The paper presents a syntaxonomic and floristic analysis of salt marshes formed at the soda factories in Mątwy and Janikowo, the salt mine in Góra, and the salt works and spa hospitals in Inowrocław. In the study area delineated in this region, the analysis also covered salt marshes formed in places of failure of pipelines supplying brine to industrial, medical and recreational facilities, as well as those discharging saline industrial and municipal wastewater were also analysed. A total of 611 relevés were taken using the Braun-Blanquet method in 215 inland salt marshes occurring in the study area during four consecutive growing seasons (1998-2001). A numerical classification of this set of relevés and of 124 taxa of vascular plants recorded in these relevés was carried out using TWINSPAN. Taxa from the prepared floristic list were assigned to five geographical and historical groups, and the percentage of species of these groups was determined for the saltmarsh flora of the study area. It was found that most of the groups of relevés distinguished at successive levels of hierarchical divisive classification, performed based on differential species, correspond through their species composition to six (out of seven) syntaxa of halophytic vegetation distinguished in the studies conducted about 40 years ago in the entire area of Kuyavia. Of the total number of 124 taxa, 14 species of halophytes were identified, including six obligate and eight facultative ones. The number of taxa in the geographical and historical groups was as follows: 22 spontaneophytes, 73 apophytes, 16 archaeophytes and six kenophytes. No diaphytes were found in the study area, however, seven species of cultivated plants were recorded.

This study aims to analyse the possibility of exploiting agricultural waste in Libya to produce biochar and methane gas, and to evaluate the technical, economic and environmental aspects associated with this technology. In this study, the focus was on seven agricultural projects located in the Libyan desert, where these projects contain many varieties of Crops. A region with a total area of 5.36×106 ha was explored from Benghazi to Dernah eastward including the Green Mountain (Libya). For literary analysis, peer-reviewed scientific publications for 2018-2023 were selected from reliable bibliometric databases Scopus, Google Scholar, ScienceDirect, PubMed, since these databases have the greatest coverage of peer-reviewed publications. To study the biomass potential of the region, the Bioenergy Tool developed by IRENA was used. The study showed that agricultural residues available in Libya can be used Libya, such as grain straw, palm trees, and others, in the production of biochar and methane gas, using pyrolysis techniques to convert agricultural waste into biochar and methane gas. The study indicates that this technology can be cost-effective and environmentally effective, and that many environmental and economic benefits can be achieved, such as improving air quality, increasing agricultural land productivity, and providing new job opportunities.

Groundwater is one of the essential freshwater sources for human consumption, with the highest reserves of fresh water on earth after glaciers and glaciers. Conservation and maintenance of groundwater quality in a large area require an overview of the status and potential of groundwater resources in that area, which can be applied to potential areas using remote sensing technology. In this study, after extracting the factors influencing the formation of groundwater aquifers from the Sentinel satellite image, appropriate information layers were prepared and integrated into the ArcGIS using different fuzzy operators and potential maps prepared with the location of groundwater wells. The area was validated. The results of combining slope layers, slope direction, lithology, drainage length density, lineament length density, lineament buffer, drainage buffer, and vegetation in the area showed that fuzzy multiplication and gamma operators could be used as suitable operators for Introducing information layers to identify groundwater potential in the area. Also, using the gamma numbers 0.1 gave better results than larger gamma numbers. The research results showed that 15.9% of the studied area has good and very good potential for the presence of underground water in the production map using the fuzzy gamma with gamma 0.1 method. Also, this map was validated by 70.1% of water wells in the region. The normalized ratio of accuracy to validity in the final production model with this method was estimated to be 54%, which is entirely acceptable compared to other methods.

In the fast urbanizing world, it has become vital to study urban ecology so as to understand where and how anthropogenic activities impair the urban environment, including air quality; and how living conditions can be improved by urban planning without mortifying urban ecology. This may require innovative technological ideas to efficiently and judiciously utilize the limited urban space. Air quality mapping using Geographic Information System (GIS) provides one such effective tool to urban planners to identify and target specific areas for air quality management in urban setting. In the present study, the air quality mapping of a well-planned city of Chandigarh (India) with proper environmental management zoning has revealed that the air quality index (AQI) of the city falls under “Moderately Polluted (101-200)” category primarily due to annual average concentrations of (range: 44.17-68.87; overall: 56.64) and (range: 99.32-129.39; overall: 111.92) being higher than the permissible levels of 40 and 60 respectively as per Indian standards at all locations as well as for overall city. The study has identified vehicular traffic as the primary reason responsible for the moderately polluted air quality of the city that has the highest vehicle density (878 per 1,000 population) in India. The paper has also suggested measures that may be incorporated during designing and developing the physical and social infrastructures in the city so as to judiciously and efficiently utilize the limited urban space.

The water quality of Yamuna River was studied for four years from 2019 until August 2022. The period witnessed the onset of COVID-19 pandemic and government-imposed complete lockdown which caused slight improvement in the water quality. Five parameters pH, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen (DO) and Faecal Coliform (FC) monitored by Delhi Pollution Control Committee (DPCC) were analyzed to see the changes in water quality of Yamuna River in the Delhi stretch before the onset of COVID-19 (2019), during the COVID-19 (2020 and 2021) and after the pandemic (2022). Maximum improvement in some water quality parameters were observed only during the 1st lockdown in the year 2020 when government had imposed complete restriction on the movement of people and industries were not functioning at there maximum capacity. The water quality again declined in the year 2021 and further in the year 2022. Major cause of pollution was the untreated waste reaching the river from various drains. Therefore, it is extremely important to intersect all the major and minor drains through Sewage Treatment Plants (STPs). The floodplain of the river needs to be managed to keep the pollution in control.

The issue of the land degradation vulnerability index (LDVI) is multifaceted, encompassing climate, soil, vegetation, policy formulation, and human actions. In Vietnam, the convergence of climatic fluctuations and human impact results in phenomena, such as soil sealing, erosion, salinization, and landscape fragmentation. These phenomena are recognized as significant triggers of land degradation. This paper seeks to present a method for assessing a land's susceptibility to degradation by utilizing ten ecological 10 criteria: NDVI; slope; bulk density (cg/cm3); cation exchange capacity in the soil (CEC; mmol(c)/kg); Soil organic carbon stock (SOC; dg/kg), pH; Nitrogen (N; cg/kg); soil thickness (cm); soil surface temperature LST (0C); precipitation of the driest quarter (mm). The research results show that Song Hinh and Son Hoa communes are standing on the most land degradation vulnerability. Some criteria that are considered important in assessing land degradation by the analytic hierarchy process (AHP) technique are NDVI, followed by slope, nitrogen, bulk density, and soil thickness. The results of the study are consistent with records in localities that are often under pressure from drought. Extreme LDVI areas were larger identified on low mountains, slope terrain, and precipitation of driest quarter under 200mm, expanding on the agricultural areas with 40km2 total province agriculture area, followed by grassland (20.3 km2), natural forests (17.2 km2), plantation forests (8.2 km2), residences (8.2 km2), and bare land (8.15 km2). Poor land management practices, such as improper construction, inadequate water management, and lack of terracing, can contribute to soil erosion and land degradation. This LDVI assessment process can be applied to some tropical countries. The NDVI index combined with the slope, nitrogen, bulk density, and soil thickness can be exploratory indicators of land sensitivity to land degradation.

In the present study, our aim was to document the traditional knowledge regarding ethno-medicinal plants used by the Jadh-Bhotiya community in the Uttarakashi district (Uttarakhand, India). A total of 54 taxa, belonging to 49 genera and 31 families, were recorded with medicinal properties. Lamiaceae, Liliaceae and Orchidaceae were the dominant families (in terms of number of species), while the top genera included Berberis, Habenaria, Malaxis and Polygonatum. Herbs constituted the dominant life form (82%), followed by shrubs and trees (9% each). Roots (20%) and the whole plant (13%) showed a higher proportion of use for medication. Powder (33%) and paste (20%) were the most frequently used drug preparation methods. Regional conservation assessment analysis revealed that 76% of the species were recorded under the 'Least Concern' (LC) category, followed by 'Vulnerable' (VU) with 13% of the species, and 11% of the species were recorded under the 'Near Threatened' (NT) category. Aconitum heterophyllum, Arnebia benthamii, Nardostachys jatamansi, Rheum australe, Saussurea obvallata and Taxus wallichiana were recorded under the ‘Near Threatened’ (NT) category. Angelica glauca, Carduus edelbergii, Dactylorhiza hatagirea, Ephedra gerardiana, Lilium polyphyllum, Malaxis acuminata, and Malaxis muscifera were recorded under the ‘Vulnerable’ (VU) category, while the remaining species were recorded under the ‘Least Concern’ (LC) category. The knowledge about therapeutic information concerning plants in the study area and elsewhere is diminishing day by day. Regional-level conservation status of plant species can be helpful in the global conservation status assessment. It is recommended that conservation measures be applied for the betterment of those species falling under various conservation categories, especially the threatened ones. Additionally, more ethno-medicinal studies are recommended in such remote regions to further enhance our understanding of traditional medicinal practices and contribute to the conservation of indigenous plant knowledge.

Urban environment carries complex land-use and land cover (LULC), similarly Karachi as a metropolitan have multifaceted LULC and compact infrastructure. This study seeks to assess the impact of infrastructure of urban environment at mega city Karachi Pakistan. Approximately, fifteen different locations of metropolitan with different surroundings were evaluated based on the studied variables of surrounding such as temperature, humidity, formaldehyde (HCHO), total volatile organic compounds (TVOC) pollution, fine particulate matter (PM2.5) in air i.e., air quality, maximum noise pollution and minimum noise pollution were investigated. The readings have been collected through relevant instruments and the results have been generated through interpolation in ArcMap 10.8. The obtained results revealed that the physical factors affect the temperature and humidity conditions of the study area. While environmental and noise pollution depends on the surroundings, e.g. industrial surrounding effects on air quality, i.e. 180 recorded at industrial region of Korangi, while construction sites are catalysts of noise pollution and highest noise pollution are recorded at North-Nazimabad. Cancer causing substance, i.e. formaldehyde found along the petrol pumps, airports and transportation junctions ranges up to 0.99 ppm near Jinnah International airport and mass transit location of Shahrah e Faisal. While total volatile compound pollution has been found along the Malir catchment area, i.e. 0.4 mg/m3. The lifestyle of Karachiites need to be transform there is a dire need to think about physical and mental concord of the citizens of metropolitan. Similarly, government should play some positive actions and introduced green and environmental friendly technology to control air and noise pollution.

This study seeks to assess the impact of infrastructure of urban environment at mega city Karachi Pakistan. Approximately, fifteen different locations of metropolitan with different surroundings were evaluated based on the studied variables of surrounding such as temperature, humidity, formaldehyde (HCHO), total volatile organic compounds (TVOC) pollution, fine particulate matter (PM2.5) in air i.e., air quality, maximum noise pollution and minimum noise pollution were investigated. The readings have been collected through relevant instruments and the results have been generated through interpolation in ArcMap 10.8. The obtained results revealed that the physical factors affect the temperature and humidity conditions of the study area. While environmental and noise pollution depends on the surroundings, e.g. industrial surrounding effects on air quality, i.e. 180 recorded at industrial region of Korangi, while construction sites are catalysts of noise pollution and highest noise pollution are recorded at North-Nazimabad. Cancer causing substance, i.e. formaldehyde found along the petrol pumps, airports and transportation junctions ranges up to 0.99 ppm near Jinnah International airport and mass transit location of Shahrah e Faisal. While total volatile compound pollution has been found along the Malir catchment area, i.e. 0.4 mg/m3.

Incorporating flowering plants into cropping systems has the potential to actively enhance pollination and crops yields. This study evaluated whether the introduction of border planting affects bee visitation and yield of a broad bean (Vicia faba L.). Experiments were carried out in 2018 and 2019 in Ismailia, Egypt. Bee visitation and broad bean yields were compared between plots with and without border planting. Results showed that open flowers achieved higher yields than netted flowers. Apis mellifera L. was the dominant visitor, followed by four solitary bee species, Chalicodoma siculum (Rossi), Colletes lacunatus Dours, 1872, Andrena ovatula and Xylocopa pubescens (Kirby, 1802). The addition of border planting was associated with a significant increase in the abundance of all five bee visitors and the associated yields. Findings showed that flowering border plants adjacent to broad bean can actively enhance pollination services and yields of this commercially valuable crop, whilst helping to conserve vulnerable bee populations.
