# Blog: first-mile traceability, EUDR and farmer data > The Farmer1st blog explains the first mile: regulation such as EUDR and CSDDD in plain language, practical guides on polygons, due diligence and field data, commodity and origin insights, and our view on farmer-controlled data, pre-competitive collaboration and measurable impact. Articles cite official sources where they state facts.
