Title: Environmental and Socio-economic Impact of Wadi Abu Soueid Water Harvesting and Spreading Project in Khartoum State, Sudan
Author: Mohamed, Awadalla; Ahmed, Somia
Abstract: This study was conducted to assess the ecological and socio-economic impacts of Wadi Abu Soueid rainwater harvesting and spreading dam - a project located in an agropastoral rural area on the eastern bank of the Blue Nile River in Khartoum State. Wadi Abu Soueid dam was established in 1997 by the State’s Ministry of Agriculture for improving rain-fed agriculture and rangeland in the area. A stratified random sample of five villages, located in the areas commanded by the water spreading dam, was chosen on the basis of distance from Khartoum. A proportional convenience sampling method was then used to select 50 respondents for interviewing. Primary data were collected through use of structured interview schedules, and secondary data were obtained from various relevant sources. The Statistical Package for the Social Sciences (SPSS) was used for data analysis. Comparative analysis for the periods prior to and after the establishment of Wadi Abu Soueid dam revealed significant differences in terms of sorghum productivity, size of livestock herds and production and marketing of milk and live animals. The analysis also revealed improvement in the density of natural grass and tree cover in the rangelands following the construction of the dam. However, some negative impacts of the water spreading dam were evident. These included a significant increase in the densities of the noxious Adar (Sorghum sp.) weed and semi-parasitic Buda (Striga hermonthica) plant, security problems (including trespassing on farmland and rangeland by nomadic groups from neighboring areas and animal thefts), and uncontrolled flooding of potentially productive farmland due to neglect of dam maintenance. Technical defects, relating to dam maintenance, and lack of follow-up activities resulted in loss of land due to uncontrolled flooding also became evident. Based on the findings of the study, a set of recommendations was put forward, including the scheduling of regular maintenance of the Wadi Abu Soueid and the other water harvesting dams, ensuring adequate follow up of pasture and crop land improvement programs, the introduction of improved crop varieties, and the intensification of technically coordinated extension programs for achieving sustainable use of the natural resources in the area.
