Resource Type: ReportsWe 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.
This paper reviews the potential for carbon sequestration in dryland ecosystems, which includes forests, but also covers other habitats, such as grasslands, and, importantly, soils. It also considers ways in which carbon storage in drylands affects land degradation issues.
Resource Type: ReportsCoastal and freshwater ecosystems are deteriorating in many areas and at a faster rate than any other ecosystem. Such changes are caused by intertwined factors, making it difficult to identify the problems early on. While progress in integrating these various factors in managing water and ecosystems has been made in some places, the majority of the world and its inhabitants increasingly suffers from a lack of priority given to environmental protection.
Resource Type: ReportsThe Protected Planet Report 2012 reviews progress towards the achievement of international protected area targets.
Resource Type: ReportsSmall 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.

This study demonstrates the utility of carbon isotope discrimination in describing genetic adaptation to arid environments, although it is probably most useful in detecting differentiation when the strategy of the species under investigation is to increase water use efficiency, rather than drought-avoidance. The results suggest that populations on the eastern and western sides of the Andes should be treated as separate management units for the purposes of conserving the genetic resource of this species.
Resource Type: Journal PapersSince the late 1970s the UNEP World Conservation Monitoring Centre (UNEP-WCMC) has delivered services that support implementation of international biodiversity-related agreements at global, regional and national levels. These services not only support the work of the agreement secretariats, but also of the advisory and governance bodies, and of governments party to the various agreements. The aim of this paper is to illustrate this work through examples of work we have undertaken.
The support that UNEP-WCMC provides is based on expert understanding of the agreements and how they work, resulting from many years of experience and close relationships with secretariats.
