ABSTRACT
This chapter explores some of the implications of megapolitan cluster and megapolitan area development patterns for such key resources as land, air, and water. It explains some surprises as well as challenges. The chapter focuses on trends in the relationship between megaregion and megapolitan development and change in the supply of farmland. With just 17 percent of the nonpublic and accessible land base in the contiguous 48 states, megapolitan clusters and their megapolitan areas account for only 11 percent of the farmland base. Air quality is another area of concern, yet it is that megapolitan clusters and megapolitan areas have a distinct advantage and opportunity to lead. Because megapolitan clusters and megapolitan areas will continue to attract the largest share of the nation's growth, but because public policy will require reductions in automobile-related air emissions, those areas will be challenged to comply.
