The years 2015 and 2016 are listed by the World Meteorological Organization as the hottest years in the last hundred years. Extreme weather events, floods and landslides are becoming more frequent. The risks of climate change and disasters are faced by all levels of society in Brantas water shed; but the communities that will most likely feel the impact are: farmers, fishermen, and the urban poor. The impacts of climate change can reduce development outcomes, threaten food security, and increase poverty. Most of the disasters that occur in Brantas water shed are related to climate and weather (hydrometeorological disaster).
Almost all areas of Jombang Regency, Mojokerto Regency and Sidoarjo Regency are included in the Brantas River Basin (DAS). All three are in one landscape so that several strategic sectors are interconnected with each other. Combined they contributes 13.83% to the East Java GDP. Because of its geographic position, the three districts are receiving impacts from climate change and potentially worsening future disasters. Therefore, vulnerability and risk assessments need to be conducted in an integrated perspective. Likewise, problem solving needs to be done alongside administrative boundaries.
This vulnerability and climate risk assessment is intended to provide a strong, knowledge based foundation for developing climate change adaptation and regional resilience strategies. At the same time as input for regional development planning that is more adaptive to climate change.
This review adapts the methodology used by the Ministry of Environment in Climate Change Risk and Adaptation Assessment (KRAPI) 2012. The review process is conducted through a workshop that is a consultation forum with local stakeholders and experts in each field.
The chosen field in this study refers to the similarity of the three districts’ characters as a unity of the landscape. Selection of areas studied, in addition to being strategic for each district, but also because of inter-dependency and interdependency between districts. Based on the concept of thought, the field of study focused on rice farming, ruminants farming, aquaculture, clean water field and flood and landslide disaster mitigation.
The approach to threat, vulnerability and risk analysis is done through spatial data processing, referring to indicators of each component agreed upon in the workshop. If there are limitations on availability and access to data, adjustments are made by using a representative data indicator. The main outcomes of the study were the map of the distribution of threats, vulnerabilities and risks that were divided into class categories. The analytical map, besides arranged according to the field of study, is also assembled between all areas of study. Thus, it is hoped to provide an overall picture on a provincial scale to understand the threats, vulnerabilities and risks of climate change.
The systematic content of this report contains methodology, description of areas,
justification of field selection, event analysis and projected threats, vulnerability and risk analyzes of each priority field and multi-field analysis. At the end, the report includes temporary recommendations for adaptation action options for each field. Further studies and consultations are needed to detail specific strategies and action options for adaptation at specific locations.
