Drivers and Impacts of Tropical Deforestation

Tropical deforestation is driven by a complex interplay of agricultural expansion, commodity markets, infrastructure development, logging and demographic pressures. Rising global demand for food and biofuels has incentivised the conversion of forests into cropland and pasture, while improvements in road networks facilitate access to remote regions. Weak governance, land tenure insecurity and poverty further accelerate clearance, as local communities resort to forest exploitation for livelihood needs. The impacts of forest loss are profound: irreversible biodiversity decline; increased carbon emissions that exacerbate climate change; disruption of water cycles; soil erosion; and threats to ecosystem services on which millions depend. Effective mitigation requires integrated policies spanning supply-chain transparency, land-use planning, protected area management and support for sustainable rural development.

Research from Nature Portfolio

Recent studies have analysed deforestation through a food-system lens, demonstrating that trade- and demand-side factors such as foreign direct investment and urban population growth account for a large share of forest loss in tropical and subtropical regions. Machine-learning models explain up to 81% of deforestation variability in Asia and 73% in Latin America, but perform less well in Africa, signalling the need to address region-specific drivers beyond the food system. Foundational satellite-based analyses have also established a robust link between per-capita income growth and forest cover change, revealing that the strongest deforestation pressures occur at early stages of economic development and weaken as nations reach higher income thresholds, consistent with an environmental Kuznets curve for forests.

Drivers and Impacts of Tropical Deforestation publication trend

The graph below shows the total number of articles in drivers and impacts of tropical deforestation across all publications each year (not limited to Nature Index journals).

Technical terms

Deforestation: Permanent removal of forest cover for non-forest land uses such as agriculture or infrastructure.

Forest degradation: Decline in forest quality and ecosystem function due to selective logging, fire or fragmentation.

Agricultural expansion: Conversion of forest lands into cropland or pasture driven by rising food and commodity demand.

Commodity-driven deforestation: Forest loss primarily linked to production of export-oriented agricultural or timber commodities.

REDD+: Policy framework offering financial incentives to reduce emissions from deforestation and forest degradation.
