Towards liveable volcanic cities: A look at the governance of lahars in Yogyakarta, Indonesia, and Latacunga, Ecuador

The physical and governance challenges posed by urban planning and integrated water resources management (IWRM) are gaining momentum worldwide. Yet, the governance of Volcanic River Basins (VRB) remains vastly unexplored. There are at least 500 active volcanoes worldwide, with 600 million people living near them. Through a multiple-case study methodology, we aim to contribute to the understanding of how lahar risks management is being conducted in two distinct urbanized volcanic river basins: Yogyakarta in Indonesia, and Latacunga in Ecuador. Both are located in the “ring of fire” with recent eruption threats in the last decade. The two cases were conducted independently, both triangulated by international and national literature reviews, policy analysis, and in-depth interviews. The Indonesian case study focuses on the governance intricacies for water and disaster management after 2010 eruption during pre, onset, and post-eruption. The Ecuadorian case study looks at risk governance from the perspective of households after a volcanic eruption in 2015, highlighting how bottom-up risk management strategies interact with top-down governance policies. Based on both case studies, a synthesis framework for Volcanic River Basin Management (VRBM) is formulated. This framework can be used as the way forward to analyze disaster and resources management in urbanized volcanic areas.
