“…The results highlight the importance of coffee to provide the environmental function of carbon sequestration and other services widely discussed in other scientific studies, such as conservation of biodiversity, pollination, regulation of microclimate and extremes events, pest control diseases, and cultural services (Perfecto et al, 2005(Perfecto et al, , 2007Philpott et al, 2008aPhilpott et al, , 2008bMéndez et al, 2010;Solis-Montero et al, 2005;Priess et al, 2007;Ricketts et al, 2004;Vergara & Badano, 2009;Lin, 2007;Siles et al, 2010;Perfecto & Vandermeer, 2006;Vandermeer et al, 2009;Toledo & Moguel, 2012). According to the challenging economic situation being experienced by the coffee sector (Bray et al, 2002), it would be essential to implement new actions that promote sustainable practices and, in turn, improve farmer's income.…”

Abstract. Although regenerating forests make up an increasingly large portion of humid tropical landscapes, little is known of their water use and effects on streamflow (Q). Since the 1950s the island of Puerto Rico has experienced widespread abandonment of pastures and agricultural lands, followed by forest regeneration. This paper examines the possible impacts of these secondary forests on several Q characteristics for 12 mesoscale catchments (23-346 km 2 ; mean precipitation 1720-3422 mm yr −1 ) with long (33-51 yr) and simultaneous records for Q, precipitation (P ), potential evaporation (PET), and land cover. A simple spatially-lumped, conceptual rainfall-runoff model that uses daily P and PET time series as inputs (HBV-light) was used to simulate Q for each catchment. Annual time series of observed and simulated values of four Q characteristics were calculated. A least-squares trend was fitted through annual time series of the residual difference between observed and simulated time series of each Q characteristic. From this the total cumulative change (Â) was calculated, representing the change in each Q characteristic after controlling for climate variability and water storage carry-over effects between years. Negative values ofÂ were found for most catchments and Q characteristics, suggesting enhanced actual evaporation overall following forest regeneration. However, correlations between changes in urban or forest area and values ofÂ were insignificant (p ≥ 0.389) for all Q characteristics. This suggests there is no convincing evidence that changes in the chosen Q characteristics in these Puerto Rican catchments can be ascribed to changes in urban or forest area. The present results are in line with previous studies of mesoand macro-scale (sub-)tropical catchments, which generally found no significant change in Q that can be attributed to changes in forest cover. Possible explanations for the lack of a clear signal may include errors in the land cover, climate, Q, and/or catchment boundary data; changes in forest area occurring mainly in the less rainy lowlands; and heterogeneity in catchment response. Different results were obtained for different catchments, and using a smaller subset of catchments could have led to very different conclusions. This highlights the importance of including multiple catchments in land-cover impact analysis at the mesoscale.

“…We set the surface reservoir maximum storage capacity A X for our coffee AF system equal to 4 × 10 −4 m using data from Siles et al .(2010b). The two parameters of the evapotranspiration routine were taken as: REW c = 0.4 from Granier et al (1999) and r m = 0.8 from field measurements of T ET −1 0 (data not shown).…”

“…Some experimental basins are located in the tropics, like those in Brazil, Costa Rica, Guadeloupe and Panamá (Charlier et al, 2008;Fujieda et al, 1997;Genereux et al, 2005;Kinner and Stallard, 2004), but no coffee AF basins have been equipped so far. Some reports are available for coffee AF systems but at the plot level and for some particular fluxes such as throughfall and stemflow (Siles et al, 2010b), tree and coffee transpiration (Dauzat et al, 2001;van Kanten and Vaast, 2006), surface runoff (Harmand et al, 2007), energy balance and latent heat flux (Gutiérrez et al, 1994). To our knowledge, there is no comprehensive study of the water balance partitioning of coffee AF systems at the basin level, including the behaviour of the aquifer.…”

Abstract. The profitability of hydropower in Costa Rica is affected by soil erosion and sedimentation in dam reservoirs, which are in turn influenced by land use, infiltration and aquifer interactions with surface water. In order to foster the provision and payment for Hydrological Environmental Services (HES), a quantitative assessment of the impact of specific land uses on the functioning of drainage-basins is required. The present paper aims to study the water balance partitioning in a volcanic coffee agroforestry microbasin (1 km 2 , steep slopes) in Costa Rica, as a first step towards evaluating sediment or contaminant loads. The main hydrological processes were monitored during one year, using flume, eddy-covariance flux tower, soil water profiles and piezometers. A new Hydro-SVAT lumped model is proposed, that balances SVAT (Soil Vegetation Atmosphere Transfer) and basin-reservoir routines. The purpose of such a coupling was to achieve a trade-off between the expected performance of ecophysiological and hydrological models, which are often employed separately and at different spatial scales, either the plot or the basin. The calibration of the model to perform streamflow yielded a Nash-Sutcliffe (NS) coefficient equal to 0.89 for the year 2009, while the Correspondence to: F. Gómez-Delgado (fgomezd@ice.go.cr) validation of the water balance partitioning was consistent with the independent measurements of actual evapotranspiration (R 2 = 0.79, energy balance closed independently), soil water content (R 2 = 0.35) and water table level (R 2 = 0.84). Eight months of data from 2010 were used to validate modelled streamflow, resulting in a NS = 0.75. An uncertainty analysis showed that the streamflow modelling was precise for nearly every time step, while a sensitivity analysis revealed which parameters mostly affected model precision, depending on the season. It was observed that 64% of the incident rainfall R flowed out of the basin as streamflow and 25% as evapotranspiration, while the remaining 11% is probably explained by deep percolation, measurement errors and/or inter-annual changes in soil and aquifer water stocks. The model indicated an interception loss equal to 4% of R, a surface runoff of 4% and an infiltration component of 92%. The modelled streamflow was constituted by 87% of baseflow originating from the aquifer, 7% of subsurface nonsaturated runoff and 6% of surface runoff. Given the low surface runoff observed under the current physical conditions (andisol) and management practices (no tillage, planted trees, bare soil kept by weeding), this agroforestry system on a volcanic soil demonstrated potential to provide valuable HES, such as a reduced superficial displacement-capacity for fertilizers, pesticides and sediments, as well as a streamflow regulation function provided by the highly efficient mechanisms Published by Copernicus Publications on behalf of the European Geosciences Union. 370 F.
