Abstract: Despite the vital importance of reliable data sets on the current effect of seasonal rainfall variability on water resources in Lake Mutanda catchment of southwestern Uganda, little is known about the status of this phenomenon. Lake Mutanda and its catchment provide water for domestic use, and irrigation. This study was aimed to assess the effects of seasonal rainfall variability on physicochemical and bacteriological water quality of Lake Mutanda and its catchments, and to suggest...
Abstract: Soil Organic carbon (SOC) is vital to the soil’s ecosystem functioning as well as improving soil fertility. Slight variation in C in the soil has significant potential to be either a source of CO2 in the atmosphere or a sink to be stored in the form of soil organic matter. Location-specific information on soil organic carbon (SOC) helps to identify potential sources and sinks of carbon. However, modeling SOC spatiotemporal changes was challenging due to lack of data to represent ...
Abstract: The adverse impact of climate change on agricultural production and productivity is increasing over time in Ethiopia. Smallholder farmers are the most vulnerable group of the society to the effects of climate change in this country since their livelihood depended on rainfed agriculture. This study was carried out to examine smallholder farmers’ vulnerability, perception, the choice of adaptation strategies, and institutional adaptive capacity of local institutions to climate chan...
Abstract: This study was conducted in the Liben woreda of Oromia regional state, southeastern Ethiopia in May at the end of main rainy season (March-May, 2020). The objective of this study was to determine vegetation structure and carbon stock potential of Guji zone rangelands under the three traditional rangeland management practices i.e., near the village, main grazing land and communal enclosure. A combination of stratification and systematic random sampling was applied to collect the rel...
Abstract: Hallaydeghe Wildlife Reserve is characterized by different land cover classes with semi-arid to arid climatic conditions. This study has analyzed the total carbon stocks and changes in the land cover during the 1986-2019 period of the study area. In addition, the effect of land cover type on carbon stocks under three different vegetation types namely woodland, grassland, and bushland has been evaluated. Screen digitization was performed on landsat images for the years 1986, 2003 an...
Abstract: Increasing heat stress threatens livestock production especially lactating dairy cows across the world. Therefore this study was conducted to evaluate the effect of heat stress on physiological parameters, adaptation and mitigation strategies of lactating Kereyu and Hararghe cattle breeds in Bordode District, Ethiopia. Purposive sampling technique was used to select study area and respondents and Bordode district was selected based on the availability of both Kereyu and Hararge cat...
Abstract: Faba bean is one of the most important pulse crops grown in Kersa Malima district both in terms of area coverage and volume of annual production. It is used as food and income for farmers, yet the major production limiting factors are sub-optimal seed handling practices, the use of inappropriate seed sources and varieties. Thus, this study is set with the objectives of assessing farmers’ production and seed handling practices, determine the effect of seed sources, variety and see...
Abstract: Climate-smart agriculture is expected to play a key role in tackling climate-related challenges to agricultural livelihoods and food systems. However, the implementation of these programs involving efficient, sustainable, and productivity-enhancing technologies and their adoption rate has remained low, particularly among small-scale farmers. The purpose of the study was to analyze determinants of climate-smart agricultural practices adoption in Toke Kutaye district, West Showa Zone...
Abstract: Soil moisture stress is one of the major problems that affect the growth and yield of sorghum crops during the main season in arid and semi-arid areas of East Hararghe. In such an area, integrated in-situ water conservation techniques and the application of mulching are very important. The study was conducted to evaluate the effect of tied ridge and mulching on sorghum growth, yield, yield-related components, and water use efficiency in Babile District East Ha-rarghe Zone which is ...
Abstract: Currently, more attention is being given to fertilizing the soil with micronutrients in many Sub-Saharan African countries including Ethiopia. This study was initiated to assess effects of boron fertilizer rates on selected soil properties, growth and growth parameters of sorghum (Sorghum bicolor L.) in Haramaya District, Eastern Hararghe Zone, Eastern Ethiopia. A preliminary survey and field observation were carried out to get general information about the landform, vegetation cov...
Abstract: Soil is one of the most important natural resources. However, detailed scientific knowledge and information are lacking on soil resources. Subsequently, this affects agricultural crop productivity and profitability if its potentials and limitations are not realized in the study area. The purpose of this study was to: (1) characterize and classify soils along toposequence; (2) analyze and map the spatial variability of soil fertility status, and (3) assess the spatial variability of...
Abstract: Soil erosion has become a globally challenging issue that poses a serious threat to agriculture and natural resources, particularly in developing countries like Ethiopia. Estimating the magnitude of soil loss and understanding the spatial distribution of erosion-prone areas is critical to plan and effectively implement soil conservation measures with limited resources. This study was conducted in Gununo watershed, where soil erosion is threatening the sustainability of agricultural...
Abstract: Characterization and classification of soil is the main source of information for precision agriculture, land use planning and management. For an efficient use of the limited land resources, site specific management recommendations based on site specific information are much required. Undulating topography, altitudinal differences and large variations in slope were characteristic features of the present study area (Dhengego subwatershed). The purpose of the present study was to cha...
Abstract: Social networks are an essential source of risk-sharing and capacity building strategies for responding the adverse effects of climate change. However, researches on climate change adaptation strategies not recognized the role of social networks. The current study aims to assess the role of social networks in facilitating smallholder farmers’ adaptation strategies to climate change in Woreilu district, South Wollo zone, Amhara national regional state, Ethiopia. More specifically,...
Abstract: Okra is one of indigenous genetic resource of Ethiopia, but only few studies were carried out to assess its variability and performance throughout the country. Therefore, it was necessary to continue the evaluation of available okra indigenous and introduced varieties to identify superior okra genotypes. Thus, this research was conducted to assess variation in growth and fruit yield of okra genotypes and genetic variability of indigenous and introduced okra genotypes for morpho-agr...
