THE WORLD BANK TERMS OF REFERENCE VULNERABILITY OF THE BANGLADESHI TRANSPORT NETWORK TO NATURAL DISASTERS AND CLIMATE CHANGE, AND POTENTIAL ADAPTATION OPTIONS A. PROJECT BACKGROUND AND OBJECTIVES The Sustainable Development Chief Economist’s office oversees technical work and analysis from the World Bank Group’s Global Practices that draws together the best expertise from across the institution and its partners to help countries tackle their most complex challenges in the area of sustainable development and embark upon greener growth pathways to attain this level of sustainability. The cluster of global practices includes the following practices: agriculture, energy and extractives; environment and natural resources; social, urban, rural and resilience; transport and ICT; and water. This project will focus on assessing the vulnerability of the Bangladeshi transport network to natural disasters and future climate change impacts, and on looking for cost-efficient adaptation options. In Bangladesh, transport connectivity is challenged by its geography (in particular by the presence of four major rivers: Ganges, Meghna, Jamuna, and Padma) and by a predominantly rural population distribution. In addition, the country is exposed to recurrent floods that can create severe disruptions in some segments of the transport network, with potentially high economic and social consequences. The country also has to face, among other challenges, changes in river morphology, sedimentation issues, and storm surges. Yet, providing reliable connectivity is key for reducing poverty, increasing access to markets, improving trade competitiveness and achieving inclusive green growth. Despite the natural disasters that challenge the Bangladeshi complex transport network, and despite the fact that disruptions may increase in the near to long-term because of climate change, exponential demand for mobility in Bangladesh requires rapid build-up of new infrastructure and upgrade of existing infrastructure. Decision-makers have to develop the transport network, ensure that it keeps performing well under any circumstance and that the costs associated with potential disruptions remain minimal. It is important to guide this transition to make sure the infrastructure that is being built now will keep supporting economic growth and poverty alleviation for the next decades. Objectives This analytical study intents to help Bangladeshi decision makers prioritize and compare alternative interventions in the transport network taking into account the network’s adaption to climate events. This approach implicitly implies that interventions –investment, maintenance and other adaption options— will be assessed through an economic lens as much as their impact on increasing resilience of the road network uncertain natural hazards. It is expected that this study will analyze the criticality and vulnerability of the transport network in Bangladesh. It will build on a small but growing body of work on how to deal with the deep uncertainties pertaining to future road disruptions (e.g. because of climate change), future traffic demand or other socio-economic variables, when making investment decisions (Halim, Kwakkel, and Tavasszy 2016; Espinet, Schweikert, and Chinowsky 2015). In addition, it will address 3 important methodological concerns in terms of how to (i) measure economic costs of disruption, (ii) model traffic reallocation in TOR April 2016 road networks once a link or a road is partially or totally disrupted, (iii) make the method replicable and introducing explicit linkages to current World Bank operations/interventions selection and design. B. SCOPE OF WORK In order to guide decision makers in Bangladesh, the consultants will combine spatial and economic analyses to identify the most critical assets in the transport network and the best investment options to increase the performance and resilience of the network. To deal with the uncertainty on the future natural hazards, but also traffic and local economic activities, the consultant is expected to apply approaches and tools labeled Decision Making under Uncertainty (DMU) (Kalra et al. 2014; Haasnoot et al. 2013; Lempert and Kalra 2011). These approaches will properly deal with the uncertainty on impacts of future natural hazards, as well as the uncertainty on future traffic demand. These approaches are currently being developed to manage deep uncertainty and disagreement in World Bank projects. DMU approaches do not intent to predict the future but they rather assess the performance of alternative network configurations under many possible futures. DMU tools identify the vulnerabilities of different interventions and allow decision-makers to choose the most robust options. Key questions include: (1) What are the potential economic and social costs associated with disruptions of the current transport network? (2) Where are the critical segments of the network that deem built-in resilience and/or redundancy? (3) What are the most robust alternatives (maintenance, redundancy, traffic management, alternative construction standards, temporary bridges, sediment management etc) to reduce the vulnerability of critical segments to future climate events? C. ACTIVITIES Through this TOR, the consultant will help the World Bank answer the questions presented above. In particular, the consultants will: (1) Build a model of the transport network in Bangladesh; the complexity of the model will depend on data availability, but it is expected to include at least primary and secondary roads, bridges and waterways. Calculate several relevant performance metrics for the road network comparing infrastructure-based metrics with economic- and social- based metrics (e.g. cumulated road user cost on least cost routes, average number of kilometres for the least-cost routes, measures of redundancy, total network cost combining road user cost with traffic flows) (2) quantify the relative criticality of different assets (e.g. road links and bridges), based on the effect of a link disruption on the performance indicators calculated previously; here assumptions will have to be made on re-routing and on the proportion of vehicles who may abandon their journey; (3) Assess the expected economic losses associated with natural disasters disruptions, in many different scenarios, for the most critical assets in the network; identify the uncertainties that matter the most for these expected losses. Here several uncertainties may have to be taken into account, including climate change, duration of disruptions and future traffic demand. (4) Assess the robustness of different intervention options for the critical assets, in order to increase the resilience of the network; assess the trade-offs between multiple criteria. (5) Help the World Bank team provide recommendations to the Government of Bangladesh on investment priorities in the transport network. TOR April 2016 Through this TOR, the consultants will also participate in one or two workshops in Bangladesh, first to better scope the analysis and then to discuss the results with the Government of Bangladesh. D. DELIVERABLES/SPECIFIC OUTPUTS EXPECTED FROM CONSULTANT This analysis will be mostly delivered in the form of data files and a memo outlining the data, methods used and results. The models built to carry the analysis will also be delivered to the World Bank team at the end of the project. The duration of this consultancy is 12 months. Any modifications to this timeframe must be agreed upon in writing with the relevant World Bank team. The firm will be paid upon presentation of invoices and contingent upon timely submission of agreed deliverables. Payment Deliverable Weeks after signing contract 1 Deliverable 1.
