It represents a potentially important intra-Regional link between Assosa in the south and Guba in the north (Annex A Map 2). The area of influence falls entirely within the Abay River (Blue Nile) basin and includes most part of its major tributary Dabus River Basin. The drainage flows predominantly in a northward direction, while the Abay itself turns westwards into Sudan near Bambudi in the north of the project area. The road project is approximately 219 km long of which some 80 km is presently impassable and the remainder gravel or cleared access. Further, there is an approximately 250 meter unbridged river crossing over the Blue Nile about 50 km south of Guba, as well as a number of other river crossings. Some 80 km of the proposed road alignment is new, or follows only old trading tracks and/or Old Italian military roads. This part of the road will pass through a rolling to hilly area, for which there are few secondary data resources. The current development objective of the road is to access agricultural potential in the Region and to provide intra Regional links in Benishangul-Gumuz. This is consistent with other development plans for the Region, notably the Abay River Basin Master Plan. Potential includes the development of large-scale irrigated agriculture in the Abay River Valley, and perhaps, the Dabus. In addition, the Region is believed to have mineral deposits, primarily gold, marble and base metals. The desire is to open the area to exploration and subsequent resource extraction. The EIA The EIA consisted of scoping according to Ethiopian EPA standards, a biological survey, a socio-economic baseline study, and five public consultations held with affected communities. In order to assess the potential impacts of the road works, propose possible mitigation measures and establish an environmental management plan, the Consultant assumed a work methodology based on the normal approach that most contractors would apply to execute the types of works anticipated for the project road.
