An analysis of recent and historical satellite imagery collected over the past forty years was carried out for Lake chad in West Africa, the Sundarbans along the India-Bangladesh border, Papua in Indonesia, the Paranaense Forest around Itaipu Dam and Iguazu Falls at the juncture of Argentina, Brazil and Paraguay, and the Ataturk Dam and the Harran Plain in South Eastern Turkey to provide scientific evidence of environmental change taking place in these ecologically significant regions of the world. While it can be difficult to pinpoint exact causes of change to the environment, the report documents environmental impacts of development, tourism, globalisation, human uses, engineering, climate change and a host of other factors.
