9. Why ClimAfrica? What ClimAfrica? Africa is probably the most vulnerable continents to climate change and climate variability, because of the combination of low adaptive capacity and particular eco-climatic and socio-economic conditions (i.e. sea level rise, flooding, drought, desertification, poverty, conflicts, urbanization, population growth, diseases, etc.). The majority of African population rely on rain fed agriculture. Hence, food production directly depends on climate, making economy and livelihood to be significantly at risk because of climate change. ClimAfrica is conceived to respond to the urgent need for the most appropriate and up-to-date tools to better understand and predict climate variability and change in Africa, assess their impact on ecosystems and population, and develop suited adaptation strategies.

10. How ClimAfrica? Who ClimAfrica? The ClimAfrica consortium is formed by 18 institutions, 9 from Europe, 8 from Africa, and the Food and Agriculture Organization of the United Nations (FAO). ClimAfrica Work Plan The work is organized in eight complementary work-packages: WP1: Past climate variability WP2: Modelling seasonal to decadal climate predictions WP3: Climate impacts WP4: Medium-term warning system, vulnerability, adaptation WP5: Socio-economic implications WP6: Case studies in Africa WP7: Project Management WP8: Dissemination ClimAfrica Objectives 1- Develop improved climate predictions on seasonal to decadal scales 2- Assess climate impacts in key sectors of Sub-Saharan Africa economy, such as water resources and agriculture 3- Evaluate vulnerability of ecosystems and population to inter-annual climate variations and longer trends (20 years) 4- Suggest and analyse new suited adaptation strategies 5- Develop a new concept of mid-term monitoring and forecasting warning system (for food security, risk management, civil protection).

WP1 - past climate variability Recent trends in the water cycle of Africa Recent trends in the water cycle of Africa WP1 – Past Climate Variability Collection and synthesis of various data streams that diagnose the variability of the climate, in particular the water cycle, and the productivity of ecosystems in the past decades. The data streams range from ground based observations and satellite remote sensing to model simulations. WP1 aims at providing consolidated data to other WPs in ClimAfrica, and at analyzing the interactions between climate variability, water availability, and ecosystem productivity of Sub-Saharan Africa.

23. Autumn 2012 predictions: Precipitation anomalies Precipitation anomalies for Oct-Nov-Dec 2012: This figure shows the precipitation anomalies: the difference between the predicted precipitations and the long term average. Brownish areas are expected to be drier than normal, while blue regions are expected to be wetter than normal. The figure below shows the probability that the anomalies predicted above will occur. Cold colours show areas with high probability of precipitations above average. Warm colours show areas with high probability of precipitations below average.
