Focusing on the rich biodiversity of Costa Rica, the contributors demonstrate the use of geographic information systems (GIS) to enhance conservation efforts. They give an overview of the spatial nature of conservation and management and the current status of digital mapping in Costa Rica; a review of the basic principles behind digital mapping technologies; a series of case studies using these technologies at a variety of scales and for a range of conservation and management activities; and the results of the Costa Rican gap analysis project....
Following its establishment in 1987,the IUCN Botanic
Gardens Conservation Secretariat (BGCS) began to
build its membership of botanic gardens worldwide
and develop a programme of activities in support of
botanic gardens. In 1989,The Botanic Gardens
Conservation Strategy was published and the
following year BGCS became independent from
IUCN, and subsequently known as Botanic Gardens
Conservation International (BGCI). BGCI registered
as a U.K.charity and received the support of HRH
The Prince of Wales as its Royal Patron.
Few issues display more clearly the competition between China’s drive to
become economically developed and to conserve biodiversity than hydropower
development. This is the subject of China’s most recent environmental
controversy. In August 2003, the National Development and Reform
Commission, a powerful economics super-ministry, authorized construction of
a 13-station dam along the Nu1 River (Nujiang) in Yunnan Province. After at
least a decade of construction, the dam would become the world’s largest.
Research in tropical forestry is confronted with the task of finding strategies to alleviate pressure on remaining forests, and techniques to enhance forest regeneration and restore abandoned lands, using productive alternatives that can be attractive to local human populations. In addition, sustainable forestry in tropical countries must be supported by adequate policies to promote and maintain specific activities at local and regional scales.
Natural resources conservation is one of the dilemmas currently facing mankind in both developed and the developing world. The topic is of particular importance for the latter, where the majority depend on terrestrial ecosystems for livelihood; more than one billion people live in abject poverty earning less than a dollar per day; more than 3.7 billion suffer from micronutrient deficiency and more than 800 million suffer from chronic hunger.
Thin-film science and technology play a crucial role in the high-tech industries
that will bear the main burden of future American competitiveness. While the
major exploitation of thin films has been in microelectronics, there are
numerous and growing applications in communications, optical electronics,
coatings of all kinds, and in energy generation and conservation strategies.
The two notions appeared simultaneously around the 1970s. The concept of
strategic scanning first appeared in 1967 with the publication of the founding work
by Aguilar entitled Scanning the Business Environment. The origin of the idea of
sustainable development dates back to 1970, when first Ignacy Sachs and then the
international conference of Stockholm (in 1972) proposed the concept of
In January 1976, the Transportation Energy Conservation (TEC) Division of the Energy
Research and Development Administration contracted with Oak Ridge National Laboratory
(ORNL) to prepare a Transportation Energy Conservation Data Book to be used by TEC staff in
their evaluation of current and proposed conservation strategies. The major purposes of the Data
Book were to draw together, under one cover, transportation data from diverse sources, to
resolve data conflicts and inconsistencies, and to produce a comprehensive document.
Conserving Living Natural Resources provides students, managers, and general readers with an
introduction to the principles of managing biological resources. It presents the historical and
conceptual contexts of three seminal approaches to the management of living natural
resources: utilitarian management for harvest of featured species and control of unwanted
species, protection and restoration of populations and habitats to maintain biodiversity, and
management of complex ecosystems to sustain both productivity and biodiversity.
This study looks at whether Vietnam could adopt the Payment for Environmental Services (PES) approach as part of its national conservation strategy. Using a pilot study in the country’s uplands, it investigates how such a scheme might run and assesses its impact on the environment and on the local people’s livelihoods. Through a review of current Vietnamese conservation practice, it assesses the barriers to the adoption of such schemes and the factors that might encourage their implementation....
Almost 75 percent of the elderly (age 65 and over) have at
least one chronic illness.3 About 50 percent have at least
two chronic illnesses.3 Chronic conditions can lead to
severe and immediate disabilities, such as hip fractures and
stroke, as well as progressive disability that slowly erodes
the ability of elderly people to care for themselves.4
According to AHRQ’s 1996 Medical Expenditure Panel
Survey (MEPS),a about 14.3 percent of people age 65 and
over—4.5 million elderly Americans—require assistance
with bathing, dressing, preparing meals, or shopping.
As currently taught, the introductory course in analytical chemistry emphasizes
quantitative (and sometimes qualitative) methods of analysis coupled with a heavy
dose of equilibrium chemistry. Analytical chemistry, however, is more than equilib-
rium chemistry and a collection of analytical methods; it is an approach to solving
chemical problems. Although discussing different methods is important, that dis-
cussion should not come at the expense of other equally important topics.
The Company seeks to provide a comprehensive range of sub-funds with the purpose of spreading investment risk and satisfying the
requirements of investors seeking income, capital conservation and growth.
In carrying out the investment objectives of the Company, the Board of Directors at all times seeks to maintain an appropriate level of
liquidity in the assets of the sub-funds so that redemptions of Shares under normal circumstances may be made without undue delay
upon request by shareholders.

This course covers geologic and engineering concepts, methodology, and technology used to characterize, evaluate and manage naturally-fractured reservoirs. Applications and limitations of geologic and engineering procedures and tools are discussed. Field examples and case studies demonstrate the importance of integrated geologic and engineering studies in developing effective, economical reservoir management strategies for different types of reservoirs.
Protected areas remain the fundamental building blocks of virtually
all national and international conservation strategies, supported by
governments and international institutions such as the Convention
on Biological Diversity.
