Adaptation to Climate Change in Coffee Production Systems in Tolima
Publicação on-line; 43 ref.; 5 illus.; Summary (En)
ABSTRACT
It was estimated the climate change adaptation of the main coffee production systems in
Líbano, Tolima, Colombia, using diversity indicators. Three production systems were selected:
agroforestry systems (AFS) with Cordia alliodora, AFS with plantain and in monoculture,
with four replications, locating five sampling units to collect and identify the ant genera as
diversity and adaptation indicators. The richness index of Margalef detected between systems
(1.3 vs 0.6 vs 0.6 for AFS with C. alliodora, monoculure and AFS with plantain, respectively). The
genera Cephalotes, Dorymyrmex, Hypoponera, Pachycondyla, Octostruma and Proceratium, which
require abundant biomass and litter, were registered just in AFS with C. alliodora, coinciding
with the depth of this layer. The AFS with C. alliodora present advantages due they improve
conditions for the conservation of several groups of ants, which are indicators of diversity and
climate change adaptation.
Keywords: diversity, litter, ants, agroforestry systems.
