The Globalization of International Migration? A Conceptual and Data‐Driven Synthesis

AbstractAlthough the globalization of international migration is commonly accepted as a general tendency in contemporary migration patterns (de Haas, Castles, and Miller 2020, 9), the corresponding body of empirical evidence is mixed and fragmented. Our review of global migration patterns over the past half‐century highlights how the theories, expectations, and ultimately findings may vary depending on the specific definitions, vantage points, and measures being used. In this paper, we provide a simpler and integrated account of the globalization of international migration that includes a corresponding empirical template to quantify the relative importance of two processes at work: the intensity and connectivity of international migration. Using recent estimates of country‐to‐country migration flows every five years from 1990–1995 to 2015–2020, our analysis using demographic decomposition and group‐based multitrajectory modeling highlights the dynamic relationship between intensity and connectivity from both the global and country vantage points. Our work in this paper provides a starting point in the form of a much‐needed empirical template, one that is also highly flexible and customizable, for future research on the globalization of international migration to coalesce around and use going forward.

Distinctive and highly variable bird migration system revealed in Eastern Australia.

Our understanding of bird migration is heavily biased toward long-distance movements in the Northern Hemisphere,1,2,3 with only fragmented knowledge from the Southern Hemisphere.4,5 In Australia, while some species migrate,4,6,7,8 the timing and direction of large-scale, multi-species seasonal movements remain critically understudied due to the complexity of movement in this region and a lack of research personnel and infrastructure.7,9 It is still unclear whether there are pronounced and structured mass movements resembling those in the Northern Hemisphere.10,11,12 Here, we analyze data from a latitudinal transect of weather radars spanning the entire coastline of Eastern Australia to determine the magnitude, directions, timing, and variability of bird migration compared to that of Northern Hemisphere migration systems. Bird movements exhibited sequential seasonal peaks along a latitudinal gradient with seasonally contrasting flight directions, confirming that a structured bird migration system exists. Three features were distinct from Northern Hemisphere migrations. First, distinct movements occurred around sunrise with comparable magnitudes to nocturnal migration, likely representing a strong diurnal component to the bird movements. Second, migration intensity averaged 0.06 million birds km-1 in autumn, much lower than Northern Hemisphere migrations.11,12,13 Finally, flight directions were more dispersed, and the timing and amount of migration were highly variable between years compared to Northern Hemisphere migration systems, perhaps in response to variable climate.7 This first quantification of continental-scale movements in Australia revealed a distinctive migration system, and it suggests that much remains to be discovered about the ecological and evolutionary factors shaping animal migrations in the Southern Hemisphere.

Defining and characterizing the phenomenon of river-bottom tearing scour (RBTS): A case study of the Middle Yellow River

River-bottom tearing scour (RBTS) in natural rivers refers to the incipient motion and transport processes of clay blocks formed by fine cohesive sediment after deposition and consolidation in riverbeds. The RBTS phenomenon can lead to significant channel erosion and changes in river planview morphology, and has, thus, attracted the attention of hydrologists and engineers. In the study, a new determination measure (K) for the occurrence of a RBTS event is derived based on the theoretical expression for the critical incipient velocity of the clay block, K=α2(CL+2λ22), which is a combination of the coefficients of the velocity (i.e., α is a local velocity coefficient), lift force (i.e., CL is the lift coefficient), and clay block size (i.e., λ2 is the ratio of block thickness to length). Furthermore, to explain river behavior during a RBTS event, the Fugu, Xiaobeiganliu, and Weihe river reaches in the Middle Yellow River (MYR) were selected as study areas. Analysis of hydrological data from 1950 to 2023 in the examined reaches implies that a single discharge or sediment threshold cannot predict the occurrence of RBTS. The cross-sectional erosion and deposition volume (CEDV) and the migration intensity of the channel thalweg (MI) also were calculated at the section and reach scales for the examined reaches during the RBTS events. It was observed that RBTS typically causes significant channel erosion originating from the most upstream portion of the study reach with CEDV values ranging from 61 to 6034 m2, while MI values during the RBTS events were close to the multi-year average for the study reach. Finally, a flume experiment simulating RBTS was done to discuss and verify the threshold value of K. Field survey and experimental results indicated that RBTS occurs if K > 0.5, thus, providing theoretical support for the prediction and prevention of RBTS.

Electrokinetic Remediation of Cu- and Zn-Contaminated Soft Clay with Electrolytes Situated above Soil Surfaces.

Electrokinetic remediation (EKR) has shown great potential for the remediation of in situ contaminated soils. For heavy metal-contaminated soft clay with high moisture content and low permeability, an electrokinetic remediation method with electrolytes placed above the ground surface is used to avoid issues such as electrolyte leakage and secondary contamination that may arise from directly injecting electrolytes into the soil. In this context, using this novel experimental device, a set of citric acid (CA)-enhanced EKR tests were conducted to investigate the optimal design parameters for Cu- and Zn-contaminated soft clay. The average removal rates of heavy metals Cu and Zn in these tests were in the range of 27.9-85.5% and 63.9-83.5%, respectively. The results indicate that the Zn removal was efficient. This was determined by the migration intensity of the electro-osmotic flow, particularly the volume reduction of the anolyte. The main factors affecting the Cu removal efficiency in sequence were the effective electric potential of the contaminated soft clay and the electrolyte concentration. Designing experimental parameters based on these parameters will help remove Cu and Zn. Moreover, the shear strength of the contaminated soil was improved; however, the degree of improvement was limited. Low-concentration CA can effectively control the contact resistance between the anode and soil, the contact resistance between the cathode and soil, and the soil resistance by increasing the amount of electrolyte and the contact area between the electrolyte and soil.

Drivers of overseas labour migration, migration intensity, and destination choice among farming households in Nepal

ABSTRACT In recent years, overseas labour migration has become a lifeline for many households in Nepal. Using survey data from 465 randomly selected households and 227 overseas labour migrants, this paper examines the factors influencing overseas labour migration and migration intensity in farming households by employing a generalised two-part fractional regression model, and migrants’ destination choice by using the probit model. We find that a higher proportion of educated members in the household, along with household’s credit access, indebtedness, and contacts with manpower agencies significantly increase the likelihood of overseas labour migration and migration intensity in the households, whereas the presence of employed members in the household, larger farms, irrigation access, and higher asset index significantly lower such likelihood. We find a lower likelihood of migration to Malaysia and the Middle East countries among individuals with employed household members and a higher asset index, while those connected to manpower agencies are more likely to choose these countries as destinations. Our findings emphasise the significance of creating and providing decent economic opportunities, including strengthening the agriculture sector, to address the existing surge in overseas labour migration from farming households in Nepal.

The ontology, measurement, and features of temporary internal migration in selected countries of Asia

ABSTRACT Temporary internal migration is an important livelihood strategy but there have been inconsistencies in its conceptualisation and measurement which limit understanding of the phenomenon across diverse geographical contexts. This paper explores the ontological category of temporary internal migration and how it is defined and measured in eight Asian countries. We identify three broad approaches to measurement: Place of enumeration; Multilocality and Administrative measures. Using these data, we undertake comparisons of migration intensity, age profiles, and rural- to-urban flows across countries in our sample. Our findings indicate that temporary migration ranges between 0.3 to 2.9 per cent of the population—likely an underestimate of internal temporary mobility. Applying an average intensity of 1.5 per cent to all Asian countries yields an estimate of 71 million temporary internal migrants in any given year. Analysis of age profiles reveals that temporary internal migration peaks not only at young adult ages, but also at older ages in selected countries, pointing to the importance of consumption-related movements in some settings. The geographical patterns are also diverse with rural-to-urban flows matched by significant rural-to-rural and urban-to-rural flows. The paper concludes with recommendations for advancing both the conceptualisation and measurement of temporary internal migration.

O zrównoważonym rozwoju w warunkach migracji kapitału ludzkiego: nowy program na rzecz zewnętrznych i wewnętrznych przesiedleń ludności

The article examines the relationship between the migration of human capital and the sustainable development of socio-economic systems. The evolutionary role of migration and its dual nature are substantiated. It has been proven that, on the one hand, the influx of migrants creates a burden on social protection systems; on the other hand, developed countries that receive the main migration flows show a fairly high degree of socio-economic sustainability and compete for high-quality human capital. An analysis of the quantitative and qualitative characteristics of human capital migration was carried out. The main reasons for external and internal population movement in the EU countries and Ukraine, the directions of trends, the intensity of migration and emigration in the EU countries are identified. Socio-demographic portraits of migrants from the EU countries and Ukraine were formed before and after the start of a full-scale war in Ukraine. The benefits of losses, risks, opportunities for migration of human capital and sustainable development are identified and compared. The consequences of migration for the implementation of Sustainable development goals of host countries and donor countries are identified.

Effects of stepwise depressurisation rate on methane hydrate dissociation dynamics at pore scale using microfluidic experiments

Methane hydrate, recognized as a potential alternative energy source, faces challenges in achieving efficient production. Stepwise depressurisation has emerged as a viable technique for enhancing productivity, yet optimizing the depressurisation rate remains a complex issue. This study employs pore-scale experiments using microfluidic chips to examine the dissociation characteristics of methane hydrate under varying stepwise depressurisation rates. At a high depressurisation rate of 0.4 MPa/15 min, the dissociation process exhibits a three-stage pattern: stabilisation, rapid dissociation, and slow dissociation. During these stages, the mass transfer limitation in the water phase significantly impedes the dissociation rate. The gas-water migration triggered by depressurisation can mitigate this limitation. As the depressurisation rate is reduced to 0.2 MPa/15 min, the rapid dissociation stage splits into two due to a decrease in gas-water migration intensity. The dissociation rate decreases by 45% compared to the 0.4 MPa/15 min case. This results from an insufficient driving force for dissociation, necessitating another depressurisation step. Further reduction of the depressurisation rate to 0.1 MPa/15 min leads to a less pronounced gas-water migration, which is inadequate to significantly counteract the mass transfer limitation. As a result, the rapid dissociation phase occurring at a depressurisation rate of 0.4 MPa/15 min, which exhibits an average dissociation rate of 0.2%/s, subsequently transitions into a more uniform and slower dissociation stage, where the average rate of dissociation declines to below 0.07%/s. The experimental results offer valuable insights for guiding hydrate exploration strategies during the stepwise depressurisation process by adjusting the depressurisation rate to regulate production.

Determinants of the Tendency for Migration of Nursing Students Living in Rural Areas of Eastern Poland

The economic emigration of young people from rural areas in Poland, and in particular the emigration of young medical personnel, is a relatively little-recognized phenomenon. What distinguishes this study from many works on related topics is that the subject of the study is the tendency or desire to migrate itself, and not the study of the migration motives of people who have already emigrated. The main aim of the research was to identify the migration conditions of young nurses from rural areas. An additional goal was to determine the directions and types of foreign migrations and their impact on the competitiveness and sustainable development of the studied region. The research was conducted in five voivodeships of Eastern Poland among students at state medical universities. The research tool was a survey, the essence of which was to provide data on the purpose of migration of young people, chances of finding a job abroad, and identification of push and pull migration factors. Based on the logistic regression model, a number of factors were identified explaining the tendency to migrate, such as economic factors, gaining professional experience, and prospects. The influence of factors pushing migration should be reduced through state policy tools. The intensity of migration may significantly impact the sustainable development of healthcare in Poland in the near and distant future.

Spatial and Climatic Patterns of Intraregional Migration in the Republic of Sakha (Yakutia)

Abstract This study investigates the impact of the geographical location of uluses (municipal districts) and their climate on intraregional migration in the Republic of Sakha (Yakutia). Six of the most common indices describing the intensity of migration were used for the analysis. Despite strong outflows of population from the north, the disparities between the Arctic uluses and the rest of the Republic were statistically insignificant. Disparities between geographical parts of Yakutia and clusters by temperature were more marked, but they were not observed for all indices. This is due to a very low migration turnover in the south. The study finds that the geographical location of the uluses and their climate had some influence on intraregional migration, but socioeconomic determinants were much more important.

Continental-scale patterns in diel flight timing of high-altitude migratory insects.

Many insects depend on high-altitude, migratory movements during part of their life cycle. The daily timing of these migratory movements is not random, e.g. many insect species show peak migratory flight activity at dawn, noon or dusk. These insects provide essential ecosystem services such as pollination but also contribute to crop damage. Quantifying the diel timing of their migratory flight and its geographical and seasonal variation, are hence key towards effective conservation and pest management. Vertical-looking radars provide continuous and automated measurements of insect migration, but large-scale application has not been possible because of limited availability of suitable devices. Here, we quantify patterns in diel flight periodicity of migratory insects between 50 and 500 m above ground level during March-October 2021 using a network of 17 vertical-looking radars across Europe. Independent of the overall daily migratory movements and location, peak migratory movements occur around noon, during crepuscular evening and occasionally the morning. Relative daily proportions of insect migration intensity and traffic during the diel phases of crepuscular-morning, day, crepuscular-evening and night remain largely equal throughout May-September and across Europe. These findings highlight, extend, and generalize previous regional-scale findings on diel migratory insect movement patterns to the whole of temperate Europe. This article is part of the theme issue 'Towards a toolkit for global insect biodiversity monitoring'.

Diplomasi Indonesia dan Persoalan Migran Asal Indonesia Pasca Konflik Suriah

The repatriation of Indonesian migrants from Syria in April 2023 reminded us to the repatriation wave of Indonesian migrant from Syria after the country was torn by internal conflict since 2011. Indonesian Government has conducted series of diplomatic efforts to ensure the safety of its citizen in Syria. Indonesian Government was decided to stop sending its workers to Syria since 2011. Indonesia also categorized Syria as one of rescticted destinations for its migrant workers since 2015. Then why are there Indonesian migrants in Syria after those restrictions was applied? This fact indicates that there was illegal procedure available that enabled the workers to migrate to Syria amids the restrictions which out of sight of the government monitor. This paper addressed two issues: Indonesian diplomacy as a respon to the conflict in Suriah; and the problems faced by Indonesian Migrant Workers (IMW) because of the conflict in Syria. This paper identified two problems faced by IWM in Syria after the conflict: security threats caused by the conflict that contributes to the occurrence of illegal migration to Syria; and labour issues that wosened by intensity of illegal migration during the conflict.

Forecasting nocturnal bird migration for dynamic aeroconservation: The value of short‐term datasets

Abstract Placing wind turbines within large migration flyways, such as the North Sea basin, can contribute to the decline of vulnerable migratory bird populations by increasing mortality through collisions. Curtailment of wind turbines limited to short periods with intense migration can minimize these negative impacts, and near‐term bird migration forecasts can inform such decisions. Although near‐term forecasts are usually created with long‐term datasets, the pace of environmental alteration due to wind energy calls for the urgent development of conservation measures that rely on existing data, even when it does not have long temporal coverage. Here, we use 5 years of tracking bird radar data collected off the western Dutch coast, weather and phenological variables to develop seasonal near‐term forecasts of low‐altitude nocturnal bird migration over the southern North Sea. Overall, the models explained 71% of the variance and correctly predicted migration intensity above or below a threshold for intense hourly migration in more than 80% of hours in both seasons. However, the percentage of correctly predicted intense migration hours (top 5% of hours with the most intense migration) was low, likely due to the short‐term dataset and their rare occurrence. We, therefore, advise careful consideration of a curtailment threshold to achieve optimal results. Synthesis and applications: Near‐term forecasts of migration fluxes evaluated against measurements can be used to define curtailment thresholds for offshore wind energy. We show that to minimize collision risk for 50% of migrants, if predicted correctly, curtailments should be applied during 18 h in spring and 26 in autumn in the focal year of model assessments, resulting in an estimated annual wind energy loss of 0.12%. Drawing from the Dutch curtailment framework, which pioneered the ‘international first’ offshore curtailment, we argue that using forecasts developed from limited temporal datasets alongside expert insight and data‐driven policies can expedite conservation efforts in a rapidly changing world. This approach is particularly valuable in light of increasing interannual variability in weather conditions.

Thermal conditions in the marine coastal waters as a factor favorable for formation of extra-strong year-classes of Karaginsky pink salmon

Variability of the timing for downstream migration of juvenile pink salmon from the Hailulya River to the adjacent coastal waters of Karaginsky Bay is considered and influence of the coastal water temperature on strength of the year-classes for two generative lines of pink salmon spawning in the Karaginsky Bay is analyzed for 1978–2020. The optimal conditions for the downstream migration in the period after 2002 are determined as the mean weighted per migration intensity water temperature > 5.6 o C (up to 7.8 о С on average with the maximum 9.9 о С in some years) and a stable increasing of the temperature during migration. The factor of food availability for juveniles became less important for formation of the Karaginsky pink salmon year-classes since the late 2000s, in comparison with the temperature. Statistical model is proposed for the year-class strength dependence on the temperature of coastal waters in late June and the parents number (R2 = 0.791). The modeled hindcasts of the pink salmon returns in 2021–2023 were rather satisfactory. Given these new results, the limits of pink salmon escapement to spawning grounds could be reconsidered and fishery management models should be adjusted to modern conditions of unrestricted juvenile feeding to get and rationally exploit super-strong year-classes of this species.

Evaluating the potential of bioacoustics in avian migration research by citizen science and weather radar observations.

The study of nocturnal bird migration brings observational challenges because of reduced visibility and observability of birds at night. Remote sensing tools, especially radars, have long been the preferred choice of scientists to study nocturnal migrations. A major downside of these remote sensing tools is the lack of species-level information. With technological advances in recent decades and with improved accessibility and affordability of acoustic tools, sound recordings have steeply increased in popularity. In Europe, there is no exhaustive qualitative and quantitative evaluation of the content of such acoustic databases and therefore the value for migration science and migration-related applications, such as bird collision hazard assessments, is mostly unknown. In the present work we compared migration schedules estimated from citizen science data with quantitative temporal occurrence of species in four years of acoustic recordings. Furthermore, we contrasted acoustic recordings with citizen science observations and weather radar data from one spring and one autumn season to assess the qualitative and quantitative yield of acoustic recordings for migration-related research and applications. Migration intensity estimated from weather radar data correlated best at low levels with acoustic records including all species in spring while in autumn passerine species showed stronger correlation than the entire species composition. Our findings identify a minor number of species whose call records may be eligible for applications derived from acoustics. Especially the highly vocal species Song thrush and Redwing showed relatively good correlations with radar and citizen science migration schedules. Most long-distance passerine migrants and many other migrants were not captured by acoustics and an estimated seasonal average of about 50% of nocturnally migrating passerine populations remained undetected. Overall, the ability of acoustic records to act as a proxy of overall migration dynamics is highly dependent on the migration period and species involved.

High‐intensity bird migration along Alpine valleys calls for protective measures against anthropogenically induced avian mortality

AbstractThe Alps are a natural barrier for avian broad‐front migration in Central Europe. While most birds that approach the Alps are deflected and circumvent the mountains, some choose to make the crossing. Here, they are funnelled and channelled in valleys, leading to high bird densities. Many Alpine valleys are suitable locations for wind farms, potentially creating a conflict between wind energy production and bird conservation. Collisions can be reduced by temporarily shutting down wind turbines. This however requires timely coordination, either by locally monitoring migration intensity or by extrapolating and forecasting migratory fluxes from other sites. However, little is known about the timing and intensity of bird migration in valleys of the central Alps, especially during spring migration. This study presents a 2‐year quantification of avian migration across the Alps. We collected terrestrial radar data at three sites: two located in Alpine valleys and one in the lowland, close to the northern foothills of the Alps. We found high migration traffic rates (MTR) during both migration seasons in the Alpine valleys, with outstanding numbers of migrants during the spring season. The strong alignment of the flight directions with the main orientation of alpine valleys highlights the importance of valleys and the connected passes in channelling migratory fluxes through the Alps. However, extrapolating migration intensities and forecasting peak migration events for inner Alpine sites is difficult, likely due to how migratory patterns and activity are influenced by the complexity of the local topography and the associated dynamic wind and weather conditions. Instead, we call for year‐round on‐site monitoring of migration intensities and strategies tailored to the local context to reduce the risk of bird strikes at wind turbines in the Alps.

Geography of population migration of the Southern Federal District

The article, based on state statistics, conducted a study of the transformation of geography and trends in the development of migration of the population of the Southern Federal District. Using an interdisciplinary integrated approach, an analysis of migration flows, their directions, scale and intensity was carried out, the geography of migrations of the most migratoryly attractive subject of the district - Krasnodar Territory - was determined, and mapping of migration indicators was carried out using modern information technologies for studying space and visualization.It is shown that, despite the decrease in migration turnover due to the coronavirus pandemic, the long- term trend of positive migration dynamics in the Southern Federal District has remained, and in terms of the intensity of net migration in 2021, the macroregion took first place among all Russian districts.There have been no major changes in the geography of incoming and outgoing migration flows. Intra- Russian migration is characterized by a migration outflow of the population to the Central and Northwestern federal districts, and migrants from all other districts, but most of all from Siberia and the Far East, come to the southern macroregion. The main flows of international migrants come from citizens of the CIS countries, primarily from Ukraine, Armenia, Kazakhstan, Tajikistan, Uzbekistan, and Azerbaijan.A comparative analysis of the migration movement of the subjects of the Southern Federal District showed that in the macroregion Krasnodar Territory ranks first in terms of the volume and effectiveness of migration, and in terms of the intensity of migration movement, it exceeds the Russian average. To date, the steady trend of positive dynamics in the migration balance that has developed in Kuban since the middle of the last century has been preserved. However, there has been a significant decline in net migration. The main modern vector of intra-Russian migration flows is movement to Kuban from the northern regions of Russia, Siberia and the Far East. Most international migrants arrived in the Krasnodar region from CIS countries. During the study period, the main suppliers of cross-border migrants were Ukraine, Armenia and Kazakhstan.

Мониторинг процессов внешней миграции как инструмент региональной миграционной политики

The dual nature of the influence of international migration on the level of economic development, social situation and national security of the host country is considered. The author evaluates both the role of external migration as a compensatory component of natural population decline at the current stage of development, and the negative effects of this process. Taking into account the specifics of the regional structure of the Russian Federation and its inherent differentiation in terms of the level of socio-economic development, in order to increase the validity of management decisions regarding the regulation of migration flows at the regional level, a system of statistical indicators is proposed in the form of a model set of diverse indicators that characterize the impact of migration flows on the economy of the region and social burden on the population. The author examines 6 main analytical areas: contingent load, migration intensity, migration load, migration efficiency, migration density, migration effectiveness, represented by relevant indicators. This system of indicators was the basis for conducting multidimensional cluster analysis in order to identify regions that have a similar profile in terms of the influence of external migration processes. As a result, 6 clusters were identified and described, which have significant differences in terms of the influence of external migration processes on the socio-economic characteristics of the region. The application of the approach under consideration, according to the author, will help improve the quality of migration flow management and the effectiveness of migrant adaptation policies at the regional level.

Внутрирегиональная и межрегиональная миграция населения Сибири: сравнительный анализ Иркутской, Томской областей и Красноярского края

The article focuses on the analysis of intraregional migration processes in Tomsk and Irkutsk Oblasts and Krasnoyarsk Krai. The aim of the article is the observation of trends and consequences of the interregional and intraregional migration processes in three Siberian territories. The basis of this study is the migration statistic data in Irkutsk and Tomsk Oblasts and Krasnoyarsk Krai. The authors use data that were both published in open access and obtained on individual request from the Russian Federal State Statistics Service (Rosstat). Migration statistics was analyzed by means of authors’ statistic calculations and visualization of these data by mapping the information. The migration situation in the Siberian regions is analyzed in the following steps: comparison of indicators and coefficients of migration growth/loss of interregional movements to identify the most and least intensive and productive migration connections of the regions; comparison of the coefficients of migration growth/loss of intraregional migrations to identify the main migration trends – donor-territories and recipient-territories within the regions; comparison of indicators and coefficients of migration intensity to identify the territories of the region with the most and least movable population. The data of intraregional migrations are the basis for the mapping of these processes. The comparison of data on interregional and intraregional migration in relation to the identification of centers of attraction and migration donors on a regional scale allowed identifying common patterns and regional specifics of these processes, as well as key migration trends and territories that are most actively involved in migration exchange. These approaches ensured the comparison of migration situation in three regions. The authors ascertain trends of sustainable population outflow from rural areas to large cities and concentration of intraregional migrants in cities of regional or district administration. Taking into account the movement of people to the central and southern regions of the country, described through the western shift concept, presumably, the intraregional migration trends that repeat directions of interregional migration flows can create extra conditions for negative migration processes in these regions. The results of the study allowed formulating a hypothesis about the correlation of the role of interregional and intraregional migration for the social and demographic development of Tomsk and Irkutsk Oblasts and Krasnoyarsk Krai.
