STUDY OF SOIL EROSION, SEDIMENTATION AND ASSOCIATED PESTICIDE CONTAMINATION
Manzoor Ahmad Choudhry
Head Radioisotope Hydrology Group
Radiation and Isotope Application Division
Pakistan Institute of Nuclear Science & Technology
P. O. Nilore, Islamabad, Pakistan
Phone: 92 51 9290261
Fax: 92 51-9290275
Total Population: 130 M (agribusiness 60%)
Total area: 79.61 M.ha.
Cultivated: 23.0 M.ha. (25% rain-fed)
Climate: arid and semiarid
Annual Rainfall: 100 to 2000 mm
(Extreme floods in monsoon)
Temperature: Below freezing to 52oC
soil erosion is the most severe
problem in rain-fed areas
Aggravated productivity decline due to soil erosion
Soil loss (3.0 - 4.5 t/ha/yr from cultivared fields)
Siltation of conveyance systems and reservoirs
Environmental pollution(water pollution sue to agrochemicals
