To do so, an individual base cross-sectional data analysis along with the two stage sampling technique of both purposive and random sampling technique was undertaken. To analyze the data, the study employed two sets of models (logistic and the method of principal component analysis). The econometric results of the study indicates that determinants like lack of credit access, lack of financial planning, complexity of banking system, monthly expenditure on stimulants, sex, significantly and negatively affects households saving capacity, but monthly income, age, bank account holding experience, marital status, and occupation positively and significantly affects saving capacity. In similar fashion, determinants include improper government policy, weak institutional set up, complexity of banking system, distance in Km away from their home to financial institutions, and religion significantly and negatively affect the probability of households to be banked, on the other hand, sex of households, credit access, income, marital status, education and age positively and significantly affects the probability of households to be banked.

  • Rainfall Variability, Soils and Land Use Changes in the Highlands of Ethiopia
    THESIS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Rainfall variability, soils and land use changes in the highlands of Ethiopia Staffan Rosell DOCTORAL THESIS A148 UNIVERSITY OF GOTHENBURG DEPARTMENT OF EARTH SCIENCES GOTHENBURG, SWEDEN 2014 ISBN: 978-91-628-8843-5 ISSN: 1400-3813 Staffan Rosell Rainfall variability, soils and land use changes in the highlands of Ethiopia To Linda, Emma and Smilla A148 2014 ISBN: 978-91-628-8843-5 ISSN: 1400-3813 Internet-id: http://hdl.handle.net/2077/33656 Printed by Kompendiet, Göteborg Copyright © Staffan Rosell, 2014 Distribution: Department of Earth Sciences, University of Gothenburg, Sweden Abstract Most farmers in the Ethiopian highlands are dependent on rain-fed agriculture. The indigenous cereal tef is the most important crop for the farmers in the highlands. The central highland is an environmentally fragile area and a marginal area of Ethiopia with a recurring problem for the farmers to sustain an adequate agricultural production. The objectives of this thesis are; to analyse the rainfall change and rainfall variability in time and space and its impact on farmers’ potential to cultivate during the short rainy season Belg; to analyse the status of soil parameters and its consequences for farmers’ food production and; to analyse land-use changes and its consequences for the farmers dependent on agriculture. The geographical focus is on the central highlands and especially South Wollo. The rainfall analysis is based on daily rainfall data from 13 stations and covers the time period 1964-2012. Land use and land cover changes were analysed by interpretation of black and white aerial photographs from 1958 and colour satellite images from 2003 and 2013.

  • Periodic Monitoring Report Working 2016 Humanitarian Requirements Document – Ethiopia Group
    DRMTechnical Periodic Monitoring Report Working 2016 Humanitarian Requirements Document – Ethiopia Group Covering 1 Jan to 31 Dec 2016 Prepared by Clusters and NDRMC Introduction The El Niño global climactic event significantly affected the 2015 meher/summer rains on the heels of failed belg/ spring rains in 2015, driving food insecurity, malnutrition and serious water shortages in many parts of the country. The Government and humanitarian partners issued a joint 2016 Humanitarian Requirements Document (HRD) in December 2015 requesting US$1.4 billion to assist 10.2 million people with food, health and nutrition, water, agriculture, shelter and non-food items, protection and emergency education responses. Following the delay and erratic performance of the belg/spring rains in 2016, a Prioritization Statement was issued in May 2016 with updated humanitarian requirements in nutrition (MAM), agriculture, shelter and non-food items and education.The Mid-Year Review of the HRD identified 9.7 million beneficiaries and updated the funding requirements to $1.2 billion. The 2016 HRD is 69 per cent funded, with contributions of $1.08 billion from international donors and the Government of Ethiopia (including carry-over resources from 2015). Under the leadership of the Government of Ethiopia delivery of life-saving and life- sustaining humanitarian assistance continues across the sectors. However, effective humanitarian response was challenged by shortage of resources, limited logistical capacities and associated delays, and weak real-time information management. This Periodic Monitoring Report (PMR) provides a summary of the cluster financial inputs against outputs and achievements against cluster objectives using secured funding since the launch of the 2016 HRD.

  • Community Perception and Indigenous Adaptive Response to Climate Variability at Tehuledere Woreda, South Wollo
    Engineering International, Volume 1, No 2 (2013) Community Perception and Indigenous Adaptive Response to Climate Variability at Tehuledere Woreda, South Wollo Mohammed Seid Arbaminch University, Arbaminch , Ethiopia ABSTRACT Climate variability and extreme events have wide range economic, social and environmental impacts. In adaptation of these impacts, it is very important to assess and change the perception and awareness level of local community to climate variability and adaptation responses. Assessing the indigenous adaptation mechanisms and adaptation capacity is the integral part in addressing the adverse consequences of climate variability. There was no study, which assessed the adaptation to climate variability with integrating community perception in the study area. Thus, this study was aimed to fill this gap. The study has shown that, majority of participants were observed the existence of climate variability and indicators, But significant number of participants failed to perceive the causes of the variability. The effects of climate variability in the study area are land degradation, deforestation, decline of crop production, death of livestock, loss of grazing land, and destruction of infrastructures. The local communities have own adaptation methods, which include, production of different crops, planting of special variety crops, using of natural and chemical fertilizers, irrigation farming, planting of trees, and soil conservation. Adjusting the production season with the variability of climate is other cope up mechanism of farmers. The participants had problems with materials, financial and training supports from NGOs and governments. Key words: climate variability, community perception, adaptation BACK GROUND OF THE STUDY The United Nations Environment Programme (UNEP) report has shown that, many of the continental regions have experienced a sharp seasonal and annual rainfall variation and temperature variation plus with extreme events (flood, storms and drought).

Po box 79 *[email protected] Abstract This study investigates the response of Lake Hayq water level change over the period of 1972 to 2012. The purpose of this study was to show the water level change of Lake Hayq and the management practices for this change. The water level change of Lake Hayq was assessed by examining the water balance of the lake. Precipitation, runoff from the watershed area, evaporation and surface outflow from the lake are the major components of water balance of Lake Hayq. Penman’s combined energy balance and mass transfer approach formula was used to calculate annual evaporation rate of the lake. The resultant of water balance of the lake Hayq show that annually 0.9×10 6 m3 of water misplaced from the lake. The width of the isthmus of Lake Hayq has increased from 33 meter, to 108 meter and 163 meter in the years 1972, 1986 and 2012 respectively. As such, any fluctuations in the area and the level of the lake can be imposed by both natural and anthropogenic forces.
