In Pharaonic Egypt certain species were sacramented (e.g. the sacred ibis, sacred scarab, etc.) or protected as public property because of their economic importance (e.g. papyrus: material for state monopolized paper industry). In recent history laws protected certain species of animals, but protection of natural habitats with their ecological attributes and assemblages of plants and animals (nature reserves) remained beyond the interest of government. The United Nations, with the assistance of the International Union for Conservation of Nature and Natural Resources (IUCN) published lists of nature reserves worldwide, and Egypt was not mentioned in these lists till the late 1970s.

  • Environmental Sensitivity to Mosquito Transmitted Diseases in El-Fayoum Using Spatial Analyses
    E3S Web of Conferences 167, 03002 (2020) https://doi.org/10.1051/e3sconf/202016703002 ICESD 2020 Environmental sensitivity to mosquito transmitted diseases in El-Fayoum using spatial analyses Asmaa M. El-Hefni, Ahmed M. El-Zeiny*, and Hala A. Effat Environmental Studies and Land Use Division, National Authority for Remote Sensing and Space Sciences (NARSS), Cairo, Egypt Abstract. 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 21.75ₒ 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).

Riskline / Country Report / 29 August 2021 / Egypt 2 Travel Advisories Medium risk: Militant attacks in mainland Egypt Exercise caution for travel to Egypt until further notice because of potential attacks by militant groups. Domestic and international terror groups, including the Islamic State (IS), have proved that they have both the capability and intent to strike security and tourist sites within mainland Egypt, including Cairo, Giza, and 6th of October City since 2013. At least five militant attacks occurred in Cairo in 2019, killing at least 25 people and injuring 54 others. These attacks mostly targeted security forces, unlike some of the attacks from previous years, which struck places popular with tourists – including a roadside bomb attack targeting Vietnamese nationals on a tour bus near the Giza pyramids (28 December 2018), knife attacks targeting hotels and beachgoers in the resort city of Hurghada (14 July 2017 and 8 January 2016) and a suicide bombing outside Karnak Temple in Luxor (10 June 2015).

ABD EL MOITY1*, Haitham B.M. BADRAWY2, Ayat M. ALI1 1Central lab. Of organic Agriculture, Agricultural Research Center, Giza, Egypt 2Entomology Department, Faculty of Science, Ain Shams University, Abbassia, Cairo, Egypt *Corresponding author: [email protected] Abstract Quinoa, was introduced to Egypt through the few past years. According to available-data, no complete survey on pests and diseases attack quinoa in Egypt is available. The present work was designed to detect and identify diseases, and insects attack quinoa in five different Egyptian governorates (Giza, Fayium, Ismailia, Beheira and Monufia). Detection was carried out by examine different location, every 15 day and determine occurrence of diseases or pests. Data obtained showed that in all previously mentioned governorates, Rhizoctonia solani and Macrophomena phaseolina appeared as aggressive causal organism for root rot and damping off disease for young quinoa seedling. Fusarium solani was isolated only from samples were collected from Giza location. Peronospora farinosa f.sp. chenopodii was detected in all locations. This disease appeared during vegetative growth stage and before flowering or just after flowering. Insects survey was also carried out. Attacked plants were collected and transferred in ice box to laboratory for further identification. Data obtained showed that two aphid species (Myzus persicae and Aphis gossypii, Hemiptera) were detected in all location. Two pests belong also to order Hemiptera were detected in Ismailia governorate during vegetative growth and flowering stages. These two pests were identified as (Nysius cymoids) whereas the other was (Creontiades pallidus).
