The data on the frequency, density and abundance of the lichens growing around the Moghla Coal mines, Kalakote has been recorded and compared with lichens growing in a forest area away from the coal mines to work out effect of coal mines on the diversity and distribution of lichens. The data revealed that pollutants released by the open coal mining activities not only effected qualitative distribution but also have effect on the quantitative parameters. Over all 10 species of lichens belonging to 9 genera and 6 families have been recorded from the vicinity of coal mines as compared to 15 species, belonging to 9 genera and 7 families, recorded from the forest area.

The Difference

Abstract This study is focused on the changing of areas of water bodies in selected villages of the Pilsen Region (Czechia). We researched several different types of rural settlements and three time horizons with the help of old maps, orthophoto maps and GIS tools. To capture the influence of their location within the urban system, we chose 15 places from four categories (inner suburban area, outside suburban area, rural area, periphery rural area) depending on their distance to the core of the Pilsen agglomeration. There is no significant change in the amount of water bodies between the first reference period (1838-1839) and the second period (1957-1963) in the selected settlements. However, the third period (2013-2015) is characterized by the emergence of a large number of small water bodies - swimming pools and garden ponds. Based on the results of our research we identified the declining importance of public water bodies in some of the settlements. However, we have identified a notable prevalence of garden ponds which have a more positive ecological impact than pools. The proportion of private water bodies (covered and uncovered pools and garden ponds) in the total area of water bodies in the rural settlements in most cases is less than 20%, in the suburban settlements up to 100%. Peripheral settlements have a below-average share of these water bodies. The difference between the number of pools in different settlements is related to the proportion of newly built houses there. Although there are relatively fewer pools in rural settlements, the difference compared to the situation in suburban settlements is not pronounced due to the change in lifestyle in rural areas and the change in functions of some villages to recreational areas. Influence of pools on water consumption is dependent on the individual exchange technology of water in swimming pools. Filling of the pool before the season can overload the capacity of the local water supply.

AbstractIn order to protect the offshore environment and strengthen the comprehensive rectification of sewage outfalls, an evaluation method of regional sewage outfalls by combining the marine numerical simulation and comprehensive evaluation technology was constructed, considering the marine environmental capacity and the ecological impact of sewage discharge from outfalls on the marine eco-environment sensitive areas. Then the layout rationality of each outfall was evaluated and the discharge scale was optimized with a case study of existing sewage outfalls in Xiamen. The results show that, the comprehensive evaluation score of Yundang outfall was 3 points in 2025, evaluated as the outfall with irrational layout. In 2035, the comprehensive evaluation scores of Fenglin and Dalipu outfalls were 3 and 2 points respectively, evaluated as the outfall with irrational discharge scale. It is suggested to control the scale of expansion or increase the reclaimed water reuse rate in Jimei and Gaoqi Wastewater Treatment Plants. This method has enriched the evaluation system for layout optimization of sewage outfalls, providing scientific supports for comprehensive improvement of sewage outfalls and marine environmental management.

Outdoor sport events evidently have an impact on the environment. If they are taking place in naturally protected areas this impact is even greater. By taking ’Le Grand Raid Réunion’, an international ultramarathon annually organized in the heart of an UNESCO World Natural Heritage site, as a case study, this paper concentrates on assessing the ecological impact of an outdoor sports event in a protected natural site. On the basis of datasets taken from official logistics lists and from a survey conducted among all event participants the analysis embraces ecological and carbon event footprinting. Measuring those two indicators allows identifying the specific event-related ecological impacts, including diverse variables caused by the athletes, the spectators, and the related organizational requirements. The results of the study thereby have the ability to strongly influence the future event policy and to function as a model for the assessment of the ecological impact of other outdoor sports events.
