This report reviews the main linkages between climate change, water and agriculture as a means to identifying and discussing adaptation strategies for better use and conservation of water resources. It aims to provide guidance to decision makers on choosing an appropriate mix of policies and...

Water resources allocation determines who is able to use water resources, how, when and where. It directly affects the value (economic, ecological, socio-cultural) that individuals and society obtain from water resources. This report overviews how allocation works in a range of countries and how...

Endocrine disrupting chemicals (EDCs) are contaminants of emerging environmental and health concern that have been detected in freshwater, wastewater and drinking water. They interfere with the endocrine system in humans and wildlife, and produce adverse effects such as developmental,...

After decades of regulation and investment to reduce point source water pollution, OECD countries still face water quality challenges (e.g. eutrophication) from diffuse agricultural and urban sources of pollution, that is disperse pollution from surface runoff, soil filtration and atmospheric...

In both OECD and non-OECD countries the water sector is facing the challenges of increased competition for water resources, deteriorating water quality, and the effects of climate change and poor management. In this context, how can countries ensure access to adequate, sustainable and affordable...

Agriculture is the major user of water in most countries. It also faces the enormous challenge of producing almost 50% more food by 2030 and doubling production by 2050. This will likely need to be achieved with less water, mainly because of growing pressures from urbanisation, industrialisation...

The investments needed to deliver sustainable water and sanitation services, including the funds that are needed to operate and maintain the infrastructure, expand their coverage and upgrade service delivery to meet current social and environmental expectations, are huge. Yet, most systems are...

This report addresses multilevel governance challenges in water policy implementation and identifies good practices for coordinating water policy across ministries, between levels of government, and across local actors at subnational level. Based on a methodological framework, it assesses the...

Groundwater has provided great benefits to agriculture irrigation in semi-arid OECD countries, but its intensive use beyond recharge in certain regions has depleted resources and generated significant negative environmental externalities. The report provides a characterisation of the diversity...
