Global warming caused by excessive consumption of fossil fuels and carbondioxide emissions is becoming the most important environmental issue in theworld. Tourism industry causes 5% of total carbon dioxide and 14% of totalgreen house of the world. Energy consumption in tourism is in direct relationwith tourists behaviors. To succeed in changing unsustainable behavior andreinforce sustainable behavior should be aware of the factors affecting it. Thisstudy explores the factors affecting the tourists’ intentions to conduct lowcarbonbehaviors from a Protection Motivation theory perspective. Populationof the study consists of Tehran citizens of district 1, which are selected by multiStage Cluster Sampling. A questionnaire was used to collecte data. Foranalyzing collected data, structural equation modeling was used. Findings showthat variables of tourists “Perceived vulnerability”, “Perceived responseefficacy” and “Perceives self-efficacy” have the most effect on their low carbonbehavioral intention respectively

Introduction: The purpose of this paper is to analyze the relationship between economic growth, energy consumption and ecological footprint in 27 developing countries and 27 developed countries during the period 1990-2018. Methodology: This paper analyzes the relationship between economic growth, energy consumption, and ecological footprint in 27 selected developing countries and 27 selected developed countries over a period of 1990-2018. The present model was developed according to as Akadiri et al. (2019) and Mohammad et al. (2019), which are in the form of the following three equations: EFPit=α1+α2iEGit+α3iNRECit+α4iRECit+α5iTECit+α6iURBit+α7iFRit+α8iMRit+α9iHCit+εit (1) NRECit=β1+β2iEFPit+β3iEGit+β4iURBit+β5iFDit+εit (2) EGit=γ1+γ2iEFPit+γ3iNRECit+γ4iRECit+γ5iFDit+γ6iTOit+γ7iLit+γ8iKit+γ9iPIit+γ10iHCit+γ11iMRit+γ12iKOFEit+εit (3) The EFP is an ecological footprint index that compares the rate of resource consumption and production of human waste with the rate of resource reproduction and waste disposal by the biosphere, being defined in terms of the amount of land needed to maintain this cycle. EG is described as the economic growth. NREC is the consumption of non-renewable energy and includes energy from combustible non-renewable energy, such as oil, gas, hydrocarbons, coal, and nuclear energy. REC is the consumption of renewable energy. FD is financial development. URB is the growth rate of urbanization. TO is the degree of trade openness. L is the labor force. K is an investment. HC is human capital. FR is the fertility rate. MR is the mortality rate. PI is political instability. TEC is the technology. KOFE is the globalization of the economy. In order to analyze the relationship between the mentioned variables, the Generalized Method of Moments (Sys-GMM) was used. Results and Discussion: The results showed that in both groups of developed and developing countries, economic growth was correlated with energy consumption and ecological footprint index. Nonrenewable energy consumption, urbanization rate, fertility rate and mortality rate in both groups of the country had positive effects and the renewable energy, technological growth rate and human capital had negative effects on ecological footprint. Economic growth had a negative effect on the ecological footprint of developed countries and a positive effect on the ecological footprint of developing countries, which indicates that more developed countries rely on the use of renewable energy. Ecological footprint has a negative effect and economic growth, urbanization rate and financial development had positive effects on energy consumption in both groups of countries. Ecological footprint has had a negative effect on the economic growth of developed countries and a positive effect on the economic growth of developing countries. Renewable and non-renewable energy, financial development, degree of trade openness, physical capital, labor and economic globalization had positive effects and political instability and mortality rates had negative effects on economic growth in both groups. Conclusion: Based on the results of the research, it is suggested that countries, especially developing countries, try to create and use clean energy. High information, proper education, exchange of information with other countries to benefit from the information and advanced goods that are in line with the environment, taxation of producers who use polluting energy and granting tax exemptions and low-interest and long-term loans to producers who use clean energy will reduce the ecological footprint. Given the impact of non-renewable and renewable energy on growth and economic development, the contradiction of the impact of economic growth on the ecological footprint in developed and developing countries indicates that developed countries have adopted an approach based on which renewable energy is used rather than non-renewable energy in the production process. While the use of non-renewable energy sources in developing countries, although leading to economic growth, has led to environmental degradation. Since increasing economic growth is one of the most important economic goals of countries, it is necessary for policymakers to take measures in terms of economic growth, which imposes the least damage to the environment and achieves the goals of sustainable development. In this regard, it is recommended that the developing countries, as well as the developed countries, use renewable and less polluting energy such as solar, wind, and hydropower instead of non-renewable energy.

Abstract Objective & Background: The aims of this study were to investigate the effects of planting methods on riased bed with microirrigation and seed density on grain yeild and energy indicators of bean production. Materials & Methods: In order to compare the effect of planting methods and seed density on bean line of COS-16 (Straight Type), a split plot experiment in randomized complete block design was carried out in Khomein Bean Research Station during 2016 and 2017 with 3 replications. The main plots were flat planting, single row on a ridge, double rows on a ridge and three rows on a ridges. Sub plots were seed consumption of 70, 120 and 170 kg.ha-1. The space between ridges was 75 Cm. Irrigation type was microirrigation (tape irrigation). Results: Experiment results showed that the treatments of two rows on a ridge with seed consumption of 120 kg.ha-1 and single row on a ridge with seed consumption of 70 kg.ha-1 with yields of 2300 and 2225 kg.ha-1, respectively are beter than other methods. The lowest energy intensity with 34 MJ.kg-1 and the high energy ratio with 0.99 were related to these treatments. Energy intensity and energy ratio of conventional method were 53.7 MJ.kg-1 and 0.63 respectively. Conclusion: The treatments of two rows on a ridge with seed consumption of 120 kg.ha-1 and single row on a ridge with seed consumption of 70 kg.ha-1 are recommended and the flat and three rows on a ridge planting methods does not recommended.

Changes the Sea surface temperature and lake can have significant impacts on marine ecosystems and the lives of human societies on the edges of these seas. By trend analyzing the temperature of sea surface temperatures, we can examine the extent of its impact on global climate change. Given the fact that the Caspian Sea is known as the world's largest closed water body, these changes in surface water temperatures can cause great damage to the sensitive and fragile ecosystem of this sea. The purpose of the present research is to analyze the trend of sea surface temperature in the Caspian Sea in order to investigate the effect of this sea on global climate change in order to apply it in management plans to maintain the balance of this valuable water ecosystem. This research was performed using non-parametric statistical methods on 720 cells using network data with a spatial resolution of 0.25 * 0.25 * arcs in a 29-year statistical period. The results of the study showed that the monthly, seasonal and annual monthly water temperature of the Caspian Sea has a significant upward trend, which requires the attention of planners and decision makers in the margins of this sea to maintain ecosystem balance. Considering that the Caspian Sea is a closed system, any appreciable increase in surface water temperature can have adverse effects on aquatic life, water resources, evaporation from the sea level and, consequently, on the level and status of pollution of the sea.

Climate change is the biggest ecological and social challenge of the current century, which is worth sociological investigation. The purpose of this article is to present general perspectives and highlights regarding sociological approaches concerning adaptation to climate change. The study investigated social approaches based on adaptation with perspectives of sociological research on the drivers of climate change and its consequences. The results were classified in the form of sociological approaches in three scales: macro, medium, and micro. The results showed that structural, institutional, and social adaptation measures are three important options for reducing vulnerability and increasing adaptation capacity. In addition, measures associated with adaptation to climate change to reduce present and future vulnerabilities are under three elements; Exposure, Sensitivity, and Adaptive Capacity. Government solutions to correct climate injustices are still unclear from the perspective of social justice, and there are still many questions that require further study.

The article is devoted to a comprehensive analysis of peculiarities of the content types, which can be placed in social media and Ukrainian Internet media, its differences, types of manipulation, and methods of prevention, perception, and distribution of unreliable information, determination of difference between fact and judgment. The article also analyzes the statistics of social media usage in Ukraine and around the world, using Facebook as an example. Various kinds and types of media existing on the Internet and traditional, conducted a survey of the most popular content using the Starch method, it was possible to identify how a person perceives one content that is placed on different media. The relationship between content type and media type is established. The phenomenon of information restriction, arising as a result of modern algorithms embedded in the Internet companies and social media, their positive and negative aspects and why, therefore, we are deprived of a choice among a wide range of other topics, and learning some other points of view was considered. Examining the origin and meaning of the "Information Bubble" term, the authors propose to use a different term, "Membrane of Relevance", which, in their opinion, is more relevant to the essence of the said concept. The authors propose to use a taxonomy method to determine the impact of content on a particular type of media, which will greatly simplify the content analysis process.

Rural regions have a significant role in preservation of environmental values, folklores and tacit knowledge of nations. Herein, the potentials of natural environment mainly the ways by which a rural landscape can be manipulated by applying natural elements is of major consideration. Based on past and current studies, exploring this area of research can clearly delineate some of the ecological aspects of landscape, while it presents the state of equilibrium and sustainability of natural elements in specific climatic conditions of each region. From a Landscape Architecture point of view, the article aims to present part of carried out studies and researches within the cognition of identity of specifications embedded in rural landscapes with a primary focus on aspects of natural environment and therefore, it’s relevant to specific ecological circumstances. Including both national and international case studies, the research methodology rests on the studies of creditable bibliographies penned in the field of rural areas and countryside regions. More, with respect to the significance of “Ecology”, geographical conditions and social customs in the identity and formation of rural landscape, the article has its main concerns on the land manipulation and the role of natural elements in doing so. On the other hand, “neo-naturalism” approaches were taken into account whereas they have caused documentaries, fundamental studies and re-cognition of vernacular patterns in manipulation of rural landscape. Furthermore, such considerations are of more importance in Iranian plateau due to its specific climatic features and unique vernacular methods; there are plenty of outstanding exemplars of sustainable habitations in central parts of the plateau confirming such claim. Accordingly, the study attempts to answer the following questions: What is the rural landscape and what are its features in terms of habitation and environmental values? What is the role of natural environment and geographical space in the articulation of Rural Landscape? What are the lessons taken from tacit knowledge and the manipulation of rural landscape? The studies confirm the important role of tacit environmental knowledge and ecological tendencies of people in benefitting from natural potentials and cultural values in order to shape habitation clusters and manipulate the landscape of any rural region. Consequently, some of the definitions and specifications regarding rural landscape, as well as scholars’ viewpoints of natural environmental capacities, habitation; the geographical space of a village, economy, lifestyle and eventually the cultural aspects of rural landscapes have been presented in this paper. Some case studies from Kharaneq, Maymand and Al-kas have been provided as in order to support the theories and discussions.

In the early 1980s, an alien ctenophore Mnemiopsis leidyi already known as a gelatinous zooplankton was transported (likely via ballast waters) to the Caspian Sea from its introduced or native water of the Black Sea or western Atlantic which caused negative impacts. In this report, distribution of M. Leidyi, planktonic and benthic organisms had been investigated in the Southern Caspian Sea (Iranian waters) in 6 transects consisted of Lisar, Anzali, Sefidroud, Nowshar, Babolsar and Amirabad at 26 stations during 2005 and 2006. As a whole, 1422 samples had been analyzed included 258, 346, 217, 117 and 484 belong to ctenophore, phytoplankton, zooplankton, benthos and physicochemical parameters, respectively. M. leidyi abundance and biomass were fluctuated between 284-2751 ind.m-2 and 16.9- 390/9 g.m-2 respectively in 2005 while maximum abundance and biomass were recorded in autumn and minimum in winter. In 2006, its mean abundance and biomass were 184-2150 ind.m-2 and 9.1- 209/8 g.m-2 respectively. M. leidyi maximum abundance and biomass were noted in summer and its minimum in spring and winter months. Overall, mean M. leidyi abundance and biomass were recorded in 20 m within 1202 ind.m-2 and 139.5 g.m-2 respectively. Maximum size of the ctenophore was recorded as 55 and 60 mm in 2005 to 2006 respectively, while less than 10 mm length frequency consisted 83.16 and 82.88 per cent of total population. Spatial_ temporal distribution of M. leidyi in different regions showed it was more abundant in west and east (714- 4494 ind.m-2) ratio to central parts (13-1519 ind.m-2) of the Southern Caspian Sea. Species composition of zooplankton had shown the negatively impacts of M. leidyi invasion in the period of sampling as the only 17 holozooplankton were determined with Rotatoria (7 species), Copepoda (4 species), Ciliophora (4 species) and cladocera (1 species). Zooplankton maximum abundance and biomass were recorded in February (3039742901 ind.m-3 and 372.1575.4 mg.m-3) respectively and its minimum were in July (12211601 ind.m-3 and 6.9 7.7 mg.m-3) respectively which was belonged to Rotatoria (76%) and Copepoda (10%). In this study, 21 species of benthic fauna were deter minted belong to Pseudocumidae (5 species), Gamaridae (4 species) Amphartidae (3 species), Oligochaeta, Balanidae, Xantidae, Nereidae, Scarbicularidae, Carididae, Mytilidae, Herpobdellidae and Chironomidae (each 1 species). Oligocheata was recorded with maximum abundance (943 2502 ind.m-2) and Bivalve consisted of higher biomass (68.7162.5 g.m-2). From five phyla of phytoplankton, 172 species were determined of Chrysophyta (74 species), Cyanophyta (32 species), Chlorophyta (32 species), Pyrrophyta (24 species) and Euglenophyta (13 species), in which Chrysophyta and Pyrrophyta were noted as main groups with their maximum abundance (up to 65%) and biomass (93%). Maximum water temperature was recorded in August with 29.52.5 ֯C and minimum in February by 9.31.3 ֯C. Mean value of salinity was 12.010.90 ppt, secchi disk ranged between 0.2 to 7 m and oxygen demand varied from 5.95 to 10.54 mg. l-1). Moreover, silicate concentration was recorded between 200 to 300μg.L-1, Phosphate measured from 31-47 μg.L-1, Ammonia varied in 10-29 μg.L-1, Nitrite (0.6- 1.7 μg.L-1), Nitrate (0.06-4.20 μg.L-1, which mainly accumulated in coastal waters of the southern Caspian Sea.

With the global warming and introduction of serious issues and concerns realting to the escalation of greenhouse gases, which directly affects the lives of flora and fauna, and the role of polluting gases such as carbon dioxide, man has strived to deal with this problem using new technologies. One of those technologies is to capture and store carbon dioxide under the seabed. Nevertheless, legal rules governing the different aspects of this process are not clear. Although, 1982 LOSC rules, 1975 London Convention and its additional protocol (2006) and even some European Union directives that contain provisions in this area are significant, but still some existing challenges, including the environmental consequences resulting from the use of this technology requires serious attention in the international practice and relevant legal documents. In this paper we will briefly examine the existing legal capacities and some of the challenges relating to this technology.

Detecting trend and stationarity in hydrological time series may help us to understand the possible links between hydrological processes and global climate changes. The main purpose of this study is to find any possible relations between streamflow and temperature trend and climate changes. Trend analysis with Mann-Kendall and seasonal Kendall test showed that there is no trend in annual mean discharges but monthly flow series exhibit significant downward trend in specific months. Stationarity tested with five methods which are ADF test, Dickey-Fuller test with GLS detrending (DFGLS), KPSS test, Phillips and Perron test and Elliot, Rothenberg and Stock test. Most annual and monthly discharge series appear to be significantly stationary. All methods for 10 days and daily flow series cannot pass stationarity test even at 1% level. Nonstationarity on daily and 10days timescale might be the result of climate changes. The results imply that because of high dependence of rivers located in the west of UrmiaLake on snow melt water, and temperature, climate change is the main cause of downward trend of ShaharchiRiver and Urmia lake depletion.
