  • Building Bridges in Biosphere Reserves –
    Building Bridges in Biosphere Reserves – The role of natural and social values in integrative conservation and development concepts in Madagascar Mananara-Nord and Sahamalaza Iles-Radama Biosphere Reserves I n a u g u r a l d i s s e r t a t i o n zur Erlangung des akademischen Grades doctor rerum naturalium (Dr. rer. nat.) an der Mathematisch-Naturwissenschaftlichen Fakultät der Ernst-Moritz-Arndt-Universität Greifswald vorgelegt von Nadine V. M. Fritz-Vietta geboren am 05.10.1979 in Darmstadt Greifswald, 23.12.2011 Dekan: Prof. Dr. Klaus Fesser 1. Gutachter: Prof. Dr. Susanne Stoll-Kleemann 2. Gutachter: Prof. Dr. Tim O‘Riordan Tag der Promotion: 22.05.2012 Valuing and knowing are not separate. How we know nature and how we value, or discount, nature are tightly linked. (Norgaard, 2009: 44) To my family Abstract Abstract The dissertation aims at developing means to integrate conservation and development in biosphere reserves in Madagascar. Despite a multitude of concepts such as UNESCO biosphere reserves, Integrated Conservation and Development Projects and community- based natural resource management, gaps between conservation and development remain to exist. In a qualitative case study in Mananara-Nord and Sahamalaza Biosphere Reserves in Madagascar data was collected on biosphere reserve management, local natural resource use, socio-cultural aspects and natural values local people associate with the forest. Analysis revealed that management capacities constitute a limiting factor in biosphere reserve management. Collaboration between management, local people and international organisations fosters the achievement of both conservation and development. However, collaboration only performs if a shared vision is established.

  • Repoblikan'ny Madagasikara
    IOTC-2018-WPDCS14-13 REPOBLIKAN’NY MADAGASIKARA FITIAVANA-TANINDRAZANA-FANDROSOANA ____________________________ MINISTERE DES RESSOURCES HALIEUTIQUES ET DE LA PECHE UNITE STATISTIQUE THONIERE D’ANTSIRANANA (USTA) 14TH WORKING PARTY ON DATA COLLECTION AND STATISTICS Victoria-Seychelles, 29th November to 1st December 2018 Gaillord JAONA Yacinthe RAZAFIMANDIMBY ABSTRACT In the framework to improve the fishery statistics in Madagascar, the Ministry of Fisheries, through the Unité Statistique Thonière d’Antsiranana, initiated in 2015 a monitoring system for small-scale and artisanal fisheries of pelagic fish in northern Madagascar with two pilot villages. Since 2016, Monitoring has been expanded in other villages where network of investigators have been established in the various potential fishing areas. At each catch landings, an investigator collects tuna catch data and other catches, and also performs sampling. The date of landing, the time at sea, fishing zone, the weight and total number of individuals landed are recorded; and measurements of tuna and tuna like species are conducted. According to the catch monitoring since the pilot phase in 2015, it can be seen that the tuna season in the northern waters of Madagascar is from June to October. In 2016, catches from small-scale fisheries in these two pilot villages reached 102 tons, including 59 tons of tuna and 43 tons of other catches. The tuna average catch is estimated at 5.3 tons per month. In 2017, total catches in the North of Madagascar reached 3 704 tons including 80 tons of tuna and 4 tons of swordfish from 192 692 landings. Indeed, tuna represents only 2% of total catch for these villages because small-scale and artisanal fishermen still face a challenge, which is the lack of appropriate equipment for catching tuna and tuna like species.

Population resides primarily in thirteen towns of the districts Antalaha, Maroantsetra, and Mananara. (Figure 1). Antongil Bay embodies the challenge of balancing conservation and development priorities. The Bay supports spectacular coral reefs, 13 marine mammal species, 3 marine turtle species, and 140 fish species (including 19 shark species). The Endangered scalloped hammerhead (Sphyrna lewini), the Endangered green turtles (Chelonia mydas) and the Critically Endangered hawksbill turtles (Eretmochelys imbricate) are threatened by small scale fishery by-catch and direct hunting.
