China-funded hydropower surge in Cambodia exposes neocolonial energy dependency, displacing Indigenous communities while failing to address systemic underinvestment in equitable renewables

The Upper Tatay project threatens the ancestral lands of the Bunong people, who have stewarded the Koh Kong highlands for centuries using rotational farming and sacred forest conservation. Indigenous knowledge systems in Cambodia emphasize riverine ecosystems as living entities, not infrastructure inputs, yet these perspectives are excluded from energy planning. Large dams violate the UN Declaration on the Rights of Indigenous Peoples (UNDRIP), which Cambodia ratified, but enforcement is absent due to weak legal frameworks and corporate-state collusion.

Cambodia’s energy trajectory is shaped by colonial extraction (French-built dams in the 1920s) and Cold War-era Soviet/Cuban infrastructure, which prioritized centralized power for urban elites over rural electrification. The 1990s IMF/World Bank structural adjustment programs privatized state-owned utilities, creating a vacuum filled by foreign investors like China’s Sinohydro. Historical parallels include the 1960s US-backed dams in Vietnam’s Central Highlands, which displaced Montagnard communities and fueled insurgencies—lessons ignored in today’s ‘green’ hydropower rush.

In Laos, the Nam Theun 2 dam—also Chinese-funded—displaced 6,300 Indigenous people and disrupted Mekong fisheries, mirroring Cambodia’s Upper Tatay risks. Contrast this with Japan’s post-Fukushima shift to solar and wind, or Germany’s *Energiewende*, which prioritize decentralized renewables over mega-projects. Indigenous communities in the Andes and Himalayas have successfully resisted dams by invoking ancestral water rights, offering a model for Cambodian activists to leverage international law.

Hydropower dams emit methane from reservoirs (up to 3.5% of global GHG emissions), undermining their ‘green’ label, while sediment trapping reduces downstream fertility—a critical issue for Cambodia’s Mekong-dependent agriculture. Studies show pumped-storage projects like Upper Tatay have lower lifespans (30–50 years) than advertised due to siltation, yet EIA reports often omit long-term viability. Peer-reviewed research from the Mekong River Commission highlights the irreversible loss of biodiversity in dammed rivers, including endangered species like the Irrawaddy dolphin.

Cambodian artists like Vandy Rattana have documented the spiritual rupture of dam-induced displacement, framing rivers as ‘living ancestors’ in Buddhist cosmology. Traditional shadow puppet (*nang sbek*) performances in rural Cambodia often depict water spirits (*neak ta*) as vengeful forces when rivers are harmed, a cultural memory that resonates with modern dam protests. The project’s ‘green power bank’ metaphor clashes with Indigenous animist views of energy as a communal, not commodified, resource.

Scenario modeling by the Asian Development Bank suggests Cambodia could meet 70% of its energy needs by 2030 via solar and wind, yet policy favors hydropower due to Chinese loan conditions. Climate projections indicate Mekong Basin dams will reduce fish catches by 40% by 2050, threatening food security for 60 million people. A just transition would require phasing out fossil fuel subsidies (currently $1.5B/year in Cambodia) and redirecting funds to community-owned microgrids, as seen in Bangladesh’s solar home systems.

Affected villagers in Koh Kong report coercive land grabs, with military-backed security forces suppressing protests, echoing patterns seen in the Lower Sesan 2 dam’s displacement of 5,000 Indigenous people. Women, who bear disproportionate burdens of fuelwood collection, are rarely consulted in energy planning despite their role in household energy transitions. Cambodian NGOs like the *3S Rivers Protection Network* document violations but face harassment, while international outlets amplify elite narratives over grassroots resistance.
