Decreasing water resources is a pressing climate change issue, with crop productivity and food security highly dependent on irrigation. At IPNA-CSIC, Dr Andrés A Borges and his colleagues have launched AHIDAGRO, a project committed to achieving agricultural sustainability in Macaronesia. AHIDAGRO addresses challenges associated with water stress in plants by developing natural products and solutions that protect crops during water-deficit periods. To date, they have developed new methods for evaluating biostimulants and tested new biostimulants in field conditions. The findings offer a resource for communities struggling with water shortages worldwide.
