IWRM is an empirical concept which has been founded on the experience of water practitioners. In other words, it is not a scientific theory to be confirmed or rejected. In turn, it is a set of guidelines derived from conventional understanding of key elements of water management. Experience shows that the countries and governments who start reforms in water sector, focus on policy making, and law/regulation developing in the first place. Some challenges of IWRM implementation pertain to the integrity and the extent on the integrity. Ideally speaking, the implementation of IWRM required the integration of all aspects. In order to achieve this, coordination is the first step. IWRM implementation might take several decades to reach the point at which one can claim the water resources management is being done in accordance with principles. The pace of IWRM implementation is developing countries is slow since these countries have poor institutional capacity for change. IWRM implementation requires balancing the conflicting objectives. Having stakeholders involved is also crucial for carrying out the IWRM approach and its effectiveness. Active, non-governmental organizations or any other civic bodies are also required for the negotiations between inter-sector and stakeholders at various levels, to take place.
