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…

Facebook has published new population density maps covering most of the African continent and countries of the Asia-Pacific region in June 2019. Using artificial intelligence (AI), these maps help organizations to respond to natural disasters, and scientists to assess the impact of climate change and urbanization on people’s lives. As soon as almost the entire world population is covered by the project, population distribution in remote areas will be better determinable by humanitarian agencies. In that way, health workers will be able to better reach households and relief workers to better distribute aid. 

For its population density maps, Facebook used a combination of machine learning techniques, high resolution satellite imagery and population data; no Facebook data was used nor did the census and satellite data used contain any personal data. The satellite maps used were created using DigitalGlobe'…

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…
