Natural Resources: Classification, Planning and Sustainable Use

1. When nature becomes a resource

Read the detailed note →

• Nature (Class 8): all living and non-living things that humans did not make. Part of nature becomes a resource when people use it. A tree becomes a resource when its wood is made into furniture.
• Resource (Class 10): anything in our surroundings that can meet our needs, if it is:
• technologically accessible: we have the tools to reach it (oil deep under the sea may be out of reach);
• economically feasible: it is worth the cost of taking it out;

• culturally acceptable: people accept its use (trees in sacred groves are not cut).

• Natural resource: a material or substance in nature that is valuable to humans. Even a plastic button traces back to nature.

• Resources are not free gifts of nature. They come from human activity, through the link between nature, technology and institutions (Class 10, Fig. 1.1). Humans are themselves resources.
• Beyond NCERT: Erich Zimmermann (1933) said "resources are not, they become." Uranium and lithium became resources only when new technology found a use for them.
• Classification by use (Class 8): resources for life (air, water, food from soil), for materials (wood to marble, coal to gold) and for energy (coal, water, petroleum, gas, sun, wind).

2. Classifying resources by origin and exhaustibility

Read the detailed note →

• Class 10 (Fig. 1.2) classifies resources on four bases: origin, exhaustibility, ownership and status of development.

Basis	Classes	Examples
Origin	Biotic resource (from the biosphere, has life)	humans, flora, fauna, fisheries, livestock
	Abiotic resource (non-living)	rocks, metals, minerals, water, air
Exhaustibility	Renewable resource (can be renewed by physical, chemical or mechanical processes)	flow resources: wind, water; biological resources: forests, wildlife
	Non-renewable resource (formed over long geological time)	minerals, fossil fuels

• Trap: coal and petroleum come from living things but are abiotic, because they are no longer alive.
• Non-renewables are either recyclable (metals) or used up once used (fossil fuels that are burnt).
• Class 8: a resource stays renewable only if we use it more slowly than nature restores it (heals it) and regenerates it (makes new life). Examples of overuse: timber cut faster than trees regrow, Himalayan glaciers (the "water tower") melting faster than snow and rain replace them, and overfishing of tuna.
• Ecosystem services: nature's work that benefits people, such as forests filtering water. A mature tree gives about 275 litres of oxygen a day; a person needs about 350 litres (Class 8).
• Class 8 says India's coal may last about 50 years (dated; verify current).

3. Ownership and status of development; the commons

Read the detailed note →

• By ownership (Class 10):
• Individual: farms, houses, wells.
• Community-owned resource: open to every member of a community. Examples: grazing grounds, burial grounds, village ponds, parks.
• National: minerals, water, forests, wildlife, and the sea up to 12 nautical miles (territorial waters).

• International resource: run by international bodies. Example: the ocean beyond 200 nautical miles (past the Exclusive Economic Zone), which no country can use without bodies like the International Seabed Authority (Kingston, Jamaica; set up in 1994 under UNCLOS 1982). India holds ISA contracts to explore for polymetallic nodules in the Central Indian Ocean Basin.

• By status of development:

• Potential resource: found but not yet used, e.g. solar and wind in Rajasthan and Gujarat.
• Developed resource: surveyed, with its quality and quantity known, e.g. coal and iron ore being mined.
• Stock: could meet needs, but we lack the technology to use it, e.g. energy from hydrogen in water. The National Green Hydrogen Mission (2023) is now moving hydrogen out of stock.

• Reserves: the part of the stock we can use with today's know-how but keep for later, e.g. water in dams.

• Tragedy of the commons (Garrett Hardin, 1968): when anyone can use a shared resource (pasture, fishery, aquifer), each user gains from using more while everyone shares the cost, so the resource gets overused. Elinor Ostrom (1990; Nobel 2009) showed that communities with clear rules manage commons well. Indian examples: van panchayats in Uttarakhand and orans in Rajasthan. India's biggest commons problem is groundwater.

4. Uneven distribution of resources and the natural resource curse

Read the detailed note →

• Resources are spread unevenly across the world and within countries (Class 8). This shapes where people settle, trade, relations between countries and wars.
• Mines and industries near resources bring jobs and townships, but they also displace people and threaten sacred places.
• Rivers cross state and national borders, so sharing them causes disputes. Examples: the Kaveri shared by Karnataka, Tamil Nadu, Kerala and Puducherry (Mettur dam is in Tamil Nadu), and the Brahmaputra shared between countries.
• India's pattern (Class 10):
• Jharkhand, Chhattisgarh and Madhya Pradesh are rich in minerals and coal.
• Arunachal Pradesh has plenty of water but little infrastructure.
• Rajasthan has solar and wind energy but little water.

• Ladakh has rich heritage but lacks water, infrastructure and minerals.

• Natural resource curse, or "paradox of plenty": some resource-rich places grow more slowly. Reasons:

• they export raw materials without building industries that add value;

• "Dutch disease" (a stronger currency hurts other exports), swings in prices, weak governance and conflict (Congo, Nigeria).

• Norway and Botswana avoided the curse. Class 8 says India did too, by building industries. Even so, the mineral belt of Jharkhand, Odisha and Chhattisgarh stays poor. One response is District Mineral Foundations (set up under the MMDR Amendment 2015), which use mining money for the welfare of mining areas.

5. Limits to growth: problems of indiscriminate use and how we measure overuse

Read the detailed note →

• Three problems of overusing resources (Class 10):
• resources are used up to satisfy the greed of a few;
• resources pile up in a few hands, splitting society into haves and have-nots;

• global ecological crises follow: global warming, ozone depletion, pollution and land degradation.

• The Population Bomb (Paul Ehrlich, 1968) warned that fast population growth would cause mass famine.

• Club of Rome: a think tank founded in 1968. Class 10 credits it with being the first to argue for resource conservation in a systematic way.
• The Limits to Growth (1972; Donella Meadows and others): its computer models warned that unchecked growth in population, industry and resource use would hit the planet's limits within a century. Critics say the Green Revolution proved the famine forecasts wrong.
• Ecological footprint: the land and water area (in global hectares) needed to supply what we use and absorb our waste. Humanity uses about 1.7 Earths (verify current).
• Earth Overshoot Day: the day each year when human demand goes beyond what the Earth can renew in that year. In 2025 it fell on 24 July (verify current).
• Planetary boundaries (Johan Rockstrom and others, 2009): nine safe limits for the Earth system, including climate change, biosphere integrity, freshwater, nitrogen and phosphorus flows, ocean acidification and novel entities. The 2025 Planetary Health Check found seven crossed (verify current).

6. Conservation thought and sustainable development: from Gandhi to Brundtland

Read the detailed note →

• Gandhian view of resource conservation: "There is enough for everybody's need and not for anybody's greed." Gandhi blamed greedy people and exploitative modern technology. He wanted production by the masses instead of mass production.
• Small is Beautiful (E.F. Schumacher; NCERT: 1974; first published 1973) restated Gandhian ideas. It argued for small-scale technology that serves people.
• Class 8 adds Indian ideas: lokasangraha (from the Bhagavad Gita: act for the wellbeing of all) and Vrikshayurveda (Surapala, about 10th century CE), an old science of caring for plants.
• Stockholm Conference 1972 (5-16 June): the first big UN meeting on the environment.
• It created UNEP (headquarters Nairobi) and made 5 June World Environment Day.

• Indira Gandhi said poverty and need are the greatest polluters.

• Brundtland Commission Report: the UN World Commission on Environment and Development, chaired by Norway's Prime Minister Gro Harlem Brundtland, published Our Common Future in 1987.

• Sustainable development: "development that meets the needs of the present without compromising the ability of future generations to meet their own needs." It balances three sides: ecological, social and economic.

7. Rio 1992, Agenda 21 and the Sustainable Development Goals

Read the detailed note →

• Rio de Janeiro Earth Summit (UN Conference on Environment and Development, UNCED), Brazil, 3-14 June 1992. More than 100 heads of state attended.
• What Rio produced:
• the Rio Declaration (27 principles, including common but differentiated responsibilities, the precautionary principle and polluter pays);
• Agenda 21;
• the non-binding Forest Principles;

• the UNFCCC and the CBD, opened for signature. India and 155 other nations signed the CBD at Rio (Class 11).

• Trap: Class 10 calls the climate and biodiversity texts a "Declaration on Global Climatic Change and Biological Diversity". Their correct names are the UNFCCC and the CBD. The UNCCD (on desertification) came later, in 1994.

• Agenda 21: a non-binding action plan for sustainable development in the 21st century. It fights environmental damage, poverty and disease through global cooperation. A key aim is that every local government draws up its own Local Agenda 21.
• Follow-ups: Johannesburg (2002) and Rio+20 (2012, "The Future We Want"), which started the SDG process.
• Sustainable Development Goals: adopted on 25 September 2015 in the UN 2030 Agenda, with 17 goals and 169 targets for 2030. They replaced the 8 Millennium Development Goals and apply to every country. Goals with a geography angle: SDG 6 (water), 13 (climate), 14 (life below water) and 15 (life on land).
• NITI Aayog publishes the SDG India Index (since 2018). Kerala has usually come first (verify current).

8. Resource planning in India

Read the detailed note →

• Resource planning is the plan for using resources wisely. India needs it because resources are spread so unevenly. Planning must happen at national, state, regional and local levels.

• Three steps (Class 10): 1. Identify and inventory resources by surveying, mapping, and estimating their quality and quantity. 2. Build a planning structure with the right technology, skills and institutions to carry out resource plans. 3. Match resource development plans with national development plans.

• India has worked on these goals since the First Five Year Plan (1951).

• Inventory agencies (beyond NCERT): Survey of India (1767), Geological Survey of India (1851), Indian Bureau of Mines (1948), Forest Survey of India (1981), Central Ground Water Board, and NRSC/ISRO (satellite maps of land use).
• Planning structure: the Planning Commission (1950) was replaced by NITI Aayog on 1 January 2015. Below it are state planning boards and district planning committees (Art. 243ZD).
• Class 10's caution: having resources is not enough. Without matching technology and institutions, resource-rich regions stay backward. Colonisers used better technology to exploit the resources of colonies.

9. Land as a resource: relief, utilisation and degradation (overview)

Read the detailed note →

• Land is finite, so it needs careful planning. About 95% of our basic needs for food, shelter and clothing come from land (Class 10).
• Relief shares (Class 10, Fig. 1.3):
• 43% plains: farming and industry;
• 30% mountains: rivers that flow all year, tourism, ecology;

• 27% plateaus: minerals, fossil fuels, forests.

• Land use depends on physical factors (topography, climate, soil) and human factors (population density, technology, culture).

• India's area is 3.28 million sq km, but land-use data cover only about 93% of it. Most north-eastern states except Assam do not fully report, and areas held by Pakistan and China are not surveyed. The land-use categories and figures are covered in land-use-farming-systems.
• Human causes of land degradation, by region:
• mining and deforestation: Jharkhand, Chhattisgarh, Madhya Pradesh, Odisha;
• overgrazing: Gujarat, Rajasthan, Madhya Pradesh, Maharashtra;
• over-irrigation causing waterlogging, salinity and alkalinity: Punjab, Haryana, western Uttar Pradesh;

• dust from grinding limestone, calcite and soapstone, and industrial effluents.

• Remedies: afforestation, grazing control, shelter belts, thorny bushes to hold sand dunes, controlled mining, and treating effluents before disposal.

• ISRO-SAC Atlas (2021): about 97.85 million ha (29.7% of India) was degraded in 2018-19. India aims to restore 26 million ha by 2030 (announced at UNCCD COP14, New Delhi, 2019).

10. Stewardship today: regeneration, circular economy and Mission LiFE

Read the detailed note →

• Stewardship (Class 8) means caring for resources:
• use renewables so that nature can restore and regenerate them;

• use non-renewables carefully until substitutes are found.

• Punjab caselet:

• Cause: high-yielding varieties of wheat and paddy (1960s) need a lot of water, and free farm power encouraged over-pumping.

• Effect: almost 80% of Punjab's area is classed as "overexploited" for groundwater. In large parts the water table is below about 30 m (June 2022), and farm chemicals have polluted the groundwater.

• Sikkim became a 100% organic state in 2016. Biodiversity and tourism grew, and farm incomes rose about 20% (Class 8).

• Cement is one of the most polluting industries, and the Central Pollution Control Board has set guidelines for it. Alternatives include mud buildings (Auroville Earth Institute).
• International Solar Alliance: launched by India and France in 2015, with headquarters in Gurugram. Bhadla Solar Park is in Rajasthan.
• Circular economy: keep materials in use by designing out waste and by reusing, repairing, remanufacturing and recycling, instead of "take-make-dispose". India's tools include extended producer responsibility (EPR) rules of 2022 for plastic, e-waste and battery waste, and NITI Aayog-led action plans (verify current).
• Mission LiFE (Lifestyle for Environment): launched on 20 October 2022 at Ekta Nagar (Kevadia), Gujarat, with the UN Secretary-General. It asks people to save energy and water and avoid single-use plastic.

• The main cause of land degradation in Punjab is over-irrigation, not intensive cultivation.

Mains — GS-I and GS-III themes

1. "Resources are not, they become." Explain with Indian examples how technology and institutions turn natural materials into resources.
2. Why are India's mineral-rich states among its poorest? Discuss the resource curse and the responses (DMF, PESA, benefit-sharing).
3. Uneven resource endowment calls for balanced regional planning. Discuss India's three-step resource planning and its gaps.
4. From Stockholm to the SDGs: trace how sustainable development evolved and India's stand (poverty as polluter, CBDR).
5. Are commons in India a tragedy or a success of collective management? Use groundwater, village pastures and community forests.
6. Circular economy and lifestyle change (LiFE) as a complement to supply-side sustainability.
