Ecosystems and Human Well-Being: Biodiversity Synthesis ecosystemshumanw05kuma Year: 2005 biodiversity. PAs need to be better located, designed, and man- aged to deal with problems like lack of representativeness, impacts of human settlement within protected areas, illegal har- vesting of plants and animals, unsustainable tourism, impacts of invasive species, and vulnerability to global change. Marine and freshwater ecosystems are even less well protected than terrestrial ones, although new developments in marine protected areas and PA networks show promise. Marine protected areas often provide striking examples of the potential synergies between conservation and sustainable use, since appropriately placed ones can signifi- cantly increase fishery harvests in adjoining areas. In all cases, better policy and institutional options are needed to promote the fair and equitable sharing of costs and benefits of protected areas at all levels. â Species protection and recovery measures for threatened species. Considerable scope exists to conserve and use biodiversity sus- tainably through more effective management of individual species. Although 'habitat-based' approaches to species conser- vation are critical, they are by no means a replacement for 'spe- cies-based' approaches, and likewise, species-based approaches are insufficient for habitat conservation. â Ex situ and in situ conservation of genetic diversity. The bene- fits from ex situ conservation of genetic diversity, such as gene- banks, are substantial. While the technology continues to improve, the major constraint is ensuring that an adequate range of genetic diversity is contained within the ex situ facilities and that these remain in the public domain where, for example, they can serve the needs of poor farmers. In addition, significant ben- efits can be gained through better integration of ex situ and in situ conservation strategies, particularly for species that are difficult to maintain in ex situ faci
