This study examines the spatial nature of optimal bioinvasion control. We develop a spatially explicit two-dimensional model of species spread that allows for differential control across space and time, and we solve for optimal spatial-dynamic control strategies. We find that the optimal...

When every individual's effort imposes negative externalities, self-interested behavior leads to socially excessive effort. To curb these excesses when effort cannot be monitored, competing output-sharing partnerships can form. With the right-sized groups, aggregate effort falls to the socially...

To compensate for a grave environmental injustice -- climate change caused by industrial pollution -- Northern legal solutions should not exacerbate the problem. In this article, I describe how environmental goals are undermined when domestic nations of the North implement greenhouse gas...

Public trustees at the state, federal, and tribal level are tasked with ensuring that those responsible for destroying or damaging natural resources sufficiently compensate the public for its loss. Those trustees have the fiduciary duty to maintain and restore the natural resources within the...

The theory for a general equilibrium ecosystem model that can include large number of interacting species is presented. Features include: 1) individual plants and animals are assumed to behave as if they are maximizing their net energy intake, 2) short and long-run equilibriums are obtained, 3)...

Many Alaskans depend on family-centered harvests of wild fish, wildlife, and plants in what could be considered a home production model. State and federal laws provide priorities for these “subsistence uses,” a divisive political issue in Alaska. We explore Alaska’s subsistence economies...

The central question of environmental law is "how much?" How much pollution should we emit into the air and water? How much resource exploitation should we engage in? While for other "how much" questions our society tends to rely (at least in theory) on the market, when it comes to environmental...

Fisheries managers in the United States are required to identify and mitigate the adverse impacts of fishing activity on essential fish habitat (EFH). There are additional concerns that the viability of noncommercial species, animals that are habitat dependent and/or are themselves constituents...

The multispecies fisheries management looks at a bigger picture in addressing the long-term consequences of present decisions. This implies an ecosystem management that includes a number of species and their physical, biological and economic interactions. These interactions make the growth of...

The crisis of Greater Darfur region continued for the past eight years with so many postulations of the reasons behind the rebellions and uprisings there. Many voiced their concerns about human sufferings, but all agreed on that reasons focus on less or non-existent development. United Nations'...
