Abstract
Existing frameworks of community-based early warning systems (CBEWS) lack focus on its actual implementation. Furthermore, they do not describe how a top-down early warning system (EWS) can be transformed into a CBEWS. Hence, to support the establishment of a community-based early warning system for deep-seated landslides (CBEWS-L), this study aimed to assess the capacities and vulnerabilities of five barangays in the Philippines. The CBEWS-L to be established is envisioned to be information and communication technology (ICT)-based. An ICT4D perspective was therefore taken in conducting this participatory study. Stakeholder mapping, focus group discussions and key informant interviews were used to gather data. Validation was also done through triangulation and post-analysis consultations. The results showed that there are varying sets of capacities and vulnerabilities existing in each community. Moreover, ICT capacities are lacking and are outnumbered by vulnerabilities. Yet, site-specific action points to enhance capacities and resolve vulnerabilities were determined. Still, overall strategies were not uncovered. Furthermore, compounding the capacities and vulnerabilities in each site are indirect factors which, if examined thoroughly, may lead to more complex socio-political issues. It is therefore recommended that in establishing a CBEWS, a comprehensive community risk assessment is first conducted to exhaust all possible action points that can be used in formulating site-specific strategies. Moreover, development of technological solutions must be modular to allow flexibility in accommodating complex community capacities and vulnerabilities.Keywords: Early warning systems; community risk assessment; participatory research; information and communication technology or development; community-based disaster risk reduction and management.
Highlights
Deep-seated landslides are characterised by a slip surface of at least 3 m (Kaunda 2010)
Variations in the set of capacities and vulnerabilities for each site led to differences in identified action points
We argued that establishing a CBEWS-L necessarily includes the four PEWS elements (UNISDR 2005)
Summary
Deep-seated landslides are characterised by a slip surface of at least 3 m (Kaunda 2010) Their occurrences are typically related to about 30–90 days of constant rainfall, as opposed to shallow landslides which are often related to 1–15 days of rainfall (Zêzere, Trigo & Trigo 2005). Deep-seated landslides are said to pose larger risks, as they are more likely to cause disastrous debris flows and landslide dams (Dou et al 2015). Such was the case of the 2006 Southern Leyte Landslide that recorded 139 casualties (Catane et al 2007). For hazard information to be actionable, it should be relayed to the community as warnings to prevent imminent danger (International Federation of Red Cross and Red Crescent Societies 2012)
