Vulnerability to Natural Shocks: Assessing the Short-Term Impact on Consumption and Poverty of the 2015 Flood in Mozambique
Vincenzo Salvucci, Ricardo Santos
Abstract
Mozambique is among the most disaster-prone countries in the world. A bigger than usual, and mostly unexpected, flood occurred in the central-northern region of the country in the first few months of 2015, causing huge damage to infrastructures. In this paper, we use a nationally representative household budget survey that was being carried out in the field during those months to assess the short-term impact of the 2015 flooding on household consumption and poverty levels. Applying a difference-in-difference approach, we find that, for those exposed to the flood, consumption reduced significantly in the short term, in the range of 11–17%, depending on the specification, on the estimation procedure implemented or on the subsample of households selected. Poorer households, and especially households living in rural areas, seem to have been affected significantly more. Poverty levels also increased due to the flood, by about 6 percentage points. These results are relevant for policy planning and natural disaster management, as well as for ex-ante vulnerability assessment in Mozambique and other risk-prone developing countries with similar characteristics.
