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's commercially available satellite from the same type... read more

Recently, fire hot spots decreased in consequence of heavy rainfalls (Image: NASA).

Since weeks Indonesia experiences severe forest fires in Sumatra and Kalimantan, Indonesia's half of Borneo island. Social Minister Khofifah Indar Parawansa officially confirmed the death of 19 people, as a cause of the effects of the fire haze. Due to heavy rainfall within the last days, the number of fire hot spots decreased from 1.578 to 291 on 28 October. 

Pollution levels advanced from "unhealthy" to "moderate" in Riau province on Sumatra island. Overall, more than half a million Indonesians suffer from the effects of the haze. This year’s fires had been worsened by El Niño, which further caused severe dryness in Indonesia. 

In the past, Indonesia had been impacted by several fires due to the common practice of "slash and burn agriculture", in which rainforest is burned to clear the ground for the growing of crops, like oil palm and acacia pulp, and the grazing of animals. Often fires smolder under the surface of Indonesia, continuing for a long time period. The... read more
