Solar Energy Technologies' Sustainable Development towards Solar Photovoltaics
Renewable energy was available in rural areas in the form of wind farms, solar plants, biomass plants and others. In urban contexts, particularly with the use of solar energy technologies called solar energy systems in buildings, such as solar thermal and photovoltaic (PV). The viewpoints on solar energy technologies for sustainable development is  particular to emphasis on photovoltaic (PV), as well as the solar energy technology performance, in order to ascertain worldwide solar energy adoption trends.

Solar Energy Systems into Seawater Desalination
Solar energy, amongst all renewable energies, has attracted inexhaustible attention all over the world as a supplier of sustainable energy. The energy requirement of major seawater desalination processes such as multistage flash (MSF), multi-effect distillation (MED) and reverse osmosis (RO) are fulfilled by burning fossil fuels, which impact the environment significantly due to the emission of greenhouse gases. The integration of solar energy systems into seawater desalination processes is an attractive and alternative solution to fossil fuels.

Solar Desalination
Desalination is a capital-intensive process that requires a significant amount of energy, and since it is now mostly powered by fossil fuels across the globe, it has the potential to leave a significant carbon footprint.

Solar Concentration for Wastewaters Remediation
As the effectiveness of conventional wastewater treatment processes is increasingly challenged by the growth of industrial activities, a demand for low-cost and low-impact treatments is emerging. A possible solution is represented by systems coupling solar concentration technology with advanced oxidation processes (AOP).

Soil, Humipedon, Forest Life and Management
Three sections (Humipedon, Copedon and Lithopedon) were recognized in the soil profile. It was then possible to link the first and most biologically active section to the characteristics of the environment and soil genesis. In particular, it is now possible to distinguish organic horizons, mainly produced by arthropods and enchytraeids in cold and acidic or dry and arid environments, from organo-mineral horizons produced by earthworms in more temperate and mesotrophic environments. Each set of horizons can be associated with a humus system or form, with important implications for forestry. Anecic/endogeic earthworms and Mull or Amphi systems are more abundant in the early and late stages of sylvogenesis; by completely recycling litter, earthworms accelerate the availability of organic and inorganic soil nutrients to roots and pedofauna. On the other hand, arthropods and Moder or Tangel systems characterize the intermediate stages of sylvogenesis, where thickening in the organic horizons and the parallel impoverishment/reduction in the underlying organo-mineral horizons are observed. Recognizing the humus system at the right spatial and temporal scale is crucial for the biological management of a forest.

Soil Washing
Soil contamination with heavy metals and organic pollutants poses an environmental problem due to their persistence, bioaccumulation and toxicity. Soil washing is one of the most common remediation technologies for permanent removal of undesirable pollutants. The effectiveness of soil washing is affected by many factors such as soil geochemistry, pollutant characteristics, type and chemistry of washing agents, and processing conditions. A variety of washing agents have been tested in soil washing with their different effect on pollutant removal and on the overall quality of treated soil. Development of soil washing is based on searching for an inexpensive, readily-available and environmentally-friendly agents to remediate polluted soils. Despite the unquestionable effectiveness of soil washing, spent washing solutions are generated that need further treatment. This entry presents the principles and application of soil washing technology, as well as the examples of washing agents and methods for liquid waste treatment.  Soil washing is an ex-situ technology, including physical and/or chemical processes that aim to effectively remove pollutants from soil.

Soil Remediation Strategy
Although soil is a valuable and non-renewable ecological system, it has always been subject to widespread degradation due to anthropic activities. The most severe risks are point source and diffuse soil pollution. The remediation of contaminated soils and sites is, therefore, a significant step in the protection of the environment and living organisms, and must be included in the broader multidisciplinary scenario of strategic green transition.

Soil Protection in Floodplains
Soils in floodplains and riparian zones provide important ecosystem functions and services. These ecosystems belong to the most threatened ecosystems worldwide. Therefore, the management of floodplains has changed from river control to the restoration of rivers and floodplains. However, restoration activities can also negatively impact soils in these areas. Thus, a detailed knowledge of the soils is needed to prevent detrimental soil changes. The aim of this study is therefore to assess the kind and extent of soil information used in research on floodplains and riparian zones.

Soil Phytomining
Phytomining (PM) is defined as the process of using plants capable of bio-extracting metals from soil in order to explore them economically. This relatively new, innovative method has been gathering significant attention in both the academic and commercial domains. Conventional mining methods are often economically unviable when applied to lean ores, and they can lead to secondary pollution in soil—a situation that applies to all excavated metals. On the other hand, PM is an environmentally friendly and economically viable solution that addresses the growing demands for metal resources, while simultaneously contributing to energy production by harnessing biomass energy.

Soil Nanoremediation and Mushrooms
Soil pollution is a serious challenge facing the global community. This pollution is a direct and/or indirect harmful deterioration, which penetrates all aspects of our life, especially human health. Therefore, there is an urgent need to repair, remove, or decompose these pollutants according to various approaches. Concerning the relationship between soil nanoremediation and its mushrooms, this process can be called nano myco-remediation. The mechanism of this kind of remediation depends mainly on the enzymatic system of mushroom species and is involved in the bioremediation of organic environmental pollutants.
