Since about 1600, 486 animal species have been recorded extinct. This represents about 0.04 of all animal species so far described. In the same period, 600 plant species are known to have disappeared, about 0.25 of the total. These figures are much smaller than those of the Permian/Triassic and Cretaceous/Tertiary mass extinctions. One might therefore conclude that at present life on earth is at comparatively little risk of extinction. However, there is a growing body of data to show that the converse is true.
Resource Type: Journal PapersWe made a complete survey of all the extant populations in Djibouti and to collect samples for genetic analysis with a view conserving the palm for the future.
Our survey revealed that there were a total of 314 adults, 20 juveniles, 134 rosettes, 210 small rosettes (more than 6 leaves) and 465 seedlings (<3 leaves) living in the Bankouale area of Djibouti. These are distributed unequally amongst three valley systems. 65% of the adults, 85% of the juveniles, 75% of the rosettes, 76% of the small rosettes, and 93 % of the seedlings were found in the Bankouale valley.
Advice on assessment of biodiversity impacts is required to support trade negotiations and reduce risks of unforeseen consequences for important biodiversity and those who depend on it for their livelihoods. This paper explores linkages between biodiversity and trade and draws on examples from the agriculture sector to reinforce the need to build a biodiversity-inclusive process for as-sessing impacts of trade policies and agreements.
Resource Type: Journal PapersMoving beyond 2010, successful conservation approaches need to be reinforced and adequately financed. More radical changes are required that recognize biodiversity as a global public good, that integrate biodiversity conservation into policies and decision frameworks for resource production and consumption, and that focus on wider institutional and societal changes to enable more effective implementation of policy.
Resource Type: Journal PapersAmong the crucial problems that affect conservation in less developed countries are the high human pressure on natural habitats, poverty, low conservation education and lack of integration of local population. However, political and ethnic conflicts, which occur around the world and particularly in African countries, significantly affect all sectors of human society, the environment and wildlife. In this paper, we discuss the consequences of the Rwandan civil war of 1990–1994, recognized as one of the major tragedies of the 20th century, with a particular focus on protected areas and conservation bodies in the country.
Resource Type: Journal PapersSmall local hunting communities in Siberia are very distant from any governmental control. Hunted waterbird species, including globally and regionally threatened species, rely for their well-being on the self regulation of remote hunting communities. Interviewed hunters showed a profound knowledge of Baikal Teal, its population status, and the causes of their past decline. Whether the knowledge is shared by other communities in the region and beyond in Northern Siberia needs verification.

The United Nations Framework Convention on Climate Change (UNFCCC) is currently discussing the development of a mechanism for reducing emissions from deforestation in developing countries (RED). An effective RED mechanism could provide an unprecedented opportunity to contribute towards the goals of a range of multilateral environmental agreements and mechanisms, including the Convention on Biological Diversity (CBD), by helping to ensure that forests continue to provide vital ecosystem services, conserve biodiversity, and enhance livelihoods. The design and implementation of the mechanism will affect the degree to which these other benefits are obtained.
Resource Type: Journal PapersGovernments are often accused of responding only to short-term and parochial considerations. It is therefore remarkable that representatives of 190 countries recently committed themselves at the Convention on Biological Diversity to reducing biodiversity loss. This presents conservation biologists with perhaps their greatest challenge of the decade. The authors of this Policy Forum describe approaches to identifying more of the earth's biological diversity; understanding how biological, geophysical, and geochemical processes interact; and presenting scientific knowledge in time to contribute to and achieve the 2010 target.
Resource Type: Journal PapersSustainability requires living within the regenerative capacity of the biosphere. In an attempt to measure the extent to which humanity satisfies this requirement, we use existing data to translate human demand on the environment into the area required for the production of food and other goods, together with the absorption of wastes. Our accounts indicate that human demand may well have exceeded the biosphere's regenerative capacity since the 1980s. According to this preliminary and exploratory assessment, humanity's load corresponded to 70% of the capacity of the global biosphere in 1961, and grew to 120% in 1999.
Resource Type: Journal PapersWe suggest that well-targeted instruments that consider contextual information, such as conservation status, are the most effective and efficient approach to monitoring international wildlife trade for conservation purposes. Where relevant, such instruments could be expanded to include additional species not currently protected, or new instruments could be developed to monitor certain groups as appropriate.
