The last two decades have seen a rise of interest in the adoption and diffusion of agricultural technologies aimed at improving the sustainability of agricultural lands among smallholder farmers in developing *** papers set out to understand factors that influence the adoption of technologies that enhance soil carbon sequestration among smallholder farmers,using secondary data recorded in the World Overview of Conservation Approaches and Technologies(WOCAT)database from 45 to 50 smallholders'farmers in selected places in Kenya and Ethiopia respectively.A Probit model was used to analyse whether socio-economic,institutional,off-farm income,technical know-how,farmers'percep-tions,and land use characteristics influences the adoption of technologies that enhance soil carbon *** results show that smallholder farmers that positively perceived net benefits of the soil carbon enhancing technologies were more likely to adopt such technologies that enhance soil carbon sequestration in both *** to off-farm income and land ownership with title deeds were also found to be positively associated with ***-farm income positively influences adoption among farmer with a moderate income(100-500US$per year)but not the rich(>500US$)*** to high level of skills and technical know-how required for implementing and maintaining a technology on the farm had a negative influence on *** shows that interventions,aimed at addressing specific factors such as inadequate skills and knowledge,change in perception among farmers,and off-farm income are likely to have the greatest impact in decisions relating to the adoption of the soil carbon enhancing practices among farmers in East Africa.

Climate change adaptation strategies provide a cushion for smallholder farmers,especially in subSaharan Africa against the risks posed by climate hazards such as droughts and ***,the decision-making process in climate adaptation is *** better understand the dynamics of the process,we strive to answer this question:what are the potential trade-offs and synergies related to decision-making and implementation of climate adaptation strategies among smallholder farmers in sub-Saharan Africa region?A systematic literature review methodology was used through the Preferred Reporting Items for Systematic Review and Meta-Analysis(PRISMA)statement with the four-stage inclusion/exclusion criteria to identify the literature from selected databases(Scopus and google Scholar).The climate adaptation strategies are organized into five broad categories(crop management,risk management,soil/land management,water management,and livestock management strategies).Evidence suggests that potential trade-offs may arise concerning added costs,additional labor requirements,and competition among objectives or available *** synergies,on the other hand,arise from implementing two or more adaptation strategies concurrently in respect of increased productivity,resilience,yield stability,sustainability,and environmental ***-offs and synergies may also differ among the various adaptation strategies with minimum/zero tillage,comparatively,presenting more *** development and promotion of low-cost adaptation strategies and complementary climate adaptation options that minimize the trade-offs and maximize the synergies are *** and knowledge on proper implementation of climate change adaptation strategies are encouraged,especially at the local farm level.
