Earth observation and environment is about gaining a better understanding of the earth, its composition, how it functions, and the effects that human behaviour can cause.
Integral to this area is the examination of the effects of climate change, pollution, over-use of natural resources, and how these issues can be tackled.
Scientists use data from Earth observation satellites to monitor global and regional changes in the environment, as well as to learn more about the Earth system and improve predictions of future environmental conditions.
