Green roof substrates provide water, nutrients, and physical support to vegetation development, as well as being a key element in the hydrological performance of the system. In this regard, the use of aggregate components that improve physicochemical properties of the substrates optimises the ecosystem services provided by green roofs. This study demonstrates the effects of using rice husk as an aggregate material in engineered substrates for extensive green roofs. Sixteen different substrates compositions were tested with different proportions of natural (NRH) and carbonized (CRH) rice husk incorporated into a base mixture with fixed proportions of vermicompost, vermiculite, and construction waste. The study consists of two phases: i) laboratory analyses to assess the substrates' physicochemical properties, and ii) a pilot-scale field experiment to evaluate hydrological performance under real subtropical climate conditions and vegetation development using a monoculture planting of Sedum rupestre. The findings showed that CRH has the potential to improve some physicochemical properties, such as water holding capacity, bulk density, and porosity. Additionally, CRH substrates presented a slightly increased average retention rate (up to 7%) comparing to local topsoil. The average stormwater retention rate for all engineered substrates was 77.73%. Multiple linear regression models were satisfactorily fitted to observed data from the open field experiment allowing an estimation of potential substrates’ retention rates. Moreover, vegetation development was positively affected by adding CRH comparing to the NRH. Carbonized rice husk presents as a useful material for improving green roof substrates properties and could be a sustainable alternative for local agriculture waste management.

Green roofs and green walls are a potential strategy to increase green spaces in the urban environment. These solutions bring multiple benefits to the cities at the economic and socio-environmental levels. However, from the point of view of private investors, green roofs and green walls often have a negative financial evaluation. Concerning this, the quantification of the benefits according to building use and occupancy could be an important tool to assist the decision-making process and guarantee returns on investment. This study aims to support the decision-making process by managers and owners of youth hostels regarding green roofs and green walls implementation. Using a structured questionnaire, users’ perceptions were assessed through a five-point Likert scale. The survey was conducted in five youth hostels in Lisbon, Portugal. Analyses were performed in two phases. Firstly, using the original sample (n = 345), and subsequently grouping homogeneous individuals through cluster analysis. The results showed that most respondents support green infrastructure installation in the hostel and consider that these solutions could provide a greater sense of individual well-being and local aesthetic improvement. However, there is no strong evidence that green infrastructure solutions are considered a deciding factor to select local lodging, despite the fact that it can be a tiebreaker factor between two similar options. Furthermore, findings have shown that 90% of the respondents from Cluster 1 and 92% from Cluster 4 are probably not willing to pay higher daily rates for youth hostels that have green infrastructure solutions in place. On the other hand, 67% of the respondents from Cluster 2 were potentially willing to pay an additional amount. For the 345 respondents, the most preferred green infrastructure typologies are indoor living wall and the accessible green roof. Moreover, findings support the gender socialization and identity theory showing that women have a greater environmental concern compared to men.

Worldwide, green infrastructure is increasingly used to mitigate the impacts of dense urban areas, contributing towards the naturalization of the built environment. However, for investors, these systems often emerge as requiring substantial upfront cost (high installation costs) and, depending on the solution, might also have significant maintenance costs. On the other hand, policymakers are placing green infrastructure on the agenda, as a solution to consider in urban planning and design. There is a mismatch between the economic/social/environmental value of green infrastructure and their financial analysis. As the quantified benefits of these solutions may not compensate the high implementation costs, discouraging building owners to invest in them. The alignment of both expectations, public and private agents, regarding the development of green infrastructure, is done through the use of incentives, with distinct configurations and nature, that promote and facilitate the adoption of green infrastructure by private investors. This research aims to identify and analyse the incentive policies used by several municipalities to promote the installation of green roofs and/or green walls. The data set includes 113 cities in 19 countries. The incentive policies were classified into six different categories: tax reductions, financing, construction permit, sustainability certification, obligations by law and agile administrative process. The results show that incentive policies are mainly concentrated in Europe and North America, and most incentive policies focus on the promotion of green roofs, as no exclusive incentive policies for the promotion of green walls were found. From all incentive policies studied, financial subsidies and obligations by law are the most used ways to promote green infrastructure worldwide.

A análise ambiental de nascentes pode ser entendida como um método para a verificação da qualidade do ambiente no seu entorno, e possíveis impactos na qualidade das águas e na sua viabilidade para consumo humano. O presente estudo objetivou analisar nove nascentes na zona rural do município de Cunha Porã/SC, utilizadas para abastecimento humano. Para tanto, foi realizada avaliação ambiental macroscópica e foram analisados parâmetros físico-químicos e microbiológicos da qualidade da água: pH, nitrogênio total, fósforo total, oxigênio dissolvido, 2,4 – D, Glifosato, Atrazina, turbidez, temperatura, condutividade elétrica, coliformes totais e Escherichia coli. Foi verificado o não cumprimento da legislação vigente no que tange as Áreas de Preservação Permanente e possíveis impactos ambientais associados. Com relação à qualidade, as águas das nascentes se apresentaram como não potáveis, devido à presença de 2,4-D e Atrazina acima dos limites para potabilidade, bem como a positividade de Escherichia coli em 100% das amostras. Sendo assim, há potencial risco à saúde da população que faz uso da água dessas nascentes.

A substituição de coberturas impermeáveis por coberturas verdes têm apresentado-se como uma alternativa ambientalmente adequada para a redução do escoamento superficial das águas da chuva. Nesse sentido, essa pesquisa avaliou a eficiência da composição do substrato de telhados verdes na redução do escoamento pluvial. Para tanto, foi realizado o monitoramento de eventos de chuva e vazão, considerando 40 sistemas experimentais (10 tratamentos, com 4 repetições em cada) de telhados verdes modulares, compostos por solo puro, substrato comercial puro e pela combinação de diferentes substratos: casca de arroz carbonizada, casca de arroz in natura e solo. Não houve diferença estatisticamente significativa na taxa de retenção média entre os tratamentos avaliados. Apesar disso, verificou-se que todos os tratamentos testados apresentaram taxa média de retenção do escoamento pluvial igual a 74%, o que demonstra o potencial de utilização de resíduos como a casca de arroz na composição de substratos para telhados verdes, visto seu custo ser mais baixo que o custo de substratos comerciais, devido às suas propriedades como leveza, porosidade e boa drenagem, além de constituir-se em uma alternativa ambientalmente adequada para a destinação desse passivo ambiental.
