One of the most popular terms in conservation these days is “nature-based solutions” (NbS). The concept is centered around the various ways in which conservation (including restoration and sustainable use) can benefit society, economy and environment. NbS are alternatives to engineered solutions to these problems, which benefit people as well as nature. Sounds straightforward, and the concept has been taken up in government policy and largely embraced by conservation science. And yet it has been somewhat divisive, for very different reasons.

Joy Ommer is scientific lead at KAJO, a Slovakia-based geoservices consultancy focused on disaster risk reduction and management. In a recent paper she and some project partners write about the importance of understanding the impacts of nature-based solutions before they are actually implemented. We discussed this and other issues around the NbS concept.
