Prospects of alternative copping systems for saltaffected soils in Ethiopia

Soil salinization is one of the major constraints in achieving food security and reducing environmental degradation in Ethiopia.‎ Restoration of salt-affected lands into productive lands and protection of newly developed areas from the spread of salinity is therefore of paramount importance.‎ In highly salinity areas where technical solutions to soil rehabilitation are expensive and time consuming and growth of normal field crops is restricted, use of bio-remediation methods including planting halophytic forages could bring saline soils back into production.‎ This paper identifies different causes of salinity and characterizes soils based on severity of salinity levels.‎ The paper suggests that biosaline agriculture is an economical and effective approach to use unproductive saline lands for growing different food and fodder crops in Ethiopia.‎ This approach, if prudently adapted, can help in improving livelihood of rural and pastoral communities of the salt-affected areas by enhancing feed and fodder production.‎ The paper has recommended many unexplored and unexploited genetic variation that can be harnessed to improve the salt tolerance of field crop species.‎ Productivity of marginal lands can be maximized for field crops and fodder species and varieties that can tolerate soil salinization and poor irrigation water quality.‎
