The GreeNTD is based on a socio-ecological territorial development methodology that supports a wide stakeholder’s engagement in seeking progressive territorial consensus through a holistic, bottom-up and negotiated vision. The final objective is to get an agreed, socially legitimate and sustainable use and management of natural resources whilst safeguarding the ecosystem, current and future. The proposed methods and tools are thought to facilitate the potential users in the implementation of the approach and to facilitate the application of the agreement. The toolkit presents a set of tools to be used in various steps of the territorial development interventions within the GreeNTD framework, providing practical examples to support their implementation. It is intended to facilitate the implementation of a "learning by doing" process, designed by a progressive adoption of the proposed tools, depending on the context, resources and the level of complexity to deal. The toolkit does not intend to provide narrow steps to be followed as a recipe; it rather proposes a set of various methodological options and examples of tools that can support the process, related to its various key aspects.
