Timber harvest from tropical regions generates seven billion dollars annually in exports and is estimated to occur across 20% of the area of remaining tropical forests. This timber harvesting is estimated to account for more than one in eight of all greenhouse gas emissions from tropical forests. Yet there is currently no means to independently estimate extracted volumes and associated greenhouse gas emissions.

Tropical rainforests play a critical role in regulating the global climate system—they represent the Earth's largest terrestrial CO2 sink.

The FAO is the lead United Nations agency on the sustainable use of forests, and the voluntary guidelines refer to so-called forest concessions; laws and policies that allow local communities and p

Precise descriptions of forest productivity, biomass, and structure are essential for understanding ecosystem responses to climatic and anthropogenic changes. However, relations between these components are complex, in particular for tropical forests. We developed an approach to simulate carbon dynamics in the Amazon rainforest including around 410 billion individual trees within 7.8 million km.

Understanding how anthropogenic CO2 emissions will influence future precipitation is critical for sustainably managing ecosystems, particularly for drought-sensitive tropical forests. Although tropical precipitation change remains uncertain, nearly all models from the Coupled Model Intercomparison Project Phase 5 predict a strengthening zonal precipitation asymmetry by 2100, with relative increases over Asian and African tropical forests and decreases over South American forests.

The present study documents the wood-boring trace fossil Asthenopodichnium from the Palaeocene sediments of the Barmer Hill Formation (BHF) in the Barmer Basin, Western Rajasthan, India. The Asthenopodichnium trace fossils are loosely to tightly packed, pouch-like burrows or almond-shaped structures identified as Asthenopodichnium lignorum, whereas lozenge and J-shaped structures are designated as Asthenopodichnium lithuanicum.

Deforestation of the Amazon is about to reach a threshold beyond which the region's tropical rainforest may undergo irreversible changes that transform the landscape into degraded savanna with spar

Most of the world’s remaining tropical forests lie in areas that are customarily managed and/or legally owned by Indigenous Peoples and local communities.

Recently published research in the journal Environmental Research Letters found that setting a price of $20 per metric ton (about $18/short ton) of carbon dioxide could diminish deforestation b

Tropical forests all over the world are at risk from climate change and deforestation for arable land.
