<p>There is growing recognition that using the properties of nature can help provide viable and cost-effective solutions to a wide range of societal challenges, including disaster risk reduction. However, nature-based solution (NBS) realization depends critically on the legal, institutional, social, political and financial conditions – that is, the governance framework - that enable the NBS policy process. Drawing from three case studies in Nocera Inferiore (Italy), Munich (Germany) and Wolong (China), we identify key governance enablers of successful NBS - that is, the contextual pre-conditions, policy processes and institutions that proved helpful or even essential for the initiation, planning, design and implementation of NBS. Results show that the most critical enablers involved governance innovation in three areas: polycentric governance (novel arrangements in the public administration that involved multiple institutional scales and/or sectors), NBS co-design (innovative stakeholder participatory processes that influenced the final NBS) and financial incentives (financial incentives for community-based implementation and monitoring of NBS). Further enablers for realizing NBS, as demonstrated in the three cases, include environmental advocacy coalition groups, along with their individual champions, and a major triggering or modelled event, which opened a window of opportunity to advocate for a nature-based or hybrid green-blue-grey solution. Findings show that the transition from grey solutions to NBS can be justified with, and contribute to, multiple global agendas and targets, including disaster risk reduction, climate change adaptation, halting biodiversity loss and sustainable development.</p>

This study presents an analysis of risk and resilience perceptions in two villages of Far West Nepal, Sunkuda and Bajedi, located in the upper Karnali River Basin. The area has been affected by deep-seated and shallow landslides, which have had a devastating impact on many rural lives and livelihoods. While both villages are exposed to landslides, Bajedi is situated in a higher risk zone. Using structured surveys, semi-structured interviews and insights from stakeholder workshops, the risk and resilience perceptions of household residents of the two villages are elicited. The objectives of the study are 1) to understand how residents perceive their risk and resilience to landslides, and 2) to provide evidence and insights on the factors that influence risk perception. Results show that landslides are perceived as an existential risk in both villages, although risks are perceived as more serious in Bajedi. The higher risk perception in Bajedi is shown to be mainly driven by households' ability to cope, including their energy sources, whether they know whom to call in case of a landslides, as well as household savings and income sources. In Sunkuda, risk perception is shown to be influenced by households' access to and status of community forests, expenditure on medication, the seasonality and types of water sources, and ethnicity. In both villages, additional drivers of risk perception include households' social networks, their perceived triggers of landslides, their outstanding loans, and who collects the water. The results demonstrate the interconnectedness of risk perception and indicators of resilience. By elucidating the risk perception of Sunkuda and Bajedi, this study has important implications for local risk management strategies and policies.

Abstract. - Natural hazards are an acute topic for land-use planning in the region Provence-Côte d'Azur. Two damaging events are studied : earthquakes and their secondary effects like rockfalls and landslides, floods in the urbanized valleys.
