Mombasa is Kenya’s second Fellow on Climate Change in the Energy and Water largest city and has more than 700,000 inhabitants. It is the largest seaport in East Security Programme Africa, serving not only Kenya but also many landlocked countries and the north at the African Centre of Tanzania.

The latest report from the Intergovernmental Panel on Climate Change (IPCC) identifi es various climate change-related health impacts, including altered distribution of some infectious diseases and disease vectors. According to the report, projected trends in climate change-related exposures will increase malnutrition and consequent disorders; increase the number of people suffering from death, disease and injury from heat waves, fl oods, storms, fi res and droughts; and will continue to change the range of some infectious disease vectors. The burden of diarrhoeal diseases will increase and the geographical range of malaria will expand in some nations and contract in others, and transmis- sion seasons will alter.(2) This could negatively affect the productivity of 2.

The city is also a popular tourist destination due to the presence of various terrestrial and marine-based ecological attractions, including warm weather, sandy beaches, 232 CLIMATE CHANGE AND COASTAL CITIES and historical and cultural monuments.
