Global Groundwater Sustainability: A Call to Action Global Groundwater Statement A global group of scientists, practitioners, and experts calling for action to ensure groundwater benefits society now and into the future. GroundwaterStatement.ORG GroundwaterStatement.ORG GroundwaterStatement.ORG www.groundwatervisible.org Gleeson, T., Wada, Y., Bierkens, M.et al.Water balance of global aquifers revealed by groundwater footprint. Nature488,197–200 (2012). https://doi.org/10.1038/nature11295 Establishing the GroundwaterFootprint of the Islands Trust Area is a giant leap in evidence-based sustainability planning. Historically, precautionary principles aided planning through a lack of knowledge of groundwater recharge, availability, and vulnerability. However, witha changing climate and increasing societal stresses.... We cannot use the past to plan for the future. Water Champions are freshwater stewards that hold governments accountable POLIS (2019) A Handbook for Water Champions: Strengthening Decision-Making and Collaboration for Healthy Watersheds. www.poliswaterproject.org POLIS the root of word of “politics” a term that represents a rootedness in place and community. the highest of human ideals the ability to make decisions collectively for the greater good Mapping isArt. Understanding freshwater from communityvalues and traditional knowledge through storytelling and lived experience supports quantitative science. Exploring groundwater resources is at the nexus of science, technology, and art. All groundwater comes from meteoricwater. Rain, snow, and fog provide all essential freshwater for island life. Groundwater is aunique amenity in the IslandsTrust Area A subterranean geological unit that can storeand transmit water in useful quantities for domestic, industrial, and ecological use. What is an Aquifer? Groundwater regions are Water Management Units for land-use planning and water authorizations.
