Abstract: downscaling projected temperature and rainfall in all time periods of the century (2020s ,2050s and 2080s),under two concentration pathways (RCP 4.5 and RCP 8.5). Similarly, DSSAT crop model was used to analyze the impacts of the projected climate change on the yields of Ejere and Natoli chickpea varieties and to evaluate adaptation options. Different planting dates were analyzed to identify best adaptation option. Simulations were done after calibrating and validating the crop mod...
Abstract: Understanding the influence rainfall variability on agricultural production is needed to cope with current and future changes in rainfall variables especially in countries that largely rely on rain fed agriculture. The objective of this study was to analysis rainfall variability, farmers’ perception and adaptation strategies in the Daro Lebu Woreda. To achieve this objective, historical climate data from 1995-2019 were obtained from Ethiopian National Metrological Agency. In addi...
Abstract: The issues of a social network, pluralism in the seed system, and adaptation to climate change are becoming more commanding in the tragedy of climate change and variability. Adaptation decisions are often based on interactions between people and their collective activities, which are mediated through informal networks from which resources may be derived and facilitate access to information needed for adaptation. The objective of this study was to analyze the role of social networks...
Abstract: Climate change and variability is increasingly being recognized as a critical challenge to pastoral production systems in the arid and semi-arid rangelands of Ethiopia. Pastoral communities in the Borana zone of Ethiopia have been changing and adapting their livelihoods to changing environmental conditions for centuries. The objective of this study was to assess the vulnerability of pastoralists and their adaptation strategies to climate change and variability in the rangeland of B...
Abstract: The study was conducted in Deder District of Obi forest, with the objectives of assessing the woody species diversity, composition and estimating of the carbon stock of the forest. A systematic sampling method was used to conduct the vegetation sampling. In order to collect vegetation data, a total of 36 quadrats, each with the size of 20 m x 20 m for tree, 5 m x 5 m for shrubs at an interval of 100 m, were laid along altitudinal variation. Aboveground biomass was estimated by usin...
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...
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 ...
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...
Abstract: Climate change is expected to alter the growing conditions of agricultural crops. With increasing surface temperature, future suitable areas for crop production will see an altitude shift. Such shift is an adaptation response of crops to climate change. However, in the study area there are a limited number of studies that have dealt with geographical shifts of crops caused by climate change. This study was conducted with the aim of assessing impacts of climate change on altitudinal...
Abstract: Climate change and land degradation adversely affect food security in sub-Saharan Africa (SSA). Smallholder farmers are the most affected. Therefore, it is imperative to identify technologies that boost resilience to climate change, and restore lands. Push-pull technology is among proposed solutions. This technology controls stem borers, fall armyworm, striga, mycotoxins; improves availability of nitrogen and phosphorus, and stores increased carbon in biomass and soils. Though much...
Abstract: Climate change raises a serious threat to global entomofauna—the foundation of many ecosystems—by threatening species preservation and the ecosystem services they provide. Already, changes in climate—warming—are causing (i) sharp phenological mismatches among host–parasitoid systems by reducing the window of host susceptibility, leading to early emergence of either the host or its associated parasitoid and affecting mismatched species’ fitness and abundance; (ii) shifti...
Abstract: The contribution of seasonality in species communities to elevational diversityof tropical insects remains poorly understood. We here assessed seasonal pat-terns and drivers of bee diversity in the Eastern Afromontane BiodiversityHotspot, Kenya, to understand the contribution of seasonality to elevationalbiodiversity patterns. Bee species and plant species visited by bees wererecorded on 50 study plots in regrowth vegetation across four major seasonsalong two elevation gradients fr...
INTRODUCTION Introduction to the topic of climate change in East Africa within the past decade is vital for understanding the environmental challenges faced by the region. Over the years, East Africa has experienced significant changes in weather patterns, including prolonged droughts, unpredictable rainfalls, and increased temperatures. These changes have had a profound impact on agriculture, water security, and the livelihoods of millions of people living in the region.
Abstract: The integration of indigenous knowledge and science through and ecosystem based adaptation provides a basis for the formulation of culturally acceptable and sustainable adaptation practices. This study aims to determine sustainable climate change adaptation strategies for the Taita Hills in Kenya and assess their potential for integration with ecosystem based adaptation. It uses a mixed methodology that involves literature review, participatory methods and household surveys. As a r...
Abstract: Climate Change and Variability affects water supply and food security, especially in developing countries where many small-scale farmers rely on rain-fed agriculture for food production and as a main source of livelihood. The extent of the effects of climate change and variability on these small-scale producers largely depends on their level of adaptation, adaptive capacity, exposure and vulnerability. This study evaluates the effectiveness of Conservation Agriculture (CA) as a pos...
