SummaryThe Houbara Bustard Chlamydotis undulata is prominent in avian conservation because of its high value as the traditional quarry of falconers in Arabia and western Asia; such hunting has often been blamed for severely reducing population levels especially in Arabia, Pakistan and Morocco. This paper reviews current knowledge of the world status of the Houbara Bustard in each of the 31 range states where it has occurred within the last 10 years. On the basis of the evidence available, the overall population is estimated to be between 49,000 and 62,000 birds, made up of 700–750 birds in the Canary Islands, around 10,000 in Africa, and the remainder in the Middle East and Asia (especially Iran, Kazakhstan, Uzbekistan and Turkmenistan). Numbers have apparently declined greatly during this century because of agricultural intensification and other land use changes, often exacerbated by hunting and trapping. Evaluation of the population status and trends against the current Red List criteria of IUCN indicate that the Canary Islands subspecies C. u. fuertaventurae is Vulnerable, while the subspecies C. u. undulata and C. u. macqueenii (as well as the whole species population) could probably also qualify for listing as Vulnerable but it is more appropriate to consider them “Near threatened” for the time being.
In the Anthropocene, marine ecosystems are rapidly shifting to new ecological states. Achieving effective conservation of marine biodiversity has become a fast‐moving target because of both global climate change and continuous shifts in marine policies. How prepared are we to deal with this crisis? We examined EU Member States Programs of Measures designed for the implementation of EU marine environmental policies, as well as recent European Marine Spatial Plans, and discovered that climate change is rarely considered operationally. Further, our analysis revealed that monitoring programs in marine protected areas are often insufficient to clearly distinguish between impacts of local and global stressors. Finally, we suggest that while the novel global Blue Growth approach may jeopardize previous marine conservation efforts, it can also provide new conservation opportunities. Adaptive management is the way forward (e.g., preserving ecosystem functions in climate change hotspots, and identifying and targeting climate refugia areas for protection) using Marine Spatial Planning as a framework for action, especially given the push for Blue Growth.
As a response to increasing human pressures on marine ecosystems, the legislation aimed at improving the conservation and management of marine coastal areas in European and Contiguous Seas (ECS) underwent crucial advances. ECS, however, still remain largely affected by increasing threats leading to biodiversity loss. Here, by using emblematic case studies and expert knowledge, we review current conservation tools, comparing their application in different areas to assess their effectiveness, potential for synergies, and contradictions. Despite regional differences in their application, the existing legislative frameworks have the potential to regulate human activities and to protect marine biodiversity. However, four challenges remain to be addressed to fully achieve environmental policy goals: (1) Lack of shared vision representing a limitation in transboundary collaboration. Although all EU countries are committed to fulfil EU Directives and other binding international legislative acts, a remarkable heterogeneity exists among countries in the compliance with the common legislation on conservation and in their degree of implementation. (2) Lack of systematic procedures for the selection of protected marine sites. Regional and national approaches in designating Natura
HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
