LEAF results from the merging of 4 previous research units from the School of Agriculture, University of Lisbon. Since its creation in 2013, LEAF has been organised in a Cartesian matrix of Research Groups and transversal Thematic Lines. For the period 2018-20, adjustments were made following the Scientific Advisory Committee advice, with a reduction in the number of Research Groups and transversal Thematic Lines. For 2025-29, it has been decided to improve the structural matrix by maintaining the 3 Research Groups and suppressing the Thematic Lines.
