Water security refers to the capacity of. a population to safeguard sustainable access to acceptable freshwater quantity and quality for human wellbeing, livelihoods, and socio-economic development while preserving ecosystem health.
Since 2000, the western U.S. has experienced the most extended dry period and lowest soil moisture levels in 1,200 years, a combined result of low precipitation and heat, reports a new study in Nature Climate Change. The Bureau of Reclamation's 2021 SECURE Water Act report presents foundational data for the Western United States with information on hydrology, snowpack melt, climate change impacts and adaptation strategies to increase water supply reliability.
Every continent has been touched by water scarcity; some regions have exceeded freshwater sustainability limits. The 2021 IPCC report predicts growing water scarcity, ecological drought, and desertification in coming decades. Water resources management and nature-based solutions for watershed protection can strengthen freshwater ecosystem resilience.
In 2021, 2.3 billion globally, lacked home handwashing facilities. A stunning 673 million people around the world still have no access to toilets or latrines. The UN SDG 6 targets global access to ‘adequate and equitable’ water hygiene by 2030. Let's work to meet SDG6.
The Pacific Institute defines “water resilience” as the ability of water systems to function so that nature and people, including those on the frontlines and disproportionately impacted, thrive under shocks, stresses, and change. As a global thought leader on Water Resilience, the Pacific Institute 2021 brief provides a landmark framework for water resilience, security and sustainability.
Widespread drought in the western U.S. has loomed on the horizon since the 1970s. Recent decades have brought western water shortages, threatening drinking, agricultural, tribal water supplies, and recreational activities, as well as hydroelectric energy. In wildfire seasons of 2020 and 2021 economic losses register in the billions; cumulative losses will take years to assess.
If IPCC predictions for increasing desertification in the western U.S. materialize, existing patterns for agriculture, infrastructure, energy and built communities will need innovative and visionary change.
