Environmental migration is a topic which has given rise to widespread debate and gloomy predictions about the state of the world by 2050, but where rigorous research and empirical evidence are unfortunately in short supply. This study paper reviews the existing research on - and empirical evidence of - how climate change and climate variability in Less Developed Countries (LDCs) affects two main drivers of migration identified by migration models in the economic literature, namely: a) income level differentials between origin and destination areas and income variability in origin areas, and b) how they in turn affect migration. This paper highlights the need for a clearer picture of the driving force behind the link between rainfall and migration, which would in turn benefit policymaking in this area.
Ending poverty and stabilizing climate change will be two unprecedented global achievements and two major steps toward sustainable development. But the two objectives cannot be considered in isolation: they need to be jointly tackled through an integrated strategy. This report brings together those two objectives and explores how they can more easily be achieved if considered together. It examines the potential impact of climate change and climate policies on poverty reduction. It also provides guidance on how to create a “win-win†? situation so that climate change policies contribute to poverty reduction and poverty-reduction policies contribute to climate change mitigation and resilience building. The key finding of the report is that climate change represents a significant obstacle to the sustained eradication of poverty, but future impacts on poverty are determined by policy choices: rapid, inclusive, and climate-informed development can prevent most short-term impacts whereas immediate pro-poor, emissions-reduction policies can drastically limit long-term ones.
Gradual and sudden environmental changes are resulting in substantial human movement and displacement, and the scale of such flows, both internal and cross-border, is expected to rise with unprecedented impacts on lives and livelihoods. Despite the potential challenge, there has been a lack of strategic thinking about this policy area partly due to a lack of data and empirical research on this topic. Adequately planning for and managing environmentallyinduced migration will be critical for human security. The papers in this volume were first presented at the Research Workshop on Migration and the Environment: Developing a Global Research Agenda held in Munich, Germany in April 2008. One of the key objectives on the Munich workshop was to address the need for more sound empirical research and identify priority areas of research for policy makers in the field of migration and the environment.
"The migration of labor from rural to urban areas is an important part of the urbanization process in developing countries. Even though it has been the focus of abundant research over the past five decades, some key policy questions have not found clear answers yet. To what extent is internal migration a desirable phenomenon and under what circumstances? Should governments intervene and, if so, with what types of interventions? What should be their policy objectives? To shed light on these important issues, the authors survey the existing theoretical models and their conflicting policy implications and discuss the policies that may be justified based on recent relevant empirical studies. A key limitation is that much of the empirical literature does not provide structural tests of the theoretical models, but only provides partial findings that can support or invalidate intuitions and in that sense, support or invalidate the policy implications of the models. The authors' broad assessment of the literature is that migration can be beneficial or at least be turned into a beneficial phenomenon so that in general migration restrictions are not desirable. They also identify some data issues and research topics which merit further investigation. "--World Bank web site.
Migration presents a stark policy dilemma. Research repeatedly confirms that migrants, their families back home, and the countries that welcome them experience large economic and social gains. Easing immigration restrictions is one of the most effective tools for ending poverty and sharing prosperity across the globe. Yet, we see widespread opposition in destination countries, where migrants are depicted as the primary cause of many of their economic problems, from high unemployment to declining social services. Moving for Prosperity: Global Migration and Labor Markets addresses this dilemma. In addition to providing comprehensive data and empirical analysis of migration patterns and their impact, the report argues for a series of policies that work with, rather than against, labor market forces. Policy makers should aim to ease short-run dislocations and adjustment costs so that the substantial long-term benefits are shared more evenly. Only then can we avoid draconian migration restrictions that will hurt everybody. Moving for Prosperity aims to inform and stimulate policy debate, facilitate further research, and identify prominent knowledge gaps. It demonstrates why existing income gaps, demographic differences, and rapidly declining transportation costs mean that global mobility will continue to be a key feature of our lives for generations to come. Its audience includes anyone interested in one of the most controversial policy debates of our time.
As climate change and extreme weather events increasingly threaten traditional landscapes and livelihoods of entire communities the need to study its impact on human migration and population displacement has never been greater. The Atlas of Environmental Migration is the first illustrated publication mapping this complex phenomenon. It clarifies terminology and concepts, draws a typology of migration related to environment and climate change, describes the multiple factors at play, explains the challenges, and highlights the opportunities related to this phenomenon. Through elaborate maps, diagrams, illustrations, case studies from all over the world based on the most updated international research findings, the Atlas guides the reader from the roots of environmental migration through to governance. In addition to the primary audience of students and scholars of environment studies, climate change, geography and migration it will also be of interest to researchers and students in politics, economics and international relations departments.
"South-South Migration and Remittances" reports on preliminary results from an ongoing effort to improve data on bilateral migration stocks. It sets out some working hypotheses on the determinants and socioeconomic implications of South-South migration. Contrary to popular perception that migration is mostly a South-North phenomenon, South-South migration is large. Available data from national censuses suggest that nearly half of the migrants from developing countries reside in other developing countries. Almost 80 percent of South-South migration takes place between countries with contiguous borders. Estimates of South-South remittances range from 9 to 30 percent of developing countries' remittance receipts in 2005. Although the impact of South-South migration on the income of migrants and natives is smaller than for South-North migration, small increases in income can have substantial welfare implications for the poor. The costs of South-South remittances are even higher than those of North-South remittances. These findings suggest that policymakers should pay attention to the complex challenges that developing countries face not only as countries of origin, but also as countries of destination.
While major strides have been made in the scientific understanding of climate change, much less understood is how these dynamics in the physical enviornment interact with socioeconomic systems. This book brings together the latest knowledge on the consequences of climate change for society and how best to address them.
This book provides an authoritative analysis of the impact of climate change on migration.
International migration, the movement of people across international boundaries to improve economic opportunity, has enormous implications for growth and welfare in both origin and destination countries. An important benefit to developing countries is the receipt of remittances or transfers from income earned by overseas emigrants. Official data show that development countries' remittance receipts totaled 160 billion in 2004, more than twice the size of official aid. This year's edition of Global Economic Prospects focuses on remittances and migration. The bulk of the book covers remittances.
