Population Exposure - Heavy Rains in Mozambique & Zimbabwe, January 2017

Situation Overview

Torrential rains falling in central and southern Mozambique, from the 1st to the 18th of January, 2017, have resulted in flooding. Precipitation levels over the last seven days reached over 650 mm, which exceeds average precipitation levels of 209.3 mm according to The World Bank Group. Around 5,000 people of Dondo district, Sofala province, are without road communication with the rest of Mozambique. Moving around the district is only possible by boats (Club of Mozambique). Rivers, such as the Buzi River in southern Mozambique, have overflowed.

In Zimbabwe, the Marimba River in Budiriro, near the capital Harare, overflowed from its banks after several days of heavy rain. Families were forced to evacuate their homes on the 13th of January, 2017 (FloodList).

This report provides a population per precipitation accumulation zone analysis over Mozambique and Zimbabwe. The analysis was conducted according to the estimated precipitation accumulation data derived from the Global Precipitation Measurement (GPM) dataset of the last seven days (12th to the 18th of January, 2017) at a spatial resolution of approximately 10km. The population data was derived from WorldPop.

According to our analysis approximately 600,000 people in Mozambique may be exposed to over 500 mm of precipitation and 1,000,000 people may be exposed to 300-500 mm of precipitation over the last seven days. Furthermore, for Zimbabwe, approximately 200,000 people may be exposed to 300-500 mm of precipitation over the last seven days from the 12th to the 18th of January, 2017.
