Questions and Answers

What do you understand by resource? Give examples.

A resource is anything that can be used to satisfy human needs and wants. Examples include natural resources such as land, water, air, and minerals, as well as human resources such as labor and skills.

Write the classification of resources on four different basis.

Resources can be classified on the basis of their origin, availability, renewability, and ownership.

Distinguish between: a) Potential and developed resources b) Stock and reserves

Potential resources are resources that are not yet discovered or known to exist. Developed resources are resources that have been explored, extracted, and are ready for use.

Stock refers to the total amount of a resource that is available for use. Reserves are the portion of stock that is still in the ground and not yet extracted.

Potential resources are resources that are known to exist but have not yet been developed for use. Developed resources are resources that have been extracted, processed, and made available for use. (correct)

Stock refers to the total amount of a resource that is available at a given time. Reserves are the portion of stock that is economically feasible to extract and use at current prices and technology. (correct)

List the problems which resulted due to indiscriminate use of resources by man.

Indiscriminate use of resources has led to various problems such as depletion of resources, environmental degradation, pollution, and climate change. Signup and view all the answers

What do you understand by "Sustainable resource development"?

Explain three stages of resource planning.

The three stages of resource planning are: 1) Exploration and assessment: Identifying and evaluating available resources. 2) Extraction and processing: Extracting and transforming resources into usable forms. 3) Distribution and consumption: Making resources available to consumers and using them efficiently.

Write the major features of Rio de Janeiro earth summit 1992.

The Rio Earth Summit 1992, also known as the UN Conference on Environment and Development, focused on promoting sustainable development and addressing global environmental challenges. Key features include the adoption of Agenda 21, a comprehensive action plan for sustainable development, and the establishment of the UN Framework Convention on Climate Change.

What do understand by current fallow, Net sown area, Gross cropped area?

Current fallow refers to land that is kept idle in a specific year for soil recovery and nutrient replenishment. Net sown area represents the total area of land that is actually sown with crops. Gross cropped area refers to the total area of land that is sown with crops, including areas where multiple crops are grown in a single year. Signup and view all the answers

Write characteristics of Regur soil and Alluvial soil.

Regur soil is a black cotton soil, rich in clay, calcium carbonate, and iron. It is known for its fertility and water retention capacity. Alluvial soil is formed by the deposition of sediments by rivers, making it fertile and suitable for agriculture. Alluvial soil is rich in nutrients and has good water holding capacity.

Write 4 methods of soil conservation.

Four methods of soil conservation include: 1) Contour farming: Planting crops along the contour lines of a slope to reduce soil erosion. 2) Crop rotation: Alternating different crops in a field to improve soil health and reduce pest infestation. 3) Terrace farming: Creating flat steps or terraces along slopes to prevent soil erosion and enhance water retention. 4) Windbreaks: Planting trees or shrubs around fields to reduce wind erosion and provide shelter for crops.

Study Notes

Resource Classification and Understanding

Resources are understood as anything useful to humans, with examples including air, water, minerals, and fertile land.
Resources can be classified based on four criteria:
- Exhaustibility (renewable/non-renewable)
- Origin (biotic/abiotic)
- Location (local/national/global)
- Use (material/energy/other)
Potential resources are resources that are available but haven't yet been developed or utilized.
Stock represents the total amount of a resource available, while reserves represent the estimated amount of a resource that can be extracted economically.

Resource Problems

Indiscriminate resource use leads to various problems.
- Examples of problems include depletion of resources, pollution, habitat destruction and soil erosion.

Sustainable Resource Development

It involves managing resources to meet current needs without compromising the ability of future generations to meet their own needs.

Resource Planning Stages

Resource planning involves a sequence of stages to manage and utilize resources efficiently.
Three possible stages are:
- Exploration and assessment of resources
- Development and allocation of resources
- Regulation and monitoring of resources

Rio de Janeiro Earth Summit 1992

The Earth Summit, in Rio de Janeiro, 1992, underscored the importance of sustainable development.

Soil Types: Regur and Alluvial

Regur soil and Alluvial soils differ in their characteristics.

Soil Conservation Methods

Four methods to conserve soil include crop rotation, terracing, contour farming and cover cropping.
