1
A 'resource' is anything available in our environment that can be used to satisfy human needs, provided it is technologically accessible, economically feasible, and culturally acceptable. Resources are not free gifts of nature; they are a result of human activities, involving an interactive relationship between nature, technology, and institutions.
2
Biotic resources are living things, such as plants and animals (e.g., forests, fisheries). Abiotic resources are non-living things, such as rocks and metals (e.g., land, water, minerals).
3
Renewable resources can be replenished by natural processes within a relatively short period. Examples include solar energy and wind energy. Non-renewable resources exist in limited quantities and take millions of years to form, so they are exhaustible. Examples include coal and petroleum. Sustainable use is crucial to prevent their depletion for future generations.
4
Resources can be classified based on ownership as: Individual Resources (owned by private individuals, e.g., a plot of land owned by a farmer), Community Resources (owned by all members of a community, e.g., common grazing grounds), National Resources (belonging to a nation, e.g., minerals, railways), and International Resources (regulated by international institutions, e.g., oceans beyond 200 nautical miles).
5
Resources are classified based on their status of development into: Potential Resources (found in a region but not yet utilized, e.g., solar energy in Rajasthan), Developed Resources (surveyed, quality and quantity determined, and being used, e.g., coal), Stock (can be used to satisfy needs but lack technology for utilization, e.g., hydrogen as a potential energy source), and Reserves (subset of stock that can be put to use with the help of existing technology, e.g., forests).
6
The village has potential resources, specifically abundant water resources. The challenges in development include the lack of technological accessibility (e.g., for hydropower generation) and insufficient infrastructural development (e.g., roads, electricity grids). Overcoming these would require investment in technology and infrastructure, and possibly community participation and government support.
7
The statement implies that human beings are integral to the creation and utilization of resources. They possess knowledge, technology, and skills to transform materials found in the environment into useful resources. Their efforts, decisions, and actions directly influence the availability and management of resources.
8
Indiscriminate exploitation of resources has led to: depletion of resources to satisfy greed, accumulation of resources in the hands of a few leading to societal division (haves and have-nots), and global ecological crises like global warming, ozone layer depletion, and environmental pollution.
9
Sustainable Development is defined as 'development that takes place without damaging the environment, and development in the present should not compromise the needs of the future generations.' The Rio de Janeiro Earth Summit, 1992, was convened to address urgent environmental protection and socio-economic development issues globally, leading to the adoption of Agenda 21 for achieving sustainable development.
10
'Agenda 21' is a declaration signed by world leaders in 1992 at the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro. Its primary objective is to achieve global sustainable development by combating environmental damage, poverty, and disease through global cooperation on common interests, mutual needs, and shared responsibilities.
11
Resource planning is crucial in India due to vast disparities in resource availability. For example, Jharkhand, Chhattisgarh, and Madhya Pradesh are rich in minerals and coal, while Arunachal Pradesh has abundant water resources but lacks infrastructure. Rajasthan is rich in solar and wind energy but short of water. Such imbalances necessitate planned development to ensure equitable access.
12
Resource planning in India involves: (i) Identification, inventory, and qualitative/quantitative assessment of available resources through surveying and mapping. (ii) Developing a planning structure with appropriate technology, skills, and institutions for implementing resource development plans. (iii) Aligning resource development plans with overall national development plans.
13
Technological advancements enable the exploitation of new resources (e.g., deep-sea minerals, unconventional energy sources) and facilitate mass production. Economic development leads to increased purchasing power, driving higher demand and consumption of resources to satisfy a wider range of needs and desires.
14
Land degradation is caused by: Human Activities such as deforestation, over-grazing, mining, quarrying, excessive irrigation (waterlogging and salinity), and industrial effluent disposal. Natural Factors include processes like wind and water erosion, which can be exacerbated by human activities.
15
Three measures for conserving land resources are: (i) Afforestation and proper management of grazing lands. (ii) Planting shelter belts of plants and stabilizing sand dunes in arid areas. (iii) Controlling mining activities and proper treatment and disposal of industrial effluents and wastes.
16
Soil is formed through the process of weathering of bed rock and accumulation of organic matter. Key factors influencing soil formation include: Relief (topography), Parent rock (determines mineral composition), Climate (temperature, rainfall affect weathering), Vegetation, and Time (takes millions of years for soil to form). Forces of nature like running water, wind, and glaciers also contribute.
17
Black soil, also known as 'regur' or 'black cotton soil', is black in colour and made up of fine clayey material. It has excellent moisture-holding capacity and is rich in calcium carbonate, magnesium, and potash. It is ideal for growing cotton and develops deep cracks in hot weather for aeration.
18
Alluvial soils are widely spread across the northern plains of India, formed by the Indus, Ganga, and Brahmaputra river systems. They are also found in coastal plains and deltas. These soils consist of varying proportions of sand, silt, and clay. They are generally fertile, rich in potash, phosphoric acid, and lime, making them ideal for various crops like sugarcane, paddy, and wheat.
19
The region's potential for solar and wind energy (a potential resource) is high, but its scarcity of water (a limiting factor) hinders development. Balanced resource planning would involve investing in technologies for water conservation and management (e.g., rainwater harvesting, efficient irrigation), alongside developing the renewable energy sector. This balanced approach would ensure sustainable development by leveraging available resources while addressing limitations.

Bangar soil is the older alluvial soil found in the higher reaches of river valleys, characterized by a higher concentration of 'kanker' (calcareous nodules) and coarser particles. Khadar soil is the newer alluvial soil, found in the lower reaches and floodplains, with finer particles and a higher fertility due to fresh silt deposits.
