A recent comment piece in Nature argues that Other Effective area-based Conservation Measures (OECMs) provide a mechanism to support effective biodiversity conservation, while protecting the rights and livelihoods of local & Indigenous communities.

OECMs are designated areas that are achieving the effective in-situ conservation of biodiversity outside of protected areas. The guiding principles, common characteristics and criteria for the identification of OECMs were agreed in 2018 by Parties to the Convention on Biological Diversity (CBD)

Biodiversité, bienfaits pour nous

Filtration de la pollution dans l'eau et l'air, régulation du climat, bienfaits psychiatriques, lutte contre les épidémies... la nature rend une multitude de services, souvent ignorés, aux humains. Autant d'arguments pour la préserver.

La biodiversité, mal connue et mal préservée. Par Olivier Monod; Peu rentable, la recherche de nouvelles espèces animales et végétales souffre de manque de moyens. Si les chiffres du nombre d'espèces connues divergent selon les scientifiques, une chose est certaine : plus le temps passe, moins il y en aura à découvrir.

Although humans have long been predators with enduring nutritive and cultural relationships with their prey, seldom have conservation ecologists considered the divergent predatory behavior of contemporary, industrialized humans. Recognizing that the number, strength and diversity of predator-prey relationships can profoundly influence biodiversity, here we analyze humanity’s modern day predatory interactions with vertebrates and estimate their ecological consequences. Analysing IUCN ‘use and trade’ data for ~47,000 species, we show that fishers, hunters and other animal collectors prey on more than a third (~15,000 species) of Earth’s vertebrates. Assessed over equivalent ranges, humans exploit up to 300 times more species than comparable non-human predators.

Coral reefs are home to over a quarter of all ocean life. They are also a source of food, livelihoods, and cultural heritage for 500 million people, and protect coastlines and communities from storms and erosion. Our work is guided by science, and since the original 50 Reefs study, we have produced a number of reports to inform our coral conservation efforts.

The projected loss of millions of square kilometres of natural ecosystems to meet future demand for food, animal feed, fibre and bioenergy crops is likely to massively escalate threats to biodiversity. Reducing these threats requires a detailed knowledge of how and where they are likely to be most severe. We developed a geographically explicit model of future agricultural land clearance based on observed historical changes, and combined the outputs with species-specific habitat preferences for 19,859 species of terrestrial vertebrates.
