Characterization and Classification of Agricultural Production Systems in the Galapagos Islands (Ecuador)

摘要

The low level of agricultural productivity within the production systems in the insular region of Galapagos is caused by the lack of sustainable technologies accordingly to the insular conservation regime. As a consequence, producers face low productivity and economic losses, which result in low levels of incomes and hasten the change from agricultural to tourist activities. With consequent abandonment of productive lands, the presence of invasive species and pathogens has become a growing threat to the biodiversity of the Galapagos National Park. For this reason, it is necessary to generate and disseminate technologies adapted to the prevalent production systems in the islands. Primary data were collected through face-to-face surveys in a sample of 208 producers from 4 islands during the period from July to November 2018. Multivariate analyses (principal components and cluster) were applied to characterize and classify typical agricultural production systems. The results show three types of systems, differentiated mainly by the technology used in the management of agricultural production, that influence the yields of crops and of animal products such as beef and milk, which cannot satisfy the demand for food on the islands, which has created the dependence on imports to cover the production gap. The definition of the types of agricultural production systems can help in identifying sustainable production alternatives that integrate local social and environmental needs. This is one of the very few technical descriptions of farms on the islands and should be used by policymakers to plan interventions.
