Resources and Development – Comprehensive Notes (India)

RESOURCE: CONCEPT AND INTERACTION

  • Definition: 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 as a ‘Resource’.
  • Interaction model: Transformation of environmental things involves an interactive relationship between nature, technology and institutions.
  • Human–nature relationship:
    • Humans interact with nature through technology.
    • Institutions are created to accelerate economic development.
  • Resources are not free gifts of nature; they are a function of human activities.
  • Humans themselves are essential components of resources; they transform material available in our environment into resources and use them.
  • Classification of resources (as discussed in the text):
    • 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.
  • Life-context examples:
    • Identify and name items used to make life comfortable in villages and towns; list items and material used in their making.
  • Visual aids mentioned:
    • Fig. 1.1: Interdependent relationship between nature, technology and institutions.
    • Fig. 1.2: Classification of resources.

RESOURCE CLASSIFICATION AND DEVELOPMENT CONTEXT

  • Resources are vital for human survival and maintaining quality of life.
  • Early belief: Resources are free gifts of nature, leading to indiscriminate use.
  • Resulting problems:
    • Depletion of resources due to greed.
    • Inequitable distribution; creates haves and have-nots.
    • Global ecological crises: global warming, ozone layer depletion, environmental pollution, land degradation.
  • Necessity: An equitable distribution of resources is essential for sustained quality of life and global peace.
  • If depletion continues, the future of the planet is at risk; resource planning is essential for sustainable existence.
  • Sustainable existence is a component of sustainable development.
  • Sustainable development (definition):
    • Development should take place without damaging the environment, and development in the present should not compromise the needs of future generations.
    • Source reference: Rio de Janeiro Earth Summit, 1992.
  • Rio Earth Summit (1992) highlights:
    • More than 100 heads of state gathered in Rio de Janeiro, Brazil.
    • Addressed urgent problems of environmental protection and socio-economic development at a global level.
    • Signed Declaration on Global Climate Change and Biological Diversity.
    • The Rio Convention endorsed global Forest Principles and adopted Agenda 21 for achieving Sustainable Development in the 21st century.
  • Agenda 21 (1982 UNCED, Rio):
    • A global plan to achieve sustainable development.
    • One major objective: every local government should draw its own local Agenda 21.
  • RESOURCE PLANNING (in general and in India):
    • Planning is the strategy for judicious use of resources, crucial for a country with diverse resource availability.
    • Regions can be resource-rich but economically backward, or resource-poor yet economically developed; planning must address regional imbalances.
  • Historical and global perspectives on conservation:
    • Colonial history shows rich resources in colonies attracted foreign invaders; development required technology and institutional changes.
    • Gandhi’s view on resource conservation: importance of conserving resources; quotes emphasize planning and responsible use (paraphrased here).
    • Club of Rome (1968) advocated resource conservation.
    • Schumacher (Small is Beautiful, 1974) contributed to Gandhian-style resource conservation.
    • Brundtland Commission Report (Our Common Future, 1987) introduced the concept of Sustainable Development.
    • Earth Summit (Rio, 1992) reinforced global sustainable development goals.
  • RESOURCE PLANNING: Indian context
    • Resource planning involves:
    • (i) Identification and inventory of resources across regions (surveys, mapping; qualitative and quantitative estimation and measurement).
    • (ii) Evolution of a planning structure with appropriate technology, skill and institutional setup for implementing resource development plans.
    • (iii) Matching resource development plans with overall national development plans.
    • India’s ongoing efforts for resource planning since the First Five Year Plan.
    • Availability of resources is necessary for development, but not sufficient without changes in land use, technology and institutions.
    • Gandhi’s emphasis on production by the masses rather than mass production.
    • Global references: Club of Rome (1968), Schumacher (1974), Brundtland Commission (1987).

CONSERVATION OF RESOURCES AND GANDHIAN PERSPECTIVE

  • Resource conservation is essential due to irrational consumption and over-utilisation causing socio-economic and environmental problems.
  • Gandhi’s stance on resource conservation emphasizes prudent use and non-wasteful practices.
  • The need for planning at multiple levels (local to national) to conserve and manage resources for future generations.

LAND RESOURCES: AN OVERVIEW

  • Land as a base for life and economic activity:
    • We live, work, and conduct economic activities on land; land supports natural vegetation, wildlife, human life, transport and communication.
    • Land is finite; therefore, careful use is essential.
  • India's land area and relief features:
    • Total geographical area: Aextgeo=3.28imes106extkm2A_{ ext{geo}} = 3.28 imes 10^{6} ext{ km}^2.
    • Land use data available for about 93% of the total area due to incomplete surveying in certain regions (notably north-eastern states and border areas).
  • Land use distribution (as described):
    • 43% plain land.
    • 30% mountainous terrain.
    • 27% plateau region.
  • Net sown area (NSA) and gross cropped area (GCA):
    • NSA: the physical extent of land on which crops are sown and harvested.
    • GCA: NSA plus land sown more than once in an agricultural year.
    • NSA data varies by state; for instance, NSA is over 80% in Punjab and Haryana, and less than 10% in Arunachal Pradesh, Mizoram, Manipur and Andaman & Nicobar Islands.
  • Forest policy reference: forest area in the country is far lower than the desired 33% of geographical area (National Forest Policy, 1952).
  • Land use data interpretation exercise:
    • Compare two pie charts (land use vs. forests) and analyze why NSA and forest shares changed marginally from 1960-61 to 2019-20.
    • Consider why permanent pasture area decreased and how India feeds its large cattle population on pasture land, along with the possible consequences.
  • Land use planning takeaway: land is to be used for multiple purposes (agriculture, forestry, settlements, industry, etc.) while conserving ecological balance.
  • Historical and international perspectives on land use and conservation:
    • Gandhi emphasized resource planning and sustainable practices.
    • Club of Rome (1968), Schumacher (1974) and Brundtland Commission (1987) contributed to resource conservation discourse.
    • Earth Summit (1992) reinforced sustainable development on a global scale.

LAND RESOURCES AND USE PATTERNS IN INDIA

  • Factors influencing land use:
    • Physical factors: topography, climate, soil types.
    • Human factors: population density, technological capability, culture and traditions.
  • National land-use policy frame:
    • The goal is to balance resource availability with land use needs, ensuring sustainable development and reducing regional disparities.

SOIL AS A RESOURCE

  • Soil importance:
    • The most important renewable natural resource; medium for plant growth; supports life, biodiversity and agriculture.
    • Soil is a living system; formation takes millions of years (only a few cm thick changes over long timescales).
  • Soil formation factors:
    • Relief (topography), parent rock, climate, vegetation, and time.
    • Processes: weathering, actions of running water, wind, glaciers; decomposers and organic changes in soil (humus) and inorganic materials.
  • Subsoil and topsoil components (soil profile concept):
    • Top soil (upper layer)
    • Subsoil (below topsoil)
    • Substratum (weathered parent rock material)
    • Unweathered parent bed rock
  • Soil classification and India’s soil types have been influenced by relief, climate and vegetation.

TYPES OF SOILS IN INDIA

  • Alluvial soil:
    • Most widely spread and important soil; covers northern plains, deltas of Indus, Ganga, Brahmaputra; also extends to parts of Rajasthan and Gujarat.
    • Highly fertile; contains adequate proportions of potassium (K), phosphoric acid (P2O5) and lime (CaCO3).
    • Suitable for crops like sugarcane, paddy, wheat and other cereals and pulses.
    • Alluvial soils can be old (Bangar) or new (Khadar); clay content and particle size vary with location (coarser near break of slope, finer in other areas).
  • Black soil (regur):
    • Typical of the Deccan trap region; spread across Maharashtra, Saurashtra, Malwa, MP and Chhattisgarh; extends along the Godavari and Krishna valleys.
    • Fine clay texture; high moisture retention; whole property supports cotton cultivation.
    • Soils are generally poor in phosphoric content; prone to deep cracking in hot weather which aids aeration when moist; difficult to work when wet.
  • Red and Yellow soils:
    • Develop on crystalline igneous rocks in areas with relatively low rainfall (eastern and southern Deccan plateau), Odisha, parts of Chhattisgarh, southern Ganga plain, and Western Ghats piedmont.
    • Red color due to diffusion of iron in rocks; yellow when in hydrated form.
  • Laterite soil:
    • Derived from Latin later, meaning brick.
    • Develops under tropical/subtropical climate with alternating wet and dry seasons; intense leaching due to heavy rainfall.
    • Deep to very deep, acidic (pH < 6), generally deficient in plant nutrients; supports forests but is humus-poor under sparse vegetation.
    • Once managed with proper soil conservation techniques in hilly areas (Karnataka, Kerala, Tamil Nadu), laterite soil can be useful for tea, coffee; cashew in Tamil Nadu, Andhra Pradesh, Kerala.
  • Arid soils:
    • Range from red to brown; sandy texture; saline in nature; high salt content in some areas.
    • High temperature, rapid evaporation, low humus and moisture; deeper horizons often contain Kankar (calcium carbonate-rich layer) which can restrict water infiltration.
    • Can become cultivable with proper irrigation (example: western Rajasthan).
  • Forest soils:
    • Found in hilly and mountainous areas; texture varies with environment; loamy and silty in valleys, coarser on upper slopes.
    • In Himalayan valleys and lower altitudes, these soils can be fertile, especially where adequate rainfall supports forest cover.

SOIL EROSION AND CONSERVATION

  • Soil erosion concept:
    • Erosion is the denudation and washing away of the soil cover; ongoing soil formation and erosion occur simultaneously; balance is key.
    • Human activities (deforestation, overgrazing, mining, construction) and natural forces (wind, water, glaciers) can disturb the balance.
  • Types and consequences:
    • Gullies: deep channels formed by running water in clayey soils.
    • Ravines in certain basins (e.g., Chambal).
    • Sheet erosion: soil washed away as a sheet over a slope.
    • Wind erosion: loose soil blown away from flat or sloping land.
  • Conservation measures:
    • Contour ploughing to slow runoff and reduce erosion.
    • Terrace cultivation to cut the slope and reduce erosion; large-scale terrace farming in Western and Central Himalayas.
    • Strip cropping and shelter belts (rows of trees) to break wind and stabilize soils; shelter belts help stabilize sand dunes and deserts in western India.
    • Proper land/waste land management, controlled mining, and treatment of industrial effluents to reduce degradation.
