Sub-Saharan Africa knows more than its fair share of disasters induced by natural hazards. The past few months alone have seen drought in the Horn of Africa, floods in Mali and Rwanda, and landslides in Ethiopia and Uganda. Between 2005 and 2015, the region experienced an average of 157 disasters per year, claiming the lives of roughly 10,000 people annually.
With all the other hazards facing Africa, it’s easy to forget that East Africa is home to the 6000-km long Rift Valley System—the largest continental seismic rift system on earth. The sub-region covers 5.5 million km2 and is inhabited by about 120 million people.
The Rift Valley is not subject to the high-magnitude earthquakes that we see along subduction zones, such as those in the Ring of Fire—the area in the basin of the Pacific Ocean known for its many earthquakes and volcanic eruptions—which can produce catastrophic consequences, as we’ve just seen in Indonesia. In the Rift Valley, residents have not experienced a high-magnitude earthquake in their lifetime, leading many people to deduce that the seismic risk is low or non-existent.
For thousands of years, the Niger River has been the lifeblood for not only Niger, but also its neighboring countries in the Niger River Basin. Yet, even as many Nigeriens depend on the mighty waterway for food, water, and livelihoods, the Niger River also poses a severe flood risk to the West African country during the rainy season. In the third quarter of 2017, widespread flooding due to heavy rains claimed the lives of over 50 people and displaced nearly 200,000.
To celebrate World Environment Day, hundreds of Freetonians came together to plant a tree in honor of the more than 1,000 people killed and missing after devastating landslides and floods tore through Freetown less than a year ago. The landslide and flood waters ripped through the capital city with tremendous energy, destroying everything in its path. It was reported that a huge wave of boulders, building debris and mud cascaded down the river channel immediately after the landslide. The disaster affected more than 6,000 people and caused significant destruction and damage to critical infrastructure.
As we reflect on 2017, the truly devastating impact of climate change is being felt across the globe. The evidence has never been clearer that the impact of climate change is happening now. The World Bank's “Shockwaves” report estimates that, without major investment, climate change will push as many as an additional 100 million people into poverty by 2030.
Over half of the 12 million people living in Somalia are acutely food insecure. This adds to the development challenge for Somalia after more than two decades of civil war and political instability. In particular, the urgent need for humanitarian assistance bears the risk of fostering aid dependency. To embark on a sustainable pathway toward development instead, intervention should rely on markets (whenever possible), and react dynamically to changes in market equilibria.
Therefore, we started to monitor 14 Somali markets and publish the data in near real-time using something similar to what we use for South Sudan, the innovative survey and analysis methodologies.
Rocky shores that hardly measure more than several meters at high tide are all that are left of some of Senegal’s most highly prized beaches at the seaside resort Saly. With every year that passes, the Atlantic ocean inches closer, much to the dismay of locals and tourists alike. 25% of the Senegalese coast is at high risk for coastal erosion, and it is estimated that this figure will increase to 75% by 2080 if sea levels continue to rise. A victim of climate change, Senegal tourism has taken a hit despite being one of the key focus areas of the Plan Sénégal Émergent, the country’s long-term growth and development strategy.
