Ecological and Socioeconomic Vulnerability and Opportunities Assessment (ESVOA), Tenmaru, Malekula

Abstract

The objective of an Ecosystem and Socio-economic Resilience Analysis and Mapping (ESRAM) process is to generate a robust planning baseline to inform the identification of ecosystem-based adaptation (EbA) options for strengthening the socio-ecological resilience of communities to the impacts of climate change and other direct anthropogenic impacts. The purpose of this report is to provide a comprehensive overview of Phase 2a and 2b activities that contribute towards the Integrated Ecosystem Management Plan for Tenmaru (on Malekula Island), with other reports providing similar overviews for the communities of Laone (Pentecost Island) and Southwest Bay and Wiawi (on Malekula Island) (see Figure 1). As such this report provides a: 1. Synthesis of data and lines of evidence for Tenmaru extracted from the main report. 2. Detailed options assessments specific to Tenmaru. 3. Implementation considerations. Each report contains a more detailed assessment of the recommended EbA projects from the second phase report. The assessment uses a hybrid combination of cost-benefit analysis (CBA) and multi-criteria assessment (MCA) to rank each of the recommended EbA projects, in terms of priority for implementation. Each project has been costed to an appropriate scale for each of the communities, therefore the cost-benefit analyses are subtly different for each community. Each report also contains a sensitivity analysis, which assesses whether changes to key assumptions alters project ranking. Each report also makes recommendations on appropriate stakeholder engagement to ground-truth the assumptions in each of the EbA projects and to design an implementation plan. Note that this report contains key background information and definitions from the Phase 2 report, so that it may act as a stand-alone document for the relevant community. Appendices provide data from the data collection activities (household survey and go-along survey) conducted during Phase 2.
