Tropical forests are rapidly disappearing. In the last 60 years, more than half of the tropical forests worldwide have been destroyed. The EU-funded FORESTPOLICY project will improve our understanding of the conditions under which supply chain policies can lead to better conservation and livelihoods in the tropics. Specifically, it examines whether company policies to stop sourcing products associated with deforestation have helped to slow forest clearing and encourage restoration. It then assesses whether environmental effectiveness comes at the cost of excluding poorer farmers or rather benefits local communities. Finally, it identifies why supply chain policies succeed or fail, examining the governance context in the production regions. The findings will support improved decision-making to help end deforestation.
