The production of many crops depends on biotic pollination. As pollinator populations decline, assessments of the potential consequential loss of economic value are critical. We estimate the economic value of pollination services ($608 million), crop vulnerability ratio (21 percent), and...

Groundwater use plays an important role in agriculture where the lack of timely rainfall can lower yields. Policy makers strive to conserve ecosystem services, such as groundwater supply, while at the same time providing for economic growth. We develop a spatially explicit landscape level model...

This paper reviews water quality investments that can increase the environment’s capacity to remove nutrients. The nutrient removal effectiveness, uncertainty, and cost of removing nutrients directly from ambient waters is compared to agricultural nonpoint source reductions in the context of...
