The solutions to desertification: case study- Khushab, the control and reclamation
project
Location and background
Northern Pakistan on the north bank of the Jhelum River.
400mm rain per year
Maximum temperatures exceed 40 degrees C May-July.
By late 1980's over irrigation caused water logging and soil salinity
problems.
Crop yields fell and land was abandoned leading to unemployment and
poverty for the areas' 8000 farming families.
Project
Financed by world bank- costs $69 million to reduce water logging and
Salinisation on 360km2 of land.
Land reclamation would increase agricultural production, create more jobs,
raise farm incomes
Water, logging and Salinisation were solved by installing field drainage by
using pipes, surface water drains and lining irrigation channels to prevent
seeping.
Demonstration farms were set up to educate farmers on sustainable water
management.
Impact
Completed between 1989 and 1994
Been very successful
Due to drainage: ground water levels fell lowering soil salinity, reducing
water logging. This halved during the first 2 years of the project.
This is possible due to improvements in land quality: increased production
of crops like rice, wheat, and sugar cane. Less waterborne diseases like
cholera and less damage to homes from land subsidence.
