“…Similar changes are modeled for dryland regions of West Africa (Diedhiou et al 2018), southern Africa (New 2018), and India (Ramarao et al 2019), suggesting that the coming decades will become more challenging, especially when considered alongside current natural resource degradation and livelihood precarity (Stringer et al 2017, IPCC 2019. The potential negative implications of these processes re-emphasize the importance of understanding why populations are vulnerable and the options they have to respond to livelihood threats (Cervigni et al 2016a, Shukla et al 2017.…”

Dryland regions are highly dynamic environments in which multiple pressures intersect, threatening livelihood security. Mobility is an integral feature in these environments and represents a key risk management strategy for people to respond to frequent livelihood shocks and stresses. Global environmental change scholarship has tended to articulate spatial and temporal change inadequately, portraying populations in a way that belies their socially differentiated and inherently mobile livelihoods. We explored the role of mobility as an ongoing, "everyday" adaptive response to changing environmental, economic, and social conditions. We draw on 21 Life History (LH) interviews to explore the drivers and outcomes of people's mobility behavior in drylands of Ghana, Kenya, Namibia, and India. We present the adaptation option space (AOS) as a novel theoretical development to explore livelihood trajectories. Within our cases, we found that mobility was ubiquitous and facilitated changes to and exchanges within people's risk profiles in three main ways: novelty (risks gained or lost), modification (risks attenuated or accentuated), and no change. Temporal analysis showed three broad trajectories in people's lives set within broader structural constraints: upward, downward, and stable, depending on people's abilities to manage their AOS. The analysis confirmed that the AOS was a useful heuristic to understand how people exert agency to respond to an array of converging risks while negotiating broader drivers of change. Moreover, the data demonstrated how compounding shocks had negative impacts on people, highlighting the value of temporally-sensitive approaches.

Fruit tree improvement has taken great strides by roping in improved and efficient biotechnological tools to increase fruit yield and quality to meet local and export demands. For the past decade, the RNA-Seq tool has successfully been used in fruit tree improvement programs to identify genes, dissect complex traits, and understand different molecular pathways and differential expression of genes. However, despite their growing importance in food and nutrition security, medicinal uses, and climate change mitigation strategies, very little has been done to improve the pomological traits of African indigenous fruits, especially at the molecular level. African indigenous fruit trees exhibit unexplained variation in flowering, fruit load, fruit size, fruit ripening, fruit taste, fruit nutritional composition and shelf-life. The booming local commercial companies and export markets are demanding consistent quality indigenous fruits. This has necessitated the need for fast and effective tools that will hasten the understanding and improvement of fruiting qualities. The improvement of fruiting and fruit qualities will go a long way in accelerating the domestication and commercialization of African indigenous fruit trees. This review paper gives molecular biology insights on how RNA-Seq has been successfully used in fruit improvement of exotic fruits through gene identification, comparative transcriptome analysis under different conditions, and understanding molecular pathways that influence important pomological traits. The review article also unearths opportunities where RNA-Seq can improve our knowledge and improvement of undesirable traits common in African indigenous fruits
