  • A New Species of Critically Endangered Edible Yam Endemic to Northern Madagascar, Dioscorea Irodensis (Dioscoreaceae) and Its Conservation
    KEW BULLETIN (2017) 72:15 ISSN: 0075-5974 (print) DOI 10.1007/S12225-017-9677-6 ISSN: 1874-933X (electronic) A new species of critically endangered edible yam endemic to northern Madagascar, Dioscorea irodensis (Dioscoreaceae) and its conservation Paul Wilkin1 , James A. Kennerley2, Mamy Tiana Rajaonah3, Geodain Meva Huckël4, Feno Rakotoarison4, Tianjanahary Randriamboavonjy3 & Stuart Cable1 Summary. Morphological character data are used to show that a distinct morphotype of Dioscorea L. from the Irodo valley (East of Sadjoavato) in Antsiranana Province of Madagascar is an undescribed species, differing in its leaf arrangement, pubescence form and male inflorescence structure from all other taxa. It is described as Dioscorea irodensis Wilkin, Rajaonah & Randriamb., illustrated and a distribution map and ecological information provided. It is known from three sites, but is likely to have been eradicated from one of them. The population that has been studied in the field contains a very low number of adult plants. Tubers have been extracted for use as food at a level that appears to be unsustainable. Thus its provisional IUCN conservation status assessment is that it is critically endangered (CR). Its vernacular name in Irodo is Bemandry. Famintinana. Ny toetra sy ny bikan’ny oviala dia azo ampiasaina hanehoana fa miavaka ny oviala iray, izay hita tao anatin’ny lohasahan’Irodo (Atsinanan’i Sadjoavato, faritanin’Antsiranana) ao Avaratr’i Madagasikara, ary tsy mbola voasoritra ny mombamomba azy. Mampihavaka azy amin’ny hafa ireto toetra manaraka ireto: ny fipetraky ny ravina, ny fisian’ny volo, sy ny firafitry ny tahom-bony lahy eo aminy. Nosoritana ho Dioscorea irodensis Wilkin, Rajaonah & Randriamb.

    HungerMapLIVE: Madagascar insight and key trends By the World Food Programme (WFP) | 27 August 2021 FOOD INSECURITY AT A GLANCE 5.5M 26.3M 1.1M Chronic hunger Population Acute hunger (undernourishment) (INSTAT Census 2018 with a IPC Phase 3+ 2.46% growth rate, 2020) (SOFI Report, 2021)1 (IPC, Apr 2021 - Sep 2021)2 The HungerMapLIVE tracks core indicators of acute hunger in near real-time. Acute hunger is measured by key indicators such as household food consumption, livelihood behaviors, child nutritional status, mortality, access to clean drinking water and other contextual factors. The HungerMapLIVE primarily tracks trends on household food consumption, consumption-based coping and livelihood changes to track multiple aspects of food insecurity. As these are outcome level 1 indicators in the Integrated Food Security Phase Classication (IPC) Framework, they can provide early indications of potential shifts in acute food insecurity. Insucient food consumption (HungerMapLIVE data)3 7.0M → 6.7M As of 29 May 2021 As of 27 August 2021 Crisis or above crisis level food-based coping strategies (HungerMapLIVE data)3 10.9M → 13.1M As of 29 May 2021 As of 27 August 2021 Methodology Note: The HungerMapLIVE includes data from two sources: (1) WFP’s continuous, near real-time monitoring systems, which remotely collect thousands of data daily through live calls conducted by call centres around the world; and (2) machine learning-based predictive models. Therefore, to note this dierentiation, this report indicates whether a region’s data is based on WFP’s near real-time monitoring systems (marked ‘ACTUAL’) or predictive models (marked ‘PREDICTED’).

    Madagascar: Cyclone Enawo Situation Report No. 2 12 March 2017 This report is issued by the Bureau National de Gestion des Risques et des Catastrophes (BNGRC) and the Humanitarian Country Team in Madagascar. It covers the period from 9 to 12 March. The next report will be issued on or around 14 March 2017. Highlights • The remnants of Intense Tropical Cyclone Enawo exited Madagascar on the morning of Friday 10 March 2017. The storm traversed nearly the length of the island over two days, affecting communities from north to south across Madagascar’s eastern and central regions. • Wind damage and widespread flooding in cyclone- affected parts of the north-east, and heavy rains and widespread flooding in eastern, central and south- eastern parts of the country has been recorded. • Favourable weather conditions since 10 March have permitted national authorities and humanitarian partners to initiate rapid assessments in north- eastern, eastern and south-eastern parts of the country. • Initial humanitarian impacts in the areas of Water, Sanitation and Hygiene (WASH), Shelter, Health, Food Security, Protection and Education, as well as Logistics have been identified. • Field coordination hubs are being jointly reinforced by national authorities and humanitarian partners in Maroantsetra and Antalaha. 295,950 84,660 83,100 58 Affected people Displaced people Damaged houses Affected districts Source: Bureau National de Gestion des Risques et des Catastrophes (BNGRC) de Madagascar, 12 March 2017 Situation Overview Intense Tropical Cyclone Enawo made landfall in north-eastern Madagascar’s Sava region on 7 March and then moved southward in an arc across central and south-eastern parts of the country as a tropical depression before exiting the country on the morning of 10 March.

CREDIT: WSSCC / DAVE TROUBA COVER: COMMUNITY-LED TOTAL SANITATION ACTIVITIES IN ANDOUNG SNAY VILLAGE, BATHEAY DISTRICT, CAMBODIA. CREDIT: WSSCC / HAKIM HADJEL NOTE TO THE READER This report provides the latest information on the Global Sanitation Fund (GSF), established by the Water Supply and Sanitation Collaborative Council (WSSCC) in 2008 to boost finances into countries with high needs for sanitation. Currently operational in 13 countries in Asia and Africa, GSF supports national programmes developed through a consultative process led by governments, with involvement of local non-governmental organizations (NGOs), associations, academic institutions, private sector companies, and international development partners. All programmes supported by GSF address the problem of inadequate sanitation and hygiene by focusing on methods of changing behaviour. These include a combination of participatory approaches, including community-led total sanitation (CLTS), securing the active involvement of local governments and other institutions and supporting the supply chain through promoting entrepreneurship in the marketing of sanitation solutions and services. In this report, the reader will find the main results in headline form for the GSF as of 31 December 2014. Also presented are cumulative numerical results in a dashboard, for the GSF as a whole and for each country that has reached the implementation phase, and descriptions of the various results indicators. The country profiles provide more detail on the national GSF-supported activities. Other sections present the GSF’s key developments in 2014, monitoring and evaluation aspects, and a full listing of active Sub-grantees.

Dans ce contexte, nous avons étudié l'évolution des spinelles chromifères et du magmatisme ultramafique à Andriamena. La région d'Andriamena fait partie du socle cristallin précambrien de Madagascar, sur la nappe de Tsaratanana. L'Unité d'Andriamena (UA) est formée d'orthogneiss et de corps mafiques-ultramafiques. Trois événements tectono-métamorphiques successifs ont affecté les formations de l'UA, ces événements sont associés à trois phases de déformation. Les lentilles des ultramafites présentent une pseudo-zonation tectonique avec une pseudo-zone de bordure de diorite et de granodiorite et une pseudo-zone de cœur avec une sous-zone médiane d'hornblendite plagioclasique et une sous-zone d'ultramafites. La chromite automorphe est le minéral majeur des rubans massifs et submassifs de chromitites des ultramafites.
