  8. 8. Urban Planning - The growth of Bangkok needs to be planned and regulated. - As cities expand, they take more lands. Bangkok is located within the river basin (rich farmland), without control, valuable farmlands would be taken over to accommodate the expansion of the city. - The Department of Public Works and Town and Country Planning is responsible for this
