The golden monkey, Cercopithecus mitis kandti, an Endangered subspecies of blue monkey, is found in only two small populations in the central part of the Albertine Rift region in Central/East Africa.

Dans cette publication, nous faisons le point sur les connaissances et le savoir-faire générés par la première étape du projet, consistant à évaluer les principales menaces qui pèsent sur la biodiversité et à fournir des éléments de réponse aux questions spécifiques suivantes : comment les principales menaces pour la biodiversité ont-elles été identifiées et hiérarchisées, et comment les secteurs associés ont-ils été sélectionnés dans chaque pays ?

Les récentes initiatives mondiales en matière de restauration d’écosystèmes offrent une opportunité sans précédent d’améliorer la conservation de la biodiversité ainsi que la santé et le bien-être humains. Les écosystèmes constituent une composante essentielle de la biodiversité.

Las recientes iniciativas mundiales de restauración de ecosistemas ofrecen una oportunidad sin precedentes para mejorar la conservación de la biodiversidad y la salud y el bienestar humanos. de la biodiversidad. Proporcionan a los seres humanos múltiples beneficios: un clima estable y un aire respirable; agua, alimentos y materiales; y protección contra desastres y enfermedades.

The circular economy is a positive step forward to help achieve our environmental targets. When implemented with nature in mind, it can present an important opportunity for nature and biodiversity. As outlined by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, to halt and reverse biodiversity loss by 2030 we will need to transform our production and consumption systems.

In this publication, we take stock of the knowledge and know-how induced by the BIODEV2030 project’s first step, which is to assess the main threats to biodiversity and provide elements to address the following specific questions: how were main threats to biodiversity identified and ranked and associated sectors selected in each country? Were the different methods converging in identifying top threats?

Connectivity conservation is essential for managing healthy ecosystems, conserving biodiversity and adapting to climate change across all biomes and spatial scales. Well-connected ecosystems support a diversity of ecological functions such as migration, hydrology, nutrient cycling, pollination, seed dispersal, food security, climate resilience and disease resistance.

Com base no volume de rejeitos lançados e na extensão das áreas atingidas, o rompimento da Barragem de Fundão, em Mariana, Minas Gerais, foi o maior desastre ambiental de todos os tempos na mineração brasileira, e um dos mais graves do mundo. Ao serem transportados a jusante da barragem rompida, os rejeitos foram se acumulando ao longo dos rios e alcançaram o estuário do Rio Doce, na ecorregião marinha do Leste brasileiro, afetando importantes ecossistemas.

Based on the volume of tailings releases and the distance they travelled, the Fundão Dam failure in southeast Brazil (Mariana, Minas Gerais state) was the largest ever environmental disaster in Brazil’s mining industry, and one of the world’s most serious. As they dispersed downriver, the tailings accumulated along the riverbanks and reached the Rio Doce estuary in the Eastern Brazilian Marine Ecoregion.

Given the vital role of power lines for social development, the rapid spread of such infrastructure worldwide and the fact that power lines can be one of the main causes of direct mortality for several species of birds and other wildlife, including mammals, it is essential to have suitable tools to ensure that these lines are built and maintained in accordance with environmentally friendly principles, and that priority is given to avoiding and reducing negative impact
