The Tohoku earthquake, which occurred on March 11, 2011, caused water-supply outages to 2.2 million households in 187 cities and towns. This earthquake impacted on natural and social events, adversely affecting the water-supply system. For instance, there were long-term disruptions of regional water supplies, long-term electric power outages, extensive liquefaction damage, and damage caused by the tsunami. These multiple factors made the damage pattern complex, and water-supply restoration was delayed even though seismic ground motion was moderate. This study attempts to elucidate the factors that caused water-supply restoration to be delayed following the earthquake and to measure the earthquake impact on water-supply outages in terms of restoration time and the households affected by the water-supply outage. As a result, the long restoration time for the water supply following the Tohoku earthquake could be explained by a combination of factors, including restoration time for electric power and regional water supplies and pipeline repair in liquefaction areas, in addition to time for pipeline repair following past earthquakes. Pipeline repair required twice the time compared to past earthquakes.

Purpose. The purpose of the article is an identifying the impact of regional water management dependence on economic growth in the region. Methodology / approach. The subject of the study is theoretical and methodological basics of a new scientific paradigm for regulation the development of the regional socio-economic systems under the conditions of limited water resources. The study used traditional and special research methods, including: historical and logical – to analyze the evolution of regional socio-economic systems under conditions of limited water resources; abstractions and analogies – to reveal the essence of water-efficient regional socio-economic systems in the modern processes of regionalization and globalization; theoretical generalization, analysis and synthesis – to specify the categorical apparatus; statistical analysis to assess the level of needs of regional socio-economic systems in water resources and create an index of regional water management dependence; method of correlation analysis (biserial correlation, using a point biserial Pearson’s correlation coefficient). Results. The main idea of the paper is to study the issues of development of regional socio-economic systems under the conditions of limited water resources. Considering this, the paper is aimed at studying the impact of regional water management dependence on economic growth in the region. The tasks for development of regional socio-economic systems on the basis of water efficiency are defined, as well as the concept “water-efficient regional socio-economic system” is defined. The study presents a hypothesis about the need to change the paradigm of regulation of regional development on the basis of water use efficiency and regional water management dependence. In order to trade effectively with the main crops, it is necessary to determine whether there are sufficient water supplies in a given country and its regions. For this purpose, the authors proposes to use own indicator, such as the index of regional water management dependence. Thе characteristic of water management dependence is given, from regions where only up to half of the water supply of the territory is used, and to regions where more than 100 % of the water supply of the territory is used. The research has updated that the expansion of knowledge and understanding of the specifics of the water sector can solve significant problems. It is proved that the economic growth of the Ukrainian economy due to the agricultural sector has its limits and is limited by the water management dependence of the territories, ie the limitation of certain territories of the regions of Ukraine in terms of water resources. The next effective economic growth is possible only through the implementation of water-efficient technologies and intensification of water-efficient activities in the region. Originality / scientific novelty. The study for the first time defines the concept of water-efficient regional socio-economic system, so it is a socio-economic system that provides for the restoration of water resources in the region, reducing the water intensity of gross regional product (GRP) and approaching European norms and proposes the classification of regions according to the index of regional water management dependence on the basis of its threshold values. A scientific and methodological approach to assessing the level of needs of regional socio-economic systems in water resources has been improved, based on the application of the index of regional water management dependence, which is proposed to calculate the ratio of total fresh water use in the region to the volume of available river runoff in the region (parts of the water potential). The classification of regional socio-economic systems according to the level of water supply has been improved, which is based on the definition of threshold values of the index of regional water management dependence. The methodological bases for assessing the impact of the spatial economy on regional development under conditions of limited water resources have been improved, which differ in substantiating the dependence of the level of development of regions on the available water potential of the territory. Practical value / implications. The results of the study allow a more comprehensive approach to the study of the problem of using water resources in Ukraine in the context of their limitation. The results of the study showed that the economic complex in most regions is water-intensive and unbalanced, as well as does not provide restoration of water resources by environmental parameters and requires the implementation of infrastructure schemes for redistribution of water resources between regions for economic activity. The results are recommended for consideration by local governments and regional administration for the development and implementation of “Regional programs for the development of water management in the region” and for the development of “Strategies for regional development until 2025–2027”.

Abstract Introduction. Diarrhoeal disease remains a leading cause of mortality and morbidity worldwide. Cholera alone is estimated to cause 95,000 deaths per year, most of which occur in endemic settings with inadequate water access. Whilst a global strategy to eliminate cholera by 2030 calls for investment in improved drinking water services, there is limited rigorous evidence for the impact of improved water supply on endemic cholera transmission in low-income urban settings. Our protocol is designed to deliver a pragmatic health impact evaluation of a large-scale water supply intervention in Uvira (Democratic Republic of the Congo), a cholera transmission hotspot. Methods/Design.A stepped-wedge cluster randomised trial (SW-CRT) was designed to evaluate the impact of a large-scale drinking water supply intervention on cholera incidence among the 280,000 inhabitants of Uvira. The city was divided into 16 clusters, where new community and household taps will be installed following a randomised sequence over a transition period of up to 8 weeks in each cluster. The primary trial outcomes are the monthly incidence of “confirmed” cholera cases (patients testing positive by rapid detection kit) and of “suspected” cholera cases (patients admitted to the cholera treatment centre). Concurrent process and economic evaluations will provide further information on the context, costs and efficiency of the intervention. Discussion.In this protocol, we describe a pragmatic approach to conducting rigorous research to assess the impacts of a complex water supply intervention on severe diarrhoeal disease and cholera in an unstable, low-resource setting representative of cholera-affected areas. In particular, we discuss a series of pre-identified risks and linked mitigation strategies as well as the value of combining different data collection methods and preparation of multiple analysis scenarios to account for possible deviations from the protocol. The study described here has the potential to provide robust evidence to support more effective cholera control in challenging, high-burden settings. Trial registration. This trial is registered on clinicaltrials.gov (NCT02928341, 10th October 2016, https://clinicaltrials.gov/ct2/show/NCT02928341) and has received ethics approval from the London School of Hygiene and Tropical Medicine (8913, 10603) and from the Ethics Committee from the School of Public Health, University of Kinshasa, Democratic Republic of the Congo (ESP/CE/088/2015).

Multi-source, combined water supply models play an increasingly important role in solving regional water supply problems. At present, in the area of regional water supply, models are mainly used to study the problem of overall water guarantee rate, and do not take into account the impact of the uncertainty of multi-source water supplies on water supply risk. There is also a lack of research on how changes in multi-source water supplies affect sub-region and sub-user water guarantee rates. To address this knowledge gap, the encounter probability of different frequencies and a refined water resources allocation model of multi-source supplies were used. Using Tianjin as an example, this paper studies the quantitative relationship between the uncertainty of multi-source water inflows and the regional guarantee rate of water use. The objectives of the study are to analyze the changing trend of the water shortage rate and the main body of water supply in each region, and to quantitatively describe the influence of the variation of multi-source water supply on the main body of water supply for users. The results show that under the same requirement of guarantee rate for water use, as the number of water diversion sources increase, the probability of water supply meeting the water use rate increases significantly, and the risk to water supplies decreases. At the same time, suburban areas have a low dependence on external water supplies, while the change in the quantity of external water sources has a great impact on the water supply of the Zhongxinchengqu and Binhaixiqnu areas. The distribution and main body of water supply will change for different water users. Therefore, it is important to ensure a stable supply of external water for maintaining the guarantee rate of regional water use.

Drinking water supply and sewerage system designing and reconstruction projects are being extensively conducted in Azerbaijan Republic. During implementation of such projects, collecting large amount of information about the area and detailed investigations are crucial. Joint use of the aerospace monitoring and GIS play an essential role for the studies of the impact of environmental factors, development of the analytical information systems and others, while achieving the reliable performance of the existing and designed major water supply pipelines, as well as construction and exploitation of the technical installations. With our participation the GIS has been created in “Azersu” OJSC that includes systematic database of the drinking water supply and sewerage system, and rain water networks to carry out necessary geo information analysis. GIScreated based on “Microstation” platform and aerospace data. <br><br> Should be mentioned that, in the country, specifically in large cities (i.e. Baku, Ganja, Sumqait, etc.,) drinking water supply pipelines cross regions with different physico-geographical conditions, geo-morphological compositions and seismotectonics.Mains water supply lines in many accidents occur during the operation, it also creates problems with drinking water consumers. In some cases the damage is caused by large-scale accidents. Long-term experience gives reason to say that the elimination of the consequences of accidents is a major cost. Therefore, to avoid such events and to prevent their exploitation and geodetic monitoring system to improve the rules on key issues. Therefore, constant control of the plan-height positioning, geodetic measurements for the detailed examination of the dynamics, repetition of the geodetic measurements for certain time intervals, or in other words regular monitoring is very important. During geodetic monitoring using the GIS has special significance. Given that, collecting geodetic monitoring measurements of the main pipelines on the same coordinate system and processing these data on a single GIS system allows the implementation of overall assessment of plan-height state of major water supply pipeline network facilities and the study of the impact of water supply network on environment and alternatively, the impact of natural processes on major pipeline.

The Impact

Advances in technology for in vitro propagation and genetic transformation have accelerated the development of genetically engineered trees during the past 15 years. At least 33 species of transformed forest trees have been successfully regenerated to date. Targeted traits include herbicide tolerance, pest resistance, abiotic stress tolerance, modified fiber quality and quantity, and altered growth and reproductive development. Commercial potential has been demonstrated in the field for a few traits, in particular herbicide tolerance, insect resistance, and altered lignin content. Now that commercial implementation is feasible, at least for the few genotypes that can be efficiently transformed and propagated, environmental concerns have become the main obstacle to public acceptance and regulatory approval. Ecological risks associated with commercial release range from transgene escape and introgression into wild gene pools to the impact of transgene products on other organisms and ecosystem processes. Evaluation of those risks is confounded by the long life span of trees, and by limitations of extrapolating results from small-scale studies to larger-scale plantations. Issues that are central to safe deployment can only be addressed by permitting medium- to large-scale release of transgenic trees over a full rotation. Current regulations restricting field releases of all transgenes in both time and space need to be replaced with regulations that recognize different levels of risk (as determined by the origin of the transgene, its impact on reproductive fitness, and nontarget impacts) and assign a commensurate level of confinement. The next step in determining acceptability of transgene technology for forest tree improvement is the unconfined release of constructs that pose little risk in terms of gene escape and nontarget impacts, such as lignin-altered poplar or pine, to permit evaluation of ecological risks and environmental or agronomic benefits at relevant scales.

The Impact

Introduction. Climate change leads to an increase the number of wildfires and fires in settlements, with 74 % of the country's population living in urban settlements and 26 % in rural settlements. The readiness of localities for the fire season is determined by regulatory documents that do not assess the sufficiency of measures taken by local governments to prepare territories for the fire season, and, accordingly, do not provide protection of localities from the fires. At the same time, there is no scientific and methodological approach for determining the necessary and sufficient number of fire-fighting constructions and assessing the stability of their structure to protect settlements from the effects of mass or large-scale fires. The purpose of the study. The purpose of the study is to ensure the protection of settlements from the impact of mass or large-scale fires. Research methods. To obtain the results, general scientific and special methods of scientific knowledge were used: analysis, synthesis, generalization. They were based on the provisions of the theory of systems, theory of information. The results of the study. The forces and means that can be used to extinguish fires in localities are evaluated, and the main methods used to justify the elements of the fire-fighting water supply system in localities are considered and summarized. Conclusion. There is a contradiction between the need to ensure the protection of settlements from the impact of mass or large-scale fires and the lack of scientific and methodological approach of justification of corresponding set of means and their management. The results of the study are the basis for the development of a scientific and methodological approach to assessing and justifying the forces and means to ensure the protection of settlements from the impact of mass or large-scale fires and the safety of their activities.

Abstract Introduction Preparations of health systems to accommodate large number of severely ill COVID-19 patients in March/April 2020 has a significant impact on nuclear medicine departments. Materials and Methods A web-based questionnaire was designed to differentiate the impact of the pandemic on inpatient and outpatient nuclear medicine operations and on public versus private health systems, respectively. Questions were addressing the following issues: impact on nuclear medicine diagnostics and therapy, use of recommendations, personal protective equipment, and organizational adaptations. The survey was available for 6 days and closed on April 20, 2020. Results 113 complete responses were recorded. Nearly all participants (97 %) report a decline of nuclear medicine diagnostic procedures. The mean reduction in the last three weeks for PET/CT, scintigraphies of bone, myocardium, lung thyroid, sentinel lymph-node are –14.4 %, –47.2 %, –47.5 %, –40.7 %, –58.4 %, and –25.2 % respectively. Furthermore, 76 % of the participants report a reduction in therapies especially for benign thyroid disease (-41.8 %) and radiosynoviorthesis (–53.8 %) while tumor therapies remained mainly stable. 48 % of the participants report a shortage of personal protective equipment. Conclusions Nuclear medicine services are notably reduced 3 weeks after the SARS-CoV-2 pandemic reached Germany, Austria and Switzerland on a large scale. We must be aware that the current crisis will also have a significant economic impact on the healthcare system. As the survey cannot adapt to daily dynamic changes in priorities, it serves as a first snapshot requiring follow-up studies and comparisons with other countries and regions.
