Almost all of Malang City, Batu City, Malang District, and Blitar District form part of the Brantas Watershed. Those four areas are all considered one landscape, i.e. upstream Brantas, and as a result several strategic factors are interrelated. Economically, this landscape contributes 13.83% of East Java GRDP. Due to many factors, these four cities and districts are significantly impacted by climate change and disaster events with the potential for this to get worse in the future. Therefore, it was important to carry out the vulnerability and risk assessment in one integrated approach. Similarly, many of the solutions and strategies to address the risks cross administrative boundaries.
