feasible CULTUREsocially acceptable
Resource value emerges when nature, technology, economy and culture interact.

Everything available in our environment which can be used to satisfy our needs, provided it is technologically accessible, economically feasible and culturally acceptable, can be termed a resource.

NATURE TECHNOLOGY access INSTITUTIONS organisation RESOURCEhuman use + value
Core idea: Resources are not simply “free gifts of nature”. Human beings transform materials available in the environment into resources and use them.
None

3Why Resource Development Needs Planning

  • Indiscriminate use can cause depletion.
  • Resources may accumulate in a few hands, creating a divide between haves and have-nots.
  • Over-exploitation contributes to ecological crises such as global warming, ozone layer depletion, pollution and land degradation.
  • Equitable distribution is essential for sustained quality of life and global peace.

4Sustainable Development

Definition in the source: development should take place without damaging the environment, and development in the present should not compromise the needs of future generations.

Land supports ecological functions as well as economic and social activities.

Land is a natural resource of utmost importance. It supports natural vegetation, wildlife, human life, economic activities, transport and communication systems. It is finite, so it must be used with careful planning.

10Conservation Measures

  • Afforestation and proper management of grazing.
  • Shelter belts of plants.
  • Control on overgrazing.
  • Stabilisation of sand dunes using thorny bushes.
  • Proper management of wastelands.
  • Control of mining activities.
  • Treatment and proper discharge/disposal of industrial effluents and wastes.
SOIL EROSION

11Soil as a Resource — Soil Profile

SOIL FORMATION PARENT ROCKweathering CLIMATEheat + rain ORGANISMSorganic matter RELIEF + TIMEslow development SOIL PROFILEdistinct layers with different propertiessupporting plant growth and ecosystems
Soil develops gradually through the interaction of parent material, relief, climate, organisms and time.

Soil is the most important natural resource. It is the medium of plant growth and supports different types of living organisms. Soil takes millions of years to form a few centimetres in depth.

12Major Soil Types of India — Quick Visual Map

Alluvial Soil

Most widely spread; northern plains; also deltas of Mahanadi, Godavari, Krishna and Kaveri. Rich and suited to paddy, wheat, sugarcane and cereals/pulses.

Old = Bangar · New = Khadar

Black Soil

Regur; Deccan trap/Basalt region. Clayey, high moisture-holding capacity, rich in calcium carbonate, magnesium, potash and lime; ideal for cotton.

Deep cracks in hot weather → better aeration.

Red & Yellow Soil

Develops on crystalline igneous rocks in low-rainfall eastern and southern Deccan areas. Red colour is associated with iron diffusion; hydrated form appears yellow.

Laterite Soil

Develops under tropical/subtropical climate with alternate wet and dry seasons. Intense leaching due to heavy rain; generally acidic and nutrient deficient.

With conservation: tea, coffee; red laterite in parts of Tamil Nadu, Andhra Pradesh and Kerala suits cashew.

Arid Soil

Red to brown, sandy and saline; low humus and moisture. Kankar layers restrict infiltration. With proper irrigation, cultivable areas occur in western Rajasthan.

Forest Soil

Hilly/mountainous areas. Texture varies with environment; loamy/silty on valley sides and coarse on upper slopes. Lower valleys and terraces can be fertile.

14Soil Erosion — How Soil Is Lost

20NCERT Exercises — Answers

1. Multiple Choice Questions

(i) Main cause of land degradation in Punjab?

Answer: (c) Over irrigation.

(ii) State where terrace cultivation is practised?

Answer: (d) Uttarakhand.

(iii) State where black soil is predominantly found?

Answer: (b) Maharashtra.

2. About 30 words

(i) Name three states having black soil and the crop mainly grown in it.

Maharashtra, Madhya Pradesh and Chhattisgarh have extensive black soil. It is especially suitable for cotton, hence it is also called black cotton soil.

(ii) Soil in river deltas of eastern coast?

Alluvial soil. It is fertile, contains proportions of sand, silt and clay, and commonly contains potash, phosphoric acid and lime. It supports crops such as paddy, wheat and sugarcane.

(iii) Steps to control soil erosion in hilly areas?

Contour ploughing, terrace cultivation and appropriate vegetation cover can reduce the speed of runoff and restrict erosion. Terrace farming is especially useful on slopes.

3. About 120 words

(i) Explain land-use pattern in India and why forest land has not increased much since 1960–61.

Land is used for forests, land not available for cultivation, other uncultivated land, fallow land and net sown area. Its use is influenced by topography, climate and soil as well as population density, technological capability, culture and traditions. Forest area remains below the desired 33 per cent benchmark mentioned in the source. Increasing pressure from agriculture, settlements, infrastructure and economic activities, together with land degradation and other competing uses, limits expansion of forest cover. The source also notes that land-use reporting is incomplete for some areas, so the available figures do not cover the entire geographical area.

(ii) How have technical and economic development led to more consumption of resources?

Technological development increases the ability to extract, process and use resources, while economic development expands production, infrastructure, transport, industry and consumption. As technology and institutions improve, resources that were previously difficult to access may become usable. Economic growth therefore increases demand for land, minerals, energy, water and other resources. The source also warns that development without appropriate planning can produce over-exploitation, depletion and environmental problems.

Project / Activity Ideas

  • Prepare a locality-level resource consumption and conservation survey.
  • Discuss ways to conserve resources used in school.
  • Imagine the effect of exhausted oil supplies on lifestyle.
  • Solve the resource-and-soil word puzzle.
