 World Water Day 2020: Water And Climate Change 

Date of Publish - Sunday, 22nd March 2020

Today is World Water Day. This year the theme is water and climate change, focusing on the inextricable linkages between water security and the climate system. The World Water Day 2020 campaign shows how our use of water will help reduce floods, droughts, scarcity and pollution, and will help fight climate change itself. By adapting to the water effects of climate change, we will protect health and save lives. And, by using water more efficiently, we will reduce greenhouse gases.

The annual United Nations (UN) observance focusing on the importance of freshwater is held every year on the 22nd of March since it was first organized in the year 1993. UN-Water, which is the UN’s coordination mechanism on water and sanitation decides on the theme for World Water Day every year.

World Water Day celebrates water and raises awareness of the 2.2 billion people living without access to safe water. It is about taking action to tackle the global water crisis. A core focus of World Water Day is to support the achievement of Sustainable Development Goal 6: water and sanitation for all by 2030.

The global climate crisis is inextricably linked to water. Climate change increases variability in the water cycle, inducing extreme weather events, reducing the predictability of water availability, affecting water quality and threatening sustainable development and biodiversity worldwide.

Growing demand for water increases the need for energy-intensive water pumping, transportation, and treatment, and has contributed to the degradation of critical water-dependent carbon sinks such as peatlands. And, some climate change mitigation measures, such as the expanded use of biofuels, can further exacerbate water scarcity.

The UN-Water report last month highlighted the linkages between freshwater and biodiversity. Freshwater ecosystems host exceptional biodiversity; covering less than 1% of the Earth’s surface, they harbor more than 10% of all species. Despite their critical importance, the biodiversity crisis impacts freshwater ecosystems most significantly out of all ecosystems.

More than 50% of all wetlands globally have been lost since 1900 with inland wetlands being lost faster than coastal and marine, and freshwater vertebrate populations have fallen by 83% since 1970, which is more than twice as steeply as terrestrial or marine populations.

Last year, an UN-Water Policy Brief on Climate Change and Water elaborated on the need for national and regional climate policy and planning for an integrated approach to climate change and water management. The Policy and Analytical Briefs documents also stated that increased water stress and meeting future demands will require increasingly tough decisions about how to allocate water resources between competing water uses, including for climate change mitigation and adaptation.

Humans need water to survive, as do all the systems we rely on: sanitation, healthcare, education, business and industry. As the global population grows, so does the demand for water, which depletes natural resources and damages the environment in many places. Solutions include protecting carbon sinks such as oceans and wetlands, adopting climate-smart agricultural techniques, and increasing the safe reuse of wastewater. Water is our most precious resource and we must use it more responsibly.
