When I look at this, I see that the 'most affected areas' are all along the Pak-Afghan border. And when I scroll down and read the little table that shows the number of 'incidents' for all the provinces.. it says to me that much of Afghanistan is in (relative) peace. Look at Bamyan and Panjsher for example: they only have a total of 4 reported incidents in 2007 and 2008 in that time frame.
The only thing that this map/table show me, are that border movements, and thus attacks in border regions are up. Why? Your guess is as good as mine. Everyone has offensives in warzones. This could be thiers (regardless of whether or not it is prolonged).
I also agree with Carbon 14: I would like to know what is classed as an 'incident.' Is a lone round fired counted as an incident if it is reported, ... and a full fledged contact with a number of fighters left out because it wasn't reported?
Regardless, I guess it shows a decent, albeit vague, overview.
