Floods are among the most frequent natural hazards around the world, as well as in Africa, and can trigger devastating disasters among the most vulnerable communities. Climate change, and inadequate land-use/land-cover changes can exacerbate this situation and may erode hard-won gains in many developing countries. The first step to reduce the impacts of such floods is to understand the dynamics of floods throughout the floodplains more precisely.

To support an improved understanding of floods in West Africa, the Centre for Space Science and Technology Education (CSSTE) is leading the project entitled Multi-Scale Flood Monitoring and Assessment Services for West Africa (MiFMASS) that relies on Earth observation satellite data. The main objective of this project is to create a flood event database, which will include historical and real-time data for individual, company and government use across West Africa.

On 19 September, Bing announced that the United Republic of Tanzania and Uganda are the first African countries to have an open buildings dataset. As a result of a joint venture between Bing Maps, Microsoft Philanthropies and Humanitarian OpenStreetMaps (HOTOSM), 18 million building footprints have been established, of which 7 million in Uganda and 11 million in the United Republic of Tanzania. Datasets like these that are created with satellite data, can prove vital for disaster relief efforts, which are often obscured due to the lack of maps and therewith a lack of coordination in the area affected by the disaster.

The World Disasters report of 2018 by the International Federation of Red Cross and Red Crescent Societies (IFRC) states that 2 billion people were affected by disasters in the last ten years. In 2017, 201 million people needed humanitarian assistance and 18 million people were displaced due to weather-related disasters. Many of these…

Kenya’s president has declared the worsening drought in the country a national disaster.

According to the National Drought Management Authority (NDMA) the drought has been worsening in most Kenyan counties, now affecting nearly half the country. Forage conditions are drier than usual because of lower than usual rainfall conditions and also the extended dry period between the short and long rains in 2016. The number of people in need of food has risen from 1.3 million to 2.7 million last year.

Low levels of rainfall affected the crop performance in certain parts of the country, especially around Lake Victoria and in parts of the western and central region. Maize, beans and sorghum yields have experienced a significant drop of nearly 50% and in some counties, maize is said to be near total failure. 

The drought has also left the livestock in danger, causing unusual patterns of livestock migration. According to FAO’s Joseph Matere, it is going to get worse this…
