Request for Expression of Interest (EOI) for GIS-Based Mapping under the Nigeria Erosion and Watershed Management Project (NEWMAP) in Edo State, Nigeria 

This request for expression of interest follows the update of the general procurement notice for this project that appeared in UN Development Business issue of 27th April, 2012 and in Nigerian newspa­pers of 27th September, 2012.

As part of Governments commitment to transformation of the Nigerian socio-economy landscape, a multi-sector project is being executed in Nigeria to mitigate the vulnerability to erosion and support the people as they relate to their land. The Nigeria Erosion and Watershed Management Project (NEWMAP) is an 8-year multi-sectoral and multi-scale program that targets states with acute gully erosion. The proj­ect is involving many Federal and State Ministries, Departments and Agencies (MDAs), Local Govern­ments, communities and civil Societies who are responsible for planning, economy, finance, works, agriculture, water resources, forests, transport, power, emergency response as well as those focused on climate and hydrological information or watershed/basin regulation. In order to achieve this, the Fed­eral Government of Nigeria (FGN) has received a credit of US$500 million from the International De­velopment Association (IDA) for the implementation of the Nigeria Erosion and Watershed Management Project.

The EDO State Project Management Unit of the Nigeria Erosion and Watershed Management Project intends to use part of the proceeds of the credit for the recruitment of a competent consulting firm for the Mapping of Gully Erosion/flood Sites in the state and general landuse/landcover classification within the Geographic Information System (GIS) framework. The exercise is to help in knowing the status of gully erosion/flood sites and land resources in the state for effective management, monitoring and design of remediation works. The mapping will also underpin project presentation and reporting on key status of erosion sites especially the prioritized sites for the NEWMAP Gully Rapid Action and Slope Stabilization (GRASS) component.


The scope of the work includes the following:

(1)     Identification of the sites affected by flood and erosion in the state through proper ground ‘trothing’ and/or field visits which involve, appraisals, observations and measurements (sample/specimen col­lection).

(2)     Acquisition of necessary spatially referenced data of both primary source (such as attributes of se­lectee 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)   Assessment of the socio-economic impact of gully erosion and flood hazards on the people

(11)   Present in easy to read maps

(i)      Spatial extent of erosion in the selected area

(ii)     Spatial extent of Flood affected area

(iii)    Spatial analysis of socio-economic impacts of RAP action

(iv)    Selection of suitable site for resettlements

(v)     Predictive models of erosion and flood risk hazard based on anthropogenic, climatic and environ­mental factors

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

(B)       TIME FRAME

The assignment shall be completed within Twelve (12) weeks after signing of contract. (C)      EXPECTED OUTPUT/DELIVERABLES

The expected output includes:

(1)     Map of land use/ Land cover types

(2)     Maps of erosion and flood sites

(3)     Maps of predicted flood sites and likely affected areas

(4)     Map of erosion Risk hazard shown predicted annual soil loss

(5)       GIS of disaster risk that can be updated (specific to erosion and flooding)

(6)     Maps showing buildings that the RAP project will affect and the number of persons involved.

(7)     Maps showing the best location for rehabilitation for the affected persons

(8)     Catchment Area Delineation Maps.

The following deliverables will also be expected;

(i)      Six (6) hard copies and electronic version of Inception Report with detailed work plan and indicators of performance. To be delivered within one week of signing the contract;

(ii)     Eight hard copies and electronic version of Draft Report to be submitted to the client and circu­lated for comments and relevant issues raised incorporated into revised version. This will be delivered three (3) weeks after submission of inception report.

(iii)    Final Report to include a concise Executive Summary with all annexes and bibliography and the dissemination/disclosure plan, to be delivered 2 weeks after submission of draft report.
