9817743ParkThe researchers would use remote-sensing images from 1982-98 to document urban change in six African cities and contrast what happens in urban areas with development in urban hinterlands. In work weighted toward the poorer sections of the cities, households would be interviewed to learn about livelihood strategy histories, relationships to natural resource use, and impacts of changes in urban structure.The results would be used to assess the effects of various projects and to initiate hypotheses that could be tested in later studies. A preliminary hypothesis is that the process of urbanization in arid Africa has produced a new poor, people whose lives are shaped more by collective use of aid than by individual maximizing behavior. If this is true, the information can be used in urban planning as well as in furthering the understanding of African urbanization.

研究人员将使用1982- 1998年的遥感图像来记录六个非洲城市的城市变化，并将城市地区的变化与城市腹地的发展进行对比。在侧重于城市较贫困地区的工作中，将对家庭进行访谈，以了解生计战略的历史、与自然资源利用的关系以及城市结构变化的影响。研究结果将用于评估各种项目的效果，并提出可在以后的研究中加以检验的假设。一个初步的假设是，非洲干旱地区的城市化进程产生了一种新的穷人，这些人的生活更多地是由集体使用援助而不是个人最大化行为塑造的。如果这是真的，这些信息可以用于城市规划以及进一步了解非洲城市化。
