ENVIRONMENTAL RESEARCH CENTER


By Katrina Brown

The Centre for Economic and Social Research on the Global Environment (CSERGE), based at the University of East Anglia and University College London in the UK has recently celebrated its first year anniversary. Funded by the UK Government's Economic and Social Research Council, the Centre undertakes policy- oriented research on global environmental issues focused on three main topics: loss of global biodiversity, climate change and institutional adaptation.

A recent project undertaken by CSERGE researchers and collaborators has sought to examine the range of values of medicinal plants. The study has involved the valuation of medicinal plants on a number of different levels. One aspect examines the global value of pharmaceuticals derived from medicinal plants, and attempts to quantify the monetary value of these and of the potential values which could be derived from as yet undiscovered substances isolated from plant material. Such values are often used to justify conservation projects, for example in tropical forests.

Within a developing country context, on the other hand, the use of medicinal plants within traditional medicinal systems is not only economically important, but also inextricably linked to cultural values concerning the relationship between humans and the natural environment, and beliefs on the natural and super- natural causes of disease. This in turn affects how people manage and conserve the environment. For example, in Ghana, areas of natural forest are preserved as sacred groves, where medicinal plants may be gathered by priests for use by the local community. Access and harvesting are strictly controlled. In addition, local collection and marketing of medicinal plants and cures may provide income for members of the rural community. This may be threatened by increasing commercialization and demands from urban areas resulting in over-exploitation and erosion of traditional management institutions. Research shows that property rights, both locally and globally in terms of intellectual property rights are extremely important in determining incentives to conserve valuable plants and their habitats.

The example of medicinal plants shows how environmental economics can play a role in many different aspects of the management and use of natural resources. Another important factor is in distinguishing the scale of costs and benefits; this can be illustrated by the tropical forest case: micro (local); meso (national/regional); macro (global). The developed countries naturally tend to put more emphasis on the global value of these resources, (hence the concentration of "global commons" at Rio), and this has implications in terms of policy formulation and implementation, especially in the light of current emphasis on global environmental issues, and the mechanisms for funding conservation.

HAWKS ALOFT WORLDWIDE


By Keith Bildstein

Hawk Mountain Sanctuary, the world's first refuge for birds of prey, was established in 1934 by Rosalie Edge to stop the slaughter of hawks and eagles migrating past a rocky promontory on the Kittatinny Ridge in eastern Pennsylvania. Since its founding, Hawk Mountain Sanctuary has played a key role in protecting North America's raptors and their essential habitats by developing grass-roots support for state and national anti- shooting and habitat-protection legislation.

Today, habitat destruction, environmental contaminants, and shooting continue to plague hawks and eagles elsewhere on their migratory journeys. In an attempt to address these problems -- many of which transcend international boundaries -- Hawk Mountain Sanctuary recently launched Hawks Aloft Worldwide international effort designed to formalize the Sanctuary's long- standing role as informal mentor to raptor conservation organizations and grass-roots activists elsewhere.

Knowing where and how hawks and eagles migrate is an essential prerequisite for their protection. Therefore, in its initial phase, Hawks Aloft Worldwide will identify and compile the first directory and atlas of internationally important hawk and eagle migration sites. Inclusion in the atlas will confer special status to migration sites, thereby strengthening local conservation efforts and stimulating the development of economically viable and ecologically sustainable centers of ecotourism.

It is widely recognized that effective conservation requires the enthusiastic support of domestic conservation organizations and grass-roots activists, and that training for both basic scientists and local conservationists is sorely needed in many countries through which hawks and eagles migrate. Therefore, in its second phase, Hawks Aloft Worldwide will provide training to help local organizations generate competent and productive conservation programs, thereby forging the global grass-roots coalition needed to protect hawks and eagles and their essential habitats throughout their migratory journeys. Given the ambitious nature of this aspect of the project, initial efforts in this area will focus on Latin America.

NEW PUBLICATIONS


The Association of Systematics Collections announces the much awaited Second Edition of Controlled Wildlife I: Federal Permit Procedures, 1992. This guide, revised and updated since the 1984 edition, summarizes in common language the statutes that control the use of wildlife, as well as information on general permit procedures, addresses of key federal agencies, and samples of U.S. and foreign permits. By noting this reference, the book can be purchased for the discount price of $35 (regular price $40), valid through March 31. The original editions of Volume II: Federally Controlled Species, a listing of federally controlled animals and plants and the laws that control their use, and Volume III: State Permit Procedures, state wildlife laws, are still available for $40 each. The whole set - Volumes I, II, and III - is available for $100.

COURSES


The Coastal Resources Center at the University of Rhode Island will be sponsoring a Spanish-language training program, "Manejo de Areas Especiales en Zonas Costeras" April 25 - May 8 at Escuela Superior Politecna del Litoral in Guayaquil, Ecuador. The course will provide participants with practical skills to design and implement special area management plans for coastal areas and environments. Course fee: $1,900 (including food and lodging). For more information, contact: The Training Coordinator, Coastal Resources Center, The University of Rhode Island, Narragansett Bay Campus, Narragansett, RI 92882; Fax: (401) 789-4670.

The Organization for Tropical Studies (OTS) is offering two courses in 1993. The first, "An Intensive Field-oriented Introduction to Tropical Diversity in Rainforest, Seasonally Dry Forest and Cloud Forest Ecosystems", will be conducted August 2-26 in Costa Rica at OTS operated field stations in lowland rainforest (La Selva) and seasonally dry forest (Palo Verde) and at a mid-elevation site (Volcan Cacao in Guanacaste National Park). Enrollment is limited to 22. Applicants are selected on the basis of background and goals related to the objectives of the course. Priority is given to superior applicants who are enrolled in, or accepted for, graduate programs at OTS member institutions. Some slots (about 25%) may be available for students from non-OTS member institutions, as well as recent Ph.D.s who seek professional training in the tropics.
