Analysis of the Spatio-Temporal Evolution of Artisanal and Small-Scale Gold Mining in Central Ivory Coast, West Africa

Ivory Coast is a country rich in base metals and precious minerals: gold, manganese, diamond, iron, bauxite, cobalt nickel. These natural resources are exposed to destruction fragmentation by mining activities. The artisanal small-scale exploitation of gold increasingly practiced our rural areas. activities escape often the control monitoring administration. In order better constrain these on environment, present work used remote sensing imageries see its spatio-temporal impacts world central Coast. results show that have been since 2013 experiencing an important growth. We note devastation forests savannahs, pollution surface water, as well increase poverty near habited areas (villages). This creates reduction cultivatable soil. Remote make it possible quickly map at large-scale time space.
