East India Sand Mining 2018: Will NGT order help restore Subarnarekha River?

Bihar Unsustainable sand mining causing floods in West Champaran The sand mining in the rivers of West Champaran was causing unmitigated floods in the region, year after year but the govt failed to respond.

– West Champaran district also sees many floods in the non-monsoon months, many of which go unreported, and often, ignored by flood-relief schemes. The natural explanation for the flash floods is that the region is at the foothills and rivers from the hills of bordering Nepal flow through it. But the floods are not entirely a result of natural phenomena. Over the years, excessive sand mining in the river beds has led to ecological imbalances, making rivers and streams flood and even change their course, wreaking havoc in the villages along their banks.

INDIA: Overview of CWC Flood Monitoring Sites

Central Water Commission is the only agency doing flood forecasting in India. As per CWC’s Flood Forecasting website[i] the Data Flow Map has information about 226 Flood Forecast Sites in the country comprising of 166 Level Forecast Sites and 60 Inflow Forecast Sites. It also monitors 700 Flood sites, information made available through List Based Exploration and Hydrograph View, but no flood forecasting is done for these sites.

In order to better understand the CWC’s flood monitoring and forecasting work, SANDRP has published report of CWC’s Level Forecast, Inflow Forecast and level monitoring sites in 5 zones of North India[ii], North East India[iii], East India[iv], South India[v] and West India[vi].  Through this report, we have presented all the data at one place with links to separate zone wise reports with detailed description.

Overview of CWC’s Flood Monitoring & Forecasting in North East India

Central Water Commission (CWC) measures and monitors water level at 700 hundred Flood Forecasting site in the country. It publishes this information on its Flood Forecast website[I]. The website has three ways to get this information: Data Flow Map, List Based Exploration, and Hydrograph view. The Hydrograph view provides information for past 72 hours, supposed to be updated every hour. This is in addition to the list of current forecasts.

As per the website the Data Flow Map has information about 226 Flood Forecast Sites in the country comprising of 166 Level Forecast Sites and 60 Inflow Forecast Sites. It also monitors 700 Flood sites, information made available through List Based Exploration and Hydrograph View.

In order to better understanding the CWC’s flood monitoring and forecasting work, in this article we have given state wise list of CWC’s Level Forecast, Inflow Forecast and level monitoring sites in North East India. For better understanding, we have also included part of West Bengal that is in Brahmaputra basin here, in addition to the 8 North Eastern states. Similar report has been published for North India[II] and we hope to publish reports covering other regions of India too.

SOUTH ASIA 2017: MISS YOU, RIVERS & FISH! As Dams and Water sharing dominate

India-Bangladesh-Myanmar face big quake threat A giant fault in the earth’s crust in one of the world’s most densely populated areas could kill tens of millions of people, scientists have warned according to a new paper in the journal Nature Geoscience. Researchers placed hundreds of highly accurate GPS receivers in locations across India, Bangladesh and Myanmar and monitored them over a ten-year period. Now the scientists fear the location is home to a mega-thrust fault which could unleash a 8.2-9.0 magnitude earthquake. More than 140 million people live within a 60-mile area of the potential disaster zone in Bangladesh. The scientists, led by Dr Michael Steckler from Columbia University published their findings in the journal Nature. This is also a warning against major interventions in the North East India. http://www.indiaspend.com/cover-story/india-bangladesh-and-myanmar-face-big-quake-threat-99557, July 19, 2016, http://thenortheasttoday.com/earthquake-of-9-0-magnitude-could-be-unleashed-anytime-from-a-major-fault-underneath-bangladesh/, July 22, 2016, http://www.nature.com/ngeo/journal/vaop/ncurrent/full/ngeo2760.html  Continue reading “SOUTH ASIA 2017: MISS YOU, RIVERS & FISH!

East India Wetlands Review 2017: West Bengal Bent On Destroying World’s Largest Natural Sewage Treatment Plant

The East Kolkata Wetlands (EKW) are unique yet complex system of natural and human-made wetlands in West Bengal. The wetlands cover 125 sq km comprising of salt marshes, salt meadows, sewage farms and settling ponds. They are used to treat Kolkata’s sewage, and the nutrients contained in the waste water sustain fish farms and agriculture.

Devised by local fishermen and farmers, these wetlands served, in effect, as the largest natural sewage treatment plant (STP) for the city. And using the purification capacity of wetlands, Kolkata by transforming nearly one-third of the city’s sewage into a rich harvest of fish and fresh vegetables daily, has pioneered an environment-friendly system of sewage disposal. Because of this, the EKW were designated a “wetland of international importance” under the Ramsar Convention on August 19, 2002. https://en.wikipedia.org/wiki/East_Kolkata_Wetlands

However for past many years, these wetlands are under threat due to exponential expansion of real-estate projects. Recently illegal landfills are on the rise and unprecedented land development and urbanization have been creating concerns about the impact on EKW environment. 2017 has seen the situation turning only worse for EKW.

Brahmaputra basin faces unprecedented flood wave in Aug 2017

In the morning of Aug 11, 2017, while checking my daily morning routine sites, I saw the sudden appearance of purple patch (signifying rainfall in access of 175 mm rainfall in previous 24 hours) on NASA daily rainfall accumulation map for Indian subcontinent.[i] The purpose  patch covered parts of the West Bengal, North East Indian and Bangladesh. I was taken aback, but it was not very unusual to see in the peak of monsoon. So as we usually do, I took a screenshot and put up on SANDRP FB page with a warning that this could lead to floods. I did not realize that this was the beginning of an unprecedented wave of floods for these regions that may extend to Ganga basin as I write this. Such purple patches generally disappear in 24 hours, since the rains do not last to long. However, in the case of current phase, not only the purple patch has last now for 42 hours, it has extended  to the west, all along India Nepal region along the southern boundary of Nepal.   Continue reading “Brahmaputra basin faces unprecedented flood wave in Aug 2017”

Retracing Her Path 2: A Journey along the Teesta River in W Bengal

Guest Blog by Gauri Noolkar-Oak

The minute I crossed over the Indo-Bangladesh border into India at Chengrabandha, the atmosphere changed instantly; more briskness, more people and more English and Hindi surrounded me. I also spotted posters of Baahubali 2, and a few flags of Bhartiya Janata Party fluttered at the local bus station of Chengrabandha. I set out for Mainaguri, and through the pitter-patter of a weak drizzle, as the first tea plantations came into view.

River Sand Mining in India in 2016

For past many years, incidents of illegal river sand mining across the country are on the rise. Given its resultant and adverse impact on river system and dependent communities, various state and central governments continue to go through the motions of devising a mechanism for judicious excavation of this minor mineral. But there seems no will to achieve compliance. At the same the time, people and concerned groups affected by illegitimate riverbed mining practices are approaching judiciary seeking legal intervention to curb the unsustainable mining of the natural resource.   

In this backdrop, continuing[1] tracking of this issue (like in 2015) SANDRP is providing an overview of various aspects related abstraction of the finite grit material from the rivers through a three part blog series. The first part of the series presents description of the most of the illegal riverbed sand mining incidents that have taken place in different Indian States through the year 2016. The second part of the blog gives account of the measures taken by governments at States and Central level to check the pilferage of this natural resource. The third part will highlight on the legal interventions by respective courts including Honorable Supreme Court (SC) and National Green Tribunal (NGT) to regulate unscientific quarrying of riverbeds.

The dam induced flood disaster could only increase since we refuse to learn any lessons:

SANDRP Blog A tale of two dams: Is Bihar’s unprecedented flood an avoidable man-made disaster? Is the unprecedented water levels of Ganga that has flooded Bihar and UP an avoidable flood disaster?
