Integrating regional conservation priorities for multiple objectives into national policy
Multinational conservation initiatives that prioritize investment across a region invariably navigate trade-offs among multiple objectives. It seems logical to focus where several objectives can be achieved efficiently, but such multi-objective hotspots may be ecologically inappropriate, or politically inequitable. Here we devise a framework to facilitate a regionally cohesive set of marine-pro...
متن کاملTropical Agricultural Production, Conservation and Carbon Sequesteration Conflicts: Oil Palm Expansion in South East Asia
Agricultural expansion remains one of the leading causes of deforestation, biodiversity losses and environmental degradation across the world, especially in the tropics (Angelsen et al., 1999 and Norris, 2008). From 1961 to 1993, the world population increased by 80% (Goklany, 1998). Due to the rapidly expanding human populations large increases in the supply of agricultural products are requir...
متن کاملIntegrating Economic Costs and Biological Traits into Global Conservation Priorities for Carnivores
BACKGROUND Prioritization schemes usually highlight species-rich areas, where many species are at imminent risk of extinction. To be ecologically relevant these schemes should also include species biological traits into area-setting methods. Furthermore, in a world of limited funds for conservation, conservation action is constrained by land acquisition costs. Hence, including economic costs in...
متن کاملCrop Expansion and Conservation Priorities in Tropical Countries
Expansion of cropland in tropical countries is one of the principal causes of biodiversity loss, and threatens to undermine progress towards meeting the Aichi Biodiversity Targets. To understand this threat better, we analysed data on crop distribution and expansion in 128 tropical countries, assessed changes in area of the main crops and mapped overlaps between conservation priorities and cult...
متن کاملBiogeography and Conservation
There is hardly a region in the world where mycoheterotrophy does not occur. As far as we know, all orchid species are dependent on fungi during germination and early development and are therefore classi fi ed as initial mycoheterotrophs (Chap. 1 ). Orchidaceae have a worldwide distribution and occur in almost every terrestrial ecosystem apart from deserts and permafrosts. The distribution of f...
