1. Impact of Climate Change on The Nile Delta Region Adaptation Planning: An Early Warning Analysis Prof. Mohamed El Raey University of Alexandria Alexandria, Egypt 6/9/20151Prof. El Raey

2. Outline Recent evidences of climatic changes have prompt worldwide action for mitigation of greenhouse gas emissions. However, it was well recognized that mitigation measures are not enough and that proactive adaptation is necessary for all sectors of development. 1.Vulnerabilities of various sectors of development in the Nile delta region to potential impacts with special reference to coastal zone are discussed 2.The analogy of with disaster accidents and the need for proper utilization of the early warning is necessary 3.An early warning monitoring system for proper assessment and decision support in the face of widespread evidence of climate impacts is necessary for proper identification of hot spots and disaster reduction planning. Policies for long term adaptations and capacity building needs in Egypt are investigated 6/9/2015Prof. El Raey2

5. Contribution and Impacts of Egypt 1.Egypt contributes about 0.6% of world greenhouse gases and has signed Kyoto Protocol and has adopted cleaner technology mechanisms (CDM) for development 2.Impacts on water resources due to changes of precipitation rates, transfer through River Nile and increasing consumption rates 3.Impacts on agriculture production due to changes of agricultural zones and impacts of increasing heat waves 4.Impacts on coastal zone due to sea level rise, salt water intrusion and higher order impacts on water, agriculture and all other sectors 5.Impacts on economics and health due to increase of dust storms intensities and frequencies 6.Impacts on all other sectors of development which lead to increasing unemployment rates, increasing poverty and migration of unemployed population 6/9/20155Prof. El Raey

6. Stern Report The scientific evidence is now overwhelming: climate change presents very serious global risks, and it demands an urgent global response. Climate change presents a unique challenge for economics: it is the greatest and widest-ranging market failure ever seen. From all of these perspectives, the evidence gathered by the Review leads to a simple conclusion: the benefits of strong, early action considerably outweigh the costs. The impacts of climate change are not evenly distributed - the poorest countries and people will suffer earliest and most. And if and when the damages appear it will be too late to reverse the process. Thus we are forced to look a long way ahead. 6/9/20156Prof. El Raey

21. Socioeconomic Impacts on Alexandria City 1.Quantitative estimation of approximate loss due to inundation for three scenarios of SLR has been estimated in case of no action. 2.The most vulnerable sectors are the population, services and industry. Losses may reach above 60 % of these sectors for a SLR of 50 cm. 3.The order of socioeconomic losses for each sector may be different, however, again the potential losses are very high and may reach loss of 195,000 jobs in Alexandria only by the middle of this century. Over a million of low income people have to move away from these low land areas. 4.Losses in other vulnerable economic centers should also be estimated. Cultural and world heritage losses are unaccounted for. 5.Indirect economic and health losses due to salt water intrusion, soil salinization and loss of land productivity are still to be assessed. 6/9/201521Prof. El Raey

Global Sudden fall of ice masses in the polar region may cause sudden sea level rise Increasing rates and frequencies of extreme events of sand storms, and marine storms Local Flooding of low land area south east of Alexandria and/or south of Port Said Flash floods, Tsunamis, marine and heat waves over highly populated areas 6/9/2015Prof. El Raey26
