Researchers have been coupling geographic information systems (GIS) data handling and processing capability to watershed and waterquality models for many years. This capability is suited for the development of databases appropriate for water modeling. However, it is rare for GIS to provide direct inputs to the models. To demonstrate the logical procedure of coupling GIS for model parameter extr...

The need to reduce the use of chemical inputs in agricultural ecosystems requires studying integrated ecological processes and developing new tools helping to manage them. In particular, designing landscape management strategies is a new way to improve the efficiency of services provided by biodiversity as biological control or pollination. Individual-based models are useful to better understan...

Abslraci-This article focuses on developing a predictive method to simulate the distribution of agricultural land use patterns based on remote sensing and a multiple choice logit model. A multiple choice model is developed to determine land use options such as rice cropland, maize cropland, wheat cropland, soybean cropland and so on. The independent variables are grouped under two categories: b...

Addressing the global challenges to water security requires a better understanding of humanity's use of water, especially the agricultural sector that accounts for 70% of global withdrawals. This study combined high resolution-data with a GIS system to analyze the impact of agricultural practices, crop type, and spatial factors such as drainage basins, climate, and soil type on the Water Footpr...

By evaluation of an extensive yield database a biomass yield model [bym] was developed. It is based on site specific yield functions and crop rotation algorithms. In combination with geodata it is possible to calculate regional biomass on the level of municipalities. The conversion to a GIS was performed in Visual Basic for Application (VBA). Exemplary winter rye production for bioethanol in th...

Abstract Purpose The sediment supply to rivers, lakes, and reservoirs has a great influence on hydro-morphological processes. For instance, long-term predictions of bathymetric change for modeling climate scenarios require an objective calculation procedure load as function catchment characteristics hydro-climatic parameters. Thus, the overarching this study is develop viable assessment methods...
