The type and intensity of soil erosion in a region generally depend on climatic conditions, ups and downs, soil and land use. Of these, land use is most important. Using different systems of ploughing after unconscious and non-scientific change of land use affects soil physicochemical characteristics. This fact especially in marginal lands and mountainous regions is more visible. In order to in...

Intensive land use and far-reaching alterations to the fluvial hydrosystem, made feasible by technological developments in the past century, have reduced the hydromorphological resilience of the Rhine and Meuse river basins. Because the hydromorphodynamic processes could be controlled to a greater extent, residents of the riverine areas lost their sense of the natural dynamics of river systems,...

This study analyzes the characteristics of land use/land cover change in Jordan’s Irbid governorate, 1984–2018, and predicts future land use/land cover for 2030 and 2050 using a cellular automata-Markov model. The results inform planners and decision makers of past and current spatial dynamics of land use/land cover change and predicted urban expansion, for a better understanding and successful...

Cities are experiencing rapid population growth and consequently extensive urbanization. Land-use/land-cover change is one of the important elements worldwide, which significantly affect the environment. This study aims to describe the emergence of urban heat and cool islands as a result of changes in land-use/land-cover. Land surface temperature over a 32-year period in Isfahan city, Iran was ...

Introduction: Land use mixing is one of the essential components of the urban landscape in the sustainable development of urban areas and diversity of land uses. The location of urban land-uses has a significant impact on the quality of life and efficiency of services related to different land uses. Mixed land use enables residential, work, shopping, and public services adjacent to each other a...

Land degradation threatens food production especially in smallholder farming systems predominant sub-Saharan Africa. Monitoring the effects of agricultural land uses is critical to guide sustainable intensification (SI). There are various indicators use (SLU), but conventional methods quantify their metrics complex and difficult deploy for rapid large-scale assessments. Considering that SLU dep...

In recent decades, the land use changes induced by various economic activities in agricultural ecosystems have affected many aspects of human life. This is reason why change considered as one agriculture-related environmental impacts a sustainability assessment food and bio-based products. At same time, methodology applied for quantification effects still under intensive research, stimulating s...

We studied quantitative and qualitative changes in soil organic matter (SOM) due to different land uses (reference woodland versus cultivated) on six soils from Tanzania (Mkindo and Mafiga), Zimbabwe (Domboshawa and Chikwaka), and South Africa (Hertzog and Guquka). Structural characteristics of the humic acids (HAs) were measured by Curie-point pyrolysis–gas chromatography/mass spectrometry (Py...
