More Stable Productivity of Semi Natural Grasslands than Sown Pastures in a Seasonally Dry Climate
(2013-06-11)
In the Neotropics the predominant pathway to intensify productivity is generally thought to be to convert grasslands to sown pastures, mostly in monoculture. This article examines how above-ground net primary productivity ...
Comparative attractiveness of floral fragrance oils of "RIM" and "Catongo" cultivars of cacao (Theobroma cacao L.) to Diptera in a Costa Rican cacao plantation
(IICA, San José (Costa Rica), 1989-04)
En un terreno de cacao "Matina" abandonado de Costa Rica se hicieron pruebas durante la temporada de lluvias para comparar la atracción de tres concentraciones progresivas (100 ppm, 10 ppm, 1 ppm) de las esencias de las ...

Mapping climate change adaptive capacity and vulnerability of smallholder agricultural livelihoods in Central America: ranking and descriptive approaches to support adaptation strategies
(Springer, 2016)
Climate change is one of the main threats to rural livelihoods in Central America, especially for small and medium-sized farmers. Climate change vulnerability assessment (CCVA) integrates biophysical and socioeconomic ...
Climatology-based regional modelling of potential vegetation and average annual long-term runoff for Mesoamerica
(2010)
Mean annual cycles of runoff, evapotranspiration,
leaf area index (LAI) and potential vegetation were
modelled for Mesoamerica using the SVAT model MAPSS
with different climatology datasets. We calibrated and validated
the ...
Biomass of timber species in Central American secondary forests: Towards climate change mitigation through sustainable timber harvesting
(Elsevier, Ámsterdam (Países Bajos), 2021-06)
Sustainable management of secondary forests for timber production offers the opportunity to combine nature-based climate change mitigation with direct improvement of human livelihoods in the tropics, but this dual potential ...
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 ...
