Abstract
This study proposes an environmental management model for sand and gravel quarries along the coastline from Doukkala to Abda. It aims at the one hand; the creation of a regional database bringing together all the quarries to identify and characterize the materials exploited as well as the major impacts and risks associated with subsequent physiographic changes; and on the other hand to develop intervention mechanisms to prevent, reduce or even eliminate the harmful effects of abusive exploitation on the environment and public safety, while taking into account the specificities of the region.
Highlights
The opening and exploitation of quarries on a national scale are experiencing considerable growth due to the real estate and tourism boom and the policy of major structuring projects
The approach undertaken consists of: i/ the constitution of a regional database necessary to identify and characterize the materials exploited, the quarry sites, the major impacts and the risks linked to physiographic modifications and ii/ the development of the mechanisms of intervention to prevent, reduce or even eliminate impacts on the environment and public safety while taking into account the specificities of the region
The major impact problems posed by the various quarries in the region and the risks due to the physiographic modifications of the sites were assessed according to the three categories of materials, namely: the sand of the littoral rim, alluvial material on the river beds Oum Rbia and Tensift and the rocky stones of Sidi Bennour, Youssoufia and the province of Safi
Summary
The opening and exploitation of quarries on a national scale are experiencing considerable growth due to the real estate and tourism boom and the policy of major structuring projects (ports, dams, highways, etc.). While awareness of the problems of career management has given rise to a new law on the exploitation of quarries, it lacks implementing texts to regulate the exploitation of quarries effectively. In this perspective, the present study, devoted to the coastal quarries of the Doukkala-Abda coastal line, falls (Fig. 1). The present study, devoted to the coastal quarries of the Doukkala-Abda coastal line, falls (Fig. 1) It is a question of arriving at a reasoned and controlled management of these quarries while maintaining a balance between socio-economic development and preserving the environment, namely protecting landscapes, sites, and sensitive natural environments
