The impacts of climate change are addressed within large-scale development programs. However, the effects of these programs remain hard to verify using established evaluation methods. An innovative approach to answer these questions is the integration of new methods and methodological applications: The use of information derived from remote sensing data is a key mechanism to obtain in-depth information and add suitable instruments to the evaluators’ toolbox.
Remote sensing describes the collection and analysis of information of the earth’s surface by means of remotely operated collection platforms. Sensors attached to airplanes, satellites or drones capture spectral information, which are analyzed using geographic information systems (GIS). The integration of remote sensing data empowers evaluators to measure changes in the human environment, ranging from large-area phenomena such as deforestation, the extend of natural disasters, to small-scale changes, such as an assessment of household welfare or the development of regional infrastructure.
