Population Growth and Land Use Dynamics along Urban–Rural Gradient AgEcon
Polyakov, Maksym; Zhang, Daowei.
In this study we apply a spatial conditional logit model to determine factors influencing land cover change in three contiguous counties in West Georgia between 1992 and 2001 using point (pixel) based observations of land characteristics. We found that accessibility to population and population growth affect not only development of rural lands and transition between agricultural and forestry uses, but also influence changes between forest types. The model could be used to project land use–land cover change at watershed or subwatershed level and thus serve as a valuable tool for county and city planners.

Pre-harvest Forecasting of County Wheat Yield and Wheat Quality Conditional on Weather Information AgEcon
Lee, Byoung-Hoon; Kenkel, Philip L.; Brorsen, B. Wade.
Wheat regression models that account for the effect of weather are developed to forecast wheat yield and quality. Spatial lag effects are included. Wheat yield, protein, and test weight level are strongly influenced by weather variables. The forecasting power of the yield and protein models was enhanced by adding the spatial lag effect. Out of sample forecasting tests confirm the models’ usefulness in accounting for the variations in average wheat yield and qualities.
Tipo: Conference Paper or Presentation Palavras-chave: Prediction; Protein; Spatial lag; Test weight; Weather; Wheat yield; Agribusiness; Environmental Economics and Policy; Farm Management; Production Economics; Productivity Analysis; Risk and Uncertainty.
