Anthropogenic changes in the suspended load transportation by and sedimentation rates of the river Vistula, Poland
Evidence is presented that regulation works on the Vistula channel have introduced very significant and rapid changes in the magnitude of river load transportation and sedimentation. It is acknowledged that human interference represents the most
significant cause of change in the Vistula catchment within historical times. The alluviation of the Vistula valley floodplain as described here, which was initiated about 150 years ago, may be compared with the equally rapid changes of load transportation
Contributions to change in the input-output model : the search for inverse important coefficients
Les AA. expliquent la relation entre les changements des coefficients structurels d'entrée-sortie et les coefficients de la matrice inverse de Leontief. Il s'agit de comprendre comment les changements structurels dans un secteur se transmettent à
l'ensemble de l'économie et de mettre à jour des tables contenant des informations limitées. Identification des coefficients qui déterminent l'apparition de changements inverses. Une procédure sélective et systématique ne nécessite pas la possession de

This project was carried out as part of a national research project on the impact of climatic change on regional hydrology. The main objective was to assess the impact of climate change on overbank sedimentation rates on the embanked floodplains
in space and time. As a result of climatic change, floodplain sedimentation rates may increase by a factor 1.5 to 2 over the forthcoming century. -(AGD)
The changing map of American poverty in an era of economic restructuring and political realignment
The A. argues that conservative theory falters when the spatial dynamics of poverty is considered in the United States. The changing map of American poverty reflects the geographic contours of recent transformations in the American political economy

Phytolith and carbon isotope evidence for late Quaternary vegetation and climate change in the Southern Black Hills, South Dakota
Analyses of phytoliths and carbon isotopes document the rate and nature change in late Quaternary grasslands in the Red Valley of the southern Black Hills. This paper will evaluate the temporal sensitivity and spatial limits of the methods.

These areas make a substantial contribution to the regulation of landscape change. Visual changes to landscapes are predicted through impact assessment procedures and computer manipulation of photographic images. The methodological requirements
are outlined. Such approaches to landscape change are an essential foundation for the development of environmental cost-benefit analyses.
