TLDR
In this article, the authors used statistical matching to conduct a rigorous impact evaluation of dual management systems on coral reef fishes in Tonga, with communities having both full no-take areas and areas of exclusive fishing rights.Abstract:
Combining no-take marine reserves with exclusive access by communities to unreserved waters could provide the required incentives for community management to achieve positive impacts. However, few protected areas have been critically evaluated for their impact, which involves applying counterfactual thinking to predict conditions within protected areas if management had never occurred. Here, we use statistical matching to conduct a rigorous impact evaluation of dual management systems on coral reef fishes in Tonga, with communities having both full no-take areas and areas of exclusive fishing rights. No-take areas generally had positive impacts on the species richness, biomass, density, and size of target reef fish, while exclusive access areas were similar to predicted counterfactual conditions. The latter is likely because overall fishing pressure in exclusive access areas might not actually change, although more fish could be exploited by communities with access rights. Our findings suggest that dual management is effective at incentivizing effective community-based no-take areas for biodiversity conservation and resource management.read more

TL;DR: In this paper , the authors examine three case studies of partially protected coral reef fishery systems to evaluate benefits and risks of their use as a management tool, and demonstrate three vignettes of how partial protection can boost fisheries production, enhance the ease with which fishers catch their prey, and alter the composition of fisheries yields.

Why does conservation minimize opportunity costs?
TL;DR: The relationship between opportunity costs and conservation impact is explored in this article , where the authors argue that if conservationists make choices to minimize opportunity costs, they are also necessarily limiting their impact.

TL;DR: The results show that global conservation targets based on area alone will not optimize protection of marine biodiversity, and more emphasis is needed on better MPA design, durable management and compliance to ensure that MPAs achieve their desired conservation value.
