TRANSCRIPT
RESOURCE DEGRADATIONANDRURAL LIVELIHOODS
THE MEANING Resource:
A stock or supply of money, materials, staff, and other assets that can be drawn on by a person or organization in order to function.
Resource degradation is the deterioration of the resources such as air, water and soil; the destruction of ecosystems and the extinction of wildlife.
Acc. to UN it is “the reduction of the capacity of the environment to meet social and ecological objectives, and needs”
DEGRADATION: TYPES
o Water deteriotion
o Land degradation
o Air pollution
o Mining degradation
DEGRADATION: TYPESWATER DETERIOTION
Estimated that 1 in 3 people over theentire globe are already facing watershortages.
1/5th of the world’s population live inareas of physical water scarcity.
The worst sufferers are the rural people as they do not have the luxuryof municipal water supply.
DEGRADATION: TYPESWATER DETERIOTION
Causes Chemicals and other contaminants Thermal pollution
Thermal pollution is the rise or fall in the temperature of a natural body of water caused by human influence.
Thermal pollution, unlike chemical pollution, results in a change in the physical properties of water.
Common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers
Domestic sewage Industrial wastewater
WATER DETERIOTIONANDRURAL LIVELIHOODS
Water-borne diseases Lack of medical facilities make them the worst
sufferers.
Ground water contamination Their source of drinking water is also affected
Aquatic animals die due to pollution Source of livelihood affected
DEGRADATION: TYPESLAND DEGRADATION
The reduction in the capacity of the land to provide ecosystem goods and services and assure its functions over a period of time
DEGRADATION: TYPESLAND DEGRADATION
Components of land degradation: Loss of biodiversity
Decrease in the number of plantand animal species
Salinization Rapid increase in
the salt content insoil.
Loss in fertility of soil.
DEGRADATION: TYPESLAND DEGRADATION
Out-migration Many villages have been
abandoned because of low fertility of lands.
LAND DEGRADATIONANDRURAL LIVELIHOODS
Loss of fertility results in lower agriculture production Forced to buy grains Increase in poverty
The one and only source of income, i.e agriculture is badly affected
Number of diseases also surface. Livestock are affected as they do cannot be
fed properly. Livestock are exposed to diseases.
DEGRADATION: TYPESAIR POLLUTION
Air pollution is the introduction of chemicals, particulate matter or biological materials into the atmosphere that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment.
Causes: Emission from factories
Burning of firewood
DEGRADATION: TYPESAIR POLLUTION
Health Effects: Cardio-vascular
diseases
Skin problems
Lung cancer
Bronchial asthma
Breathing problems
DEGRADATION : TYPESMINING DEGRADATION
Mining is the extraction of valuable minerals or other geological resources from the earth.
The nature of mining processes create a potential negative impact on the environment both during the mining operations and for years after the mine is closed
CAUSES:
Scientific methods of mining are not used
Land reclamation is not done after mining is over
Replantation is also not done
Precautionary measures are not taken
ENVIRONMENTAL IMPACT OF MINING
Soil Erosion
Formation of sinkholes
Loss of biodiversity
Contamination of soil, groundwater and surface water
CONCLUSION
We must understand that rural livelihoods is deeply connected to the resource availability.
Rural areas have been facing the brunt of industrialization and modernization.
Government has taken little efforts to correct the problem
Forest rights act of 2006 is one of the efforts taken by govt to redress the issue.
Recently environment ministry has also become pro-active in closing down polluting industries.
In the end we must realize that we must be responsible while using the resources .
Today rural areas are suffering, tomorrow everyone of will suffer as our lives are interdependent
Thank You!
