The proposed activity aims to evaluate the reverse auction mechanism to attract private investments in resilient digital infrastructure in access networks (last mile) to broadband services in Chad; beyond the market frontier; that is; in areas that are economically unprofitable in the short term.The study will draw on lessons learned from ongoing experiments in Tanzania (Digital Tanzania Project); Niger (Smart Villages for Rural Growth and Digital Inclusion); Benin (Digital Rural Transformation Project) and Côte d 'Ivoire (E-Agriculture Project) to assess the relevance of such an approach in a fragile context like that of Chad; improve the design of the so-called approach to mobilizing private capital (MCP) and if necessary propose an alternative approach which was more appropriate for the Chadian context.The feasibility study will make it possible to measure the willingness and capacity (technical; financial and organizational) of private operators to deploy and operate broadband infrastructure in areas that are not economically viable in the short term; provided they benefit certain investment subsidies.The tasks associated with this activity are as follows:(i) Mapping of unserved areas in terms of broadband access and services;(ii) The inventory of energy (electricity network); social (health centers and schools) and economic (market and other) infrastructures available in these unserved areas as well as the estimate of the population of each locality;(iii) Identification of the reasons for market failure in these areas;(iv) Estimation of demand for digital services in unserved areas(v) Determining the investment in digital infrastructure necessary to cover unserved areas and;(vi) Estimating the amount of public funding needed to incentivize private operators to invest in broadband infrastructure in order to extend their networks beyond the market boundary.The duration of the mission is 4 months; from the date of signing the service order.
