Advancing integrated water resources management

Integrated Water Resources Management (IWRM) promotes the coordinated development and management of water, land and related resources in order to maximize economic and social welfare in an equitable manner, without compromising the sustainability of vital ecosystems.

IWRM is a cross-sectoral approach that is increasingly recognised as the solution to traditional, fragmented sectoral approaches to water resources management that have led to unsustainable use and poor services. Integrated Water Resources Management is based on the understanding that water resources are an integral component of the ecosystem, a natural resource, and a social and economic good.

The basis of IWRM is that the many different uses of finite water resources are interdependent. High irrigation demands and pollution from agriculture, for example, mean less freshwater for drinking or industrial use; contaminated municipal and industrial wastewater pollutes rivers and threatens ecosystems; if water has to be left in a river to protect fisheries and ecosystems (environmental flows), less can be diverted to grow crops.

Implementing Integrated Water Resources Management thereby helps to protect the world’s environment, foster economic growth and sustainable agricultural development, promote democratic participation in governance, and improve human health.

What we do.

United Nations Environment Programme (UNEP) has led global efforts, through UN-Water and its partners, for countries to report on the status of implementation of IWRM, agreed at the World Summit on Sustainable Development in Johannesburg in 2002, and reinforced as SDG Target 6.5 on integrated water resources management and transboundary cooperation.

UNEP is the global custodian of SDG indicator 6.5.1 on Integrated Water Resources Management, supporting countries to develop and implement national IWRM processes.

The UNEP-DHI  Centre on Water and Environment conducts extensive work on IWRM worldwide, including supporting countries to monitor, plan and implement IWRM through the Sustainable Development Goals. The IWRM Data Portal helps countries track progress towards Target 6.5.
