a new point that i would make, however, in many of those arguments which relate to the impossible, or alleged availability of additional windfall sites, and land on the inner greenbelt boundary, but i think the analysis which is er carried out is a simplistic one, because it solely relates to residential land requirements, there is no erm attempt to erm bring into the equation whether there is land available for the related employment necessary for that additional residential development, whether there is land available for schools, shops, and mr davis's recreation uses, and so on, and all those will very considerably increase the amount of land required to be released to support residential development, wherever it is located, and that is something which i believe has not been properly taken into account.
