Sécheresses, inondations, glissements de terrain, tempêtes : ces catastrophes naturelles liées aux conditions météorologiques se produisent régulièrement, mais leur fréquence et leur intensité sont vouées à augmenter sous l’effet du changement climatique. Depuis 1970, l’Afrique a connu plus de 2 000 catastrophes naturelles, dont près de la moitié au cours des dix dernières années seulement. Ces événements ont touché plus de 460 millions de personnes et causé le décès de 880 000 d’entre elles. Les estimations indiquent que 118 millions d’Africains vivant dans l’extrême pauvreté (avec moins de 1,25 dollar par jour) seront exposés d’ici 2030 à des sécheresses, des inondations et des vagues de chaleur extrême. Ces catastrophes à répétition entravent la croissance économique et privent encore davantage les populations démunies de la possibilité d’échapper à la pauvreté.

On the road to resilience: Reducing disaster and climate risk in Africa

Natural disasters—such as droughts, floods, landslides, and storms—are a regular occurrence, but climate change is increasing the frequency and intensity of such weather-related hazards. Since 1970, Africa has experienced more than 2,000 natural disasters, with just under half taking place in the last decade. During this time, natural disasters have affected over 460 million people and resulted in more than 880,000 casualties. In addition, it is estimated that by 2030, up to 118 million extremely poor people (living below $1.25/day) will be exposed to drought, floods, and extreme heat in Africa. In areas of recurrent disasters, this hampers growth and makes it harder for the poor to escape poverty.

Rising from the Ashes: How fires in Addis Ababa are shedding light on the need for resilience

On January 22, 2012 at 6:00 am in the morning, Ethiopians living in the Efoyta Market neighborhood in Addis Ababa woke up to a burning five-story building. More than 13 hours later, the fire had killed two people, destroyed 65,000 square miles including several homes and businesses, and produced damages amounting to ETB 20 million ($1 million), a huge amount in a country where nearly 30% of the population live on less than  $1.90 a day.   

Building African nations and communities’ financial resilience to climate and disaster risks

Sub-Saharan Africa is making significant economic and development strides. Yet, natural disasters, combined with the effects of climate change, rapid urbanization, and conflict situations are threatening these gains, keeping vulnerable and poor communities in a chronic cycle of poverty:
  • 425 million people who live in Africa’s drylands are highly exposed to climate shocks, and this number is set to grow by at least 50% by 2030. We cannot fully quantify the human cost, but Kenya alone suffered losses of $12 billion in the 2008 to 2011 drought. Official development assistance (ODA) in humanitarian aid to the Horn of Africa after the 2011 drought was $4 billion, 10% of all aid to Africa.
  • Africa’s coastal cities are engines of growth, but are highly vulnerable to flooding and sea-level rise. In the last three years, major floods have hit cities such as Maputo, Dakar, Lagos and Douala. Like droughts, floods won’t go away. Along with periods of extreme heat, strong winds and coastal storms, they are likely to become more frequent.
  • Ebola Virus Disease outbreak, from March 2014, was the most widespread, and reached epidemic proportions. The poor bore the brunt, lost their jobs and incomes, had difficulty accessing medical services and suffered psycho-social trauma. On a macro-level, Guinea, Liberia and Sierra Leone are estimated to lose over $1.6 billion in forgone economic growth in 2015.
  • Conflicts and disasters often reinforce each other to worsen negative development impacts and increase human suffering. From 2005 to2009, more than 50% of people affected by disasters lived in fragile and conflict-affected states (globally). Fourteen out of the 20 most conflict-affected states are in Africa.
