This paper presents a new approach to understanding the effects of economic factors on biodiversity change over the long run. We illustrate this approach by studying the determinants of biodiversity change in upland Scotland from 1600-2000. The measure of biodiversity used is a proxy for plant species diversity, constructed using statistical analysis of paleoecological (pollen) data. We assembl...

0099-1112/04/7002–0217/$3.00/0 © 2004 American Society for Photogrammetry and Remote Sensing Abstract A rule-based expert system has been the most common artificial intelligence (AI) technique for system integration with geographic information systems (GIS) because of its simple rule structure. In this paper, a rule-based expert system is presented that uses an interactive question-and-answer s...

Although many low-income urban areas are highly walkable by conventional measures such as population density or land use mix, chronic diseases related to lack of physical activity are more common among residents of these areas. Disparities in neighborhood conditions may make poor areas less attractive environments for walking, offsetting the advantages of density and land use mix. This study co...

Change in urban construction land use is an important factor when studying urban expansion. Many scholars have combined cellular automata (CA) with data mining algorithms to perform relevant simulation studies. However, the parameters for rule extraction are difficult to determine and the rules are simplex, and together, these factors tend to introduce excessive fitting problems and low modelin...

Satellite remote sensing technology and the science associated with evaluation of land use and land cover (LULC) in an urban region makes use of the wide range images and algorithms. Improved land management capacity is critically dependent on real-time or near real-time monitoring of land-use/land cover change (LUCC) to the extent to which solutions to a whole host of urban/rural interface dev...

During the twentieth century, the natural landscape of the Florida peninsula was transformed extensively by agriculture, urbanization, and the diversion of surface water features. The purpose of this paper is to present a numerical modeling study in which the possible impacts of this transformation on the warm season climate of the region were investigated. For three separate July–August period...

The aim of this study is to cross-verify of multiple logistic model at Korea using a Geographic Information System (GIS). Landslide locations were identified in the 3 study areas from interpretation of aerial photographs and satellite image, field surveys, and maps of the topography, soil type, forest cover and land cover were constructed to spatial data-sets. The factors that influence landsli...

A database of global agricultural primary production has been constructed and used to estimate its energy content. The portion of crops available for food and biofuel after postharvest losses was evaluated. The basic conditions for agriculture and plant growth were studied, to ensure sustainable scenarios regarding use of residues. The available energy contents for the world and EU27 was found ...

Farm households in developing countries are generally credit constrained. This forces them to simultaneously take production and consumption decisions. In this paper, a two-period lifecycle model of the farm household is constructed and the household’s investment response to changes in land and agricultural output prices are derived theoretically. It is shown that in the absence of credit marke...
