Rural areas, for example, will always host some population, related to past or current rurally based economic activity, and migration of the more mobile people to cities can result in disproportionate costs in the supply of public services to the residual population. It therefore makes good public policy sense to search for untapped growth potential and look to exploit regionally specific assets in rural areas to the full. Those assets are dominated by natural resource products - food, water, forest products, minerals and scenic attractions that can be a basis for the tourism and leisure industry.
