Abstract
ABSTRACT It was estimated the climate change adaptation of the main coffee production systems in Libano, 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.
Highlights
The current climate change in the planet is accelerated by anthropic activity, mostly given by the increase in the emission of greenhouse gases (GHG) caused by land use, deforestation, use of fossil fuels, cement production and the agricultural production (Intergovernmental Panel on Climate Change [IPCC], 2002)
Adaptation to climate change in coffee production systems was estimated as the capacity of studied systems to shelter ant diversity, considered as a taxonomic group indicator of the system diversity
The Myrmicinae subfamily has a high representativeness in coffee landscapes in the Colombian Andean area, in Valle del Cauca, Antioquia and Santander (Clavijo et al, 2008)
Summary
The current climate change in the planet is accelerated by anthropic activity, mostly given by the increase in the emission of greenhouse gases (GHG) caused by land use, deforestation, use of fossil fuels, cement production and the agricultural production (Intergovernmental Panel on Climate Change [IPCC], 2002) This world-wide phenomenon notoriously affects the biological diversity of ecosystems due to the loss of habitats and landscape fragmentation (Uribe, 2015). Some measurements must be implemented aiming to give a sustainable management to the planet considering the adaptation needs of the organisms to the climate change (MAGRAMA, 2016) Preserve ecosystems, their biodiversity and ecosystem services is a full strategy that helps adapting to climate change (EEM, 2003). This strategy generates social and economic benefits, and contributes to preserve the diversity of plant and animal species (UICN, 2012)
