Madagascar: Cyclone Chedza Emergency Plan of Action (EPoA) Operation n° MDRMG011


A. Situation analysis

Description of the disaster

From 5 January 2015, pressure from Inter Tropical Convergence Zone (ITCZ) caused continuous rainfall, leading to flooding across Madagascar, with the capital city of Antananarivo (in Grand Tana) among the areas that have been worst affected. Due its location, Antananarivo is prone to flooding and the situation has been exacerbated by an increase in buildings constructed illegally in areas that have in the past acted as courses in which the rain waters could reduce.On 16 January, Tropical Cyclone Chedza landed in Madagascar, which caused Antananarivo’s pump station (in charge of the city’s disposal of rain and flood waters) to cease operation, and caused the levels of surrounding rivers to increase even further, result in a red alert (or immediate danger warning) being issued. It has also resulted in in widespread destruction in the central (Analamanga region), southern (Vatovavy Fitovinany and Atsimo Atsinanana) and western (Menabe region) parts of the island.

As of 30 January 2015, according to preliminary assessments carried out by the Malagasy Red Cross an estimated 80,000 people remain affected (Malagasy Red Cross Society), with more than 20,000 living in temporary shelter through the country, including over 16,000 in Antananarivo (UNOCHA). Displaced persons in other regions are gradually returning home. Up to 68 people have died as a result of floods (UNOCHA). Water supply and sanitation infrastructures have been flooded (19 in total) and contaminated (5 in total), which has increased the risk of waterborne diseases, particularly in large inundated cities including Antananarivo
