Biodiversity and ecosystems provide many critical life support functions and benefits for human wellbeing, security and economic growth, including food, clean water, recreational services and climate regulation. Despite its significant values, biodiversity worldwide is being lost, in some areas at a rapid rate.
Given these losses, there is an urgent need for firstly, greater application of policies and incentives to promote the conservation and sustainable use of biodiversity and ecosystem services, and secondly, a more efficient use of available finance in existing biodiversity programmes. PES is a flexible, incentive-based mechanism that has potential to deliver in both of these areas. This Thematic Issue of Science for Environment Policy explores research which can help guide effective Payments for Ecosystem Services (PES) schemes. Under PES agreements, a user or beneficiary of an ecosystem service provides payments to individuals or communities whose management decisions and practices influence the provision of ecosystem services.
