Integrated Drainage Basin Management
- According to Integrated Water Resources Management (IWRM), Global Water Partnership Technical Advisory Committee 2000
“Integrated river basin management (IRBM) is the process of coordinating conservation, management and development of water, land and related resources across sectors within a given river basin, to maximise the economic and social benefits derived from water resources in an equitable manner while preserving and, where necessary, restoring freshwater ecosystems.”
- Components of integrated drainage basin management (IDBM) include:
- Water quality
- Water supply
- Flood control
- River channels
- Successful drainage basin management works with the river compared to working against the river
- There are seven key elements to successful IDBM:
- Integration
- Timing
- Participation
- Scale
- Knowledge
- Capacity
- According to the WWF, there is a need for IDBM due to:
- The freshwater crisis the world is facing
- The melting of glaciers in Pakistan and India
- This is increasing discharge in rivers
- An increase Glacial outburst floods, caused by failures of dams containing a glacial lake
- Increased land use due to urban development
- The increasing use of water for agriculture
- Approximately 12% of all animals live in freshwater and will be affected by reduced or polluted water
Costs and benefits of IDBM
Costs | Benefits |
Difficulties in involving all the stakeholders who have differing priorities and views Projects are costly Accurate data is difficult to obtain Transboundary issues can be difficult to resolve |
Helps to preserve biodiversity and maintain the ecosystem Ensures sustainable water use Minimises the risks and impacts of flooding Provides a reliable water supply |
