The ecosystems that arise from the development of agricultural and urban areas are diverse because they exist in different areas throughout the world, from New York to New Delhi. Urban and agricultural planning requires consideration of the impact the change in environment will have on existing conditions. ""Agricultural and Urban Areas"" explores the unique ecosystems that are essentially manmade. This fascinating volume explores the importance of these areas in maintaining the food supply that supports humanity and in forming the basic social, economic, and industrial processes. Beginning with an introduction to the geography of farms and cities, this volume goes on to discuss the chemical impact urban habitats have on the environment, including waste disposal, sewage treatment, and air pollution. Developments such as the rise of different methods of agriculture and trade and the domestication of animals are presented as stepping-stones to our current systems. Conservation of plants and animals as well as original natural habitats is a subject of much contention in light of the rise and expansion of agriculture and urban life. This volume raises and examines these and other questions concerning preservation and conservation.
