Sir: It is unfortunate that the Indus delta — the sixth largest in the world — is on the verge of collapse due to a man-made disaster for the last many years. It was envisaged in the 1991 Water Accord that a mandatory limited amount of water would be released downstream Kotri till a survey was conducted to fix the exact quantity of water to be released. But even after the lapse of 23 years of the signing of the Accord, it is not being implemented in letter and spirit due to the intransigence of Punjab. Consequently, 2.6 million people living in the area between Kotri and the Arabian Sea are facing hunger and thirst. The absence of the supply of water downstream Kotri has resulted in the destruction of the Indus delta, inundation of 2.7 million acres of fertile land in Badin and Thatta by sea water and the elimination of fauna and flora of the area. These are the major problems the people of Sindh are facing nowadays. Perhaps the federal government is unable to save the Indus delta, because it does not fall in Punjab. It is unfortunate that some people in the ministry of water and power, IRSA and WAPDA want to turn Sindh completely into a desert by not implementing the Accord that includes releasing the mandatory limited water downstream Kotri.
