A dependable road network has the potential to move Africa’s economy forward, and to ensure everyone across the region can access opportunity and services.
... See More + However, road infrastructure is particularly vulnerable to climate change. In Africa, most projections are showing that higher temperatures, increased precipitation, and flooding will push an already stressed road system to the limit. As it prepares to invest heavily in infrastructure, the region has a unique opportunity to anticipate the consequences of a changing climate by retrofitting existing roads and adapting new ones. To support resilience in the road sector, a new World Bank study helps planners determine the most cost-effective and appropriate adaptation pathway under a variety of climate scenarios.

Africa has experienced economic growth of more than 5 percent per annum during the past decade, but to sustain this growth, investment in infrastructure is fundamental.
... See More + Much of these investments will support the construction of long-lived infrastructure (for example, dams, power stations, and irrigation canals), which will be vulnerable to the potentially harsher climate of the future. This book is the first to use a consistent approach across river basins and power systems in Africa, including a comprehensive, broad set of state-of-the-art climate projections to evaluate the risks posed by climate change to planned investments in Africa’s water, and power sectors. It further analyzes how investment plans can be modified to mitigate those risks, and it quantifies the corresponding benefits and costs, within the limits of a largely desk-based assessment. The scope of the study includes seven major river basins (Congo, Niger, Nile, Senegal, Upper Orange, Volta, and Zambezi) and four power pools (Central, Eastern, Southern, and West African). The study addresses the entire program for infrastructure development in Africa (PIDA) hydropower capacity enhancements in the subject basins, as part of the region’s overall power generation plans, as well as additional investments in irrigation that are included in regional and national master plans.

The World Bank has recently developed a method to evaluate the effects of climate change on six hydrological indicators across 8951 basins of the world.
... See More + The indicators are designed for decision-makers and stakeholders to consider climate risk when planning water resources and related infrastructure investments. Analysis of these hydrological indicators shows that, on average, mean annual runoff will decline in southern Europe; most of Africa; and in southern North America and most of Central and South America. Mean reference crop water deficit, on the other hand, combines temperature and precipitation and is anticipated to increase in nearly all locations globally due to rising global temperatures, with the most dramatic increases projected to occur in southern Europe, southeastern Asia, and parts of South America. These results suggest overall guidance on which regions to focus water infrastructure solutions that could address future runoff flow uncertainty. Most important, we find that uncertainty in projections of mean annual runoff and high runoff events is higher in poorer countries, and increases over time. Uncertaintyincreases over time for all income categories, but basins in the lower and lower-middle income categories are forecast to experience dramatically higher increases in uncertainty relative to those in the upper-middle and upper income categories. The enhanced understanding of the uncertainty of climate projections for the water sector that this work provides strongly support the adoption of rigorous approaches to infrastructure design under uncertainty, as well as design that incorporates a high degree of flexibility, in response to both risk of damage and opportunity to exploit water supply ‘windfalls’ that might result, but would require smart infrastructure investments to manage to the greatest benefit.
