Water Resources

Understanding the Links Between Local Ecological Knowledge, Ecosystem Services, and Resilience

September 16, 2014

By Kim Burnett and Cheryl Geslani UHERO’s Project Environment has received funding from the National Science Foundation to participate in an interdisciplinary, international project that spans the natural and social sciences as well as the terrestrial and marine spheres. UHERO is partnering with scientists, resource managers, cultural practitioners and private landowners in Hawaii and Fiji. […]

How Do We Manage Our Interdependent Environmental Resources?

June 27, 2014

By Christopher Wada Managing water resources requires an understanding of the linkages between key hydrologic factors and direct human influences. The problem is further complicated by the fact that water resources are often interdependent, which suggests that management should also account for ecological interlinkages. For example, a forested upstream watershed may replenish an underlying groundwater […]

Incentivizing interdependent resource management: watersheds, groundwater, and coastal ecology

June 9, 2014

Managing water resources independently may result in substantial economic losses when those resources are interdependent with each other and with other environmental resources. We first develop general principles for using resources with spillovers, including corrective taxes (subsidies) for incentivizing private resource users. We then analyze specific cases of managing water resources, in particular the interaction […]

Groundwater Economics without Equations

June 6, 2014

In many parts of the world, irrigation and groundwater consumption are largely dependent on groundwater. Minimizing the adverse effects of water scarcity requires optimal as well as sustainable groundwater management. A common recommendation is to limit groundwater extraction to maximum sustainable yield (MSY). Although the optimal welfare-maximizing path of groundwater extraction converges to MSY in […]

Optimal Joint Management of Interdependent Resources: Groundwater vs. Kiawe (Prosopis pallida)

June 4, 2014

Local and global changes continue to influence interactions between groundwater and terrestrial ecosystems. Changes in precipitation, surface water, and land cover can affect the water balance of a given watershed, and thus affect both the quantity and quality of freshwater entering the ground. Groundwater management frameworks often abstract from such interactions. However, in some cases, […]

The Good, Bad, and Ugly of Watershed Management

Efficient management of groundwater resource systems requires careful consideration of relationships — both positive and negative — with the surrounding environment. The removal of and protection against “bad” and “ugly” natural capital such as invasive plants and feral animals and the enhancement of “good” capital (e.g. protective fencing) are often viewed as distinct management problems. […]

Optimal groundwater management when recharge is declining: a method for valuing the recharge benefits of watershed conservation

February 27, 2014

Demand for water will continue to increase as per capita income rises and the population grows, and natural hazard resilience can exacerbate the problem through changes in precipitation patterns and quantities, evapotranspiration, and land cover—all of which directly or indirectly affect the amount of water that ultimately infiltrates back into groundwater aquifers. We develop a […]

Changing climate conditions threaten groundwater recharge. The potential benefits of conserving it are substantial.

February 25, 2014

By Kim Burnett and Christopher Wada Results from a recent statistical exercise suggest that by the end of the 21st century, Hawaii will likely see a 5-10% reduction in precipitation during the wet season and a 5% increase during the dry season (Timm and Diaz 2009). Given that approximately 70% of normal precipitation falls during […]
