Training on “Contracts for the provision of agri-environmental public goods in agriculture – possible implementation solutions in the Mazowieckie Voivodeship” took place on 26/10/2022 in Warsaw. The meeting took 2 hours when we presented good practices and cases of implementations of Contracts for the provision of agri-environmental and climate public goods in agriculture – in Poland (Podkarpacki Wypas, Owca Plus, Kwietne Łąki and selected cases from EU, Ecometan, Humus Program). Practical solutions were discussed for their possible implementation in the programs of Mazovia region. We discussed also what environmental goals can be supported through contracts in Mazovia region. What sources of financing are possible (private/public). We also guided a group how to prepare contract development – step by step. The participants noted the important role of the organizer of such solutions – a public institution or a private entity that could finance such contracts – in case of Mazovia Region It could be Marshall Office or the Agency of Development of Maziovia Region. Private companies could also be interested. We discussed different contract solutions for example “Co2 contracts platform” (reduction of Co2 emissions via practices in farming) or reduction of methane emissions via good practices in cattle production, since Mazovia region is one of leading dairy regions in Poland. Participants concluded that it is important to provide farmers with advice and practical application examples of contracts that could serve as inspiration for taking action to protect public goods.
