A Miracle in the Desert

Three hundred kilometers south of Lima, sandwiched between the coast and the Andean foothills, sits the department of Ica, one of the driest regions in the world. Between the cold upwelling from the Pacific, the relentless solar radiation, and its position along the 14th parallel, Ica is almost completely devoid of rainfall. It averages less than two millimeters annually. Yet despite the extreme aridity, the Ica Valley, a ribbon of fertile land surrounding the region’s capital city, has become the crown jewel of an enormous agribusiness empire. It accounts for one out of every five dollars grossed by Peru’s $15 billion industry. The corridor specializes in the intensive cultivation of export-oriented cash crops, and has helped facilitate Peru’s rise as a global agricultural powerhouse. Today, the nation tops the charts for the export of table grapes, avocados, blueberries, cotton, and asparagus.

Historical Context

The Ica Valley rose to global prominence during Peru’s agricultural revolution, which shifted the nation from majority subsistence farming to an international agro-exporter. The overhaul began in the 1990s as part of a larger effort by then-President Alberto Fujimori to stabilize and revitalize Peru’s struggling economy through neoliberal reform and foreign investment. Out of the rapid growth and innovation of the era came the dream to convert a desert into a global breadbasket. For thirty years, drip-irrigation and hydraulic engineering have sustained the 2,000 square kilometers of desert land that supply American, European, and Asian markets with more than 700,000 tons of choice produce every year.

A Hydrological Deficit

Despite these achievements, the prosperity of the Ica Valley may be a mirage rather than a miracle, one predicated on a rapidly depleting supply of groundwater from the Ica-Villacurí Aquifer. The crops that Ica sustains require constant and generous irrigation to withstand desert conditions. For example, asparagus, the primary crop cultivated in Ica, requires between 15,000 and 17,000 cubic meters of water per hectare per year. In 2013 alone (the last year the industry made its reports public), the region cultivated 10,000 hectares of asparagus, draining upwards of 170 million cubic meters to sustain just the one crop. As of December 2025, the Ica Valley harbors one of the fastest-draining aquifers in the world, hemorrhaging the equivalent of between 117 and 325 Olympic swimming pools of water every day. Although the aquifer has been in emergency status since 2008, little has been done. Since 2010, export revenues have sextupled, an additional 100 square kilometers of land has been brought under irrigation, and water use has increased by a further 30%.

Evolution of the Regulatory Framework

Beginning in the mid-2010s, the rapid expansion of agricultural infrastructure has outpaced the implementation of regional drilling restrictions. Between 2012 and 2025, the total number of wells rose from 1,700 to an estimated 2,116, out of which only three in ten are licensed. Rather than strictly enforcing its own mandates, the National Water Authority of Peru (ANA) has offered avenues for growers to bypass environmental safeguards in an effort to prioritize the nation’s economic interests. In 2015, for instance, the ANA passed the Water Amnesty Act, which allowed select users with unauthorized wells to obtain temporary permits while processing their formalization and paying a fine calculated per irrigated hectare. Essentially, the act allows companies that violate drilling bans to continue pumping water from illegal wells by paying fines that amount to only a fraction of the resource’s actual value. For example, Beta, one of the region’s largest conglomerates, paid just 169,316 soles (about $50,000) to legalize 15 illegal wells that had already pumped hundreds of thousands of liters of water before being discovered.

Regional Distribution and Quality Impacts

Although experts have yet to estimate a precise Day Zero (the date when the region’s water supply will have been completely depleted), Ica’s residents have already begun to experience the consequences of the overdraw. Aquifer exhaustion causes smallholder and municipal wells to run dry, and forces the upwelling of highly saline groundwater, which pollutes potable stores. In the Villacurí district, nearly half of all wells now yield water with salinity levels too high for either irrigation or human consumption. In the Lanchas plains, potable groundwater cannot be accessed until as deep as 30 meters. In many areas of rural Ica, the water crisis has already forced many locals to switch away from traditional staples and to cultivate salt and drought-tolerant crops like paprika or abandon farming altogether. In the city of Ica, piped water access is steadily declining; already, 35,000 residents lack running water and must buy it from private tankers for triple the municipal price. Salinization also threatens the city’s drinking water: each year, the aquifer’s salt concentration increases by 0.1 deciSiemens per meter (dS/m), and in some neighborhoods, the supply has exceeded the World Health Organization’s recommended 1.5–2.0 dS/m levels, leading to increased risk of hypertension and kidney deterioration.

A Balancing Act

The present water crisis in the Ica Valley raises broader structural questions regarding the long-term sustainability of the export-led, extractive model that has historically served as the backbone of Peru’s economy. As of 2026, several of Peru’s top industries are extractive operations: mining, natural gas exploitation, commercial fishing, and agriculture. While the expansion of these industries has generated billions in revenue and attracted significant foreign investment, it has not succeeded in achieving robust local benefits. As seen in Ica, these models establish economic pipelines that funnel resource wealth directly from mining pits and into global markets, but bypass the local citizens, infrastructure, and economies that bear externalities of their extraction.
