The United Nations World Water Development Report (WWDR), released every year with a focus on different strategic water issues each year, is the UN’s flagship report on water. It is a comprehensive review that gives an overall picture of the state of the world's freshwater resources and aims to provide decision-makers with the tools to implement sustainable use of our water.

Through a series of assessments, the Reports provide a mechanism for monitoring changes in the resource and its management and tracking progress towards achieving targets, particularly those of the Millennium Development Goals (MDGs, 2000-2015), and now those of the Sustainable Development Goals (SDGs, 2016-2030). The Reports also offer best practices as well as in-depth theoretical analyses to help stimulate ideas and actions for better stewardship in the water sector.

The development of the WWDR, coordinated by WWAP, is a joint effort of the UN agencies and entities, which make up UN-Water, working in partnership with governments, international organizations, non-governmental organizations and other stakeholders.

The 2018 edition of the World Water Development Report (WWDR 2018) seeks to inform policy and decision-makers, inside and outside the water community, about the potential of nature-based solutions (NBS) to address contemporary water management challenges across all sectors, and particularly regarding water for agriculture, sustainable cities, disaster risk reduction and water quality.

NBS use or mimic natural processes to enhance water availability (e.g., soil moisture retention, groundwater recharge), improve water quality (e.g., natural and constructed wetlands, riparian buffer strips), and reduce risks associated with water-related disasters and climate change (e.g., floodplain restoration, green roofs).

The WWDR2018, titled Nature-based solutions for water, demonstrates how nature-based solutions (NBS) offer a vital means of moving beyond business-as-usual to address many of the world’s water challenges while simultaneously delivering additional benefits vital to all aspects of sustainable development.

Currently, water management remains heavily dominated by traditional, human-built (i.e. ‘grey’) infrastructure and the enormous potential for NBS remains under-utilized. NBS include green infrastructure that can substitute, augment or work in parallel with grey infrastructure in a cost-effective manner. The goal is to find the most appropriate blend of green and grey investments to maximize benefits and system efficiency while minimizing costs and trade-offs.

NBS for water are central to achieving the 2030 Agenda for Sustainable Development because they also generate social, economic and environmental co-benefits, including human health and livelihoods, food and energy security, sustainable economic growth, decent jobs, ecosystem rehabilitation and maintenance, and biodiversity. Although NBS are not a panacea, they will play an essential role towards the circular economy and in building a more equitable future for all.

Working with nature improves the management of water resources, helps achieve water security for all, and supports the core aspects of sustainable development.

The World Water Development Report will be presented at the 8th World Water Forum, in Brasilia (Brazil) on the 19th of March.
