The well-being of people all over the world depends on the various goods and services provided by ecosystems, including food, fuel, construction materials, clean water and air, and protection from natural hazards. Ecosystems, however, are under increasing pressure from unsustainable use of resources and other threats including outright conversion of lands, pollution, expansion of infrastructure and urbanisation.

Water and Energy Security

Both water and energy are essential to every aspect of life; social equity, human health, ecosystem integrity and economic sustainability. The longstanding division between energy and water considerations is particularly evident in the case of energy and water management. These resources are fundamentally intertwined; energy is used to secure, deliver, treat and distribute water, while water is used to develop, process and deliver energy.

Understanding Water Endowments (C1)

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.
