Groundwater sustainability: A review of the interactions between science and policy
Concerns over groundwater depletion and ecosystem degradation have led to the incorporation of the concept of groundwater sustainability as a groundwater policy instrument in several water codes and management directives worldwide. Because sustainable groundwater management is embedded within integrated, co-evolving hydrological, ecological, and socioeconomic systems, implementing such policies remains a challenge for water managers and […]
Read MoreEconomic benefits of hydrologic services from watershed protection and restoration
Watershed protection and restoration provide a range of benefits including clean and ample water supplies, biodiversity, cultural connection to place, carbon sequestration, and a suite of other ecosystem services. Research by UHERO’s Environmental Policy and Planning Group demonstrates the economic benefits of native forest protection and restoration for groundwater recharge, pointing to the value of […]
Read MoreUHERO’s Leah Bremer on Supporting real-world watershed management
UHERO’s Leah Bremer’s recent publication in Water Resources Research was featured in the Global Water Forum this week. She and a team of interdisciplinary colleagues worked with on-the-ground managers of watershed protection programs in Brazil to identify real-world decision contexts where hydrologic modeling and monitoring can support planning and decision making. They demonstrate the importance […]
Read MoreCollaborative research to support urban agriculture in the face of change: The case of the Sumida watercress farm on O‘ahu
As urban areas expand around the world, there are growing efforts to restore and protect natural and agricultural systems for the multitude of ecosystem services they provide to urban communities. This study presents a researcher-farmer collaboration in a highly urbanized area of Oʻahu focused on understanding the historical and current challenges and opportunities faced by […]
Read MoreIncorporating Historical Spring Discharge Protection into Sustainable Groundwater Management: A Case Study from Pearl Harbor Aquifer, Hawai‘i
By Kimberly Burnett, Ahmed Elshall, Christopher Wada, Aida Arik, Aly El-Kadi, Clifford Voss, Jade Delevaux, and Leah Bremer The value of considering a range of diverse benefits is particularly salient in geographically isolated areas like the Hawaiian Islands, where judicious management of limited local freshwater resources is essential to sustaining the wellbeing of residents and […]
Read MoreIncorporating Historical Spring Discharge Protection Into Sustainable Groundwater Management: A Case Study From Pearl Harbor Aquifer, Hawai‘i
Groundwater management policy around the world increasingly seeks to protect groundwater-dependent ecosystems and associated human uses and values. This includes uses of ecosystems and agricultural systems linked to natural spring discharge. Yet, there are few examples of practical tools to balance human groundwater use with ecological water demand related to spring discharge. Using a simulation […]
Read MoreWho are we measuring and modeling for? Supporting real-world watershed management
By Leah Bremer and Kate Brauman (In Press at the Global Water Forum) Watershed management programs that promote land management like reforestation, conservation, and lower-intensity grazing to enhance clean and ample water supplies downstream are becoming more common around the world. To achieve their water goals, they often need hydrologic information, usually generated through field measurements and hydrologic models. However, hard work by the hydrologic community […]
Read MoreIdentifying priority watershed management areas for groundwater recharge protection on Hawai‘i Island
This report provides an analysis of the relative effectiveness of watershed conservation and restoration efforts in terms of groundwater recharge benefits in Hawaiʻi County Department of Water Supply (DWS) priority aquifers and recharge areas. In Kohala, Kona, and Kaʻū. With financial support from DWS and the National Science Foundation, EPSCoR ʻIke Wai project, this study […]
Read MoreContributions of native forest protection to local water supplies in East Maui
Tropical forests provide a suite of benefits including biodiversity, cultural value, and a range of ecosystem services. Globally, there is increasing interest in incentivizing native forest protection as a multi-benefit natural infrastructure strategy to secure clean and ample water supplies. In addition to conversion to agriculture and other non-forest land uses, non-native species invasion represents […]
