Sustainability, Vol. 8, Pages 598: A Socio-Institutional Approach to Brighten Complexity under Agricultural Pest Invasion Conditions

This study illustrates the inherent complexity and uncertainties surrounding the Guatemalan potato moth pest on Tenerife that has affected potato crops for several decades using a Socio-Institutional methodology and a farmers' focus group. It focuses on detecting major socioeconomic and environmental impacts caused by the pest. It identifies the stakeholders and historical decisions involved as well as systemic uncertainties. This methodology generates socially robust knowledge and introduces new variables into future decision-making processes. The results show that the efforts made so far to control the pest, based on technical and scientific knowledge, have not been commensurate with the enormous complexity of the issue. Novel alternatives to eliminate the plague and new recommendations have emerged after the application of the methodology. These alternatives and recommendations are related to breaking the reproduction cycle of the moth; promoting agro-ecological strategies and participatory processes; and dealing with uncertainties such as climate change or loss of agro-biodiversity on the island.
