Climate Change, Natural Disasters and Migration: An Empirical Analysis in Developing Countries

The aim of this paper is to assess the relationship between natural disasters caused by climate change and migration by examining migration rates and levels of education in developing countries. Many studies such as the Stern review (2007) or the Intergovernmental Panel on Climate Change (IPCC, 2007) predict an intensification of climate change for future years. Thus climate change has taken an essential place in world governance. The relationship between climate change, natural disasters and migration is crucial; developed countries need to manage the increasingly complicated issues of additional incoming migratory flows caused by environmental degradation. We investigate this relationship by using panel data from developing countries in order to see the effect of natural disasters on migration rates and how that varies according to the level of education. Estimations are made with a country fixed effects estimator through an accurate econometric model. The results confirm previous studies, namely that natural disasters are positively associated with emigration rates. But beyond this result, the main contribution of this paper is to show that natural disasters due to climate change exacerbate the brain drain in developing countries characterized by the migration of highly skilled people just when those countries are at their most vulnerable and need greater support from skilled workers to deal with the damage associated with natural disasters. The paper also shows that this effect varies depending on geographical location.natural disasters, climate change, migration

“Barcelona or die”: understanding illegal migration from Senegal

Green tea is claimed by news media and scientists alike to be a source of health benefits for many conditions in humans. However, with the supposed health benefits of green tea ranging from ultraviolet light protection to memory improvement to weight management, it can be difficult to separate fact from fiction. Because tea is the most consumed beverage in the world, aside from water, even small beneficial health effects in humans could result in significant effects on global public health. I conducted a critical review of the research literature on green tea and human health and analysed the validity of these claims. While epidemiological studies look promising, clinical and laboratory trials to date are not compelling, requiring large doses and producing poorly defined benefits

Le numérique dans l’accès aux soins de santé au Sénégal : un pas vers la CSU ?

L’étude du cas du Sénégal montre que la mise en place du numérique dans le secteur de la santé doit s’accompagner de l’amélioration de l’efficience des dépenses de santé, de meilleurs systèmes d’éducation et de formation et la mise en place d’infrastructures performantes, entre autres. Le numérique n’est donc pas une panacée. Cependant, s’il est bien exploité, il a le potentiel de créer de grands bouleversements positifs dans le fonctionnement des systèmes de santé et la mise en place effective d’une couverture santé universelle en Afrique

Natural Disasters and Human Mobility

This paper reviews the effect of natural disasters on human mobility or migration. Although there is an increase of natural disasters and migration recently and more patterns to observe, the relationship remains complex. While some authors find that disasters increase migration, others show that they have only a marginal or no effect or are even negative. Human mobility appears to be an insurance mechanism against environmental shocks and there are different transmission channels which can explain the relationship between natural disasters and migration. Moreover, migrants’ remittances help to decrease households’ vulnerability to shocks but also dampen their adverse effects. The paper provides a discussion of policy implications and potential future research avenues
