The Challenge | The Land Where Displaced People Settle

Characterize land cover/land use at informal settlements of displaced populations using NASA satellite datasets.


Help-Ally is aimed at helping displaced people.



The number of people displaced from their home communities because of natural disasters or conflict has grown to 68.5 million people worldwide. Approximately 40 million of these people are Internally Displaced People (IDP), since they remain inside their country's borders. Another 25.4 million leave their countries and settle abroad as refugees, with the remaining roughly 3.1 million being at an intermediate stage of seeking asylum.
