Abstract
The research was jointly undertaken with government agencies within Madagascar and involved combining local-level climate impact modelling with economic analysis of the costs and benefits of adaptation in order to manage risks and promote climate change resilient infrastructure and livelihoods in the coastal zone. Specifically, the research estimated the cost and potential of roof-top rain water harvesting to supplement the water supply for the tourism sector in Nosy Be, Madagascar in order to reduce costs and manage stresses on the island's fresh water reservoir. The project was one of two pilot activities completed for the Indian Ocean Commission over the period 2012-2014 as part of the ISLANDS project to accelerate the implementation of the United Nations sustainable development strategy for small island states. The research method involved: 1. Determining the current water use patterns on Nosy Be and the allocation of water between tourism, residential, and agricultural uses. 2. Conducting an inventory of hotel and tourism operations and estimating current water use patterns. 3. Developing socio-economic scenarios to estimate increases in water demand over coming decades due to increased population growth, agricultural intensification, and the expansion of the tourism industry. 4. Developing profiles of current climate conditions and future climate change scenarios to model the changes in precipitation, and hence the availability of water for both reservoir recharge and roof-top rainwater harvesting. 5. Evaluating the performance of different roof and rain tank combinations using historic and projected precipitation data and water demand estimates. 6. Using economic cost-benefit analysis and multi-criteria decision making tools to identify water supply options that provide the best value for money and are consistent with sustainability criteria (social, environmental and economic). 7. Using the findings to develop strategies that mainstream climate related risk reduction and adaptation into water use planning at the local level.
