On Oct 29, 2018, another landslide dam blocked the path of Yarlung Tsangpo Dam, reportedly at the same location as the Oct 17,2018 landslide dam[i]. It breached on Oct 31, without any reported major calamity, but these repeated occurrences, twice in two weeks and third time in ten months (if we include Dec 2017[ii] landslides) raises a lot of questions. The silence of government of India institutions about the possible causes or other analysis, including by Central Water Commission, Union Ministry of Water Resources, National Disaster Management Authority or even National Remote Sensing Agency has, as expected, raised questions and speculations in Arunachal Pradesh.

In a mountain village in southwest China’s Sichuan province, authorities have demolished seven small dam projects this year along a river to clear illegal developments in a new nature reserve. The demolition is part of a nationwide programme to close hundreds of tiny and often ramshackle dams and turbines and bring order to China’s massive hydropower sector after years of unconstrained construction.
The dams sat on an unnamed tributary of the fierce and flood-prone Dadu river, which feeds into the Yangtze, Asia’s largest and longest river, where the government says the “irregular development” of thousands of small hydropower projects has wrecked the ecology. But green groups say the campaign will not necessarily save the environment because it will not affect big state hydropower stations, which they say have caused the most damage.
On the 48 km Zhougong, authorities have already demolished small projects built in nature reserves or encroaching upon new “ecological red lines” drawn up to shield a quarter of China’s territory from development.
The government says small dams have disrupted the habitats and breeding patterns of many rare species of fish, although green groups argue the damage wrought by bigger dams is more severe, with entire towns and ecosystems submerged in water, which they say increases the risk of earthquakes, landslides and even climate change.
In its latest report, the Comptroller and Auditor General (CAG) has questioned implementation of sixteen National Irrigation Projects. Before this, the CAG has held mismanagement in dams’ operation responsible for Chennai floods in 2015. Both these reports are available on its website now.
The CAG report on National Irrigation Projects, tabled in Parliament on July 20, has revealed that sixteen major multi-purpose water projects, taken up on an expeditious basis about a decade ago, are nowhere near completion, with no work being undertaken in as many as 11 projects despite the incumbent govt’s much-wanted focus on improving irrigation facilities in the country.
The report also mentioned that out of the 16 projects, undertaken under the Accelerated Irrigation Benefits Programme (AIBP) in Feb 2008, only five projects with estimated irrigation potential of 25.10 lakh hectares were under implementation and even these projects suffer from 8 to 99 per cent shortfall in physical progress, the CAG said. The remaining 11 projects with estimated irrigation potential of 10.48 lakh hectares are yet to commence and are at different stages of approval.
How is development possible along with environment protection? There are two kinds of answers possible to this question. The standard kind of reply would try to provide a list of options that are available to a given development need.

After reviewing status of India rivers, SANDRP presents an account of research, studies and important reports on erratic monsoon, climate change, floods which all are severely affecting the rivers, their aquatic life and livelihood of dependent communities.
Rivers and Monsoon
Number of rainy days falling across river basins in India The study has found that number of rainy days is falling across river basins in India and rainfall intensities are seen to be increasing. The analysis determined changes in heavy precipitation and peak flood for seven river basins in India—Krishna, Godavari, Mahanadi, Narmada, Cauvery, Sabarmati and Brahamani and Baitarani. For the study, data pertaining to daily flows for about 30 odd years and precipitation for 61 years (from 1951 to 2012) were analysed.
The analysis also said the rivers which flow from west to east direction (in India) have more rainy days compared to those which flow towards the west. The study also held that anthropogenic activities (construction of storage reservoirs, diversions, urbanization, land-use change, and soil and water conservation measures, among others) have probably affected the generation of peak floods in the rivers of India. http://www.livemint.com/Politics/c7v8oXmsMDHIldjDv9k6lK/Number-of-rainy-days-falling-across-river-basins-in-India-s.html (Live Mint, 27 April 2017)
In this comprehensive article Mumbai-based author Vaishnavi Chandrashekhar throws the light on the plight of Uraban Rivers. “Rivers and streams have borne the brunt of the recent urban explosion in India, a nation whose population has nearly doubled in the last 40 years to 1.35 billion. Unplanned growth has led to the use of water bodies as dumping grounds for sewage and industrial effluent. According to CPCB, 63 % of the urban sewage flowing into rivers (some 62 billion liters a day) is untreated.
In addition, riverbanks, wetlands, and floodplains have been claimed over time by infrastructure, slums, offices, and housing developments – all of which has narrowed natural river channels and distorted flow, greatly reducing the ability of India’s rivers to buffer flooding. It also has taken a toll on biodiversity. http://e360.yale.edu/features/dying-waters-india-struggles-to-clean-up-its-polluted-urban-rivers (Yale Environment 360, 15 Feb. 2018)
The current ongoing episode of Muddy Siang River water in Arunachal Pradesh is due to landslides in the upstream Tibet, triggered by the earthquakes starting on Nov 17, 2017 or possibly earlier. This is revealed by the satellite pictures and work of two researchers, first published in Arunachal Times on Dec 21, 2017[i]. These landslides are partly blocking the Siang flow and could lead to massive floods in the downstream Arunachal Pradesh and Assam any day.
A similar event in year 2000 led to sudden, massive floods in Siang River in Arunachal Pradesh on June 1, 2000. That episode, like the current one, started about 53 days before the floods, on April 9, 2000 due to landslides along a tributary of Yarlung Tsangpo, as Siang is known in Tibet.

Protests and controversies around Pancheshwar Multipurpose Project (PMP) are only growing louder and wider. While Expert Appraisal Committee (EAC) Rivers Valley Project in unnecessary hurry considering the project tomorrow (05 Dec. 2017) http://environmentclearance.nic.in/writereaddata/Form-1A/Agenda/2811201745T4GD5I10thAgendaEACHydro05122017.pdf
Villagers and local groups people also continue raising their concerns and objections against 5040 Mw dam project. Today, scores of villagers, environmental groups including regional political party have protested at Jhulaghat in Champawat, Pithoragarh, Almora and in Delhi demanding EAC to listen to the voices of local people and groups.

Assam, Arunachal and the North East India, West Bengal and Bangladesh are riverine entities in many ways. Ancient rivers flowing through this landscape have moulded not only the mountains and the silt-heavy banks, but cultural identity of the region itself. Rivers permeate through the literature, folklore, songs, poems, cuisine, even dressing… Bhupen Hazarika, the Bard of the Brahmaputra, likened the red ripples of the Assamese Gamcha (red and white stole) to the braided filigree of the Red River. When Guwahati University opened on the banks of Luit, Hazarika sang “Jilikabo Luiter Paar”..Banks of the Luit will Shine. Rivers stood for revolution as they stood for Love.. Jyoti Prasad Agarwal wrote “Luitar Parore Ami Deka Lora.. Moribole Bhoi Nai.” (“We are the youth from the banks of the Luit/ We are not afraid of death”). Older poets like Parvato Prasad Baruah wrote entire books full of poems of Luit and today modern poets in Assam like Jeeban Narah link their creative processes inextricably to rivers.

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.
