Prairie or grassland together with lands that have been designated as agricultural lands are one of the largest land cover and land use types that exist today. While prairie lands provide habitat to a wide variety of animals and organisms, and agricultural lands support human population, these lands, especially those in the immediate vicinity of large urban areas are giving way to urbanization at alarming rates. In particular, prairie lands are often viewed as wastelands because many do not fully understand their benefit to the effective functioning of the urban ecosystem. On the other hand, many agricultural lands are being converted to several urban uses because of the high economic returns from the sale of these lands. In this study, we utilized SPOT satellite data to investigate the loss of prairie and agricultural lands to urban expansion in six sub-watersheds in the Kansas City metropolitan area of Missouri State in the USA. Our results revealed the alarming rate of loss in these land cover and land use types within the period understudied. These results provide baseline information that can support a data-driven and sustainable alternative paths to urban expansion in our study area.
