The objective of an Integrated Ecosystem Management Plan 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 ESRAM for Wiawi (on Malekula Island), with other reports providing similar overviews for the communities of Laone (Pentecost Island) and Tenmaru and South West Bay (on Malekula Island) (see Figure 1). As such this report provides a: 1. Synthesis of data and lines of evidence for Wiawi extracted from the main report. 2. Detailed options assessments specific to Wiawi. 3. Implementation considerations.
