“…The total precision values calculated for our study area are shown in Tab 6. Knowing that the critical value for the acceptance of this classification is 75% [21][22]. Therefore, we can conclude that there is an excellent correspondence between the mapping obtained from the classification of remote sensing data and the field observations.…”

Hydrological drought is considered an environmental phenomenon related to climate changes that affect natural resources in general. The evaluation of droughts is essential to in the management ofwater resources. This study aims to demonstrate the use of statistical indices (SSFI and NHI) andGIS (remote sensing) to quantify, characterize and identify hydrologic drought. These indices are applied to the watershed of OuedEl-Abid using the annual stream flows time series at the threestations studied (AitOuchen, Tilouguit, and TiziN’Isli), spanning from 1978 to 2019. Results showed that dry and very dry years occur more frequently. Because of, the lake of Bin El-Ouidane dam ismarked by a substantial regression of the water storage. Thematic maps of land use using spatialremote sensing (supervised classification) show that the years 1984, 2000, and 2017 are the driestand most vulnerable years.

“…According to which, over the last three decades, the dam has experienced very significant variations in its water height and impoundment, the general trend of which tends to recede with a decrease of almost 40% (Fig. 5) thanks to the occurrence of drought episodes [20][21][22][23][24].…”

“…Equally, the airport infrastructure of the Beni Mellal-Khénifra region consists of a single airport "Beni Mellal airport" of 170 ha located 8 km northwest of the city, with a capacity of 150,000 passengers per year. On the other hand, the region is dominated by rivers counting Oum Er-Rbia, Derna, El Abid, Lakhdar and Tassout (Barakat et al 2016;Layati et al 2021), forest potential of 443,500 ha (Barakat et al 2018), and agricultural fields that cover 948,426 ha (Abouhani 2001). These elements are suggested to influence bird communities in the area.…”

Urban expansion leads to modifications of habitat features, organization, and resources. Bird assemblages are known to respond by escaping destructive changes and adapting to sustainable ones. In this study, we investigated for the first time the avian diversity and its variation following the rural-urban gradient in Beni Mellal (Morocco) from 2018 to 2021. We used the line-transect method and multivariate analysis to demonstrate the selection of breeding habitats. Our result revealed a total of 84 species divided into resident breeders (64.28%), passage migrants (17.85%), breeding migrants (26.19%), winter visitors (32.18%) and accidental visitors (1.19%). Two globally vulnerable species counting the European Turtle Dove Streptopelia turtur and the European Goldfinch Carduelis carduelis were recorded. Breeding populations were concentrated in green spaces (9 species) located in the urban zone, compared with farmlands (7 species), peri-urban (3 species), and rural areas (3 species). Therefore, these results reverse the hypothesis that rural and farming lands are more species-rich because of a higher population size. This is due to the abundance of breeding and foraging resources in urban green spaces compared to arid lands surrounding cities in this North African area. Furthermore, our study provides a new opportunity for comparative studies of avian diversity in Morocco and Northwest Africa.
