Request for Expression of Interest (REOI) for the Selection of a Firm for GIS-Based Mapping of Erosion & Flood Sites in Imo State

Reference No.: IMS/NEWMAP/LCS/01/16


The Federal Government of Nigeria has received financing from the World Bank, Global Environment Facility (GEF), Special Climate Change Fund in addition to its own Fund towards the cost of the Nigeria Erosion and Watershed Management Project (NEWMAP) and intends to apply part of the proceeds for consulting services. The NEWMAP is an eight (8) year multi-sector and multi-scale programme with the objective to rehabilitate degraded lands and reduce longer-term erosion vulnerability in targeted States with acute gully erosion. Currently these states include: Anambra, Abia, Cross River, Edo, Enugu, Ebonyi, and Imo. However, seven additional States have recently joined the Project and these include: Kano, Kogi, Plateau, Sokoto, Delta, Gombe and Oyo.

The Imo State – Nigeria Erosion and Watershed Management Project (IMS-NEWMAP) being one of the States participating in the implementation of the Project intends to use part of the proceeds of this credit for GIS- based Mapping of Erosion and Flood Sites in Imo State and now invites eligible consulting firms (“Consultants”) to indicate their interest in providing the Services.


The Objective of the Consulting Services is to provide a Geographic Information System (GIS) – based map of gully erosion, flood sites and land use/land cover classification within Imo State. This will among others provide information on the status of gully erosion sites and land resources for effective management and monitoring of all erosion sites in Imo State. The duration of the assignment is Six (6) weeks


The Consultancy Firm for the GIS- based Mapping of Erosion and Flood Sites in Imo State will perform the following task:

(1)     Identification of the sites affected by flood and erosion in the state through proper ground ‘trothing’ and field completion.

(2)     Acquisition of spatially referenced data of both primary sources (such as attributes of selected sites, comprising of soil types, vegetation types, land cover types and geo-ecological characteristics of the area.

(3)     Acquisition of spatial data of secondary origin, such as topographic sheets and satellite images and other records.

(4)     Development of spatial database that can be updated from time to time and subsequently, build a GIS for erosion and flood (Erosion and Flood Information systems – (EROFLIS) from the acquired primary and secondary data arising in (1) to (3) above.

(5)     Conduct series of spatial analyses and modelling to produce map documents that can guide key policy and management decision making.

(6)     Derivation of geo-database on the priority erosion and flood sites in the state

(7)     Identification and delineation of major and minor watersheds in the state

(8)     Identification of other potential areas prone to gully erosion and flooding in the state and the classification of the degree of vulnerability/risk potentials.

(9)     Identification of the mechanisms and processes driving erosion and flood development in the state.

(10)   Produce maps that are easy to read.

(11)   Proffer best management practices that could mitigate the current problems and prevent future erosion and flood hazards in the state.


To be eligible, interested firms must provide information demonstrating that they have the required qualifications and relevant experience to perform the Services. The short listing criteria are:
