Ecological Studies, Environmental Impact : Expert Reports

The division produces 60-70 reports per year. These reports are unique, authoritative expert evaluations. Each report is produced by a committee of experts selected by the Academy to address a particular statement of task and is subject to a rigorous, independent peer review. The experts who volunteer their time participating on study committees are vetted to make sure that the committee has the range of expertise needed to address the task, that they have a balance of perspectives, and to identify and eliminate members with conflicts of interest. All reports undergo a rigorous, independent peer review to assure that the statement of task has been addressed, that conclusions are adequately supported, and that all important issues raised by the reviewers are addressed. Thus, while the reports represent views of the committee, they also are endorsed by the Academy.

Evaluating the Effectiveness of Fish Stock Rebuilding Plans in the United States (2013)

Fish stock rebuilding plans have proven successful in reducing fishing pressure on many overfished stocks, and stock sizes have generally increased. However, in some cases fisheries have not rebuilt as quickly as the plans projected, due to factors such as overestimation of the size of stocks and incidental catch by fisheries targeting other species. Even when fishing is reduced appropriately for the actual stock size, the rate at whic... More >>

An Ecosystem Services Approach to Assessing the Impacts of the Deepwater Horizon Oil Spill in the Gulf of Mexico (2013)

As the Gulf of Mexico recovers from the Deepwater Horizon oil spill, natural resource managers face the challenge of fully understanding the impacts of the spill and setting priorities for restoration work. The full value of losses resulting from the spill cannot be captured, however, without consideration of changes in ecosystem services--the benefits delivered to society through natural processes. The use of an ecosystem services approach t... More >>

Assessing Risks to Endangered and Threatened Species from Pesticides (2013)

When determining the potential effects pesticides could pose to endangered or threatened species, the U.S. Environmental Protection Agency (EPA), National Marine Fisheries Service (NMFS), and Fish and Wildlife Service (FWS) should use a common scientific approach, this report finds. Specifically, the agencies should use a risk-assessment approach that contains problem formulation, exposure analysis, effects analysis, and ris... More >>

Himalayan Glaciers: Climate Change, Water Resources, and Water Security (2012)

Scientific evidence shows that most glaciers in South Asia's Hindu Kush Himalayan region are retreating, but the consequences for the region's water supply are unclear, this report finds. The Hindu Kush Himalayan region is the location of several of Asia’s great river systems, which provide water for drinking, irrigation, and other uses for about 1.5 billion people. Recent studies show that at lower elevations, glacial retreat is unlikely t... More >>
