Sustainable development is now a key factor in the global economy. Sustainable development is a process that leads to the satisfaction of the current needs of people and at the same time goes towards further development without destroying and limiting the possibilities of meeting the needs of future generations. Therefore, joint efforts should be made as soon as possible to build a sustainable and safe future for all people and the planet as a whole. Therefore, it is important to promote and support sustainable development by managing natural resources and ecosystems and the entire environment including people. The presented research was done on-site in African and European countries (Egypt, Ethiopia, Guinea, Turkey, and Poland) to determine their level of sustainable development. The level of sustainable development was determined by selected indicators from the Human Development Index. The level of sustainable development was determined by selected indicators from the Human Development Index. In this study, the authors used basic methods of social and economic research as follows: (1) market observation, (2) primary research on-site and (3) secondary research and the use of statistical analysis (Pearson Correlation). These methods were used to define the social and scientific problems and identify factors that affected a country's sustainable development. The main scientific problem, addressed by the study was undertaken in order to help facilitate a outcome on the energy, food and agricultural sectors connected with climate change and environmental law. It was found that there is an extremely strong positive correlation (from 0.8 to 1.0), and a very strong negative correlation (from -0.8 to -1.0) between the levels of a country’s age share, CO2 emissions, renewable energy consumption, and natural resources depletion.

Although the concept of “sustainability” is attributed to Dr. Gro Harlem Brundtland, the principle of inter-generational equity substantiating it is older, at least in the Romanian tradition. 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.

Logistic performance has been improved tremendously in many parts of the world. 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.

Global warming, depleting energy reserve and raising demand have created a upsurge for alternative and environmentally friendly renewable energy sources. 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. In addition, hurdles in commercialization of algal based biofuel technology and strategies were also discussed.

In the context of the alarming news about climate changes, resource depletion, ecological disasters, and demographic trends, the interest of the researchers and the scientific literature on topics related to sustainability grew exponentially in the past two decades. 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%).

The general warming trend of the planet cannot be denied (the average global air temperature has increased by approx. 0.85°C between 1880-2012 (IPCC, 2013). 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.

The dam of the reservoir Cuibul Vulturilor, located on the Tutova river is an inhomogeneous earth dam with a maximum height of 15.0 m, with a clayey central core and lateral prisms made of clayey-dusty sands. 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.

Longevity in life span of city dwellers depends upon the quality of ambient air, which is often compromised due to urbanization. In this context, since independence, Bengaluru has rampantly grown with elevated air and automobile pollution levels. Ambient Carbon Monoxide [CO], which is considered to be the most dangerous criteria air pollutant, however has insufficient research/literature for the city of Bengaluru. To plug this gap, the pre-sent study engages a detailed examination for Temporal and Spatial Map-ping variation of Ambient ‘CO’ concentration in different wards of Bengaluru using calibrated Digital ‘CO’ sensor. The methodology involved primarily an intensive literature review followed by reconnaissance survey for fixation of monitoring stations about each ‘ward’. Further at these observatories, extensive primary data collection was ensued at periodic and regular intervals. The objective serves to delineate the most critical and non-critical places in Bengaluru to incorporate remedial measures. Startling 400+ violations with potential of triggering congestive heart failure, impaired performance in time discrimination, shortened time to angina response and vigilance decrement were observed. Sustainability measures conclude the study.

This paper explores the differences between two different types of potential accessibility models applied to the urban system of Romania, using demographic data from 2015. The first model is based on a classical formalization of the potential accessibility function, while the second one focuses on the introduction of variable parameters in the model’s equation. When mapping the results, one will found that the models we investigated respond to different needs and visions in spatial planning. The alternative formalization provides a frame for a more in-depth analysis of the transportation endowment, at regional scale, together with an assessment of the urban systems hierarchy. The study highlights the fragility of the local urban systems gravitating around small cities, placed in precarious accessibility situations. The results can be used for a better assessment of the policy priorities, both from the perspective of spatial planning and sustainable development.
