A methodological proposal for the evaluation of farmer's adaptation to climate variability, mainly due to drought in watersheds in Central America
(2008)
The current study shows the process and the results of a methodology proposed to contribute with the issue of how to evaluate the adaptation to climate variability and future climate change. The proposed methodology consists ...
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 ...
Effect of woody and herbaceous legumes on the growth and nutrient content of two tropical grass species
(CATIE, Turrialba (Costa Rica), 1999)
Se realizó un experimento factorial (2 X 2 X 5) con dos especies de gramineas, Panicum maximum Jacq. (Var. CIAT 16061) y Brachiaria humidicola Rendle (Var. CIAT 679) en monocultivo o en asocio con Centrosema macrocarpum ...
Available soil water in a Coffea arabica-Erythrina poeppigiana, C. arabica-Eucalyptus deglupta and C. arabica monoculture plantations
(1999)
Se evaluó el agua disponible en el suelo de 0-15, 15-30, 30-45 y 45-60 cm de profundidad, en parcelas de café sin sombra y con sombra de Eucalyptus deglupta o Erythrina poeppigiana, durante la estación seca en el Valle ...

This article presents a brief review of the main environmental service functions that are provided by agroforestry systems (AFS): 1) maintenance of soil fertility/reducing erosion via organic matter inputs to the soil, N ...
Control of lateral root extension of fast-growing timber species using grasses as biological barriers
(1999)
Se investigó el potencial de cinco especies de gramíneas como barreras biológicas para reducir la competencia radicular en asociaciones agroforestales con árboles maderables de crecimiento rápido como Eucalyptus deglupta ...
Shade effects on moisture relations of agroforestry systems
(1999)
Although competition of shade trees for water with shaded crops has been a major argument in favor of the removal of shade trees in agroforestry systems, experimental results do not always confirm that shade trees increase ...
Groundwater vulnerability mapping in two watersheds affected by Yacyreta Dam in Paraguay
(2015)
Groundwater vulnerability mapping was conducted for two
intensive agriculture and urban watersheds draining to the
Yacyreta Dam in Paraguay. Two widely used overlaying
methods (GOD and DRASTIC) were applied and compared
to ...
Estimating dew duration on banana and plantain leaves from standard meteorological observations
(Elsevier (Amsterdam), 1992)
Black Sigatoka is an important fungal disease of bananas and plantains. Dew duration on the upper leaves of these plants (Leaves O and 1) is an important factor in the development of the disease. A general dew estimation ...
