This manual may be used by stakeholders who can benefit from information on data collection methods on aspects of mangrove monitoring and evaluation. This manual has been separated by areas of interest, namely Components (i) Socio-economic (ii) Ecological and (ii) Physical data collection methodologies. It also includes a section on Economic Valuation methods under ‘Further Monitoring’. The manual also indicates how data collected on these different components can be combined to create a holistic approach to investigating coastal ecosystems, flood risk and damage to life and livelihood as well as mitigation using nature based solutions (i.e. mangroves).
