Chapter 1: Resources and Development (Geography)

Introduction

This chapter opens with a simple question: can you name the things that make life comfortable in our villages and towns, and the materials they are made of? Everything we use comes from our environment — but not everything in the environment is automatically a resource. The chapter defines a resource, classifies resources, explains why careless use has created problems, and then studies two of India's most important resources in detail: land and soil.

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

Key Concepts

Resources are not free gifts of nature

The book argues that resources are a function of human activities. Humans transform material in the environment into resources through an interactive relationship between nature, technology and institutions (Fig. 1.1). Human beings themselves are essential components of resources.

Classification of resources

On the basis of origin — biotic and abiotic

On the basis of exhaustibility — renewable and non-renewable

On the basis of ownership — individual, community, national and international

On the basis of status of development — potential, developed stock and reserves

Development of resources and sustainable development

Sustainable economic development means "development should take place without damaging the environment, and development in the present should not compromise with the needs of the future generations."

Believing resources to be free gifts of nature, humans used them indiscriminately. This led to:

depletion of resources to satisfy the greed of a few individuals;

accumulation of resources in few hands, dividing society into haves and have-nots;

global ecological crises — global warming, ozone layer depletion, environmental pollution and land degradation.

Rio de Janeiro Earth Summit, 1992: in June 1992, more than 100 heads of states met in Rio de Janeiro, Brazil, for the first International Earth Summit. They signed the Declaration on Global Climatic Change and Biological Diversity; the Rio Convention endorsed the global Forest Principles and adopted Agenda 21 for sustainable development in the 21st century.

Agenda 21 was signed at the UN Conference on Environment and Development (UNCED). It aims to combat environmental damage, poverty and disease through global cooperation. One major objective: every local government should draw its own local Agenda 21.

Resource planning

India has enormous diversity in resource availability:

Jharkhand, Chhattisgarh and Madhya Pradesh — rich in minerals and coal deposits

Arunachal Pradesh — abundant water resources but lacks infrastructural development

Rajasthan — well endowed with solar and wind energy but lacks water

Ladakh (cold desert) — rich cultural heritage but deficient in water, infrastructure and some vital minerals

Resource planning in India involves three steps:

Identification and inventory of resources — surveying, mapping, qualitative and quantitative estimation.

Evolving a planning structure with appropriate technology, skill and institutional set-up.

Matching resource development plans with overall national development plans.

India has made efforts towards resource planning since the First Five Year Plan. Availability of resources alone is not enough — regions rich in resources can still be economically backward. Colonisers exploited colonies' resources because of their higher technological development. So resources contribute to development only with appropriate technology and institutional changes.

Conservation of resources

Gandhiji: "There is enough for everybody's need and not for anybody's greed." He opposed mass production and wanted production by the masses.

Club of Rome (1968) — first advocated resource conservation systematically at the international level.

*Schumacher, Small is Beautiful* (1974)** — presented Gandhian philosophy again.

Brundtland Commission Report (1987) — introduced the concept of Sustainable Development; published as Our Common Future.

Earth Summit, Rio de Janeiro (1992).

Land resources and land use

India's relief: about 43 per cent plains (agriculture and industry), 30 per cent mountains (perennial rivers, tourism, ecology), 27 per cent plateaus (minerals, fossil fuels, forests).

Land use categories:

Forests

Land not available for cultivation — barren and waste land; land put to non-agricultural uses

Other uncultivated land (excluding fallow) — permanent pastures; land under miscellaneous tree crops; culturable waste land (left uncultivated for more than 5 agricultural years)

Fallow lands — current fallow (one or less than one agricultural year); other than current fallow (past 1 to 5 agricultural years)

Net sown area — the physical extent of land on which crops are sown and harvested

Gross cropped area = area sown more than once in an agricultural year + net sown area

Key facts: total geographical area 3.28 million sq km; land use data available for only 93 per cent. Including fallow lands, net sown area comes to about 54 per cent of the reporting area. Net sown area is over 80 per cent in Punjab and Haryana and less than 10 per cent in Arunachal Pradesh, Mizoram, Manipur and Andaman & Nicobar Islands. The National Forest Policy (1952) outlined a desired 33 per cent forest cover.

Land degradation and conservation

Deforestation due to mining — Jharkhand, Chhattisgarh, Madhya Pradesh, Odisha

Overgrazing — Gujarat, Rajasthan, Madhya Pradesh, Maharashtra

Over-irrigation (waterlogging → salinity and alkalinity) — Punjab, Haryana, western Uttar Pradesh

Mineral processing (grinding limestone, calcite, soapstone) produces dust that retards water infiltration

Industrial effluents pollute land and water

Solutions: afforestation, proper grazing management, shelter belts, control on overgrazing, stabilising sand dunes with thorny bushes, managing waste lands, controlling mining, treating industrial effluents.

Soil as a resource

Soil is the most important natural resource; it takes millions of years to form soil up to a few cm in depth. Factors of formation: relief, parent rock, climate, vegetation, other life forms and time. Soil profile: top soil → subsoil → substratum → unweathered parent bed rock.

Soil types of India:

Alluvial — most widespread; entire northern plains; deposited by the Indus, Ganga and Brahmaputra; also in Rajasthan and Gujarat and in deltas of the Mahanadi, Godavari, Krishna and Kaveri. Coarse near the break of slope (Duars, Chos, Terai). Bangar (old, more kankar) and Khadar (new, more fertile). Rich in potash, phosphoric acid and lime — good for sugarcane, paddy, wheat, cereals and pulses.

Black (regur) — ideal for cotton ("black cotton soil"); Deccan trap (basalt); Maharashtra, Saurashtra, Malwa, Madhya Pradesh, Chhattisgarh, Godavari and Krishna valleys. Clayey, holds moisture, rich in calcium carbonate, magnesium, potash and lime; poor in phosphoric content; deep cracks in hot weather.

Red and yellow — on crystalline igneous rocks in low-rainfall eastern and southern Deccan; red from diffusion of iron, yellow when hydrated.

Laterite — from Latin later (brick); intense leaching under heavy rain; acidic (pH < 6.0); after conservation useful for tea and coffee (Karnataka, Kerala, Tamil Nadu); red laterite suits cashew nut.

Arid — red to brown, sandy, saline; lower horizons have kankar; cultivable after irrigation (western Rajasthan).

Forest — hilly/mountainous areas; loamy/silty in valleys, coarse on upper slopes; acidic with low humus in snow-covered Himalayas.

Soil erosion and conservation

Gullies make land unfit — bad land; in the Chambal basin, ravines. Types: gully erosion, sheet erosion, wind erosion; also defective ploughing up and down the slope.

Conservation methods: contour ploughing, terrace cultivation (western and central Himalayas), strip cropping, shelter belts (stabilising sand dunes in western India).

Map Work

Major soil types on the map of India (alluvial, black, red and yellow, laterite, arid, forest).

States named for mining, overgrazing and over-irrigation degradation.

Board Exam Focus

1-mark MCQs: main cause of degradation in Punjab (over-irrigation); terrace cultivation state (Uttarakhand); black soil state (Maharashtra).

3-mark (30 words): three black-soil states and crop; soil of eastern river deltas with three features; steps to control soil erosion in hills.

5-mark (120 words): land use pattern and why forest land has barely increased since 1960-61; how technical and economic development increased resource consumption.

Model outline for soil erosion in hills: contour ploughing → terrace farming → strip cropping → afforestation/shelter belts, each with one line of explanation.

Local governments drawing their own "local Agenda 21", rooftop solar in water-scarce Rajasthan, and shelter belts in the Thar all show resource planning in action.

Common Mistakes

Saying resources are "free gifts of nature" — the book says they are a function of human activities.

Mixing up stock (technology not yet available) with reserves (can be used with existing technology).

Confusing Bangar (old, kankar) with Khadar (new, more fertile).

Writing that black soil is rich in phosphorus — it is poor in phosphoric content.

Mixing up the cause of degradation by state: over-irrigation is Punjab/Haryana/western UP; mining is Jharkhand/Chhattisgarh/MP/Odisha.

💡 Key Learning Points

✓Define a resource using the three conditions: technologically accessible, economically feasible and culturally acceptable.
✓Classify resources by origin, exhaustibility, ownership and status of development.
✓Explain sustainable development, the Rio Earth Summit (1992) and Agenda 21, and the three steps of resource planning in India.
✓Describe India's land use categories and the state-wise causes and remedies of land degradation.
✓Identify India's six major soil types with their regions and features, and methods of soil conservation.

👨‍🏫 Teaching Tips

→Start with the opening activity: students list household items and the materials they are made of, then test each against the three conditions of a resource.
→Draw the resource classification as a four-branch mind map on the board and have students add local examples to each branch.
→Make a 'state–cause–remedy' chart for land degradation (mining, overgrazing, over-irrigation) and link each to the map of India.
→Bring small soil samples (or photos) and let students sort them by colour and texture before introducing the six soil types.
→Demonstrate soil erosion with a tray of soil on a slope: pour water with and without 'contour ridges' to show why contour ploughing works.
→Use the Gandhi quote, Club of Rome, Schumacher and Brundtland as a timeline activity from 1968 to 1992.
→Assign the resource survey from the chapter: students interview neighbours on recycling of domestic/agricultural waste.
