Thirty years after the Pak Mun dam was inbuilt Thailand, the standard approach of fishing within the Khong Chiam district has fully stopped because the dam blocks the seasonal migrations of a variety of fish.
Many males have needed to depart their properties to seek out work elsewhere as a result of they couldn’t fish or farm regionally anymore, whereas their wives are sometimes left alone to take care of their kids. Folks with disabilities and the aged haven’t been included in compensation and livelihood rehabilitation programmes, regardless that they’re among the many teams most affected by modifications in mobility, entry to water and meals techniques.
My group and I’ve been documenting the knock-on results of this dam improvement by finishing up interviews with individuals dwelling in these communities. My analysis highlights that if the environmental penalties of dam constructing had been higher predicted and monitored, numerous the continuing disruption might have been prevented.
In 1982, a environmental influence evaluation for the Pak Mun dam was ready by a group of Thai engineering consultants. Environmental influence assessments are used to determine, predict and consider the doable penalties of a proposed challenge earlier than it begins. They’ve been in use for a few years, however some governments bypass their suggestions.
If accomplished extra rigorously, this evaluation for the Pak Mun dam might have anticipated these damaging social and environmental penalties and may need influenced selections concerning the constructing and upkeep of this dam. However in line with analysis, this influence evaluation was weak.
One examine famous that the environmental impacts of the dam – primarily on fish – had been both unquantified or understated. One other examine famous that the positioning location had moved and that required a brand new evaluation fairly than replying one the primary one. The boundaries of this evaluation has led to ongoing contestation between the central and provincial authorities and the affected communities and activists.
That is removed from the one instance of an absence of consideration for the long-term knock-on results of dams on communities and nature. In 2025, the Indian authorities allegedly fast-tracked the development of the large Sawalkot hydropower challenge on the Chenab river with out conducting any environmental and social influence evaluation.
Massive-scale tasks like this have an effect on thousands and thousands of individuals and the atmosphere round them. With out ample influence assessments, they proceed with out establishing simply what impact they may have on the encircling panorama, nature and communities. In consequence, any damaging penalties usually are not simply prevented.
Whereas this new political dynamic of circumventing influence assessments is worrying, social and environmental influence assessments are useful if used appropriately. As a part of my analysis, I’ve spoken to dozens of influence evaluation consultants and teachers to evaluate the established order.

By 2033, the worldwide marketplace for environmental influence assessments may very well be price an estimated US$5.8 billion (£4.3 billion). Whereas the influence evaluation course of is seen as useful by consultants and teachers, a few of our interviewees frightened that expensive suggestions typically get misplaced within the technique of challenge implementation as soon as the doc has been produced.
Ideally, influence assessments ought to be primarily based on scientific data and contain substantial public participation and located neighborhood data, particularly by those that are liable to antagonistic penalties, in addition to clear accountability mechanisms.
In observe, there are issues. Impression evaluation is a political course of; it isn’t primarily based purely on proof and scientific info. It’s influenced by the economics of dam constructing. Dams are sometimes additionally necessary symbols of nationalism, in order that they maintain excessive political standing.
With out guaranteeing systematic follow-up to an influence evaluation, it may well merely turn out to be a paper chase to safe a improvement allow. With extra consideration, the “afterlife” of influence assessments might be way more efficient.
Who’s accountable?
Who, when it comes to accountability, ought to be held accountable for shortcomings within the implementation of influence evaluation plans? Ought to it’s the federal government that ought to be accountable for ensuring the totally different rules and norms are adopted?
Ought to it’s the business banks, improvement banks and bilateral donors (comparable to overseas support supplied by the UK authorities’s International Commonwealth and Improvement Workplace) that fund tasks who ought to monitor the necessities that they had elaborated? Or ought to it’s the personal sector?
My analysis exhibits that the duties lie with all of those events.
In most international locations, many of the info and knowledge is managed by the proponents of constructing the dam. Venture managers and engineers could also be suspicious of exterior influence assessor consultants, so they don’t all the time share the related info.
Civil society, starting from native marketing campaign teams and activist to non-governmental organisations, have pushed for requirements and legal guidelines that guarantee guidelines are adopted throughout and after any influence evaluation. For this to work, influence assessments must be dynamic so responses to doable altering penalties can change.
When environmental coverage and instruments like influence assessments are being questioned, it’s much more necessary to create a coverage course of that ensures long-term accountability for influence assessments and stop additional losses and damages to the communities and the atmosphere.
