The focus is on Spain, but many of the conclusions areapplicable worldwide. Project splitting is a much more common practice than generallyaccepted. The main efforts have been focused on preventing salami-slicing as a mechanismto avoid the EIA, but it is a much more complex problem, with different ways of splitting andreasons for doing so. Measures to avoid this practice should include strengthening the strategicenvironmental assessment, a greater involvement of the approval authority, specific prohibitionsin regulations, using case-by-case examinations instead of thresholds, compulsory scoping andavoid the exclusion of project parts during the EIA.engjournal article1471-5465https://doi.org/10.1080/14615517.2016.1159425https://www.tandfonline.com/doi/full/10.1080/14615517.2016.1159425#abstractrestricted accessEIAProject splittingSalami-slicingSpainMedio ambiente natural5902.08 Política del Medio Ambiente
