A consistent methodology enabling the estimation of the economic losses associated with drought and the comparison of estimates between sites and across time has been elusive. In this paper, we develop an ecosystem service approach to fill this research gap. We apply this approach to analysis of...

Growing public concern about the health of rivers and wetlands, and the ecosystems they support, puts pressure on large water users-such as the irrigation industry-to find ways to use less water. At the same time, the growing competitiveness of the economic environment places demands on the...

The possibility that genetically modified (GM) crops may contaminate non-GM crops through pollen-mediated gene flow presents a challenge to coexistence of GM agriculture with conventional and organic farming systems. In this paper an analytical model of coexistence is developed that allows for...
