Nowadays, the issues related with environment preservation assume an increasing importance. Progressively, more sustainable solutions/techniques are being developed to combat environmental destruction. The decision to include themes related to the environment in the curriculum of technological courses in higher education aims to promote more sustainable behaviors and in an indirect way, increase the environmental literacy of the population. Thus, this study aims to evaluate the environmental literacy focusing on four topics, i.e., air pollution, water pollution, global warming, and energy resources. For this purpose, a questionnaire was developed and applied to a convenience sample, formed by individuals of both genders, aged between 20 and 81 years old. The questionnaire intended to collect data to characterize the sample and assess the literacy regarding environmental issues. In order to carry out the environmental literacy assessment, the respondents were asked to express their degree of agreement with some statements related with the environmental themes mentioned above. The data collected was analyzed using data mining tools. The results suggest that the population’s literacy is satisfactory in relation to some issues, but insufficient in relation to others, equally important, but less disseminated.

Much of New South Wales and southern Queensland suffered from extreme drought from 2017 to 2019. This study models drought and bushfires impacts using VU‐TERM, a multi‐regional, dynamic CGE model. Prolonged drought pushed national real GDP to 0.7 per cent or more below base in 2018–2019 and 2019–2020. NSW’s real GDP fell relative to forecast by 1.1 per cent or $6.9 billion in 2018–2019 and 1.6 per cent or $10.2 billion in 2019–2020. These impacts reflect a severe diminution of farm output, given that agriculture accounts for around 1.6 per cent of NSW’s income. Bushfires exacerbated 2019–2020 losses. We assume that there is a full recovery in seasonal conditions in 2020. However, prolonged drought and bushfire destruction deplete farm capital through depressed investment and diminished herd numbers. Consequently, the income earning capacity of farms in recovery remains below that of a no drought base. The net present value of the national welfare loss is $63 billion, split between $53 billion in losses from drought and $10 billion from bushfires. The latter excludes any valuation of human lives lost, flora, fauna or forestry destruction. In the longer term, adaptation and policy responses will need to reflect the expectation of increased frequency of adverse climatic events.

The aim of this paper is to explore the relationship between energy use, economic growth, and environmental pollution in Turkey for the period from 1968 to 2016 by using ARDL bounds test approach. Test findings show that an increase in economic growth and trade openness cause environmental degradation in all models. Although the energy consumption coefficient is positive in all models, it is statistically significant only in the model where the ecological footprint indicator is the dependent variable. Thus, while determining a positive relationship between environmental pollution and economic growth in Turkey, also it can be said that the energy consumption increases ecological footprint. The findings indicate that there is a need to consider not only pollution emissions but also the ecological footprint for environmental degradation. These results raise a number of policy recommendations for Turkey. The existence of an inverted-U shaped relationship between environmental degradation and economic growth actually demonstrate the successful long run sustainable growth in Turkey.

The global structural change, together with "the green revolution", caused the economic growth to be based on the service sector today, instead on the traditional economic sectors. The main focus of this paper is on the factors that affect the decisions of households in Serbia to participate in the tourism industry in the context of the sustainable development. In particular, a significant portion of the analysis is devoted to the constraints that can be induced by inadequate drinking water supply and its quality in households. These factors can be considered the main limitations to those households that decide to provide accommodation and food services to the tourists in their local touristreceiver communities. The empirical analysis is based on survey data that describe conditions in the households, whereas the econometric framework is employed in order to determine structural relationships. The null hypothesis that drinking water supply and quality do not affect the likelihood of the household participating in the tourism industry is tested and accepted based on the probit model estimates. The difference between the public urban and local water supply systems that provide drinking water to the households is statistically confirmed, but it does not affect the likelihood of the household participating in the tourism industry.

Sustaining agricultural demands is a typical problem, particularly in locations afflicted by the scarcity of fresh water, poor farming soil, and hot weather. The main goal of this study is to perform a thermodynamic analysis of an integrated multigeneration system containing a direct contact membrane distillation crystallization system that recovers beneficial hydroponic farming nutrients from seawater using renewable energy resources. A parametric study is carried out to determine the impacts of various factors on the system, such as changing the rate of mass flow rate, recovery ratio, and salinity. This study proposes a novel sustainable multigeneration system for seawater desalination and ions recovery using the direct contact membrane distillation crystallization system to provide the hydroponic solution and greenhouse ventilation using the dual evaporator vapor compression refrigeration system. With overall exergy efficiency and energy efficiency of 41.40%, and 39.80%, respectively, the system requires about 1182.69 kW and 5314.6 kW of electrical and thermal power in total, respectively, to desalinate 5 kg/s of seawater and recover 170 mg/s of Sulfate (SO4), 81.28 mg/s of Magnesium (Mg), 25.48 mg/s of Calcium (Ca), and 24.16 mg/s of Potassium (K), yielding about 4.4 kg/s of a hydroponic solution, and ventilating 25 greenhouses with a volume of 600 m3 of single greenhouse.

The geography of Kazakhstan is characterized by a diverse landscape and a small population. Therefore, certain automobile roads pass through unpopulated mountain regions, where physical road diagnostics are rare or almost absent, while landscape factors continue to affect the road. However, modern geo-information approaches and remote sensing could effectively provide the road diagnostics necessary to make timely control decisions regarding a road’s design, construction, and maintenance. To justify this assumption, we researched the deformation of a mountain road near Almaty city. Open access satellite images of and meteorological archival data for the region were processed. The resulting data were compared to validate the road’s deformation triggers. Extreme weather conditions’ impacts could be identified via road destruction (nearly 40 m longitudinal cracks, 15 m short transversal cracks, and two crack networks along a 50 m road section). The remotely sensed parameters (vertical displacement velocity, slope exposure, dissections, topographic wetness index, aspect, solar radiation, SAVI, and snow melting) show the complexity of triggers of extensive road deformations. The article focuses only on open access data from remote sensing images and meteorological archives. All the resulting data are available and open for all interested parties to use.

To cope with biodiversity and climate change challenges, Education for Sustainable Development (ESD) needs to emphasize knowledge that considers multiple perspectives. Optimizing teacher education requires knowledge about the prerequisites of student teachers. The latter includes content knowledge with respect to Sustainable Development (SD). Apart from situational and conceptual knowledge, procedural knowledge (containing solution strategies) is of special interest, but it is much more difficult to measure. Thus, this study aims at developing a refined procedure to measure SD-relevant procedural knowledge and to define a measure for such knowledge, including a suitable benchmark for its evaluation. As SD-relevant knowledge, the SD challenges biodiversity loss and climate change were focused on. For operationalizing these challenges, the highly relevant contexts insects and pollination and peatland use were chosen. For both SD challenges and contexts, potential solution strategies were identified by a literature review. A procedure was then tested to measure procedural knowledge. The procedure includes a two-round expert survey (Delphi approach) with an in-between think-aloud study with student teachers. The described innovative procedure resulted in a measure (18 items) to assess procedural knowledge of student teachers via effectiveness estimations of provided solution strategies. This measure contains procedural knowledge items that are related to prior presented scenarios regarding the two contexts and a benchmark to evaluate these items. The benchmark derives from the second round of the Delphi study. The procedure and the developed final instrument include expertise from multiple disciplines such as ESD, SD, biodiversity, insect and pollination, climate change and peatland use. The sophisticated procedure can be transferred to challenging measurement developments. Furthermore, the measure provided for SD-relevant knowledge can be applied to other target groups in upper secondary and in higher education within ESD.

Rural planning is in a state of flux, covering a range of topics. The objectives of planning have evolved over the years. To get an overview of the evolving themes and narratives on rural planning in China, a literature review is conducted here using text mining considering 145 papers published in Web of Science. Attention is given to trends over time in terms of the topics covered. Six evolving themes are revealed, namely: providing affordable and decent life under industrialization and urbanization progress, national ecological programs and practices, building a new (socialist) countryside and rural−urban relationship in planning, land planning and restructuring, rural tourism planning and activities, and other themes. It is highlighted that strategies and knowledge of “development” are a common instructional epistemology among agro-industrialism, agro-ruralism, scientific rationalism, and “economy oriented” humanism.

Despite strong interest and conflict research spanning multiple disciplines, connections between water flows and conflicts remain unclear, due to incomplete datasets on water-related conflict-cooperation events and poor understanding of socioeconomic and biophysical causes of such conflicts. The dataset on water-related conflict-cooperation events compiled in this study extends to 2019, updating previous datasets that covered only up to 2008, yielding important new insights on cooperation-conflict trends. Global and regional trends were analyzed using the new events dataset, together with changes in hydroclimatic variables and population density. The analysis revealed that water-related cooperation was far more common than conflicts across all regions, in both drier and wetter climates, indicating that abundance and lack of water can both promote cooperation. However, conflict events were more common in drier climates where water is scarcer. This cooperation-conflict balance shifted in the 2000s, with conflict events increasing, to outnumber cooperation events in 2017. The main shift occurred in Africa and Asia, where increased conflicts in Africa coincided with a prolonged period of below-average precipitation and severe drought, while the shift in Asia coincided with increased evapotranspiration caused by human activities and increased population density. Differences between regions were confirmed by event descriptions, with events in Africa relating to water access and farmer-herder conflicts, and events in Asia relating to irrigation and dam construction. These differences highlight the need for regional-scale analysis of water-related conflict-cooperation trends and pathways. With climate change and human activities expected to increase, the increasing trend in conflict events could persist, with water resources becoming a more frequent cause of future conflict. Identifying these complex cooperation-conflict changes is vital in determining future actions required to reduce conflict events and promote cooperation on water.

INTRODUCTION. Climate change is the most important megatrend, which has a multiplier effect on the following: sovereignty of States (especially in contrast to the example of small island developing States whose territories may soon disappear – “to go under water”), forced displacement of the population both within States and outside (“environmental refugees”, “climate refugees”), increasing pressure on natural resources, increasing the number of natural disasters, desertification and water deficiency. It is possible to combat climate change only jointly at the international level and in accordance with international law. Since the problem of climate change has recently been discussed in the international field, there is an urgent need to create new instruments in international law and to adapt existing instruments. As a result of the consensus of positions of developed and developing States in 1992, the UN Framework Convention on Climate Change, then in 1997 by the Kyoto Protocol, and in 2015 – the Paris Agreement. Dozens of decisions are issued at the annual Conferences of the parties to these international agreements, which have a recommendatory force, but which have a significant impact on the maintenance of the international regime for combating the climate change. Furthermore, in various branches of international law (international human rights law, international economic law, international air law, international maritime law), mandatory and recommendatory acts are adopted to prevent climate change and adapt to the happened changes. MATERIALS AND METHODS. This study is based on a significant amount of materials, including international legal acts, recommendatory acts, national legislation of the Russian Federation, as well as modern doctrinal studies of Russian and foreign authors. The methodological basis of the research is the general methods of cognition (method of logical and systematic analysis, dialectical method, methods of deduction and induction) and specific methods of science (historical legal, comparative legal and formal legal methods, method of legal modeling and forecasting), and the method of legal forecasting. RESEARCH RESULTS. In this research the author analyzed various international mandatory and recommendatory instruments summarized the doctrinal positions of Russian and Western legal scholars and set out in domestic and foreign scientific literature, proposed amendments to Russian legislation to comply with international law in the field of combating climate change. The article summarizes the approaches under consideration and draws conclusions regarding the positioning of the Russian Federation and the United States in relation to the formation of an international legal regime for combating climate change. DISCUSSION AND CONCLUSIONS. International legal documents on combating climate change, both binding and recommendatory, are adopted in the field of international environmental law, international human rights law, international air law, international maritime law, international economic law. This shows that today there is an international legal regime to combat climate change. The combating climate change is closely interconnected with the Sustainable Development Goals (2016–2030), which should also be taken into account in the implementation of international and national law. Moreover, not only States and international intergovernmental organizations, but also non-governmental actors (large cities, TNCs, NGOs) are being called to implement the provisions of international legal instruments. It is concluded that there is a necessity to closely monitor the ongoing changes in the international field in the fight against climate change, the participation of the Russian Federation in them in order to develop their own position regarding the regulation of various issues related to combating climate change.
