“…The proposed installation cost sums up to 70.5 million €, with annual maintenance costs of 1.97 million €. In comparison, the damage in Metropolitan Lisbon during the 2000-2011 floods was assessed to 10 billion €, corresponding to about 400 million € for an area similar in size to ours (Leal et al, 2020).…”

Abstract. This study assesses the potential benefit of Blue-Green Solutions (BGS), green rooftops, rain gardens, permeable pavements, and bioswales, in Lisbon, Portugal. These proposed mitigation measures are applied using TFM-DYN (Nilsson et al., 2021) to simulate potential fluvial flooding distributions from a 10- and 50-year rain event.Water depth of over 30 centimeters can cause damage to infrastructure. The model results show water depths of over 40 centimeters in some parts of the study area for the 10-year return period, raising the need for action. For the 50-year return period even more areas will be affected. These floods can occur at a relatively rapid pace. Four BGS were implemented for flood mitigation. Areas with green roofs and rain gardens showed a lowering in water depth for both return periods. This study shows that even relatively simple data allows for an estimation of urban flooding and the potential effect of BGS for specific locations can easily be determined.

“…Even though the human damage from the flood has been reduced. In recent years, material losses have increased due to the growing importance of urban flooding driven by expansion of watertight areas (Leal et al, 2020). Slovenia has a long history of flooding, and flash floods, major floods and karst floods are frequent annual occurrences (Mikoš, 2020).…”

Human activities have caused changes in land use, climate, and rainfall in the last few centuries, one of which is marked by an increase in the occurrence of floods. Flood events in Europe in the period 1998 – 2009 caused more than 1100 damage and displacement of more than one million people. To overcome this, the European Commission (EC) published the Flood Directive 2007/60/EC (FD) with the aim of reducing and managing flood risks for human health, the environment, natural resources, and economic activities. This paper aims to determine the policies and management of the government and the community towards flood disaster management in the future from the results of research conducted in countries in Europe (Portugal, Slovenia, Serbia, and Bosnia & Herzegovina) and then a comparison is made with conditions in Europe. Indonesia to see the differences and similarities in the perception of the government and the public regarding policies and management of flood events that occur in Indonesia. The provision of infrastructure requires not only technical and financial capacity but also appropriate coordination between different government agencies. Disaster risk reduction through appropriate land use planning and control is an important instrument for securing urban areas from flooding (as a result of a case study in Indonesia). Perceptions of future flood management and control policies require serious attention from various lines, especially within the government as policy makers and the community as implementers in the field.

“…In the first FRMPs developed by EU Member States, a number of measures to mitigate floods were considered, with ~50% relating to prevention and preparedness, ~40% to protection against flood and ~10% to recovery (Leal et al, 2020). The FRMP for Portugal included several structural measures for flood prevention and protection, such as dredging, regularization, and requalification of watercourses.…”

“…Between 2005 and 2014, fluvial floods alone led to annual average losses of EUR 115.8 million (Santos, 2015). Although human damage from floods has been decreasing in recent years, material losses are increasing due to the increasing importance of urban flooding driven by the expansion of impervious areas (Leal et al, 2020). Nevertheless, only 6% of flood‐prone areas are located in the urban fabric, placing Portugal as the second lowest EU country in terms of artificial surfaces under threat from flood hazard (Lugeri et al, 2006).…”

“…In the FRMPs for Portugal and Slovenia, private flood insurance is non‐mandatory, included in private property insurance. Insurance can be considered a risk transfer tool, where policyholders assign the risk of financial losses arising from floods to insurance companies, in exchange for payment of fixed annual amounts (Leal et al, 2020).…”

Flood legislation and land policy framework of EU and non‐EU countries in Southern Europe

et al. 2021

Floods are a widespread natural hazard affecting people and their assets in regions worldwide, including Southern Europe. Besides coastal floods, the Mediterranean region is highly prone to flash floods driven by short but intense precipitation events. With increasing flood risk due to climate change and socio‐economic conditions, governments are under pressure to reinforce flood protection measures, which could be a great challenge for the weak economies of non‐EU developing countries. This is of particular relevance to achieving international commitments such as the United Nations Sustainable Development Goals. Several policy frameworks have been developed to mitigate flooding risk, at European Union (EU) and global level. These frameworks call for a holistic risk reduction approach where governments, institutions, and households are all responsible for reducing risk. In practice, however, gray infrastructure remains the prevailing flood risk management measure in many countries. Incorporation into national legislation and implementation of the EU policy framework will increase constraints and pressures for non‐EU countries, particularly those strongly committed to becoming EU members in future. This article provides a comprehensive review of policies and measures implemented in four different southern European countries to mitigate flood hazard, and compares governance aspects between EU (Portugal and Slovenia) and non‐EU countries (B&H and Serbia). Understanding governance aspects and the status of flood‐related policy implementation is of critical importance in protecting people and enhancing resilience to climate change impacts. Programs of improvement measures and further integration of sustainable water management with other sectoral policies are required to reduce flood risks.
