Abstract

Global Change results from the combined effects of climate warming and human activities. Within this context, mountain regions are particularly vulnerable due to the elevation-dependent amplification of global warming. Grasslands, a key ecosystem in these environments, underpin essential socio-ecological functions, including mowing and livestock grazing, which are crucial for sustaining local communities. This study examines shifts in topsoil properties as healthy grasslands become degraded through the combined influence of grazing pressure and water erosion in a high Mediterranean mountain environment in the southern Iberian Peninsula. To this end, eco-geomorphological conditions—namely vegetation cover, surface components, geomorphic processes, and topsoil attributes (bulk density, texture, organic matter and carbon content, aggregate stability, pH, electrical conductivity, carbonate and cation contents, and water-holding capacity)—were assessed within an open experimental plot. The plot incorporated non-degraded, semi-degraded, and degraded grasslands, as well as adjacent badland surfaces. The findings indicate that (i) grassland degradation leads to significant alterations in several topsoil properties, and notably, degraded grasslands may approach the degradation status of badland surfaces; (ii) the deterioration of topsoil properties translates into a marked reduction in water availability and a decline in topsoil aggregate stability; and (iii) these changes directly affect key regulating ecosystem services delivered by grassland soils in the study area. Such impacts are especially evident in processes fundamental to geo-environmental functioning—such as carbon accumulation, water cycling, and soil erosion—under ongoing Global Change.
