The picture from above: Using satellite imagery to overcome methodological challenges in studying environmental displacement

Abstract:

Extreme and uncertain climate conditions adversely affect people around the world, including, in extreme circumstances, by displacing them from their homes. In today’s global climate crisis, it is critical to have a range of tools available to measure and address the scale and drivers of such forced migration. Inclusive development and the provision of time-effective humanitarian aid to those displaced requires real-time information on displacement, information that can be difficult to fully obtain through data collection on the ground. Satellite data offers an opportunity to supplement ground-level data collection for targeted intervention in areas most at-risk of displacement. The starting point of this paper is the discourse on environmental displacement, the challenges of studying this type of displacement and the opportunities information from remote sensing provide. We then showcase the applicability of such data in an embedded case study on Somalia, a country with a longstanding history of forced migration, drought and conflict.
