Portuguese milk producers have demonstrated for a sustainable future of their industry, calling for greater support as the European Union's Common Agricultural Policy (CAP) reform threatens to reduce support. The industry has faced challenges, such as a 30% decrease in effective dairy coils since 2000, despite a 35% increase in yield per dairy cow. The sector is expected to become more competitive and resilient with increasing income levels per dairy cow in the future. However, it also faces consumer shifts towards vegetable drinks, which now account for 20% of the total milk market. Producers are encouraged to adopt environmentally and animal-friendly practices to meet consumer demands and increase transparency about the origin of their food. The author stresses the importance of cooperatives in identifying new solutions and requiring cooperative structures to generate value for a sustainable future in the sector.
