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.
This vulnerability and risk assessment aims to provide a science-based cornerstone for the formulation of more responsive and adaptive local development. This study adapts the methodology used by the Ministry of Environment Climate Change Adaptation and Risk Assessment (KRAPI) in 2012. The assessment was conducted through a series of workshops as a consultation forum for many local stakeholders and experts.
The sectors selected in this assessment have similar characteristics, challenges and opportunities in the four cities and districts as one landscape. The selected sectors are not only strategic for each city/district but are also interrelated with dependency between the cities/ districts. Please note sectors already covered in KRAPI are not analyzed in this assessment. Based on that logical framework, this assessment focuses on horticulture agriculture, animal husbandry, infrastructure, and plantations. The assessment started with reading climate and disaster historic data, climate projection, estimating climate change impacts, choosing strategic sectors for adaptation actions, analyzing hazards, analyzing vulnerability, analyzing risks, conducting synthesis of hazards and risks, and prioritizing adaptation actions.
The approach to analyze hazards, vulnerability, and risks was conducted through spatial data processing and linked to indicators agreed in the workshops. If there are any limitation on availability and access to data, then there are adjustments using representative substitute indicators.
The main results of the assessment are maps on comparison of hazards, vulnerability, and risks divided in three categories. Analysis maps were developed not only based on sectors, but also overalyed for all sectors. With doing so, this assessment is expected to give a holistic and bigger picture at the landscape level to understand hazard, vulnerability, and risks of climate change. This assessment forms the basis for development of adaptation strategies and its mainstreaming in local development plan and ensuring this takes place is an important next step.
