Oil palm plantations have expanded rapidly in recent decades. This large‐scale land‐use
change has had great ecological, economic, and social impacts on both the areas converted …

Information on sediment and nutrient export from catchments and about related erosive
processes is required by catchment managers and decision-makers. Many models exist for …

Land-use change models are used by researchers and professionals to explore the
dynamics and drivers of land-use/land-cover change and to inform policies affecting such …

This article examines how the methods and data sources used to generate DEMs and
calculate land surface parameters have changed over the past 25years. The primary goal is …

Water erosion creates negative impacts on agricultural production, infrastructure, and water
quality across the world. Regional-scale water erosion assessment is important, but limited …

Of particular importance to the study of large-scale phenomena in physical geography is the
modifiable areal unit problem (MAUP). While often viewed as only a problem in human …

Terrain attributes are the most widely used predictors in digital soil map**. Nevertheless,
discussion of techniques for addressing scale issues and feature selection has been limited …

Digital elevation models (DEMs) represent the topography that drives surface flow and are
arguably one of the more important data sources for deriving variables used by numerous …

Topography is an important land-surface characteristic that affects most aspects of the water
balance in a catchment, including the generation of surface and sub-surface runoff; the flow …

Gully erosion has been identified as an important soil degradation process and sediment
source, especially in arid and semiarid areas. Thus, it is useful to identify the spatial …
