Abstract

Spatial and temporal changes in the water surfaces of the Nakanbe-Wayen watershed influence, at the local and national levels, sustainable economic development. However, these changes in the basin remain poorly characterized. The present study, which aims at analyzing the spatio-temporal dynamics of the water surfaces of lakes Bam and Dem, two wetlands of international importance in the said watershed, exploited the processing power of the Google Earth Engine (GEE) platform to analyze 2121 Landsat image scenes over the period from 2000 to 2020. The water surfaces extraction algorithm, based on a combination of water and vegetation index, has been tested and adopted to rapidly extract the water surfaces of said wetlands. The results indicate that: (1) the water surfaces extraction method is well suited to that of Bam and Dem lakes; (2) the areas of water surfaces have a significant shrinking trend respectively -22.80 ha/year (P-value=0.0006) and -4.44 ha/year (P-value=0. 009) of the permanent surfaces of Bam Lake and Dem Lake from 2000 to 2020; (3) changes in the water surfaces of these lakes may be associated with climate change and human activities and should be studied in more detail. In view of the significant loss of water surfaces areas and the importance of lakes Bam and Dem for the communities and the environment, taking into account strong and concerted actions for restoration and conservation is urgent in order to perpetuate these natural spaces.

The water surfaces extraction algorithm, based on a combination of water and vegetation index, has been tested and adopted to rapidly extract the water surfaces of said wetlands. The results indicate that: (1) the water surfaces extraction method is well suited to that of Bam and Dem lakes; (2) the areas of water surfaces have a significant shrinking trend respectively -22.80 ha/year (P-value=0.0006) and -4.44 ha/year (P-value=0. 009) of the permanent surfaces of Bam Lake and Dem Lake from 2000 to 2020; (3) changes in the water surfaces of these lakes may be associated with climate change and human activities and should be studied in more detail. In view of the significant loss of water surfaces areas and the importance of lakes Bam and Dem for the communities and the environment, taking into account strong and concerted actions for restoration and conservation is urgent in order to perpetuate these natural spaces.
