- Long-term conservation agriculture effects on soil erosion and runoff in Eastern Cape, South Africa (2026) · Journal of Soils and Sediments · doi
The gap is in understanding the effects of conservation agriculture on soil erosion and runoff in the Eastern Cape, South Africa. There is a need to investigate the effects of tillage, crop rotation, and crop residue management practices on soil loss and runoff.

Soil degradation and declining soil fertility are significant concerns in intensive agricultural systems. The creation of dike systems has limited the deposition of alluvial soil, exacerbating soil degradation. Climate change and soil management practices may also influence soil degradation.

The estimates of yield gaps-and consequently the role of land degradation-are conservative lower bounds. The study acknowledges that if land degradation is sufficiently widespread, even the 95th percentile may reflect somewhat degraded conditions.

Land degradation is a gradual, cumulative process that is not well captured by short-term temporal fluctuations. The study must control for various confounding factors that affect crop yields. The analysis requires high-resolution data on land degradation and crop yield gaps.

Further research is needed to explore the mechanisms by which land degradation affects crop yields. The study suggests that addressing land degradation is crucial for maintaining agricultural productivity, and future research should focus on developing strategies to mitigate land degradation.
