Coastal areas are often subject to the severe consequences of flooding from intense storms or hurricanes. Increases in coastal development have amplified both flooding intensity and negative impacts for coastal communities. Reductions in pervious land cover and replacement with impervious ones have reduced the amount of ecosystem services. This research examines the services provided by nature-based solutions by applying outputs from Co$ting Nature models into suitability models to quantify ecosystem services along the Texas Coast. Results show that only around 13% of the Houston-Galveston coastal area has relatively high NBS, and nearly ¼ of the area shows relatively low NBS. The majority of the areas lie in the middle, which, due to increases in development, are at particular risk for becoming areas offering low NBS in the future if not treated. Such vulnerability assessment informs future implementation strategies for NBS in coastal communities to protect people and property from flooding.

The aim of the article is to assess the present level of land development of flood risk areas in selected communes of the Łódź province in the context of potential negative consequences for people, the natural environment, cultural heritage and economic operations. The research includes urban as well as urban and rural communes (9 communes in total) of the Łódź province which display high and very high flood risk levels according to the methodology used in Flood protection operating plan for the Łódź province from 2013 ( Plan operacyjny… 2013). Uniejów and Warta have the highest synthetic flood risk levels due to the surface occupied by buildings and areas assigned to individual risk categories. In turn, Łowicz and Tomaszów Mazowiecki (town) display the highest general flood risk level due to diversification of buildings and areas of individual risk categories.

Abstract. Private risk reduction behaviours can significantly reduce the negative impacts of flooding and flash floods. Over the past decades, researchers have used various socio-cognitive models or threat/coping mechanisms to explain individual protective behaviours. However, these models ignore that people are not equally ready to act upon a danger and they give limited insights into the effectiveness of communication strategies to foster risk reduction behaviours. Therefore, we explored the current state of homeowner's readiness to undertake risk reduction behaviours in flood risk areas by applying a dynamic protection motivation framework. We conducted a survey in an Italian municipality that experienced severe flash flooding in September 2018. The results show that people are motivated by different factors in prompting risk reduction behaviour based on their type of protective measures. For example, people that undertook structural or avoidance measures are more likely to be motivated to protect themselves by increased perceptions of vulnerability and response efficacy, and are less worried about expected flood losses compared to people that undertook only basic emergency measures. In this paper, we argue how these new insights contribute to target flood risk communication strategies to groups of individuals characterized by different readiness stages and motivations to protect themselves.

Accelerated coastal erosion and elevated risks of flooding due to global warming put enormous burden on the ecosystems and economic health of coastal communities. Optimal policies to lessen these negative impacts require an estimation of their costs and benefits. The aim of this paper is to calculate the costs of beach erosion and flood risk through the valuation of property prices in Hilton Head Island, a barrier island located in South Carolina, USA. Spatial lag hedonic pricing was introduced in order to account for spatial autocorrelation in the dataset. The results show that properties that are located within the zone of high, or very high, flood risk experience a 15.6% reduction in value. The implicit price of being located close to an eroded beach is approximately 26% of the price of an oceanfront property. However, this negative impact on property value diminishes with distance from the shoreline.

Abstract The main objective of the study was to identify high flood risk zones in AMA. The study also used questionnaires to assess local knowledge on what accounts for the high flood risk in their community. Spatial analysis techniques were used to model flood risk based on the following contributory factors; land cover, soil, drainage density, topography and proximity to rivers. The results show that high flood risk areas covered 46.3km2(20%), moderate risk area, 72.9km2(31.6%), low risk area 41.5km2(18%) and very low risk areas, about 6.7km2(2.9%). The high flood risk zones were low-lying areas below 50 meters above sea level and closely associated with poor drainage systems. People perceived not just low-lying areas as a paramount reason accounting for flooding but also very bad waste disposal habit of the public. These offsets the efforts of waste management companies to keep drains free of refuse.

Activities carried out in coastal areas such as recreation, fishing activities, and transportation makes coastal regions have an essential role in life. However, activities carried out in the region often leave negative impacts, such as dumping trash directly into the sea. Coastal communities still carry out their activities to dispose of their waste now to the sea. The process of cleaning up marine litter in the coastal areas using heavy equipment is quite tricky. This is because the condition of buildings in the coastal area has the building with the concept of houses on stilts. The research has succeeded in making a marine garbage dredging using a conveyor system that is contained using a wireless joystick and can be well controlled within a radius of about 7 meters. The dredging is also equipped with a weight sensor (load cell) used to determine the load of garbage displayed on the 16 x 2 LCD. Garbage weight is stored in the SD card. The data stored on the SD card will show the time and load of garbage that has been transported by conveyor in an area.

A ocorrência de inundações em áreas urbanas tem se intensificado nos últimos anos, ocasionando diversos danos e prejuízos para a sociedade. O intenso crescimento das cidades nas últimas décadas, assim como a ocupação irregular do espaço urbano com moradias precárias e próximas aos rios, são fatores determinantes para que ocorram essas situações de catástrofes. O objetivo deste trabalho é mapear e identificar as áreas de inundação em setembro de 2011 no município de Itajaí para a confecção do mapa de risco. Para isso foi realizado uma análise histórica do crescimento da malha urbana de Itajaí, correlacionando com as manchas de inundação. Os resultados obtidos revelaram que a inundação ocorrida em 2011 atingiu parte significativa da área do município, com destaque ao perímetro urbano. Os pontos mais críticos de inundação foram às áreas onde houve o crescimento urbano, com destaque as proximidades do rio Itajaí-Mirim. Foi possível analisar por meio do mapa de risco, que grande parte da cidade de Itajaí foi classificada com um alto índice de risco a inundação. Deste modo, pode-se concluir que o mapeamento das áreas de risco configura-se como uma importante ferramenta e instrumento no controle e prevenção à inundação em áreas afetadas por esse fenômeno.   A B S T R A C T The occurrence of floods in urban areas has intensified in the recent years, causing many kinds od damage and loss for society. The intense growth of the cities in the past few decades, along with the irregular occupation of urban space with precarious settlements close to the rivers, were determining factors for these catastrophic situations to occur. The objective of this study is mapping and identifying the flooding areas in September 2011 in the city of Itajaí for the confection of a risk map. For this a historical analysis of the growth of the Itajaí urban area was realized, correlating with the flood spots. The obtained results reveal that the 2011 floods affected a significant portion of the city’s area, especially the urban perimeter. The most critical flood spots were in the areas where urban growth took place, especially nearby the Itajaí-Mirim river. By analizing the map, it’s noted that a big part of the city of Itajaí is classified as a high flood risk area. It can be concluded that the mapping of risk areas is an important tool and instrument in the control and prevention of floods in the areas affected by this phenomenon.

Coastal villages have different characteristics from villages in rural areas. This difference is not only on the geographical-ecological aspect, but also on economic and socio-cultural characteristics. Geographically, coastal villages are on the border between land and sea. Geographical-ecological conditions of coastal villages affect economic activities in them. Economic activities in coastal villages are characterized by activities in the utilization of coastal environmental resources and services. Economic activities include fisheries, trade, maritime tourism, and transportation This study seeks to study the application of tough coastal development programs as an effort to build an oriented coastal region to facilitate the economic activities of villages in coastal areas that are expected to reduce the poverty rate of coastal communities in the middle of the city. This study uses a qualitative research design using descriptive methods that intend to explain how the phenomenon of resilient coastal village development and coastal area development as an effort to reduce the number of coastal communities in Central Java province by using purposive sampling sampling techniques and research samples taken in coastal communities The results of the north coast of Java  and cilacap districts were as follows: that the implementation of the strong Coastal Village Development Program in the coastal communities of Central Java showed that the three focuses of development activities had been carried out properly. The development activities are resource development, environmental / infrastructure development, and disaster preparedness development. While activities that are not carried out are human development and business development. The recommendations given in this study are that the implementation of the program must be supported by sufficient funds, need coordination and cooperation with other stakeholders, and the need for effective monitoring and evaluation Keywords: program implementation, coastal village, coastal area development, Poverty, Central Java

Abstract Coastal ecosystems are linked to socio-economic development, but simultaneously, are particularly vulnerable to anthropogenic climate change and sea level rise (SLR). Within this scope, detailed topographic data resources of Spercheios River and Maliakos Gulf coastal area in Greece, combined with information concerning the economic value of the most important sectors of the area (wetland services, land property, infrastructure, income) were employed, so as to examine the impacts of three SLR scenarios, compiled based on the most recent regional projections reviewed. Based on the results, in the case of 0.3 m, 0.6 m and 1.0 m SLR, the terrestrial zone to be lost was estimated to be 6.2 km2, 18.9 km2 and 31.1 km2, respectively. For each scenario examined, wetlands comprise 68%, 41% and 39% of the total area lost, respectively, reflecting their sensitivity to even small SLR. The total economic impact of SLR was estimated to be 75.4 × 106 €, 161.7 × 106 € and 510.7 × 106 € for each scenario, respectively (3.5%, 7.5% and 23.7% of the gross domestic product of the area), 19%, 17% and 8% of which can be attributed to wetland loss. The consequences of SLR to the ecosystem services provided are indisputable, while adaptation and mitigation planning is required.
