Land Use and Cover Change is the mapping of disturbance to the land caused by human activities.  These maps often use historical and recent satellite images to show landscape changes over time.

Petr Cizek mapped the existing, approved, and planned development of the Alberta tar sands and associated pipelines for Oilsandstruth.org.   These maps were published as wall posters, featured in numerous books, displayed in a gallery exhibit, and animated in a documentary film. 

Working with the Lubicon Lake Nation in northern Alberta, Amnesty International commissioned CIZEK ENVIRONMENTAL SERVICES to prepare the very first maps showing the encroachment of the First Nation's territory by oil/gas, logging, and tar sands resource extraction since the 1970's.

In Manitoba, Petr Cizek pioneered the use of historical maps and satellite imagery to calculate the amount of land flooded by hydro-electric dams for Trapline 18 and the Southern Chiefs Organization.  He then advised consultants for the Peguis First Nation, about how to use these techniques in their submission to the Clean Environment Commission hearings on the proposed Keeyask hydro-electric project.

Dr. Cizek continues to advise First Nations in Manitoba surrounding Lake Winnipeg in Manitoba about mapping and analysing flooding and shoreline change caused by hydro-electric development.
