Collaboration and partnerships establish relations across sector boundaries. Amongst others their aim is to enhance the potential for learning, adaptation, and social capital. Collaboration and partnerships can be driven top-down by the public sector, or bottom-up by the private sector or the civil society. The combination of “partners” within a partnership or network is fully variable throughout the sectors and can take different “forms” of organization. Prominent examples for partnerships and networks for the provision of agri-environmental public goods are collective action and collaborative partnerships, communities of practice and the LEADER approach.
