+1, the FAO system seems quite elaborated (might be too detailed/complicated/long for OSM, not sure, but personally I'd like to have it adopted). It could be translated to OSM by using several tags i.e. you would describe the area with several tags by telling if there is vegetation or not, if the vegetation is dense or sparse, how humid the soil is, so instead of having a detailed value for every exact vegetation/coverage type you'd describe the single characteristics. This also allows for global statistics and comparison between areas that are similar in some attributes, but not all (e.g. the kind of vegetation also depends heavily on temperature and the natural environment).
