INGENIEUR Table 2 Integrated Water Resources Management Guiding Principles IWRM Guiding Principles Freshwater is a finite and vulnerable resource. Details Water is a fixed quantity in the hydrological cycle that is required for different purposes, function and services; therefore, should involve recognition on all the characteristics of hydrological cycle, upstream and downstream, and the interaction with other natural resources. 2. Water development and management should be based on a participatory approach. All stakeholders are part of the decision making process. Participation is more than consultation to achieve the longlasting consensus and common agreement by stakeholders. 3. Women play a central part in the provision, management and safeguarding of water. Women play important role in water resources safeguarding. The gender awareness should be promoted among decision makers. 4. Water has an economic value in all its competing uses and should be recognised as an economic good In order to extract the maximum benefits from water resources, there is a need to change perceptions about water values and to recognise the opportunity costs involved in current allocated patterns. Effective water demand management can be achieved through economic instruments. 1.

Fundamentally determines the resource use, waste production and pollution of the resources and which must also set the development priorities, including: ●● Mainstreaming of water resources; ●● Cross-sectoral integration in national and local policy development; ●● Macroeconomic effects of water development; ●● Integration of stakeholders in the planning and decision making; and ●● Integration of water and wastewater management.
