Agrarian Landscapes in Transition: Comparisons of Long-Term by Charles Redman, David R. Foster

By Charles Redman, David R. Foster

Agrarian Landscapes in Transition researches human interplay with the earth. With thousands of acres of agricultural land going out of construction on a daily basis, the creation, unfold, and abandonment of agriculture represents the main pervasive alteration of the Earth's setting for numerous thousand years. What occurs whilst people impose their spatial and temporal signatures on ecological regimes, and the way does this manipulation impact the earth and nature's hope for equilibrium?Studies have been performed at six long-term Ecological examine websites in the US, together with New England, the Appalachian Mountains, Colorado, Michigan, Kansas, and Arizona. whereas every one website has its personal designated agricultural historical past, styles emerge that assist in making experience of ways our activities have affected the earth, and the way the earth pushes again. The publication addresses how human actions impact the spatial and temporal buildings of agrarian landscapes, and the way this varies over the years and throughout biogeographic areas. It additionally appears on the ecological and environmental outcomes of the ensuing structural alterations, the human responses to those adjustments, and the way those responses force extra adjustments in agrarian landscapes.The time frames studied contain the ecology of the earth prior to human interplay, pre-European human interplay throughout the upward push and fall of agricultural land use, and eventually the organic and cultural reaction to the abandonment of farming, as a result of whole abandonment or a land-use swap equivalent to urbanization.

Example text

During the late 20th century, the Harvard Forest, Coweeta, and increasingly Kellogg Biological Station regions share this trajectory. But signs of greater intensity are distinctly modern. Across each study area, despite considerable differences in timing of settlement and the types of agriculture practiced, a decisive decline in the number of farms and growth in average farm size occurred during the mid 20th century. Driven by postwar urbanization and green revolution technologies, the countryside lost population everywhere at the same time.
