Excerpt from Some Trends in Land Classes I and II: An Analysis of Two Areas in Southern New York In 1927, studies were made in several areas throughout southern and central New York, the results of which are reported in Bulletin 490, Abandoned Farm Areas in New York. In general these studies show that the abandoned areas are naturally low in productivity. This condition is due primarily to poor soil and a short growing season resulting from high elevations. The size and condition of buildings, the amount of livestock kept, the kind of crops grown, and the yields per acre are all evidences of this low productivity. The almost exclusive use of the cleared land for small grains, hav and pasture, and the fact that the yields were from one-third to one-half less than State average in 1926 during a comparatively good farming period and under the management of experienced farmers is substantial evidence that cannot be overlooked (table Furthermore, all facts in the history of these areas would bear out the conclusion that the present low productivity is not a new thing and that it is primarily a result of inherent inability to pro duce rather than soil depletion or poor management.

People are constantly changing the land surface through construction, agriculture, energy production, and other activities. Changes both in how land is used by people (land use) and in the vegetation, rock, buildings, and other physical material that cover the Earth's surface (land cover) can be described and future land change can be projected using land-change models (LCMs). LCMs are a key means for understanding how humans are reshaping the Earth's surface in the past and present, for forecasting future landscape conditions, and for developing policies to manage our use of resources and the environment at scales ranging from an individual parcel of land in a city to vast expanses of forests around the world. Advancing Land Change Modeling: Opportunities and Research Requirements describes various LCM approaches, suggests guidance for their appropriate application, and makes recommendations to improve the integration of observation strategies into the models. This report provides a summary and evaluation of several modeling approaches, and their theoretical and empirical underpinnings, relative to complex land-change dynamics and processes, and identifies several opportunities for further advancing the science, data, and cyberinfrastructure involved in the LCM enterprise. Because of the numerous models available, the report focuses on describing the categories of approaches used along with selected examples, rather than providing a review of specific models. Additionally, because all modeling approaches have relative strengths and weaknesses, the report compares these relative to different purposes. Advancing Land Change Modeling's recommendations for assessment of future data and research needs will enable model outputs to better assist the science, policy, and decisionsupport communities.
