Geo - ch- Resources and development Notes taught till 22/04/20

Everything available in the environment which can be used to satisfy our needs provided it is technologically accessible, economically feasible, and culturally acceptable can be termed as Resource.

Types of Resources:

Resources can be classified on different bases; into following types:

a.    On the basis of origin: Biotic and Abiotic

b.    On the basis of exhaustibility: Renewable and Non-renewable

c.    On the basis of ownership: Individual, community, national and international

d.    On the basis of status of development: Potential, Developed, Stock and Reserves

Classification of Resources : On the basis of Origin

1. Biotic Resources: All living organisms in our environment are called biotic resources. For example, trees, animals, insects, etc.
2. Abiotic Resources: All non-living things present in our environment are termed as abiotic resources. For example – earth, air, water, metals, rocks, etc.

Classification of Resources: On the basis of Exhaustibility:

1. Renewable Resources: Resources that can be replenished after a short period of time are called Renewable Resources. For example – agricultural crops, water, forest, wildlife, etc.
2. Non-renewable Resources: Resources which takes million years of time to replenish are called non-renewable resources. For example – fossil fuel.

Classification of Resources: On the Basis of ownership:

1. Individual: Resources owned by individuals are called Individual Resources. For example – land owned by farmers, house, etc.
2. Community: Resources owned by community or society are called Community Owned Resources. For example – Graveyard, grazing land, ponds, burial grounds, park, etc.
3. National Resources: Resources owned by Individual Nations are called National Resources. For example – Government land, Roads, canals, railway, etc.
4. International Resources: Resources regulate by International bodies are called International Resources. For example – Ocean and sea beyond 200 km of the Exclusive Economic Zone and is called open sea or ocean. No individual country can utilize these resources without the permission of International bodies.

Classification of Resources: On the basis of Status of Development:

1. Potential Resources: Resources which are found in a particular region, but not yet used properly. For example – Rajasthan and Gujarat receive plenty of solar energy and have plenty of wind energy, but use of these resources so far has not been developed properly.
2. Developed Resources: Resources which are developed and surveyed for utilization and are being used in present time are known as Developed Resources.
3. Stock: Resources that are available, but we do not have proper technology to used them are called Stock. For example – water is made of oxygen and hydrogen, which can be used as fuel, but because of lack of proper technology these are not being used.
4. Reserves: Resources which are available and the knowhow to use them is also present but they are yet to be used are called Reserves. For example – river water which is not used to generate electricit

Discriminate use of Resources

Resources are vital for human beings. But indiscriminate use of resources is creating many  problems.

Examples:

• Accumulation of resources in only few hands leaves others unsatisfied.
• Indiscriminate use of resources is creating many problems around the world, such as global warming, ecological crisis, disturbance in ozone layer, etc.
• Thus, equal distribution of resources becomes necessary for sustainable development.

Sustainable Development: Development which takes place without damaging the environment and compromising with needs of future is called sustainable development.

Keeping the view of justified use of resources and sustainable development, the Earth Summit was organized in 1992 in Rio de Janeiro in which more than 100 state heads agreed with Agenda 21 for the sustainable development and proper use of resources.

Agenda 21 is an agenda to combat environmental damage, poverty, disease, etc. through global co-operation on common interests, mutual needs and shared responsibilities.

Resource Planning:

Resource planning is the judicious use of resources. Resource planning becomes more important in a country like India, where resources are not distributed properly. For example; many states are rich in mineral and deficient in other resources, such as Jharkhand is rich in minerals, but there is problem of drinking water and other facilities, Arunachal Pradesh has plenty of water but lack of other development because of lack of resources.

These types of discriminations can be reduced or completely vanished with proper planning of judicious use of resources.

Resource Planning in India:

Resources can contribute in proper development only with a good planning keeping the technology, skills and institution in mind.

Resource Planning in India is one of the most important goals right from its first Five Years Plan. Following are the main points of Resource planning.

1. Making of inventory of resources after their region-wise identification across the country.
2. Making of the planning structure with appropriate technology, skill and institutions.
3. Matching of resource plan with development plan, etc.

Conservation of Resources:

Overuse of resources creates many socio-economic problems. Many leaders and thinkers have been advocating for the judicious use and conservation of resources. Gandhiji told “There is enough for everybody’s need and not for any body’s greed.” He thought that exploitative nature of modern technology is the root cause for depletion at global level. He believed in the production by masses and not in the mass production.

Thus, conservation of resources at various levels becomes most important. Resources can be conserved only with their judicious use.

Land Resources:

Land is one of the most important natural resources. Land supports our life system. Thus, careful planning of use of land resource is necessary. India comprises of many types of land. These are mountains, plateau, plains and islands.

• Mountains: About 30% of land area in India is in the form of mountain. Mountain supports the perennial flow of rivers, which carry fertile soils, facilitate irrigation and provide drinking water.
• Plain: About 43% of land area in India is in the form of plains. Plains provide facilities for agriculture, building of industries and houses, etc.
• Plateau: About 27% of land in India is in the form of plateau which provides many types of minerals, fossil fuels and forest.

Land Utilisaiton: Patterns of use of Land Resources

1. Forests
2. Land not available for cultivation: There are two types of land which are not used for agriculture purpose. These are:
1. Barren and waste land
2. Lands used for buildings, roads, factories, etc. i.e for non-agriculture purpose.
3. Other uncultivated land (excluding fallow land)
1. Permanent pastures and grazing land,
2. Land under miscellaneous tree crops groves (not included in net sown area),
3. Culturable waste land (left uncultivated for more than 5 agricultural years).
4. Fallow lands
1. Current fallow-(left without cultivation for one or less than one agricultural year),
2. Other than current fallow-(left uncultivated for the past 1 to 5 agricultural years).
5. Net sown area: Area which is sown at least once in a year is called net sown area.
6. Gross cropped area: Area sown more than once in an agricultural year plus net sown area is known as gross cropped area.

Land Use Pattern in India:

Pattern of use of land depends upon physical and human factors both. Climate, topography, type of soil, etc. are considered as physical factors while population, technology, skill, population density, tradition, capability, etc. are considered as human factors.

India has total 3.28 million square kilometer land used data. But only 93% of land of total geographical area is available. This is because land used data has not been collected for the north eastern states except Assam and the land occupied by Pakistan and China has not been surveyed because of many unavoidable reasons.

The land under permanent pasture is decreasing, this will create the problem for grazing. The total net sown are (NSA) is not more than 54% including land other than fallow land. Land other than fallow land is either of poor quality or too costly to cultivate, these lands are cultivated only once or twice in two or three consecutive years.

The pattern of net sown area varies widely from state to state. Where net sown area is 80% in state like Punjab, it is only 10% in the state of Arunachal Pradesh, Mizoram, Manipur and Andaman and Nicobar Island. Such difference is creating lot of discrimination.

According to National Forest Policy (1952), the forest should be 33% of total geographical area, which is essential to maintain ecological balance. But the forest area in India is far less than desired measures. This is because of illegal deforestation and development which cannot be overlooked, such as construction of roads and building, etc. On the other hand, a large population which is dwelling at the fringe of forest depends upon the forest and its produce, resulting in the reduction of forest area.

Moreover, continuous use of land over a long period without taking measures to conserve and manage, degrade them. This has resulted in repercussion in society and creating serious problem to environment.

Land as Resource

Our past generation left land for us without exploiting them too much and it is expected from us too. We fulfill most of our needs from land, such as food, clothing, shelter, drinking water, etc. But in past few decades the quality of land is degrading fiercely because of human activity. Many human activities aggravated the natural forces which are, in turn, degrading the land resources also.

Presently, about 130 million hectare of land is reported under degraded land in India, in which about 28% of land belongs to forest and about 28% is water eroded area. Rest degraded land is because of over deposition of salinity and alkalinity. Overgrazing, mining, deforestation, division of lands in small area because of family feuds, etc. are some of the major causes of degradation of land.

Because of mining in the states of Jharkhand, Chhattisgarh, Orissa and Madhya Pradesh; lands are left abandoned without proper treatment after the completion of mining works. This has resulted in the form of deep scars and traces. Along with mining, deforestation in these states has degraded the land very fast.

In the states of Uttar Pradesh, Punjab, Haryana, over irrigation causes water shortage and increase in salinity and alkalinity due to water logging.

In Bihar, Assam, Arunachal Pradesh, land is degraded because of flood.

States, in which minerals processing, such as grinding of lime stone, manufacturing of cement, etc. produce huge quantity of dust. These dusts prevent the percolation of water because of deposition on the ground and it is responsible for degradation of land.

The degradation of land creates many problems, such as flood, decrease in yield, etc. which leads to decrease in GDP and country has to face economic problems.
