#fertiliser runoff

In the northwestern Spanish region of Galicia, locals have been contending with foul smells, dangerous drinking water and a deteriorating natural environment for years. The alleged culprit: industrial pig farming. "This used to be a paradise," said local environmental activist Manuel Garcia, standing near a pile of waste from nearby pig and chicken farms. "People here, when they had bad harvests, fed themselves with what nature provided. Hunting, fish, frogs." But as pig and chicken farms have expanded over the decades, Garcia has seen his home district of A Limia deteriorate. Pigs produce a staggering 2 tons of urine and feces annually. By comparison, an average dog excretes around 270 pounds (122 kilograms) of waste a year. The waste is rich in nitrates, which can be useful as fertilizer but is harmful in excess. Garcia said nitrate runoff has killed fish and frogs, polluted wells and transformed what he remembers as the lush Lima River into something resembling "a sewage treatment plant." A farmer by profession, Garcia has spent much of his time in recent years raising awareness of the problem. He said much of the pig waste has been dumped without proper precautions. But in July 2025, a group of residents, backed by scientists and lawyers, won a case against regional authorities over unchecked livestock pollution that they say harmed the environment and violated their human rights. The first ruling of its kind in Europe, it could set a blueprint for other communities and may even reach the European Court of Human Rights in Strasbourg, where a decision could force change at the national level. "While the Spanish court granted regional remedies, a Strasbourg ruling could go further by recognizing structural failings," Malgorzata Kwiedacz-Palosz, senior fundamental rights lawyer with ClientEarth, told DW. "[It could require] Spain to implement systemic reforms, including improved nitrate monitoring, farm regulation and water quality protections."
