“…From the mid 90's there has been a growing interest in the complex interactions between ecological and hydrological processes at multiple scales (Viville and Littlewood, 1996;Rodríguez-Iturbe, 2000;Wang et al, 2012;Caylor et al, 2005;Caylor et al, 2009;Porporato et al, 2002;RodriguezIturbe et al, 1999). Because of the complex and non-linear interactions between vegetation and hydrology, few studies focus on the larger scales, such as landscapes or watersheds, where the processes are less understood (Asbjornsen et al, 2011).…”

Abstract. Natural grasses in semiarid rangelands constitute an effective protection against soil erosion and degradation, are a source of natural food for livestock and play a critical role in the hydrologic cycle by contributing to the uptake and transpiration of water. However, natural pastures are threatened by land abandonment and the consequent encroachment of shrubs and trees as well as by changing climatic conditions. In spite of their ecological and economic importance, the spatiotemporal variations of pasture production at the decadal-century scales over whole watersheds are poorly known. We used a physically based, spatially distributed ecohydrologic model applied to a 99.5 ha semiarid watershed in western Spain to investigate the sensitivity of pasture production to climate variability. The ecohydrologic model was run using a 300-year-long synthetic daily climate data set generated using a stochastic weather generator. The data set reproduced the range of climatic variations observed under the current climate. Results indicated that variation of pasture production largely depended on factors that also determined the availability of soil moisture such as the temporal distribution of precipitation, topography, and tree canopy cover. The latter is negatively related with production, reflecting the importance of rainfall and light interception, as well as water consumption by trees. Valley bottoms and flat areas in the lower parts of the catchment are characterized by higher pasture production but more interannual variability. A quantitative assessment of the quality of the simulations showed that ecohydrologic models are a valuable tool to investigate long-term (century scale) water and energy fluxes, as well as vegetation dynamics, in semiarid rangelands.

“…The positive role of forests in protecting ecosystem functions and services in watersheds or landscapes is well documented. Recent efforts have been focused on implementation of reforestation programmes to mitigate climate change impacts and to sustain other ecological functions (Schulze et al ., ; Myneni et al ., ; Calder, ; Wang et al ., ). For example, implementation of various reforestation and forest protection programmes in China has increased the forest area of 61·68 million hectares, making China a country with the largest area of planted forests in the world (State Forestry Administration of China, ).…”

How do climate and forest changes affect long‐term streamflow dynamics? A case study in the upper reach of Poyang River basin

et al. 2014

In forested watersheds, forest changes and climatic variability have been commonly recognized as two major drivers for streamflow variations. Previous research has separated their relative contributions but mainly focused on either deforestation and climate or reforestation and climate, but rarely with single studies on both. This study used the Meijiang watershed (6983·2 km2), situated in the upper reach of the Poyang Lake basin, as an example to quantify how climate and forest changes (both deforestation and reforestation) consecutively affect streamflow dynamics. Two methods, namely modified double‐mass curves and sensitivity‐based approach, were used in this study. Two breakpoints (years 1968 and 1985) with significant annual streamflow changes were detected, and together with the control period, they were then used to define three distinct periods: the control (1957–1967), deforestation (1968–1984) and reforestation (1985–2006) periods. Our results show that in the deforestation period, the average annual streamflow increment attributed to deforestation was 112·78 mm year−1, while the annual streamflow variation attributed to climate variability was −111·39 mm year−1. In the reforestation period, the average annual streamflow decrease caused by reforestation was −51·04 mm year−1, while the annual streamflow variation attributed to climate variability was 52·52 mm year−1. The sensitivity‐based approach also provided similar results. The positive and negative values in the streamflow changes suggest offsetting effects between forest changes and climate variability in both deforestation and reforestation periods. The similar magnitudes of streamflow changes demonstrate that the hydrological effects of forest changes can be as great as those caused by climate change. Copyright © 2014 John Wiley & Sons, Ltd.

“…We build on several recent discussions (e.g. National Research Council, 2008;Riveros-Iregui et al, 2011;Vose et al, 2012;Wang et al, 2012;Egginton et al, 2014) on the role of ecohydrology in addressing water resource challenges now and in the future. We focus our examples on forest watersheds in the southern US forests, as the complex mixture of public and private forest land ownership creates substantial challenges for watershed management at larger spatial scales.…”
