The Azores archipelago is located in the North Atlantic Ocean, including nine volcanic islands. The Azores climate, temperate oceanic, is influenced by the Azores anticyclone, being characterized by high air humidity indices, low thermal amplitude, abundant precipitation and persistent wind. Like other urban areas, Ponta Delgada, in S. Miguel Island, suffers from high impermeabilization with all the negative environmental consequences that arise. As such, the present chapter intends to discuss the opportunity of greening rooftops in urban areas in S. Miguel Island (performing a survey of the roofs and the corresponding area that could be used) showing the advantages that could arise, regarding the environmental performance improvement (e.g., building water storage and heat balance) and their role in the minimization of extreme weather events effects (e.g., urban wastewater infrastructure). As a first step toward evaluating the contribution of these infrastructures in the urban areas of the Azores, a green rooftop pilot study using plants and local substrates has been designed, to be built in the near future.

“…Moreover, the soil water balance method could be used to determine the water needs of individual plant species by measuring the soil moisture content, as shown in Equation ( 81) [84].…”

“…For instance, since GIs (such as trees) could trap heat and reduce wind ventilation, especially at night [38], it is recommended to plant trees with a larger separating distance to enable wind circulation [100]. Further, to address the water consumption challenge, the use of high concentrations of humic acid (200 mg/L) could increase the water use efficiency by approximately 40%; this level of humic acid reduces the evapotranspiration rate by 10-15 mL/day [84]. Since the release of BVOCs and pollen from trees has a significant negative impact on air quality and human health, it is important to further consider species that do not emit BVOCs when designing GIs [101].…”

Models and Methods for Quantifying the Environmental, Economic, and Social Benefits and Challenges of Green Infrastructure: A Critical Review

With growing urbanization and increasing climate change-related concerns, green infrastructures (GIs) are recognized as promising solutions for mitigating various challenges and promoting sustainable development. Despite the important role of GIs, a comprehensive synthesis of the quantification of their full range of benefits and challenges is lacking in the current literature. To address this gap, a systematic literature review was conducted on the quantifiable environmental, economic, and social benefits and challenges of GIs. This paper followed the Preferred Reporting Items for Systematic Review (PRISMA) methodology, where 75 relevant articles were reviewed to present the various models and methods that could be used to quantify and assess the impacts of different GI types. The study further investigated existing knowledge trends and patterns, identified research gaps, and suggested future research directions. The results revealed that while existing research studies offer great insights into the impacts of GIs, a more holistic approach is necessary to balance the benefits and challenges of GIs. The findings also offered a comprehensive understanding of a wide range of environmental, economic, and social considerations of both natural and engineered GIs. Ultimately, the performed literature review serves as a comprehensive guide for researchers and practitioners and could be used in estimating and evaluating the benefits and challenges of GI plans and programs as well as in making informed decisions about GI projects.

“…These changes are highly important for the regulation of water and nutrients in the substrate. Therefore, the substrate stability of physicochemical properties during crop cultivation has important impacts on crop productivity and quality [10,11]. The screening of new microorganisms from the root microbiome of substrate-cultivated crops can provide us with strain resources for the development of fertilizer or mycorrhizal products adapted to new cultivation techniques [12].…”

The use of traditional Chinese medicine (TCM) residue as a crop culture substrate has unique advantages in alleviating the obstacles associated with continuous monocropping, such as increasing production, improving quality and alleviating pests and diseases. However, the effect of TCM residue application on substrates in continuous monocropping practices has not been determined. In this study, the cucumber variety “Jinyou No. 10” was used as the material, and fermented TCM residue, vermiculite and perlite were used as organic substrates (3:1:1). The cucumbers were cultivated on substrates for different durations of continuous monocropping, which were the first cropping cycle (A1), second cropping cycle (A2), third cropping cycle (A3) and fourth cropping cycle (A4). The control (A0) was the substrate sample without any crop planted in it. After the cucumbers were harvested, substrate samples (areas around the cucumber roots) were collected. The physiochemical properties of the cultivated substrates were determined, and the microbial community structures were analyzed through 16S rRNA and ITS sequencing. The physiochemical indices of the substrates with different durations of continuous monocropping (A1–A4) were significantly different than those of the control (A0) substrate. Moreover, the continuous cropping of cucumber had greater effects on fungal communities than on bacterial communities. Bacterial community structure analysis revealed a greater proportion of important bacterial taxa (Proteobacteria, Chloroflexi, and Nitrospirae) in the continuous monocropping substrates than in the A0 substrate. For the fungal community, Ascomycota accounted for the largest percentage of the fungal community in all the samples. The diversity of the microbial community was found to be influenced primarily by electrical conductivity, organic matter content, pH and total potassium content according to the correlation analysis of physicochemical properties and relative abundance of the microbial community. Our study would provide a basis for addressing persistent challenges in continuous cropping and for obtaining the utmost benefit from using TCM organic residue waste.
