Tropical forests provide a variety of ecosystem services that are also of great global relevance, such as climate regulation and the provision of habitat for animals and plants. However, climate change can impair these services, which also has serious economic consequences.

Tropical deforestation causes large reductions in observed precipitation

Tropical forests play a critical role in the hydrological cycle and can influence local and regional precipitation. Previous work has assessed the impacts of tropical deforestation on precipitation, but these efforts have been largely limited to case studies. A wider analysis of interactions between deforestation and precipitation— and especially how any such interactions might vary across spatial scales—is lacking. Here we show reduced precipitation over deforested regions across the tropics.

The Policy Implications of the Dasgupta Review: Land Use Change and Biodiversity

The “Dasgupta Review” of the economics of biodiversity (Dasgupta 2021) identifies many factors that threaten the ecological sustainability of our economies. This article examines how two policy failures - the underpricing and underfunding of nature – influence global land use change and terrestrial biodiversity loss. If natural areas are priced too cheaply, then converting them to agriculture, forestry and other land uses is less costly than protecting or preserving habitats. Underfunding nature further reduces the incentives for conservation and restoration.

Tropical forests as key sites of the “Anthropocene”: Past and present perspectives

Tropical forests are on the front line of climate change and human sustainability challenges, being key environments in discussions of the “Anthropocene” and some of the most threatened land-based habitats on the face of the Earth. However, while it has been acknowledged that 21st-century anthropogenic alterations to tropical forests have the potential to set off major earth systems feedbacks on regional to global scales, there has been less discussion on how past human activities may have had similar impacts.
