Le moment est donc idéal pour réfléchir à l'avenir de l'affichage publicitaire à Liège. Afin de lancer la réflexion, nous examinerons le cas de la Ville de Grenoble, qui a posé le choix audacieux de ne pas reconduire ce contrat. Quelles sont les raisons de cette décision ? Le contexte liégeois est-il similaire ? Quels sont les enjeux et perspectives de l'affichage dans l'espace public ? Le débat est ouvert ! [less ▲]

The modernization of the tannery of Maradi had intervened in 2009 with the introduction of the process of tanning in the chromium. We estimated the influence of this change of operating process through an evaluation of the impact characteristics evolution of the solid and liquid discharges of this tannery on water. It stands out that the modernization of the tannery activities had more or less significant effects on these environment elements. We noted a relative improvement of the quality of underground waters illustrated by the regression of the content in chloride and nitrates rates stabilization. While the content in chromium evolved in a significant way as well as the pH. However, all the four above parameters remain below WHO standards. By cons, this modernization has almost not influenced the impact on the quality of surface waters. The values of BOD and COD have continued to rise despite the installation of a treatment system. Thus this surface water, including the pond, proved to be a major public health risk for domestic and agricultural use and is also a source of air pollution. [less ▲]

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 ▲]
