To reduce biodiversity loss in Fiji, the BIODEV2030 initiative is exploring how voluntary sectoral commitments can safeguard nature and livelihoods, while contributing to the country’s national biodiversity targets...BIODEV 2030 is helping 16 pilot countries secure voluntary, sector-based commitm

Gains in biodiversity conservation and ecosystem services from the expansion of the planet’s protected areas

Protected areas safeguard biodiversity, ensure ecosystem functioning, and deliver ecosystem services to communities. However, only ~16% of the world’s land area is under some form of protection, prompting international calls to protect at least 30% by 2030. We modeled the outcomes of achieving this 30 × 30 target for terrestrial biodiversity conservation, climate change mitigation, and nutrient regulation.

Lessons learnt in global biodiversity governance

INEA has featured many articles covering the dilemmas, puzzles, and tensions related to global biodiversity governance; this coverage was infrequent in earlier issues but has steadily increased as both environmental diplomacy and international law on biodiversity conservation and environmental justice have expanded. Using the defnition found in the Convention on Biological Diversity, we scanned INEA articles and derived several lessons learnt over the 2000–2020 period.

Improving biodiversity protection through artificial intelligence

Over a million species face extinction, highlighting the urgent need for conservation policies that maximize the protection of biodiversity to sustain its manifold contributions to people’s lives. Here we present a novel framework for spatial conservation prioritization based on reinforcement learning that consistently outperforms available state-of-the-art software using simulated and empirical data.

A Typology for Reef Passages

Coral reefs host exceptionally diverse and abundant marine life. Connecting coasts and sheltered lagoons to the open ocean, reef passages are important yet poorly studied components of these ecosystems. Abiotic and biotic elements ‘pass’ through these reef passages, supporting critical ecological processes (e.g. fish spawning). Reef passages provide multiple social and ecological benefits for islands and their peoples, but are so far neither characterized nor recognized for their multifaceted significance.

Conservation of birds in fragmented landscapes requires protected areas

For successful conservation of biodiversity, it is vital to know whether protected areas in increasingly fragmented landscapes effectively safeguard species. However, how large habitat fragments must be, and what level of protection is required to sustain species, remains poorly known. We compiled a global dataset on almost 2000 bird species in 741 forest fragments varying in size and protection status, and show that protection is associated with higher bird occurrence, especially for threatened species. Protection becomes increasingly effective with increasing size of forest fragments.
