Updating of the feasibility study of the N’Débougou IV Project

Detailed description of project:

The N’Débougou IV project is part of a rehabilitation programme addressing irrigation infrastructure in the area of the Office du Niger (ON). The updated Feasibility Study focuses on the hydro-agricultural redevelopment of a network that will allow for the irrigation of approximately 4,200 ha via the following hydraulic infrastructure:

  • the irrigation network composed of the distributor of N'Débougou (22,945 m), 21 diverters and subdiverters (total length of 26,351 m) as well as sprinklers;
  • the drainage system consisting of the main drain of Siengo (26,565 m), the main drain of N'Débougou (12,617 m), 21 diverter drains and subdiverter drains (32,632 m) as well as sprinkler drains;
  • the plot comprising the irrigation and drainage ditches and the subdivision of the parcels by bunds.

In addition to the 4,200 ha of the N'Débougou scheme, the study will also cover the following four subprojects:

  • 345 ha coming from the diverter S12 of Siengo;
  • 548 ha of  N’Dilla;
  • the Grüber Nord Canal;
  • the improved irrigation of several village market gardens in the project area.

The surface area covered by the study totals 5,093 ha.

The study will also propose accompanying measures, identifying future project activities necessary for enhancing the agricultural exploitation of the rehabilitated irrigation schemes. In addition, the capacities of the various services of the ON will be assessed and their needs identified in terms of technical support in areas such as i) developing detailed design and tender documents, ii) assistance to the works contract, iii) control and supervision of the works undertaken, iv) guidance for the assignment and operation of works by farmers, v) providing advice for agricultural development.

Furthermore, an Environmental and Social Impact Assessment (ESIA) will be carried out according to the relevant national legislation and KfW standards. The purpose of the ESIA is to identify and assess the potential positive and negative environmental and social impacts of all phases of the proposed project. The ESIA process aims to provide information to develop an Environmental and Social Management Plan (ESMP), with a view to mitigating potential negative impacts, improving benefits and establishing continuous monitoring activities. This includes the presentation of proposed environmental and social mitigation measures (e.g., biodiversity protection, reforestation to meet firewood needs, observation of the water body and water quality, minimization of pollution in agro-chemicals, etc.).

Type of services provided:

  • Field investigations (topography by drone, soil analyses, geotechnics);
  • Elaboration of an inventory of infrastructure and assets to be rehabilitated (hydro-agricultural and socio-community infrastructures, civil engineering, tracks, plots, etc.) and evaluation of the current yield of plots per hectare;
  • Analysis of the availability of surface and underground water for off-season irrigation;
  • Analysis of technical options (wells, boreholes, motor pumps, solar, wind, Californian irrigation systems, drip irrigation, etc.) for the organisation of farmers and the profitability of small market gardening perimeters near the villages;
  • Diagnosis of drainage problems on the Dina backwater;
  • Comparative assessment of irrigation network design (manual regulation / automatic regulation);
  • Identification of needs for additional works (e.g., water points, laundries, schools, sanitary stations, water troughs, access tracks and bridges, storage warehouses, processing structures, fish ponds, small market gardening perimeters, etc.) and gathering information on potential donors;
  • Description of the works to be carried out (by contractors / beneficiary farmers);
  • Evaluation of necessary accompanying measures and related costs;
  • Cost estimation (works, consulting services, supervision of works, technical assistance for accompanying measures);
  • Proposal of a schedule for the execution of works;
  • Economic and financial cost-benefit analysis covering various options to diversify production systems;
  • Analysis of the availability and feasibility of agricultural equipment and campaign credits;
  • Development of the logical framework of the project;
  • Suggestions on the organisation, capacities and necessary support to farmers to assure financing of the infrastructure;
  • For ESIA: scoping study; stakeholder engagement; preparation of the project description; taking into account alternatives; description of the legal framework; preparation of the description of the initial state; identification and assessment of socio-economic and environmental impacts; development of the Environmental and Social Management and Monitoring Plan (ESMP); development of the framework for land acquisition, compensation, land relocation and redistribution (CATR); formulation of ESIA.
