The first step of working towards water security is to understand the nature and the scope of the resource itself. That means taking a holistic view of the water resources in a given country or region and relating those to their use by society and the environment. For that, demand and supply need to be assessed and data on the physical and the socio-economic aspects of the resource gathered. It is also important to understand how policies are performing, which is why indicators for IWRM should be developed and used for monitoring and evaluation.
