Agroecosystems are becoming more developed in Morocco, which requires conducting research about their importance to indigenous avifauna. We studied the influence of seasonality and parcel characteristics, including habitat type and anthropogenic pressures on bird diversity in vineyards. Our findings show that bird diversity varies by habitat type with heterogeneous parcels being more diverse than homogeneous parcels; in addition to that, bird diversity was higher in edge habitat, olive and uncultivated land while it was lower in vine habitat, whereas the cereal was the poorest habitat in the vineyards. Our results revealed that avian diversity changes with the seasons, being higher in winter, autumn and spring than in the summer. Evaluation of anthropogenic pressures indicates that avifauna diversity was negatively associated with the distance to the nearest building and the nearest edge, but positively associated with the distance to the nearest water source. Our research identifies potentially important variables influencing bird diversity in these agricultural ecosystems, which can help us to understand more clearly the ecological needs of birds of this habitat.As a result, we make some recommendations to help preserve bird diversity and improve their survival, including securing and protecting edge habitat, boosting habitat diversity and contributing to the overall effort to reduce climate change impacts, all of which will not be possible without the cooperation of landowners, farmers, managers and researchers.
Assessment of groundwater quality is important for drinking water, especially for rural populations. The aim of this study was to assess the groundwater quality for human consumption by integrating the water quality index with geographic information system (GIS) for the eventual interpretation of Meknes area water quality. Eight wells and two springs were investigated between February 2013 and February 2014. In light of the analysis results, spatial distribution maps of chosen physico-chemical parameters such as pH, O 2 , EC, Ca 2+ , Mg 2+ , SO 4 2− , NH 4 + , NO 3 − , NO 2 − , PO 4 3−, SO 4 2− and HCO 3 were prepared using GIS. Water Quality Index (WQI) approach is utilized with the groundwater parameters and spatial distribution maps have been developed using GIS for the obtained indexes. The anthropogenic activities may be the likely cause of poor water quality. The north and north-west regions are influenced by anthropogenic inputs from the leaching of landfill and wastewater, whereas the south-west region is affected by agricultural runoff due to a quite high level of agricultural activity. The WQI values varied from 28.88 to 187.18. According to WQI classification, 30% of samples are unsuitable for drinking water purposes. These findings indicate the need for serious reflection on the part of the planners and decision-makers for efficient management of the groundwater resources.
Groundwater in Morocco is restricted because of the semiarid to arid climatic conditions. In this area, the water resources, especially groundwater, are extremely significant. However, it is under threat from organic and inorganic pollution. Furthermore, it is considered the only source of potable water as well as having different usages in Zagora (the southeast of Morocco), making its quantitative and qualitative protection an urgent priority. The present study focused mainly on the anthropogenic impact on the natural resources and groundwater quality around Zagora city by using geospatial techniques and the Water Quality Index (WQI). This paper uses sampling data from 15 wells in the water table of Oasis Fezouata. 15 samples were collected from wells during rainy and dry seasons in two years 2020-2021 and the analysis of the groundwater quality of studied stations. The suitability of the aquifer Fezouata was investigated using drinking and irrigation water quality indices like SSP, SAR, MHs, PI, and KR. The results showed that sulfate and chloride are the dominant anions in the groundwater samples. While the mean abundance of major cations is Na+ > Mg2+ > Ca2+ > K+, the sodium ion is dominant and K+ is the least abundant. The Water Quality Index suggests that 28.55% are good quality water, (23.90%–47.55%) are poor and very poor quality water, respectively, and 40.24% are unsuitable for drinking purposes in 2020. Furthermore, the WQI of the 2021 campaign showed that only 17.48% were considered good quality water and 38.94% (43.58%) were poor or very poor quality water, respectively. However, 33.21% are unsuitable for drinking water. Based on SAR, PI, SSP, KR, and HM values, the majority of groundwater samples can be used for agricultural purposes, notably those of the upstream part of the study area. These results represent an important contribution to the evaluation of groundwater quality and may be influenced mainly by local factors, especially the wastewater treatment stations and mine discharges, which are the primary sources of deteriorating water quality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
