“…While the science around forest type and water use remains limited (Wright et al 2018), this study utilizes the best available data to demonstrate the critical role that watershed partnerships and other source watershed protection efforts play in maintaining groundwater recharge, particularly in a context of current drying trends (Frazier and Giambelluca 2017). This study corroborates previous research on the economic value of watershed protection (Bremer et al 2019;Wada et al 2020), and also provides a more realistic evaluation of impacts on groundwater management and replacement costs through the linkage to a groundwater model and simulation optimization approach.…”

“…However, there are few examples of hydrologic ecosystem services studies that link watershed ecohydrologic processes to economic and other well-being metrics (Brauman 2015), particularly in a context of climate change. The majority of existing valuation studies focus on the impacts of watershed protection on water quality rather than quantity (Keeler and Polasky 2014;Ozment et al 2018;Kroeger et al 2019), and those that do focus on groundwater ecosystem services directly link recharge to economic value (without consideration of groundwater dynamics) or utilize highly simplified groundwater modeling frameworks (Brauman 2015;Bremer et al 2019;Burnett and Wada 2014;Wada et al 2020). This leaves important gaps in the understanding of how spatially heterogeneous watershed management and aquifer dynamics influence the value of watershed management.…”

“…While significant uncertainty remains on the impacts of species invasions on tropical ecohydrology (Hamel et al 2017;Wright et al 2018), a growing body of field studies suggest greater transpiration rates-and thereby lower groundwater recharge rates-in typical nonnative, invasive versus typical native forest stands (Giambelluca et al 2008;Kagawa et al 2009;Cavaleri et al 2014). Several studies in Hawai'i have utilized water balance and other hydrologic models parameterized by limited field data to assess the impact of land cover, including watershed protection on groundwater recharge (Engott 2011;Burnett et al 2017;Povak et al 2017;Brewington et al 2019), and linked economic metrics (Burnett and Wada 2014;Brauman et al 2015;Bremer et al 2019;Wada et al 2020). However, none of these studies link groundwater recharge to management implications through a spatially explicit groundwater model to evaluate the combined effect of watershed protection and climate change.…”

Groundwater sustainability initiatives, including sustainable yield and watershed policy protection policies, are growing globally in response to increasing demand for groundwater, coupled with concerns about the effects of climate and land-cover change on groundwater supply. Improved understanding of the impacts of watershed management on groundwater yields and management costs—particularly in the broader context of climate and land-cover change—is critical to inform these initiatives and facilitate integrated land and water management. This study develops a novel, spatially explicit groundwater hydrologic ecosystem services framework, which combines stakeholder-defined land-cover scenarios, sustainable yield estimation using a groundwater simulation optimization approach, and economic valuation, and applies it in the most heavily utilized aquifer Hawai‘i (USA). Sustainable yield estimates and resulting differences in replacement costs are estimated for six land-cover scenarios (with varying levels of urban development and watershed management) crossed with two water demand scenarios in a context of a dry future climate (Representative Concentration Pathway [RCP] 8.5 mid-century). Land-cover change is found to be an important, though less significant drive of changes in groundwater recharge than climate change. The degree of watershed protection, through preventing the spread of high-water-use, invasive plant species, is projected to be a much stronger land-cover signal than urban development. Specifically, full forest protection increases sustainable yield by 7–11% (30–45 million liters per day) and substantially decreases treatment costs compared with no forest protection. Collectively, this study demonstrates the hydrologic and economic value of watershed protection in a context of a dry future climate, providing insights for integrated land and water policy and management in Hawai‘i and other regions, particularly where species invasions threaten source watersheds.

“…Rong et al, 2019). Effective watershed management can play an important role in managing the damage runoff (Fu et al, 2019), reducing the impact of sediment output and river erosion (Du et al, 2016), increasing groundwater storage (Ghorbani Nejad et al, 2017), and utilizing land and water resources (Ervinia et al, 2019;Wada et al, 2020). A watershed is a region that sustains all kinds of runoff of the stream, lake, or ocean.…”

Coastal groundwater-dependent ecosystems (GDEs), such as wetlands, estuaries and mangrove forests, are globally important habitats that promote biodiversity, provide climate regulation and serve as refugia for plant and animal communities. However, global warming, coastal development and over-abstraction threaten the availability and quality of groundwater in coastal aquifers and, by extension, the ecohydrological function of dependent ecosystems. Because ecohydrological knowledge of coastal groundwater is disparate across disciplines and habitat types, we begin by summarising the physiochemical, biological and hydrological processes supported by groundwater across coastal watersheds. Groundwater makes a significant but poorly recognised contribution to the function and resilience of coastal ecosystems and will play an essential role in climate change mitigation and adaptation. This review then explores how critical ecosystem processes supported by groundwater will be affected in areas of the humid subtropics that are expected to be impacted by climatic drying. Where rainfall is predicted to decrease, reduced groundwater recharge will interrupt the hydrology of coastal GDEs, while anthropogenic pressures, such as land-use intensification and pollution, will diminish the quality of remaining groundwater. The challenges of managing groundwater for multiple purposes under climate change predictions are highlighted. To improve the management of coastal GDEs, research should be aimed at developing robust conceptual models of coastal groundwater systems that quantify biophysical linkages with ecological communities across relevant spatiotemporal scales.
