“…The latest phase of government environmental policies, initiated with the 'Durban vision' of President Ravalomanana in 2003, aimed to triple the area of protected zones (Corson 2014). However, the success of conservation projects has been mixed at best, and deforestation still has not been stopped (Sayer 2009;Freudenberger 2010;Brinkmann et al 2014;Corson 2014;Zinner et al 2014).…”

“…On the other hand, Madagascar ranks 155th of 187 states in the Human Development Index and serves as a prime example of a region in which a large share of the population depends heavily on the ecosystem services provided by their environment for survival and in which the risk of malnutrition is very high (Scales 2014a;UNDP 2014;Welthungerhilfe 2014). Despite efforts by GOs and NGOs to conserve forests and improve the situation of the rural population, deforestation in Madagascar is proceeding at rates close to 1% per year, with regional highs above 2% per year (Harper et al 2007;ONE et al 2013;Brinkmann et al 2014;Zinner et al 2014). The situation in Madagascar is thus exemplary of many biodiversity-rich developing countries striving to reconcile development and conservation objectives.…”

Global benefits and local costs – The dilemma of tropical forest conservation: A review of the situation in Madagascar

2016

SUMMARYDeforestation is one of the most important conservation problems in tropical developing countries, even though cost-benefit analyses consistently show that forest conservation is economically beneficial. In Madagascar, deforestation continues at alarming rates despite numerous initiatives of international donors to increase incentives for local households to support forest conservation. In this literature review, we contrast cost-benefit analyses for forest conservation with: (1) the actual burdens and (2) the actual gains of forest conservation for rural households, generated mainly in the context of conservation projects. We show that approaches to generating direct benefits deliver less value than expected for rural communities; the benefit transfer mechanisms are insufficient as the majority of benefits are captured by other stakeholders, and increased benefit transfer is limited by structural and institutional limitations in local communities, valuation chains and in terms of governance failure at higher levels.

“…Most of this biodiversity is conserved within the Tsimanampetsotsa National Park (Ministère de l'Environnement et Association Nationale pour la Gestion des Aires Protégées 1999) and remaining small patches of sacred forests (Tengö et al 2007). In other parts of the region, a rapidly growing human population, with an annual increase of 3 % within the last 20 years and 3.5 % within the last 5 years (INSTAT 2014), and a rising tendency for 'clandestine pioneer-agriculture' enhances the pressure on natural resources (Brinkmann et al 2014).…”

For the purpose of this study, similar land use categories, such as dry spiny forest thicket and open spiny forest, were merged into one category (here: spiny forest and thicket), and one additional class, settlement area, was defined.…”

In order to investigate spatial and temporal characteristics of the purely grazing-based livestock husbandry system in southwestern Madagascar, individual animals from 12 cattle and 12 goat herds that were equally distributed across four villages were fitted with GPS tracking collars and their behaviour during pasturing was directly observed to identify seasonal variations in land use and movement patterns along the regional altitude and vegetation gradient. Monitoring occurred at regular intervals of two months over a two-year period to capture inter-annual variability. Herds of both species from the inland limestone plateau covered longer distances and were found further away from their home corrals than those from the coastal plain. Patterns of feeding behaviour and utilization of grazing areas mostly reflected the spatial occurrence of specific land cover classes around the villages and differed significantly between seasons and sites. Seasonal water shortage was one of the key factors affecting dry season livestock movements on the plateau but played a minor role in the coastal plain where livestock keeping proved to be more limited by feed availability. While on transhumance, mobile cattle herds were vulnerable to disadvantages such as limited access to pastureland and water sources nearby their temporary homesteads. The recent problem of armed cattle raids along with emerging land use conflicts compel livestock owners to utilize fewer grazing areas, which threatens to destabilize the region's animal husbandry system.

Trends in forest fragment research in Madagascar: Documented responses by lemurs and other taxa

The rise in research investigating fragmentation and its impact on primates and other taxa reflects the growing presence of fragmented landscapes themselves. Although numerous studies report the negative effects of fragmentation on biodiversity, it is difficult to generalize responses to fragmentation for specific taxonomic groups, such as non-human primates, when studies have not employed a definitive concept of fragmentation or fragments themselves. Madagascar's high degree of fragmentation, wealth of endemic taxa, and extensive history of ecological research provide the opportunity to compare fragmentation studies across similar contexts. We conducted a literature search of peer-reviewed articles on fragmentation in Madagascar to characterize its trends. A total of 70 articles, 46 of which concentrated on lemurs, tested the impacts of fragmentation on Malagasy taxa, while additional sources conducted research in one or more fragments without testing its effects (n = 112 total, 79 on lemurs). Studies on lemurs most frequently tested fragmentation's impacts on genetics and biodiversity metrics (n = 16 and 15 studies, respectively), although health, modeling, behavioral, and cross-disciplinary techniques were also reported. Responses to fragmentation were reported for 49 lemur species, with most studies concentrated in eastern Madagascar (87%). Although there was variation in the metrics reported in studies testing the effects of fragmentation on Malagasy species, the most common measures were fragment area, isolation, or comparison to a control site. Landscape-scale approaches and examination of fragmentation per se were rarely employed. Characterizing trends of fragmentation research in Madagascar emphasizes the challenges of documenting fragmentation's effects while highlighting the benefits of research within fragmented landscapes, particularly when combined with consideration for how the matrix within human-modified landscapes may impact primate populations.
