Integrated vulnerability assessment of water-energy-food security nexus in Waras-Lalo watershed, Bicol River, Basin, Philippines
2018
Peña-Rodriguez, M.G.A.
The usual vulnerability assessment is often sectoral and hazard-specific. With the nexus approach on water, energy and food (WEF), it is recognized that these three sectors have interactions and synergies and tradeoffs in their activities. Security has five dimensions, namely: availability, accessibility, affordability, accessibility, quality and sustainability. This study involved developing and implementing an integrated vulnerability assessment (IVA) methodology and framework of WEF security nexus applied to a watershed. The framework considered the watershed with three sub-systems of ecological, energy and food interacting with water as the common element. The same concept of vulnerability assessment was used for IVA as a function of exposure, sensitivity and adaptive capacity. IVA was operationalized by identifying variables or parameters pertaining to relationships among WEF and inclusion of sectoral variables related to the various dimensions of security. Based on the study, IVA of WEF nexus is a more holistic approach in assessing vulnerability. IVA account for the relationships among the sectors, in contrast to the sectoral approach. Using the combined climate risks due to different hazards (intense typhoons, erratic rainfall, severe drought, and temperature rise) gives a broader coverage unlike the hazard-specific approach. Parameters used were applicable for IVA of the watershed area. Additional relevant variables can be included if data are available.
