    Smallholder Zebu and Forage Production Development in Central Madagascar

    Poverty in the Central Highlands of Madagascar is partly driven by inefficient exploitation of native forages and poor livestock nutrition. Zebus are of importance as cultural symbols, but this tradition has grown disconnected from agricultural policy. This project is working with three central highland communities near the protected areas of Itremo, Ibity and Ankafobe, to boost rangeland productivity and trial management methods which will support key forage grasses and improve livestock nutrition. A severe nitrogen deficiency compounded by extremely acidic soil conditions and low phosphorus is observed across the three sites. The lowest grazing capacity of an estimated 0.7 livestock unit per hectare and biomass production of 1600 kg/ha is observed at Ankafobe, the highest elevation windy site with fires that are almost annual. Low production is due to acidic soils with a lack of phosphorus as well as likely iron toxicity. The project works with 90 households owning a total 150 female zebu, 1-5 per household. The project initiated 3 demonstration farms to show the planting of sorghum for silage, harvesting of the native grasses for hay, and building a secure barn meeting at least minimum animal care standards, using local materials to protect the livestock from the weather and theft which is sadly perceived to be common. In the first year the project produced the highest yields in the most remote and fertile site of Itremo, with 365 kg of sorghum silage from 0.5 ha and 165 kg of Brachiaria hay from 0.5 ha. Five households based in the milk producing region of eastern Ibity have completed new barns. Fifty percent of households at Ibity successfully fed silage and hay to their zebu for the first time. Madagascar remains famous for subsistence farming and rural poverty with a long-term decline in livestock, but substantial opportunity nevertheless exists for integrated crop and livestock production, alongside the protection of biodiversity in nearby forests

    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’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

    Achieving sustainable conservation in Madagascar : the case of the newly established Ibity Mountain Protected Area

    Globally, the number of protected areas (PAs) has increased exponentially during the last 25 years, particularly in biodiversity-rich developing countries. Many recent initiatives have integrated local-scale socio-economic development into both design and management. Because the rates of deforestation and species extinction are increasing in most parts of the world, substantial efforts have been made to build and strengthen local environmental organizations, to establish new protected areas (NPAs), and to improve natural resource management. An NPA was recently established at Ibity Massif in central Madagascar, where a community-based conservation project is being coordinated by the Missouri Botanical Garden (MBG). In December 2008, a temporary protection order was issued, and definitive establishment of the NPA, which falls under Category V of the IUCN PA system, is expected before the end of 2015. This initiative has involved significant outreach and community education programs to raise awareness of Ibity's conservation and economic importance and the threats to its biodiversity, along with ongoing efforts to reduce fire frequency and implement ecological restoration projects with significant local community participation. In order to ensure the sustainability of this NPA, a co-management plan has been implemented involving MBG, local authorities, and the local population. This study describes the diagnostic process undertaken at Ibity in order to: 1) disseminate the data gathered to inform establishment of the NPA; and 2) summarize the initial state of the environment on the massif prior to the implementation of a management plan, as a baseline for assessing the NPA's effectiveness
