Human mobility affects land use and human density distribution. Unfortunately, this rarely takes into account the real and potential changes induced by hazards on the natural systems. Thus, migration and natural hazards should be constantly analyzed through cross-sectional and global studies to reduce disastrous consequences resulting from their mutual interactions. In a multi-risk and demographic sprawl context, the study focused on the cross-analysis of human density and natural hazards in Bujumbura. The results show that migration of people should ideally be guided by knowledge of the area's sensitivity to natural hazards, taking into account other parameters such as hazards susceptibility maps and production opportunities. While the migration of people toward overcrowded centers constitutes a big challenge, it is an important asset when it concerns areas in need of manpower. It also allows the balance in relieving saturated areas, reducing human pressure on the environment. Therefore, there is a need that policymakers comply with those aspects, finding the right balance for a better situation. [less ▲]

L’Afrique de l’Ouest est la région du monde qui connait le déficit pluviométrique le plus important. Le Niger, l’un des pays les plus pauvres du monde, est hautement dépendant des variations pluviométriques dans un contexte de réchauffement climatique dont les conséquences semblent être défavorables dans les décennies à venir. Sur base des données pluviométriques quotidiennes de 37 stations nigériennes, cet article analyse l’évolution des précipitations au travers de onze indices entre 1950 et 2014. Après une sévère sécheresse de trois décennies qui est individualisée de 1968 à 1997, il apparait que si un retour à une pluviométrie moyenne annuelle subnormale est observé depuis 1998, il n’en est rien pour d’autres indices vitaux pour le monde rural dépendant de la bonne distribution des précipitations durant la saison des pluies. En effet, les jours secs consécutifs ont considérablement augmenté et les jours humides consécutifs se sont réduits. Il en va de même pour les jours pluvieux. Dans le même temps, la proportion de la précipitation maximale quotidienne dans le total pluviométrique annuel s’est renforcée au fil du temps et la proportion des précipitations intenses dans le total pluviométrique annuel s’est significativement accentuée au cours des deux dernières décennies [less ▲]

The land-sea interface is an extremely fragile environment. On a global scale, coastlines are threatened by a multitude of factors sometimes natural and mostly anthropogenic. Thus, in addition to the disruptions to coastal areas by port facilities, dams, sediment sampling on the beach or urban sprawl, there are the consequences of climate change, including rising sea levels. The objective of this study is to assess recent trends (between 2000 and 2015) of the coastline in Togo and Benin where more localized studies show that sandy beaches are experiencing major changes (accretion or erosion) in recent decades. Coastal dynamics are analyzed using very high spatial resolution images available in open access on Google Earth; the coast is studied by section of 1 km on a coastline of 170 km by calculating the average change in meter per year since 2000. Analysis of coastal Togo and Benin shows that only 34% of the coastlines (most of the time protected) are stable and that accretion is recorded only upstream of harbor infrastructures (14%). Elsewhere, coastlines undergo erosive processes (52%), sometimes exceeding annual average retreats of 10 meters per year. In such conditions, villages have disappeared during the past decade and a large number of people have been displaced. [less ▲]
