Teachers and curriculum is the key ingredient to educate children and teenagers to be leaders of tomorrow in protecting the environment. This quantitative study was conducted to examine elementary school students' knowledge and attitudes towards environmental issues in Rawalpindi. The environment is directly and indirectly affected by humanity. The environment is getting polluted day by day due to which it becomes difficult to live in such a massive environment. To achieve this, there is a need to develop knowledge and attitudes in each individual. For this purpose, the population of the study consisted of all the public and private schools of the Rawalpindi. A hundred students of the ten schools, five public and five private schools of Rawalpindi, were taken as a sample for data collection. To check the attitudes of students' the questionnaire-based Relevance of Science Education (ROSE) Project was used to measure a student's attitudes and to measure the knowledge of students' self-made knowledge assessment test was used to collect the data from 7thgrade students'. The study examined the knowledge and attitude of elementary school students in public and private schools. The study also checked and compared students' knowledge and attitudes in public and private schools of Rawalpindi. Data was analyzed on SPSS software; Cross tabulation and chi-square were used to check students' knowledge. The Independent t-test was used to measure the attitudes of students. The results indicated no significant difference between government and private school students' knowledge and attitudes. Private school students' had slightly more knowledge than public school students but this difference was not significant. The public and private school students had a positive attitude towards environmental issues. Students owned environmental problems and were highly motivated to solve these problems. They were agreed to take action for the betterment of the future. As a result, sustainable development from elementary school to university necessitates a paradigm shift in our educational systems. Indeed, a sustainable way of life is impossible to achieve without a proper education system that teaches our youth how to integrate sustainability principles into their daily lives and work. Significant progress has been made in integrating environmental values into current curricula, developing new approaches and producing educational content for effective EE implementation in both programmes, since it was a government initiative to integrate environmental concepts into established curricula, devise different approaches and prepare training materials for ef Teacher teaching is therefore important in both Pakistani education systems to improve vital thinking skills and to react positively to the world about pot","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42702767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonetheless, its improvement does not necessarily guarantee that environmental quality can be preserved. Hence, it is the objective of this study to examine the effect of logistic improvement on environmental degradation in developing countries. Applying dynamic panel model estimator for a panel of 50 developing countries for the period between 2010 and 2016, this study observes that the level of pollution tends to be higher with a higher level of logistic performance. The findings show that developing countries that did not adopt green practices on logistic performance pose negative effects in terms of air pollution, climate change, and global warming. Thus, the efforts to reduce environmental degradation must be comprehensive enough and the priority of environmental policies should be in the first place, targeting logistic performance. In other words, performance measure of logistic should also take into account its contribution to environmental quality.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42578774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, microalgae have recognized as a promising biofuel feedstock’s due to the several unique characteristics includes high productivity, no competition for arable land, fresh water and high CO2 sequestration efficiency. High caloric value, low density and low viscosity make it promising source of renewable energy. They also serve the dual purpose of biofuel production along with the production of potentially valuable biomass, which could be utilize for phyco-remediation, food, animal feeds, fertilizers, drugs etc. In spite of huge opportunity, only few algae species were investigated till date. This review paper presents the brief view on the potential of microalgae for biofuel feedstock, different culturing system, algal conversion technology.

This article attempts to take the first steps in looking for the roots of environmental sustainability starting from the traditional wisdom synthesized in proverbs, focusing on the sustainable environmental management. For this purpose, the universal and international principles of environmental law, which are interconnected to the concepts of environmental management (responsibility for protecting the environment) and scientific management in general (functions of the management, decision theory) are used as the backbone of a taxonomic approach. The concept of managerial responsibility takes in ecology the form of individual, group and collective responsibility for the decisions and actions related to the protection of the environment, and also the form of social responsibility. This study continues previous researches of the authors, opening the way to other trans- and interdisciplinary studies. Its main limitation (to Romanian proverbs) gives a possible direction for further research.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47463444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2020 only, the number of publications indexed in the Web of Science (WoS) having the keywords “sustainability” or “sustainable development” in the topic was higher than 42,000. Facing this flood of literature, the present work aims to ease the effort of locating relevant studies about the applications of Agent-based Modeling and Simulation (ABMS) in the research of environmental sustainability. This goal is accomplished by: (a) providing a comprehensive bibliography of recent relevant articles on this topic, (b) identifying the most popular domains of application of ABMS in this field, and (c) building a list of the available simulation tools. We found that most of the selected studies (52%) are designed for management related acticities (decision support, policy making etc.), the application domain addressed by the largest number of articles (27%) is agriculture and related activities (pastoralism, hunting, fishery, and forestry), and the most popular simulation platform is NetLogo (15%).","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42498299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For tracking the evolution of body dam seepage, 12 piezometers and a drainage pipe with discharge in the downstream connection channel of the bottom outlet are used. The paper presents the characteristic elements of the theoretical infiltration curve in the dam It also shows the hydro isohypses for the dam drawn with SURFER program, using the maximum hydrostatic levels in the piezometers measured in the year 2019. The distribution of the hydro isohypses across the dam is strongly influenced by the location of the piezometers and the other point of measuring the hydraulic head. The pattern circulation of the infiltration water inside the dam body could be studied with increased accuracy, if the dam had been equipped with several piezometers. Even in these conditions, it is clearly observed that the regime of infiltrations through the dam body is similar to the theoretical way of behavior.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44580461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The direct consequence of this warming is an increase in extreme weather events and hence in climate risks. The monitoring and assessing precipitation, identifying the physical laws governing its course in order to be able to estimate and forecast it in the future is therefore of great interest nowadays. Using geostatistical spatial analysis methods, this paper aims at identifying the correlations between longitude and precipitation (due to the specificity of the European climate, given by the major influence of the western circulation) and then an estimation - using linear regression equations - of precipitation amounts depending on longitude. Two variables were calculated for the statistical analysis: the proportion of the mean number of days with precipitation ≥ 10 mm of the multiannual mean of precipitation days (≥0,1 mm) and the precipitation ratio between the mean precipitation quantities in summer, compared to those in winter (hereinafter referred to as summer/winter precipitation ratio). The geostatistical analysis carried out on a sample of 40 weather stations aligned from west-south-west to east-north-east argues the existence of a strong correlation between longitude and the multiannual mean of days with precipitation ≥10 mm and between longitude and the summer/winter precipitation ratio.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43234654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Old stands are characterized by their long life, large heights and diameters and by their help in conserving biodiversity. The surfaces occupied by old stands have decreased lately because of their wood mass high value which leads to exploitation. This is furthermore coupled with climate changes, urbanization and human influences. These stands occupy a surface of 128.500 ha in the forests from Dobrogea’s Plateau, where broad-leaved species are preponderant (Quercus sp., Fraxinus ornus, Tilia tomentosa, Acer sp.). As such, the present paper intends to characterize the oldest stands from Dobrogea’s Plateau with the help of forest management plans realized during 1993-2007. The main characteristics analyzed in this study for stands older than 120 years were: location, surface, height, diameter, structure, forest type, soil type, altitude, exposition, slope and consistency. Stand older than 100 years occupy only 4% of the total surface and are composed of linden, brown oak and pedunculate oak which grow and develop on common luvisols.","PeriodicalId":42850,"journal":{"name":"Present Environment and Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45803507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
