This study demonstrates how different payment mechanisms can stimulate the efficient delivery of key, high-value ecosystem services that are either not produced, or are under-produced, by the normal operation of the market. Two payment mechanisms are considered: payments from the public sector to private businesses and payments between private businesses.
Public to private funding is the most common Payment for Ecosystem Services (PES) mechanism in most countries. By contrast, private to private PES mechanisms remain relatively novel, although they have great potential for incentivising environmental improvements, particularly in cases where there is a profit opportunity arising from such improvements. Permutations of these mechanisms are illustrated through three case studies: (1) Public to private funding of natural capital improvements at the national level, (2) Public to private funding of natural capital improvements at the catchment level, and (3) Business to business funding of natural capital improvements at a catchment level.
