land use change by percentage

I have a land use shapefile that I am trying to modify in python. I have created a buffer around surface water polygons and I want to convert a percentage of the land use types that fall within the buffer to a specific land use. For example, within a 100m buffer of my stream I want to ensure that at least 10% of the region is 'naturally vegetated'. If it is not, then I want to convert 10% of changeable land (i.e. row crops) to 'vegetated'. If anyone could assist me with this one, it would be greatly appreciated.

Thanks in advance,
