Methane is a potent, short-lived climate pollutant responsible for nearly 0.5°C of global temperature rise. Though it remains in the atmosphere for about 12 years, its climate impact is 86 times stronger than carbon dioxide over 20 years, making methane mitigation one of the most effective strategies for tackling climate change. The waste sector...

Sunda clouded leopard conservation requires understanding key species traits. Using photo-identification, we estimated lifespans from minimum residence times, documenting the oldest wild individual known to date—a 6.51-year-old female. We discuss methodological limitations in female detectability and transient individuals in the population and...

Agriculture lies at the centre of the climate change challenge, simultaneously functioning as a highly climate-vulnerable sector and a significant contributor to greenhouse gas emissions through land use, crop production, livestock, and food systems. This presentation examines the climate change–agriculture nexus through a comparative analysis of...

Although masting in Southeast Asia is characterized by the interspecific synchronization of reproduction, little is known about the variation in regeneration strategies among sympatric tree species during major masting events. Herein, we examined the hypothesis that non-abundant species achieve greater seed survival per seed production at the pre-...

This summary report presents the results of the technical analysis of the third biennial update report of Malaysia, conducted by a team of technical experts in accordance with the modalities and procedures contained in the annex to decision 20/CP.19.

Rapid development in Bintulu has resulted in large-scale changes in land use, especially the conversion of forests into oil palm plantations and industrial tree plantations. Using high-resolution satellite imagery, we analysed land-cover types in the Kemena–Tubau–Lower Jelalong region of Sebauh subdistrict and classified them into nine major land...
