Kosi basin to receive flood warnings

New Delhi: Kosi Basin is a disaster prone area with recurring floods which on annual basis destroys the livelihood of millions of people inhabiting that area. But the data to anticipate the life taking floods is usually not available.

However, an information system to tackle the threat has now been set up by a Kathmandu-based international organisation dedicated to environmentally-sound mountain development strategies.

“We have created a platform known as the Kosi Basin Information System (KBIS) that integrates data on climate change, land use, sedimentation, and water-based livelihoods to help individuals understand the changes happening in the basin,” Shahriar Wahid, Project Coordinator for the International Centre for Integrated Mountain Development (ICIMOD).

The 48-hour flood warning will be provided by the platform using the data collected from satellite technology and national weather agencies, he added.

A warning for a regional flood was issued for the first time the last monsoon by the Nepal’s Department of Hydrology and Meteorology.

India, China and Nepal together had been consistently working for past two years to be able to generate knowledge and information which will help communities in the basin prepare for disasters.

“The data and information are used by several institutions in India, Nepal and China for collaborative and development-oriented research on water, food, energy and environment in the basin,” Mr Wahid said.

He also added, the aim of KBIS focuses on facilitating data and information-sharing and promoting inter-disciplinary collaboration between different water stakeholders such as technical professional s,researchers and common people.

The Kosi River is commonly known as “Sorrow of Bihar” because of the annual floods affecting a large area of fertile agricultural lands. Due to the monsoon rains and glacial melting, water increases to as much as 18 times the average leading to a flood.

Floods have badly affected the livelihood of people in Bihar. They annually suffer loss of life, property, infrastructure and agriculture.

The 2008 flood was a disastrous one in the history of Bihar when the river changed the course and flooded the areas which remained unaffected since decades.

Nearly 3 million people were displaced from their homes while many were killed during the unfortunate disaster.

The 2013 Bihar flood was yet another miserable time when 3,768 villages in 20 districts were affected.

Kosi is one of the most sediment-laden rivers in the world, making it highly prone to flooding.(IANS)

Diesel Exhaust Converted Into Ink by Indian Innovators To Battle Air Pollution

Supervised by young engineers, workers at the start-up company Chakr Innovation in New Delhi cut and weld sheets of metal to make devices that will capture black plumes of smoke from diesel generators and convert it into ink.

Supervised by young engineers, workers at the start-up company Chakr Innovation in New Delhi cut and weld sheets of metal to make devices that will capture black plumes of smoke from diesel generators and convert it into ink.

In a cabin, young engineers pore over drawings and hunch over computers as they explore more applications of the technology that they hope will aid progress in cleaning up the Indian capital’s toxic air – among the world’s dirtiest.

While the millions of cars that ply Delhi’s streets are usually blamed for the city’s deadly air pollution, another big culprit is the massive diesel generators used by industries and buildings to light up homes and offices during outages when power from the grid switches off – a frequent occurrence in summer. Installed in backyards and basements, they stay away from the public eye.

“Although vehicular emissions are the show stoppers, they are the ones which get the media attention, the silent polluters are the diesel generators,” says Arpit Dhupar, one of the three engineers who co-founded the start up.

The idea that this polluting smoke needs attention struck Dhupar three years ago as he sipped a glass of sugarcane juice at a roadside vendor and saw a wall blackened with the fumes of a diesel generator he was using.

It jolted him into joining with two others who co-founded the start-up to find a solution. Dhupar had experienced first hand the deadly impact of this pollution as he developed respiratory problems growing up in Delhi.

A new business

As the city’s dirty air becomes a serious health hazard for many citizens, it has turned into both a calling and a business opportunity for entrepreneurs looking at ways to improve air quality.

According to estimates, vehicles contribute 22 percent of the deadly PM 2.5 emissions in Delhi, while the share of diesel generators is about 15 percent. These emissions settle deep into the lungs, causing a host of respiratory problems.

After over two years of research and development, Chakr has begun selling devices to tap the diesel exhaust. They have been installed in 50 places, include public sector and private companies.

The technology involves cooling the exhaust in a “heat exchanger” where the tiny soot particles come together. These are then funneled into another chamber that captures 70 to 90 percent of the particulate matter. The carbon is isolated and converted into ink.

Among their first clients was one of the city’s top law firms, Jyoti Sagar Associates, which is housed in a building in Delhi’s business hub Gurgaon.

Making a contribution to minimizing the carbon footprint is a subject that is close to Sagar’s heart – his 32-year-old daughter has long suffered from the harmful effects of Delhi’s toxic air.

“This appealed to us straightaway, the technology is very impactful but is beautifully simple,” says Sagar. Since it could be retrofitted, it did not disrupt the day-to-day activities at the buzzing office. “Let’s be responsible. Let’s at least not leave behind a larger footprint of carbon. And if we can afford to control it, why not, it’s good for all,” he says.

At Chakr Innovation, cups, diaries and paper bags printed with the ink made from the exhaust serve as constant reminders of the amount of carbon emissions that would have escaped into the atmosphere.

There has been a lot of focus on improving Delhi’s air by reducing vehicular pollution and making more stringent norms for manufacturers, but the same has not happened for diesel generators. Although there are efforts to penalize businesses that dirty the atmosphere, this often prompts them to find ways to get around the norms.
