Press Release: 12-step technical guidance document integrates NbS into project development

The IDB, in collaboration with Acclimatise, are launching a 12-step technical guidance document to integrate NbS into project development.

A fresh-off-the-press IDB technical guidance document will help LAC-based project developers prepare bankable Nature-based Solutions (NbS) projects that provide a substitute, compliment or safeguard to conventional ‘gray’ infrastructure projects.

Nature based Solutions (NbS) can play a central role in meeting the rising demand for infrastructure, and strengthening the resilience of infrastructure assets. They offer a cost-effective approach to enhance resilience, while providing a range of social and environmental benefits (e.g. recreational opportunities, habitat for biodiversity). In this context, NbS refer to activities associated with the protection, management, enhancement, and restoration of nature and implemented to deliver climate resilient infrastructure. This could refer to re-forestation activities for erosion control, coral reef restoration for coastal protection, and green space creation for stormwater runoff control in densely populated urban areas.

There is a high awareness of the benefits and services that NbS can provide, yet significantly less implementation within the Latin American and Caribbean (LAC) context. Their potential remains largely untapped due to a number of barriers that prevent mainstreaming NbS into project development. Some of these barriers are upstream, for example, the lack of NbS incorporation into infrastructure policy and planning documents, or a lack of financial instruments to finance NbS. Other barriers are further downstream: these include, the challenges of defining the business case and accessing finance and funding, and the lack of adequate data, methods, and tools to incorporate NbS into project development.

In tackling some of these downstream challenges, the IDB, in collaboration with Acclimatise, have released a 12-step technical guidance document to integrate NbS into project development. The Guidance is targeted to planners, engineers, architects, contractors and operators interested in preparing bankable climate resilient projects that incorporate NbS either as a substitute, complement or safeguard to conventional infrastructure projects.

How was the guidance developed?

In September 2019, the IDB convened a workshop with a range of LAC-based project developers and international experts with experience in NbS implementation (e.g. Deltares, World Bank, World Resources Institute, U.S. Army Corps of Engineers). As LAC as a whole is early stages of NbS implementation, the IDB considered it opportune to leverage lessons learned from other parts of the world where NbS is more mainstream in project development, for example the Netherlands. At the workshop, the NbS experts iterated a preliminary technical guidance document that was drafted based on a review of LAC and international literature. The experts iterated the early stage draft and helped answer important questions such as ‘is this how it works in practice?’ ‘what steps or processes still need to be incorporated in this document?’, ‘what are the important LAC-specific elements that must be included?’.

The NbS experts shared their experiences and insights which were incorporated in the document, both at the workshop and throughout an extensive review in the months after.  The end product is the result of a participatory process incorporating multiple iterations with field experts, and should be considered a reference (or “go-to”) document for project developers interested in developing NbS projects in LAC, and globally.
