Class 10 : Social Science (In English) Geography- Lesson 6. Resources and Development

EXPLANATION & SUMMARY


Resources are materials available in our environment that can satisfy human needs, provided they are technologically accessible, economically feasible, and culturally acceptable. The transformation of environmental materials into resources involves an interactive relationship between nature, technology, and institutions. Human beings play a crucial role as they transform natural materials into valuable resources through innovation and technological advancement.

Classification of Resources
Resources can be systematically classified based on four main criteria:

Based on Origin:

Biotic Resources: Derived from living organisms or organic matter, including forests, wildlife, and agricultural products

Abiotic Resources: Composed of non-living materials such as minerals, rocks, water, and soil

Based on Exhaustibility:

Renewable Resources: Can be replenished naturally over time, like solar energy, wind, and water

Non-renewable Resources: Take millions of years to form and are finite in nature, including fossil fuels and minerals

Based on Ownership:

Individual, community, national, and international resources

Based on Development Status:

Potential, developed, stock, and reserve resources

Development of Resources and Sustainable Development
Indiscriminate use of resources has led to several critical problems including resource depletion, unequal distribution creating socio-economic disparities, and global ecological crises such as climate change and environmental pollution. This necessitates sustainable development, which means meeting present needs without compromising future generations’ ability to meet their needs.

The Rio de Janeiro Earth Summit of 1992 was a landmark event where world leaders signed declarations on climate change and biological diversity, endorsing Agenda 21 for achieving sustainable development in the 21st century. Mahatma Gandhi’s philosophy of resource conservation is particularly relevant, emphasizing that “there is enough for everybody’s need and not for anybody’s greed”.

Resource Planning in India
Resource planning is essential for India due to its enormous diversity in resource availability. Some regions are resource-rich but economically backward, while others have poor resource bases but are economically developed. For example, Jharkhand, Chhattisgarh, and Madhya Pradesh are rich in minerals but lack infrastructure, while Rajasthan has abundant solar and wind energy but faces water scarcity.

Resource planning involves three complex steps: identification and inventory of resources through surveying and mapping, evolving appropriate planning structures with technology and institutional setup, and matching resource development plans with national development objectives. India has pursued these goals systematically since the First Five Year Plan.

Land Resources and Utilization
Land is a finite natural resource supporting vegetation, wildlife, human life, and economic activities. India’s total geographical area is 3.28 million square kilometers, with 43% plains suitable for agriculture and industry, 30% mountains ensuring water flow and tourism, and 27% plateau regions rich in minerals and forests.

Land utilization in India includes forests (23.3%), net sown area (45.5%), barren land, non-agricultural uses, fallow lands, and permanent pastures. The forest area remains significantly below the desired 33% outlined in the National Forest Policy.

Soil as a Resource
Soil is a vital renewable resource that takes millions of years to form. India has diverse soil types based on relief, climate, and vegetation. The major soil classifications include:

Alluvial Soils: Most widespread and fertile, covering northern plains and river deltas, rich in potash and phosphoric acid, ideal for cereal crops.

Black Soils: Known as regur soils, ideal for cotton cultivation, found in Deccan plateau regions, excellent moisture retention capacity.

Red and Yellow Soils: Develop on crystalline rocks in low rainfall areas, found in eastern and southern Deccan plateau.

Laterite Soils: Form under tropical climate with intense leaching, suitable for tea and coffee in hilly areas.

Arid Soils: Sandy and saline, found in dry regions, become cultivable with proper irrigation.

Land Degradation and Conservation
Land degradation affects 95% of our basic needs for food, shelter, and clothing. Major causes include deforestation, overgrazing, mining, over-irrigation, and industrial pollution. Different regions face specific challenges: mining-induced degradation in Jharkhand and Odisha, overgrazing in Gujarat and Rajasthan, and waterlogging in Punjab and Haryana.

Conservation measures include afforestation, proper grazing management, contour ploughing, terrace cultivation, strip cropping, and shelter belt plantation. These methods help prevent soil erosion, stabilize sand dunes, and maintain ecological balance for sustainable resource management.

QUESTIONS FROM TEXTBOOK


Exercise 1: Multiple Choice Questions
Question 1(i): Which one of the following is the main cause of land degradation in Punjab?
(a) Intensive cultivation
(b) Deforestation
(c) Over irrigation
(d) Overgrazing

Answer: (c) Over irrigation

Over irrigation in Punjab has led to waterlogging problems, which increases soil salinity and alkalinity levels. This excessive water usage disrupts the natural soil chemistry and makes the land less productive for agricultural purposes. The state’s intensive farming practices combined with poor drainage systems have created conditions where excess water cannot be properly managed, leading to permanent damage to soil structure and fertility.

Question 1(ii): In which one of the following states is terrace cultivation practised?
(a) Punjab
(b) Plains of Uttar Pradesh
(c) Haryana
(d) Uttarakhand

Answer: (d) Uttarakhand

Terrace cultivation is primarily practiced in Uttarakhand due to its hilly and mountainous terrain. This agricultural technique involves creating step-like flat areas on slopes to prevent soil erosion and facilitate farming on steep hillsides. The western and central Himalayan regions, including Uttarakhand, have well-developed terrace farming systems that help conserve soil and water while making cultivation possible on otherwise unusable sloped land.

Question 1(iii): In which of the following states black soil is predominantly found?
(a) Uttar Pradesh
(b) Maharashtra
(c) Rajasthan
(d) Jharkhand

Answer: (b) Maharashtra

Black soil, also known as regur soil or black cotton soil, is predominantly found in Maharashtra. This soil type is formed from the weathering of basaltic lava flows in the Deccan trap region. Maharashtra’s plateau areas contain extensive deposits of this fertile soil, which is particularly suitable for cotton cultivation due to its high moisture retention capacity and rich mineral content including calcium carbonate, magnesium, and potash.

Exercise 2: Short Answer Questions (30 words each)
Question 2(i): Name three states having black soil and the crop which is mainly grown in it.

Answer: The three states having black soil are Maharashtra, Madhya Pradesh, and Chhattisgarh. Cotton is the main crop grown in black soil due to its excellent moisture retention properties and high fertility. Black soil’s clayey nature and rich mineral content make it ideal for cotton cultivation, which requires consistent moisture levels throughout its growing period.

Question 2(ii): What type of soil is found in the river deltas of the eastern coast? Give three main features of this type of soil.

Answer: Alluvial soil is found in the river deltas of the eastern coast. Three main features are: First, it is extremely fertile and suitable for intensive agriculture. Second, it contains adequate proportions of potash, phosphoric acid, and lime essential for crop growth. Third, it has excellent water retention capacity and consists of fine particles that support diverse cereal and pulse crops effectively.

Question 2(iii): What steps can be taken to control soil erosion in the hilly areas?

Answer: Soil erosion in hilly areas can be controlled through terrace cultivation, which creates flat surfaces on slopes to prevent water runoff. Contour ploughing along slope lines reduces water flow velocity. Strip cropping involves growing grass strips between crops to break wind force. Afforestation and planting shelter belts help stabilize soil and reduce erosion caused by wind and water action.

Exercise 3: Long Answer Questions (120 words each)
Question 3(i): Explain land use pattern in India and why has the land under forest not increased much since 1960-61?

Answer: India’s land use pattern is determined by both physical factors like topography, climate, and soil types, and human factors including population density, technological capability, and cultural traditions. The country’s total geographical area of 3.28 million square kilometers is utilized for various purposes including forests, agricultural land, settlements, and industrial activities.

The net sown area varies significantly across states, being over 80 percent in Punjab and Haryana but less than 10 percent in northeastern states like Arunachal Pradesh and Mizoram. Currently, India’s forest cover remains far below the desired 33 percent outlined in the National Forest Policy of 1952, which is considered essential for maintaining ecological balance.

Forest land has not increased substantially since 1960-61 due to several factors. Growing population pressure has led to conversion of forest land for agricultural expansion, settlements, and infrastructure development. Industrial growth has required land for factories, mining activities, and transportation networks. Additionally, the livelihood needs of millions of people living on forest fringes have resulted in encroachment and degradation of forest areas, making forest conservation and expansion challenging despite policy initiatives.

Question 3(ii): How have technical and economic development led to more consumption of resources?

Answer: Technical and economic development have significantly increased resource consumption through various interconnected mechanisms. Large-scale industrialization has created mass production systems that require enormous quantities of raw materials, energy, and natural resources to meet growing market demands and consumer expectations.

Technological advancement has enabled greater exploitation of previously inaccessible resources through improved extraction techniques, machinery, and processing methods. This has made resource utilization more efficient but also more intensive, leading to faster depletion of available reserves. Advanced technology has also created new products and services that require additional resource inputs.

Economic growth has improved living standards and increased purchasing power, leading to higher consumer demand for goods and services. Urban lifestyle changes have promoted consumption patterns that require more processed foods, manufactured goods, and energy-intensive services. The expansion of transportation networks, communication systems, and industrial infrastructure has created additional resource demands.

Furthermore, improved medical and health facilities have led to population growth, which directly correlates with increased resource consumption. The shift from traditional sustainable practices to modern consumption-oriented lifestyles has disrupted the natural balance between resource availability and human needs, creating unprecedented pressure on natural resources globally.
