Six projects from six countries were selected as the cases for detailed analysis in this study. They are from Argentina, Botswana, India, Kenya, Lao PDR and Paraguay, representing a wide range of geographical distribution. Also, the extent of the effect of economic downturn which these countries experienced ranges a wide variety. In an economic downturn, uncertainties increase with many inputs of road projects Cost Benefit Analysis (CBA), including fuel prices, levels of demand, investment costs and maintenance availability. Also, important parameters of project evaluation such as discount rate and value of time need to be more carefully scrutinized. Therefore, it is very important for the developing countries to have good understanding about the effects of the variability of these inputs/parameters on project viability and the ranking of road investments. It is a role of the developing agencies to conduct a systematic analysis of these effects and disseminate the findings and knowledge obtained. The objective of the study is to obtain insights regarding the effects of varying inputs and parameters on the viability of road projects through case studies using Highway Development and Management Model (HDM-4), thereby to facilitate the formulation and implementation of road projects that increase the welfare of the society under the environment of increased uncertainty in an economic downturn. The results of the study will be summarized in a transport note as a discrete knowledge product and disseminated among various stakeholders including developing agencies staff, government officials and donor communities. To assess the effects of increased uncertainty with inputs of cost benefit analysis on the economic viability of road projects, this study first investigated the range of variability of the inputs for the six selected projects/countries. It was found that the variability ranges differ by country reflecting the degree of decrease in transport demand and relative change in factor prices due to economic downturn.

A high-speed rail service can deliver competitive advantage over airlines for journeys of up to about 3 hours or 750 km, particularly between city pairs where airports are located far from city centres. One suitable type of corridor is that which connects two large cities 250-500 km apart. But another promising situation is a longer corridor that has very large urban centres located, say, every 150-300 km apart. On these longer corridors, typical of some being built in China, high-speed rail has the ability to serve multiple city-pairs, both direct and overlapping. The overall financial performance of high-speed train services depends on enough people being able to pay a premium to use them. In Japan there is a surcharge for high-speed rail which doubles the fare on conventional services. China high-speed train fares are about three times conventional train fares. But in order to generate the required volume of passengers it will usually be necessary not only to target the most affluent travelers but also to adopt a fare structure that is affordable for the middle income population and, if any spare capacity still exists, to offer discount tickets with restrictions on use and availability that can fill otherwise unused seats. The combination of supportive features that exist on the eastern plains of China including very high population density, rapidly growing disposable incomes, and the prevalence of many large cities in reasonable proximity to one another (creating not just one city-pair but a string of such pairs) are not found in most developing countries. Nor could all countries assemble the focused collective capacity building effort and the economies of scale in construction costs that arise when a government can commit the country, politically and economically, to a decades-long program over a vast land area. Even in China, the sustainability of railway debt arising from the program as it proceeds will need to be closely monitored and payback periods will not be short, as they cannot be for such "lumpy" and long-lived assets. But a combination of those factors that create favorable conditions of both demand and supply comes together in China in a way that is distinctly favorable to delivering a successful high-speed rail system.

Despite the long relationship between the European Union and the African, Caribbean, and Pacific (ACP) countries aimed at encouraging their exports while stimulating growth and investment, the ACP states still face difficulties in integrating into the world economy. The author examines the non-least developed ACP countries ' preferential trade with the EU. Her objective is to explain the determinants of preferential exports of ACP countries toward the EU and to assess the impact of preferences on trade volumes. The author also investigates the existence of a threshold in the offered duty reduction under which traders have no incentives to ask for preferences.

Ports have always played an essential role in this highly trade-dependent region. While there are still wide disparities in terms of throughput volumes and capacity, traffic has been growing rapidly in most countries over the last decade. Overall, total throughput in West Africa grew from around 105 million tons in 2006 to 165 million tons in 2012. Likewise, containerized traffic remains limited in West Africa compared to other regions but has grown faster than in any other region in the world over the last five years. The combined throughput of container terminals in the region reached almost 5 million twenty-foot equivalent units (TEUs) in 2013, twice as much as a decade ago, and is expected to keep growing fast. The future throughput of West African ports comprises the demand for containerized trade generated by coastal and landlocked countries, and additional port movements generated by transshipment in regional hub(s). Given the regional dynamics of ports in West Africa, there is also a good case for more cooperation between West African countries on port reform, competition and regulation. Strengthening the capacity and mandate of regional institutions such as the ECOWAS Commission on these issues would complement regulatory efforts at the country level and provide a forum to analyze regional issues related to inter-port competition and private sector participation in port management.

This study is a product of the Africa Infrastructure Country Diagnostic (AICD), a project designed to expand the world's knowledge of physical infrastructure in Africa. Infrastructure contributed 1.8 percentage points to Cote d'Ivoire's annual per capita Gross Domestic Product (GDP) growth in the mid-2000. Raising the country's infrastructure endowment to that of the region's middle-income countries could boost annual growth by a further two percentage points per capita. Cote d'Ivoire made major strides with respect to infrastructure during the 1990s. As a result, the country has broad-reaching national backbones in the road, energy, and Information and Communication Technologies (ICT) sectors, and relatively high levels of household coverage for utility services. However, much ground was lost to conflict in the mid-2000s. Very little investment has taken place in the last fifteen years, leading to recent power shortages, the deterioration of the road network, and the deceleration of progress on safe water access. Cote d'Ivoire's most pressing challenge will be to regain the financial equilibrium needed to restore a reliable energy supply. Reestablishing the prominence of Abidjan's port will require investments in terminal capacity, as well as road and rail infrastructure upgrades on hinterland linkages. The underfunding of road maintenance must also be addressed. Another challenge lies in sanitation, as it is currently unlikely that the country will meet the associated millennium development goal. This report presents the key AICD findings for Cote d'Ivoire, allowing the country's infrastructure situation to be benchmarked against that of its African peers. A social and economic crisis in Cote d'Ivoire has crippled its growth trajectory, which had been that of a middle-income country. It will therefore be compared to low-income countries (fragile and non-fragile groups) and middle-income countries, as well as immediate regional neighbors in West Africa. The study presented several methodological issues.
