Abstract. Hydro-meteorological risks due to natural hazards such as severe floods, storm surges, landslides and droughts are causing impacts on different sectors of society. Such risks are expected to become worse given projected changes in climate, degradation of ecosystems, population growth and urbanisation. In this respect, nature-based solutions (NBSs) have emerged
as effective means to respond to such challenges. A NBS is a term used for
innovative solutions that are based on natural processes and ecosystems to
solve different types of societal and environmental challenges. The present
paper provides a critical review of the literature concerning NBSs for
hydro-meteorological risk reduction and identifies current knowledge gaps
and future research prospects. There has been a considerable growth of
scientific publications on this topic, with a more significant rise taking
place from 2007 onwards. Hence, the review process presented in this paper
starts by sourcing 1608 articles from Scopus and 1431 articles from the Web of
Science. The full analysis was performed on 146 articles. The analysis
confirmed that numerous advancements in the area of NBSs have been achieved
to date. These solutions have already proven to be valuable in providing
sustainable, cost-effective, multi-purpose and flexible means for
hydro-meteorological risk reduction. However, there are still many areas
where further research and demonstration are needed in order to promote
their upscaling and replication and to make them become mainstream
solutions.
