“…To date, efforts to manage natural resources in the Bay of Assassins have tended to focus on a single ecosystem or species, for example establishing closed seasons for octopus fisheries, introducing new techniques for sea cucumber aquaculture, and creating protected areas for mangrove forest where wood harvesting is forbidden (Andriamalala and Gardner 2010;Aina 2010;Benbow et al 2014;Cripps and Gardner 2016). The key resource management lesson is that livelihoods in coastal communities cut across terrestrial, wetland and aquatic ecosystems.…”

Informal small-scale mangrove wood harvesting has received limited attention, though it is a widespread threat to mangroves in many parts of the tropics. We investigated wood use and the impacts of harvesting on mangrove forests in the Bay of Assassins in southwest Madagascar. We measured forest structure, composition, and harvesting across 60 vegetation plots and investigated human uses of the mangroves through Rapid Rural Appraisal techniques. We found that unlike other mangroves in the region, those in the Bay of Assassins are dominated by Ceriops tagal. Tree harvesting rates are high, with a mean of 28.7% (SD 19.4) of trees harvested per plot. This is similar to heavily harvested mangroves in other parts of the tropics. A comparison of tree versus sapling importance of the different mangrove tree species indicates that the composition of the mangrove forest is changing, with C. tagal becoming more important. Livelihood activities drive the harvesting of certain species and size classes. Mangrove wood is used mainly for the construction of traditional housing and fencing. There are also emerging uses of mangrove wood, including seaweed (Kappaphycus alvarezii) aquaculture and the production of 'sokay', a lime render made by burning sea shells in mangrove wood kilns and used to improve the durability of houses. Small-scale selective harvesting of mangrove wood is important for local livelihoods but may have wide-ranging impacts on forest composition and structure. Demand for mangrove wood has grown in relation to new commodity chains for marine products, demonstrating the need for integrated landscape management that considers wetland, terrestrial and marine resources together.

“…For example, temporary reef octopus fishery closures in southwest Madagascar-established using Dina, that is, customary sociocultural laws-are heralded to have produced positive ecological outcomes and improved catches for local resource-dependent fisher households, which incentivize ongoing compliance (see Benbow et al, 2014;Harris, 2007). For example, temporary reef octopus fishery closures in southwest Madagascar-established using Dina, that is, customary sociocultural laws-are heralded to have produced positive ecological outcomes and improved catches for local resource-dependent fisher households, which incentivize ongoing compliance (see Benbow et al, 2014;Harris, 2007).…”

“…Customary and local institutions take many forms, including practices that protect temporarily or over the long-term specific biodiversity and ecosystems of value, and social norms that determine who has access to resources and what rules are in place to incentivize compliance. For example, temporary reef octopus fishery closures in southwest Madagascar-established using Dina, that is, customary sociocultural laws-are heralded to have produced positive ecological outcomes and improved catches for local resource-dependent fisher households, which incentivize ongoing compliance (see Benbow et al, 2014;Harris, 2007). Likewise, McClanahan, Muthiga, and Abunge (2016) have shown the potential of tengefu (i.e., community fishery closures) in Kenya for successful fisheries management, though these are not without some challenges.…”

Strategies to protect biodiversity in the face of a global crisis must be placebased and sensitive to context. A failure to consider the socioeconomic and political circumstances, as well as wellbeing needs and lived realities of those most directly reliant upon biodiversity will further undermine progress on Aichi targets and subsequent goals for the post-2020 framework. How communities experience the benefits or costs of conservation action is influenced in large measure by the principles that guide conservation governance, and the subsequent institutional structures and processes that frame conservation action (at local to global scales). In this article, we define and critically reflect on core principles of community-centered conservation governance needed to yield desirable and long-term conservation outcomes-both ecological and social (i.e., equitable and just). In doing so, we emphasize a conception of community-centered conservation that we argue is relevant to guide implementation of a post-2020 biodiversity framework, and which is based on a foundation of well-established evidence. Core principles of communitycentered conservation governance include: (a) building multilevel networks and collaborative relationships needed to coproduce conservation solutions;(b) promoting equity and recognizing the central role of women as agents of positive change in conservation efforts across scales; (c) reframing conservation action through the lens of reconciliation and redress (e.g., responding to injustices from land grabs and territorial enclosures); (d) ensuring a rightsbased approach to conservation action in which community agency, access and decision making autonomy are supported; and (e) revitalizing the customary and local institutions that provide legitimate and adaptive strategies for the stewardship of biodiversity.

“…In coastal southwest Madagascar today, settlement mobility is constrained by conservation and development initiatives that seek to regulate resource use within recently established zones managed by spatially fixed associations of local communities (57). Although positive outcomes have emerged from these efforts, such as increased catch of commercially valuable taxa (58), tensions have also arisen as zone-based management approaches conflict with established migratory practices (59) (Fig. 4B).…”

Climate change impacts island communities all over the world. Sea-level rise, an increase in the frequency and intensity of severe weather events, and changes in distribution and health of marine organisms are among the most significant processes affecting island communities worldwide. On islands of the Caribbean and southwestern Indian Ocean (SWIO), however, today’s climate change impacts are magnified by historical environmental injustice and colonial legacies, which have heightened the vulnerability of human and other biotic communities. For some islands, archaeological and paleoecological research offers an important record of precolonial climate change and its interplay with human lives and landscapes. The archaeological record suggests strategies and mechanisms that can inform discussions of resilience in the face of climate change. We detail climate-related challenges facing island Caribbean and SWIO communities using archaeological and paleoecological evidence for past climate change and human response and argue that these cannot be successfully addressed without an understanding of the processes that have, over time, disrupted livelihoods, reshaped land- and seascapes, threatened intergenerational ecological knowledge transfer, and led to increased inequality and climate vulnerability.
