Land and water digital media series # 2. Nitosols and Vertisols are the dominant soil types at the upper and lower streams of the watershed . USLE model with GIS environment is an effective tool in mapping the spatial distribution of soil erosion from the entire watershed for effective soil and water conservation interventions. 0000002547 00000 n The soil types in maybar watershed is mostly dominated by sandy clay loam covering 80% of the watershed, and the rest is clay loam. /BaseFont /ArialMT This study has been conducted at Dijo watersheds in the Rift valley Basins of Ethiopia to estimate soil erosion rate and identify erosion hotspot areas for proper planning using Geographic Information System and Universal Soil Loss Equation adapted to Ethiopian condition. The finding was also consistent with the finding of Belayneh et al. The clay loam, Similarly, Hurni et al. The required data collected for analysis are included in the manuscript. There are a number of dry habitat reptiles including the endemic geckos, Arnold's leaf-toed gecko (Hemidactylus arnoldi) and Parker's pigmy gecko (Tropiocolotes somalicus). /Subtype /TrueType The current finding on erosion was evaluated based on the past 10years land use land cover scenario; therefore, soil erosion might be reduced if the current land use land cover scenario considered. Soil erosion could accurately be estimated if and only if the extent and distribution of gullies should be measured. Hawassa, Ethiopia, Wischmeier W, Smith D (1965) Predictingrainfall erosionlossesfrom CroplandEastof theRockyMountains:guidefor selectionof practicesfor soiland waterconservation. The highest soil loss in vertisols could be due to their low infiltration rates when wet and relatively higherodibility. 0000017099 00000 n 2015 Springer Science+Business Media Dordrecht, Billi, P. (2015). Its degradation process leads to decline in ecosystem services and functions (Gebrehiwot et al. Composed of vertisols, they have medium to high potential for both food and agriculture but pose tillage problems because they harden when dry and become sticky when wet. Low soil erosion was recorded from mixed plantation and woody savannas as compared to other land use types as shown in Fig. The mountains consist of plateaus separated by valleys and rising to pinnacles. 7 Sedimentation must be slow.Otherwise, the time will be too short to form sufficient pyrite for 5 0 obj Finally, the integration of USLE and GIS is an effective tool in mapping the spatial distribution of soil erosion from the entire watershed. Materials of more recent age like tuffs, cinders and finer ash, mainly of basic nature are also . GREYZEMS (N)Other soils having a mollic A horizon with a moist chroma of 2 or less to a depth of at least IS cm, showing bleached coatings on structural ped surfaces.

Lithosols were defined as: "soils other than Histosols that were limited in depth by continuous coherent and hard rock within 10 cm of the soil surface." Podzols having a thin iron pan in or over the spodic B horizon, Other Podzols showing hydromorphic properties within 50 cm of the surface, Other Podzols having a B horizon in which a subhorizon contains dispersed organic matter and lacks sufficient free iron to turn redder on ignition, Other Podzols in which the ratio of percentage of free iron to percentage of carbon is 6 or more in all subhorizons of the B horizon, Other Podzols lacking or having only a thin (2 cm or less) and discontinuous albic E horizon; lacking a subhorizon within the B horizon which is visibly more enriched with carbon.

Policy aim at keeping land productivity will need to focus to reduce low and moderate soil erosion through terracing, inter-cropping, contour farming, strip cropping, conservation tillage, mulching and biological stabilizers based on their slope range, soil type and land use type. Whereas the rest low and moderate soil erosion risk classes account 24.7% and 5.07%, respectively (Table8). objective of this paper is to quantify and map an estimated soil loss by Greyzems showing hydromorphic properties within 5 cm of the surface. 0000003545 00000 n EurLex-2 The current finding also in consistence with the finding of Tessema (2011), who reported the annual Soil loss for Dire Dam Watershed from 0.00 to 263.25 ton/ha/year, Amsalu and Mengaw(2014), reported the annual soil loss in Jabi Tehinan Woreda ranges from nearly 0 in south and central parts of the area to 504.6 ton/ha/year in steeply sloping mountainous areas of the north and north-eastern parts of the catchments. Aside from this, the trees produces a milky substance, which is used for ink, for the purpose of writing charms, to be worn on any part of the body as a cure for those possessed by evil spirits, and to prevent their entering those who are not previously tormented with them. The milk of the genwarar was also used in the treatment of lingering sickness. A total of 456,415.60 ton of soil has been lost annually (Fig. (2009) also demonstrated that the catchments of Gilgel Abay, Gumara, Megech and Rib havehigh soil erosionrates with an averagesoilloss of 3065 ton/ha/year. 0 0 0 556 556 500 556 556 278 556 556 222 222 500 222 833 22 sub-watershed classes (A, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, T, U, V, W, Y) falls under low erosion severity classes (15 ton/ha/year). Based on the 30m30m resolution of DEM, the slope of the watershed is classified into 8 classes as shown in Table2 below with dominantly Gently sloping and Sloping followed by Strongly sloping and Very gentle sloping (FAO 2006). The fifth soil group is lithosols found primarily in the Denakil Plain. CHERNOZEMS (C)Other soils having a mollic A horizon with a moist chroma of 2 or less to a depth of at least IS cm; having one or more of the following: a calcic or a gypsic horizon, or concentrations of soft powdery lime within 125 cm of the surface when the weighted average textural class is coarse, within 90 cm for medium textures, within 75 cm for fine textures. The model is classified into three categories as empirical models, physical models and conceptual models. Quantitatively, an estimated annual soil loss in Jabi Tehinan Woreda ranges from nearly 0 in south and central parts of the area to 504.6 .

Moderate soil loss was estimated from pellic vertisols followed by Lithosols. Uniquely Ethiopian and among the most endangered species are the walia ibex of the Simien Mountains, the mountain nyala (a kind of antelope), and the Simien jackal. 1.1 and to Lorenzo Orioli for the information and photos of the Sanetti Plain. Planosols having permafrost within 200 cm of the surface, Other Planosols having more than 6 percent sodium in the exchange complex of the slowly permeable horizon, Other Planosols having a mollic A horizon or a eutric histic H horizon, Other Planosols having an umbric A horizon or a dystric histic H horizon, Other Planosols having a base saturation of less than 50 percent (by NH4OAc) in at least a part of the slowly permeable horizon within 125 cm of the surface. Soils developed over the lava deposits are mainly lithosols, while regosols are predominant on the Quaternary and pre-Cretaceous basinal deposits. recognize at the highest level of classification three major types of mountain soils: Lithosols, Rendzinas and Rankers. These outliers are part of the Day Forest and Mabla Mountains above 1,100 m in Djibouti.

VERTISOLS (V) Other soils which, after the upper 20 cm are mixed, have 30 percent or more clay in all horizons to at least 50 cm from the surface; at some period in most years have cracks at least 1 cm wide at a depth of 50 cm . >> Nitosols develop on gently sloping ground.

Birds include the endemic Archer's lark (Heteromirafra archeri).[2]. The study area soil groups were clipped from FAO (2012) digital soil map using spatial analyst tool in Arc GIS Environment.

Based on the finding, the following points should be recommended, The Moderate and Low soil erosion severity areas should be managed through terracing, inter-cropping, contour farming, strip cropping, conservation tillage, mulching and biological stabilizers based on their slope range, soil type and land use type. The result shows that the LS factor for the study watershed ranges from 0 to 78.48. Smaller towns include the former Afar Region capital of Asaita in Ethiopia and smaller ports along the coast such as Tadjoura in Djibouti and Zeila in Somalia.
