TL;DR: Assessment of three broad management strategies, plastic waste reduction, waste management, and environmental recovery, at different levels of effort to estimate plastic emissions to 2030 for 173 countries found that 19 to 23 million metric tons, or 11%, of plastic waste generated globally in 2016 entered aquatic ecosystems.
Journal ArticleDOI
Effectiveness of terrestrial protected areas in reducing habitat loss and population declines
Jonas Geldmann,Megan Barnes,Lauren Coad,Ian D. Craigie,Marc Hockings,Neil D. Burgess,Neil D. Burgess +6 more
TL;DR: Overall, available evidence suggests that PAs deliver positive outcomes, but there remains a limited evidence base, and weak understanding of the conditions under which PAs succeed or fail to deliver conservation outcomes.
Journal ArticleDOI
Capacity shortfalls hinder the performance of marine protected areas globally
David Gill,Michael B. Mascia,Gabby N. Ahmadia,Louise Glew,Sarah E. Lester,Megan Barnes,Ian D. Craigie,Emily S. Darling,Christopher M. Free,Jonas Geldmann,Susie Holst,Olaf P. Jensen,Alan T. White,Xavier Basurto,Lauren Coad,Ruth D. Gates,Greg Guannel,Peter J. Mumby,Hannah Thomas,Sarah Whitmee,Stephen Woodley,Helen E. Fox +21 more
TL;DR: It is reported that many MPAs failed to meet thresholds for effective and equitable management processes, with widespread shortfalls in staff and financial resources; continued global expansion of MPAs without adequate investment in human and financial capacity is likely to lead to sub-optimal conservation outcomes.
Journal ArticleDOI
Why do we map threats? Linking threat mapping with actions to make better conservation decisions
Vivitskaia J. D. Tulloch,Ayesha I. T. Tulloch,Ayesha I. T. Tulloch,Piero Visconti,Benjamin S. Halpern,Benjamin S. Halpern,James E. M. Watson,James E. M. Watson,Megan C. Evans,Nancy A. Auerbach,Megan Barnes,Maria Beger,Iadine Chadès,Sylvaine Giakoumi,Eve McDonald-Madden,Eve McDonald-Madden,Nicholas J. Murray,Nicholas J. Murray,Nicholas J. Murray,Jeremy Ringma,Hugh P. Possingham,Hugh P. Possingham +21 more
TL;DR: It is shown that threat mapping can be a useful tool when incorporated within a transparent and repeatable structured decision-making (SDM) process that ensures transparent and defendable conservation decisions by linking objectives to biodiversity outcomes, and by considering constraints, consequences of actions, and uncertainty.
Journal ArticleDOI
Changes in protected area management effectiveness over time: a global analysis
Jonas Geldmann,Lauren Coad,Lauren Coad,Megan Barnes,Ian D. Craigie,Marc Hockings,Marc Hockings,Kathryn Knights,Fiona Leverington,Ivon C. Cuadros,Camilo Zamora,Stephen Woodley,Neil D. Burgess,Neil D. Burgess +13 more
TL;DR: In this article, the authors present results on how management effectiveness scores change in protected areas receiving conservation investment, using a globally expanded database of protected area management effectiveness, focusing on the "management effectiveness tracking tool" (METT).
