2. LAND AS A RESOURCE
• Land is the major constituent of the lithosphere and is an
important resource for mankind and other organisms.
• The living organisms, plants and vegetation are supported by
land.
• It is rich in resources like minerals, organic as well as inorganic
matter and to some extent air and water.
• It plays pivot role in some complex processes such as
production of food as well as decomposition of dead organic
matter by microbes.

3. VARIOUS USES OF LAND
• Food production(Agriculture).
• Houses the living species of the nature.
• Industrial and Commercial purpose.
• Residential Purpose.
• Waste Disposal.
• Energy purpose.

4. EXAMPLES

5. LAND USAGE PATTERN
• Agricultural Land 11%
• Pastures and Meadows 22%
• Forest Land 30%
• Urban Land 37%

6. YOUR NATURAL RESOURCE IS IN
DANGER!!!

7. Land Degradation
Land degradation is the temporary or permanent
lowering of the productive capacity of land (UNEP,
1992).
 Causes of Land Degradation:
Natural Causes:
•Heavy rains
•Natural disasters
•High – speed winds

9. Anthropogenic Causes:
Mining:
Urbanization:
Deforestation:
Overgrazing:
Dams and Canals:
Fertilizers:

11. WHAT TO DO?

12. SUSTAINABLE LAND MANAGEMENT
• SLM can be defined as “the use of land resources, including soils, water,
animals and plants, for the production of goods to meet changing
human needs, while simultaneously ensuring the long-term productive
potential of these resources and the maintenance of their environmental
functions” (UN Earth Summit, 1992).
• TerrAfrica (2005) has further defined sustainable land management as
“the adoption of land use systems that, through appropriate
management practices, enables land users to maximize the economic
and social benefits from the land while maintaining or enhancing the
ecological support functions of the land resources”.

13. WHAT YOU CAN DO??

16. IS LAND A RENEWABLE
RESOURCE?

17. We can consider land as renewable resource if utilized carefully.
The roots of the trees and grass bind the soil. But if the forests are
depleted and grass lands are overgrazed, soil erosion, i.e. , loss of top
productive soil occurs and the land becomes unproductive.
Intense irrigation leads to water logging and salinized soil on which
crop cannot grow.
Land is also converted into a non-renewable resource when highly toxic
material and nuclear waste is dumped in it.
Thus, if managed efficiently, this natural resource indeed can be
considered as a renewable resource
YES….!!!!
