Understanding how to build livelihood resilience to an uncertain future is critical as livelihood systems must adapt to local and regional climatic change. Agroforestry, the integration of trees into an agricultural landscape, is one potential solution. However, while many intuitively link agroforestry with livelihood resilience, there is little factual evidence. This paper utilizes data from semi-arid Isiolo County, Kenya to explore if and how agroforestry is building livelihood resilience for smallholder farmers. This study included 20 qualitative case study households, 339 quantitative household surveys, and key informant interviews. In order to measure livelihood resilience, we drew from the five livelihood capital assets of the sustainable livelihoods approach: financial, human, social, physical, and natural capital. The major benefits of agroforestry were shade and fruit; the main tree species planted included mango, papaya, banana, guava, and neem. The average of all five livelihood capital scores was 10% higher for households practising agroforestry, indicating that those households may have more resilient livelihoods. Livelihood capitals were improved by both on-farm diversification and off-farm livelihood diversification. Agroforestry improved the overall quality of life for respondents. This paper provides four major findings that may be applied to build livelihood resilience through agroforestry.

Mobile phone use is increasing in Sub-Saharan Africa, spurring a growing focus on mobile phones as tools to increase agricultural yields and incomes on smallholder farms. However, the research to date on this topic is mixed, with studies finding both positive and neutral associations between phones and yields. In this paper we examine perceptions about the impacts of mobile phones on agricultural productivity, and the relationships between mobile phone use and agricultural yield. We do so by fitting multilevel statistical models to data from farmer-phone owners (n = 179) in 4 rural communities in Tanzania, controlling for site and demographic factors. Results show a positive association between mobile phone use for agricultural activities and reported maize yields. Further, many farmers report that mobile phone use increases agricultural profits (67% of respondents) and decreases the costs (50%) and time investments (47%) of farming. Our findings suggest that there are opportunities to target policy interventions at increasing phone use for agricultural activities in ways that facilitate access to timely, actionable information to support farmer decision making.

Ethiopia has experienced more than 10 major drought episodes since the 1970s. Evidence has shown that climate change exacerbates the situation and presents a daunting challenge to predominantly rain-fed agricultural livelihoods. The aim of this study was to analyze the extent and sources of smallholder famers’ livelihood vulnerability to climate change/variability in the Upper Blue Nile basin. We conducted a household survey (n = 391) across three distinct agroecological communities and a formative composite index of livelihood vulnerability (LVI) was constructed. The Mann–Kendall test and the standard precipitation index (SPI) were employed to analyze trends of rainfall, temperature, and drought prevalence for the period from 1982 to 2016. The communities across watersheds showed a relative difference in the overall livelihood vulnerability index. Aba Gerima (midland) was found to be more vulnerable, with a score of 0.37, while Guder (highland) had a relatively lower LVI with a 0.34 index score. Given similar exposure to climate variability and drought episodes, communities’ livelihood vulnerability was mainly attributed to their low adaptive capacity and higher sensitivity indicators. Adaptive capacity was largely constrained by a lack of participation in community-based organizations and a lack of income diversification. This study will have practical implications for policy development in heterogeneous agroecological regions for sustainable livelihood development and climate change adaptation programs.
