Interviews with pastoralists from 26 villages are analyzed within a framework of contemporary new institutional economics to investigate pastoral mobility, as a response to the Madagascar-wide problem of cattle raiders ( dahalo ). The conditions for the new movement are compared to a traditional transhumance movement comprising the same actors but in reverse geographical direction. Contrary to many previous studies from Madagascar, the results reveal that property rights regarding access to ancestral land are not a constraint to pastoral mobility. The new transhumance movement was enabled by pro-social norms of solidarity, guest rights and unconditional hospitality ( fihavanana ) shared by the pastoralists in the region. Additional vital elements are mental models of kinship  (raza, longo ) and the formal indigenous institution of trust creation by sincerity oaths ( titike, kine ). However, frequent cattle raids have led to social change and an environment of mistrust; placing social constraints on pastoral mobility. Hospitality and guest rights are increasingly bound to kinship relations, and the pastoralists’ interpretation of kinship has become narrower. These social constraints are far more relevant to the new movement than to the more institutionalized traditional transhumance. The findings illustrate how Madagascar’s cattle raiding problem has influenced the rural society’s social norms and mental models. The study highlights how supportive social norms and fitting shared mental models influence people’s capacity to adapt, especially in sociocultural settings ruled by informal indigenous institutions.","PeriodicalId":89438,"journal":{"name":"Madagascar conservation and development","volume":"11 1","pages":"12-22"},"PeriodicalIF":0.0,"publicationDate":"2016-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4314/MCD.V11I1.3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70562904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The degraded secondary forest remnant of Analalava, on the east coast, near Foulpointe, is a protected area since 2006. The long-term conservation of the site’s biodiversity can only be guaranteed by local support. Given that access to timber from native trees within the protected area is restricted, management of tree resources outside of the protected area represents a critical nexus between biodiversity conservation and human benefits linked to ecosystem services. We investigated and characterized the local farmer's use of available tree species, to provide a basis for satisfying the dual objectives of biodiversity conservation and sustainable and equitable rural development. Our results showed that local people are interested in various types of trees for timber, both native and introduced. Furthermore, they demonstrated detailed knowledge about silvicultural traits of a large number of tree species. Regarding the important complementarity of properties and uses recognized for native and introduced species we conclude that free distribution of nursery seedlings of fast-growing introduced tree species should not be the only alternative to logging within the protected forest fragment offered to local people. Instead, a larger choice of tree species, including native ones, should be proposed. The cultivation of this diverse mix would allow people to take a more active part in the preservation and restoration of natural capital at the landscape scale and could enlarge the range of benefits obtained from trees that they plant.

The current study collected socioeconomic data from the Alaotra wetland stakeholders within three locations around Lake Alaotra to contextualize local livelihoods and to identify the drivers and barriers for the utilization of this plant. Methods of control seem to be unrealistic due to institutional and financial limitations in Madagascar. Using the plant as fertilizer, animal fodder or for handicrafts seems to represent a feasible alternative to improve the livelihood of the local population.

As the size of many remaining forest fragments is unlikely to maintain viable animal populations in the long-term, connecting isolated subpopulations by creating corridors is important to support gene flow and the persistence of the endemic fauna, including lemurs. Since restoration with endemic trees is slow, exotic trees may represent a faster alternative to initiate habitats that can be used by animals. Here, we studied whether or not grey mouse lemurs, Microcebus murinus , use corridors composed of exotic and native trees of different age and composition to move between littoral forest fragments. For this, we trapped M. murinus in four forest fragments and mixed tree plantations between the fragments. One of the corridors was composed of a mixture of endemic and mature exotic Eucalyptus robusta trees. The second corridor consisted mainly of an old stand of exotic Melaleuca quinquenervia . The third corridor was composed of exotic Acacia mangium trees planted in 2009. During four years of study, only one male M.murinus used the Melaleuca corridor, while several M. murinus were caught in the Eucalyptus and the Acacia corridor in 2013. The density of the corridor under-story appeared to influence the number of individuals captured; the corridor with highest understory density was used most. The captures within the corridors illustrate that exotic trees allow movements of mouse lemurs within less than 5 years after plantation.","PeriodicalId":89438,"journal":{"name":"Madagascar conservation and development","volume":"10 1","pages":"144-150"},"PeriodicalIF":0.0,"publicationDate":"2015-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4314/MCD.V10I3.7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70562850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A study was conducted on the importance of this species in handcrafts and the ecological impacts in three Fokontany around the Baie de Rigny. Ethnobotanical surveys were conducted with women aged between 14 and 70 years old who commonly created baskets, from the collection of leaves until the sale of the finished products. The evaluation of human activities on the production of H. coriacea leaves was conducted by counting leaves produced by 175 palm trees subjected to different sampling conditions during one year. On average, one person collects 120 to 160 leaves, produces 60 to 80 baskets and earns 43,200 Ariary per month. The collection of the leaves contributes to sustainable management by using special tools and practices during collection such as not completely cutting down palms. However, collection of leaves negatively impacts production of leaves by reducing their number. Rotating leaf collection, restricting the number of leaves collected on each individual per year, and protection of the vegetation against brush fires are strongly advised while respecting the management techniques already in use.

In  Madagascar, forest resources make important contributions to the livelihoods of the rural population  living at the edges of these forests. Although people benefit from forest resources, forests are  continuously cleared and converted into arable land. Despite long-term efforts on the part of researchers, development cooperation projects and government, Madagascar has not been able to achieve a  fundamental decrease in deforestation. The question of why deforestation continues in spite of such efforts remains. To answer this question, we aimed at understanding deforestation and forest fragmentation from the perspective of rural households in the Manompana corridor on the east coast. Applying a  sustainable livelihood approach, we explored local social-ecological systems to understand: (i) how  livelihood strategies leading to deforestation evolve and (ii) how the decrease of forest impacts on  households' strategies. Results highlight the complexity of the environmental, cultural and political context in which households’ decision-making takes place. Further, we found crucial impacts of  deforestation and forest fragmentation on livelihood systems, but also recognized that people have been able to adapt to the changing landscapes without major impacts on their welfare. Partout dans le monde les forets fournissent une grande variete de ressources aux habitants des regions  rurales, particulierement aux plus pauvres. A Madagascar, les ressources forestieres contribuent dans une grande mesure aux moyens d’existence des populations riveraines des forets. Cependant, bien que les populations tirent parti des ressources de la foret, les defrichements ne cessent pas et la conversion des zones boisees en terres cultivables se poursuit. Malgre les efforts entrepris depuis des annees par les milieux de la recherche et du developpement ainsi que par le gouvernement, Madagascar n’a pas encore connu d’inversion du rythme de la deforestation. Pourquoi les defrichements se poursuivent-ils en depit des efforts entrepris ? C’est a cette question que nous souhaitons apporter une reponse en essayant de comprendre la deforestation et la fragmentation des forets en prenant en compte les moyens d’existence des menages ruraux dans le corridor de Manompana, cote Est de Madagascar.
