Hi,

Besides the change detection functions mentioned by Bernd you may also try the TimeManager plugin:

http://plugins.qgis.org/plugins/timemanager/
http://underdark.wordpress.com/projects/time-manager/

which makes sense if you have a time series of data.

Maybe you better had urgently googled for "change detection gis",

in the second paragraph it refers to:

Hello folks,

I want to know how I will be able to conduct change detection and produce a
map from the result with QGIS? Waiting for your urgent response.

Thanks you.
