NATURE-BASED SOLUTION AS FLOOD PROTECTION STRATEGIES: THE CASE OF CARAHÁ RIVER PARK, BRAZIL
Following the road paradigm, many cities, at the beginning of the 20th century, experienced a reckless increase in the number of vehicles on the road causing an unsustainable urban and environmental situation. The origin of the problem surely lies in the occupation of the preserved areas. In many South American states, for example, highways generally ignore the presence of environmental obstacles (such as rivers) as they may cause a “delay in modernization”. As a result, riparian forests are invaded and turned into highways, water beds are channeled and most rivers are contaminated with wastewater. Due to the occupation of green and riparian areas, urban floods have become more and more and consequently urban spaces have been disqualified. This situation also involved the Carahá River that crosses the city of Lages in southern Brazil, in fact the river embankment has become completely impermeable due to the construction of an urban road. Proposing urban spaces with an emphasis on improving environmental quality and integrating forms of public transport are basic points that could lead to the sustainable development of our cities. In this context, the aim of this research is to propose a sustainable river project for the Carahá River, with the aim of presenting nature-based solutions to prevent floods and improve the environmental, functional and aesthetic quality of the city. To develop this research, first theoretical studies were carried out on the relationship between rivers and cities, secondly three international case studies and related literature were analyzed with the aim of deepening the knowledge of the connection between rivers and population. Finally, an intensive study of the territory was carried out and a social analysis was conducted through a semi-structured interview in which the population of Lages participated. The result of this study contributed to effectively defining the intervention guidelines for the Carahá river park project considering, as an added value, also the
main needs of citizens

Living Lab Experience in Turin: Lifestyles and Exposure to Black Carbon
State-of-the-art, continuous personal monitoring is a reference point for assessing exposure
to air pollution. European air-quality standards for particulate matter (PM) use mass concentration of
PM (PM with aerodynamic diameters ≤ 10 µm (PM10) or ≤2.5 µm (PM2.5)) as the metric. It would
be desirable to determine whether black carbon (BC) can be used as a better, newer indicator than
PM10 and PM2.5. This article discusses the preliminary results of one of the three living laboratories
developed in the project “Combination of traditional air quality indicators with an additional traffic
proxy: Black Carbon (BC)”. The Living Lab#1 (LL#1) involved 15 users in the city of Turin, Italy.
Three portable aethalometers (AE51) were used to detect personal equivalent black carbon (eBC)
concentrations in the respiratory area of volunteers at 10-s intervals as they went about their normal
daily activities. The Geo-Tracker App and a longitudinal temporal activity diary were used to track
users’ movements. The sampling campaign was performed in November for one week. and each user
was investigated for 24 h. A total of 8640 eBC measurements were obtained with an average daily
personal exposure of 3.1 µg/m3
(±SD 1.3). The change in movement patterns and the variability
of microenvironments were decisive determinants of exposure. Preliminary results highlight the
potential utility of Living Labs to promote innovative approaches to design an urban-scale air-quality
management plan which also includes BC as a new indicator
