Spanish farmer Miguel Moreno was an early adopter of so-called cover crops. Spain's drought-hit olive oil production slumped to 663,000 tonnes last year, less than half the average of 1.45 million tons recorded in the previous four harvests, according to the government. In January, it began subsidising farmers who use cover crops as part of the new Common Agricultural Policy (CAP). She said the company was pushed both by customers such as Walmart in the U.S. and by regulation to buy olive oil from producers using sustainable practices. Ecology professor Manzaneda is also coordinator of EU-funded project SOIL O-LIVE and is testing methods for coaxing Albacete's degraded earth back to health.
