We present an analysis of the impacts of weather change and large-scale vegetation conservation programs on the vegetation dynamics in China’s Loess Plateau from 2000 through 2009. We employed a multiple lines of evidence approach in which multi-scale data were used. We employed Normalized...

This paper presents a method to optimise the calibration of parameters and land use transition rules of a cellular automata (CA) urban growth model using a self-adaptive genetic algorithm (SAGA). Optimal calibration is achieved through an algorithm that minimises the difference between the...

In order to address the challenges in coastal regions, there is the need to understand the extent and impacts of past changes and their implications for future management. Land use data and remotely-sensed imagery are often used to provide insights into these changes. Often, however, existing...
