Minimum Environmental Flows in Rivers

Dear eflownet members,

We have a request for information on Minimum Environmental Flows in Rivers in Pakistan. If you have any information please email Mr. Mughal directly at mug444@yahoo.com
-------------------------------------------------------------------------------------------------
River Indus, here is Pakistan, at its downstream end, is adversely impacting the overall environment and ecology of the area. Due to heavy abstractions, on the upstream reaches, there is, almost, no flow in the river, at its downstream end. As a result, water supply sources have been disrupted, sea has made inward intrusion, economy of the area has been badly affected, due to no agriculture, mangroves have been wiped out; the list goes on and on.
I would like to know, what minimum environmental flows should a river have (in this case, in Indus River), to prevent disruption to environment, ecology and economy. You may like to send me some publications, in addition to your valued inputs.
Kind regards,
F H Mughal (Mr.)

[On behalf of Mr Bonani Madikizela, Research Manager, Water Research Commission]

Good day Mr F H Mughal and Compliments to you too !
Great question, I wish I had a single answer to your enquiry ! I copy my colleagues in the Department of Water Affairs, South Africa who are implementing such methods in our rivers and some may have worked in the rivers outside South Africa. I do not have Prof Jay O’Keeffe’s e-mail address. He works for UNEP . We had a chat while he was in South Africa for a conference on Limnology, where he mentioned implementation of the ecological reserve (or environmental flow requirements) in various countries, including Pakistan.

From Water Research Commission point of view, I would request you to try and visit out information hub, via the website: www.wrc.org.za. There you will find a number of documents related to perennial and non-perennial environmental flow requirements procedures/methods. These are not necessarily simply procedures as per your question, managing water resources and deciding on water allocation is a very complex exercise, yet very important for sustainable development as you would like to see in your country. If you need any explanation on the methods and procedures, let us know, we would be very pleased to offer any assistance possible to help you guys manage your rivers using our scientifically proven methods.
