Question

why are land and water important for establishment of cities?​

Answer 1

Answer:

Water is necessary for most productive uses of land. In a growing number of countries with arid climates the main constraint to agricultural growth is the availability of water rather than land. At the same time the use of land has major impacts on both the quality and quantity of water resources.

Answer 2

Land-use planning is the process of regulating the use of land by a central authority. Usually, this is done in an effort to promote more desirable social and environmental outcomes as well as a more efficient use of resources. More specifically, the goals of modern land-use planning often include environmental conservation, restraint of urban sprawl, minimization of transport costs, prevention of land use conflicts, and a reduction in exposure to pollutants. In the pursuit of these goals, planners assume that regulating the use of land will change the patterns of human behavior, and that these changes are beneficial. The first assumption, that regulating land-use changes the patterns of human behavior is widely accepted. However, the second assumption - that these changes are beneficial - is contested, and depends on the location and regulations being discussed.
