Processes of wetland loss in India
Environmental Conservation - Tập 23 Số 1 - Trang 45-54 - 1996
SummaryWetlands in India supply crucial human and animal needs such as drinking
water, protein production, fodder, water purification, wildlife habitat, and
flood storage. Increased appreciation of uses and threats is essential to
protect wetlands where justified. Three quarters of India's population is rural,
it places great demands on India's wetlands and losses continue to occur. This
paper is ...
A review of methods for the assessment of prediction errors in conservation presence/absence models
Environmental Conservation - Tập 24 Số 1 - Trang 38-49 - 1997
Predicting the distribution of endangered species from habitat data is
frequently perceived to be a useful technique. Models that predict the presence
or absence of a species are normally judged by the number of prediction errors.
These may be of two types: false positives and false negatives. Many of the
prediction errors can be traced to ecological processes such as unsaturated
habitat and speci...
Sustainability science: a review, an analysis and some empirical lessons
Environmental Conservation - Tập 38 Số 3 - Trang 275-287 - 2011
SUMMARYSustainability science has developed from a new research field into a
vibrant discipline in its own right, with scientific conferences, journals and
scientific societies dedicated to its pursuit. Characterized more by its
research purpose than by a common set of methods or objects, sustainability
science can be subdivided into the more traditional disciplinary-based science
for sustainabili...
Factors influencing success among collaborative sage-grouse management groups in the western United States
Environmental Conservation - Tập 37 Số 3 - Trang 250-260 - 2010
SUMMARYConsiderable efforts have been put into collaborative conservation
efforts across the globe. In the western USA, concern about declines of two
sage-grouse species (Centrocercus urophasianus and C. minimus) has led to the
creation of over 60 collaborative wildlife management partnership groups to
develop and implement local sage-grouse management plans. These sage-grouse
local working groups...
Threats to the running water ecosystems of the world
Environmental Conservation - Tập 29 Số 2 - Trang 134-153 - 2002
Running waters are perhaps the most impacted ecosystem on the planet as they
have been the focus for human settlement and are heavily exploited for water
supplies, irrigation, electricity generation, and waste disposal. Lotic systems
also have an intimate contact with their catchments and so land-use alterations
affect them directly. Here long-term trends in the factors that currently impact
runni...
Resources use, conservation attitudes, management intervention and park-people relations in the Western Terai landscape of Nepal
Environmental Conservation - Tập 34 Số 1 - Trang 64-72 - 2007
Various conservation models have been implemented in Nepal since 1973, however
their impacts on resources use and conservation attitudes are scarcely known. To
address the hypothesis that conservation attitudes should improve around
protected areas (PAs) with more social and economic interventions, stratified
random questionnaire surveys of 234 households were conducted in two PAs in the
Western T...
Heavy-metal Pollution in the Sudbury Mining and Smelting Region of Canada, I. Soil and Vegetation Contamination by Nickel, Copper, and Other Metals
Environmental Conservation - Tập 1 Số 2 - Trang 123-132 - 1974
Soil, vegetation, and rainfall, have been collected in the vicinity of a
nickel–copper smelter at Sudbury, Ontario. The region is a major producer of
many metals, and the large areas of forest desolation in the vicinity have been
ascribed to sulphur dioxide fumigations over the past 80 years. In the present
study, attention has been focused on potentially toxic heavy metals. Very
elevated soil lev...
Biophysical and policy drivers of landscape change in a central Vietnamese district
Environmental Conservation - Tập 34 Số 2 - Trang 164-172 - 2007
Conservation in a dynamic setting requires understanding the factors leading to
landscape change. This study integrated traditional remote sensing and
geographic information systems analysis techniques with a narrative policy
analysis to assess the 1975–2004 land cover changes and their determinants in
Nam Dong district (central Vietnam). Total forest cover of Nam Dong remained
stable, but there w...
The continental shelf benthic ecosystem: current status, agents for change and future prospects
Environmental Conservation - Tập 29 Số 3 - Trang 350-374 - 2002
Continental shelf benthic ecosystems play an important role in the economy of
many coastal states through the provision of food, non-living resources and
through control of climate. Changes in the status of these ecosystems, through
either natural or human-induced environmental drivers can be expected to have
important economic and social consequences. Agents that could induce change
include clima...
Effects of rainfall and grazing on vegetation yield and cover of two arid rangelands in Kuwait
Environmental Conservation - Tập 24 Số 4 - Trang 344-350 - 1997
Increasing human pressure has presumably led to a decrease in the cover and
herbage yield of Kuwaiti desert vegetation, but, to date, there has been little
detailed study on such human impacts. A study of Rhanterium epapposum (local
name arfaj) and Haloxylon salicornicum (local name remeth) steppe was therefore
effected to determine the seasonal variation in above-ground phytomass and
percentage c...
