“…The importance of conducting studies over the MENA region lies mainly in the potential catastrophic impact on human health [15,[25][26][27], and the difficulty of the population of these countries to mitigate or adapt to these impacts. Recent studies have focused on the future difficulties that the MENA region will face in terms of water demands, high population growth, sudden flows of refugees and economic development [28][29][30][31].…”

The duration and intensity of future heat waves are analyzed for 53 cities in the Middle East and the North Africa (MENA) region for the 21st century under two different scenarios (RCP4.5 and RCP8.5). A consistent approach is carried out using data from 13 Regional models within the framework of the Coordinated Regional Climate Downscaling Experiment (CORDEX). By the end of the century, 80% of the most populated MENA cities are expected to be at least 50% of the days under heat wave conditions during the warm season. In addition, the mean and maximum intensity of the heat waves will also increase. Changes in the duration and intensity of heat waves have shown to be negatively correlated. Therefore, the vulnerability of the MENA cities to future heat waves was determined using a cumulative index (CI) that takes into account both duration and intensity. This CI indicates that Middle East and the eastern part of Africa will suffer the most unfavorable temperature conditions in the future. Assuming no intervention trough adaptation/mitigation strategies, these results, together with the particular properties of the MENA region, such as aridity or lack of precipitation, make it likely that the area will be affected by disease or famine.

“…In Egypt, there are different environmental applications of remotely sensed data and GIS which are extensively utilized for assessing, modeling and monitoring different environmental variables and problems [e.g. [47][48][49][50][51][52][53][54][55][56][57][58][59]. Adding the application of mosquito studies will reinforce sustainability and vulnerability studies which will be adopted in the upcoming studies for supporting the Egyptian developmental plans.…”

El-Fayoum governorate has unique characteristics which induces mosquito proliferation and thus increased the risk arisen from diseases transmission. Present study explores the role of remote sensing and GIS modeling integrated with field survey for mapping mosquito breeding sites and the areas under risk of diseases transmission in El-Fayoum governorate. Entomological surveys were conducted for a total number of 40 accessible breeding sites during the period 12-16 November 2017. A calibrated Landsat OLI image, synchronized with the field trip, was processed to produce Normalized Difference Vegetation Index (NDVI), Normalized Difference Moisture Index (NDMI), and Land Surface Temperature (LST). A cartographic GIS model was generated to predict breeding sites in the whole governorate and to assess the potential risk. The main filarial disease vector (Culex pipiens) was abundant at Atsa district, while Malaria vectors (Anopheles sergentii and Anopheles multicolor) were mainly distributed in El-Fayoum and Youssef El-Seddiq districts. Means levels of NDVI, NDMI and LST at breeding habitats were recorded; 0.18, 0.08 and 21.75° C, respectively. Results of the model showed that the highest predicted risk area was reported at Atsa district (94.4 km2) and Yousef El-Sediq (81.8 km2) while the lowest prediction was observed at Abshawai district (35.9 km2). It can be concluded that Atsa, Yousef El-Sedik and El-Fayoum districts are more vulnerable to Malaria and Filaria diseases outbreaks, thus precaution and pest control methods must be applied to mitigate the possible risks.

“…The approach used in this study is similar to that used by other researchers (Sathees et al, 2020;El-Zeiny & Elbeih, 2019;Francis et al, 2020;Gebrehiwot et al, 2011;Gorai & Kumar, 2013;Jha et al, 2015;El Mountassir et al, 2020;Muzenda et al, 2019;Pradhan et al, 2001;Rabeiy, 2017;Ramachandran et al, 2020;Saeedi & Sharifi, 2010;Talebiniya et al, 2019;Re et al, 2013) The computed WQI values are classified into five types, "excellent water" to "water, unsuitable for drinking" shown in Table 2.…”

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.
