“…We selected dams 2 and 31 as the most unsuitable locations because they took up lots of space in private properties. In conclusion, the most suitable dams' locations of 5 m were 15,16,17,19,20,27,28,29,30, shown as blue in Figure 11, while the best dams location at 2.5 m height were 6,8,15,16,17,19,20,23,24,27,28,29,30,33,35 shown as yellow.…”

“…small dams at 5 m, dam15, 16,17,19,20,27,28,29,30 did not affect the surrounding residential buildings, with a total of 16,809 m 3 water retained. Among them, dams 6,8,23,25 had a slight impact on the buildings concerned as moderately suitable areas.…”

“…Honiara currently has an estimated population of 92,344 [4], and the up-to-date information indicates that approximately 86% of Honiara's population lives in rural areas, with only 50-70% having access to water supply [28]. In the next ten years, as the number of residents grows, the water demand will also rise by 40% [4], and inhabitants who are not living in a formal settlement will struggle to receive water services [29].…”

“…Finally, we added the Building Footprint layer to compare with each inundation zone to choose the proper sites that did not influence the surrounding buildings. By comparing the location of nearby residential areas (Figure 9), it was found that small dams at 5 m, dam15, 16,17,19,20,27,28,29,30 did not affect the surrounding residential buildings, with a total of 16,809 m 3 water retained. Among them, dams 6,8,23,25 had a slight impact on the buildings concerned as moderately suitable areas.…”

Suitability Assessment of Small Dams’ Location as Nature-Based Solutions to Reduce Flood Risk in Mataniko Catchment, Honiara, Solomon Islands

As global temperatures rise, flooding and storm surges caused by extreme weather threaten people’s safety and nations’ development. Nature-based Solutions (NBS) are practical actions to support resilience to reduce flood risk and are applied in many countries. As the NBS approach mentions, small check dams made of gabion and wood can retain runoff and temporarily create detention basins to reduce the magnitude of floods and provide additional water resources. However, previous dam suitability research emphasized the criteria selection and decision method evolution, which costs time on the complex calculation and does not fit the NBS small dams. This research aims to optimize the site selection workflow of small dams in vulnerable informal settlements by utilizing Remote Sensing (RS), Geographic Information Systems (GIS), and Multi-Criteria Evaluation (MCE). Several thematic layers, such as land use, river density, building distance, vegetation cover index, slope, and elevation factors, were chosen to identify the suitable area in Mataniko catchment, Honiara. More importantly, it provides a more efficient model builder that can be replicated in ArcGIS 10.8, which contributes to visualizing scenarios of the inundation area of small dams at different heights. As a result, this study tested up to 35 potential small dams with 2.5 and 5 m wall height in the flood-prone Vara Creek and selected nine small dams with 5 m height and 15 small dams at 2.5 m as the best locations according to the volume and area. Overall, it is an efficient tool for designers to communicate with different stakeholders and applies to other developing countries facing frequent floods. Moreover, it provides a prototype and evidence of NBS action to address the flood issue.

“…This highly participatory programme of action research, led by an Australian university since 2014, has helped identify key vulnerabilities and priority resilience actions at community, ward, and city levels; and provided the evidence base for a new UNFCCC Adaptation Fund project called 'Climate Resilient Honiara', administered by UN-Habitat. For a review of this journey, see reference [7].…”

The capital cities of the South Pacific are experiencing rapid urbanisation pressures as increasing numbers of people migrate to the primary cities either in search of employment and greater access to healthcare and education, or as a consequence of environmental ‘push’ factors. However, the limited capacity of municipal Governments to respond to the scale and pace of change is leading to a growth of informal settlements in peri-urban locations. Factors of exposure, sensitivity, and adaptive capacity combine to make these informal settlements the most vulnerable areas to natural hazards. In response to this critical urban resilience agenda, this paper looks at how participatory action research is providing inter-disciplinary scientific support for the implementation of urban resilience and climate actions in Honiara, Solomon Islands. Adaptation measures involve a combination of hard and soft actions; as well as activities designed to strengthen local capacity to respond to contemporary resilience challenges. Addressing the adaptive capacity component, this paper also highlights the opportunities for Australian universities to integrate teaching and learning with action research to achieve a substantive real-world impact in the Pacific region, as well as illustrating the capacity strengthening benefits that can be achieved through sustained engagement and collaborative partnerships with local organisations.
