The article discusses a study which examined the spatial variability of runoff and erosion rates in vineyards of Northeastern Spain. The study examined plots with high disturbance (HD) and low disturbance (LD) of the soil profile and evaluated whether soil surface properties were conditioning runoff and erosion rates. It discusses soil and rainfall characteristics as well as runoff differences in the HD and LD plots and differences in sediment concentration.

The article presents a study on the agricultural trajectories and farming systems in the Priorat region in Spain. In the Priorat region, as well as in the other mountain regions of Mediterranean European countries, the intensification of crops is said to be based on either land leveling or terracing, and the abandonment of usual land use management practices. One of the objectives of the study is to relate the coexisting farming systems in Priorat to the landscape impacts they involve. The researchers combined multivariate statistical techniques to understand the heterogeneity of farming systems on a local scale.
