Resources and Development - Class 10 Geography

Comprehensive vocabulary flashcards covering the concepts, definitions, classifications, land use patterns, degradation factors, soil profiles, and soil conservation techniques from Chapter 1: Resources and Development.

Resource

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

Biotic and Abiotic Resources

Classification of resources based on origin: Biotic resources are obtained from the biosphere and have life (e.g., human beings, flora, fauna, fisheries, livestock), whereas abiotic resources are composed of non-living things (e.g., rocks and metals).

Renewable and Non-Renewable Resources

Classification based on exhaustibility: Renewable resources can be renewed or reproduced by physical, chemical, or mechanical processes (e.g., solar, wind energy, water, forests), while non-renewable resources take millions of years in their formation and cannot be replenished once exhausted (e.g., minerals, fossil fuels such as coal).

Individual and Community-Owned Resources

Classification based on ownership: Individual resources are privately owned by individuals (e.g., farmers' plots, houses, pasture lands, ponds), whereas community-owned resources are accessible to all members of a community (e.g., grazing grounds, burial grounds, village ponds, public parks).

National and International Resources

National resources are all resources within the political boundaries and oceanic areas up to $12\text{ nautical miles}$ ($22.2\,km$) from the coast (territorial water); international resources are oceanic resources beyond $200\text{ nautical miles}$ of the Exclusive Economic Zone, regulated by international institutions.

Potential Resources

Resources found in a region that have not been utilized yet (e.g., solar and wind energy potential in Rajasthan and Gujarat).

Stock and Reserves

Stock refers to materials in the environment that have the potential to satisfy human needs but humans lack the appropriate technology to access them (e.g., hydrogen from water); reserves are the subset of stock that can be put into use with existing technical know-how but are conserved for future requirements.

Sustainable Economic Development

Development that takes place without damaging the environment, ensuring that development in the present does not compromise the needs of future generations.

Rio de Janeiro Earth Summit, 1992

The first International Earth Summit held in June $1992$ in Brazil,

It aimed to address environmental issues and promote sustainable development through international cooperation and policy implementation.

where over $100$ heads of state signed the Declaration on Global Climatic Change & Biological Diversity, endorsed the global Forest Principles

adopted Agenda 21.

Agenda 21

A global declaration adopted at the $1992$ UNCED in Rio de Janeiro to combat environmental damage, poverty, and disease through global cooperation on common interests, mutual needs, and shared responsibilities, with each local government drafting its own local Agenda 21.

Three Stages of Resource Planning in India

A complex process involving: (1) Identification and inventory of resources through surveying, mapping, and qualitative/quantitative estimation;

(2) Evolving a planning structure equipped with appropriate technology, skill, and institutional setup; and

(3) Matching resource development plans with overall national development plans.

Regional Resource Disparity in India

The uneven distribution of resources across Indian regions: Jharkhand, Chhattisgarh, and Madhya Pradesh are rich in minerals and coal; Arunachal Pradesh has abundant water but lacks infrastructure; Rajasthan has solar and wind energy but lacks water; and Ladakh has rich cultural heritage but is deficient in water, infrastructure, and vital minerals.

Gandhian Philosophy on Resource Conservation

The principle voiced by Mahatma Gandhi stating, 'There is enough for everybody’s need and not for any body’s greed,' attributing resource depletion to modern exploitative technology and advocating for production by the masses rather than mass production.

Historical Milestones in Resource Conservation

Key international contributions including the Club of Rome advocating resource conservation in $1968$, Schumacher presenting Gandhian philosophy in his book 'Small is Beautiful' in $1974$, and the Brundtland Commission Report introducing 'Sustainable Development' in $1987$ (published in 'Our Common Future').

India's Relief Features (Land Distribution)

The division of India's total land area into distinct relief types: $43\%$ plains (providing agricultural and industrial facilities), $30\%$ mountains (ensuring perennial river flow, tourism, and ecological balance), and $27\%$ plateaus (possessing reserves of minerals, fossil fuels, and forests).

Culturable Waste Land

Agricultural land left uncultivated for more than $5$ agricultural years.

Current Fallow Land

Agricultural land left without cultivation for one or less than one agricultural year to regain its fertility naturally.

Fallow Other Than Current Fallow

Agricultural land left uncultivated for the past $1$ to $5$ agricultural years.

Net Sown Area (NSA)

The total physical extent of land on which crops are sown and harvested at least once in an agricultural year.

Gross Cropped Area

The total area sown more than once in an agricultural year plus the Net Sown Area.

Factors Determining Land Use Pattern

Land utilization is determined by physical factors (topography, climate, soil types) and human factors (population density, technological capability, culture, and traditions).

National Forest Policy (1952)

An Indian policy outline establishing that an ideal minimum of $33\%$ of the geographical area should be under forest cover to maintain ecological balance and support forest-dwelling livelihoods.

Causes of Land Degradation by State

Regional human causes of degradation: Deforestation due to mining in Jharkhand, Chhattisgarh, Madhya Pradesh, and Odisha; Overgrazing in Gujarat, Rajasthan, Madhya Pradesh, and Maharashtra; Over-irrigation leading to waterlogging, salinity, and alkalinity in Punjab, Haryana, and Western Uttar Pradesh.

Mineral Processing Dust (Land Degradation)

The generation of massive atmospheric dust from the grinding of limestone for the cement industry and calcite and soapstone for the ceramic industry, which settles on land and retards the infiltration of water into the soil.

Soil Profile

The vertical section of soil showing four distinct horizons: Topsoil (the upper soil layer rich in humus), Subsoil (weathered rocks, sand, silt, and clay), Substratum (weathered parent rock material), and Unweathered parent bed rock.

Alluvial Soil

The most widely spread, fertile soil deposited by the Indus, Ganga, and Brahmaputra rivers in northern plains, coastal deltas, and parts of Rajasthan and Gujarat; contains sand, silt, clay, potash, phosphoric acid, and lime.

Bangar and Khadar

The two age-based classifications of alluvial soil: Bangar is old alluvium with a higher concentration of calcareous kankar nodules and lower fertility; Khadar is new alluvium composed of finer particles and higher fertility.

Black Soil (Regur Soil)

A clayey, moisture-retentive soil formed from volcanic basalt lava flows across the Deccan trap (Maharashtra, Saurashtra, Malwa, MP); rich in calcium carbonate, magnesium, potash, and lime, poor in phosphoric content, and ideal for cotton cultivation.

Red and Yellow Soils

Soils developed on crystalline igneous rocks in low-rainfall areas of the eastern and southern Deccan plateau, Odisha, and Chhattisgarh; reddish in color due to iron diffusion in crystalline/metamorphic rocks and yellow when hydrated.

Laterite Soil

A soil derived from the Latin word 'later' (meaning brick), formed in tropical and subtropical climates under alternate wet and dry seasons with intense leaching; typically deep, acidic ($pH < 6.0$), humus-poor under sparse vegetation, and suitable for tea, coffee, and cashew nuts.

Arid Soil

A soil ranging from red to brown in color, sandy in texture, and saline in nature; lacks humus and moisture due to dry climate and fast evaporation, with lower horizons occupied by kankar nodules that restrict water infiltration.

Forest Soil

Soils found in hilly and mountainous rainforest regions; loamy and silty on valley floors, coarse-grained on upper slopes, acidic with low humus in Himalayan snow-covered zones, and fertile on river terraces and alluvial fans.

Soil Erosion

The denudation of the soil cover and subsequent washing down caused by natural forces (running water, wind, glaciers) and accelerated by human activities (deforestation, overgrazing, mining, defective farming).

Gully Erosion and Ravines

A form of erosion where running water carves deep channels into clayey soils, turning the land into uncultivable 'bad land,' which is specifically referred to as 'ravines' in the Chambal basin.

Sheet Erosion and Wind Erosion

Sheet erosion occurs when water flows as a broad sheet down a slope washing away the topsoil layer; wind erosion occurs when loose, dry soil is blown off flat or sloping ground by the wind.

Contour Ploughing

The soil conservation technique of ploughing across slope contour lines at right angles to decelerate the flow of water down hillside slopes.

Strip Cropping

The agricultural conservation method of dividing large fields into strips and leaving strips of grass to grow between crops to break the force of the wind.

Shelter Belts

The practice of planting rows and lines of trees along field boundaries to break wind speed, highly effective in stabilizing sand dunes and arid deserts in western India.
