NbS Triple Win Toolkit: Principles 14 NbS must be adapted to the unique ecological, socio-economic and political contexts of a project location. Though NbS can be implemented as a suite of interventions, they are not a ‘one size fits all’ approach – just as no two human or ecological systems are exactly alike due to their complex, dynamic interactions. During project design, these interacting factors (i.e. ecological, climate, legal, political, cultural, economic) must be identified within the site and landscape, including those more difficult to monetise or measure13. It is important to consider risks and uncertainties, such as fraud, corruption, natural disaster and climate change, and account for vulnerable groups, political or social conflict, and the stability and availability of financial institutions and markets14. This approach will highlight the trade-offs between different groups and objectives, allowing for issues to be identified and managed from an early stage (see Principles ‘Put in place social and environmental safeguards’ and ‘Consider trade-offs Account for site-specific and complex dynamic contexts and synergies across multiple scales’). A good project design will elevate local values and knowledge alongside scientific evidence, consider the complexity of the ecosystem and interactions with the wider environment, engage a diversity of stakeholders and local communities, and account for institutional capacity or political will to carry out interventions2,10. Therefore, no one NbS will suit all situations and no one intervention will act as a panacea – interventions must be tailored to the landscape- or site-specific contexts.
