Chapter 1: Resources and Development

Answer:
This chapter explains the meaning, classification, planning, development and conservation of resources. It discusses land resources, land use pattern in India, land degradation, soil as a resource, different types of soils, soil erosion and methods of soil conservation. The chapter also emphasises sustainable development and judicious use of resources.

Answer:
Everything available in our environment that can be used to satisfy our needs is called a resource, provided it is technologically accessible, economically feasible and culturally acceptable. Human beings are an important part of resources because they transform things available in nature into useful resources.

Suggested Answer:

Suggested Answer:
If oil supply gets exhausted, transport, industries, agriculture and daily life will be badly affected. Vehicles using petrol and diesel will stop running. Prices of goods will increase because transportation will become difficult. Many industries that depend on petroleum products will suffer. Farmers may face problems in running tractors, pumps and machines. People will have to depend more on renewable energy, public transport, electric vehicles, cycling and local production.

Suggested Survey Format:
Conclusion: Recycling reduces pollution, saves resources and promotes sustainable development. People need awareness and proper waste collection facilities.

Suggested Answer:
Resource-rich but economically backward regions: Jharkhand, Chhattisgarh, Odisha and parts of Madhya Pradesh are rich in minerals, coal and forests but many areas remain economically backward because of poor infrastructure, low industrial development, poverty, displacement and lack of human resource development.

Resource-poor but economically developed regions: Delhi, Haryana, Gujarat and parts of Maharashtra have developed economically due to better infrastructure, industries, technology, investment, markets, transport and skilled human resources.

Reason: Availability of resources alone does not guarantee development. Technology, institutions, planning, investment and skilled people are also necessary.

Answer: (c) Over irrigation

Explanation: In Punjab, over-irrigation has caused waterlogging, which increases salinity and alkalinity in the soil. This leads to land degradation.

Answer: (d) Uttarakhand

Explanation: Terrace cultivation is practised in hilly areas. Uttarakhand lies in the Himalayan region, where slopes are cut into terraces to reduce soil erosion and support farming.

Answer: (b) Maharashtra

Explanation: Black soil is common in the Deccan Trap region and is found extensively in Maharashtra. It is ideal for growing cotton.

Answer:
Three states having black soil are Maharashtra, Madhya Pradesh and Gujarat. Black soil is also found in parts of Chhattisgarh and Karnataka. The crop mainly grown in black soil is cotton, because this soil retains moisture well.

Answer:
Alluvial soil is found in the river deltas of the eastern coast, such as the Mahanadi, Godavari, Krishna and Kaveri deltas.

Three features:
1. It is very fertile.
2. It contains sand, silt and clay in different proportions.
3. It is rich in potash, phosphoric acid and lime, and supports crops like paddy, sugarcane and wheat.

Answer:
Soil erosion in hilly areas can be controlled by terrace cultivation, contour ploughing, afforestation, controlled grazing and proper land management. Terraces reduce the speed of water flow, while trees hold the soil with their roots and prevent washing away of the topsoil.

Answer:
Land in India is used for different purposes such as forests, land not available for cultivation, permanent pastures, grazing land, land under miscellaneous tree crops, culturable waste land, fallow land and net sown area. Net sown area is the land on which crops are grown and harvested. Land use pattern is influenced by physical factors like relief, climate and soil, and human factors like population density, technology, culture and traditions.

The land under forest has not increased much since 1960–61 because of the expansion of agriculture, settlements, industries, roads, railways, mining and other development activities. Population pressure and encroachment have also reduced the possibility of expanding forests. As a result, India’s forest area remains below the desired 33 per cent of the geographical area needed for ecological balance.

Answer:
Technical and economic development have increased the consumption of resources in many ways. Improved technology makes it easier to extract, process and transport resources on a large scale. Industrialisation increases the demand for minerals, energy, water, land and raw materials. Urbanisation increases the need for housing, roads, electricity, transport and consumer goods. Rising incomes and modern lifestyles also increase the demand for vehicles, electronic goods, packaged products and energy.

Economic development creates more factories, markets and infrastructure, which require huge quantities of natural resources. However, if resources are used carelessly, it leads to depletion, pollution, land degradation and ecological imbalance. Therefore, technical and economic development must be combined with resource planning and sustainable development.

Answer:
Resource planning is necessary because resources are not distributed equally. Some regions are rich in certain resources but poor in others. Indiscriminate use of resources causes depletion, inequality and environmental problems such as global warming, ozone layer depletion, pollution and land degradation. Resource planning helps in balanced development and ensures that resources are used judiciously for present and future generations.

Answer:
Sustainable development means development that takes place without damaging the environment and without compromising the needs of future generations. It aims to balance economic growth, environmental protection and social equity. Sustainable development encourages conservation, recycling, renewable energy, responsible consumption and fair distribution of resources.

Answer:

Answer:
Land is an important natural resource because human beings perform most economic activities on land. It supports agriculture, forests, wildlife, settlements, industries, transport and communication. Land is limited in quantity, so it must be used carefully. India has plains, mountains, plateaus and islands, and each relief feature supports different economic and ecological functions.

Answer:

Answer:
Soil erosion is the removal or washing away of the top layer of soil by natural forces such as running water, wind, glaciers and human activities like deforestation, overgrazing, mining and faulty farming methods.

Sample Project:

Title: Consumption and Conservation of Resources in My Locality

Resources commonly used: Water, electricity, petrol, cooking gas, paper, plastic, vegetables, building materials and soil.

Problems observed: Wastage of water, excessive use of plastic, high electricity consumption, improper waste disposal and low awareness about recycling.

Conservation measures:
1. Use rainwater harvesting.
2. Switch off lights and fans when not needed.
3. Use public transport, walking or cycling for short distances.
4. Segregate dry and wet waste.
5. Compost kitchen waste.
6. Plant trees and protect green areas.
7. Avoid single-use plastic.

Conclusion: Resource conservation should begin at the local level. Small actions by households, schools and communities can reduce waste and protect the environment.

Suggested Points:
1. Switch off lights, fans and projectors after use.
2. Use both sides of paper.
3. Avoid wasting drinking water.
4. Repair leaking taps immediately.
5. Use dustbins for waste segregation.
6. Reuse chart papers, files and decorations.
7. Plant trees and maintain the school garden.
8. Conduct awareness campaigns on resource conservation.
