It’s sad to read about the deaths of several Indus River dolphins in Pakistan recently.

According to Yahoo News:

“Wildlife authorities say they have found the carcasses of six endangered river dolphins in Pakistan over the last month.

Sindh Wildlife Department deputy head Ghulam Mohammad accused on Monday local fisherman, saying their poison and nets were to blame for the deaths of the Indus River Dolphin.

The blind mammal is found only in the Indus River. A 2006 survey put the numbers left in the river at 1,300.

Increasingly low water levels and the spilling of pesticides into the river have reduced the dolphins’ habitat.”

The Indus River dolphin is now considered a separate species from the Gangetic Dolphin, but it is facing similar challenges to the Gangetic dolphin in terms of pollution of river habitats.  According to Wikipedia:

” The Ganges River Dolphin (Platanista gangetica gangetica) and Indus River Dolphin (Platanista minor minor) are two sub-species of freshwater or river dolphins found in Bangladesh, India, Nepal and Pakistan. The Ganges River Dolphin is primarily found in the Ganges and Brahmaputra Rivers and their tributaries in India, Bangladesh and Nepal, while the Indus River Dolphin is found in the Indus river in Pakistan and its Beas and Sutlej tributaries. From the 1970s until 1998, they were regarded as separate species; however, in 1998, their classification was changed from two separate species to subspecies of a single species .”

Here are a few videos showing the threats to the Indus River dolphins and the efforts to protect them. WWF estimates there are only 1000 or so left and have been declared as an endangered species. The threats include reducing volumes of water which are siphoned away for agriculture, and toxic pollutants which bio-accumulate. The health of the dolphins is a reflection of the health of the rivers.

Kanpur in Uttar Pradesh, India  is a major centre for leather tanneries, much of it for export to consumers in US, Europe and the rest of the world.  These tanneries let out toxic effluents such as sulphides and chromium salts  into River Ganga, which is home to the endangered Gangetic Dolphins as well as several other species which are threatened by such pollution.

According to the recent article in The Hindu.

The Uttar Pradesh Pollution Control Board has ordered closure of five more tanneries in Kanpur which were discharging their sewage in river Ganga despite several notices against it, officials said on Thursday.

With this, as many as 69 tanneries in the city have been asked to shut their operations for polluting the river.

According to the Board, despite repeated notices, these tanneries had failed to install primary treatment plants in their units and were discharging polluted water in the river.

Pollution Control Board’s regional officer Radhey Shyam said the orders to close the tanneries have been received and the procedure to shut them down will start on Friday.

The permission to shut down nine more polluting tanneries has been sought from the UPPCB, he said.

Owners of many tanneries claimed that implementation of this decision would affect nearly 50 thousand labourers and leather business worth around Rs. 2,500 crore.

Here are two videos that show the impact of the leather tanning centres.  The first one shows how a “combined effluent treatment plant diverts the waste water from the tanneries, and treats it alongwith domestic sewage water. But efforts are still required to motivate individual tannery owners to set up chrome recovery plants for the treatment process to be truly effective.”

The second is a National Geographic Video which shows activist, Prakash Jaiswal’s efforts through the organisation Eco Friends, to halt the poisoning from the tanneries which amounts to 20 million litres per day of sewage and toxic effluents containing, lead, arsenic and mercury, which make many parts of River Ganga around Kanpur a dead zone.

“Workers at one of Kanpur’s four hundred tanneries, the city’s primary industry, load hides into well-used tumblers. Treating leather in this manner is a multi-step process requiring chemicals such as chronium and copious amounts of water. After the water is used, and thus highly polluted to human and animal use, it is more often than not piped back to the Ganges without any treatment.”
