A la faveur de la culture de l’anacarde, savanes et forets des zones Nord de la Cote d’Ivoire sont transformees en de vastes vergers d’anacardiers. Ces travaux visent a analyser les modifications du paysage dans les espaces ruraux au Sud-Ouest du Parc National de Comoe (PNC), patrimoine mondial de l’Unesco. De facon specifique, il s’est agi de : (i) cartographier a partir de trois images satellitaires Landsat acquises respectivement les 29/01/2002, 02/12/2006 et 23/02/2014, l’occupation du sol des espaces ruraux au Sud-Ouest du parc national de Comoe et de (ii) suivre la dynamique des differents types d’occupation du sol de 2002 a 2014. Les resultats ont revele que les surfaces occupees par la culture de l’anacarde dans la zone couverte par cette etude sont passees de 11 743 hectares en 2002 a 29 872 hectares en 2014 (soit plus de 160%), tandis que les surfaces des forets (galeries forestieres et forets denses seches) ont fortement regresse et sont passees de 26 242 hectares en 2002 a 6 133 hectares en 2014 (soit -76%). Si la dynamique actuelle du paysage se poursuit, le PNC risque a moyen terme d’etre objet de convoitise par les populations rurales, ce qui fragiliserait sa preservation et sa conservation. © 2019 International Formulae Group.

This work aims to analyze landscape changes in the rural areas in the South-West of the Comoe National Park (CNP) which is known as Unesco World Heritage. Specifically, it consisted of: (i) mapping from three Landsat satellite images acquired respectively on 2002/01/29, 2006/12/02 and 2014/02/23, the land use of the South-West of Comoe National Park, and (ii) monitor the dynamics of different types of land use from 2002 to 2014. The results revealed that the areas covered by the cashew crop in the study zone increased from 11,743 hectares in 2002 to 29,872 hectares in 2014 (ie more than 160%), while forest areas (galleries forest and dry dense forests) declined sharply from 26,242 hectares in 2002 to 6,133 hectares in 2014 (ie -76%). If the current dynamics of the landscape continues, the CNP could be coveted by the rural populations, in the medium term, so that would weaken its preservation and conservation. © 2019 International Formulae Group.
