Effectiveness of parks in protecting tropical biodiversity.
We assessed the impacts of anthropogenic threats on 93 protected areas in 22 tropical countries to test the hypothesis that parks are an effective means to protect tropical biodiversity. We found that the majority of parks are successful at stopping land clearing, and to a lesser degree effective at mitigating logging, hunting, fire, and grazing. Park effectiveness correlates with basic managem...
متن کاملProtecting ecosystem services and biodiversity in the world’s watersheds
Despite unprecedented worldwide biodiversity loss, conservation is not at the forefront of national or international development programs. The concept of ecosystem services was intended to help conservationists demonstrate the benefits of ecosystems for human well-being, but services are not yet seen to truly address human need with current approaches focusing mostly on financial gain. To promo...
متن کاملProtecting Biodiversity when Money Matters: Maximizing Return on Investment
BACKGROUND Conventional wisdom identifies biodiversity hotspots as priorities for conservation investment because they capture dense concentrations of species. However, density of species does not necessarily imply conservation 'efficiency'. Here we explicitly consider conservation efficiency in terms of species protected per dollar invested. METHODOLOGY/PRINCIPAL FINDINGS We apply a dynamic ...
متن کاملWATER MANAGEMENT AND BIODIVERSITY : The opportunity cost of protecting biodiversity in a Mediterranean delta . DRAFT
In wetlands, hydrology is a driving factor in all ecological economic interactions. Any attempt at water management for human activities will alter the balance of these interactions, and may threaten sustainable use of wetland resources. The Camargue is an extensive area of wetland (80 000 ha) in the Rhône delta in the South of France, where hydrology has long been influenced by man. The intera...
متن کاملIncorporating Conservation Zone Effectiveness for Protecting Biodiversity in Marine Planning
Establishing different types of conservation zones is becoming commonplace. However, spatial prioritization methods that can accommodate multiple zones are poorly understood in theory and application. It is typically assumed that management regulations across zones have differential levels of effectiveness ("zone effectiveness") for biodiversity protection, but the influence of zone effectivene...
