Genetic diversity and spatial structure in a new distinct Theobroma cacao L. population in Bolivia
(2015)Cacao (Theobroma cacao L.) is an important economic crop in the Bolivian Amazon. Bolivian farmers both cultivate cacao, and extract fruits from wild stands in the Beni River region and in valleys of the Andes foothills. ... -
Información hidrológica, primer paso para diseñar una política local de pago por servicios ambientales
(2015)Los recursos hidrológicos tienen significativa importancia en países con problemas de escasez de agua, parte de los cuales se atribuyen a la inexistencia de una relación entre los proveedores de servicios ambientales y de ... -
Influence of topographic and edaphic factors on vulnerability to soil degradation due to cattle grazing in humid tropical mountains in northern Honduras
(2015-01-22)Low altitude humid tropical mountains in Central America have experienced a process of livestock expansion during recent decades. However, the use of sloping areas for cattle grazingmay lead to significant soil degradation and ... -
Payment for Ecosystem Services: The roles of positive and information sharing in stimulating adoption of silvopastoral conservation practices
(2015-01-22)Payment for Ecosystem Services (PES) applied to agricultural systems, such as tropical rangelands, seeks to provide multiple services while sustaining food production. However, there is considerable debate regarding the ... -
Agricultural intensification alters bat assemblage composition and abundance in a dynamic Neotropical landscape
(2016)The recent trend of agricultural intensification in tropical landscapes poses a new threat to biodiversity conservation. Conversion of previously heterogeneous agricultural landscapes to intensive plantation agriculture ... -
What information do policy makers need to develop climate adaptation plans for mallholder farmers? : the case of Central America and Mexico
(Springer, 2016)Scientific and technical information can increase the ability of policy makers to make strategic decisions. However, climate change policy is often formulated without significant input from science. We examine whether ... -
Old-growth neotropical forests are shifting in species and trait composition
(2016)Tropical forests have long been thought to be in stable state, but recent insights indicate that global change is leading to shifts in forest dynamics and species composition. These shifts may be driven by environmental ... -
El enfoque de medios de vida combinado con la indagación apreciativa para analizar la dinámica de la cobertura arbórea en fincas privadas: el caso de Costa Rica
(2016)Se propone mostrar que es factible estudiar la complejidad de la dinámica arbórea en fincas privadas en tres zonas agrícolas de Costa Rica. Con este fin, se aplicó la combinación de enfoques de capitales de la comunidad y ... -
Human pressure on water quality and water yield in the upper Grijalva river basin in the Mexico-Guatemala border
(ELSEVIER, 2016)Forest ecosystems are major providers of high quality water and contribute to maintain a better distribution of base flows during the year. However, these environmental services have been adversely affected by human pressure ... -
Spillovers from targeting of incentives: Exploring responses to being excluded.
(Elsevier, Ámsterdam (Países Bajos), 2017)A growing set of policies involve transfers conditioned upon socially desired actions, such as attending school or conserving forest. However, given a desire to maximize the impact of limited funds by avoiding transfers ... -
Leadership for moving the climate change adaptation agenda from planning to action
(Elsevier, Ámsterdam (Países Bajos), 2017)An increasing number of initiatives for adaptation to climate change are occurring at multiple scales and decision focuses (e.g., impact assessment, policy design, technology development, planning management and implementation ... -
A global map of mangrove forest soil carbon at 30m spatial resolution
(2018)With the growing recognition that effective action on climate change will require a combination of emissions reductions and carbon sequestration, protecting, enhancing and restoring natural carbon sinks have become ... -
Population genomic analyses of the chocolate tree, Theobroma cacao L., provide insights into its domestication process
(2018)Domestication has had a strong impact on the development of modern societies. We sequenced 200 genomes of the chocolate plant Theobroma cacao L. to show for the first time to our knowledge that a single population, the ... -
Los agroecosistemas cafetaleros modernos y su relación con la conservación de mariposas en paisajes fragmentados
(2018)Land use change by the intensification of agriculture contributes to tropical forest fragmentation and biodiversity loss. In this sense, in comparison with traditional agroforestry systems (AFS), modern AFS are considered ... -
The impacts of a capacity-building workshop in a randomized adaptation project
(CATIE, Turrialba (Costa Rica), 2019)Encouraging adaptation to climate change is fundamentally about encouraging changes in human behaviour. To promote these changes, governments, non-profits and multilateral institutions have invested in a range of ... -
Forecast models of coffee leaf rust symptoms and signs based on identified microclimatic combinations in coffee-based agroforestry systems in Costa Rica
(Elsevier, Ámsterdam (Países Bajos), 2019)Coffee leaf rust is a polycyclic disease that causes severe epidemics impacting yield over several years. For this reason, since the 1960s, more than 20 models have been developed to predict different indicators of the ... -
Deforestation processes in the livestock territory of La Vía Láctea, Matagalpa, Nicaragua
(2019)Land-use change is considered one of the main causes of environmental degradation. Thus, its analysis will allow stakeholders to make reasonable decisions for land management. The objective of the present study was ...
