Tropical forests enhance regional rainfall but a robust analysis of this benefit is lacking. Consequently, the rainfall generating services of tropical forests are rarely accounted for in policymaking. We synthesised observational and model-based values of the reduction in rainfall due to tropical deforestation to quantify rainfall generation. Across these studies, we estimate that each meter squared of forest contributes 240 ± 60 L each year to regional rainfall. The Amazon forest has an even stronger rainfall benefit, with each meter squared of forest contributing 300 ± 110 L each year.

For decades, a dominant argument for protecting forests has focused on carbon. Trees absorb carbon dioxide, store it in wood and soils, and slow the accumulation of greenhouse gases. A new scientific review suggests this emphasis overlooks other ways forests shape climate and human well-being. Forests, it argues, are not only a mitigation tool for the future climate. They also help people adapt to climate change today, shaping temperature, water and human well-being in ways that are felt locally.

Meeting the ambitious targets set by the Convention on Biological Diversity (CBD) Kunming-Montreal Global Biodiversity Framework (GBF) will require expanding ecosystem restoration across governance domains for marine and coastal ecosystems. Marine spatial planning (MSP), which balances the development of multiple human uses in the ocean with the preservation of ecosystem health, might be the most effective vehicle for achieving this aim. However, to date, MSP and restoration efforts have proceeded on separate tracks, and biodiversity loss continues.

Since 2023, the Palau International Coral Reef Center (PICRC) has been collaborating with the Koror State Government (KSG) to conduct research and monitoring aimed at providing essential baseline data to guide the Koror Southern Lagoon Coastal Fisheries Management Plan, a new fisheries management initiative for Koror State. The management plan identified several fish spawning aggregation sites for protection, including the longnose emperor (melangmud, Lethrinus olivaceus) at Mutiaur.

Mangroves are trees and shrubs that grow in saline and brackish tidal waters across tropical and subtropical regions of the world.1Mangroves support rich biodiversity spanning both marine and terrestrial environments. Their roots anchor to the sediment, providing shelter for an array of marine fauna including fish, invertebrates, and mammals. Their canopy provides habitat, food, and shelter for many terrestrial organisms, including mammals such as tigers and monkeys, birds, reptiles, and insects.

Other Effective Area-based Conservation Measures (OECMs), introduced by the Convention on Biological Diversity (CBD), refer to areas outside formal protected-area networks that deliver effective and enduring in situ biodiversity conservation. This scoping review systematically examined global approaches to identifying and evaluating potential OECMs. Analysing 99 studies covering 694 case studies and 237 000 potential sites, we found that potential OECMs are widespread, particularly in Asia and terrestrial environments, with most initiatives led by the environmental sector.

Nurturing people-nature relationships in evolving social-ecological landscapes can slow biodiversity loss and build resilient communities
Biodiversity loss is often framed as a failure of conservation. In reality, it is a failure of relationships.

The loss of biodiversity is accelerating globally, and there is growing recognition that both halting and reversing this loss requires action from all of society, in addition to governments, civil society organisations, Indigenous peoples, local communities and the private sector.

Many islands are remote and the level of interest in land snails as a component of the global biodiversity conservation agenda is low. The conservation status of many island land snail faunas thus remains at best out of date. However, land snails have an asset that other groups do not—their shells, which can remain post mortem in the shell bank of the soil for many tens or several hundreds of years after the death of the animal.
