Rural and suburban development has been and will continue to depend heavily on the use of onsite private sewage systems. The exodus to rural settings combined with changing technologies for sewage disposal that reduce site limitations to development have raised a broad set of land use, infrastructure, and environmental concerns. In a study of development in Wisconsin, we found that the type of ...

  Applying of intensive cultivation especially in marginal and sensitive regions, after conversion of rangelands to cropland farms, commonly causes reduction in soil quality, and thus an increase in soil degradation, erosion and runoff. This study was conducted to evaluate the land use change effects on some soil physical and chemical properties such as mean weight diameter (MWD), soil organic ...
