Generation Rate and Physico-chemical Characterization of Municipal Solid Waste in Fonko Town of Analemo District, Hadiya Zone, Southern Ethiopia

Abstract: Solid waste, which is a consequence of day-to-day activity of human kind, needs to be managed properly. The improper management of the MSW is a major cause for water, air and soil pollution. Municipal solid wastes (MSW) generations and characterization of its composition is essential for proper management of municipal solid waste in the study area. This study aims to determine generation rate and physico-chemical characterization of Municipal Solid Waste in Fonko Town. In present s...

Impact of deforestation on rural livelihood in Shekila and Qallo Kebeles of Dewa-Chefa District, Oromia Zone, Amhara Regional State, Ethiopia

Abstract: Deforestation has significant negative impacts on the livelihood of the local community. The rate and extent of deforestation is much higher today than in the past. However, the impact of deforestation on community livelihood is not documented. Therefore, this study was aimed to address and fill the existing theoretical and practical research gap. That means by providing the necessary information about the impact of deforestation on rural livelihood. This research was carried out w...

PHYSICO-CHEMICAL CHARACTERSTICS AND HEAVY METALS CONCENTRATIONS OF DEBRE BIRHAN TANNERY WASTE WATER AND BERESSA RIVER WATER IN NORTH SHOA, ETHIOPIA

Abstract: Tannery Industries are one of the most highly polluting sectors in developing countries like Ethiopia. Debre Birhan Tannery Industry releases effluent that pollutes the nearby Beressa River. This study was characterized effluent discharged from Tannery Industry and Beressa River water. The (effluent and river water samples) were analyzed for various physicochemical properties like temperature, pH, Conductivity, Turbidity, Total dissolved solid, Chemical oxygen demand, Biological Ox...

SPECIES DIVERSITY AND USE OF HOMEGARDENS IN MISHA WOREDA, HADIYA ZONE OF THE SOUTHERN NATIONS NATIONALITIES AND PEOPLES REGIONAL STATE, ETHIOPIA

Abstract: Homegarden is an intensive land use system involving the deliberate management of multipurpose trees and shrubs grown in intimate association with herbaceous species with diverse use value. The aim of this study was to assess species diversity and use of the plant species in the homegardens including their seasonal variation in Misha Woreda, Hadiya Zone, of the Southern Nations, Nationalities and Peoples Regional State, Ethiopia. Four kebeles with distinct altitude were selected pu...

Status and Functions of Rainwater Harvesting Ponds and Constraints to their Sustainability in Meyu Muluke Woreda, Eastern Hararghe Zone, Oromia Region, Ethiopia

Abstract: Water scarcity is a critical issue for many developing countries in general and for those in the arid to semi-arid areas of the world in particular. It is a key challenge and a major constraint to economic and human development in the ASA areas of Ethiopia. To mitigate the threat from water scarcity, there have been extensive efforts and attention given towards rainwaterharvesting technologies because of its potential as a viable option to address the problem. This study focuses on...

Impacts of Selected Watershed Management Practices on Rehabilitation of Degraded Land and Farmers’ Perception in Dima Bite and Finchawa Micro-watersheds, North Shoa Zone, Ethiopia

Abstract: Watershed management practice was taken as the basic operational unit to rehabilitate the degraded land and improve agricultural productivity of land in Ethiopia. However, its impacts in rehabilitation of degraded land were rarely evaluated. This study was designed to assessed the impact of watershed management practices on woody plant composition, farmers’ perception and identify the factors that affect the adoption of soil and water conservation practices based on comparative a...

EFFECT OF IRRIGATION METHODS AND IRRIGATION LEVELS ON YIELD AND WATER PRODUCTIVITY OF ONION AT AWASH MELKASA, ETHIOPIA

Abstract: Water is scarce resource in Central Rift Valley of Ethiopia and is major limiting factor for crop production. Onion is one of the major economically important vegetable crops grown under irrigation in central rift valley. The field experiment was conducted at Melkasa agricultural research center during the off-season to identify irrigation method and irrigation application level that maximizes productivity of onion per unit of water consumed and enhanced onion crop production. The ...

HEAVY METAL STATUS OF MUNICIPAL SOLID WASTE AND SOIL AT KOSHE OPEN DUMPING SITE OF ASSELA TOWN ,OROMIA REGION, ETHIOPIA

Abstract: Dumping of heavy metals wastes has environmental impacts on soil and water at the nearby waste dump sites. The purposes of this study was to identify the sources and also status of selected heavy metals in municipal solid waste and soil at koshe open dumping site of Assela Town. For seven consecutive days metal wastes were manually separated from all wastes dumped at the site to identify the sources of heavy metals.Sources of the metals were categorized under three groups; househol...

PHYSICO-CHEMICAL CHARACTERIZATION OF KOMBOLCHA TANNERY EFFLUENT AND ITS IMPACT ON ABBA SHARO RIVER WATER DURING A DRY SEASON, SOUTH WOLLO, ETHIOPIA

Abstract: Kombolcha leather industry produces huge amounts of inorganic and organic wastes which pollute the adjacent environment including Abba Sharo River. This study was focused on characterizing the physic-chemical parameters of Kombolcha tannery effluent and evaluates its impact on the water quality of receiving Abba Sharo River water. Accordingly, two tannery effluent samples along wastewater channel at different distances have been taken and three river water samples were collected al...

DETERMINANTS OF HOUSEHOLDS RESILIENCE TO DROUGHT RELATED SHOCKS AND COPING STRATEGIES: THE CASE OF DARO LEBU WOREDA, OROMIA REGIONAL STATE, ETHIOIPA

Abstract: Drought is a common shock in Ethiopia affecting livelihoods of the community. The study area is one of areas in Ethiopia suffering from recurrent drought. The community lacks capacity to absorb shocks and recover back quickly after shock which determined by different factors.
