Summary

This paper reviews the impacts of soil salinity and sodicity, together with the use of saline irrigation water, on crop productivity in dryland farming systems, likely with a focus on sub-Saharan African or Ethiopian contexts given the authorship. It synthesises existing knowledge on the physiological and agronomic consequences of salt stress for crops, and evaluates coping mechanisms — such as salt-tolerant varieties, soil amendments, and improved irrigation practices — available to smallholder and dryland farmers. The review is likely intended to inform land management decisions and agricultural policy in salt-affected regions where food security is under pressure.

UK applicability

The findings are most directly applicable to semi-arid and arid regions with saline soils, particularly in East Africa; relevance to UK conditions is limited, though lessons on managing irrigated systems and salt-affected soils may have some applicability in coastal or reclaimed fenland areas of England.

Key measures

Crop yield reduction under salinity stress; soil electrical conductivity (EC, dS/m); sodium adsorption ratio (SAR); exchangeable sodium percentage (ESP); coping or management strategy effectiveness

Outcomes reported

The study examined how soil salinity, sodicity, and saline irrigation water affect crop yields and plant physiology in dryland farming contexts, and reviewed or assessed practical coping mechanisms available to affected farmers.
