The article is devoted to the study of the life potential support of the population, which reflects living conditions of the population in specific geosystems (on the example of the Sumy region, Ukraine). The main purpose of the article is to assess the geo-ecological potential of the regional landscape structures, namely the landscape districts of the Sumy region. The article highlights the theoretical and methodological foundations of the geoecological potential research, substantiates the theoretical aspects of the of “geo-ecological potential” concept, describes in detail the methodology of assessing geo-ecological potential, which is evaluated on the basis of natural geosystem potential, geosystem sustainability potential and technogenic geosystem load. The assessment of the natural potential of the Sumy region landscape districts (based on the humidity coefficient, the sum of active temperatures above 10°C, hydrothermal potential of phytomass productivity, annual precipitation, adverse natural processes such as landslides, flooding, rising groundwater levels, erosion, dry winds, hail, fogs) is conducted and the levels (low, below average, average and high) of the natural potential are defined. Three districts of the environmental sustainability of the regional landscape districts are established on the basis of component-by-component assessment of the meteorological potential of the atmosphere, surface water and soil sustainability potential, as well as biotic potential: below average, average and above average. The indicators of the population density of the region, coefficient of the territorial production concentration, economic development of lands (agricultural lands, built-up lands and open lands without vegetation), environmental pollution of the region (radiation and chemical air pollution, pollution of natural waters and soils) and the integrated indicator of technogenic load, which allows to establish the following levels of the technogenic load on the landscape districts of the region: below average, average and above average, are analyzed. Particular attention is paid to the assessment of the geo-ecological potential, which allows to establish 5 levels, of which only 3 are presented in Sumy region, based on which areas of geo-ecological potential of the landscape districts are identified: below average, average and above average and a map of the geo-ecological potential areas is created. It is established that the indicator of the geo-ecological potential of the landscape districts of the Sumy region ranges from 0.05 Psel-Vorskla landscape district (below average level) to 1.07 Esman’-Kleven’ landscape district (above average level). It is established that the higher the values of the natural potential and sustainability of the natural environment and the lower the indicators of technogenic load, the higher are the values of the geo-ecological potential.

Persistent organic pollutants have been increasingly detected in natural waters, and this represents a real challenge to the quality of this resource. To remove these species, advanced treatment technologies are required. Among these technologies, Fenton-like and photo-Fenton-like processes have been investigated for the removal of pollutants from water. Delicate aspects of photo-Fenton processes are that light-driven processes are energy intensive and require a fair amount of chemical inputs, which strongly affects their overall environmental burdens. At present, aside from determining the efficiency of the processes to remove pollutants of a particular technology, it becomes fundamental to assess also the environmental sustainability of the overall process. In this work, the methodology of the life cycle assessment (LCA) was applied to identify the hotspots of using magnetite particles covered with humic acid (Fe3O4/HA) as a heterogeneous photo-Fenton catalyst for water remediation. The sustainability of the overall process was considered, and a comparative LCA study was performed between H2O2 and persulfate activation at different pH. The addition of humic substances to the particles allows the effectiveness of the catalyst to improve without increasing the environmental impacts; these processes are strongly correlated with energy consumption and therefore with the efficiency of the process. For this reason, working at acidic pH allows us to contain the impacts.

Geographically, the Untung Jawa island is located at the Seribu Islands region, a maritime tourism spot at the<br />north of Jakarta.  The development of new infrastructures in the island would benefit to not only for tourism,<br />but also the activities environmental sustainability in the area. A sustainable tourism development must touch<br />three important aspects: First, economic, social and environment which are inter-related to each other. If not<br />carried out in a balanced way, then it could possibly damage the infrastructures around the tourism area, such<br />as breakwaters, piers and the whole environment. In conclusion, it is important to map the characteristics of<br />the infrastructure damage around the Untung Jawa Island, as well as the urgency to update the information<br />about the ecology of the islands without forgetting the government’s role to develop the island by considering<br />the characteristics of the infrastructure, local and ecological potential.   <br /> <br /><br />

Understanding natural variations of Rn (222Rn) concentrations is the fundamental prerequisite of using this radioactive gas as a tracer, or even precursor, of natural processes, including earthquakes. In this work, Rn concentrations in groundwater were continuously measured over a seven-month period, during 2017, in the Giardino Spring, Italy, together with groundwater levels in a nearby well installed into a fractured regional aquifer. Data were processed to reduce noise, and then analyzed to produce the Fourier spectra of Rn concentrations and groundwater levels. These spectra were compared with the spectrum of tidal forces. Results showed that diurnal and semidiurnal cycles of Rn concentrations, and filtered oscillations of groundwater levels, in the nearby well, are correlated with solar and luni-solar components of tidal forces, and suggested no correlation with the principal lunar components. Therefore, influencing factors linked to solar cycles, such as daily oscillations of temperature and atmospheric pressure, and related rock deformations, may have played a role in Rn concentrations and groundwater levels. An open question remains regarding the correlation, which is documented elsewhere, of Rn concentrations and groundwater levels with the lunar components of the solid Earth tides.

Urban management is a new terminology in global urban planning, actively influencing the indicators of environmental sustainability and actions in relation to various climate risks on the planet. Experts consider different types of technologies as an opportunity to manage urbanization at the global level and predict the situation in the socio-economic and environmental spheres of life. On the other hand, the increasing risks on the planet from floods, hurricanes, fires and droughts force specialists to adapt to these changes, learn how to control them through new design technologies. Therefore, the emergence of the term “urban management” is not accidental and is associated with a change in the perception of the level of sustainability of the environment, the comfort of living for people of different ages and social status in large cities. In this regard, the assessment and meaning of such well-known concepts as “Sustainable City”, “Green City”, “Smart City” changes somewhat. Their content is filled with a new meaning if the technological aspect is added to the socio-economic and environmental aspects of sustainable development, as an independent concept associated with the restoration of the natural potential of cities by technological means. Therefore, the article will consider the problems of restoring nature and urbanized territories through the use of ecological technologies that simulate natural processes with different typological content: from the restoration of biotopes to the accumulation of rainwater in the body of the natural landscape.

Green infrastructure (GI) includes an array of products, technologies, and practices that use natural systems—or designed systems that mimic natural processes—to enhance environmental sustainability and human quality of life. GI is the ultimate source of the ecosystem services which the biotic environment provides to humanity. The maintenance and enhancement of GI to optimise the supply of ecosystem services thus requires conscious planning. The objective of this thematic issue is to publish a cross-section of quality research which addresses how urban planning can contribute to the conservation, management, enhancement, and creation of GI in the city. The terms of reference include the technical, economic, social, and political dimensions of the planning/GI nexus. Here we offer a brief overview of the articles published in this collection, and consider where policy, planning, and design relating to urban GI may be heading in the future.

ABSTRACT Simplified microbial communities, or “benchtop microbiomes,” enable us to manage the profound complexity of microbial ecosystems. Widespread activities aiming to design and control communities result in novel resources for testing ecological theories and also for realizing new biotechnologies. There is much to be gained by reconciling engineering design principles with ecological processes that shape microbiomes in nature. In this short Perspective, I will address how natural processes such as environmental filtering, the establishment of priority effects, and community “blending” (coalescence) can be harnessed for engineering microbiomes from complex starting materials. I will also discuss how future microbiome architects may draw inspiration from modern practices in synthetic biology. This topic is based on an important overarching research goal, which is to understand how natural forces shape microbial communities and interspecies interactions such that new engineering design principles can be extracted to promote human health or energy and environmental sustainability.

Intensive rural industry is developing rapidly in parts of inland Australia. The usually nutrient and salt rich effluent from these sources has traditionally been disposed to both land and water bodies. Since direct water discharge is no longer permitted, a challenge now exists when applying effluent to land especially where the rate of application exceeds crop requirements. Effluent of high volume and concentration of nutrients and/or salts can easily contaminate land and water resources. Predicting the optimum rate of land application of effluent is complicated by the physical, chemical and biological properties of soils. This paper addresses the characteristics of effluents from various intensive rural industries and their potential environmental impacts when irrigated to agricultural land in New South Wales, Australia. To assess the environmental sustainability of effluent reuse in land application, a mathematical model (ERIM) has been developed based on a monthly water balance. ERIM includes historical rainfall and evaporation; the amount of nitrogen and phosphorus introduced; their yearly removal by plants to be grown; amount of applied organic matter; and water holding capacity of soil.
