Previous research identified three reasons for valuing nature (i.e., the basis for seeing nature as valuable and important): (1) valuing nature for what it gives to humans (instrumental), (2) valuing nature for its own sake (intrinsic), and (3) valuing nature because of the relationship between people and nature (relational). Of these, relational...

The Federated States of Micronesia (FSM) has launched its first Methane Reduction Roadmap, reinforcing its leadership as a Global Methane Pledge Champion. Methane is a potent short-lived climate pollutant, more than 80 times more powerful than carbon dioxide over a 20-year period. Reducing methane emissions offers rapid climate benefits, improved...

The International Union for Conservation of Nature (IUCN) is the world’s largest environmental network to advance nature conservation and sustainable development, with members including governments, civil society, Indigenous Peoples’ organizations, scientists, and businesses. Every four years, IUCN convenes its World Conservation Congress (WCC), a...

National‐scale monitoring of mangrove forests, including their spatial structure (e.g., canopy height and above‐ground biomass), is necessary for the implementation of global agreements related to climate change and biodiversity conservation. Field measurements of mangrove structural parameters, however, are costly to collect. Here, we investigated...
