Purpose: This study systematically reviewed and synthesised all the scientific literature that has so far been conducted on the ecosystem services of the UK’s Silvopastoral National Network Experiment, the Henfaes Silvopastoral Systems Experimental Farm of Bangor University, Wales, and other studies in temperate Europe from 1988 to 2012 to establish what has been done to date, the benefits and contributions to our knowledge base, and potential knowledge gaps and priorities for future research.Methodology: All available papers and grey literatures, since the inception of the UK’s Silvopastoral National Network Experiment in 1988, were extracted and reviewed primarily by accessing various electronic databases and existing library collections. The research papers were split into peer-reviewed (published) and non-peer-reviewed (unpublished) papers. The ecosystem services framework was used to relate the four major categories of ecosystem services (provisioning, regulating, cultural and supporting) to the scientific domain of the research studies. The scientific domains addressed include timber or wood-fuel potential, pasture/livestock management, carbon sequestration, soil improvement, water management, and biodiversity enhancement.Findings:  Results show that 66 research studies were conducted over the 20-year study period on ecosystem services of which 45% were produced based on studies at Henfaes Silvopastoral Systems Experimental Farm, 32% at UK’s Silvopastoral National Network Experiment, 12% were from other silvopastoral systems trials in the UK, and 11% were from European-wide silvopastoral systems studies. The trendline indicated that the number of annual studies on ecosystem services were greatest in the mid and late 1990s than in any other time over the 20-year study period. The studied ecosystem services dealt with provisioning services (40%), regulating services (13%), and supporting services (47%). The scientific domains addressed include timber or wood-fuel potential (20%), pasture/livestock management (20%), biodiversity (20%), carbon sequestration (13%), water management (15%), and soils (12%).Unique contribution to theory, practice and policy: It is hoped that the results of this study will lead to better understanding of the economic and environmental implications of silvopastoral system, and hence generate more attention towards accelerating its adoption and institutionalization in national rural development policies.

<p>Se estimó el secuestro de carbono y uso de agua en seis sistemas silvopastoriles basados en la combinación de <em>Brachiaria brizantha </em>e <em>Hyparrhenia rufa </em>con especies maderables nativas en el trópico seco. Se empleó un diseño experimental de bloques completos al azar con parcelas divididas, donde las pasturas (<em>B. brizantha </em>e <em>H. rufa</em>) fueron las parcelas principales y los maderables (<em>Dalbergia retusa</em>, <em>Dyphisa robinioides </em>y <em>Pithecellobium saman</em>) las subparcelas. Se evaluó el carbono total en la biomasa aérea (árbol y pastura) y debajo del suelo (suelo y raíces), y la transpiración arbórea mediante el método de “flujo de savia” usando 18 individuos (3 repeticiones por especie arbórea por pastura). El mayor almacenamiento de carbono en la biomasa aérea la realizó <em>D. robinoides </em>(4,4 t C/ha), y en la pastura, <em>B. brizantha </em>con <em>P. saman </em>(5,8 t C/ ha). La mayor acumulación de C en raíces finas (d &lt; 2 mm) se encontró en los primeros 20 cm del suelo. La mayor cantidad de carbono en raíces se encontró en árboles que crecieron con <em>B. brizantha </em>(1,1 t C/ha) y en pasturas que crecen con la asociación <em>B. brizantha </em>y <em>D. robinioides </em>(1,5 t C/ha). El 55% de C en el suelo se encontró en los primeros 20 cm. La mayor transpiración se encontró en <em>D. robinioides </em>(1,5 mm/día) y la menor, en <em>P. saman </em>(0,3 mm/día). Los sistemas silvopastoriles evaluados resultaron promisorios gracias a su alto secuestro de carbono y su uso de especies maderables con alta eficiencia de uso de agua.  </p><p> </p><p><strong>Carbon sequestration and water use in silvopastoral systems with native timber tree species in the dry tropic of Costa Rica</strong>  </p><p>The carbon sequestration and water use of silvopastoral systems with native timber tree species in the dry tropics were estimated. It was used an experimental design of randomly complete blocks with split plots, where grasses (<em>Brachiaria brizantha </em>and <em>Hyparrhenia rufa</em>) were the main plots and timber species (<em>Dalbergia retusa</em>, <em>Dyphisa robinioides </em>y <em>Pithecellobium saman</em>) were the subplots. The total C in aboveground biomass (grasses and trees), belowground C (fine roots and soil) and tree transpiration, using sapflow approach in 18 individuals (three repetitions per tree species per grass) were evaluated. The highest C storage in aboveground biomass was found in <em>D. robinoides </em>with 4.4 t C/ha; in C in grass was found in <em>B. brizantha </em>with <em>P. saman </em>(5.8 t C/ ha). The highest C accumulation in fine roots (d &lt; 2 mm) was found in the 20 cm of top soil. Tree growing with con <em>B. brizantha </em>presented the highest C in roots (1.1 t C/ ha); whereas the highest C in grass fine roots was located in <em>B. brizantha </em>with <em>D. robinioides </em>(1.5 t C/ha). Around 55% of soil C was in first 20 cm of soil. The highest and lowest tree transpiration was presented in <em>D. robinioides </em>and <em>P. saman</em>, respectively (1.5 vs 0.3 mm/day). The evaluated silvopastoral systems are promissory due their high C sequestration and the use of timber tree species with high water use efficiency. </p>
