ANALYSIS OF CLIMATE CHANGE AND VARIABILITY ON MAIZE (Zea mays L.) AND WHEAT (Triticum aestivum L.) PRODUCTION AND FARMERS’ ADAPTATION OPTIONS IN SORO DISTRICT, HADIYA ZONE, SOUTHERN ETHIOPIA

Abstract: Crop production is susceptible to weather and hence directly responsive to climate change, resulting in decline in yield and leads to food insecurity. This study was conducted in Soro district, Hadiya zone of southern Ethiopia to analyze climate change and variability on maize and wheat production and assess adaptation options. The primary data were collected by using household survey, focus group discussions, semi-structured interviews and field observation. The observed daily cli...

CLIMATE VARIABILITY, IMPACTS ON MAIZE (Zea mays L.) YIELD, AND SMALL HOLDER FARMERS’ PERCEPTION AND ADAPTATION STRATEGIES IN WEST BADAWACHO DISTRICT OF HADIYA ZONE, SOUTHERN ETHIOPIA

Abstract: Climate variability affects crop productivity at both global and local scales, and adaptation of agricultural practices against this variability helps to translate perception of the farmers to decision-making process. This study was initiated to analyze climate variability, examine its effect on maize productivity, and assess perception and adaptation strategies of smallholder farmers to climate variability in West Badawacho District. Climate and crop data from 2000-2019 were colle...

IMPACT OF CLIMATE VARIABILITY ON HOUSEHOLD FOOD SECURITY IN CHIRO DISTRICT, WEST HARARGHE ZONE, OROMIA REGION, ETHIOPIA

Abstract: Climate variability is depleting assets and adversely affecting food security of smallholders of rainfall dependent livelihoods, and it affects crop production and price due toincrease in average temperature and rainfall variability. This study was undertaken in Chiro district to analyze impact of climate variability on household food security in Chiro district. Data on rainfall/temperature and crop production were obtained from National Meteorological Agency and Chiro District Agr...

GENERATION RATE AND PHYSICO-CHEMICAL CHARACTERIZATION OF HOUSEHOLD SOLID WASTE IN MORSITO TOWN, HADIYA ZONE, SOUTHERN ETHIOPIA

Abstract: Rapid population growth and expanding urbanization have caused a dramatic increase in type and volume of household solid waste generated in many towns of the country including Morsito town. Most of this solid waste is illegally dumped in open site. The objective of this study was to determine the generation rate and characterize selected physicochemical properties of household solid waste in Morsito Town. A total of 131 households were randomly selected from purposively selected 2 ...

IMPACTS OF Prosopis spp. ON ENVIRONMENT AND LIVELIHOODS IN EAST AFRICA: EVIDENCE FROM ETHIOPIA AND KENYA

Abstract: Most invasive alien species reengineer the host ecosystem by altering its structure and functioning so that some new ecosystem services are added and, at the same time, some existing ecosystem services are lost. Prosopis, a woody invasive tree, was intentionally introduced in dry lands of east Africa for its environmental and economic benefits. However, some 40 years later, it escaped from plantations and has invaded significant. This study investigates impacts of Prosopis on the r...

DETERMINANTS OF ADOPTION OF SOIL AND WATER CONSERVATION MEASURES AND PARTICIPATION OF FARMERS IN WATERSHED DEVELOPMENT IN WEST HARARGHE ZONE: THE CASE OF HABRO DISTRICT

Abstract: Land degradation is one of the basic problems facing farmers in the Ethiopian highlands and this limits their ability to increase agricultural production and reduce poverty and food insecurity. Even though various soil and water conservation programs and a number of soil and water conservation were introduced to combat land degradation through the ministry of agriculture, on-and-off farm use of these practices remains below expectations in many degraded areas of the highlands of Et...

ANALYSIS OF MALT BARLEY VALUE CHAIN: THE CASE OF ANGOLALLA TERA WOREDA OF NORTH SHEWA ZONE, AMHARA REGION, ETHIOPIA

Abstract: This study analyzed the malt barley value chain in Angolalla Tera Woreda, North Shewa Zone of Amhara Region. The study used cross sectional data collected from 120 farm households selected through two-stage sampling techniques, 22 traders, 2 processors, 1 union and 4 cooperatives. Malt barley value chain actors in the study area include input suppliers, producers, cooperatives, union, wholesalers, processors, retailers, and consumers. The malt barley market concentration ratio in t...

THE LIVELIHOOD EARLY ASSESSMENT AND PROTECTION AS A TOOL IN CLIMATE MONITORING AND ESTIMATION OF MEHER SEASON MAIZE AND TEFF PRODUCTION: A CASE STUDY IN ADA’A AND AMBO WOREDAS, CENTRAL ETHIOP

Abstract: This research was conducted to test the business potential of the decision support tool known as Livelihood Early Assessment and Protection (LEAP). The initial intension with LEAP development was to monitor the climate and crops through growing season for food security analyses in Ethiopia. In this study the performance of the tool was tested over agriculturally high productive areas of Ada’a and Ambo Zuria woredas in central Ethiopia, using key indicator data sets the satellite ...

CLIMATE VARIABILITY AND ITS IMPACT ON WHEAT (Triticum aestivum L.) YIELD IN SELECTED WOREDAS OF SOUTH EASTERN ZONE OF TIGRAY, NORTHERN ETHIOPIA

Abstract: In Ethiopia in general and the study region in particular, where vulnerability to climate change and variability is high studying the impact of climate change at a local scale is critical for designing appropriate strategies for adaptive capacity. This study was conducted in four Woredas of Tigray Region namely Hintalo Wejerat, Degua Tembien, Enderta and Seharti Samre to examine whether observed climate variables revealed significant change and to assess the impact of future climat...

ASSESSMENT OF THE EFFECTIVENESS OF ECOSYSTEM-BASED ADAPTATION FOR LOCAL COMMUNITIES LIVING AROUND LAKE KIBARE RIPARIAN ZONE, RWANDA

Abstract: Local communities’ adaptation to climate change requires measures that simultaneously reduce poverty, protect or restore biodiversity and ecosystem services, and remove atmospheric greenhouse gases. Ecosystem-based Adaptation (EbA) involves measures for climate change mitigation and adaptation that aim to strengthen the resilience of local communities vulnerable to climate change effects. It combines measures to achieve these multiple outcomes and is particularly relevant to deve...

ASSESSING CLIMATE CHANGE IMPACTS ON WHEAT [TRITICUM AESTIVUM (L.)] AND BARLEY [HORDEUM VULGARE (L.)] PRODUCTION AND POTENTIAL ADAPTATION OPTIONS IN CENTRAL ETHIOPIA

Abstract: Climate change affects crop productivity in most parts of the world, particularly in Sub-Saharan Africa. This challenge is expected as a major threat to crop production in central Ethiopia. The major purpose of the study was to assess the current and future impacts of climate change on wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) production in central Ethiopia and identify adaptation options. In order to achieve these objectives, the study combined climate analysis,...

EFFECT OF SLOPE GRADIENT ON VEGETATION AND SOIL ATTRIBUTES OF GARA ADES PROTECTED VEGETATION IN WESTERN HARARGHE ZONE OF OROMIA REGION, ETHIOPIA

Abstract: The study was conducted at Gara Ades protected vegetation of Doba woreda, Western Hararghe Zone, Ethiopia; from October to December 2017 with the objective of analysing the woody vegetation structure, diversity and regeneration status, as well as soil status potentials under three slope gradient classes. Primarily, slope classes were set purposively; where lower slope class was (LSC: 10 - 20 %) and upper slope class was (USC: >20 - 0.05) different in the LSC, MSC and USC which is p...

FARMERS’ PERCEPTION AND ADAPTATION STRATEGIES TO CLIMATE CHANGE: THE CASE OF WOREILLU DISTRICT OF AMHARA REGION, NORTHEASTERN ETHIOPIA

Abstract: Climate change has adversely affected the livelihoods of people in developing countries where a large proportion of the population is heavily dependent on agriculture. Severe and repeated rise in temperature and rainfall failures caused loss of crops and livestock which resulted in food insecurity in Ethiopia. This study aims to investigate farmers’ perception and adaptation strategies to climate change in Woreillu District. Both qualitative and quantitative data obtained using p...
