    Application of GIS and Remote Sensing in Mapping Wildlife Land Suitability for Mountain Nyala Species at Bale Mountains National Park, Ethiopia
    (Addis Ababa University, 2014-06) Fayera, Zerihun; Woldetsadik, Muluneh (PhD)
    The Bale Mountains are the largest remaining alpine habitats, whereby Bale Mountain National Park is found in the African continent. The Bale Mountain National Park was first proposed to help protect the diverse and abundant wildlife, particularly the Mountain Nyalas and Red Foxes that are endemic to the world wide. Even though proposals to set up this conservation area have been planned since 1973, the area proposed is very large and the available infrastructure is completely inadequate to manage it effectively and this led to extensive wildlife habitat fragmentations. Thus, the intension of this study is to assess the habitat suitability range of Mountain Nyala species in Bale Mountains National park so as to aid an effort for utilization and conservation as well as to provide a background information to guide park managers in making appropriate decision using GIS and remote sensing technologies. By implementing GIS spatial analyst techniques, the study was attempted to identify potential habitat for Mountain Nyala (one of wild life species) at BMNP. Eight datasets i.e. vegetation types, soil types, topographic factor (elevation and slope), climate factor (temperature), proximity factors (distance to settlement, road and river) have been employed to map out wildlife land suitability corridor for Mountain Nyala specie. The weights were calculated using IDRISI32 Multi-criteria Evaluation in weight module pair-wise comparison method. Then weighted factors maps were integrated using weighted overlay analysis to run the wildlife corridor suitability model. Finally wildlife corridor map for Nyala was produced. In general, the result of the land suitability analysis for selected species shown five classes of suitability; from the total land of the study area 137.5 km2 (% 5.96) was highly suitable, 395.6 km2 (% 17.14) was moderately suitable, 561.8 km2 (% 24.34) was marginally suitable, 501.6 km2 (% 21.73) was currently not suitable, and 711.5km2(% 30.83) was permanently not suitable areas. The suitability analysis shows that 1091.5km2(47.5%) of the study area is habitat suitable range for Mountain Nyala species where as 1213.1km2 (52.5%) of the study area are currently and permanently not suitable areas respectively.

    Assessement of Urban Agriculture in Addis Ababa; The Case of Mushroom Cultivation
    (Addis Ababa University, 2015-05) Gebretsadkan, Gebrelibanos; Woldetsadik, Muluneh (PhD)
    This research paper was studied on urban agriculture with particular emphasis on assessment of urban mushroom farming in Addis Ababa. The general objective of the study is to identify some of the major problems and constraint faced the urban mushroom producers, investigates and explains the character and role of urban agriculture with emphasis on mushroom farming. It also tries to see the types of assistance needed and suggests possible solutions to the problems. The analysis of the study utilized both primary and secondary data. The primary data were collected through questionnaire survey, interviews and personal observations that covered 55 persons directly and indirectly involved in mushroom agriculture. The secondary data were collected from different libraries, document centres and offices. The study investigate lack of capital investment to start up, flying pests, diseases, high temperatures, lack of physical materials such as the production place, lack of training and experience, lack of awareness of the people due to lack of modern advertisement, lack of support from governments and other bodies as well as less concern of the government about the practice of mushroom farming makes them less productive. Mushrooms used as a food directly or indirectly, it also have a great culinary capability since it can protect many diseases and source of employment to all groups of the people (women, child, youths, old ages and disabilities), mushrooms can be cultivated 7 to 8 times per year on the same bedroom, its more productive and profitable

    The Impacts of Climate Change on Rural Livelihood and Their Adaptation Methods: the case of Alamata woreda, Southern Tigray
    (Addis Ababa University, 2011-06) Gebremedhn, Nigus; Woldetsadik, Muluneh (PhD)
    Climate change and variability is one of the greatest challenges facing the Ethiopian agrarians. Climate change has a drastic impact on agricultural output, with total crop failure and massive livestock deaths. Furthermore the capacity of the rural poor to cope with climate related shocks has declined due the increase frequency and intensity of droughts. This study looks on the impact of climate change on rural livelihood and their adaptation methods of Alamata woreda. The woreda or the study area is hotspot for the impact of climate change. Three tabias was selected by simple random sampling method and 131 persons were participated in the study. The general findings of the study shows that the climate of the woreda has show variability and in turn this climate change and variability has impact on the woredas livelihood sources like: crop production, cropping pattern, availability of long cycle crops, and availability of livestock feed and loss of livestock were the major ones. To minimize the impacts of climate change and variability the farmers of the woreda had adopted different coping strategies like; decrease on amount of meal, selling labor, food aid, selling livestock and other assets and eat less expensive foods. Beles feeding for livestock, migration, early maturing crop varieties, water and soil conservation, rehabilitation of gullies and area closure were long term adaptation practices applied by farmers and woreda office of agriculture. By considering the above facts the researcher recommends: there should collaboratively works of farmers and DA experts on rehabilitation of their environment. The woreda’s office of agricultural should encourage farmers to use drought resistant crop seeds with commercial fertilize, compost and soil moisture management practices. In addition there should be focus on planting fodder trees and beles around irrigation dykes and area closures

    The Problem of Housing in Hosanna Town: The Case of Addis Ketema Kifle Ketema
    (Addis Ababa University, 2014-06) Tesfaye, Solomon; Woldetsadik, Muluneh (PhD)
    One requirement of housing for human being is to provide shelter in order to provide shelter in order to shield from natural and social phenomena. The problem of housing is a worldwide problem and the problem of housing is more severe in less developing than developed countries. The study is to examine the extent and seriousness of the housing shortage and associated problems. Extensive survey of theoretical and empirical literature was made to support the paper with applicable and worthfull ideas. Primary data were also collected from the study area using both open ended and close ended questionnaires, structured interviews and by referring to documents and reports of the different governmental institutions. Single quantitative techniques are used to analyze the data collected. The study argues that the exacerbation of much of the existing housing problem lies in the failure of policy intervention to facilitate grounds for cooperation between concerned groups. Accordingly, it suggests the need for cooperation and partnership between major interest groups as available tool for future policy capable of taking the housing problem of Hosanna town. The need for future research is also indicated

    Suitable Solid Waste Disposal Site Selection Using Gis and Remotsensing Approach: A Case of Welkite Town, Ethiopia
    (Addis Ababa University, 2014-05) Beshir, Kumel; Woldetsadik, Muluneh (PhD)
    Solid waste management system is the most difficult task that many countries, both developing and developed, are facing. Landfill method is one of the easy and cheap management systems which are always needed for sustainable management of solid waste. The main objective of the study was to select landfill site for the town that is environmentally sound, socially acceptable and economically feasible in Welkite town. To achieve the objectives, the present study was conducted by integrating Geographic Information System and remote sensing for selecting suitable landfill sites. All the factor maps were reclassified and standardized in GIS environment followed by preparation of their suitability map. Analytical Hierarchy Processes pair-wise comparison module was used to derive weights for all factor parameters. Accordingly, 49.64km2(62.17%) of the study area is unsuitable, 22.16km2(27.75%) of the total study area is moderately suitable and 8.04km2(10.1%) is highly suitable for landfill. The finding of the study shows that 9 candidate landfill sites in relation to those evaluating criteria. Landfill site 2 which is located in Addis sub- town, is chosen as the most suitable site. Landfill sites 6 and 9 located in Gubre sub-town are the second and third most suitable sites respectively. Therefore, landfill sites 2, 6 and 9 are ranked from 1 to 3 based on their area and distance from the center and nearby settlements due to their minimum environmental and social negative effects compared to the other sites. In general, landfill site selection has been required appropriate consideration from stakeholders and other concerned bodies.
