What You Can Do About San Miguel’s Water Crisis

Río Laja

By Robin Loving Rowland

According to a study done by geological engineer Marcos Ortega, Ph.D., our Rio Laja is the primary source of drinking water for 500,000 people, as well as for agricultural and industrial uses. In fact, 85 percent of this water goes for agricultural production, most of which is exported. The study shows that most of this water has been depleted over the past 60 years, increasing the concentrations of arsenic and fluoride, causing severe health effects in rural villages and more recently in the main urban centers. Increasing concentration of sodium is affecting soil productivity and plant growth, causing land to be abandoned. Water quality does not meet certain minimum standards in most of the basin. The study concludes that human actions are impairing the long-term renewability of fresh water here. Water planning and decision-making are not democratic but controlled by farmers with political power. To avert this water resources crisis, social participation is needed.
