Study shows market-based strategies for ecosystem conservation are surging [Phys]

Programs in which people pay landholders to support natural systems that provide benefits like flood protection, biodiversity and carbon storage, are expanding around the world, according to a new UCLA-led study.
The paper, published today in Nature Sustainability, is the first peer-reviewed, global assessment of "payments for ecosystem services" mechanisms. Leading the study were James Salzman, Donald Bren Distinguished Professor of Environmental Law at UCLA School of Law and the Bren School of the Environment at UC Santa Barbara, and researchers at Ecosystem Marketplace, an initiative of the non-profit Forest Trends.
