The University of Minho, in collaboration with Sogrape Vinhos , is studying the beneficial effect of 17 species of native plants sown between the alley rows of a Douro vineyard.

Several studies indicate a sharp decline in biodiversity, accelerated by climate change. The Interreg Sudoe project “Fleurs locales” integrates 7 institutions in Portugal, Spain and France with the aim of promoting alternatives to the massive erosion curve of biodiversity in agrosystems, using plant covers of native species.
