Abstract:
Due to the atmospheric pollution loads that started with the industrial revolution and have increased exponentially in the process that has come to the present day, the natural components of the atmosphere have been damaged and changed. One of the negative return points of this human-made degradation in the natural order is acid rain. Acid rains harm people directly and/or indirectly. One of the indirect effects is the negative effects on the food chain. Acid rains affect agricultural products, however, they affect the products from the soil. As a result, agricultural fields and agricultural products are damaged. The decreasing resources (water, etc.) with global warming and climate change also increase the negative impact on agricultural products. In this study, the negative effects of acid rain on agricultural areas were investigated and it was aimed to put forward the measures to reduce these negative effects.

Abstract:
The areas affected by mining operations are characterized by extremely complex environmental changes that affect all components of the natural complexes. In several cases, radical negative changes (transformations) take place, which cause the formation of the habitat, characterized by changes in characteristics of all components of the natural environment, including geological structure, soil cover, surface and groundwater and atmospheric air, respectively, flora and fauna. This generally leads to a sharp deterioration of ecological conditions, including living conditions of living organisms and human habitation, causing stressful situations, inconveniences, as well as characteristic diseases due to the influence of factors of excessive pollution of components of the natural environment. As one of the objects of the study, the impact zone of mining enterprises within the town of Sibai and its surroundings in the Republic of Bashkortostan was chosen. It is typical for the assessment of occurring changes and other industrial centers and districts located within the vast strip of the Southern Urals. It has been revealed that the greatest damage is inflicted on ecosystems of small rivers, which is caused by both direct and indirect entry of pollutants into them as a result of dissolution, leaching and entry from rock dumps, emissions into the atmosphere, and settling on the surface of soil and snow cover; direct discharge of wastewater into them, etc. It is shown that with the lingering impact of the regional response to global climate change, environmental problems are exacerbated. This calls for urgent measures to restore favorable environmental conditions and address a wide range of economic and social problems.

Abstract:
The prospects of environmentally safe disinfection of urban sewerage using compositions of bactericidal complexes of copper with amino acids and iminodiacetate derivatives of mucopolysaccharides and triglycerides of fatty acids are shown. When they are dosed into wastewater, the complexes penetrate into the structure of Suspended Particulate Matter (SPM) and mucus and within a few minutes bind the structural fragments of pathogens and larvae, which leads to their death with the outflow of cell fluid, the disappearance of fecal odor, cessation of putrification and coagulation of SPM. The complete disinfection is achieved at doses of complexes of 0.8 - 1.5 mmol per 1 kg of dry matter. The composition is dosed into sewage wells. Organo-mineral masses settle from disinfected wastewater. The use of compositions will reduce the negative impact of sewerage on the sanitary-epidemiological and ecological situation in settlements, increase the efficiency of existing treatment facilities and produce organo-mineral masses as commercial products.

Abstract:
Patients with chronic diseases are especially vulnerable on hot days because high temperatures lead to exacerbation of a number of cardiovascular, neurological, autoimmune, and other chronic diseases. Acute SARS-CoV-2 infection has left tens of thousands of Bulgarians suffering from a new chronic disease: Post COVID-19 syndrome. The Bulgarian Cardiac Institute, in trend with innovations, has launched the first worldwide study to establish the relationship between high ambient temperatures and Post COVID-19 conditions. It covers 1310 citizens and was held during the hottest month in history - July 2021. Eight districts in Bulgaria are covered, and for each of them, we calculated a number of meteorological parameters and determined their influence on the persistent signs and symptoms. Shumen District is the district with the highest percentage of citizens with peristaltic complaints (86%) and the most pronounced in terms of severity. This is the area with the lowest average daily maximum temperature (28.44º), the highest average night minimum temperature (20.42º), and the lowest average temperature amplitude (8.02º) for July 2021. It is characteristic that the neurological symptoms (dizziness, headache, impaired concentration, and memory) are predominant at a lower temperature amplitude (Shumen district). Symptoms of the cardiovascular system (shortness of breath, fatigue, palpitations, chest pain) are more commonly reported at higher temperature amplitudes (Pleven district). The results of the study show that high values ​​of ambient temperatures affect Post COVID-19 conditions. The most unfavorable effect is exerted by the high average night minimum temperatures and the small temperature amplitude. Cardiovascular symptoms are particularly pronounced at large temperature amplitudes and neurological at small temperature amplitudes. Post-COVID-19 conditions are unpredictable and patient care continues during the hot months.

Abstract:
From the intestinal microbiota of Colorado potato beetles and their larvae (Leptinotarsa decemlineata), as well as from their feed – potato leaves, 18 bacteria of different species exhibiting antimicrobial activity (56% of the total number of isolated strains) were isolated. The species of bacteria from all three sources of excretion are different. The following 12 species were described for the first time in the gut microbiota of L. decemlineata larvae and imago: Micromonospora phytophila, Neobacillus drentensis, Pseudomonas gessardii, P. poae, P. rhizosphaerae, Pantoea agglomerans, Streptomyces chartreusis, S. clavifer, S. microflavus, S. rishiriensis, S. badius, and S. coelicoflavus. Antimicrobial activity was not previously known for three species (Staphylococcus argenteus, S. camponoticapitis, S. clavifer). Antimicrobial activity against methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Leuconostoc mesenteroides, multidrug-resistant P. aeruginosa, and Mycobacterium smegmatis was revealed. The gut microbiota of Colorado potato beetles can be considered an encouraging source of antibiotic–producing strains that overcome drug resistance of pathogenic bacteria, as well components of biopesticides.

Abstract:
In Africa, the need for energy is growing. When it comes to renewable energy resources in Africa zone, it is unequivocally needed. Many African countries are experiencing development therefore they are shifting to the use of renewable energy. In that view, this study aims to discover the potential impact of renewable energy consumption on inclusive growth in 20 African countries for a period covering 1997 To 2015. To tackle this estimation technique namely Pesaran’s (2007) [1] CD test, Pesaran’s (2015) [2] LM test and Breusch and Pagan’s (1980) [3] LM test, slope homogeneity test, Average Mean Group (AMG), Common Correlated Effects Mean Group (CCEMG) and pairwise granger were employed. Concentration on inclusive growth contributes greatly to the economy size and ensures employment opportunity creation for the society in a different segment, the result of the study indicates that renewable energy consumption significantly impacted inclusive growth in n the selected Africa Countries. Consequently, if countries like Africa prosper in switching to renewable energy, unbelievable gains could be captured in terms of inclusive growth.

Abstract:
Groundwater is considered the only source of water in arid climate regions. Additionally, population growth is stressing the groundwater resources in the study area, especially in these regions leading to excess groundwater exploitation to meet the demands (domestic, and agricultural). Thus, the groundwater level may decline in the future causing a water scarcity problem. In order to overcome this problem, it is worth necessary to perform mitigation measures prior to raising the groundwater level by augmenting the groundwater in the hydrogeological system. Mitigation measures might be reducing the abstraction rate and installing new artificial recharge sites. To assess the potential of these measures, numerical modeling can be applied. Gaza strip aquifer was chosen as a case study due to the following reasons: arid aquifer, significantly stressed due to over-exploitation of groundwater. Different researchers have already proposed different management scenarios considering these mitigation measures, but most of them considered unreliable management scenarios to predict future groundwater. Some of them reduced the abstraction rate which will lead to the loss of agricultural lands. Whereas, the others increased the artificial recharge rate which is unfeasible to implement in the study area for the next 20 years. Hence, we applied numerical modeling in this article to predict the future groundwater level based on these mitigation measures taking into account reliable management scenarios according to the study area’s current situation . The results indicate that combining both reducing the abstraction rate and increasing the artificial recharge is so promising and they were compared with the latter obtained by the previous researchers.

Abstract:
In Zing LGA of Taraba State, the study evaluated farmers’ perceptions of soil erosion and their soil conservation practices. To gather information for the study from the farmers and the farmland, field observation, informal interviews, and the use of research instruments including questionnaires and remotely sensed imageries were all used. These data were analyzed in a Windows and GIS context using SPSS 23. The results indicate that 68% of respondents are men, while 32% are women farmers, 71% of whom are married and 50% of them fall within the 41–50 age range. Additionally, 70% of farmers have large families with a size range of 9 to 12 individuals, and 86% of farmers are literate. High incomes are generated by the farmers. According to the study, 89.1% of farmers have farms on steep to mild slopes and do not see soil erosion as a specific issue on their property. However, because they believed that the loss of arable land was the primary consequence of soil erosion, they kept an eye out for physical indicators (such as soil color) on their farms. Geographically, soil erosion is more likely to occur in the eastern to the north-eastern portion of the Zing LGA. Terracing, shaping ridges, along contours, and mulching are soil conservation techniques that have been employed for a long time and are advised to be continue.

Abstract:
Urban areas have a dual role in climate change· they are major contributors to climate change as they produce more than 70 percent of greenhouse gas emissions and they also accept the impact of it. Urban trees have great value in urban ecosystems because of their role as carbon sinks, so they contribute to climate change mitigation. The aim of this paper is to collect data about the impact of climate change on forestry species in urban areas via the science of phenology. In recent years, via phenology, the observation and study of the effects of climate change are possible, as there appears to be a shift in the start of biological events, and also a change in their duration. These changes in the seasonal activity of plants, from time to time, are a sensitive but perfectly visible indicator of changes in the functioning of ecosystems. Phenology refers to the recording of dates in which different phases of the plant’s life cycle such as budburst, flowering, dormancy, and hibernation have been observed both in species and in plant communities. Temperature, solar radiation, and water availability are the three factors that affect plant phenology. To appreciate the impact of climate change on the phenological stages of forestry species, three Phenological Monitoring Areas (PMA) were created in three urban spaces in Thessaloniki, in December 2020, within the framework of the project LIFE CliVut (Climate Value of Urban Trees) LIFE18 GIC/IT/001217. Each PMA contains 20 species (10 species of trees and 10 species of shrubs), and 100 individuals (5 individuals per species). The monitoring of the phenological stages of the forestry species was carried out throughout a year on a weekly basis according to the protocol that was created in the frame of the project taking into consideration the BBCH scale.

Abstract:
This study aims to examine the determinants of bushmeat consumption in urban areas in Laos. Men consume more bushmeat than women. Job, the government official was the major bushmeat consumer, but there was no proven by statistical approaches from this study we have done. The education of people who consume bushmeat has finished high school level. Ethnic, Lao Loum people have a negative impact on bushmeat consumption, but for Hmong or Lao Theung people, bushmeat is a long tradition of eating and being a major food source. In addition, believing in eating bushmeat can make people healthy is also valid.
