Adaptação às mudanças climáticas em pequenos hidrossistemas: o caso do Hidrossistema de Cruzeta

Abstract

This study proposes a methodological framework for assessing the impact of climate change on small hydrosystems, presenting a case study, able to clarify adaptation strategies for human societies that undergo or may undergo similar situations. The results from the assessment of climate for Cruzeta hydrosystem, located in the state of Rio Grande do Norte, demonstrate the possibility of future scenarios drier than today, with 90% to 80% reduction in warranties. This fact shows that hydrosystems to increase their resilience need to have adaptation strategies, flexible institutional arrangements, conflict management and provision of infrastructure.
