European-African Partnership in Satellite Applications for Sustainable Development A Comprehensive Mapping of European-African Actors and Activities in the framework of the conference “Space for the African Citizen” hosted by the Belgian EU Council Presidency on 16 September Climate Change and Variability: Experience in use of Space Technology over the Greater Horn of Africa Omondi P. A. (PhD) ICPAC MAJOR AFRICAN CLIMATE CENTRES ACMAD Niamey ICPAC Nairobi SADC Gaborone IGAD CLIMATE PREDICTION AND APPLICATIONS CENTRE (ICPAC) a specialized Institution of the Intergovernmental Authority on development (IGAD) charged with the Responsibility of Coordinating all Regional Climate Risk Reduction related issues in the Greater Horn of Africa ICPAC MISSION: To provide climate information, prediction, timely early warning for applications in support of environmental management, disaster risk reduction and sustainable development in the IGAD Region Vision: To become a viable regional centre of excellence in climate risk reduction including coping with present climate extremes as well as adaptation to future climate changes for environmental management, disaster risk reduction, poverty reduction and sustainable development. OVERALL IMPLICATIONS OF CLIMATE CHANGE 6 May 2017 IRI-WMO Worksop Beijing China 19-30 October 2009 GLOBAL WARMING AND CLIMATE CHANGE • Global warming and overall climate change is now a scientific reality to be reckoned with in all countries of the world, and more particulary in Sub-Saharan Africa which has been shown to be the most vulnerable. • In its Fourth Scientific Assessment brought out in 2007, the Intergovernmental Panel on Climate Change, the IPCC said global warming is “unequivocal, as is evidenced by numerous observations around the world. CLIMATE VARIABILITY AND CLIMATE CHANGE • Climate variability is what we see more clearly in terms of the higher temperatures we are experiencing ,or changes in rainfall characteristics from season to season, and from year to year. • We often realise we are dealing with change too late. WHAT THE IPCC SAYS ABOUT CLIMATE CHANGE • “Global climate change will have a wide range of impacts, and overall negative health impacts will outweigh positive impacts. • Changes in frequencies of heat and colds will be accompanied by an increase in morbidity and mortality; • Other impacts will come from changes in the frequency of floods and droughts; Perspectives The Problem Climate change and variability are real – Extreme climate events are more frequent and devastating Increasingly, there are evidence showing that climate, human and animal health are integrally linked in Africa through many different associations –(Zoonoses, malaria epidemics, RVF, Yellow fever ,respiratory disorders & other emerging and re-emerging diseases) Many vector borne diseases are sensitive to changes in meteorological parameters such as- rainfall, temperature, and humidity There are other climate change impacts that have a negative direct bearing on human health – Droughts, floods, food deficiency , Climate change will continue to influence the distribution and occurrence of communicable diseases and other health conditions– complicating their prevention and control and negate current achievements. WHAT IS CAUSING CLIMATE CHANGE? • Greenhouse gases such as CO2, CH4, N2O and CFCs help the atmosphere to act as a blanket by trapping heat energy and maintaining its temperature close to the earth’s surface. • Global warming has been caused by excessive emission of these greenhouse gases (GHGs) into the environment through many anthropogenic activities. • It is this warming that is altering the world’s climate! 6 May 2017 Projections of Future Changes in Climate • For the next two decades, a warming of about 0.2°C per decade is projected for a range of possible emission scenarios. • Even if the concentrations of all greenhouse gases and aerosols had been kept constant at year 2000 levels, a further warming of about 0.1°C per decade would be expected. • Temperature and precipitation extremes will be more frequent; • Precipitation decreases likely in most marginal areas of the sub-tropical land regions, including Kenya.
