This paper explores the investments needed to achieve universal access to electricity in Sub-Saharan Africa by 2030, and the additional operation and maintenance costs these investments entail. It also explores the drivers of these costs, by exploring hundreds of scenarios that combine alternative assumptions on the level of service targeted, population growth, urbanization, industrial demand, and technology cost. The main driver of electrification costs is found to be the tier of service offered to newly connected households. The annual investment required to reach universal access varies between USD 14.5 billion per year on average for the basic access scenarios (0.7 percent of the region's gross domestic product per year over the period) and USD 22.7 billion on average for the high-quality scenarios (1 percent of gross domestic product). In the basic access scenario, costs depend mostly on industrial demand, which takes a large share of total demand. In the high-quality scenarios, costs depend on urbanization rates, as it is cheaper to connect urban households to the grid. Investment costs are not sufficient to provide reliable service, and when operations and maintenance are accounted for, total costs increase to USD 39.7 billion on average for the basic scenarios and USD 61.5 billion on average for the high-quality scenarios.

This paper presents a methodology to identify key priority areas for transport investments. The methodology uses a geospatial data-driven approach and then proposes an innovative economic analysis for project appraisal. The two main steps involve (i) prioritization of road interventions based on a set of economic, social, and risk reduction criteria; and (ii) assessment of monetized and nonmonetized costs and benefits of road interventions under many scenarios covering the uncertainty on future risks and other factors. This methodology is used at different stages of project preparation for a rural roads lending operation to the Government of Mozambique. In the two regions of Mozambique considered, the analysis prioritizes regions along the coast when combining agriculture, fisheries, poverty, network criticality, and hazard risk criteria. With a limited budget of USD 15 million per district, the results show that investing in repairing and rehabilitating culverts and bridges is the intervention that performs better under most of the scenarios.

The increasing cyber connectivity of vehicles and between vehicles and infrastructure will drastically reshape mobility in the coming decades. Although the advent of connected mobility is expected to benefit travelers and society by smoothing traffic, improving rider convenience, and reducing accidents, the augmented cyber components in connected and autonomous vehicles and related infrastructure also give rise to cyber attacks on the transportation system. Yet, little attention has been paid to transportation cyber resilience. This paper thus proposes an investigation on this topic with a comprehensive literature review. Cyber components and plausible autonomous mobility systems operation scenarios are discussed, before identifying possible cyber attacks to autonomous mobility systems at the vehicle and system levels. The discussion then moves to existing practices to enhance cybersecurity, and several strategies are investigated toward enhancing autonomous mobility system cyber resilience. At the vehicle level, creating layers and separation to reduce cyber component connectivity and deploying an independent procedure for data collection and processing are important in vehicle design and manufacturing. At the system level, recommended strategies include keeping redundancy in transportation capacity, maintaining a separate road network, and deploying different sub-autonomous mobility systems.

Climate change and climate policies will affect poverty reduction efforts through direct and immediate impacts on the poor and by affecting factors that condition poverty reduction, such as economic growth. This paper explores this relation between climate change and policies and poverty outcomes by examining three questions: the (static) impact on poor people's livelihood and well-being; the impact on the risk for non-poor individuals to fall into poverty; and the impact on the ability of poor people to escape poverty. The paper proposes four channels that determine household consumption and through which households may escape or fall into poverty (prices, assets, productivity, and opportunities). It then discusses whether and how these channels are affected by climate change and climate policies, focusing on the exposure, vulnerability, and ability to adapt of the poor (and those vulnerable to poverty). It reviews the existing literature and offers three major conclusions. First, climate change is likely to represent a major obstacle to a sustained eradication of poverty. Second, climate policies are compatible with poverty reduction provided that (i) poverty concerns are carefully taken into account in their design and (ii) they are accompanied by the appropriate set of social policies. Third, climate change does not modify how poverty policies should be designed, but it creates greater needs and more urgency. The scale issue is explained by the fact that climate will cause more frequent and more severe shocks; the urgency, by the need to exploit the window of opportunity given to us before climate impacts are likely to substantially increase.

Caribbean countries, a set of mostly Small Island Developing States (SIDS), have a history of dealing with large shocks. The region is threatened by both economic and natural hazards. Nations have specialized in tourism and commodity exports, disproportionately exposing them to global economic cycles through changes in tourism demand and commodity prices. They are also located in a region that is highly exposed to a range of natural hazards, from volcanic eruptions to earthquakes and hurricanes, which damage their infrastructure stock, reduce tourism demand, and destroy agricultural production. Hazards have often caused severe damage to economies and livelihoods in the region. This report reviews existing assessments of past losses from natural and economic shocks in the Caribbean, looking at impacts on physical capital, private sector activity (especially tourism and agriculture), economic growth, poverty, and well-being. It concludes that, despite the damage to physical capital experienced by countries due to natural hazards (especially in housing and transport infrastructure), the impacts on growth are short-lived, possibly because many mechanisms are in place to help economies bounce back rapidly. However, natural hazards have a high impact on poverty and human capital and threaten the sustainability of economic growth.
