A review of hydro-meteorological hazard, vulnerability, and risk assessment frameworks and indicators in the context of nature-based solutions

Nature-based solutions (NBS) are increasingly being implemented as suitable approaches for reducing vulnerability and risk of social-ecological systems (SES) to hydro-meteorological hazards. Understanding vulnerability and risk of SES is crucial in order to design and implement NBS projects appropriately. A systematic literature review was carried out to examine the suitability of, or gaps in, existing frameworks for vulnerability and risk assessment of SES to hydro-meteorological hazards. The review confirms that very few frameworks have been developed in the context of NBS. Most of the frameworks have emphasised social systems over ecological systems. Furthermore, they have not explicitly considered the temporal dimension of risk reduction measures. The study proposes an indicator-based vulnerability and risk assessment framework in the context of NBS (VR-NBS) that addresses both the above limitations and considers established NBS principles. The framework aims to allow for a better consideration of the multiple benefits afforded by NBS and which impact all the dimensions of risk. A list of 135 indicators is identified through literature review and surveys in NBS project sites. This list is composed of indicators representing the social sub-system (61% of total indicators) and the ecological sub-system (39% of total indicators). The list will act as a reference indicator library in the context of NBS projects and will be regularly updated as lessons are learnt. While the proposed VR-NBS framework is developed considering hydro-meteorological hazards and NBS, it can be adapted for other natural hazards and different types of risk reduction measures

Disaster Risk Management and Spatial Planning: Evidence from the Fire-Stricken Area of Mati, Greece

The debate over spatial planning highlights the need for more interdisciplinary, strategic, and collaborative methods to achieve broad policy goals such as resilience and sustainability. Risk-based planning is gaining importance due to the rising vulnerability of urban infrastructure. Incorporating disaster risk management into spatial planning requires a geographically based strategy for reducing catastrophe risk. This article outlines the role of spatial planning in the reconstruction of the Mati settlement in Attica, Greece, that was devastated by a forest fire in 2018. It presents a set of proposals that relate to the urban reorganization of the area and considers disaster risk reduction and disaster management, as well as sustainability issues relating to mobility, the management of the natural environment, and the recovery of the coastline as a public resource. The basis for this article is the contribution of the Urban Planning Research Laboratory of the National Technical University of Athens/School of Architecture to the preparation of the Special Urban Plan for the fire-stricken area of Mati, Attica, on behalf of the Technical Chamber of Greece
