VAZQUEZ-MORENO, Luis L.. Resilience of agricultural production systems exposed to hurricane Irma in Cuba. Pastos y Forrajes [online]. 2021, vol.44 Epub 10-Ago-2021. ISSN 2078-8452.
Objective:
To evaluate the resilience of production systems exposed to hurricane Irma in territories of Cuba.
Materials and Methods:
The general index of resilience to tropical cyclones (GIRtc) was determined, which was contrasted with the coefficient of agroecological design and management (AdmC). They were both complemented with the evaluation of the sensitivity of productive species and the vulnerability of the cultivation and animal husbandry systems.
Results:
The production systems were grouped in three clusters, with higher contribution for these groupings by their resistance capacity during the event and their permanent transformability, as well as by the design and management of the production system and structure of agrobiodiversity. The sensitivity of the cultivated species showed certain differences for the plant types in the following order: annual and temporary agricultural crops > semi-permanent crops > fruit trees > permanent herbaceous plants. The vulnerability of the cropping and animal husbandry systems in each studied production system was lower for the systems of cluster III, in which 62,5 % of the crops remained. This contrasts with cluster I, in which 38,5 % of the production was rescued during the process; while in the systems of cluster II 2,7 % could be maintained.
Conclusion:
The production systems that adopted agroecology expressed different capacities of resilience, which is related to the traits contributed by the design and management of the existing cropping and animal husbandry systems, as well as the rest of the production system.
