World Water Day 2016

Each year on March 22, World Water Day attracts international attention to the conservation and development of freshwater resources.
Water is a finite resource that is fundamental to human health and well-being. From food and energy security to human and environmental health, water is also an essential part of sustainable development. Nearly half of workers around the world (1.5 billion people) have jobs in water-related industries.1 Many industries rely on water to perform jobs, such as fishing, agriculture, manufacturing, and food service. Societies and economies depend on the people who work to keep the water we drink safe.
Managed efficiently, water plays an important role in strengthening the resilience of social, economic, and environmental systems in the face of rapid and unpredictable changes, including changes in the earth's climate. Climate change impacts water quality and availability, the infrastructure that provides access to safe drinking water, and the spread of waterborne diseases.
The World Health Organization estimates that an additional 250,000 people will die per year between 2030 and 2050 as a result of climate change.2Diarrheal diseases from contaminated water and lack of adequate sanitation and hygiene will be a major cause of these additional deaths.3
Now is the time to address these challenges and to commit to the responsible management of water resources to ensure sustainable development in the present and for generations to come.

Story from the Field: Cholera in Kenya

The world is currently experiencing an El Niño event that is bringing heavy rain and flooding to East Africa, while southern Africa is experiencing a drought. In the past, El Niño events have been linked to cholera outbreaks in the Africa Great Lakes Region countries.4 A large cholera outbreak has been ongoing in Kenya since January 2015. Patients in this outbreak did not have adequate access to safe water and sanitation services and did not practice proper handwashing.5 Infrastructure needs to be developed in response to changes in climate that affect access to safe water and adequate sanitation and hygiene.

CDC's Global Water, Sanitation, and Hygiene (WASH) Expertise

Inadequate water, sanitation, and hygiene (WASH) conditions exist in a range of settings, from temporary refugee camps to entire neighborhoods in large cities.
Since 1990, the number of persons able to access improved drinking water sources and sanitation facilities* has increased by 2.3 billion and 1.9 billion respectively. Despite these gains, hundreds of millions still lack access to these essential resources, making them susceptible to life-threatening WASH-related diseases ranging from cholera to typhoid fever to hepatitis.6 CDC's global WASH work involves partnerships with other US government agencies, ministries of health, non-governmental organizations, UN agencies, private companies and various international agencies. Our program provides expertise and interventions aimed at saving lives and reducing illness by improving global access to healthy and safe water, adequate sanitation, and improved hygiene.
The WASH program works on long-term prevention and control measures for improving health, reducing poverty, and improving socioeconomic development as well as responding to global emergencies and outbreaks of life-threatening illnesses. These improvements reduce illness and death from WASH-related disease and help to promote improved overall health, poverty reduction, and socio-economic development.

*An improved water source is defined as water that is supplied through a household connection, public standpipe, borehole well, protected dug well, protected spring, or rainwater collection. Improved sanitation facilities usually ensure separation of human waste from human contact.
