“…Among these methods, the indicator-based method is widely used to assess vulnerability to climate change and natural hazard-induced disasters (Pandey and Jha 2012;Salik et al 2015;Mohmmed et al 2018). In the past decade, the livelihood vulnerability index (LVI) has been a useful and popular tool in assessing farmers' vulnerability to climate change and disasters around the world (Addisu Legese et al 2016;Panthi et al 2016;Adu et al 2018;Oo et al 2018;Williams et al 2018). Computed and improved by Hahn et al (2009) based on the Intergovernmental Panel on Climate Change (IPCC) definition of vulnerability, the LVI approach consists of various variables apprehending the level of smallholder farmers' exposure, sensitivity, and adaptive capacity to natural hazard-induced disasters (for example, droughts and floods) and climate change.…”

In recent years, droughts have strongly affected the Central Highlands of Vietnam and have resulted in crop damage, yield decline, and serious water shortage. This study investigated the livelihood vulnerability of five communities of farmers who are exposed to droughts in one of the more vulnerable regions of Vietnam-Dak Nong Province. A survey of 250 households was conducted in the five communities to collect data on the region's sociodemographic profile, livelihood systems, social networks, health status, food and water security, drought conditions, and climate variability. Data were aggregated using a livelihood vulnerability index and the IPCC vulnerability index. The survey results indicate that Quang Phu community is the most vulnerable of the study's communities, followed by Nam N'dir, Dak Nang, Duc Xuyen, and Dak D'ro in descending order of vulnerability. Water availability and livelihood strategies are the most important variables in determining the vulnerability of the five surveyed communities. In order to reduce vulnerability to droughts, water management practices and livelihood diversification in farming and nonfarming activities are recommended for the study area.

“…The education level of the respondents was low where 30.9% of them were illiterate and the remaining 70.1% were literate. Household heads with higher levels of education believed to have a better level of planning, access and effectiveness of early warning information from different sources, better reactions and rehabilitation skills during and after natural shocks, alter agricultural operation and adopt extension strategies (Legese et al, 2016;Muttarak and Lutz 2014). Education tends to improve the ability of smallholder farmers to better comprehend issues affecting them and therefore look for possible solutions (Etwire et al, 2013).…”

Background: Climate change and variability has been significantly affecting the Ethiopian agricultural production and thereby smallholder farmers livelihoods. The level of vulnerability varied across agro-ecological zones (AEZs). Identification of difference in the level of vulnerability of a system is important in selecting appropriate and effective adaption options to climate change. Therefore, the aim of this study was to analyze the level of vulnerability of agricultural communities to climate change and variability at micro-scale level in five agro-ecological zones (AEZs) of south Wollo, north east highlands of Ethiopia. Data was collected from a representative of 502 sample households from five AEZs through multi stage random sampling methods. Focus group discussion and key informant interviews were also carried out to supplement and substantiate the quantitative data. The indicator based approach was used to empirically calculate vulnerability. Principal Component Analysis (PCA) was applied to give weight for indicators and generate index of vulnerability contributing factors. Results: The results showed that each of the vulnerability contributing factors (exposure, sensitivity and adaptive capacity) varied across the AEZs. M3, SM2 and SM3 are the most exposed AEZs but having a relatively better adaptive capacity whereas M1, M2 and M3 are the most sensitive AEZs with relatively low adaptive capacity to climate variability and change. Overall, SM2 is the most vulnerable AEZ which exhibited high sensitivity and low adaptive capacity followed by M1. Conclusions: The study explored sources and levels of vulnerability to each agro-ecology. Since the study is conducted at micro-scale level, it helps decision makers and development partners to have context-specific understanding of the impact of climate change and variability and design appropriate adaptation measures to address the specific situations.

“…Cognizant of this, the study was conducted in Rib watershed of Northwest Ethiopia and is framed to address three issues. Firstly, various adaptation practices are being undertaken in the country aimed to cope with the impact of climate change, reduce land degradation and rehabilitate the ecology [18][19][20]. However, the contribution of these practices is marginal [21] and the aforementioned problems have persisted.…”

Smallholder farmers require viable adaptation strategies for climate change. Adaptation project might be mal-practiced unless it considers the local diversity. This paper argued that the challenge of agriculture in developing countries in general and Ethiopia, in particular, is much diversified and thus interventions require a systematic shift to specific agro-ecosystems. In light of this, we used agro-ecosystem analysis to design locally appropriate adaptation strategies specific to Rib watershed in Ethiopia. The agro-ecosystem uses three inputs of agro-climatic zoning, soil type and terrain analysis, and farming systems. We used primary data collected from 383 randomly selected farm-households. The survey data was supplemented by key-informant interviews, focus group discussions and secondary data. We characterized and mapped the study area in two distinct groups of agro-ecosystems: Fogera plain and Libo-Farta highlands. The finding portrayed that across these agro-ecosystems, there was considerable difference in the: potentials, constraints, crop type, income distribution, and soil type. We found blanket application of the same strategies irrespective of these heterogeneities. The income distribution shows that the poorest 20 percent of the population share about 5 percent of the income. Relatively the plain has less income inequality with 38.3 as compared to the highlands Gini coefficient of 42.8. Looking only at the average distribution of income does not reveal the inequality. It is important to disaggregate into the specific agroecosystems. The study identified that drainage projects, fruit trees, and fishing are among the prioritized adaptation strategies for the plain while conservation structures, irrigation, agroforestry are tailored to the highland areas. It is important to consider diversities before intervention.
