Abstract An increase in the global mean sea is predicted during the 21st century as a consequence of global average temperature projections. In addition, changes in the strength of atmospheric cyclonic storms may alter the development of storm surges, exacerbating the risks to coastal communities. Based on the fact that the interest and range of papers are growing on this topic, this study aims to present the global scientific production status of studies that have correlated climate change and the impact of storm surges on the coastal zone leading to erosion and flooding (inundation) via a bibliometric analysis. We analyzed 429 papers published in journals between 1991 and February 2021 from the Scopus database. Through the VOSviewer and Bibliometrix R package, we describe the most relevant countries, affiliations, journals, authors, and keywords. Our results demonstrate that there has been an exponential growth in the research topic, and that authors from the United States and the United Kingdom are the most prolific. Among the 1454 authors found, 10 researchers published at least 5 papers on the topic and obtained at least 453 citations in the period. The most represented journals were the Journal of Coastal Research, Climatic Change, and Natural Hazards. We also found, and discuss, the lack of standardization in the choice of keywords, of which climate change, storm surge, and sea level rise are the most frequent. Finally, we have written a guide to facilitate the authors' bibliographic review.

Clavulanic acid (CA), a potent inhibitor of the β-lactam, ase enzyme, is frequently co-formulated with a broad spectrum of antibiotics to treat infections caused by β-lactamase-producing pathogens. In order to evaluate the impact and the progress of CA studies in the last four decades, a bibliometric analysis of the global scientific production of CA was carried out. A total of 39,758 records in the field of CA were indexed in the Scopus database for a 43-year period of study (1975–2017). The results indicated that CA studies have grown, showing three phases (1975–1999, 2000–2003 and 2004–2017) based on records of publications; the results showed a sigmoidal profile. Medicine was the main subject area for CA studies, whereas biochemistry, genetics and molecular biology were areas of research for CA production by Streptomyces clavuligerus (S. clavuligerus). Nevertheless, chemical engineering (as a subject area) had the highest increase in the percentage of publications related to CA production by S. clavuligerus. The United States, France, the United Kingdom, Spain and Brazil were the leading countries in the scientific production of studies on both CA and CA related to S. clavuligerus. This analysis allowed the identification of the area of knowledge with the highest impact on CA studies, the top researchers and their geographic distribution, and also helped to highlight the existence of antibiotic-resistant bacteria as an emergent area in CA research.

Although vaccination is carried out worldwide, the vaccination rate varies greatly. As of 24 May 2021, in some countries, the proportion of the population fully vaccinated against COVID-19 has exceeded 50%, but in many countries, this proportion is still very low, less than 1%. This article aims to explore the impact of vaccination on the spread of the COVID-19 pandemic. As the herd immunity of almost all countries in the world has not been reached, several countries were selected as sample cases by employing the following criteria: more than 60 vaccine doses per 100 people and a population of more than one million people. In the end, a total of eight countries/regions were selected, including Israel, the UAE, Chile, the United Kingdom, the United States, Hungary, and Qatar. The results find that vaccination has a major impact on reducing infection rates in all countries. However, the infection rate after vaccination showed two trends. One is an inverted U-shaped trend, and the other is an L-shaped trend. For those countries with an inverted U-shaped trend, the infection rate begins to decline when the vaccination rate reaches 1.46–50.91 doses per 100 people.

This study explores the impact of environmental policies and human development on the CO2 emissions for the period of 1995–2015 in the Group of Seven and BRICS economies in the long run through panel cointegration and causality tests. The causality analysis revealed a bilateral causality between environmental stringency policies and CO2 emissions for Germany, Japan, the United Kingdom, and the United States of America, and a unilateral causality from CO2 emissions to the environmental stringency policies for Canada, China, and France. On the other hand, the analysis showed a bilateral causality between human development and CO2 emissions for Germany, Japan, the United Kingdom, and the United States of America, and unilateral causality from CO2 emissions to human development in Brazil, Canada, China, and France. Furthermore, the cointegration analysis indicated that both environmental stringency policies and human development had a decreasing impact on the CO2 emissions.

Global warming is the increase in the average temperature of the Earth’s surface. According to the IPCC (Intergovernmental Panel on Climate Change) average temperature of the Earth’s surface was global warming is the increase in the average temperature of the 0.74 ± 0.18 0C (1.33 ± 0.32 F) over the last hundred years. The impact of rising temperatures is the climate change effect on agricultural production. If the community does not craft made adaptation to global warming will have an impact on food security. This research aims to know the society’s adaptation to food security as a result of global warming and to know the influence of global warming on food security. The research was carried out based on survey methods. The influence of global warming on food security is identified with a share of household food expenditure and the identification of rainfall. Sampling was done by random sampling. The Data used are the primary and secondary data. Primary Data obtained through structured interviews and depth interview using a questionnaire while the secondary data retrieved from publication data of the Central Bureau Statistics B(BPS), Department of Agriculture and Climatology Meteorology and Geophysics (BMKG). The expected results of the study is to know variations of food security due to global warming in Kulon Progo Regency. Comprehensive knowledge through community participation and related Government increased food security that is used as the basis for drafting the model society’s adaptation to the impacts of global warming.

The article investigates the impact of Great Britain on the evolution of colonialism in the late ХІХ and early ХХ centuries. It is analyzed the sources and scientific literature on the policy of the United Kingdom in the colonial question in the late ХІХ – early ХХ century. The reasons, course and consequences of the intensification of British policy in the colonial problem are described. The process of formation and implementation of London’s initiatives in the colonial question during the period under study is studied. It is considered the position of Great Britain on the transformation of the colonial system in the late XIX – early XX centuries. The resettlement activity of the British and the peculiarities of their mentality, based on the idea of racial superiority and the new national messianism, led to the formation of developed resettlement colonies. The war for the independence of the North American colonies led to the formation of a new state on their territory, and the rest of the “white” colonies of Great Britain had at the turn of the XIX-XX centuries had to build a new policy of relations, taking into account the influence of the United States on them, and the general decline of economic and military-strategic influence of Britain in the world, and the militarization of other leading countries. As a result, a commonwealth is formed instead of an empire. With regard to other dependent territories, there is also a change in policy towards the liberalization of colonial rule and concessions to local elites. In the late ХІХ – early ХІХ centuries the newly industrialized powers (Germany, Italy, and Japan) sought to seize the colonies to reaffirm their new status in the world, the great colonial powers of the past (Spain, Portugal, and the Netherlands) sought to retain what remained to preserve their international prestige, and Russia sought to expand. The largest colonial empires, Great Britain and France, were interested in maintaining the status quo. In the colonial policy of the United Kingdom, it is possible to trace a certain line related to attempts to preserve the situation in their remote possessions and not to get involved in conflicts and costly measures where this can be avoided. In this sense, the British government showed some flexibility and foresight – the relative weakening of the military and economic power of the empire due to the emergence of new states, as well as the achievement of certain self-sufficiency, made it necessary to reconsider traditional foreign policy. Colonies are increasingly no longer seen as personal acquisitions of states, and policy toward these territories is increasingly seen as a common deal of the international community and even its moral duty. The key role here was to be played by Great Britain, which was one of the first to form the foundations of a “neocolonial” system that presupposes a solidarity policy of Western countries towards the rest of the world under the auspices of London. Colonial system in the late ХІХ – early ХІХ century underwent a major transformation, which was associated with a set of factors, the main of which were – the emergence of new industrial powers on the world stage, the internal evolution of the British Empire, changes in world trade, the emergence of new weapons, general growth of national and religious identity and related with this contradiction. The fact that the First World War did not solve many problems, such as Japanese expansionism or British marinism, and caused new ones, primarily such as the Bolshevik coup in Russia and the coming to power of the National Socialists in Germany, the implementation of the above trends stretched to later moments.

In this paper, the author analyzes the organization of fl ood risk insurance, the risk which signifi cantly deteriorates due to climate change in Germany, the United Kingdom and Serbia. Th e author used selected studies and works, national legislation, insurance conditions and materials of specialized organizations. Climate change signifi cantly aff ects the frequency and severity of the harmful consequences of fl ood risks, which, due to their catastrophic consequences and territorial exposure, require more effi cient prevention measures and the design of their insurance. Floods are increasingly occurring as a result of heavy rainfall and high winds that simultaneously enhance their harmful potential. Th erefore, insurers cannot ignore the impact of climate change on the conditions for taking risks, determining the insurance premium, excesses and all other aspects related to these risks. From the point of view of risk assessment and selection techniques, the principle of fl ood insurability will certainly be applied in the future. Th erefore, refraining insurers from insuring those risks where the recurrence of fl oods is more frequent than a certain number of years (fi ve or ten years), based on the historical development of claims or classifi cation of zones into the danger class with increased frequency, will certainly pose a problem for policyholders. In Germany, fl ood risk cover is provided similarly to a number of Serbian insurers, ie. as an additional risk to basic property risks. However, the German insurance practice provides an opportunity to insure a number of other natural risks as a supplementary risk in the form of a natural risk package. It should be pointed out that there are also insurers in Serbia, whose policy terms regarding the cover scope more or less coincide with the insurance of named risks in Great Britain. Th ese are insurance conditions that represent an extension of the so-called traditional insurance of named fi re risks, which certainly represents a good step in the direction of modernizing the household insurance conditions in Serbia.

Do negative shocks in origin countries encourage or inhibit international migration? What roles do networks play in modifying out-migration responses? The answers to these questions are not theoretically obvious, and past empirical findings are equivocal. We examine the impact of hurricanes on a quarter century of international migration to the United States. Hurricanes increase migration to the United States, with the effect’s magnitude increasing in the size of prior migrant stocks. We provide new insights into how networks facilitate legal, permanent US immigration in response to origin country shocks, a matter of growing importance as climate change increases natural disaster impacts.

This paper examines the impact that climate change may have on the lodging of oats in the Republic of Ireland and the UK. Through the consideration of a novel lodging model representing the motion of an oat plant due to the interaction of wind and rain and integrating future predictions of wind and rainfall due to climate change, appropriate conclusions have been made. In order to provide meteorological data for the lodging model, wind and rainfall inputs are analysed using 30 years’ time series corresponding to peak lodging months (June and July) from 38 meteorological stations in the United Kingdom and the Irish Republic, which enables the relevant probability density functions (PDFs) to be established. Moreover, climate data for the next six decades in the British Isles produced by UK climate change projections (UKCP18) are analysed, and future wind and rainfall PDFs are obtained. It is observed that the predicted changes likely to occur during the key growing period (June to July) in the next 30 years are in keeping with variations, which can occur due to different husbandry treatments/plant varieties. In addition, the utility of a double exponential function for representing the rainfall probability has been observed with appropriate values for the constants given.

The Chitwan Annapurna Landscape (CHAL) is the central part of the Himalayas and covers all bioclimatic zones with major endemism of flora, unique agro-biodiversity, environmental, cultural and socio-economic importance. Not much is known about temperature and precipitation trends along the different bioclimatic zones nor how changes in these parameters might impact the whole natural process, including biodiversity and ecosystems, in the CHAL. Analysis of daily temperature and precipitation time series data (1970–2019) was carried out in seven bioclimatic zones extending from lowland Terai to the higher Himalayas. The non-parametric Mann-Kendall test was applied to determine the trends, which were quantified by Sen’s slope. Annual and decade interval average temperature, precipitation trends, and lapse rate were analyzed in each bioclimatic zone. In the seven bioclimatic zones, precipitation showed a mixed pattern of decreasing and increasing trends (four bioclimatic zones showed a decreasing and three bioclimatic zones an increasing trend). Precipitation did not show any particular trend at decade intervals but the pattern of rainfall decreases after 2000AD. The average annual temperature at different bioclimatic zones clearly indicates that temperature at higher elevations is increasing significantly more than at lower elevations. In lower tropical bioclimatic zone (LTBZ), upper tropical bioclimatic zone (UTBZ), lower subtropical bioclimatic zone (LSBZ), upper subtropical bioclimatic zone (USBZ), and temperate bioclimatic zone (TBZ), the average temperature increased by 0.022, 0.030, 0.036, 0.042 and 0.051 °C/year, respectively. The decade level temperature scenario revealed that the hottest decade was from 1999–2009 and average decade level increases of temperature at different bioclimatic zones ranges from 0.2 to 0.27 °C /decade. The average temperature and precipitation was found clearly different from one bioclimatic zone to other. This is the first time that bioclimatic zone level precipitation and temperature trends have been analyzed for the CHAL. The rate of additional temperature rise at higher altitudes compared to lower elevations meets the requirements to mitigate climate change in different bioclimatic zones in a different ways. This information would be fundamental to safeguarding vulnerable communities, ecosystem and relevant climate-sensitive sectors from the impact of climate change through formulation of sector-wise climate change adaptation strategies and improving the livelihood of rural communities.
