This set of papers presents a description of the synthesis of hydrological problems and various environmental implications and management strategies for different highland and headwater regions of the world. Regions covered include the Himalayas, Russian mountains, Amazonia, and upland Wales.
The Kejimkujik Watershed Study (KWS) was initiated in 1978 in response to growing concerns about the possible harmful effects on the environment of long range transport of air pollutants, particularly acid rain. It is one of five calibrated watershed studies in Canada that represent a range of climatic conditions, terrain sensitivities, and rates of atmospheric acidic deposition. This report presents the proceedings of a workshop on the study, covering programs and concepts in integrated monitoring and research; monitoring global change; research and monitoring in and around Kejimkujik National Park; monitoring and research of surface waters, lakes and streams, and forests and watersheds; and the organization and interpretation of Kejimkujik research station establishment. Summary reports are given on watershed studies in the Experimental Ponds Area of Newfoundland, the Integrated Forest Studies Cooperative in Vermont, and the Humic Lake acidification experiment in Norway. Highlights of an open discussion on future activities are also included.
A Century of Maritime Science reviews the fisheries, environmental, oceanographic, and aquaculture research conducted over the last hundred years at St. Andrews from the perspective of the participating scientists.
Politics of the Wild details the 353 species at risk in Canada and considers both the intrinsic and the instrumental reasons for protecting biological diversity. It examines the need for habitat protection, terrestrial protected areas such as national parks, marine species at risk, and the various legislative and interest group attempts to preserve biodiversity. Public policy on endangered species is considered from both historical and comparative perspectives, as is Canada's role in establishing international agreements--the Convention on International Trade in Endangered Species and the Convention on Biological Diversity--and the government's failure in recent years to meet the obligations of these and other environmental agreements. The final chapter looks at the Species at Risk Act (SARA) and its recent predecessor, Bill C-65, and reveals the difficulties of crafting and passing such legislation in an increasingly decentralized federal state such as Canada. Both legislative attempts were criticized--by the environmental policy community for not doing enough, and by the provinces and business for trying to do too much. All the while, diverse regional interests and economic imperatives run the risk of endangering far more than merely Canadian species at risk.
This document is a comprehensive statement of broad principles that give direction both to present programs and future initiatives of Parks Canada. It provides a framework for the delivery of heritage programs and for responsible management decisions that reflect the national interest while being sensitive to local considerations. It explains how the federal government, within the context of Parliamentary approvals, carries out its national programs of natural and cultural heritage recognition and protection as assigned to the Minister responsible for Parks Canada.
As rising levels of mercury in the environment pose an increasing threat of toxicity to humans and wildlife, several laws already call for industries to reduce mercury emissions at the source. Ecosystem Responses to Mercury Contamination: Indicators of Change outlines the infrastructure and methods needed to measure, monitor, and regulate the conce
