Since the presentation of the World Bank’s first Africa Climate Business Plan
at the COP 21 in Paris in 2015 and the Transport Chapter in Marrakech in 2016, a lot of progress has been made on integrating climate adaptation and mitigation into our transport projects.
The World Bank initially committed about $3.2 billion toward mainstreaming climate action into transport programs in Sub-Saharan Africa in the form of infrastructure investments and technical assistance. Following the Paris Agreement, and building on African countries’ Nationally Determined Contributions (NDCs)
, the size of this portfolio grew to $5 billion for 2016 to 2020. In 2017, the institution added another $1.9 billion to that amount, bringing the total to $6.9 billion in projects with climate co-benefits— more than twice the size of the original portfolio. These investments will help improve the resilience of transport infrastructure to climate change and improve the carbon footprint of transport systems.
Climate change has already started to affect African countries’ efforts to provide better transport services to their citizens. African transport systems are vulnerable to multiple types of climate impact
: sea level rise and storm surge, higher frequency and intensity of extreme wind and storm events, increased precipitation intensity, extreme heat and fire hazard, overall warming, and change in average precipitation patterns. The increased frequency and intensity of extreme climate event challenges the year-round availability of critical transport services: roads are damaged more often or are more costly to maintain; expensive infrastructure assets such as ports, railways or airports can be damaged by storms and storm surges, resulting in a short life cycle and capacity than they were originally designed for. Critical infrastructure such as bridges continue to be built based on data and disaster risk patterns from decades ago, ignoring the current trend of increased climate risk. For Sub-Saharan Africa alone, it is estimated that climate change will threaten to increase road maintenance costs by 270% if no action is taken.
