Sierra Valley, located in the northern Sierra Nevada, California, serves as the Middle Fork Feather River headwaters and provides surface water to Oroville Dam of the California State Water Project (SWP). Under California’s Sustainable Groundwater Management Act (SGMA),...

This paper discusses groundwater sustainability in California’s Sierra Valley based upon review of various hydrologic and geologic data sets and publications and presents our findings in the context of the 2014 Sustainable Groundwater Management Act (SGMA). The discussi...

On-farm recharge (OFR) is a practice that uses surface water to alleviate demand on and replenish groundwater supplies. It can take on two forms: in lieu recharge and direct recharge. In lieu recharge utilizes surface water supplies instead of groundwater to irrigate cr...

This assessment set out to investigate why fish farming has spread in Tonkolili District yet been poorly adopted in neighboring Bombali District. The purpose was to analyze what was working in Tonkolili but not in Bombali and then extrapolate this beyond Tonkolili. The ...

Inland valley swamps (IVSs) form part of the upland-inland valley continuum in Sierra Leone, occupying the lowest position in the landscape. This study aimed to analyze the actual use, constraints on the use and the agro-potential of IVS in Tonkolili District. Through i...

This project has focused on better understanding the potential impact of On-Farm Flood Capture and Recharge (OFFCR) on groundwater quality pertaining to salts and nitrate and on assessing potential management opportunities. To achieve these goals, we used a combination ...

Groundwater in much of California’s Central Valley (CV) has been critically over-drafted resulting in the implementation of the 2014 Sustainable Groundwater Management Act (SGMA). As Groundwater Sustainability Agencies (GSAs) work to comply with SGMA requirements and ti...

The goal of WorldFish’s research on markets and value chains is to increase the benefits to resource-poor people from fisheries and aquaculture value chains by researching (1) key barriers to resource-poor men, women and other marginalized groups gaining greater benefit...

The fisheries sector in Cambodia contributes 8%–12% to national GDP and 25% - 30% to agricultural GDP, with an estimated 4.5 million people involved in fishing and associated trades. Fish and other aquatic animals are important food sources, contributing an estimated na...
