In the western United States, the management of surface water quality and quantity is highly compartmentalized. This compartmentalization among and within state and federal authorities is not inherently objectionable. To the contrary, it likely is necessary. Yet, the degree of compartmentalization appears to have so divided management of this resource that damage has been done to both sides. Opportunities exist for cooperation, coordination, and a more holistic perspective on water management with little or even no change in law.

Hundreds of briefs, decisions, and journal articles debating “how much loss is enough” should be sufficient proof that the Keystone Bituminous “taking fraction” provides poor guidance to decisionmaking in partial regulatory takings. The Penn Central court intended to measure the severity of economic impact by interference with distinct investment-backed expectations. Where lost income from use of the property is at stake, standard economics requires the denominator in the “taking fraction” to be the owner’s investment in the property.

How effective are courts as policymaking institutions? Generally speaking, courts play a far larger role in American biodiversity law than they do in comparable Australian and Canadian statutory programs. As a result, studying endangered species protection offers a useful way to identify and isolate the policy impacts of judicial intervention. In the two cases I examine, the American system functioned at least as well as, and sometimes better than, the biodiversity programs in Australia and Canada.

This Comment examines what is known about the costs associated with environmental degradation resulting from the production of commodity crops—i.e., row crops such as corn, soybeans, and wheat—that are grown on large swaths of land. Much has been written about the environmental impacts of contemporary agriculture, and the critical need for conservation practices, but far less is known about the cost of these impacts. Even less research has examined how those costs can be attributed to the various types of agricultural operations.
