"Changes in land use transform the landscape and can contribute to the loss of natural land. This can affect the environment and result in population declines in wildlife species. Loss of natural areas such as forests or wetlands can disrupt the ecosystem services that support human wellbeing, resulting in a decline in air and water quality, an increase in air and water temperatures and an increased risk of flooding. As cities grow outward, urban expansion often encroaches on surrounding areas, including agricultural land, forests and other natural areas. When cropland is lost to urban growth, there can be additional pressure to convert natural areas to cropland to increase agricultural capacity. By tracking changes between forests, cropland and settlement land uses, it is possible to measure how human activities are changing these landscapes"--Page 5.
