Global biodiversity finance : the case for international payments for ecosystem services
2014
Global spending on nature conservation is currently estimated at around US$50 billion per year. Most of this is public money, yet even this is far from sufficient to maintain biodiversity and the ecosystem services upon which our economies, livelihoods and well-being depend. For this reason, many governments are using payments for ecosystem services (PES) and related market-based instruments to encourage the private sector to do more to protect the environment.
