The Nature Conservancy & C40 Release Urban Water Blueprint

Today, The Nature Conservancy released a report analyzing the state of water resources for 530 cities worldwide. The report – Urban Water Blueprint: Mapping Conservation Solutions to the Global Water Challenge – and interactive websitewere done in partnership with C40 and the International Water Association, and offer recommendations for how to revitalize strained water resources and improve water quality.

As a complement to the report, the partners published a feature highlighting new analysis of C40 data on water management in the world’s leading megacities. By demonstrating the relationship between risk assessment, mayoral power and action, and providing examples from C40 cities, the research points toward a robust toolkit available to all cities to deliver high quality and sustainable water supplies.

“This report addresses a critical issue facing mayors in cities around the world: access to clean and adequate water supplies,” said C40 Chair and Rio de Janeiro Mayor Eduardo Paes. “The growth of urban populations, coupled with incidences of sudden climate stress and long-term land degradation of drinking watersheds, pose increasing risks to urban water supply with serious implications for the future health and well-being of urban residents. Without water, cities cannot thrive.”

The report notes that one in four of the world’s largest cities – which account for more than 800 million people – are currently water stressed, while others face challenges in water quality. The report also identifies significant savings – to the tune of $890 million – if water utilities invested in watershed conservation activities.

The C40 Cities Climate Leadership Group (C40) is a network of large and engaged cities from around the world committed to implementing meaningful and sustainable climate-related actions locally that will help address climate change globally. Recognizing that cities consume over two-thirds of the world’s energy and account for more than 70% of global CO2 emissions, our organization’s global field staff works with city governments, supported by our technical experts across a range of program areas to reduce carbon emissions and increase energy efficiency in large cities across the world. The current chair of the C40 is Rio de Janeiro Mayor Eduardo Paes, and 108th Mayor of New York City Michael R. Bloomberg is President of the Board. The Steering Committee includes: Berlin, Buenos Aires, Copenhagen, Hong Kong, Houston, Jakarta, Johannesburg, London, Los Angeles, Rio de Janeiro, Seoul and Tokyo.

    Wetland in the world are trampled for the benefit of few. Mines and municipalities drain sewage into rivers. Countries do not protect and enforce laws that protect water resource. people lack job, and those who sit in jobs don’t do the water conservation.
