NbS Triple Win Toolkit: Principles 16 Of major value to any NbS project are factors which ensure sustained benefits beyond the project implementation period. Building local capacity, for example by providing training on implementation, monitoring or the development of sustainable business plans, can enable long-term participation and build ownership. Additionally, developing local or private sector partnerships and aligning with national policy frameworks can provide legitimacy, the potential to influence policies, and the long-term capacity to implement solutions and replicate best practices7,14,20. This mainstreaming lays the foundation for project legacy and generating public benefits beyond the project outcomes as policy supports the broader application of NbS across landscapes and time scales10,21,22,23. Connecting to the private sector through sustainable financial markets and models also ensures Design with longevity and futureproofing in mind that benefits from alternative livelihoods or connections to markets extend into the future and are not reliant upon temporary subsidies, project grants or donor interests14 (See Economics and Finance). By both building local capacity and mainstreaming at nationallevels, principles of NbS are embedded across sectors andpolicy frameworks which provides longevity and futureproofing against shifting political priorities.
