OBJECTIVE OF SOIL AND WATER CONSERVATION
CONSERVATION
The preservation and careful management ofthe environment and of natural resources.
Soil ConservationProtection of soil against erosion or deterioration.
Water ConservationWater conservation refers to reducing the usage of water and recycling of waste water for differentpurposes such as cleaning, manufacture, and agricultural irrigation.
SOIL AND WATER CONSERVATION
In a predominantly agricultural system, the objective of improving the productivity, profitability and prosperity of the farmers and achieving agricultural development on an ecologically sustainable basis can be attained only when conservation, development and management of the land and water resources are assured.
WHY SOIL AND WATER CONSERVATION
Land and water is a natural resource
Land provides food, fuel, fodder and shelter
Depletion of land resources and the quality of land
Soil erosion
cont…
WHY SOIL AND WATER CONSERVATION
It takes nature 600-1000 years to build 2.5 cm of top soil but get displaced in a year due to misuse, as a result it become the harmful single factor in the deterioration of productive land.
It has been proved that soil lost from unprotected land is about 120 tons ha-1 yr-1 and may go as high as 300 tons ha-1 yr-1.
OBJECTIVE OF SOIL CONSERVATION
Enhancing and sustaining productivity
Generating additional employment opportunities
Increase income through secured livelihood in rural areas.
Maintaining beneficial relationship between land and water cycles and moderate hazards of droughts and flood.
cont…
OBJECTIVE OF SOIL CONSERVATION
Retarding Watershed degradation caused by
Deforestation, Soil erosion, Land degradation Hydrologic deterioration of the watersheds.
Locating, reclaiming and developing cultivable wastelands,
OBJECTIVE OF WATER CONSERVATION
Sustainability: To ensure availability for future generations.
Energy conservation: Water pumping, delivery, and waste water
treatment facilities consume a significant amount of energy
cont…
OBJECTIVE OF WATER CONSERVATION
Habitat conservation:
Minimizing human water use helps to preserve fresh water habitats for local wildlife and migrating waterfowl, as well as reducing the need to build new dams and other water diversion infrastructure.
RECOMMENDATIONS
Water conservation programs are typically initiated at the local level, by either municipal water utilities or regional governments.
Common strategies include public outreach campaigns, tiered water rates (charging progressively higher prices as water use increases), or restrictions on outdoor water use such as lawn watering and car washing.
cont…
RECOMMENDATIONS
Cities in dry climates often require or encourage the installation of natural landscaping in new homes to reduce outdoor water usage.
Environmental Protection Agency estimates that metering alone can reduce consumption of water 20 to 40 percent.
In addition to raising consumer awareness of their water use.
cont…
RECOMMENDATIONS
Some researchers have suggested that water conservation efforts should be primarily directed at farmers, in light of the fact that crop irrigation accounts for 70% of the world's fresh water use.
Create awareness among farmers for efficient use of water
Force farmers to grow more water-efficient crops and adopt less wasteful irrigation techniques
CONCLUSION
Pakistan is one of the countries suffering from most serious soil and water loss.
1. Need to explore the law of soil and water loss, which has laid basis for erosion control.
2. Adheres to take large rivers as the diaphysis and small-watersheds as the basic unit to implement integrated management for the mountain, water, forest and roads. Such projects have produced significant results.

CONCLUSION
3. “National Guidelines for Ecological and Environmental Protection”, which outlined the master plan for soil and water conservation and ecological improvement.
4. Major ecological improvement projects as key of soil and water conservation sites,
transformation of sloping farmland into forestry, sand prevention Great achievement has taken place in soil and water conservation, as shown in four aspects.
