چکیده
Smallholder farms in the semiarid and subhumid tropics are particularly vulnerable to increased climate variability. Indigenous agrisystems that have co-evolved with variability may developed resilience strategies. In Southwest Ethiopian Highlands, dominated by multipurpose perennial staple enset (Ensete ventricosum), characterised flexible harvest timing, high yield, long storage, putative drought tolerance, earning it name ‘the tree against hunger’. We tested three hypotheses using crop production area data. First, is greatest most drought-prone locations. Second, farmers respond events increasing area. And third, encourages shifts agrisystem composition more widely towards or storable crops. found regions a higher severe frequency associated significantly proportion of production. Similarly, Standardised Precipitation Evapotranspiration Index previous 3 years negatively correlated time series, suggesting prior drier conditions led increase land under Regarding other crops, storage crops roots tubers were also preferentially selected after long-term over annual indicating their capacity for longer-term resilience. Promoting such as perennials, which extensive established root systems, be strategy ensure food security during These results indicate potential farmer's strategies improve changing climate.
