AB - This paper presents a summarized compilation of the results of research performed in wet Andean paramo ecosystem in southern Ecuador using paired micro-catchments in order to study the land-use change impacts on its hydrology. The comparative analysis revealed that extensive livestock seems not to affect the hydrological response, primarily due to the low animal density, while the main impact of cultivation is the reduction in the regulation function of the catchment with a large increase in the magnitude of peak flows, a decrease of base flows, and, in general, a reduction of its buffering capacity. Moreover, a decrease in water yield, which is possibly caused by a higher evapotranspiration, is observed. On the other hand, pine plantations produce a decrease of annual water yield as a consequence of increased evapotranspiration. Furthermore, research results revealed that vertical infiltration through the soil is dominant under wet conditions, whereas preferential flow within the organic horizon to the underlying mineral horizon is dominant during low intensity rains. Only during long rain events saturated excess surface flow is observed; otherwise, near surface lateral flow in the organic layer occurs. Preliminary results show this water movement process in the subsoil is not affected by land-use change.
