Abstract:
Woodlands, which are part of the landscape and an important source of livelihood for smallholders living in the environmentally vulnerable Central Rift Valley (CRV) of Ethiopia, are experiencing rapid changes. Detecting and monitoring these changes is essential for better management of the resources and the benefits they provide to people. The study used a combination of both quantitative and qualitative methods to analyze the extent and pattern of woodland cover changes from 1973 to 2013. Pixel-based supervised image classification with maximum likelihood classification algorithm was used for land cover classification and change detection analyses. Local peoples’ perceptions were used to explain the patterns of change and their possible reasons. Four major land cover classes were identified, with an overall accuracy of 88.3% and a Kappa statistic of 0.81 for the latest image. The analysis revealed a major land cover reversal, where woodland (92.4%) was the dominant land cover in 1973, while it was agriculture (44.7%) in 2013. A rapid reduction in woodland (54%) and forest (99%) covers took place between 1973 and 2013, with the majority of the conversions being made during the government transition period (1973 to 1986). Agriculture (3878%) and grassland (11,117%) increased tremendously during the 40-year period at the expense of woodlands and forests. Bare land increased moderately (40%). Thus, woodlands are under increasing pressure from other land uses, particularly agriculture, and declining faster. If the current trends of land cover change remain unabated it is likely that woodlands will disappear from the landscape of the area in the near future. Therefore, better forest policy and implementation tools, as well as better woodland management strategies and practices, need to be in place for woodlands to continue providing vital ecosystem goods and services to the local people, as well as to the environment.

Abstract.Cutaneous leishmaniasis (CL) is a major public health problem in Ethiopia. The disease is endemic in Ochollo, a village in southern Ethiopia, but there are no reports of CL in the wider area, although it is ecologically very similar. We conducted a rapid assessment survey in the South Ethiopian Rift Valley and found 100 parasitologically confirmed CL cases in 38 villages not reported endemic for CL. Approximately half of the cases were children (57%), and most lesions occurred on the face (78%) and were older than 6 months (77%). Only 2% of the people was aware of the mode of transmission, and 9% sought modern treatment at a hospital. These preliminary data indicate that CL is much more widespread than previously reported and that the disease might have a large psychosocial impact. Hence, this study calls for larger surveys across the Ethiopian highlands. Additionally, health education and treatment capacity need to be implemented.

Abstract:
Hot pepper (Capsicum annum L.) is one of the important cash crops to Ethiopian smallholder farmers and an important agricultural commodity which contribute to export earnings. In Ethiopia, this high value crop is constrained by powdery mildew, Phytophthora leaf blight, Fusarium wilt, bacterial leaf spot, bacterial wilt, bacterial soft rot and pepper motile virus. Among this diseases, wilt disease caused by Fusarium oxysporum f.sp. capsici (FOC) is one of the major pathogen that constrained production and productivity of hot pepper in Ethiopia mainly the Central Rift valley. In Ethiopia, hot pepper fusarium wilt is reported in all production regions in different magnitude. The highest wilt incidence due to fusarium is 90% in some Farmers association of Alaba districts in South Nation Nationalities and peoples of Ethiopia. The economic yield losses due to Fusarium wilt has been estimated at 68 to 71%. Infection and disease development in Fusarium wilt is favored by warm soil temperature, low soil moisture, susceptible host, virulent pathogen and 5.0 to 6.0 pH levels; are some of epidemic factors. Fusarium is reproduced by sexually by teleomorphs and asexually by microconidia, macroconidia and chlamydospore. From the Central rift valley of Ethiopia, 49 FOC isolates were identified based on micro and macroscopic characteristics and the isolate having pink colony color, 3-5 septa forming conidia on potato dextrose agar, perform the most pathogenic ability to Mareko Fana Variety. This pathogen has an over wintering stage called chlamydospore which can exist in the soil for more than ten years without the host. Hot pepper fusarium wilt can be managed by host resistance, biological agent, botanicals and fungicide. In Ethiopia, pepper screening for resistant source, in vitro evaluation of bioagents and fungicides were done. In this review attempt has been made to summarize relevant scientific studies on this economically important crop, hot pepper fusarium wilt and associated factors in Ethiopia as well as its different disease management options, challenges and future prospects.

Abstract:
>Magister Scientiae - MSc
The class Actinobacteria consists of a heterogeneous group of filamentous, Gram-positive bacteria that colonise most terrestrial and aquatic environments. The industrial and biotechnological importance of the secondary metabolites produced by members of this class has propelled it into the forefront of metagenomics studies. The Ethiopian Rift Valley lakes are characterized by several physical extremes, making it a polyextremophilic environment and a possible untapped source of novel actinobacterial species. The aims of the current study were to identify and compare the eubacterial diversity between three geographically divided soda lakes within the ERV focusing on the actinobacterial subpopulation. This was done by means of a culture-dependent (classical culturing) and culture-independent (DGGE and ARDRA) approach. The results indicate that the eubacterial 16S rRNA gene libraries were similar in composition with a predominance of α-Proteobacteria and Firmicutes in all three lakes. Conversely, the actinobacterial 16S rRNA gene libraries were significantly different and could be used to distinguish between sites. The actinobacterial OTUs detected belonged to both the Rubrobacterales and Actinomycetales orders with members of the genus Arthrobacter being found in all three lakes. Geochemical properties were significantly different between the lakes, although more than one property attributed to the variance between community compositions. The diversity detected in the culture-based study differed significantly and all isolates belonged to the genus Streptomyces. Two novel strains were characterized by means of phylogenetic (16S rRNA gene sequence), physiological, morphological and biochemical analyses. Both novel isolates were capable of growing under "extreme" conditions- pH 12, 10% NaCl and 45°C. Partial enzyme characterization revealed that both strains produced xylanase enzymes that were active at pH 6.5 and 8.5 with an increase in activity up to 45°C. The results obtained revealed a previously undetected diversity of actinobacteria in the Ethiopian Rift Valley with a potentially novel subpopulation adapted to haloalkaline conditions. The low 16S rRNA sequence similarity of a substantial proportion of the libraries suggests that culture-based isolation may play a vital role in deciphering the community fingerprint.

Abstract:
Fluoride is present in all type of water sources, but levels beyond the current World Health Organization guideline of 1.5 mg/L can be very harmful for people’s health. Due to the volcanic nature of rocks in the Ethiopian Rift Valley, groundwater is contaminated with fluoride, and studies have even recorded levels up to 26 mg/L. These excessive levels are affecting more than 14 million women and children in Ethiopia. Providing population with safe and clean water could help to achieve the Sustainable Development Goal 6 (i.e. Ensure availability and sustainable management of water and sanitation for all) from the United Nations. Membrane distillation systems have been extensively tested in literature, proving to be effective in removing fluoride, even at higher concentration levels (500 mg/L). Membrane distillation is a heat driven system that works under feed water temperatures below 100 ºC. Renewable energy sources such as geothermal, solar or biomass can be used to provide that heat. This report evaluates techno-economically different technologies using TRNSYS: flat plate solar collectors, evacuated tube solar collectors and biogas from animal dung, as heat source for the membrane distillation unit. The size of the hypothetical installations was optimized to cover the demand of 30 households. Several indicators were calculated to compare the different technologies: specific energy demand, water production, and efficiency of the systems. Investment costs and operation and management costs were considered to calculate total costs and payback period of the different installations. The results show that the best techno-economic option to be installed is a hybrid model that includes a combined heat and power unit powered by biogas and evacuated tube collectors, as can meet the demand with one membrane distillation unit and also supplies electricity and biogas for cooking. However, depending on the specific location, the availability of solar radiation and manure can vary, and consequently the best option will change. In case the existence of livestock is limited, three membrane distillation units coupled with 85 m2 of evacuated tube collectors can cover the demand. If the availability of sun is limited one membrane unit coupled with a standalone biogas unit can be considered. Flat plate collectors are never the best option, as they require the biggest investment cost. Nevertheless, the existence of local manufacturers can decrease the costs.
Fluor finns i alla typer av vattenkällor, men koncentrationer som ligger över nuvarande Världshälsoorganisationens riktlinjer (max 1.5 mg/L) kan vara skadlig för hälsan. Grundvatten vid Ethiopian Rift Valley innehåller höga fluorhalter på grund av geologiska orsaker, och studier har visat nivåer upp till 26 mg/L. Sådana höga halter påverkar över 14 millioner Etiopiska kvinnor och barn negativt. Att tillgodose befolkningen med säkert och rent dricksvatten skulle bidra till uppfyllelsen av FN:s Hållbarhetsmål nr 6 (Säkerställa tillgång till och hållbar vatten- och sanitetsförvaltning för alla). Membrandestillering har testats grundligt och har visat sig att vara en effektiv teknik för fluorseparering även vid höga halter (över 500 mg/L). Membrandestillering ar en värmedriven process som utnyttjar källor under 100 ºC. Värmen kan fås från förnybara energikällor som geotermisk energi, solenergi och biobränsle. Denna rapport presenterar en tekno-ekonomisk utvärdering av olika teknik med TRNSYS: plan solfångare, vakuumrörsolfångare och biogas från boskapsgödsel.  Storleken hos de undersökta systemen optimerades för att täcka behovet av 30 hushåll. Flera indikatorer beräknades för att jämföra de olika teknikerna: specifika energibehov, vattenproduktion och systemens verkningsgrader. Investeringskostnaderna och drift- och underhållskostnaderna låg som grund för att bestämma bruttokostnaderna och återbetalningstiderna av de olika systemen. Resultaten visar att den mest fördelaktiga konfigurationen består av en hybrid av biogas och vakuumrörsolfångare. Detta system tillgodoser vattenbehovet och dessutom levererar el och gas för matlagning. Tillgången till solenergi och gödsel spelar en viktig roll när det gäller systemvalet. Om tillgång till gödsel är begränsad kan efterfrågan täcks genom tre membrandestilleringsenheter kopplade till 85 m2 vakuumrörsolfångare. Däremot om solenergin är begränsad kan ett system med en membrandestilleringsenhet kopplade till en biogasanläggning tillgodose vattenbehovet. Plan solfångare är aldrig ett bra alternativ eftersom de kräver höga investeringskostnader. Tillgång till lokal tillverkning kan dock minska sådana kostnader.

Abstract:
Middle Awash basin, located in the complex volcanic centre of the Ethiopian Rift valley, is one of the drought prone areas marked by considerable water supply problems. Due to lack of surface waters, groundwater remains the sole resource supplying water for domestic and livestock. However, its effective use has been hampered due to the complex aquifer system of this basin. In this study, multidisciplinary method has been applied to characterize the hydrogeological system of this complex volcanic basin. The combined results from datasets show two distinct aquifer systems linked to geology and physiographic location. The Ca-alkaline rocks like basalt, ignimbrite, and trachybasalt form aquifers in the mountain regions whereas the Na-alkalne rocks which include scoria, pumice, tuff, and volcanoclastics are main aquifers in rift floor. Ground waters circulating in the highland areas are slightly mineralized and are Ca-Na-HCO3 type. On the other hand, ground waters in the rift floor are Na-HCO3-Cl types and are highly mineralized as well as contain high load of fluoride much higher than the permitted standard. Rivers hydrograph, hydrochemistry, environmental isotope, and 2D tomography are in good agreement showing fast percolation of rainfall and strong interaction between surface waters and ground waters. Result from numerical groundwater flow modeling further indicates the strong interaction between groundwater and surface waters in the form of losing and gaining
Le bassin central d'Awash, situé dans le centre volcanique complexe de la Vallée du Rift éthiopien, est un des secteurs les plus touchés par la sécheresse et par des problèmes considérables d'approvisionnement en eau. En raison du manque d'eau de surface, l'eau souterraine reste la ressource unique fournissant l'eau potable. Cependant, l'exploitation effective de l'eau souterraine s'est heurtée à la méconnaissance du système hydrogéologique complexe de ce bassin. Dans cette étude, une approche pluridisciplinaire a été mise en oeuvre pour caractériser l'hydrogéologie de ce bassin volcanique complexe. Les résultats couplés de l'ensemble des données montrent deux systèmes aquifères distincts liés à la géologie et à la localisation physiographique. Les roches Ca-alcalines comme le basalte, l'ignimbrite et le trachybasalte forment des aquifères dans les régions de montagne tandis que les roches Na-alcalines qui incluent les scories, la pierre ponce, les tufs et les volcanoclastiques constituent les principaux aquifères au niveau du plancher du rift. Les eaux souterraines circulant dans les secteurs montagneux sont légèrement minéralisées et sont de type Ca-Na-HCO3. Par contre, les eaux souterraines du plancher du rift sont de type Na-HCO3-Cl, sont fortement minéralisées et contiennent une charge en fluorure beaucoup plus élevée que les normes permises. Les résultats de diverses approches (hydrogrammes des fleuves, hydrochimie, isotopes environnementaux et tomographie 2D) sont concordants et montrent une percolation rapide des eaux de pluie et une forte interaction entre les eaux de surface et les eaux souterraines. Les résultats de modélisation numérique confirment la forte interaction eau souterraine - eaux de surface

Abstract:
Abstract This research work attempts to map out the stratigraphic sequence of the Kerio Valley Basin using magnetic, gravity and seismic data sets. Regional gravity data consisting of isotactic, free-air and Bouguer anomaly grids were obtained from the International Gravity Bureau (BGI). Magnetic data sets were sourced from the Earth Magnetic Anomaly grid (EMAG2). The seismic reflection data was acquired in 1989 using a vibrating source shot into inline geophones. Gravity Isostacy data shows low gravity anomalies that depict a deeper basement. Magnetic tilt and seismic profiles show sediment thickness of 2.5-3.5 Km above the basement. The Kerio Valley Basin towards the western side is underlain by a deeper basement which are overlain by succession of sandstones/shales and volcanoes. At the very top are the mid Miocene phonolites (Uasin Gishu) underlain by mid Miocene sandstones/shales (Tambach Formation). There are high gravity anomalies in the western and southern parts of the basin with the sedimentation being constrained by two normal faults. The Kerio Valley Basin is bounded to the west by the North-South easterly dipping fault system. Gravity data was significantly of help in delineating the basement, scanning the lithosphere and the upper mantle according to the relative densities. The basement rocks as well as the upper cover of volcanoes have distinctively higher densities than the infilled sedimentary sections within the basin. From the seismic profiles, the frequency of the shaley rocks and compact sandstones increases with depths. The western side of the basin is characterized by the absence of reflections and relatively higher frequency content. The termination of reflectors and the westward dip of reflectors represent a fault (Elgeyo fault). The reflectors dip towards the west, marking the basin as an asymmetrical syncline, indicating that the extension was towards the east. The basin floor is characterized by a nearly vertical fault which runs parallel to the Elgeyo fault. The seismic reflectors show marked discontinuities which may be due to lava flows. The deepest reflector shows deep sedimentation in the basin and is in reasonable agreement with basement depths delineated from potential methods (gravity and magnetic). Basement rocks are deeper at the top of the uplift footwall of the Elgeyo Escarpment. The sediments are likely of a thickness of about 800 M which is an interbed of sandstones and shales above the basement.
