TERMS OF REFERENCE FORFEASIBILITY AND DETAIL DESIGN STUDY FOR GATUNA IRRIGATION AND DRAINAGE PROJECT (167Ha) LOCATED IN GICUMBI DISTRICT

  1.  PROJECT BACKGROUND

The World Bank approved $300 million in financing under the International Development Association’s (IDA’s) grant, credit, and Scale Up Window to help the Government of Rwanda increase the use of irrigation and commercialization among producers and agribusiness firms in supported value chains, and to increase access to agricultural finance. 

The Commercialization and De-Risking for Agricultural Transformation Project (CDAT) will support the Government to provide services and create an enabling environment for the private actors throughout the agricultural value chain. It will finance public investments in the seeds sector, develop and rehabilitate irrigation systems on over 17,600 ha, provide accompanying land husbandry development on about 11,000 ha in surrounding water catchment areas to increase productivity and promote climate smart agriculture.

The project will also support commercialization by helping farmers’ access markets and availing matching grants for investments in mechanization, post-harvest infrastructure and processing equipment.  A CDAT challenge fund will invest in particularly innovative solutions for the sector that can be brought to scale. The project is nationwide and is foreseen to directly benefit at least 235,000 households, including women and youth. In partnership with financial institutions, the Commercialization and De-Risking for Agricultural Transformation Project will seek to enhance access to affordable financial services and products in the agricultural sector by providing short and long-term financing and reducing risks and challenges faced by agricultural value chains through strengthening market linkages and scaling up agriculture insurance.

One of the projects being considered for implementation by CDAT is the development of the lower part of Mulindi marshland located near Gatuna in Gicumbi District.  A Feasibility Study is required to consider alternatives for developing this marshland, and if reasonable alternatives are found a Detail Design study is then needed to support implementation of the project.   

  1. OBJECTIVE OF THE ASSIGNMENT

Rwanda’s economy relies heavily on agriculture as a sector contributing around 30% to the GDP. Nearly 70% of the rural population is employed in agriculture. The Government of Rwanda in its national policies clearly indicates agriculture as a vehicle for economic growth. The National Strategy of Transformation and PSTA IV emphasize agriculture development as a means to achieve the goal of poverty reduction and ensuring food security.

The goal of the project is to develop financially sustainable irrigation and drainage services, and increase farmers’ agricultural revenue in the project area.

The overall objective of the study is to undertake Feasibility and Detail Design studies to develop flood control, drainage, and irrigation for about 167 ha of the Mulindi marshland near Gatuna.  The study must meet the World Bank project appraisal requirements and should consider multipurpose development opportunities and ensure they are technically feasible, economically and financially viable, socially acceptable and environmentally sustainable.

The specific objectives of the assignment are to carry out relevant technical investigations and studies comprising of water resources (hydrologic and hydro-geologic) assessment, socio-economic assessment, agricultural soils and agronomic studies, topographical surveys, geotechnical investigations, hydraulic studies and design, and undertake feasibility and detail design studies for developing flood control and drainage of the Gatuna marshland. Similarly, the studies will determine the needs/demands and the potential for multipurpose infrastructure development. 

The study will be carried out in two phases; feasibility and detail design.  The feasibility study will select, examine, and rank various alternatives for flood control, irrigation and drainage.  If the feasibility study results in alternatives that seem reasonable to the Client, then the Consultant will proceed with the detail design study.  The feasibility study will examine three or four alternatives and provide design drawings, cost estimates, and economic analyses sufficiently accurate to enable decisions to be made on project viability.  In addition, the definition of the project components, organizational arrangements and procedures will be detailed enough to permit the executing agencies to use the study as guidance on project implementation.

  1. SCOPE OF THE STUDY
  1. General

The study will entail feasibility and detail design studies that include preparation of designs, cost estimates, and implementation arrangements for the finally agreed development alternative for irrigation, flood control, drainage, and watershed management associated with the project. The feasibility and detail studies will comprise analyses related to: (a) basin-wide water resources (qualitative and quantitative), (b) drainage and flood management, (c) watershed management plan, (d) topographic survey, (e) geologic and geotechnical investigations, (f) soils and agronomy, (g) cropping patterns, (h) overall agricultural potential and support services including market and value chain development for maximum land resource use (i) land tenure, (j) environmental and social analyses, (k) institutional analysis, (l) water management and operation and maintenance, and (m) economic and financial analysis in close consultation with farmer communities and other stakeholders. This project must adhere with international best practice, policies/guidelines and safeguards.

The Consultant shall define the benefits (direct and indirect) and costs, and determine financial feasibility, economic justification and cost recovery. The Consultant will adopt participatory approaches to ensure the optimal involvement of stakeholders from national to community levels, during the study. In planning and scheduling of the tasks, the Consultant should note that not all tasks will be conducted in linear fashion and the Consultant should propose a schedule on how the tasks can be scheduled to meet the objectives of the assignment and for optimal linkage/sequencing.

Gatuna – General Location

  1. Project Description

The Gatuna flooded area is located adjacent to the Uganda border in the downstream part of the Mulindi marshland in the valley between Cyumba and Kaniga Sectors of Gicumbi District in the Northern Province.  Approximately 167 ha or marshland that stretches about 2.7 km is frequently flooded, severely impacting the production of this fertile area.

Considering the rainfall pattern of the area and the current main crop which is tea in the valley, irrigation is not needed as much as drainage, but once it is realized that irrigation is needed during the dry season, the existing streams have high base flows which may be enough to fulfill irrigation requirements without the need for a storage dam. 

     Interceptor drain and main drain for Existing Scheme

Farmers in the most downstream 167 ha flooded area have shifted from tea to growing other crops on raised beds or have left plots in fallow.

The Consultant shall examine the reliability of water supply, considering the various existing and future water uses and identify appropriate water conveyance systems for different sections of the irrigation system to supply water to all parts of the land to be developed and recommend appropriate irrigation methods best suited for the command area. To adapt against potential adverse impacts of climate change and improve water management and use efficiency, the Consultant is expected to introduce such recent innovative water distribution options as using pipes for secondary and tertiary canals which allow for flow measurement, and regulating reservoirs which provide improved control of the main canal and reduce end spillage.

Moreover, the Consultant shall locate suitable irrigation water diversion structures in the command area and investigate pumping, storage or diversion requirements and reservoir operations required for irrigation with due consideration of floods and siltation in the command area.

    1. Drainage System Engineering Design

The Consultant will prepare preliminary designs for major structural and hydraulic elements of the proposed drainage system, including, the main conveyance system, on-farm surface and subsurface drainage system, open and or closed drainage canals system, flood protection and control considering both structural and hydraulic safety.

The Consultant shall take into consideration intensive labor engagement and use of local construction capability in case labor is available and local materials during the design as necessary. The Consultant shall prepare the layouts and drawings of the different project components using AutoCAD software. The Consultant shall also prepare a schedule of quantities in line with the latest Civil Engineering Standard Methods of Measurement (CESMM), for use in preliminary cost estimates and the economic and financial analysis.

    1. Formulation of Upstream Sustainable Land Management Actions

The task objective is to take stock of the baseline condition of the watersheds in the project areas and identify major erosion hotspots areas and interventions required to improve, protect and maintain the watershed in a healthy and sustainable manner.  This will in turn address sedimentation risks of drainage canals, irrigation systems and mechanical equipment in order to sustain the proposed infrastructure.

The Consultant should:

  1. identify/review watershed degradation hotspots in the catchments upstream; 
  2. identify current interventions being applied to combat catchment degradation, funding sources and the organizations involved;
  3. using soils, climate and topographic characteristics delineate priority areas for rehabilitation and management using satellite imagery, GIS or other techniques in the watersheds;

  5. consult the people living in the sample sub-catchment to understand their level of dependence on the resources of the watersheds;
  6. propose suitable soil, water and sustainable land conservation measures required to enhance the integrity and productive capacity of the watersheds; and
  7. undertake preliminary designs of measures for proposed upstream watershed improvement works to reduce erosion and sedimentation of drains and irrigation systems. This information will be used to estimate the associated impacts on the watershed and for financial and economic analyses.
    1. Environmental and Social Considerations – Strategic Environmental and Social Assessment

The Consultant will analyze the environmental and social aspects including land acquisition and resettlement sensitivities in each project area and, through the consideration of alternate project designs, develop project proposals that avoid or minimize potential adverse environmental impacts. Specifically, the Consultant should:

  1. assess environmental and social impacts that could make the project non-feasible or financeable, or result in costs likely to exceed the intended benefits when mitigation is taken into account;
  2. estimate the extent of resettlement and land and asset acquisition that would be associated with the project, and develop a preliminary concept of a development program for the area; and
  3. examine design alternatives such as lining main interceptor drain, flood attenuation reservoir, access road alignment, material sources (borrow areas), etc. and make comparison of such alternatives, in technical, economic, social and environmental terms, so that the best recommendations are passed on to the team members working on the engineering aspects for incorporation in the project designs.

The assessments will be guided by the national environmental including land acquisition and resettlement related legislation as well as World Bank safeguards.

The depth of the assessment will be sufficient to adequately inform the development of alternate project designs, the selection and justification of the preferred alternatives. Project alternatives that substantially convert or degrade important natural habitats should not be considered unless they include equivalent habitat restoration and maintenance within the project area or elsewhere.

A separate procurement for detailed Environmental and Social Assessment is being undertaken by the Client. The Consultant will coordinate his work with the Environmental and Social Assessment carried out under this separate consultancy and have feedback and incorporate the findings and recommendations of that study in this report.

Design features to avoid adverse impacts, minimize land acquisition and involuntary resettlement, or enhance environmental/natural resource services are to be clearly noted in the description of preferred project alternatives, with suitable maps. Acceptability of the final project design will depend not only on its technical and financial feasibility, but also on its environmental and social suitability, including transboundary considerations.

The Consultant shall establish construction schedules for the implementation of the irrigation and drainage system, outlet works as well as other irrigation and drainage infrastructures. Apart from the construction items of the earthworks and concrete works for the main structures these schedules shall include mobilization, construction of access roads as well as routes to borrow areas, mapping and information on quantity and quality of borrow areas, establishment of the construction camp, provision of housing and transport facilities for supervising staff, construction packaging, work methods and preliminary labor force requirements. In the schedules the Critical Path Method shall be applied. Based on this the disbursement schedule of the project main components will be estimated as an input for the financial and economic analysis.

    1. Preparation of Preliminary Cost Estimates and Benefits

The Consultant shall identify and value the costs and benefits that will arise with the proposed project for purposes of comparison with the situation as it would be without the project and determining the incremental net benefit arising from the project investment. This will involve preparation of financial cost estimates for the various project options and components with expenditure schedules for capital costs, replacement costs, O&M, management costs, etc. for all activities and services. A summary of the financial and economic cost estimates shall be provided in a tabular form and appropriately classified and discussed. All cost estimates must show the foreign and local currency requirements; taxes, subsidies shall be identified and their implications analyzed; physical and price contingency allowances should be quantified appropriately for each component/activity of the projects.

The Consultant should prepare estimates of project benefits, which should include: direct/indirect benefits, tangible benefits (arising either from an increased value of production or from reduced costs), intangible benefits (such as new job opportunities. The Consultant will also estimate secondary benefits created or costs incurred outside the project (using shadow pricing techniques/non-market valuation), so that they can be attributed to the project investment, in the economic analysis. Residual values must be calculated. Specifically, for the storage reservoir, the Consultant will identify multipurpose benefits deriving from upstream storage. They will propose a number of scenarios that differ in terms of the use of the stored water (irrigation, flood management, hydropower generation, municipal water supply, etc.) and that maximize the returns on investment in storage. Scenarios should include sensitivity tests involving climate change scenarios.

    1. Economic and Financial Analysis

The Consultant shall:

  1. compile and tabulate estimated incremental direct agro-economic financial benefit streams, prepared using constant prices (or suitably applied price projections if warranted) and appropriate assumptions; estimate likely build-up of agricultural production volumes and other benefits over the years following the initial investments and likely future production trends in a without-project situation
  2. undertake project economic and financial analysis using standard techniques for the irrigated agriculture as well as other identified uses. This should include determination of the financial and economic viability of the project, by carrying out analyses to determine the net present value (NPV), cost benefit analysis (CBA; B/C ratio), Net benefit – investment ratio (N/K) and financial and economic internal rates of return (FIRR, EIRR), including different discount rates.
  3. perform sensitivity analysis on important parameters (including calculation of switching values) to check their impact on the financial and economic viability. The Consultant should clearly list what assumptions are made and which key developments are needed to reach FIRR and EIRR.
  4. Carry out financial analysis of drainage and irrigation alternatives and compare the results to guide the client during selection of best alternative.
  5. Assess existing situation of current flood control and provide recommendations for action by CDAT as appropriate.
  6. Indicate specific areas that may have to be considered in more detail at the detail design stage and any major constraints and issues that will require resolution before the alternatives are taken to full design with, where possible, recommendations as to how and by whom action is required, specifying an appropriate timeframe.
  7. The Consultant will identify new better alternatives or make improvements to existing ones. 
  8. Based on the above steps, the Consultant will then recommend the most suitable alternatives and prepare a weighted alternatives selection criteria list to be used for ranking all identified alternatives including social, environmental, technical, and economic criteria.  This list should be included in the Inception Report. 

The key information for the project shall be presented in tabular format together with key environmental and social information. The Consultant should also provide documented analysis in Excel spreadsheets and based on this analysis make final recommendations on the way forward.

The Consultant will prepare the feasibility study and preliminary design reports for the scheme, which shall document the studies and investigations carried out, findings and information. The reports shall contain firm statements on the technical, economic/financial and environmental and social sustainability, and recommendations on project suitability and outlook, if necessary through a multi-criteria analysis. The reports shall include concise executive summaries to make the report more accessible to the public. The results of the investigations shall be compiled and appended either to the report or in a separate volume of the feasibility studies. This volume will aim at evidencing that the amount of investigation carried out brings a sufficient understanding of the site conditions to finalize the project layout and cost estimate with an acceptable level of contingencies at feasibility level. The reports will form a decision point on whether to advance the studies, in case viable options have been identified, or terminate the studies in case all options are non-feasible. In the former, the Consultant in consultation with the Client and stakeholders shall agree on the best design alternatives/layouts, for which detailed designs shall subsequently be prepared.

The client reserves the right to cancel the feasibility phase of the contract based on results of alternatives presented in the inception. If the option including the dam is chosen as best alternative, the consultant will elaborate the terms of reference for tendering the detailed design of selected alternative, but once the best alternative is only the drainage system the consultant will continue with detail design phase.
