The cover crop treatments consiste...

Transgenic Crops: An Environmental Assessment

Risk assessment for invasive species produces net bioeconomic benefits.

International commerce in live organisms presents a policy challenge for trade globalization; sales of live organisms create wealth, but some nonindigenous species cause harm. To reduce damage, some countries have implemented species screening to limit the introduction of damaging species. Adoption of new risk assessment (RA) technologies has been slowed, however, by concerns that RA accuracy r...
