Sir: It is very unfortunate that the Indus delta, the sixth largest in the world, is on the verge of death due to manufactured disasters for the last many years. It was envisaged in the 1991 Water Accord that at least 10 MAF water was to be released downstream Kotri till a survey was conducted to fix the exact quantity of water to be released. Unfortunately, even after 22 years of signing the Accord, it has not been implemented in letter and spirit due to the intransigence of the various Punjab governments. Consequently, 2.6 million human beings living in areas between Kotri and the Arabian Sea face hunger and thirst and live miserably. It is very unfortunate that the non-release of badly required water downstream of Kotri has resulted in the destruction of the Indus delta. Intrusion of seawater inundating 2.7 million acres of fertile land in Badin and Thatta districts of Sindh, besides bringing environmental disaster in the area, is a major problem people face nowadays. Obviously, the federal government is unable to save the Indus delta. It is very sad that some people of Lahore, in connivance with the controversial WAPDA, bureaucrats of the Ministry of Water and Power and the Punjab government, want to turn Sindh into a desert by not implementing the Accord.
