IntroductionThis study is aimed at analyzing farmers’ perception and adaptation to climate change in the Dabus watershed. It is based on analysis of data collected from 734 randomly selected farm household heads substantiated with Focus Group Discussions and field observations.MethodsThe study employed descriptive methods to assess farmers’ perception of climate change, local indicators of climate change and types of adaptation measures exercised to cope up with with the risk of the change in climate. The study also employed the Heckman sample selection model to analyze the two-step process of adaptation to climate change which initially requires farmers’ perception that climate is changing prior to responding to the changes through adaptation measures.ResultsBased on the model result educational attainment, the age of the head of the household, the number of crop failures in the past, changes in temperature and precipitation significantly influenced farmers’ perception of climate change in wet lowland parts of the study area. In dry lowland condition, farming experience, climate information, duration of food shortage, and the number of crop failures experienced determined farmers’ perception of climate change. Farmers’ adaptation decision in both the wet and dry lowland conditions is influenced by household size, the gender of household head, cultivated land size, education, farm experience, non-farm income, income from livestock, climate information, extension advice, farm-home distance and number of parcels. However, the direction of influence and significance level of most of the explanatory variables vary between the two parts of the study area.ConclusionsIn line with the results, any intervention that promotes the use of adaptation measures to climate change may account for location-specific factors that determine farmers' perception of climate change and adaptive responses thereof.

Smallholder farmers’ decisions to adopt adaptation options in response to climate change and variability are influenced by socioeconomic, institutional, and environmental factors, indicating that decision patterns can be very specific to a given locality. The prime objective of this research is to identify factors affecting smallholder farmers’ decisions to adopt adaptation options to climate change and variability in the Muger River sub-basin of the Blue Nile basin of Ethiopia. Both quantitative and qualitative data were collected using a semi-structured questionnaire, focused group discussions, and key informant interviews from 442 sampled households. Frequency, mean, Chi-square test, and one-way ANOVA were used for analysis. Furthermore, a multinomial logit model was employed to analyze the data. Results signified that small-scale irrigation, agronomic practices, livelihood diversification, and soil and water conservation measures are the dominant adaptation options that smallholder farmers used to limit the negative impact of climate change and variability in the study area. The results further revealed that adoption of small-scale irrigation as an adaptation to climate change and variability is significantly and positively influenced by access to credit, social capital, and the educational status of household heads. Greater distance to marketplace and size of farmland negatively affected the use of agronomic practices, whereas crop failure experience and access to early warning systems have a positive influence. The results also point out that adoption of soil and water conservation measures are positively affected by exposure to early warning systems, greater distance to the marketplace, and larger size of cultivated land. It is also noted that livelihood diversification is negatively influenced by socioeconomic factors such as education, the gender of the household head, and livestock ownership. Overall, the results suggested that improved policies aimed at increasing the adoption of adaptation options to offset the impact of climate change and variability should focus on: creating effective microfinance institutions and effective early warning systems, increasing farmer awareness, improving infrastructure, and encouraging farmers’ membership to many social groups. The results further suggested that agroecological and gender-based research should be promoted and increased for a more holistic understanding of farmer adaptation options.

Climate variability and change make agricultural sector a risky venture for smallholders’ farmers. This paper presents an assessment of smallholder farmers’ perceptions of climate variability and change, associated impacts on agricultural sector and the adaptive responses given in Fincha’a sub-basin of the Blue Nile River Basin of Ethiopia. We interviewed 380 head of households selected through systematic random sampling from eight Kebeles, two each from highland, midland, wetland, and lowland agro-ecosystems. Furthermore, focus group discussion and key informant interviews also performed to supplement and substantiate the quantitative data. Descriptive statistics used to summarize quantitative data and χ² tests used to measure significance. The result revealed that increased temperature, frequency and severity of extreme weather events (drought and flood), and overall change in seasonality of rainfall over the last 20 years is a widely held perception. The associated impacts on agriculture include decline in length of growing period, the decreased and variability of water availability, increased crop damage by insects, pests, disease and weeds. In response, farmers practiced different adaptation measures like modification in crop and livestock production practices, and investment in land and water management activities at household and community level. The study also revealed the presence of multiple barriers that hindered the adoption of adaptation measures. To meet the impending challenges, situate by climate variability and change the adaptation measures implemented until now is not adequate. There is also extrication between farmers’ perceptions of climate variability and change, and actual adaptation level. Despite significant number of farmers’ perceived changes in temperature (about 93%) and rainfall (about 88%), the number of farmers adopted certain adaptation measures are below average. These necessitate the need for planned interventions to identify and support effective adaptation measures.

BackgroundEthiopia is frequently cited as a country that is highly vulnerable to climate variability and change. The country’s high vulnerability arises mostly from climate-sensitive agricultural sector that suffers a lot from risks associated with rainfall variability. The vulnerability factors (exposure, sensitivity, and adaptive capacity) of the agricultural livelihoods to climate variability and change differ across agro-ecological systems (AESs). Therefore, the aim of this study was to analyze AES-specific vulnerability of smallholder farmers to climate variability and change in the Fincha’a sub-basin. We surveyed 380 respondents from 4 AESs (highland, midland, wetland, and lowland) randomly selected. Furthermore, focus group discussion and key informant interviews were also performed to supplement and substantiate the quantitative data. Livelihood vulnerability index was employed to analyze the levels of smallholders’ agriculture vulnerability to climate variability and change. Data on socioeconomic and biophysical attribute were collected and combined into the indices and vulnerability score was calculated for each agro-ecological system.ResultsConsiderable variation was observed across the agro-ecological systems in profile, indicator, and the three livelihood vulnerability indices-Intergovernmental Panel on Climate Change dimensions (exposure, sensitivity, and adaptive capacity) of vulnerability. The lowland AES exhibited higher exposure, low adaptive capacity, and high vulnerability, while the midland AES demonstrated lower exposure, higher adaptive capacity, and lower vulnerability. The wetland and highland AESs scored intermediate results.ConclusionOur results suggest that resilience-building adaptation strategies are vital to reduce the vulnerability of smallholder farmers. The measures taken should consider site-specific agro-ecological system requirements to reduce the vulnerability of smallholder mixed crop-livestock agriculture system. Since the approach based on the long-term realization of the community, any strategy designed based on such assessments is applicable to local condition.

This study analyzes land use/land cover dynamics in response to socioeconomic, political and climatic forces in the Didessa sub-basin of Blue Nile, Ethiopia for 1974–2014 using remote sensing, field observation and information from local people. A rapid reduction of wetland (97.5%), grass land (76%), forest land (50.6%) and shrub land (38.2%) took place in four decades (1974–2014). On the other hand, settlement increased extraordinarily (17,960.8%), while the size of cultivated land increased more than a fold (44.2%). Commercial farm land increased more than fivefold (414.4%). According to key informants, major events that largely explain the changes include: (1) drought and social unrest (e.g. Conflict and war); (2) demographic factors (resettlement and migration); (3) land tenure reform and political changes; (4) economic factors and decline in agricultural productivity. If the present land use/land cover changes continue coupled with climate change, people’s livelihoods will be highly affected and agricultural production system will be under increasing threat. This study suggests the restructuring of land use planning supposed to be based on land suitability and sustainable protection of fragile environments. These findings contribute to the understanding of patterns of the dynamics of historical land use change to predict the future dynamics at landscape scale to contribute for effective management strategies and policies for the rational use of land and land related resources.

Ethiopian climate-sensitive economy is particularly vulnerable to the effects of climate-related extreme events. Thus, examining extreme daily precipitation and temperature in the context of climate change is a critical factor in advocating climate change adaptation at the local scales. Spatial changes of climate indices for extreme precipitation and temperatures were conducted for the period 1986–2016 in three different agroecologies of the Gurage zone, Southern Ethiopia. The study used the Mann–Kendall (MK) test and Sen’s slope estimator to estimate the trend and magnitude of changes in precipitation and temperature. The analysis from the observation indicates that there had been a consistent warming trend and inconsistent changes in precipitation extremes in the study agroecologies. A statistically significant increase in the numbers of warm days and nights and a statistically significant reduction in the numbers of cold days and nights were observed in most of the agroecologies. The duration of extreme trend showed inconsistency; however, a drier condition is observed in lowland agroecology. Therefore, based on the findings of this study, appropriate climate adaptation efforts are needed at the local scale.

Background Climate change adaptation is an incomparable prior measure to tackle unpreventable climate calamities to enhance smallholder farming and food security. This empirical study assesses smallholder farmers' adaptation options to climate change or variability for achieving food security. Methods Data were gathered from a survey of 328 respondents, selected randomly and proportionally from three different agro-ecological zones. Additional qualitative insights were collected through focus group discussions and interviews with key informants to reinforce the findings. The multinomial endogenous switching regression, independent t-test and the instrumental variable (2sls) regression were used as method of analysis Results The result indicated that ACAC impacted food security positively and significantly in the study area at a percent rate of 12.4, 16.3,18 and 27.7 when households adopting one, two, three, and four ACAC, respectively, in the HFBM case, and the same meaning was obtained from other food security measuring tools. However, the rate and manner of change differ at different agroecologies, signifying careful discernment when applying ACAC at different spacial areas, especially in agroecology. The change in agroecology declares that midlands have a negative likelihood propensity for climate adaptation compared to highlands, while lowlands have positive and insignificant implications. The mean comparison from the independent t-test showed statistically significant adopters and non-adopters food security measures, which also informed the positive contribution of CACA on households' food security. Interestingly, factors such as distance to water sources, land size, ox ownership, crop income, and access to credit influenced food security in diverse ways depending on regional and contextual specifics. Conclusions Thus, ACAC impacts food security differently at different rates in different agroecologies in the area. Integrated and tailored technical, institutional, and policy interventions are needed to tackle the calamities of climate change leap to smallholder farming and food security

The study aims to assess trends in extremes of surface temperature and precipitation through the application of the World Meteorological Organization’s (WMO) Expert Team on Climate Change Detection and Indices (ETCCDI) on datasets representing three agroecological zones in Southern Ethiopia. The indices are applied to daily temperature and precipitation data. Nonparametric Sen’s slope estimator and Mann–Kendall’s trend tests are used to detect the magnitude and statistical significance of changes in extreme climate, respectively. All agroecological zones (AEZs) have experienced both positive and negative trends of change in temperature extremes. Over three decades, warmest days, warmest nights, and coldest nights have shown significantly increasing trends except in the midland AEZ where warmest days decreased by 0.017°C/year (p<0.05). Temperature extreme’s magnitude of change is higher in the highland AEZ and lower in the midland AEZ. The trend in the daily temperature range shows statistically significant decrease across AEZs (p<0.05). A decreasing trend in the cold spell duration indicator was observed in all AEZs, and the magnitude of change is 0.667 days/year in lowland (p<0.001), 2.259 days/year in midland, and 1 day/year in highland (p<0.05). On the contrary, the number of very wet days revealed a positive trend both in the midland and highland AEZs (p<0.05). Overall, it is observed that warm extremes are increasing while cold extremes are decreasing, suggesting considerable changes in the AEZs.

IntroductionThe purpose of this study is to evaluate the associated impact of adoption of adaptation options to climate change and variability on household food security in the Muger sub-basin of the upper Blue-Nile of Ethiopia using a comprehensive data of 442 sampled households from four representative districts’ in the sub-basin. The study used a propensity score matching approach to evaluate the impact of adaptation options on household food security.ResultsResults show that the decision to adopt adaptation options is found to be positively influenced by male household heads, family size, access to extension service, the size of landholding, and frequency of drought and floods over the past many years. The results further reveal that farmers adopting any of the adaptation options had higher food calorie intake per day per adult equivalent than those who did not.ConclusionsA policy that promotes the adoption of soil and water conservation measures, small-scale irrigation, agronomic practices, and livelihood diversification strategies should be central to food security strategy in the study area.

BACKGROUND : Africa faces diverse and complex population/human health challenges due to climate change. Understanding the health impacts of climate change in Africa in all its complexity is essential for implementing effective strategies and policies to mitigate risks and protect vulnerable populations. This study aimed to outline the major climate change-related health impacts in Africa in the context of economic resilience and to seek solutions and provide strategies to prevent or reduce adverse effects of climate change on human health and well-being in Africa. METHODS : For this narrative review, a literature search was conducted in the Web of Science, Scopus, CAB Abstracts, MEDLINE and EMBASE electronic databases. We also searched the reference lists of retrieved articles for additional records as well as reports. We followed a conceptual framework to ensure all aspects of climate change and health impacts in Africa were identified. RESULTS : The average temperatures in all six eco-regions of Africa have risen since the early twentieth century, and heat exposure, extreme events, and sea level rise are projected to disproportionately affect Africa, resulting in a larger burden of health impacts than other continents. Given that climate change already poses substantial challenges to African health and well-being, this will necessitate significant effort, financial investment, and dedication to climate change mitigation and adaptation. This review offers African leaders and decision-makers data-driven and action-oriented strategies that will ensure a more resilient healthcare system and safe, healthy populations—in ways that contribute to economic resiliency. CONCLUSIONS : The urgency of climate-health action integrated with sustainable development in Africa cannot be overstated, given the multiple economic gains from reducing current impacts and projected risks of climate change on the continent’s population health and well-being. Climate action must be integrated into Africa’s development plan to meet the Sustainable Development Goals, protect vulnerable populations from the detrimental effects of climate change, and promote economic development.
