Can anyone hear the socioeconomic and environmental alarm bells on Lesotho Highlands Water Project?

Recognised as one of the most outstanding engineering achievements of the last century, the Lesotho Highlands Water Project (LHWP) is indisputably an engineering marvel that was also hailed for the profound economic benefits it would bring to both Lesotho and South Africa.

It has instead become internationally notorious for its devastating socioeconomic and environmental impacts on highland and downstream communities. But this is hardly ever highlighted as much as the engineering achievements or the perceived economic and service delivery benefits for the two countries.

Phase 1 of the project, involving the construction of Katse Dam and Muela Hydropower Station (Phase 1A) and Mohale Dam (Phase 1B), dispossessed more than 30,000 Basotho of their cropland and grazing land. The expropriation of land was executed without equitable/fair compensation and proper livelihood restoration plans.

The project submerged 1,500 hectares of arable land, 1,900 ha of cropland and more than 5,000 ha of grazing land, exacerbating soil erosion and overgrazing as farmers were forced to cultivate on progressively steeper slopes and graze animals in increasingly smaller and condensed areas.

There have been long-term concerns that communities did not get direct economic benefits and/or continued support where such benefits had been provided. Many of these communities are without water, and in some, the water supply from natural springs has been polluted while others have been destroyed due to a lack of maintenance.

Communities are not allowed to access the dam water for household use, irrigation or for livestock to drink. Fishing in the dam was for a long time expressly prohibited until recently. Communities are now permitted to fish with a fishing licence.

"The dam contributed to increasing vulnerabilities, including the risk of HIV infection. Relationships between female residents and construction workers were common, and transactional sex (the exchange of sex for money or gifts) between local schoolgirls and construction workers was rife. HIV/Aids infection rates skyrocketed in construction areas, yet these communities remain without access to basic healthcare services."

"With the social influx and labour migration expected when construction of the dam itself commences, the risk that transactional sex will resume also increases the risk of increased HIV-infection rates, especially among young women. Research has shown that adolescent girls and young women are significantly more at risk from HIV infection due to transactional sex, compared with men and boys of the same age."

These are known facts, to both Lesotho and South Africa, and it is heartbreaking that they have now started the second phase of the LHWP without addressing these residual issues, which violate human rights on many levels.

These violations include unfair evictions and the relocation of indigenous communities from their traditional lands; sexual and gender-based violence being exacerbated by increased labour, including migrant labour required for construction work; and extensive environmental degradation, including water and other critical natural resources on which communities rely for both sustenance and their livelihoods.

Contracts for the construction of Polihali Dam, Phase 2, were awarded in November 2022. There are 36 affected communities in the remote Mokhotlong district where the dam will be constructed.

Hundreds of families will be involuntarily resettled and displaced from their homes and lands, a process that will have significant economic and socio-cultural implications for generations to come. Multitudes stand to lose thousands of hectares of arable and grazing land.

The result is going to be food insecurity, impoverishment and the breakdown of social networks and culture. But this is not being given as much attention as the majestic bridges, the gigantic dam and the beautiful roads that open the highlands to tourists.

Up to this point, the Lesotho Highlands Development Authority (LHDA), the project’s implementing authority, has been implementing advanced infrastructure works (such as the construction of roads and bridges and the erection of power lines) to make way for the construction of the Polihali Dam. There are nine communities that are at the epicentre of these works.

Astoundingly, the governments of South Africa and Lesotho have not learned any lessons from the implementation of Phase 1, because the same mistakes are being repeated:

• Compensation is not being paid or is delayed and inadequate;


• Access to water has been impeded and women are forced to walk long distances to fetch water at times from unsafe water sources shared with animals. Some are forced to collect water from river streams that have been polluted by LHDA contractors;


• There is no access to health facilities – people are forced to walk up to two hours to access the nearest health centre; and


• There are reported cases of sexual exploitation of young women who are forced to sell their bodies for work or for money. With the social influx and labour migration expected when construction of the dam itself commences, the risk and prevalence of HIV in these communities will increase, contributing to increasing vulnerabilities within communities and particularly among women.
