Key Concepts
What are Resources?
Anything that can be used to satisfy a need is a resource. Resources have value, and value means worth. Some resources have economic value (like minerals), some have aesthetic value (like a beautiful landscape), while others have cultural or sentimental value.
Technology and human ingenuity turn substances into resources. For example, rivers were just water bodies until humans learnt to harness them for irrigation and hydroelectric power.
Types of Resources
Based on Origin:
Biotic Resources: Obtained from the biosphere and have life. Examples: forests, animals, fish, livestock, human beings.
Abiotic Resources: Composed of non-living things. Examples: rocks, metals, minerals, land, water, air.
Based on Exhaustibility:
Renewable Resources: Resources that can be replenished naturally over time. Examples: solar energy, wind energy, water, forests (if managed sustainably).
Non-Renewable Resources: Resources that take millions of years to form and cannot be replaced once exhausted. Examples: coal, petroleum, natural gas, minerals.
Based on Ownership:
Individual Resources: Owned by individuals, such as private land, houses, plantations.
Community Resources: Accessible to all members of a community, such as parks, playgrounds, burial grounds.
National Resources: All resources within the political boundaries of a nation belong to the nation. Examples: roads, railways, minerals, water bodies, forests.
International Resources: Resources beyond 200 nautical miles of the Exclusive Economic Zone belong to the international community. No single country can use these without international agreement.
Based on Development Status:
Actual Resources: Resources whose quantity is known and are being used currently. Example: coal deposits in Jharia.
Potential Resources: Resources whose entire quantity is not known and are not being used at present. Example: uranium in Ladakh.
Sustainable Development
Sustainable development means using resources carefully so that they last for present as well as future generations. Balancing economic growth with environmental protection is the key idea. The concept was highlighted in the Brundtland Commission Report (1987), also known as "Our Common Future".
Resource Conservation
Using resources carefully and giving them time to get renewed is called resource conservation. Mahatma Gandhi said: "There is enough for everybody's need but not for anybody's greed." This principle underpins conservation.
Summary
Resources are substances that satisfy human needs and have value. They are classified by origin (biotic/abiotic), exhaustibility (renewable/non-renewable), ownership (individual/community/national/international), and development status (actual/potential). Sustainable development ensures resources are available for both present and future generations. Conservation and judicious use of resources are essential to prevent depletion.

Quick Revision
- Resources have value: economic, aesthetic, cultural, or sentimental
- Biotic = living origin; Abiotic = non-living origin
- Renewable resources can be replenished; non-renewable cannot
- Resources belong to individuals, communities, nations, or the international community
- Actual resources are currently used; potential resources are yet to be fully explored
- Sustainable development = balancing use today with availability for tomorrow
Practice Tips
- Practise classifying everyday items into biotic/abiotic and renewable/non-renewable categories
- Remember Gandhiji's quote on need vs. greed for essay-type questions
- Be clear on the difference between actual and potential resources with examples
