  Gulf pollution - how bad is it? »

  The Gulf War will cause major environmental effects that may be felt well beyond the boundaries of the countries involved. Hostilities could result in an international environmental disaster affecting the land, sea and atmosphere. Throughout the Gulf region and specifically the three countries of Kuwait, Iraq and Saudi Arabia there are a total of more than 3,650 animal species. Of these, some 50 are recognised internationally as being threatened with extinction. These include 20 species of bird, 20 mammal species, three reptiles, two fishes, four molluscs and one insect.

  Progress towards the Convention on Biological Diversity terrestrial 2010 and marine 2012 targets for protected area coverage »

  In the past few years, a number of analyses have been undertaken to measure progress towards the 2010 and 2012 CBD targets. This report demonstrates how the measurement of progress is influenced by decisions on which protected areas are included (for instance, whether internationally designated sites, or sites without an assigned IUCN category are included) and which biogeographic datasets used (for instance which mountain dataset is chosen), and highlights the need for standardised methods and datasets.

  Economic Reasons for Conserving Wild Nature »

  On the eve of the World Summit on Sustainable Development, it is timely to assess progress over the 10 years since its predecessor in Rio de Janeiro. Loss and degradation of remaining natural habitats has continued largely unabated. However, evidence has been accumulating that such systems generate marked economic benefits, which the available data suggest exceed those obtained from continued habitat conversion. We estimate that the overall benefit:cost ratio of an effective global program for the conservation of remaining wild nature is at least 100:1.

  Prospects for Biodiversity »

  Assuming no radical transformation in human behavior, we can expect important changes in biodiversity and ecosystem services by 2050. A considerable number of species extinctions will have taken place. Existing large blocks of tropical forest will be much reduced and fragmented, but temperate forests and some tropical forests will be stable or increasing in area, although the latter will be biotically impoverished. Marine ecosystems will be very different from today's, with few large marine predators, and freshwater biodiversity will be severely reduced almost everywhere. These changes will not, in themselves, threaten the survival of humans as a species.

  How much do we know about the current extinction rate? »

  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.

  Physiographic control on the development of Spartina marshes »

  We 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.

  Assessing biodiversity impacts of trade: a review of challenges in the agriculture sector »

  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.

  Biodiversity Conservation: Challenges beyond 2010 »

  Moving 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.

  Impact of war on conservation: Rwandan environment and wildlife in agony »

  Among 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.

  Status of the Baikal Teal in the Lower Indigirka Basin, Siberia »

  Small 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.
