Key Biodiversity Areas (KBAs)

L’Afrique occidentale est riche en biodiversité d’eau douce et en endémicité régionale, soutenant l’ensemble des populations mondiales de nombreuses espèces d’eau douce menacées, notamment les poissons, les mollusques, les libellules, les crabes, les crevettes et les plantes aquatiques. Ce rapport s’appuie sur une évaluation de référence régionale réalisée en 2009 ainsi que sur une évaluation des Zones clés pour la biodiversité (KBAs) d’eau douce en 2015.

Western Africa is rich in freshwater biodiversity and regional endemicity, supporting the entire global populations of many threatened freshwater species including fishes, molluscs, dragonflies, crabs, shrimps and aquatic plants. This report builds on a regional baseline assessment completed in 2009 as well as an assessment of freshwater Key Biodiversity Areas in 2015.

Key Biodiversity Areas (KBAs) are sites that contribute significantly to the global persistence of biodiversity. The purpose of the Guidelines for using A Global Standard for the Identification of Key Biodiversity Areas is to ensure that KBA identification is based on consistent, scientifically rigorous yet practical methods.

As presentes Directrizes sobre Negócios e KBAs foram desenvolvidas pelos Parceiros das KBAs para apoiar as empresas na gestão de riscos para a biodiversidade. Serão úteis para operadores económicos e de regimes de certificação, instituições financeiras, organizações da sociedade civil e autoridades públicas.

The World Heritage thematic study for Central Asia has been produced as a contribution to supporting the implementation of the World Heritage Convention in Central Asia. It provides a response to a Decision of the World Heritage Committee in order to identify outstanding areas with potential for future nomination to the World Heritage List with primary focus on criteria (ix) and (x) at the regional scale.

The Lake Malawi/Nyasa/Niassa Catchment (LMNNC) supports exceptionally high diversity and endemism of freshwater species. This globally recognised centre of freshwater biodiversity is of extreme importance, not only for its biodiversity value but also for our understanding of evolutionary processes and species sorting.

In 2011, the government of Germany and IUCN together launched the Bonn Challenge as a global commitment to bring under restoration 150 million hectares (Mha) of land by 2020.  IUCN has developed the Bonn Challenge Barometer: a progress-tracking framework and tool to support pledgers in meeting the critical need to assess and report on the implementation of national and subnational forest landscape restoration (FLR) pledges made under the Bonn Challenge.

The purpose of these guidelines is to ensure that Key Biodiversity Area (KBA) identification is based on consistent, scientifically rigorous yet practical methods. The KBA Guidelines provide an overview of the steps for identifying and delineating KBAs, together with explanation of how the KBA criteria, thresholds and delineation procedures should be applied in practice.

The Mediterranean region is one of the world’s great centres of plant diversity and its benign climates have attracted successive waves of civilisations, which have largely shaped our attitudes and ethics to the present day. Despite the effects of grazing, agriculture, deforestation, pollution, urbanisation and tourism, it has developed a wide array of plant landscapes.

Increasing interest in measuring, modelling and valuing ecosystem services (ES), the benefits that ecosystems provide to people, has resulted in the development of an array of ES assessment tools in recent years. Selecting an appropriate tool for measuring and modelling ES can be challenging.
