Debate about what proportion of the Earth to protect often overshadows the question of how nature should be conserved and by whom. We present a systematic review and narrative synthesis of 169 publications investigating how different forms of governance influence conservation outcomes, paying particular attention to the role played by Indigenous peoples and local communities. We find a stark contrast between the outcomes produced by externally controlled conservation, and those produced by locally controlled efforts.

Using a spatially explicit framework with low/middle-income country coastal characteristics, we explore whether aspatial policies augment the impact of marine protected areas(MPAs)and identify when MPAs create income burdens on communities. When MPAs are small and budget-constrained, they cannot resolve all of the marinescape’s open-access issues, but they can create win-win opportunities for ecological and economic goals at lower levels of enforcement.

In this study we examine whether and why preferences for environmental quality improvements depend on current quality. We conducted contingent valuation surveys over the course of a year in Nanjing, China, and find that the willingness to pay for future air quality improvements increases by 0.693% for every 1% increase in the current PM2.5 level. Therefore, the issue of "when" a valuation study is conducted has important implications for the estimation of benefits, and further deserves consideration when applying benefit transfer methods.
