As more people flock to cities around the globe, increasing demands are being placed on urban water systems. Climate change and other unprecedented stressors will exacerbate the challenges related to cities' water security in the decades to come. Developed by Arup and SIWI, the City Water Resilience Approach
(CWRA) is designed to help cities grow their capacity to anticipate and mitigate water-related shocks and stressors. To commemorate World Water Day, the CWRA team has released a new set of publications
to help share information and build capacity for urban water resilience. Read More...

Water — it sustains us and the planet, and it is increasingly becoming a central focus for planning across disciplines and in the face of climate change. Many organizations are now using water as their central focus for planning and adapting to climate change, and this is the backbone of the International Water Association’s (IWA) Cities of the Future Programme (CoF). The Cities of the Future agenda harnesses the power of the IWA network to co-create solutions and join efforts to manage a city’s many waters in a sustainable and resilient manner, an approach summarized by the IWA Principles for Water Wise Cities
Coming from the ‘World’s Biggest Gathering on Water’, the 7th World Water Forum held in Korea, the IWA set out to develop what is now called the ‘IWA Principles for Water Wise Cities.’ This initiative was taken as an outcome of the theme ‘Water and Cities’ of the Forum. The driver for action was the statement that ‘vision underlies all collaborative action’ and there was a strong need identified for a document to support the development of a shared water vision between urban and water stakeholders, and in particular to inspire urban leaders on a progressive water vision.

Wetland Restoration improves livelihoods in developing citiesby Rob Cadmus (Ramsar Convention Secretariat), Chris Percival (The South Pole Group), and Ania Grobicki (Acting Secretary General, Ramsar Convention Secretariat)
Much of our increasingly urban world takes access to clean water for granted, viewing it as an inexhaustible resource. Yet today, hundreds of millions of people will go without clean water and one out of three people will not have access to proper sanitation (WHO & UNICEF, 2015). In 2010, more urban dwellers were without access to water services than in 2000 (De Castro Zoratto & Ivins, 2015), and it is estimated that by 2050 the global demand for water will increase by 55% (WWAP, 2015). Meeting basic water needs will continue to be a challenge.
As people have migrated from rural areas to urban centers in hope of jobs and education, cities have expanded outwards and in many cases have degraded the waterways and wetlands that surround them, resulting in polluted water with the worst conditions felt by the poor and disadvantaged. This cycle of expansion and degradation is seen throughout the world, but is particularly striking in some of the least developed countries where informal settlements and slums have sprawled faster than basic services. Nearly 900 million people will live in slums by 2020 (WHO & UN-Habitat, 2010), and in developing countries 90% of sewage is discharged untreated into water bodies (Corcoran et al., 2010). In many of these informal settlements, pollution and open sewers contaminate water, resulting in disease and deaths. The UN estimates that approximately 3.5 million people die each year as a result of inadequate water, sanitation, and hygiene (UN Water, 2013). Further, these populations are often the most vulnerable to natural disasters, food shortages, and the impacts of climate change. Read More...
