Integrated Water Resources Development and Management: IWRDM.
Integration of -
- River basin resources- surface and ground.
- Demands - consumptive and non-consumptive, and supplies.
- Facilities - mega to micro.
- Human and eco-systems.
- S&T and engineering with social, economic, synergic needs.
Where does the water come from?
New dams - inter-basin transfer
Groundwater - underdeveloped
Demand Management
Water savings - increase in efficiency, reduce evaporation.
Water productivity - increases in crop per drop
Trade (virtual water), import food.
WATERSHED MODELLING …
Watershed modelling steps
1. Formulation
2. Calibration/verification
3. Application
Watershed model constitutes
1. Input function
2. Output function
3. Transform function
Water Conservation
Important step for solutions to issues of water and environmental conservation is to change people's attitudes and habits
Conserve water because it is right thing to do!.
What you can do to conserve water?
Use only as much water as you require. Close the taps well after use. While brushing or other use, do not leave the tap running, open it only when you require it. See that there are no leaking taps.
Use a washing machine that does not consume too much water. Do not leave the taps running while washing dishes and clothes.
Concluding Remarks
The integrated watershed management approach
have the following major components:
Promote sustainable economic development through optimum
utilisation of natural resources and local capacity building.
Improving living conditions of the poorer through more equitable
resources distribution and greater access to income
generating activities.
