    Protected areas (PAs) are our principal conservation strategy and are evolving rapidly, but we know little about the real-world management and governance of new forms. We review the evolution of Madagascar’s PA system from 2003-2016 based on our experience as practitioners involved. During this period PA coverage quadrupled and the network of strict, centrally-governed protected areas expanded to include sites characterized by: i) multiple-use management models in which sustainable extractive natural resource uses are permitted, ii) shared governance arrangements involving non-governmental organizations (NGOs) and local community associations, and iii) a management emphasis on livelihood-based approaches and social safeguards. We discuss the principal challenges for the effectiveness of the expanded system and detail management/policy responses. These include i) enhancing stakeholder participation, ii) ensuring financial sustainability, iii) enforcing rules, iv) ensuring the ecological sustainability of PAs faced with permitted resource extraction, v) reducing the natural resource dependence of local communities through transformative livelihood change, and vi) developing long-term visions to reconcile the differing objectives of conservation NGOs and other stakeholders. In general PAs have had limited effectiveness in reducing deforestation and other threats, which may be related to their rapid establishment processes and the complexity of management towards multiple objectives, coupled with insufficient resources. While Madagascar’s achievements provide a basis for conserving the country’s biodiversity, the challenge faced by its protected areas will continue to grow

    Madagascar’s extraordinary biodiversity: Evolution, distribution, and use

    Madagascar's biota is hyperdiverse and includes exceptional levels of endemicity. We review the current state of knowledge on Madagascar's past and current terrestrial and freshwater biodiversity by compiling and presenting comprehensive data on species diversity, endemism, and rates of species description and human uses, in addition to presenting an updated and simplified map of vegetation types. We report a substantial increase of records and species new to science in recent years; however, the diversity and evolution of many groups remain practically unknown (e.g., fungi and most invertebrates). Digitization efforts are increasing the resolution of species richness patterns and we highlight the crucial role of field- and collections-based research for advancing biodiversity knowledge and identifying gaps in our understanding, particularly as species richness corresponds closely to collection effort. Phylogenetic diversity patterns mirror that of species richness and endemism in most of the analyzed groups. We highlight humid forests as centers of diversity and endemism because of their role as refugia and centers of recent and rapid radiations. However, the distinct endemism of other areas, such as the grassland-woodland mosaic of the Central Highlands and the spiny forest of the southwest, is also biologically important despite lower species richness. The documented uses of Malagasy biodiversity are manifold, with much potential for the uncovering of new useful traits for food, medicine, and climate mitigation. The data presented here showcase Madagascar as a unique living laboratory for our understanding of evolution and the complex interactions between people and nature. The gathering and analysis of biodiversity data must continue and accelerate if we are to fully understand and safeguard this unique subset of Earth's biodiversity

    Madagascar’s extraordinary biodiversity: Threats and opportunities

    Madagascar's unique biota is heavily affected by human activity and is under intense threat. Here, we review the current state of knowledge on the conservation status of Madagascar's terrestrial and freshwater biodiversity by presenting data and analyses on documented and predicted species-level conservation statuses, the most prevalent and relevant threats, ex situ collections and programs, and the coverage and comprehensiveness of protected areas. The existing terrestrial protected area network in Madagascar covers 10.4% of its land area and includes at least part of the range of the majority of described native species of vertebrates with known distributions (97.1% of freshwater fishes, amphibians, reptiles, birds, and mammals combined) and plants (67.7%). The overall figures are higher for threatened species (97.7% of threatened vertebrates and 79.6% of threatened plants occurring within at least one protected area). International Union for Conservation of Nature (IUCN) Red List assessments and Bayesian neural network analyses for plants identify overexploitation of biological resources and unsustainable agriculture as themost prominent threats to biodiversity. We highlight five opportunities for action at multiple levels to ensure that conservation and ecological restoration objectives, programs, and activities take account of complex underlying and interacting factors and produce tangible benefits for the biodiversity and people of Madagascar

    Madagascar: Crime threatens biodiversity

    [Extract] Madagascar's new president, Andry Rajoelina, was elected on a promise to improve living standards for the millions who live in poverty. To achieve this goal, he must address the declining rule of law. Madagascar fell eight places in the Rule of Law Index between 2016 and 2018, and it is 155th of 180 countries listed in the Corruption Perceptions Index. Weak governance slows development by reducing the willingness of citizens and foreign companies to invest. Since his election, President Rajoelina has expressed a desire to make Madagascar a model of conservation and a destina-tion for ecotourism

    Last chance for Madagascar’s biodiversity

    Madagascar’s recently elected president ran on a platform of improving the economy and raising people out of poverty. We suggest that addressing the precipitous decline of biodiversity will help to deliver this commitment, and we lay out ways in which President Rajoelina could firmly put the country on a trajectory towards sustainable growth
