Spain's Huelva region has seen a significant increase in blueberry cultivation since the 1990s, now covering over 4,000 hectares. The industry's growth is limited by the specific climatic and soil conditions required for blueberry farming. However, advancements in new variety development and innovative cultivation techniques have enabled expansion into less favorable areas. Despite challenges such as global competition, the sector continues to innovate and efficiently manage water resources. Huelva remains the primary production region, but other areas like Galicia, Asturias, and Extremadura also contribute to Spain's growth as a major European blueberry producer, with a focus on continuous genetic improvement and sustainable practices.
