MP Board Class 10 SST Geography Ch 1: Resources Dev Notes
Class 10 Social Science (सामाजिक विज्ञान) — Geography Chapter 1: संसाधन एवं विकास (Resources and Development) — This chapter introduces the concept of resources — everything available in our environment that can be used to satisfy our needs, provided it is technologically accessible, economically feasible, and culturally acceptable. MP Board exams allocate 5–7 marks to this chapter, usually through long-answer questions on resource classification, land use patterns, soil types, and resource conservation methods.

🌍 1. Types of Resources — Classification
A resource is defined as anything available in the environment that can be used to satisfy human needs, provided it is technologically accessible, economically feasible, and culturally acceptable. Resources can be classified in four different ways:
📌 A. On the Basis of Origin
📌 B. On the Basis of Exhaustibility
📌 C. On the Basis of Ownership
📌 D. On the Basis of Status of Development
- Potential Resources: Available but not yet used (e.g., solar/wind energy in Rajasthan and Gujarat)
- Developed Resources: Already surveyed, quantified, and utilised (e.g., coal in Jharia, petroleum in Assam)
- Stock Resources: Known to exist but cannot be used with current technology (e.g., hydrogen in water)
- Reserve Resources: Subset of stock that can be used with existing technology but is set aside for future use (e.g., water in dams for irrigation)
⚡ 2. Development of Resources — Problems and Solutions
Indiscriminate use of natural resources over the past century has created several serious problems:
- Depletion of Resources: Excessive use has exhausted many non-renewable resources.
- Ecological Crisis: Global warming, ozone layer depletion, pollution, land degradation.
- Inequitable Distribution: Rich nations consume disproportionate share; poor communities suffer scarcity.
- Resource Conflicts: Many national and international conflicts arise from competition over resources.
📘 Key Fact: The Rio de Janeiro Earth Summit (1992) was the first major international conference to declare that “resources are not only for the present generation, but also for future generations.” India was a signatory, committing to the principles of sustainable development.
♻️ 3. Sustainable Development
Sustainable development is defined as development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs. It was first popularised by the Brundtland Commission Report (1987) titled “Our Common Future.”
🏞️ 4. Land Resources — Land Utilisation
Land is one of the most important natural resources. India has a total geographical area of about 3.28 million sq. km. Land is used for various purposes:
🗺️ 5. Land Use Pattern in India
The land use pattern in India is influenced by physical factors (climate, soil, topography) and human factors (population density, technology, culture). Important observations:
- Forest cover is far below the desired 33% of geographical area as per National Forest Policy (1952).
- Net sown area has increased over time due to expansion of agriculture — but has stabilised now.
- Land under non-agricultural use is increasing due to urbanisation, industrialisation, and infrastructure development.
- Wasteland includes rocky/arid areas, and degraded land that requires reclamation.
⚠️ 6. Land Degradation and Conservation Measures
Causes of Land Degradation
- Deforestation: Clearing forests for agriculture, settlements, and industry
- Overgrazing: Excessive livestock grazing reduces vegetation cover
- Over-irrigation: Leads to waterlogging and salinisation of soil (especially in Punjab and Haryana)
- Industrial effluents: Chemical waste from factories contaminates land and water
- Mining: Quarrying and mining leaves large tracts of land scarred and unusable
Conservation Measures
🏔️ 7. Soil as a Resource — Classification of Soils
Soil is the uppermost layer of the earth’s crust composed of mineral particles, organic matter, water, air, and living organisms. India has a wide variety of soils due to its diverse climate, geology, and vegetation.
🛡️ 8. Soil Erosion and Soil Conservation
Soil Erosion
Soil erosion is the removal of the top fertile layer of soil by natural agents like wind, water, and ice. It is a serious problem because topsoil formation takes hundreds of years, but erosion can remove it in hours.
Soil Conservation Methods
- Contour Ploughing: Ploughing along contour lines reduces water runoff speed
- Terrace Farming: Building steps on slopes — reduces soil loss in hilly areas
- Strip Cropping: Growing different crops in alternate strips to reduce erosion
- Shelter Belts: Planting rows of trees along coasts or dry areas to block wind
- Afforestation: Planting more trees to hold soil together with roots
- Mulching / Cover Crops: Covering bare soil with crop residue or growing grass cover
📋 9. Previous Year Questions (2017–2026)
❓ Frequently Asked Questions (FAQ)
Q1. What is the difference between Khadar and Bangar soils?
Khadar is new alluvium deposited by rivers every year — lighter in colour, more fertile. Bangar is old alluvium — darker, contains calcareous concretions (kankars), less fertile. Khadar is found closer to river beds, while Bangar is found on uplands.
Q2. Why is black soil ideal for growing cotton?
Black soil (regur) has high moisture-retention capacity, is clayey and deep, and when wet becomes sticky — ideal for cotton’s root system. It also contains calcium carbonate, potash, and lime which cotton requires.
Q3. What is meant by the concept of ‘resource planning’?
Resource planning is a strategy for judicious use of resources. It involves: (a) identification and inventory of resources, (b) planning with appropriate technology and institutions, (c) matching resource development with national development plans. India has a well-established resource planning system.
Q4. Which resources are called ‘stock’ and which are ‘reserves’?
Stock resources are those known to exist but cannot be used with current technology (e.g., hydrogen in water, vast quantities of water in oceans). Reserve resources are a subset of stock that can be used with existing technology but are set aside for future use (e.g., dammed water for irrigation).
Q5. What are the main features of the Rio Earth Summit 1992?
The Rio Earth Summit (1992) was the UN Conference on Environment and Development. Key outcomes: (a) Agenda 21 — global action plan for sustainable development, (b) Forest Principles, (c) Convention on Biological Diversity, (d) Framework Convention on Climate Change (UNFCCC).
Q6. What is gully erosion? Where is it prominent in India?
Gully erosion occurs when running water cuts deep channels into the soil. If unchecked, gullies deepen and widen, turning fertile land into badlands. In India, the Chambal River basin (Madhya Pradesh, Rajasthan, Uttar Pradesh) is the most prominent area affected by gully erosion — known as the Chambal ravines.
Q7. How does over-irrigation cause land degradation?
Excessive irrigation without proper drainage leads to waterlogging and salinisation. Water accumulates below the surface, raising the water table. When this water evaporates, salts are left behind in the upper soil layers, making it unfit for agriculture. This is a major problem in Punjab and Haryana.
Q8. What is the difference between Potential and Developed resources?
Potential resources exist but are not yet used due to lack of technology or investment (e.g., solar energy in Rajasthan). Developed resources have been surveyed, their quantity and quality determined, and are currently being utilised (e.g., petroleum in Assam’s Digboi oil fields).
Q9. Name the soils found in Madhya Pradesh. Which crops are grown there?
Madhya Pradesh has predominantly black soil (regur) in Malwa region, red-yellow soil in Bundelkhand, and alluvial soil along river plains (Narmada, Tapti). Major crops: wheat, soybean, cotton, gram, jowar, pulses, and oilseeds. MP is known as the ‘Soya State’ for its high soybean production.
Q10. Why should resources be used sustainably?
Resources should be used sustainably because many resources (especially non-renewable) take millions of years to form but are being depleted rapidly. The Brundtland Commission report emphasised intergenerational equity — future generations have an equal right to resources. Unsustainable use leads to environmental crises like global warming, pollution, and resource wars.
