Comparative Analysis of Water Efficiency in Irrigation Systems for Açaí Cultivation in the Amazon
Abstract
This study aims to comparatively analyze water efficiency in irrigation systems for açaí cultivation in the Amazonian municipalities of Abaetetuba and Igarapé-Miri, evaluating the influence of water vulnerability on productivity. Based on the concepts of development as freedom, governance of the commons, and stakeholder management, it employs a mixed-methods approach, combining qualitative and quantitative analysis with secondary data and performance indicators. The research shows that Igarapé-Miri presents greater water efficiency and productivity, but faces greater aquifer vulnerability, highlighting the need for participatory governance for water sustainability. The results generate practical implications for public policies and local management, reinforcing the importance of social contracts, community monitoring, and incentives for artificial recharge. Limitations are related to geographical restrictions and the absence of long historical series. The study contributes with a diagnosis that integrates environmental indicators with production models, broadening the understanding of sustainability in complex hydrological contexts in the Amazon.
