Cooling capacity and condensation of atmospheric humidity of shade trees in coffee plantations from the Pluma Hidalgo region, Oaxaca

The cooling capacity of the vegetation is usually faster than the environment in a forest ecosystem, building up dew on the leaves of the trees that are in the tree canopy; depending on the species, they usually register different temperatures in the stem, in the leaves and branches.

Sumario:The cooling capacity of the vegetation is usually faster than the environment in a forest ecosystem, building up dew on the leaves of the trees that are in the tree canopy; depending on the species, they usually register different temperatures in the stem, in the leaves and branches. In this way, the temperatures of the main shade trees in coffee plantations of Pluma Hidalgo, Oaxaca, were compared in order to obtain which ones cool the fastest and, therefore, condense more atmospheric humidity. The temperatures of the environment, the dew point and stems and leaves of some main tree species were recorded for 24 hours to find the relationship between the cooling of the trees and the ambient temperature. To perform the data analysis, the Generalized Linear Model (GLM) was used with a gamma distribution, by using the Tidyverse, Broom and MuMIn packages, and the Software R version 4.1.2 and RStudio version 2021.09.2+382. As a result, it was found that the palo mujer (Alchornea latifolia Sw.) is the tree that reaches the lowest temperatures at the time the ambient temperature was lowest, which indicates that this tree has the greatest cooling capacity, therefore, in a reforestation project, its use is recommended to develop the function of condensing atmospheric humidity.
