Managing salinity in Central Asia: licorice a tool in rehabilitating abandoned irrigated lands Dr Akmal Karimov, Dr Habibjon Kushiev IWMI Central Asia. Uniting Agriculture and Nature for Poverty Reduction
2
The Issue 34 million hectares (11%) of globally equipped irrigated area is abandoned or underperforming due to salinity Represents an annual loss of $11 billion annual In Central Asia 50% of irrigated area affected by degrees of salinization Elevated water tables that mobilize salt in the profile Drainage systems do not work effectively – lack of maintenance and investments
3
The Research Approach Need an effective and inexpensive approach to address the problem Dewatering the profile with deep rooted species endemic to Central Asia – Licorice (Glycyrrhiza glabra) Tolerates salinity; market for root extracts: industrial uses; pharmaceuticals; food and beverages (Coca Cola) Forage can be fed to livestock – protein content of 12% Licorice is a perennial shrub; tolerates harsh winters -20C
4
The Research Results Forage/root production – income in the remediation process Dewatered profile Revert back to a wheat cotton rotation after 3-4 years
5
Outcomes of the Research Licorice (Glycyrrhiza glabra) for amelioration of salt- affected soils and income generation, Uzbekistan Salt-affected soils in Syr Darya, Uzbekistan, 2005 Growing licorice on abandoned salt-affected: Increases the price for cultivated licorice Area of cultivated licorice increased from 4ha to 500ha Factory establish to process 9 000 ton to extract roots Assisting World Bank and the Uzbek government in an investment associated with rehabilitating 10,000 ha of salinized land PIM undertaking assessment of markets and value chains for licorice
