This study aims to investigate the relation between mega-gully (> 5 m width) distribution and urbanization in Kinshasa (D.R. Congo), to establish what governs mega-gully location and plan form and to illustrate the concepts behind mega-gully treatment. For this purpose, the diachronic distribution of mega-gullies has been mapped in Kinshasa. All mega-gullies have been reported in ArcGis 9.3 on the orthorectified SPOT 2007 image. A newly elaborated DEM enables the mega-gullies to be placed in their natural topographical context. The GIS inventory on the SPOT 2006/2007 anaglyph indicates the mega-gully situation in the high town of Kinshasa 5 years ago: 308 mega-gullies with a cumulated length of 94.7 km, a mean drainage density of 0.4 km km− 2 and an average width and depth of 17 m and 6 m respectively. On the WorldView 1 (WV1) coverage, the number of mega-gullies has more than doubled between 2007 and 2010 from 160 to 334. The study shows that mega-gullies only develop within the urbanized perimeter of the high town of Kinshasa and only 5 to 10 years after incipient urbanization. The study also indicates that neither the location, the plan form or the downslope course of mega-gullies in Kinshasa are controlled by the natural topography. Forty-three point eight percent of the mega-gullies in Kinshasa are ‘axial’, occupying urban structures which function as artificial runoff drainage lines: roads, tarred or not, with or without side-road trenches, gutters in all forms and materials from concrete to sand, also foot paths and further all artificial runoff drainage lines. The study reveals that every mega-gully is directly or indirectly induced by human activities, but that every gully also finally ends to grow after an initial phase of sudden development. Mega-gully treatment follows two principles, often combined. The first is to stop the alimentation of the mega-gully head with water. The second includes a complete stabilization of the channel and walls inside the mega-gully. This study emphasizes that gully prevention can basically be achieved by control of the runoff discharges in the artificial stream network, as well as beside the roads. [less ▲]

Over the last decades, environmental changes driven and/or compounded by population pressures and climate change have dramatically impacted human mobility, including population displacements or migration, especially in developing countries. Slow onset degradation processes (aridification, desertification, wind and water erosion, deforestation, shoreline erosion, etc.) and sudden disasters (extreme climate events such as floods, droughts, storms, heat waves, etc.) have intensified since the 1950s in terms of frequency, intensity and duration, as well as in their socio-economic consequences. In the absence of an international objective to reduce greenhouse gas emissions, global warming and its wide range of negative impacts are not likely to be contained in the future [...] [less ▲]

S’il faut en croire les échos qui nous parviennent de vos négociations, vous vous seriez accordés sur un report de la mise à l’arrêt des réacteurs Doel 1 et 2 ; initialement prévue pour 2015, la cessation d’activité surviendrait in fine en 2025. Nous tenons à vous exprimer notre surprise, notre déception et notre crainte face à cette décision. [less ▲]
