Even with global emissions of greenhouse gases drastically reduced in the coming years, the global annual average temperature is expected to be 2°C above pre-industrial levels by 2050. A 2°C warmer world will experience more intense rainfall and more frequent and more intense droughts, floods, heat waves, and other extreme weather events. Households, communities, and planners need to put in place measures and initiatives that “reduce the vulnerability of natural and human systems against actual and expected climate change effects” (IPCC 2007). Without such adaptation, development progress will be threatened—perhaps even reversed
The Economics of Adaptation to Climate Change (EACC) study was prepared by the World Bank with the objective of estimating adaptation costs for developing countries and to help decision makers to understand and assess the climate change risks and design better strategies to adapt to climate change. This paper applies a methodology to analyse adaptation and mitigation options by taking the following four steps: picking a baseline, choosing climate change projections, predicting impacts and identifying adaptation alternatives and costing.
