Sustainable development

Also called: Sustainable economic development · Topic: Natural Resources: Classification, Planning and Sustainable Use · NCERT: Class 7, Ch 3 "Climates of India"; Class 7, Ch 1 "The Story of Indian Farming"; Class 8, Ch 1 "Natural Resources and Their Use"; Class 10, Ch 1 "Resources and Development"; Class 12, Ch 5 "Mineral and Energy Resources"; Class 12, Ch 6 "Planning and Sustainable Development in Indian Context"

Meaning

Sustainable development is development that meets the needs of the present without harming the ability of future generations to meet their own needs [5][6]. It means growing the economy while keeping nature healthy and sharing benefits fairly, so that resources last for humankind's common future.

It matters because a few people and countries have used resources without limit. This led to resource depletion (resources getting used up), pollution and a wide gap between rich and poor. Sustainable development is the world's main answer to this problem. It guides India's laws, its planning and its work on the SDGs.

Explanation

How the idea grew: from "sustainable yield" to one framework

• The older, narrow idea was sustainable yield [6]
• It meant taking only as many fish or trees as can grow back.

• It looked at one resource at a time.

• The Brundtland Report widened it [6]

• The UN set up the World Commission on Environment and Development (WCED) in 1983 [6].
• Its chair was Gro Harlem Brundtland, Prime Minister of Norway [5][6].
• Its report, Our Common Future (1987), is known as the Brundtland Report [5][6].

• It joined economic policy and ecological policy into one framework [6].

• Class 10 NCERT's simpler version: development that does not damage the environment, where development today does not cut into what future generations need.

Two key concepts in the report: needs and limits

• Needs: the basic needs of the world's poor come first [6].
• Limits: the state of technology and social organisation limits how far the environment can meet present and future needs [6].
• What this means: sustainable development is first about fair shares and only then about technology.

Three pillars to balance

Pillar	Simple meaning	Later "5 P" label
Ecological (environmental)	Keep air, water, soil and wildlife healthy	Planet
Social	Fair shares, equity (fairness), health, education	People
Economic	Growth, jobs, income	Prosperity

• A project is sustainable only when all three stay in balance.
• If one pillar grows at the cost of another, for example income at the cost of soil, the project is not sustainable.

Roots and debates

• Indian and Gandhian roots
• Gandhi: "There is enough for everybody's need and not for anybody's greed." He wanted "production by the masses" (many people making goods in their own villages with simple tools), not "mass production" (big factories with heavy machines).
• Lokasangraha (from the Bhagavad Gita) means doing one's duty for the good of all. Applied to resources, it means taking only what keeps society and nature healthy.
• Stewardship means humans are caretakers of nature, not its owners. We must pass nature on unharmed to the next generation.

• E.F. Schumacher, Small is Beautiful (first published 1973 [10]; NCERT: 1974). He argued that "bigness" (large industries and large cities) uses up natural resources [10]. He proposed intermediate technology: cheap, small tools that local people can run and that create jobs.

• Weak vs strong sustainability

• Weak: natural capital (forests, minerals) can be swapped for human-made capital (roads, factories), as long as total wealth does not fall.

• Strong: some natural capital, such as the ozone layer, biodiversity and groundwater, cannot be replaced. It must be kept whole.

• Green growth vs degrowth

• Green growth: keep growing, but use cleaner technology.
• Degrowth: rich countries must cut their total production and consumption, because the Earth's limits are real.

Where it occurs

• Stockholm, Sweden (5-16 June 1972): the UN Conference on the Human Environment, the first UN conference on international environment issues [2]. Delegations from 114 governments attended [2].
• It led to UNEP, set up in December 1972, with its headquarters in Nairobi, Kenya [2].
• 5 June became World Environment Day, which UNEP has led every year since 1973 [3][4].

• Indira Gandhi said that poverty and need are the greatest polluters, so development and the environment cannot be separated.

• Rio de Janeiro, Brazil (June 1992): the Rio Earth Summit, the first International Earth Summit.

• More than 178 countries adopted Agenda 21, a plan of action for the 21st century [7].
• Each local government is asked to make a Local Agenda 21 (its own local plan).

• Rio also produced the Global Forest Principles and a declaration on global climatic change and biological diversity.

• The world (2015 to 2030): the 2030 Agenda, adopted at the UN Sustainable Development Summit in September 2015 [8]. It set 17 SDGs and 169 targets for all countries [8][9].

• India's laws:
• Wildlife (Protection) Act (1972)
• Water (Prevention and Control of Pollution) Act (1974)
• 42nd Amendment (1976), which added Art. 48A and Art. 51A(g)

• Air (Prevention and Control of Pollution) Act (1981)

• Indira Gandhi Canal, Rajasthan: the canal brings water to the dry Thar Desert. It also caused waterlogging (soil that stays soaked with water) and soil salinity (salt building up in the soil).

• Sustainable measures:
  • strict water-use rules
  • citrus and other crops that need less water, instead of rice and sugarcane
  • afforestation (planting new forests)
  • shelterbelts (rows of trees that stop wind and sand)
  • reclaiming waterlogged and salty land

Don't confuse with

• Sustainable yield: this means harvesting only what grows back, for one resource such as fish or trees. Sustainable development is wider. It links economy, society and ecology [6].
• Resource conservation: this means using resources carefully and cutting waste. It is one tool within sustainable development, which also gives priority to the needs of the poor.
• Green growth: this is one view inside the sustainability debate (grow, but with clean technology). It is not the same as sustainable development, and degrowth is the opposing view.
• MDGs vs SDGs: the MDGs ended in 2015 and mainly targeted developing countries. The SDGs apply to all countries [8].

Prelims Hooks

• Gro Harlem Brundtland was Prime Minister of Norway, not Sweden [5][6]. Stockholm (1972) is in Sweden. This is a common trap.
• The WCED was set up in 1983, and its report came in 1987 (Our Common Future) [6]. Do not mix up the two years.
• The Brundtland Report's two key concepts are "needs" and "limits" [6]. "Needs" gives priority to the world's poor.
• Agenda 21 comes from Rio (1992), not Stockholm (1972). More than 178 countries adopted it [7].
• Correct order: Club of Rome (1968) → Stockholm (1972) → Small is Beautiful (1973) → WCED (1983) → Brundtland Report (1987) → Rio (1992) → SDGs (2015).
• SDGs: 17 goals, 169 targets, deadline 2030 [8][9]. UNEP's headquarters are in Nairobi, Kenya [2].

Mains Points

• One idea runs from Gandhi to Brundtland: fair shares come first
• Gandhi said "need, not greed". Schumacher argued for small-scale technology. Brundtland put the needs of the poor first [6].

• So resource depletion is mainly a problem of fair distribution, not only of technology. This point is useful for GS-I and GS-III answers on resources.

• "Poverty is the greatest polluter" shaped India's approach

• India argued at Stockholm that environment and development must go together.
• This led to the Wildlife Act 1972, the Water Act 1974, the Air Act 1981 and Arts. 48A and 51A(g).

• The same idea later became the climate principle of common but differentiated responsibilities: all countries must act, but rich countries carry a bigger share.

• The three pillars are hard to balance in practice. The Indira Gandhi Canal shows this:

• Economic gain: irrigation in the Thar.
• Ecological cost: waterlogging and salinity.
• Fix: changing the crop pattern, planting shelterbelts and following strict water-use rules.
• For a critical answer, add the open debates: weak vs strong sustainability, green growth vs degrowth, and the gap between global targets (Agenda 21, SDGs) and local action (Local Agenda 21, panchayat-level planning).
