Abstract:
Sahel zone has been reported as one of the most vulnerable regions to climate
change, so serious attention must be paid to this zone by researchers and development actors who are interested in environmental-human dynamics and
interactions. The aim of this study was to bring more insight into the impact
of actions aiming at reducing land degradation, regreening the Sahel, stopping population migration and reducing the pressure on land in the Sahelian
zone. The study focused on farmland dynamic in Ouahigouya municipality
based on remote sensing data from 1986 to 2016 using intensity analysis. The
annual time interval change was 0.77% and 2.46% for 1986-2001 and 2001-2016,
respectively. Farmlands gained from mixt vegetation, water bodies and from bar
lands. Mixed vegetation and water bodies were both active during both intervals
while the other land use such as woodland and bar land were dormant. Combining land use land cover analysis and intensity analysis was found to be effective for assessing the differentiated impact of the various land restoration actions.
