Suitability determining in protected area for wildlife (Case study: Geno protected area)
Introduction: Rangelands constitute almost 52 percent of the country area computed as 164 million ha. The extent of rangelands has been estimated 84 million ha in Iran and they have been classified as good, moderate to poor and poor to very poor ones ranged as almost 10, 42 and 48 percent, respectively. One of the fundamental problems concerning land uses of rangelands is that Rangeland are not...
متن کاملStepwise strategic environmental management in marine protected area
In recent decades, necessity to protect environment has been a serious concern for all people and international communities. In appropriate development of human economic activities, subsistence dependence of the growing world population on nature decreases the natural diversity of ecosystems and habitats day by day and provides additional constraints for life and survival of wildlife.

متن کاملBiogeographic Assessments: Integration of Ecology and Gis to Define and Evaluate Marine Protected Area Boundaries
The world’s marine resources face multiple stresses from both human activities and natural environmental perturbations. As pressures on marine resources continue to increase, it has become evident that data required to make informed management decisions, bounded by policy aspects, are either lacking or not easily accessed (Battista and Monaco 2004). Information technologies provide a suite of c...
متن کاملGlobal protected area impacts
Protected areas (PAs) dominate conservation efforts. They will probably play a role in future climate policies too, as global payments may reward local reductions of loss of natural land cover. We estimate the impact of PAs on natural land cover within each of 147 countries by comparing outcomes inside PAs with outcomes outside. We use 'matching' (or 'apples to apples') for land characteristics...
متن کاملStudy of Grazing Conflicts in Protected Areas (case study: Bahram-e Goor protected area in Fars province)
Protected areas have emerged as one of the most important and effective tools in the world for biodiversity conservation. Changing the use of natural lands, especially rangelands to protected areas, causes livestock grazing to be restricted in some of the grazing lands. These restrictions cause conflict between different natural land stakeholders. This study investigates the grazing management ...
