According to the Soil Survey of Pakistan, the country's total waterlogged summer-rain acreage is:_________?
Show answer Hide answer
Answer: A. 4.11 mha
Explanation
Soil Survey of Pakistan data estimates the total waterlogged and saline-affected acreage within specific empirical thresholds. Agricultural surveys document approximately 4.11 million hectares impacted by these challenging hydrological conditions. Therefore, this specific statistical figure is the correct scientific estimate. Waterlogging and salinity pose severe threats to agricultural productivity in arid and semi-arid irrigation systems. High water tables bring salts to the surface, degrading arable land and reducing crop yields. Comprehensive soil surveys help governments prioritize drainage and reclamation projects.
Accurate acreage data allows agricultural planners to design effective subsurface drainage and soil reclamation programs. Mitigating waterlogging is crucial for sustaining long-term food security in regions heavily reliant on canal irrigation. Without such data, resource allocation for land remediation would fail. Options B and C provide incorrect acreage figures that do not match official soil survey data records. Option D is incorrect because the statistical statement provided in option A is factually supported by survey records. Valid official measurements exist for this agricultural metric.
