Coping and adaptation role of Rhamnus prinoides-based indigenous agroforestry practice to climate variability among smallholder farmers in the drylands of Northern Ethiopia
摘要
Climate variability impacts are observed and expected to increase in the future, particularly in drylands. Continuous exposure to climate variability problems has prompted farmers to develop effective local coping and adaptation strategies. This study investigates the contribution of Rhamnus prinoides-based indigenous agroforestry practices by smallholders in coping with and adapting to climate variability in the drylands of Tigray, Ethiopia. Data was collected through questionnaires from 191 randomly selected households. Descriptive statistics were used to assess farmers’ perceptions of climate variability and evaluate the coping and adaptation role of R. prinoides agroforestry. Poisson and binomial models were used to identify determinants of the number and choice of coping and adaptation strategies of farmers. Farmers’ perceptions coincided with the actual climate data regarding increased variability of rainfall. R. prinoides-based agroforestry was widely practiced (70.2%) and played a significant role in coping with and adapting to climate variability impacts through bridging seasonal income shortfalls, maximizing production, and stabilizing and sustaining the productivity of smallholder farmers. It was complementary with other coping and adaptation strategies and served as the main source of cash income that could be invested in the purchase of improved varieties. The number and choice of coping and adaptation strategies used by smallholder farmers were significantly influenced by landholding size, farm fertility, farm fragmentation, tenure security, family size, climate awareness, age and education of household head. Thus, farming systems that incorporate trees/shrubs such as R. prinoides agroforestry could enhance the coping and adaptation capacity of smallholder farmers in the drylands.
