Nexo água-energia-alimento: concepções sobre o estado de Alagoas através do Adaptabrasil

Abstract

The Water-Energy-Food (WEF) Nexus emerges as an integrative approach, essential for understanding and managing the interdependence between water, energy, and food security. This concept is particularly relevant in the face of societal challenges, especially climate change and resource scarcity. Therefore, this study aimed to characterize the state of Alagoas in terms of the Water-Energy-Food Nexus. To achieve this, bibliographic research was conducted, which provided an understanding of the theoretical and conceptual aspects relevant to the study. Subsequently, data from the AdaptaBrasil MCTI and IBGE databases were used to characterize the municipalities and population of Alagoas separately and in an integrated manner. It was found that, in the water sector, most municipalities show favorable conditions. Approximately 43.14% of areas were classified as "Low" and 1.96% as "Very Low" regarding the impacts of drought, indicating overall water stability. In terms of food security, a balanced condition was observed, though highlighting the need for resilience strategies to address the impacts of heavy rainfall on food production and distribution. On the other hand, energy security revealed greater vulnerabilities, especially concerning accessibility, indicating that, despite a reasonably stable supply, the capacity to meet demands may be insufficient in times of crisis. The results suggest that Alagoas has favorable conditions for water and food security. However, the vulnerabilities observed in energy security and the challenges associated with periods of intense rainfall underscore the importance of public policies that promote sustainability and resilience to enable development aligned with climate change.
