摘要

Climate variability and soil degradation threaten livestock and crop production in the Eastern Cape Province of South Africa. We used semi-structured questionnaires and interviews to gather local knowledge about the impact of soil quality indicators (SQI) and climate variability on farm productivity. The results showed no significant difference in the association between the knowledge of SQI and the farming experience or age of the farmer, except for soil organic matter (p = 0.047) and soil biology (p = 0.018). The prolonged drought, low rainfall, and poor soil quality were the major causes of the decline in production. Changes in grazing management and the addition of chemical fertilizers were mentioned to perpetuate soil erosion gullies, increase soil acidity and compaction, and lower soil moisture. Adopting crop and livestock practices such as rotation, manure, and compost application improved soil moisture, fertility, and general agricultural productivity amid the observed climate variability. The results provide helpful information for policymakers and scientists to create agricultural practices tailored to farmers’ understanding that will assist in mitigating the effects of climate variability and land degradation.
