This paper looks at the economics of conversion and fragmentation of forest land. The forestry economics literature has generally focussed on the management of a single stand for timber and non-timber forest benefits with little attention being paid to forest level land use decisions, and in particular forest stand interactions. As noted by Bowes and Krutilla (1989), the focus on a single stand...

Understanding the complexity of urban expansion requires an analysis of the factors influencing the spatial and temporal processes of rural-urban land conversion. This study aims at building a statistical land conversion model to assist in understanding land use change patterns. Specifically, GIS coupled with a logistic regression model and exponential smoothing techniques is used for exploring...

This paper provides an analytical model that makes sense of this observation, featuring fiscal decentralization, local governments as custodians of land use ...

The main objective of this study is to evaluate the land-use change and its relationship with its driving factors in the loess hilly region. In this study, a case study was carried out in Pengyang County. We set two land-use demand scenarios (a baseline scenario (scenario 1) and a real land-use requirement scenario (scenario 2)) during year 2001-2005 via assuming the effect of driving factors o...
