Guanacaste, Costa Rica: The Struggle for Water Amid Real Estate Expansion

• Guanacaste, Costa Rica's driest province, faces a severe water scarcity crisis driven by rapid, unregulated real estate development and luxury tourism.
• Foreign speculation and "lifestyle migration" have led to high vacancy rates in coastal housing, straining local resources while marginalizing residents.
• Aquifers in the region are suffering from overuse and seawater contamination, while infrastructure underinvestment has caused declining water quality.
• Local communities have launched organized resistance against projects that prioritize tourist developments over fundamental human rights to water.

Drivers of Crisis

• A surge in luxury villas, gated neighborhoods, and vacation homes—often unoccupied for much of the year—has transformed the coastal landscape.
• Development is fueled by a desire for exclusive, "secluded" retreats, which economically and socially detach from local populations.
• Profits from these service-heavy developments frequently flow abroad, leaving local residents to rely on low-wage roles while facing housing and water shortages.

Environmental Impact

• Climate change is intensifying the region’s natural droughts, putting additional pressure on already strained tropical dry forest ecosystems.
• Lack of transparent, reliable data on aquifer capacity has allowed for thousands of unauthorized wells to be drilled.
• Mangrove ecosystems have been destroyed to accommodate large-scale projects, further destabilizing the environment.

Governance and Conflict

• Despite the 2020 constitutional recognition of water as a fundamental human right, policy implementation favors private interests.
• ARESEP data from March 2026 confirms widespread water contamination, including fecal coliforms, linked to aging infrastructure.
• Community-run water management systems are increasingly threatened by private sector takeover and government reliance on private financing.
• Notable flashpoints of resistance include:
  • Sardinal: Protests against the diversion of inland water to coastal luxury projects.
  • Potrero: Efforts to maintain autonomy of community-run aqueducts.
  • Santa Cruz: Long-standing opposition to the exploitation of the Nimboyores aquifer.
  • Marbella: Ongoing conflicts regarding illegal wells and the intimidation of community activists.

Global Context

• The 2026 UN Water Conference report, Global Water Bankruptcy, highlights that Guanacaste is a microcosm of a broader, global pattern where intensive resource extraction and population shifts threaten the viability of local aquifers.
