The concept of biodiversity, its introduction in conservation biology, and its evolution in the framework of systematic conservation planning, are analyzed. Attempts to quantify biodiversity and to find surrogate measures for it are described. It is shown that biodiversity originated as and remains a fundamentally normative concept. However, while attempts to reduce biodiversity conservation to...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
Conservation scientists, national governments, and international conservation groups seek to devise, and implement, governance strategies that mitigate human impact on the environment. However, few studies to date have systematically investigated the performance of different systems of governance in achieving successful conservation outcomes. Here, we use a newly-developed analytic framework to...
Recognizing the imperiled status of biodiversity and its benefit to human well-being, the world's governments committed in 2010 to take effective and urgent action to halt biodiversity loss through the Convention on Biological Diversity's "Aichi Targets". These targets, and many conservation programs, require monitoring to assess progress toward specific goals. However, comprehensive and easily...
Independently owned nature reserves are proliferating across the developing world. Nevertheless, the conservation community knows practically nothing about them. This paper examines the economic, ecological, and social impacts of ecotourism, as evidenced at thirty-two of these reserves. Ecotourism is shown to be the primary means through which reserves survive financially. This reliance provide...
participatory conservation, as bottom-up management, is currently the most acceptable modelfor management of protected areas across the world. social context is a central issue in the sustainablemanagement of conservation areas. it is also crucial to introducing participatory conservation. the newapproach therefore recognizes rural communities as key partners in biodiversity management and seek...
Ecosystem management involves long-term management of whole ecosystems, across political boundaries as necessary, to sustain ecosystem integrity. The conservation biology view of ecosystem management tends to be biocentric, placing primary emphasis on sustaining the integrity of natural ecosystem processes and native species. The US Forest Service favors an anthropocentric approach in which an ...
FOREWORD The impact of environmental weeds on the natural environment is an area that has been little studied in Australia. More often than not, impact is assumed rather than quantified. If the impact of environmental weeds on nature conservation values is not quantitatively assessed before a control program is begun, valuable resources can be wasted. For instance, how would it be possible to d...
