For the 100th episode of the Newscast, we revisit Mongabay's groundbreaking Conservation Effectiveness series which asked a simple question:

How can we know if conservation methods are working if we don't test their effectiveness? From marine protected areas to parks and certification schemes like 'green' labels on lumber, our team reviewed published studies and evaluated the evidence for each method. On this episode we speak with Mongabay's founder and editor-in-chief Rhett Butler about the Conservation Effectiveness series & the ongoing need to test conservation outcomes, and with Sven Wunder, a principal scientist at the European Forest Institute in Barcelona, who is also a senior associate at the Center for International Forestry Research (CIFOR), about the effectiveness of several of these conservation methods, like "payments for ecosystem services."
