Either we have droughts or we have floods. These unwelcome guests have been visiting in turn to play havoc with the peace and stability of our country. This might be due to global warming or might actually be the wrath of Almighty, lack of dams or good governance but whatever the cause, we need to do some serious strategic thinking and farsighted planning. On floods, since that is the blight we are stricken with at present, why cant we have flood management plans that include extensive construction of levees, bunds, weirs and reservoirs? We must do work on this to avert future catastrophes. For now, though, the top most priority should be the millions who have been swept on to our doorsteps in the run of rivers. -M. A. KHAN, Lahore, August 10.
