GeoAI in Integrated Hydrological and Fluvial Systems Modeling
Geospatial artificial intelligence (GeoAI) allows the harnessing of big and high-dimensional data to better understand the hydrological processes in a particular system. Specifically, GeoAI provides new data analytic tools to the entire data processing cycle, such as sensor data fusion, hydrological modeling, data assimilation, multi-objective scenario optimization, smart decision support, evaluation of climate change impact, construction of early warning systems, and geo-visualization.

Gaseous Emissions from the Composting Process
Compost can be used in agricultural activities due to its various positive impacts on the physical and chemical properties of the soil, meanwhile reducing utilization of inorganic fertilizers. Composting has also negative environmental impacts, some of them of social concern. This is the case of composting atmospheric emissions, especially in the case of greenhouse gases (GHG) and certain families of volatile organic compounds (VOC).

Framework Proposal for Achieving Smart and Sustainable Societies
The proposed model is based on the integration of three smart strategies: (1) water provision that consists of the use of greywater and rainwater; (2) sanitation provision that comprises the nutrients recovery from excreta and organic solid waste and; (3) resource-oriented agriculture that conceives the use of the water provision system for the production of food with the use of nutrients recovered from the sanitation system. The S3 framework has the potential to increase the well-being, human development, water availability, food safety, poverty alleviation, and healthy environments of societies through the provision of safely managed basic services as well as the recycling of nutrients and water to achieve sustainability at household and community levels.

Fire Tracking Based on Satellite Videos
Fire tracking has become an attractive application of satellite remote sensing thanks to the characteristics of recent remote sensing images, such as high frequency, large range, and multi-spectrum. Additionally, the high-resolution images provide more information and high-time resolution data in forest fire monitoring, showing great potential in environment monitoring. In recent years, many researchers have concentrated on the activate fire detection based on single images, while a few pieces of literature tracked the fire and smoke based on multi-temporal detection or continuous detection. A vital component of fire tracking from remote sensors is the accurate estimation of the background temperature of an area in a fire’s absence, which helps identify and report fire activity.

Fibrous Plant-Based Food Waste for Sorbing Heavy Metals
“Heavy metals” are associated with environmental pollution, food contamination, and toxicity and have adverse effects on terrestrial and aquatic ecosystems and animal and human health. Hazardous heavy metals and metalloids, such as arsenic (As), cadmium (Cd), chromium (Cr), lead (Pb), and mercury (Hg), and several essential heavy metals, such as copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), and zinc (Zn), above threshold levels, have been identified as priority contaminants and one of the key environmental issues of global concern due to their mobility in terrestrial and natural aquatic ecosystems and their carcinogenic nature. Use of inexpensive and abundantly available biosorbents generated from fibrous plant-based food-waste materials to remove heavy metals has garnered considerable research attention.

Fibre Composite Manufacturing Technologies in Shipyards Industry
Fibre-reinforced polymers (FRPs) are one of the most attractive materials for engineering application. In recent times, fibrous composites have become a strong alternative to steel in the construction industry. The general advantages of FRP compared to conventional materials include high durability, cost-effective fabrication, excellent resistance to corrosion, fatigue, and fire, lighter weight, and lower maintenance costs. Owing to their unique properties, FRP composites can be successfully used in the automobile, aerospace, and marine industry, especially for lightweight constructions.

Feasibility of a 100% Global Renewable Energy System
Controversy exists as to whether renewable energy (RE) can provide for all the world’s energy needs. It is found that the energy that could be delivered by these two sources is much less than often assumed, for several reasons: The declining quality of inputs; the need for inclusion of uncounted environmental costs; the need for energy conversion and storage; and the removal of existing fossil fuel energy subsidies.

Exposure Effects Related to Nanomaterial Life Cycles
Nanoparticle-based biosensors are produced and utilized at different scales ranging from laboratory to industrial domains. While incorporating nanomaterials is beneficial to developing high-performance biosensors, at the stages of scale-up and disposal, it may lead to the unmanaged release of toxic nanomaterials. When considering the potential environmental impact and health safety of the scaled-up production of nano biosensors, it is necessary to examine the manufacturing, utilization, and end-of-life disposal of the nanomaterials used.

Evolution of Microgrid Technology
Microgrids are energy systems that can operate independently or in conjunction with the main electricity grid. There are numerous subdomains of microgrid technology research, each of which focuses on a distinct component of microgrid design, operation, and management. Energy storage, control, power electronics and power quality, renewable energy integration, stability, storage, protection and cybersecurity, regulation and distribution, and economic and business models are some of the major areas of microgrid technology study.

Evaluating Geothermal Systems through Life Cycle Assessment
In these days of heightened environmental consciousness, many countries are shifting their focus towards renewable energy sources for both large-scale uses (such as power plants that generate electricity) and smaller-scale applications (e.g., building heating and cooling). Taking into account a holistic method, LCA on the one hand allows to display the whole life cycle of a system from the extraction of raw materials, its creation to the production phase and finally to its disposal. On the other hand, it reveals through multiple environmental impact categories, the hot spots that account for the different stages of the cycle defining the environmental identity of the system and consequently driving policy makers on taking final decisions. Geothermal energy is an extremely viable alternative that, combined with other renewable energy systems, may mitigate the negative effects of the existing energy mix worldwide.
