Five cities selected to develop global water resilience framework

cities

Cities from five continents have been selected to contribute to the development of a global framework for water resilience. The City Water Resilience Framework (CWRF), developed by Arup with support from The Rockefeller Foundation, will help cities better prepare for and respond to shocks and stresses to their water systems.

Amman, Cape Town, Mexico City, Greater Miami and the Beaches, and Hull were selected because they represent the range of water challenges facing cities around the world. They have also been selected because of their diversity in terms of size of population, geographic location and economic status and because of their commitment to taking a strategic approach to resilience. Four of the five cities are part 100 Resilient Cities – Pioneered by The Rockefeller Foundation, which helps cities around the world become more resilient in the face of physical, social and economic challenges.

As part of this partnership, the project will explore each cities specific water concerns through field research and stakeholder interviews conducted with Arup. Data and findings will be used to establish qualitative and quantitative indicators to measure city water resilience, for use in any city anywhere. The resulting City Water Resilience Framework will be a global standard for water resilience, which enables cities to diagnose challenges related to water and utilize that information to inform planning and investment decisions.

  • Amman, the capital city of Jordan with a population of 4 million, is not located near sources of water and regularly experiences drought. The city also experiences unusually heavy rains, leading to flooding in the lower-lying areas of the city.
  • Cape Town, in South Africa with a population of 3.7 million has been experiencing severe drought, due to three years of low rain fall. Officials have warned that there are fewer than 90 days left before the city’s water supply runs dry.
  • Mexico City, the largest of the cities participating, has a population of 21.3 million. The rapidly growing city is heavily reliant on underground aquifers, and is at serious risk of running out of water in the future. Mexico City is also located on land that was once a lake, making it particularly prone to flooding.
  • Greater Miami, and the Beaches, with a population of 5.9 million, is a coastal location with a high groundwater table and complex canal system, making it particularly vulnerable to rising sea levels. Tidal flooding events are already becoming increasingly common, causing significant disruption.
  • Hull located in Yorkshire United Kingdom, has a population of 323,000. With 90 per cent of the city standing below the high-tide line it is particularly vulnerable to rising sea levels. The city has experienced extensive flooding in recent years.

The development framework is being overseen by a Steering Group with representatives from The Rockefeller Foundation, 100 Resilient Cities, the World Bank, University of Massachusetts-Amherst, the Alliance for Global Water Adaptation (AGWA) and The Resilience Shift.

Andrew Salkin, senior vice president of city solutions at 100 Resilient Cities, said: Of the more than 1,000 applications for the 100 Resilient Cities Network, more than 60% indicated challenges with water – too much or too little – as critical resilience risks. There is tremendous opportunity for the cities in this cohort to provide lessons and expertise to the many cities around the world grappling with water challenges.”

Mark Fletcher, global water leader at Arup, said: “A changing climate coupled with rapid urbanisation is increasing the frequency of water related crises facing cities. Increasingly, unpredictable rainfall, flooding and droughts are impacting cities across their water cycle. To develop a global framework we’ve selected five diverse cities, all facing very different water challenges. By understanding a wide range of issues, being played out in different contexts, we will be able to help all cities to understand how to assess the risks they are facing, and how to prioritise action and investments to become more resilient.”
