Vol. 9, No. 4, 2020, pp. 71-76. doi: 10.11648/j.wros.20200904.11 Received : May 13, 2020; Accepted : June 12, 2020; Published : September 8, 2020 Abstract: The aim of this overview is extended to indicate the Potential Sources, Soil salinization and expansion level of lake Basaka. Lake Basaka is located in the middle Awash River Basin, Central Rift Valley of Ethiopia at about 200 km south East of the capital city, Addis Ababa. The lake is expanding as opposed to the other rift valley lakes in Ethiopia, which are shrinking, Lake Basaka is found to be expanding at an alarming rate. This overview indicates the expansion area/level/ of the lake is challenging the socio-economics and environment of the region significantly. With this point of view the lake’s expansion is due to the agricultural sugarcane farm land use type near Beseka Lake and mostly due to the increased ground water flux to the lake.

Th e data were primarily collected using qualitative research methods such as key informant interviews, group discussions, fi eld observa- tions, and records of community meetings and non-governmental organization (NGO) project reports. In the last decade and a half, several attempts were made by NGOs and local governments to encourage pastoralists to revive their traditional practices of setting aside grass reserves for seasonal grazing, but only a few such private enclosures were established.

  • Effect of Lake Basaka Expansion on the Sustainability of Matahara SE in the Awash River Basin, Ethiopia
    OLUMANA, LOISKANDL & FÜRST 34th WEDC International Conference, Addis Ababa, Ethiopia, 2009 WATER, SANITATION AND HYGIENE: SUSTAINABLE DEVELOPMENT AND MULTISECTORAL APPROACHES Effect of Lake Basaka expansion on the sustainability of Matahara SE in the Awash river basin, Ethiopia Megersa Olumana, Ethiopia, Willibald Loiskandl & Josef Fürst, Austria REFEREED PAPER 296 Matahara Sugar Estate (MSE) establishment nearly 40 years ago is experiencing effects of a rising GW table and salinity in some fields, and as the result the yield of certain fields is decreasing and a significant area of cultivated lands are abandoning The problem is believed to be the result of the expansion of saline Lake Basaka towards the plantation field. The objective of this study was to determine the extent of expansion of the Lake (area & shape) in the past 35 years period from Landsat images and assess its negative effects on the nearby sugarcane plantations’ GW dynamics & soil salinity. The result indicates that the lake expanded approximately 34 km 2 in the past 35 years. The GW table is very shallow in the Abadir­ extension areas and north section where the GW salinity is under severe condition. Introduction Lake Basaka is located in the middle Awash River Basin, Central Rift Valley of Ethiopia at about 200 km South­East of the capital city, Addis Ababa. The lake is expanding as opposed to the other rift valley lakes in Ethiopia, which are shrinking (Alemayehu et al., 2006). Currently the total surface area of the lake is estimated to be 42 km2 , which was about 3 km2 in the 1960’s (Gulilat, 2000; Alemayehu et al., 2006).

  • Karrayu Conflict in the Awash Valley
    Dynamics of Pastoralist Relations at Change: An Exploration into the Causes of Afar -Karrayu Conflict in the Awash Valley Asnake Menbere1 Abstract This study is an exploration of the underlying causes and the dynamics of the conflict between the Afar and Karrayu pastoralists in the Awash Valley of Ethiopia. Its prime objective was to uncover the interplay of causes and dynamics of the conflict between these two ethnic groups. It entirely relied on qualitative method; therefore, used both primary and secondary sources in the process. The primary data was generated through both in-depth interviews and Focus Group Discussions. The study indicated that the causes of the conflicts in the areas are multiple; relating to socially generated natural resources scarcity, inappropriate development interventions, cattle rustling and related revenge attacks, culture of violence emanating from cultural values and devaluing of traditional institutions and resemblance of pastoral lifestyle. Above all, the marginalization of pastoralists from major political, economic and other considerations, and prejudices attributed to the pastoralist way of life has led to persistent social conflicts. Besides, memories of historical animosities between the Afar and Karrayu ethnic groups served as adhesive glues for the pervasive conflict, mounting negative attitudes and perceptions to each others’ group. The dynamics of these causes across time can be associated with the involvement of various actors with incompatible personal/group interest and needs. In an attempt to address the causes of conflict, efforts have been made so far through formal and informal institutions but in vain. Therefore, peace building endeavors should consider the burning and at times diametrically opposed interests of the parties, and have to address the major cause/s of the conflicts through both changes in attitude and in the application of policies designed within the context of the region that is first consulted and largely approved by the local people.

Receiced 26 July, 2019; Accepted 10 September, 2019 Soil salinity is a threat for agriculture under irrigation as it affects the growth and development of plants and the problem is widespread in middle Awash where Amibara irrigated farms are present. Therefore, Measurements of groundwater depth were taken from thirty piezometers in the months of August, September, October, November and December to investigate spatial variability and temporal fluctuation of groundwater depth in Amibara irrigation scheme. Based on the field measurement, relatively shallow water levels were recorded in Vertisols area as compared to that in Fluvisols area with a mean values of 1.47 m and 3.01 m, respectively. On the other hand groundwater depth was influenced by the type of field cover and irrigation practices taken place during the sampling periods. Relatively deep water table was recorded in fields covered by shrubs and tree plants as compared to cotton and sugarcane fields with mean groundwater depth values of 4.87, 2.48 and 1.78 m, respectively. Seasonal fluctuation of groundwater depth was influenced with the climatic condition and irrigation practices occurred at the study area.

One of the primary concerns is the elevated salinity and the degradation of water Lake Beseka quality in the Awash River. Located in the Great Rift Valley in Ethiopia, the Awash River has Climate change unique hydrochemistry due to water-rock interactions. However, in recent years, increasing anthropogenic activities including the discharge from saline Lake Beseka into the Awash River has caused some concern. This study used an Integrated Catchment Model to simulate chloride concentration in the Awash River Basin by taking both natural and anthropogenic sources of salinity into consideration. Future scenarios of climate change and Lake Beseka discharge were examined to assess the impact to the river water quality.
