Q
Can you identify and name the various items used in making life comfortable in our villages and towns? List the items and name the material used in their making.

Yes. Some common items are houses, roads, vehicles, farm tools, furniture, cooking utensils, clothes and mobile phones. Houses use materials such as bricks, cement, sand, steel, wood and glass. Roads use stone, sand, bitumen and cement. Vehicles use iron, steel, aluminium, rubber, glass and plastic. Furniture may use wood, steel and plastic. Cooking utensils commonly use steel, aluminium or clay. Clothes use cotton, wool, silk or synthetic fibres. These examples show that materials from nature become useful resources when people use technology and skills to transform them.

MEMORY TRICK

A resource is not simply something found in nature. It must be technologically accessible, economically feasible and culturally acceptable.

Q
Imagine, if the oil supply gets exhausted one day, how would this affect our life style?

If oil were exhausted, transport would be badly affected because petrol, diesel and other petroleum products are widely used in vehicles. Industries would also face difficulties because petroleum is used as a fuel and as a raw material for many products. Farming could become more difficult where machines depend on petroleum fuels. The cost and availability of goods could change because transporting them would become harder. We would need to use alternatives such as electricity, solar energy, wind energy and other renewable sources, and reduce unnecessary consumption.

MEMORY TRICK

Oil is a non-renewable resource, so it forms much more slowly than people consume it.

Q
Plan a survey in your colony/village to investigate people's attitude towards recycling of the domestic/agricultural wastes. Ask questions about: (a) What do they think about resources they use? (b) What is their opinion about the wastes, and its utilisation? (c) Collage your results.

A simple survey can be conducted by asking 10–20 families the same questions. Record whether they separate wet and dry waste, reuse materials, recycle paper, plastic or metal, and use agricultural waste such as crop residue or animal waste. Ask whether they think resources should be conserved and whether waste can be useful. Put the answers in a table and prepare a collage using photographs, drawings or short statements. The results can then be displayed in the class to compare people's habits and opinions.

MEMORY TRICK

Separating waste at the source makes recycling and safe disposal easier.

Q
Can you name some resource rich but economically backward regions and some resource poor but economically developed regions? Give reasons for such a situation.

Resource-rich but economically backward regions can include parts of Jharkhand, Chhattisgarh and Madhya Pradesh, which have important mineral and coal resources. A region may remain economically backward if it lacks suitable technology, infrastructure, skilled human resources and effective institutions. In contrast, some resource-poor regions can become economically developed through better technology, infrastructure, human skills, institutions and services. Therefore, natural resources alone do not guarantee economic development. Their development depends on how effectively people, technology and institutions use them.

MEMORY TRICK

The chapter explains that resource development depends not only on the availability of resources but also on technology, human resources and historical experiences.

Q
What resources are being developed in your surroundings by the community/village panchayats/ward level communities with the help of community participation?

Possible examples include drinking-water facilities, ponds, roads, drainage systems, community forests, waste-management facilities, playgrounds and local irrigation facilities. The exact examples depend on the locality. Community participation may include providing labour, helping in planning, protecting common resources and contributing to maintenance. Such work shows that local people and institutions can help develop and conserve resources according to local needs.

MEMORY TRICK

Community participation is important because local people usually understand the condition and needs of their surroundings directly.

Q
Prepare a list of resources found in your state and also identify the resources that are important but deficit in your state.

For Assam, examples of important resources include fertile alluvial soils, water resources, forests, petroleum and natural gas, tea-growing land and biodiversity. Resources that may be deficient in particular areas include suitable infrastructure, some minerals and reliable transport or other facilities. The exact list can vary from one district to another. The main idea is to compare resources that are available with resources that are needed but insufficient.

MEMORY TRICK

Resource availability can vary greatly from one region of a state to another.

Q
Find out reasons for the low proportion of net sown area in Arunachal Pradesh, Mizoram, Manipur and Andaman and Nicobar Islands.

The low net sown area in these regions is linked mainly to their physical conditions. Much of Arunachal Pradesh, Mizoram and Manipur is hilly or mountainous, which limits the availability of level agricultural land. Forest cover is also extensive in many areas. In the Andaman and Nicobar Islands, the island environment, forest cover and limited cultivable land restrict the net sown area. Therefore, the proportion of land suitable and available for regular cultivation is relatively low.

MEMORY TRICK

Net sown area means the physical extent of land on which crops are sown and harvested.

Q
Try to do a comparison between the two pie charts (Fig. 1.4) given for land use and find out why the net sown area and the land under forests have changed from 1960-61 to 2019-20 very marginally.

The two pie charts show that the overall shares of net sown area and forest area changed only moderately between 1960-61 and 2019-20. India has a fixed geographical area, while land is required for agriculture, forests, settlements, roads, industries and other uses. Increasing population and development create pressure on land, while forest conservation policies also limit the conversion of forest land. At the same time, only a limited amount of land is physically suitable for cultivation. These factors help explain why the shares of major land-use categories have not changed dramatically.

MEMORY TRICK

The chapter states that land use is controlled by both physical factors, such as topography and climate, and human factors, such as population density and technology.

Q
The land under permanent pasture has also decreased. How are we able to feed our huge cattle population on this pasture land and what are the consequences of it?

A smaller area of permanent pasture means that the cattle population has to depend more on other sources of fodder, such as crop residues, cultivated fodder and other grazing areas. Excessive pressure on the remaining pasture can cause overgrazing. Overgrazing removes vegetation cover and exposes the soil to erosion and degradation. It can also reduce the productivity of grazing land and put pressure on other land resources.

MEMORY TRICK

Overgrazing is identified in the chapter as an important cause of land degradation in parts of Gujarat, Rajasthan, Madhya Pradesh and Maharashtra.

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

The correct answer is (c) Over irrigation. In Punjab, Haryana and western Uttar Pradesh, over-irrigation can cause water logging, which increases salinity and alkalinity in the soil and contributes to land degradation.

MEMORY TRICK

Remember: Punjab + Haryana + western Uttar Pradesh → over-irrigation → water logging → salinity/alkalinity.

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

The correct answer is (d) Uttarakhand. Terrace cultivation is practised on slopes by cutting steps into the land. The chapter also notes well-developed terrace farming in the western and central Himalayas.

MEMORY TRICK

Terraces slow down the flow of water on slopes and therefore help control soil erosion.

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

The correct answer is (b) Maharashtra. Black soil is widespread in the Deccan Plateau and covers large areas of Maharashtra. It is also known as regur or black cotton soil.

MEMORY TRICK

Black soil is strongly associated with cotton cultivation.

Exercise — Answer in About 30 Words
Q
Name three states having black soil and the crop which is mainly grown in it.

Maharashtra, Madhya Pradesh and Gujarat have large areas of black soil. Cotton is the main crop associated with black soil because the soil retains moisture well and is suitable for cotton cultivation.

MEMORY TRICK

Black soil is also rich in nutrients such as calcium carbonate, magnesium, potash and lime.

Q
What type of soil is found in the river deltas of the eastern coast? Give three main features of this type of soil.

Alluvial soil is found in the river deltas of the eastern coast. It is very fertile, contains sand, silt and clay, and generally has useful amounts of potash, phosphoric acid and lime.

MEMORY TRICK

Important eastern-coast deltas mentioned in the chapter include the Mahanadi, Godavari, Krishna and Kaveri deltas.

Q
What steps can be taken to control soil erosion in the hilly areas?

Contour ploughing, terrace cultivation and planting trees can control soil erosion in hilly areas. These methods slow down water flow, hold soil on slopes and reduce the removal of topsoil.

MEMORY TRICK

A quick memory trick: Hilly areas → Contour + Terraces + Trees.

Q
Explain land use pattern in India and why has the land under forest not increased much since 1960-61?

Land in India is used for forests, land not available for cultivation, other uncultivated land, fallow land and net sown area. Land not available for cultivation includes barren and waste land and land used for buildings, roads and factories. Other uncultivated land includes permanent pastures, tree crops and culturable waste. Fallow land is land left uncultivated for a limited period, while net sown area is the land on which crops are sown and harvested. Land use is influenced by relief, climate, soil, population density, technology, culture and traditions. Forest area has not increased much because land is also required for agriculture, settlements, infrastructure and other economic activities. At the same time, forests are important for ecological balance and livelihoods, so conservation also limits their conversion.

MEMORY TRICK

The chapter notes that the desired forest cover under the National Forest Policy (1952) was 33 per cent of geographical area.

Q
How have technical and economic development led to more consumption of resources?

Technical and economic development increase people's ability to extract, process and use natural resources. Better technology makes it possible to exploit resources on a larger scale, while economic development increases production, transport, construction and consumption. As industries expand, they need more minerals, energy, land and water. Growing populations and improved standards of living also increase demand for houses, vehicles, electricity, food and manufactured goods. The chapter explains that indiscriminate exploitation can lead to depletion of resources, concentration of resources in a few hands and environmental problems such as pollution and land degradation. Therefore, development needs resource planning and sustainable use so that present needs are met without damaging the ability of future generations to meet their needs.

MEMORY TRICK

Sustainable development means development in the present without compromising the needs of future generations.

Project/Activity
Q
Make a project showing consumption and conservation of resources in your locality.

A suitable project can record how households, schools and shops use water, electricity, fuel, paper, food and other resources. For each resource, note common uses, sources of wastage and methods of conservation. For example, water can be saved by repairing leaks and reusing suitable water; electricity can be saved by switching off unused appliances; paper can be reduced by using both sides; and waste can be separated for recycling. Add photographs, a short survey, a table of observations and practical suggestions. End the project with a conclusion explaining why careful use of resources is necessary.

MEMORY TRICK

A project becomes stronger when it uses actual observations from the locality instead of only general statements.

Q
Have a discussion in the class – how to conserve various resources used in your school.

Students can discuss water, electricity, paper, food, school furniture, laboratory materials and other resources. Practical measures include closing taps properly, repairing leaks, switching off lights and fans when not needed, reducing unnecessary printing, reusing paper where possible, separating waste and maintaining school property carefully. The class can prepare a short list of actions and decide which ones can be followed regularly.

MEMORY TRICK

Conservation means careful and planned use of resources, not simply avoiding their use.

Q
Imagine if oil supplies get exhausted, how will this affect our life style?

Exhaustion of oil supplies would affect transport, industry, farming and many everyday products. Petrol and diesel vehicles would need alternatives, and transporting goods could become more difficult. Industries that depend on petroleum as fuel or raw material would also have to change their processes. People would need to rely more on alternatives such as electricity, renewable energy and other suitable fuels. Travel and consumption habits could change, and products made from petroleum-based materials could become difficult or costly to obtain.

MEMORY TRICK

Oil is called a non-renewable resource because it takes a very long time to form naturally.

Q

Q
Intensively leached soils of the monsoon climate.

Laterite soil.

MEMORY TRICK

Laterite soil forms under tropical and subtropical climates with alternate wet and dry seasons and heavy rainfall.

Q
Plantation of trees on a large scale to check soil erosion.

Afforestation.

MEMORY TRICK

Afforestation adds vegetation cover, which can help protect soil from erosion.

Q
The Great Plains of India are made up of these soils.

Alluvial soils.

MEMORY TRICK

The northern plains are largely made of alluvial soil deposited by the Indus, Ganga and Brahmaputra river systems.
