Physical Environment and Human Context at Merapi Volcano: A Complex Balance Between Accessing Livelihoods and Coping with Volcanic Hazards

International audienceMerapi is a two-sided, paradoxical volcano: on the one hand 1.8 million people live on its flanks. It is one of the most densely populated volcanoes on Earth, with population densities averaging 764 inhabitants per square kilometre within a 10 km radius from the summit. The main reasons for the high densities are land resources and associated livelihoods from agriculture, livestock, sand mining, and tourism. On the other hand, Merapi is also one of the world’s most active volcanoes. Dome-collapse pyroclastic density currents (PDCs) occur every few years (e.g. 1994, 2002, 2006), and more violent explosive episodes are generated with an average recurrence interval of several decades (e.g. 1872, 1930, 2010). Risk management at Merapi is based on volcanic hazard zonation (called KRB I, II, and III, from the less exposed to the most exposed), derived from its eruptive history. Since its first publication by the Volcanological Survey of Indonesia in 1978, the danger map has been updated twice, in 2002 and after the deadly eruption of Merapi in 2010. Most of the information is provided by scientists during the ‘raising awareness program’ phase and achieved in the framework of a Community-Based Disaster Risk Management (CBDRM), which empowers communities with self-developed ways of coping with crises due to natural hazards. In periods of emergency, the Center for Volcanology and Geological Hazard Mitigation provides four warning levels of volcanic activity. In 2010, Merapi produced its largest eruption since 1872, damaging around 12,000 buildings, claiming 367 lives, including 200 directly by PDCs, and triggering massive evacuations of up to 400,000 people, as counted in the evacuation camps

Nourrir les hommes : un dictionnaire

National audienceCe dictionnaire est le résultat d’un projet original qui croise perspectives nouvelles et point sur l’état des connaissances, qui mêle articles sur les grands espaces de la planète, les principaux types de production et d’acteurs et coups de projecteurs sur des aspects moins connus. Une équipe de plus de 40 spécialistes a été réunie pour offrir plus de 500 entrées sur près de 800 pages, fruits d’un choix raisonné. Illustrant l’ouverture de la géographie aux autres sciences humaines et au monde en général, de nombreux agronomes, agro-économistes, spécialistes de relations internationales, historiens ont été conviés à participer à cet ouvrage. Il est aussi l’occasion pour des praticiens de la question de porter leurs connaissances au-delà de leur communauté scientifique, de préciser les termes d’un débat complexe, de faire partager leurs expériences, leurs craintes, leurs espoirs et peut-être, à travers une meilleure connaissance de ces enjeux, contribuer, avec les armes qui sont les nôtres, à aider à nourrir les hommes
