Migration-related land use dynamics in increasingly hybrid peri-urban space: insights from two agricultural communities in Bolivia

This article investigates the impact of transnational labor migration on agriculture in urbanizing communities in Bolivia. Previous research shows that the characteristics of rural out-migration communities affect whether agricultural practices are intensified and improved. Using a mixed methods approach, two closely located peri-urban communities with distinct prerequisites for agricultural development are analyzed. This study shows weak migration-induced changes in agriculture and concludes that transnational migration does not necessarily accelerate an ongoing urbanization process. It shows that remittances function to maintain farming for subsistence and as a secondary livelihood activity. However, major investments in agricultural intensification are not attractive due to the communities’ proximity to the main cities. This article highlights the need for nuanced conceptualization when studying migration-driven agricultural change in hybrid peri-urban spaces.     

Labour migration and investments by remaining households in rural Nepal

Existing studies on the development effects of labour migration and remittances provide conflicting evidence and many suffer from self-selection bias. Furthermore, in spite of the significance of labour migration to the Nepalese economy, there are very few studies that formally analyse the development effect of labour migration in this region. Consequently, propensity score matching and a ‘difference-in-difference’ method is used to estimate the effect of labour migration and expectations to receive remittances from these migrants on investments by the remaining households in Chitwan, Nepal. The results suggest a positive role of labour migration and their likelihood of sending remittances on investments in agriculture, a type of productive investment.     

Female Migration and Child Occupation in Rural El Salvador

This article looks at the consequences of migration in terms of child education and child labor using a unique rural panel dataset for El Salvador. Results suggest gender differences in the consequences of migration on child activities that remain in El Salvador. While female migration tends to reduce child labor, both in domestic and non-domestic activities, male migration seems to stimulate it, in particular in terms of domestic labor. In contrast, while male migration has null or slightly positive impact in terms of school enrollment rates, female migration apparently reduces the likelihood that a particular child stays at school. Some of these results differ according to the gender of the child. The results do not seem to be driven by female migrants remitting more than males, but rather to alternative competing explanations, such as the existence of child–adult male labor substitution, differences in the use of remittances by gender of the recipient person, or limited ability to monitor funds when remitted by female migrants.     

Land and leña: linking transnational migration, natural resources, and the environment in Guatemala

This article examines the relationships between international migration, natural resources, and the environment. Rather than looking at environmental change as a cause of population movements, the article reveals how migration affects the environment in sending countries. Empirically, we rely on a case study in Guatemala. Although migrants and cash remittances make significant contributions to Guatemala’s changing economy, little is known about the relationships between migration and the environment in this Central American country—a country, which continues to have a large rural population and that relies heavily on its natural resources. Drawing on ethnographic research and household surveys in a Maya community, we reveal how migrants and their earnings, as well as their ideas, behavior and attitudes, affect land use, land cover, and firewood use. We reveal, for example, how in addition to investments in land for home building and pick-up trucks to help improve agricultural production, some migrant households purchase more land and often dedicate it to the cultivation of vegetable crops for local and foreign markets. Cultural practices and beliefs directly linked to land and the environment, particularly maize cultivation, also alter due to migration processes. And, despite the ability of migrant households to transition to more efficient fuels like liquid propane gas (LPG), we show how they continue to use firewood. In all, the study contributes important insights into the environmental implications of migration.     

Rural–urban migration, agrarian change, and the environment in Kenya: a critical review of the literature

The nexus between migration dynamics and environmental change has drawn the attention of many researchers in the recent past. While the majority of studies focus on the impact of the environment on migration decisions, less emphasis has been placed on the feedback effect of migration on the environment in rural sending areas. This article provides a critical review of this relationship by focusing on the rich literature on rural–urban migration of smallholder households in Kenya and its effects on rural environments. The article argues that there are distinct relations between migration, agricultural change and the environment. These are mediated in varying degrees by flows of remittances, loss of labor, socioeconomic stratification, gender dynamics, and cultural factors. Overly generalizing assumptions about these relations, however, fail to grasp their complexity. We propose employing a translocal perspective to enrich future analysis and enhance the understanding of migration–environmental interactions.     

Remittances in the Republic of Georgia: Correlates, Economic Impact, and Social Capital Formation

The economic impact of remittances on migrant-sending countries has been a subject of debate in the scholarly literature on migration. We consider the topic using a household-level approach. We use a new survey, “Georgia on the Move,” to examine migrant-level, household-level, and contextual variables associated with the probability that a household in the Republic of Georgia receives remittances. We then apply propensity score matching to estimate how remittances affect particular types of household expenditures, savings, labor supply, health, and other measures of well-being. Separate analysis of the subsample of households with a migrant currently abroad distinguishes the effects of remittances from the effects of migration as such. In Georgia, remittances improve household economic well-being without, for the most part, producing the negative consequences often suggested in the literature. We find evidence for an important aspect that has not been widely discussed in prior studies: remittances foster the formation of social capital by increasing the amount of money that households give as gifts to other households.     

How Job Characteristics Affect International Migration: The Role of Informality in Mexico

Despite the importance given to employment opportunities as a primary motive for migration, previous studies have paid insufficient attention to the kinds of jobs that are more likely to retain workers in their countries of origin. We use information from a panel survey of Mexican adults to examine how job characteristics affect the risk of international migration. The sampling strategy and overall size of the survey allow us to analyze the effect of employment characteristics on migration from urban areas, which have much greater labor market diversity, and to separate our analysis by gender. We also distinguish migrants according to whether they migrate for work or for other reasons. We find informality to be a significant predictor of international migration. Even after controlling for individual factors including workers’ wages, as well as various household- and community-level predictors, we find that workers employed in the informal sector have significantly higher odds of migrating than their counterparts in the formal sector. The pervasive nature of informality in many developing countries from which a high proportion of international migrants originate may therefore create a constant supply of workers who are predisposed to migrate. Our findings thus have important implications for a proper understanding of the effects of economic development on migration.     

Migrant remittances in Thailand: Economic necessity or social norm?

The remittances of internal migrants contribute in various ways to the well-being of their households of origin. This study examines the significance of selected socio-economic and demographic factors associated with remittance behaviour in Thailand as characterized by the propensity to remit and amount remitted. The extent to which remittances affect the living standard of house-holds left behind is also appraised. The analyses suggest that in Thailand sending remittances is a practice rooted in altruism which enables out-migrants to retain personal contact with their households of origin for an extended time. Thus, it is widely exercised regardless of the economic needs of the household. At the same time, out-migration is an effective means for low-income households to quickly overcome shortages of income. The sustenance of poor households might have been difficult without remittances. From a macro-perspective, remittances contribute to the equalization of the income distribution among households having out-migrants.     

Out-migration and land-use change in agricultural frontiers: insights from Altamira settlement project

One of Daniel Hogan??s lasting impacts on international demography community comes through his advocacy for studying bidirectional relationships between environment and demography, particularly migration. We build on his holistic approach to mobility and examine dynamic changes in land use and migration among small farm families in Altamira, Pará, Brazil. We find that prior area in either pasture or perennials promotes out-migration of adult children, but that out-migration is not directly associated with land-use change. In contrast to early formulations of household life cycle models that argued that aging parents would decrease productive land use as children left the farm, we find no effect of out-migration of adult children on land-use change. Instead, remittances facilitate increases in area in perennials, a slower to pay off investment that requires scarce capital, but in pasture. While remittances are rare, they appear to permit sound investments in the rural milieu and thus to slow rural exodus and the potential consolidation of land into large holdings. We would do well to promote the conditions that allow them to be sent and to be used productively to keep families on the land to avoid the specter of extensive deforestation for pasture followed by land consolidation.     

Buying membership in the transnational community:migrant remittances,social status,and assimilation

I analyze the effects that social status and immigrant incorporation have on migrant remittances. Understanding remittances as one type of transnational practice, I conceptualize them as the fee that migrants pay to remain members of the transnational community. I define a “status hypothesis” in terms consistent with the view of transnational engagement as a response to status loss, predicting a negative association between increases in social status and remittances. Since immigrant incorporation usually entails status gain, this hypothesis is consistent with the conventional assimilation paradigm. While the status hypothesis could be linked to the new economics of labor migration as well, it collides with the view of transnationalism as an alternative path for successful immigrant incorporation. Using data on male Mexican migrants to the United States, I find enough support for the status hypothesis, indicating the need to clarify the ultimate meaning of transnational practices. In addition, my analysis shows that there is room to integrate economic theory, the assimilation paradigm, and the transnational perspective into a comprehensive understanding of transnational engagement.

The effect of remittances on emigration intentions in Egypt, Morocco, and Turkey

Are remittances determined by altruism or enlightened self-interest, and do they trigger additional migration? In this paper these two questions are examined empirically in relation to data from Egypt, Turkey, and Morocco for households with family members living abroad. It is shown, firstly, that one cannot argue exclusively either for altruism or self-interest as motives, since for each country the data tell a different story and both motives can be identified as driving forces behind remittance behaviour. The general conclusion of this study is that the family ties and the net earnings potential of migrants have stronger effects on the flow of remittances than the net earnings potential of the households in the country of origin. Secondly, because the receipt of remittances has a positive effect on the emigration intentions of household members still living in the country of origin, the receipt of remittances may contribute to new flows of migration, particularly in the case of Morocco.     

Bombay migration study: A pilot analysis of migration to an Asian metropolis

This paper reports on a pilot study of migration to Greater Bombay, initiated on the recommendation of the Population Commission of United Nations, and utilizes both published tables from the 1961 Census of India and a set of specially prepared tables from the same census. Migrants were defined by birthplace and cross-classified by age and duration of residence in Bombay.Data (1901-61) on net migration (obtained from successive age-sex distributions) are analyzed in terms of underlying trends to give historical perspective to the analysis of recent data with special emphasis on changes in industrial and occupotiona structure.For the 1951-61 decade, the extensiveness of out-migration of former in-migrants, its age-sex selectivity, and its high incidence among recent migrants are demonstrated. As is true elsewhere, migration to Bombay is shown to be highly selective for ages of maximum economic activity. Migration streams to Bombay were preponderantly male, and, among males, the married segment predominated. The propensity to migrate was unusually high among minority religious groups. As to educational level, migrants were superior to the general population at origin but inferior to nonmigrants residing in Bombay. The work participation rates of migrants were higher for every age group than for resident nonmigrants; the proportion of employees was higher; and there was evidence of migrant concentration in industries and occupations requiring less skill, less education, and less capital than was true of nonmigrants. There were significant tendencies toward "division of labor" among various migration streams on the basis of skills and abilities acquired not only by formal education but also through tradition and precept. From the standpoint of the promotion of social change, the large volume (and selectivity) of reverse or return migration is especially note-worthy.The paper concludes with a methodological evaluation of the reliability and validity of duration-of-residence data and indicates that the relatively simple techniques of enumeration and tabulation utilized in this pilot study may have wide applicability in other developing countries.     

The Consequences of Migration to the United States for Short-Term Changes in the Health of Mexican Immigrants

Although many studies have attempted to examine the consequences of Mexico-U.S. migration for Mexican immigrants’ health, few have had adequate data to generate the appropriate comparisons. In this article, we use data from two waves of the Mexican Family Life Survey (MxFLS) to compare the health of current migrants from Mexico with those of earlier migrants and nonmigrants. Because the longitudinal data permit us to examine short-term changes in health status subsequent to the baseline survey for current migrants and for Mexican residents, as well as to control for the potential health selectivity of migrants, the results provide a clearer picture of the consequences of immigration for Mexican migrant health than have previous studies. Our findings demonstrate that current migrants are more likely to experience recent changes in health status—both improvements and declines—than either earlier migrants or nonmigrants. The net effect, however, is a decline in health for current migrants: compared with never migrants, the health of current migrants is much more likely to have declined in the year or two since migration and not significantly more likely to have improved. Thus, it appears that the migration process itself and/or the experiences of the immediate post-migration period detrimentally affect Mexican immigrants’ health.     

Vector representation of migration streams among selected state economic areas during 1955 to 1960

This paper uses in-migration, out-migration, and net migration vectors to measure and portray the migration streams occurring between April 1, 1955, and April 1, 1960, for all persons five years old and over on April 1, 1960, among 38 contiguous state economic areas (SEA's) in Oklahoma, Colorado, Kansas, Missouri, Arkansas, Texas, and New Mexico. Both rectangular and polar coordinates were employed in computing three different types of vector representations. First, migration vectors for each SEA, expressed in total people-miles of in-movement, out-movement, and net movement represent the resultant direction of movement and the total people-miles of movement. Second, in- and out-migration vectors of the total people-miles of movement, with the widths of the vectors drawn proportional to the number of migrants, show the total size of each migration stream for each SEA, the resultant direction of movement, and the distance moved in total people-miles of movement. p ]Third, in- and out-migration vectors of the average distances moved to and from each SEA, with the widths of the vectors drawn proportional to the number of migrants, show the magnitude of movement, the average distance moved per migrant, and the resultant direction of movement. This study shows that migration vectors based upon polar coordinates are more accurate than the migration vectors based upon rectangular coordinates. Also, the in- and out-migration vectors are superior to net migration vectors in representing migratory streams among geographic areas.     

Remittances and the income distribution in Tonga

Receipt of remittances from migrants decreased the inequality of income in Tonga. Policies that attempt to affect migration or remittance flows, such as policies to improve the administration and collection of taxes, should take into account any undesirable effects on the distribution of income.     

Networks Versus Need: Drivers of Urban Out-Migration in the Brazilian Amazon

As urbanization rates rise globally, it becomes increasingly important to understand the factors associated with urban out-migration. In this paper, we examine the drivers of urban out-migration among young adults in two medium-sized cities in the Brazilian Amazon—Altamira and Santarém—focusing on the roles of social capital, human capital, and socioeconomic deprivation. Using household survey data from 1,293 individuals in the two cities, we employ an event history model to assess factors associated with migration and a binary logit model to understand factors associated with remitting behavior. We find that in Altamira, migration tends to be an individual-level opportunistic strategy fostered by extra-local family networks, while in Santarém, migration tends to be a household-level strategy driven by socioeconomic deprivation and accompanied by remittances. These results indicate that urban out-migration in Brazil is a diverse social process, and that the relative roles of extra-local networks versus economic need can function quite differently between geographically proximate but historically and socioeconomically distinct cities.     

International labor migration and domestic labor supply

Prominent among the variety of issues raised by the immigration of labor are its effects on domestic wage rates and labor supply. In contrast to the existing literature, this paper constructs a dynamic, general equilibrium framework to study the relationship between international labor migration and domestic labor supply. The general equilibrium nature of the model enables us to endogenize the pattern of labor migration. The effect of labor migration on domestic wage rates and labor supply is shown to depend on the pattern of labor migration. If the substitution effect dominates the income effect in labor supply, the domestic supply of labor necessarily decreases in response to an inflow of migrants. This happens even if immigrants, through their savings behavior, cause an increase in the domestic capital-labor ratio and wage rate. Similarly, if the dominant effect is the income effect, the immigration of labor necessarily increases the domestic supply of labor.I wish to thank Oded Galor, Harl Ryder, Kalpana Kochhar and two referees for valuable comments. The opinions expressed in this paper are my own and do not necessarily reflect the views of Joel Popkin and Company.     

The effects of migrant remittances on population–environment dynamics in migrant origin areas: international migration, fertility, and consumption in highland Guatemala

International migration impacts origin regions in many ways. As examples, remittances from distant migrants may alter consumption patterns within sending communities, while exposure to different cultural norms may alter other behaviors. This paper combines these insights to offer a unique lens on migration’s environmental impact. From an environmental perspective, we ask the following question: is the likely rise in consumption brought about by remittances counterbalanced by a reduction in fertility in migrant households following exposure to lower fertility cultures? Based on ethnographic case studies in two western highland Guatemalan communities, we argue that the near-term rise in consumption due to remittances is not counterbalanced by rapid decline in migrant household fertility. However, over time, the environmental cost of consumption may be mitigated at the community level through diffusion of contraception and family planning norms yielding lower family size.
