About Uttarakhand Rivers

Uttarakhand_Drainage_map

The water quality of Uttarakhand‘s rivers is basically good, especially in the upper reaches. Downstream of some large settlements and in the lower reaches in the Himalayan foot hills the water quality suffers due to the release of untreated sewage and industrial effluents. But the state‘s ambitious program to build 450 hydro power projects threatens the survival of the river ecosystems and the lives and livelihoods of people who live  in these river valleys.

DRP: 3 April 2017 (India: Power Surplus & Exporter, Record Solar-Wind Growth, Need Not Push Destructive Hydro)

Power surplus, power exporter India, with record solar& wind wind generation trend, why push more destructive hydro projects According to power ministry statement on March 29, 2017, India for the first time became NET EXPORTER OF ELECTRICITY during 2016-17, it exported 4% more power during last 11 months (April-Feb), that what it imported from Bhutan. At the same time, power plants, on a national average, are opera ting at roughly 60%, down from nearly 65% in 2014-15.

Meanwhile, the Cabinet Committee on Economic Affairs has approved the amendments in the Mega Power Policy to push 31 GW stuck projects entailing an investment of Rs 1.5 lakh crore. The stuck projects in mega power policy include hydro projects of above 350 Mw in designated states (J&K and eight NE states) and above 500 Mw in other states.

Amid this, New and Renewable Energy Ministry has added over 5400 Mw wind energy capacity in 2016-17 against the target of 4000 Mw. This year’s achievement surpassed the previous higher capacity addition of 3.423 Mw achieved in the previous year. The leading States in the wind power capacity addition during 2016-17 are Andhra 2190 Mw, followed by Gujarat 1275 Mw and Karnataka 882 Mw.

In the last couple of years, India has not only seen record low tariffs for solar power but wind power too has seen a significant drop in tariffs. The onshore wind power potential alone is about 302 Gw. Preliminary estimates show the Gujarat coastline has the potential to generate around 106,000 Mw of offshore wind energy and Tamil Nadu about 60,000 Mw.

West Bengal Rivers Profile

About West Bengal 

Area: 88752km2; 20 districts; Population- > 91 million Topography: Mountains, Plateaus and Plains.

About West Bengal Rivers

The state of West Bengal, a land of many rivers, covers an area of about 88,752 km2 and is the home of more than 90 million populations as per census of 2011. The Ganga divides the state into two unequal hubs: the North and South Bengal. The state has been divided into 20 districts, the seven districts are within North Bengal and remaining 13 districts are in South Bengal. West Bengal is the only state of India that extends from the Himalaya in the north to Bay of Bengal in south. It offers wide topographic diversity and intricate drainage network of 29 basins. The south Bengal can further be subdivided into two geographical units taking Bhagirathi-Hugli river (the western distributary of the Ganga) as the demarcating line. The western part is called Rarh Bengal and the eastern part is described deltaic Bengal. The rivers of West Bengal have been divided into five groups: i) the rivers of North Bengal; ii) the Ganga-Padma system; iii) the Bhagirathi- Jalangi-Churni system; iv) the western tributaries to Bhagirathi and v) the tidal creeks of Sundarban.

DRP: 20 March 2017 (South India Reeling Under Severe Drought)

The drought has extended its grip in the South, with the South-West (S-W) monsoon falling significantly short and the North-East monsoon proving a total failure. Reeling under the impact of failed monsoons, Kerala, Karnataka, Tamil Nadu and Puducherry have declared themselves as drought affected. Kerala and Karnataka, which are the worst affected, are already contemplating actions such as cloud seeding to tide over the situation.

In Kerala, the S-W monsoon deficit stood at -34 per cent, and the North-East monsoon, -61 per cent. Similarly, in Tamil Nadu, the deficits were -19 per cent and -62 per cent (North-East monsoon). For Coastal Karnataka, the shortfall stood at -21 per cent and -63 per cent, respectively. Drought-like conditions are also prevailing in parts of Andhra Pradesh and Telangana.

Water levels in key reservoirs in the region are at their lowest. The water tables have declined further even as the civic administration in many cities, small towns and panchayats has been increasingly tapping groundwater to ensure supplies. The situation is so dire that the Kerala govt has directed PepsiCo to cut down drastically on the use of groundwater for its Palakkad plant. Traders in Tamil Nadu are also boycotting these fizzy after claims that foreign firms are exploiting the country’s water resources.

DRP: 27 Feb 2017 (Urgent Need To Review Impacts Of Farakka Dam: Experts)

During a global seminar held on Feb. 25-26, 2017 in Patna experts from across the country have advocated an “urgent review” and comprehensive study of the Farakka dam to revive the Ganga river. The experts were discussing various concerns facing River Ganga and the possible solutions for them. The seminar titled as “Incessant Ganga” was organised by Bihar’s Water Resources Department, almost week after, Bihar CM Nitish Kumar has openly termed the barrage as genesis of floods in the State. Speaking in the program, the CM again expressed deep concerns behind receding water flow in the Ganga and increasing silt deposit due to Farakka dam.

Speaking during the seminar, environment expert Himanshu Thakkar the coordinator of SANDRP advocated urgent need for review of Farakka barrage claiming that it has failed to fulfill any of the purpose – irrigation, hydro electric power, water supply – of the barrage for which it was built. As per, Himanshu Thakkar the dam was built to maintain the navigability of Kolkata port. 

Thakkar also suggested that the gates of Farakka be opened during monsoon to mitigate the intensity of floods in Bihar. As per Thakkar there was an urgent need for a comprehensive study of the Farakka barrage to find out its achievements or whether the barrage fulfilled its objectives. The committee constituted for study must include the Centre, Bihar, West Bengal and all states having Ganga, he said adding that a study should be made on the social and livelihood impact of the barrage, how it affected people’s lives, whether its existence was justified and cost-benefit assessment among other issues.

Finally the Oroville Dam spillway damage has turned into a disaster. Report at this time (01:00pm, Feb. 13, 2017) finds dam level rising about 1 feet above the danger level. Water currents have started pouring out all over and around the emergency spillway which has never been put in use for last half a century. Meanwhile, more water is gushing in the dam reservoirs due to recent heavy rainfall in catchment areas upstream.

DRP: 30 Jan 2017 (After 31 years, SC transfers Ganga case to NGT without achieving clean river)

SC transfers PIL on cleaning Ganga to NGT In a major development, after monitoring Ganga cleaning work for last 31 years and without achieving any cleaner river,  the Supreme Court on January 24, 2017 wrapped up a PIL on cleaning of river Ganga and sent it to the National Green Tribunal (NGT) for more effective adjudication. The apex court had been monitoring the issue for 31 years. A bench of Chief Justice J S Khehar and Justice N V Ramana said that since issues relating to municipal solid waste and industrial waste were already being heard by the NGT on a day-to-day basis, all other issues relating to sources of polluting the river should also be heard by the NGT.

The bench said that the tribunal will be required to submit an interim report to it every six months, only to give an idea about the progress made and difficulties, if any. It also granted liberty to the petitioner, environmentalist M C Mehta, to approach the court if he had any grievances in consonance with the law.

During last week hearing (January 17, 2017), the SC bench has directed the government to file a report on the construction and functioning of STPs alongside the river, which runs through five States.

It has been almost two years after the SC has voiced scepticism about the government’s self-proclaimed promise to clean up the Ganga River. Before this, in 2014, the apex court had voiced its reservations about the various efforts over the decades to return the Ganga to its pristine self, once even saying that it “does not expect Ganga to be cleaned up even after 200 years.”
