About Yolanda Rovira
In the dusty trenches of medieval Córdoba’s Alcázar gardens, Yolanda Rovira identified charred grape pips with microscopic starch signatures that proved Islamic agronomists were cultivating heat-tolerant Vitis vinifera cultivars centuries before European viticulture texts acknowledged them, a finding that rewrote assumptions about crop adaptation under climate stress. Her lab doesn’t just ID seeds; it cross-references phytolith morphology with Arabic irrigation treatises and pollen stratigraphy from Sierra Nevada lake sediments to map how Andalusian farmers rotated drought-resistant millets with nitrogen-fixing legumes during the 10th-century megadrought. She carries a hand-carved olive-wood sieve inherited from her abuela, not as nostalgia, but because its mesh size matches the precise aperture needed to recover 0.3mm chaff fragments from Visigothic granaries. Her work insists that plant remains aren’t passive data points, but palimpsests of decision-making: every carbonized barley grain is a record of harvest timing, storage choice, and ritual offering.
