Study Notes
- Numerous items make life comfortable in villages and towns
Resource Definition
- Resources can be used to satisfy needs if technologically accessible, economically feasible, and culturally acceptable
Transformation Process
- Transformation of available things involves an interactive relationship between nature, technology, and institutions
Human Role
- Humans interact with nature through technology, creating institutions to accelerate economic development; they transform available material into resources
Resource Classification
- Classified on origin (biotic/abiotic), exhaustibility (renewable/non-renewable), ownership (individual/community/national/international), and development status (potential/developed/stock/reserves)
Resources Importance
- Vital for human survival and maintaining life quality
- Indiscriminate usage has led to depletion, accumulation in few hands, and global ecological crises
Major Problems due to Indiscriminate Exploitation
- Depletion of resources for satisfying the greed
- Accumulation of resources in few hands, dividing society into haves/have-nots (rich/poor)
- Global warming, ozone layer depletion, environmental pollution, and land degradation
Equitable Resource Distribution
- Essential for sustained life quality and global peace
- Unsustainable resource depletion endangers the planet
Resource Planning Requirement

Resource Planning Strategy
- Widely accepted strategy for the judicious use of resources
- Important in countries like India, which has enormous divesity in the availability of resources
Regional Resource Diversity
- Some regions are self-sufficient; others have acute shortages of vital resources
Regional Examples
- 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
- Ladakh is isolated and lacks water, infrastructure, and some minerals but has a rich cultural heritage
Resource Planning Complexity
- Involves identification and inventory of resources across regions, using surveying, mapping, and qualitative/quantitative estimation
- Requires a planning structure with appropriate technology, skill, and institutions
India's Efforts
- India has make concerted efforts for achieving resource planning goals by, using Five-Year Plans after Independence
Development Conditions
- Availability of resources is necessary, corresponding changes in technology and institutions
- The rich resource of colonies attracted foreign invaders aiming to exploit resources and establish supremacy
- Resources contribute to development when accompanied by technological development and institutional changes
India's Experience
- India's development involves resource availability, technology, human resources, and historical experiences
Resource Conservation
- Vital for any developmental activity, irrational consumption, and over-utilisation of resources. This can lead to socio-economic and environmental problems
Conservation Importance
- Resource over-consumption leads to socio-economic and environmental issues
- Resource conservation at various levels is important, requiring various methods to solve this
Land Resources
- Supports natural vegetation, wildlife, human life, economic activities, transport, and communication systems
Land Usage
- It is important to use carefully planned
Land Distribution
- Plains: 43% (agriculture and industry)
- Mountains: 30% (rivers, tourism, and ecological aspects)
- Plateaus: 27% (minerals, fossil fuels, and forests)
Land Utilisation
Land Resources are used for:
- Forests
- Land not available for cultivation:
- Barren and wasteland
- Land for non-agricultural uses (buildings, roads, factories)
- Other uncultivated land (excluding fallow land):
- Permanent pastures and grazing land
- Land under miscellaneous tree crops/groves
- Culturable wasteland (uncultivated for over 5 years)
- Fallow lands:
- Current fallow (1 year or less)
- Other than current fallow (1-5 years)
- Net sown area:
- Physical extent of land where crops are sown and harvested
- Gross cropped area:
- Area sown more than once + net sown area
Land Use Patterns
- Determined by physical factors like topography, climate, and soil types, and human factors like population density, technology, culture, and traditions
Soil Composition
- Soil consists of organic (humus) and inorganic materials
Factors for Soil Formation
- Soil formation includes color, thickness, texture, age chemical, and physical properties
- The soils of India are then classified into different types
Soil Classification Factors
- India features variations in relief, vegetation, climate, and landforms. These variations have contributed to developing various soil types
Alluvial Soils
- Most widely spread and important soil type.
- Made by Himalayan river systems (Indus, Ganga, Brahmaputra).
Soil Extension
- This soil type extends to Rajasthan and Gujarat which is through a narrow corridor. Found in eastern coastal plains (deltas of Mahanadi, Godavari, Krishna, Kaveri rivers)
Soil Properties
- Consists of sand, silt, and clay which is inland towards river valleys, where the overall soil particles appearing a bit on the larger size. Also has a great amount of potash, phosphoric acid and lime making it idea for growing sugarcane, paddy, wheat, cereal and pulse crops
Older vs Newer Alluvial
- Soil categorized by older alluvial (Bangar) and new alluvial (Khadar)
- bangar concentration of kanker nodules, fine particles, and increased fertility over bangar
Black Soils
- Black in color and also known as regur soils These soils
- These soils are well suited for cotton
Soil Formation
- Climate and parent rock material are important for formation
Soil coverage
- Deccan plateau (Basalt) and made up of lava flows
- Covers plateaus in Maharashtra, Saurashtra, Malwa, Madhya Pradesh, Chhattisgarh
- Extends southeast along Godavari and Krishna valleys
Black Soil Makeup
- Made up of clayey material and has the Known for capacity to hold moisture
- Are rich in soil nutrients like calcium carbonate, magnesium, potash, and lime and poor in phosphoric contents
Red and Yellow Soils
- Red soil develops on crystalline igneous rocks with low rainfall (eastern and southern Deccan plateau) where Yellow and red soils occur in parts of Odisha, Chhattisgarh, middle Ganga plain, Western Ghats
- Reddish color due to iron diffusion in crystalline and metamorphic rocks, yellow in hydrated form
Laterite Decomposition
- Under tropical and subtropical climate with wet/dry seasons
- From intense leaching due to heavy rain, leading to acidity (pH<6.0) and plant nutrient deficiency
- Mostly in southern states, Western Ghats region of Maharashtra, Odisha, West Bengal, and Northeast regions
Soil Characteristics
- Deciduous and evergreen forests support humus-rich soils, whilst lacking vegetation and semi-arid conditions results in poor humus
Soil Erosion and Conservation
- Soil covering removal and the subsequent washing down described as soil erosion
Soil Balance
- Process of soil formation and erosion, which occurs simultaneously, which in turn creates balance between them Two
- It is sometimes disturbed by deforestation, over-grazing, construction, mining etc.
Soil Damage
- Running water cuts through clayey soils, forming gullies which also make it unfit for cultivation and labelled as bad land in the Chambal basin or ravines
- Water flowing as a sheet over large areas down a slope, which then forms a sheet of erosion
- Wind blows loose soil off flat or sloping which translates to wind erosion, resulting from defective farming methods
- Ploughing along contour lines decelerates water flow
- Contour ploughing involves cutting steps to create terraces to restrict erosion
- Western and central Himalayas have well developed terrace farming
- Strip cropping involves grass strips between crops
- Planting lines of trees to act as shelter belts help stabilise sand dunes and stabilise the desert to prevent erosion in western India
