Documenting the ecological devastation caused by hydropower development in the Himalayas, Himdhara Environment Research and Action Collective in the month of the ‘World Environment Day’ has released a report titled “The Hidden Cost of Hydropower” that highlights the risks associated with hydropower construction, especially in Himachal Pradesh. Over the last few years increasing evidence has emerged that hydropower production may not be so ‘clean and green’ after all. This document compiles primary and secondary evidences of the impacts triggered by underground construction for run of the river (ROR) hydropower projects.highlighting the issues of environmental hazards and risks involved.
Echoing the fragility of the Himalayan region due to geological instability and climate change related disasters like flash floods and cloud bursts, the report highlights the role of construction activities that accentuate this fragility. “A report of the state’s own disaster management cell says that around 10 Mega hydropower stations are located in the medium and high-risk landslide area”, states the document. The report explains that the magnitude of underground component of the civil work in hydropower projects involving blasting and dynamiting exacerbate existing vulnerabilities. These impacts are yet to be adequately studied and understood.
Visuals and testimonies of affected people from project sites in Kinnaur, Kullu and Chamba falling in the Satluj, Beas and Ravi basin collected over the years have been used to show the impacts. Case studies like that of the Parbati II, Karccham Wangtoo, Kashang and Bajoli Holi projects illustrate how landslides, drying up of springs, damages to houses, farms and forests have made difficult the lives and livelihoods of the people in the project area.
The report finds that the existing studies available on these impacts are inadequate or biased in favour of the hydropower producers, with economics as the main concern. Environment Impact Assessment reports of hydro-power projects gloss over the geological & seismic vulnerability of the project sites, with an explanation that the ‘hurdles’, ‘surprises’ and ‘in competencies’ of the mountain geology would be handled at a later stage, if and when they occur. ‘Scientific’ linkages become difficult to establish later, and during EIAs, the concentration is to only rush through the studies to get ‘clearances’.”They say there is no scientific evidence that the landslides are because of project activities and so we cannot claim compensation in case of cracks in the houses or damage to fields”, according to Ramanand Negi of Urni Village located in the affected area of the Karchham Wangtoo project and now sitting on a huge landslide.
The report also refers to Audit reports of the Comptroller Auditor General to shows how the costs of these ‘surprises’ are borne by the affected people or transferred to the public exchequer The costs that producers have been forced to bear have led to financial losses and bad loans and cumulatively a slump in the hydropower sector over the last few years. According to the report, “The contribution of hydropower sector today to the country’s total electricity production has halved from 25% to 13% in the last decade. Where this state of hydropower industries was an opportunity to review hydropower policy and the sector’s viability, the report of Parliamentary standing committee on energy that reviewed the performance of hydro projects in 2018 turned a blind eye to environmental impacts and safety norms”. Based on the committee’s recommendations the Ministry of Power issued an order in March 2019 recognising hydropower projects with a capacity of more than 25 MW as ‘renewable’ source of energy, thus eligible for further subsidies. Himdhara’s report, however, brings out that hydroprojects do not deserve the ‘green’ tag and the government should stop further subsiding the sector, especially large projects.
The report also identifies the institutional failures of the Central Water Commission, the Central Electricity Authority that are supposed to assess the Detailed Project Reports, give techno-economic clearances and monitor the progress and reasons for delay in projects; the Ministry of Environment that has blindly granted environment and forest clearances overlooking the above impacts and non-compliance; the State Directorate of Energy and State Disaster Management Authority, who have failed to fulfil their regulatory roles and ensure that there is no negligence.
An independent scientific review of the immediate or long-term implications of construction work for hydropower development in the Himalayas should be commissioned. Citizens engagement, Public consent mechanisms needs to be strengthened, and a grievance redressal process needs to be put in place.
See why we must start afresh regarding our ways of living, Otherwisw we will see a flattening of the Himalayas:
