NCERT Summary: Resources | Geography (Prelims) by Valor Academy - UPSC PDF Download

Resources

• Resources are defined as anything that can be used to satisfy a need.
• Utility or usability determines whether an object or substance is considered a resource.
  • Example resources include water, textbooks, etc.
• While some resources like metals have economic value, others like a beautiful landscape may not, but both satisfy human needs.
• Some resources can gain economic value over time, for instance, traditional home remedies.

Factors Influencing Resources

• Time and technology play crucial roles in transforming substances into valuable resources.
• People themselves are the most significant resource, contributing ideas, knowledge, inventions, and discoveries that lead to the creation of more resources.
• Every invention leads to the development of many others, such as how the discovery of fire led to various cooking practices and other innovations.

Types of Resources

• Natural Resources
• Human Made Resources
• Human Resources

Natural Resources

• Natural resources are those drawn from nature and used with minimal modification.
• Many natural resources are gifts from nature and can be utilized directly. Sometimes, tools and technology are necessary to make the best use of a natural resource.

• Natural resources are categorized based on their level of development and use:
  • Origin: Indicates where the resource comes from.
  • Stock: Refers to the quantity of the resource available.
  • Distribution: How the resource is spread out.
• Resources can be classified into two groups based on their development and use:
  • Actual resources: Resources with a known quantity that are currently being utilized. For example, the dark soils of the Deccan plateau in Maharashtra.
  • Potential resources: Resources with unknown quantities that are not currently being used due to technological limitations. For instance, the uranium found in Ladakh, which could be utilized in the future with advanced technology.
• Resources can also be classified based on their origin:
  • Abiotic resources: Non-living resources like soil, water, and rocks.
  • Biotic resources: Living resources such as plants and animals
• On the Basis of Stock:
  • Renewable Resources: Resources like solar or wind energy that are unlimited and unaffected by human activities. Careless use of resources such as water, soil, and forests can deplete their stock.
  • Non-renewable Resources: Resources like coal and petroleum that have a limited stock. Once depleted, they may take thousands of years to renew, making them non-renewable.
• On the Basis of Resource Distribution
  • Ubiquitous Resources: Resources like air and water found everywhere.
  • Localized Resources: Resources like copper and iron ore found only in certain places.

Human Made Resources

• Natural substances become resources only after their original form is altered. For example, iron ore becomes a resource after extracting iron from it.
• Technology is considered a human-made resource that enhances resource utilization.

Human Resources

• People utilize nature effectively through knowledge, skills, and technology, making them valuable resources.
• Education and health contribute to enhancing human resource value.
• Developing people's skills to create more resources is known as human resource development.

Resource Conservation

• Using resources carefully and giving them time to get renewed is called resource conservation.

• Sustainable development is the development meets the needs of present and also conserve them for the future.
• Principles of Sustainable development:
  → Respect and care for all forms of life
  → Improve the quality of human life
  → Conserve the earth’s vitality and diversity
  → Minimise the depletion of natural resources
  → Change personal attitude and practices toward the environment
  → Enable communities to care for their own environment.
• It is our duty to ensure that:
  → All uses of renewable resources are sustainable
  → The diversity of life on the earth is conserved
  → The damage to natural environmental system is minimised.
