South Sulawesi province has 46.717,48 km2 area with population 8,2 million in 2012, and population density 175,84 people/km2 that spread in 24 Regency/City (www.sulselprov.go.id). Based on data from BNPB 2012, some regency in South Sulawesi have hazard potential.
Risk Assessment workshop in South Sulawesi has been compiled by BNPB on 2011. However based suggestion from other institutes in South Sulawesi, risk assessment document need reviewed and developed suitable with hazard condition in South Sulawesi. Therefore, risk assessment held this year to complete risk assessment document, so South Sulawesi has risk assessment document with complete the data and update.
Risk Assessment workshop in South Sulawesi has six priority hazard, consists of Flood, Earthquake, Dryness, Waterspout, Fire, and Landslide. Region to be examined in the risk assessment mapping consists of Jeneberang watershed, around Tempe Lake, and Luwu Raya. The implementation field survey just doing in Jeneberang watershed because limited time.
The risk assessment activities have some stages, such as schema in the bottom, we will explain about Workshop 1.
On April 20th-22th 2015, Humanitarian OpenStreetMap, RNV and CDSP held disaster risk assessment workshop and training in South Sulawesi. There are 40 participants that attend the training and workshop from BPBD South Sulawesi, representation from institutes in South Sulawesi province, lecturers, and students. Training material consists of : (1) Concepts and methodology risk assessment workshop, (2) formulation data and parameters, (3) Making the scoring map vulnerabilities and capacities of village potential data using Excel, and (4) Join village potential data summary tables districts with administrative boundaries using QGIS.
The first day of the workshop 1, participants learn about the concept of risk assessment document, with example of their own area, South Sulawesi district. After that participants got quick explanation about the paradigm of disaster management and concept of risk assessment document by BPBD South Sulawesi. The next session after lunch was focus group discussion. All the participants divided by 4 groups and asked to discuss to each other about specific topic for each group and then presented it in the end of the session. This session aim to improve participant’s knowledge about risk, vulnerability, capacity and hazard in their area in order to prevent and face the disaster in their own area. After they got a background of their own hazard, capacity and risk in their area, they asked to think about the steps of disaster risk assessment and what data they need in order to achieve that.
Then participants began to prepare statistical data from BPS to spreadsheet. Divided by 3 small group, each group must filter and sort data from BPS according to their task, create one spreadsheet vulnerability data and capacity data. All those data must according to indicators that they already discussed before. In the end of this day, the participants already have vector data that have capacity data inside it.
On the second day, the participants continue create vulnerability data and installation QGIS for join capasity data and vulnerability with administration regency in South Sulawesi. In the end of this day, the participants already have capasity and vulnerability maps.
In the last day, participants need to create risk map based on all the data that they already created several day before. All the participants learn how to create scoring to capacity and vulnerability data, overlay vector data and create map from that. After they create capacity, vulnerability and hazard map, they learn how to evaluate the risk. In this session facilitator explain about how to evaluate the impact of disaster in certain area in the several vital component population, infrastructure, landuse, and economy using QGIS and InaSAFE. The result from InaSAFE less satisfactory because the building in South Sulawesi has not been fully mapped. Therefore, to plan follow-up will be held using OpenStreetMap to exposure mapping. Results from the workshop I activities consists of capasity maps and vulnerability maps that will be used to stage at Workshop II.
The next activities risk assessment in South Sulawesi will be explain in Training and Exposure Mapping in South Sulawesi.
