This study aims to trace the situation of land use from 2005 to 2020 and its future at the end of this period to identify changes likely to establish a co-evolution between the state of ecosystems and the proliferation of stinking locusts. To achieve this, Landsat 7 and 8 images from 2005, 2010, 2015 and 2020 were uploaded to the US Geological Survey website platform: https://earthexplorer.usgs.gov. A classification was carried out using the ENVI software and the results were exported to ArcGIS for the editing and production of maps. During the 15-year period studied, forest cover decreased by 202.5 km2. As for the grassy and shrub savannah, they increased by 194.4 and 32.8 km2 respectively. The recorded decrease in forest in favor of an increase in grassy and shrub savannah in the Mawanga sector during the 15 years under study can explain the proliferation of stinking locusts infesting cassava cultivation. The increase in the area of grassy savannah and the decrease in that of forest present favorable conditions for the proliferation of stinking locusts. Despite the increase in the area of shrub savannah, this situation masks the degradation of this ecosystem favoring low humidity conducive to the multiplication of the stinking locust.

Abstract: (french)
Cette étude vise à tracer la situation de l’occupation des sols de 2005 à 2020 et son devenir au terme de cette période pour identifier des changements susceptibles d’établir une co-évolution entre l’état des écosystèmes et la prolifération des criquets puants. Pour y parvenir, des images Landsat 7 et 8 des années 2005, 2010, 2015 et 2020 ont été téléchargées dans la plateforme du site de l’US Geological Survey: https://earthexplorer.usgs.gov. Une classification a été réalisée grâce au logiciel ENVI et les résultats de celle-ci ont été exportés dans ArcGIS pour l’habillage et la production des cartes. Au cours de la période de 15 ans étudiée, la couverture forestière a diminué de 202,5 Km2. Quant à la savane herbeuse et arbustive, elles ont augmenté de 194,4 et 32,8 Km2 respectivement. La diminution enregistrée de la forêt en faveur de l’augmentation de la savane herbeuse et arbustive dans le secteur de Mawanga pendant les 15 années sous-étude peut expliquer la prolifération des criquets puants infestant la culture de manioc. L’augmentation de la superficie de la savane herbeuse et la diminution de celle de la forêt présentent des conditions favorables à la prolifération des criquets puants. En dépit de l’augmentation des superficies de la savane arbustive, cette situation masque la dégradation de cet écosystème favorisant une faible hygrométrie propice à la multiplication du criquet puant.
