Gulu-Atiak-Nimule road project summary

The Uganda National Roads Authority (UNRA) recently commissioned a study to assess, cost and propose mitigation measures for the potential environmental impacts of the proposed construction and upgrade of the Gulu-Atiak-Nimule road (from Class B gravel to Class 2 bitumen standard).The proposed road measuring 104 kms will traverse the two districts of Gulu and Amuru in Northern Uganda.

The proposed construction and upgrade of the road will involve widening of the carriage way and road reserve, construction of bridges and laying of culverts and other auxiliary activities.

1.1.1  Objectives of the Study

The main objective of this study was to determine the likely positive and negative environmental impacts of the proposed upgrade of the Gulu-Atiak-Nimule road to bitumen standard. The study also aimed at estimating the magnitude and value of some of the key environmental costs and benefits. The study also proposed appropriate mitigation measures and an Environmental and Social Management Plan (ESMP) for the proposed road project.

1.1.2 Description of the Project Area

The proposed road traverses the two districts of Gulu and Amuru and covers a total distance of 104 km. The project area is located between latitudes 20o 15’ N and 30o 35’N and longitudes 31o 20’ and 32o 20’ E. The longer part of the road spanning nearly 100 km passes through Amuru District.

The road corridor traverses dominantly gentle sloping terrain particularly between Gulu and the Awer wetland System. Between Awer and Bibia, the terrain is mostly flat and gently slopes northwards towards Unyama Valley and wetland system and Nimule at the border with Sudan.

The area has very little surface water except for Layibi wetland and a small stream flowing through it, two small streams called Ladul and Oyitino near Lacor Hospital, Awer stream and wetland, Elego seasonal wetland and Unyama wetland and its drainage system.

The project impact area consists mostly of gently sloping terrain between Gulu and Awer wetland area in Lamogi Sub-county. From Awer and beyond Atiak Township, the proposed project area may be described as a flat plain, which gently tilts to Bibia Border post, and then slopes a little more steeply towards Unyama valley and wetland system towards Nimule.

The geology of the area is dominated by Pre-Cambrian rock formations comprising of quartzites, phyllites and undifferentiated acidic gneiss with some intermediate gneiss. The main soil types within the project area are vertisols, lothosols, alluvials, ferruginous and ferralitic soils. There is no evidence of soil erosion because the area is mostly flat.
