“…Childhood engagement with nature acts as a bridge to environmental knowledge and behaviour later in life (Wells & Lekies, 2006;Swanwick, 2009). Our findings support the idea that the conservation of biodiversity is dependent on the social values attached to it (Harrison et al, 2014) and the success of conservation efforts depends on a good understanding of local perceptions (Demnati, Allache, Ernoul & Samraoui, 2012).…”

Algerian cities have experienced rampant urbanization for several years; this growth often occurs at the expense of natural habitats. Here, we present the results of the first census using a questionnaire focused on an urban pond in order to investigate the biodiversity perceptions in local attitudes, knowledge, and values. Our study reveals a general lack of understanding of biodiversity and ecosystem services, which may mislead local citizens to disconnect biodiversity from utilitarian or hedonic values. Furthermore, a large proportion of respondents perceived the wetlands as a nuisance. Equally important, the results among respondents indicate a significant gender bias due to a narrower window of opportunities (education, jobs, etc.) available to women than that which is available to men. The results point to an urgent need to implement policies aimed at inequality reduction and welfare improvement. Our study needs replication across the region, and its results should inform decision-makers in designing relevant policies associated with urban planning, investment in human capital, environmental education in school curricula, and the empowerment of women.

“…Arid regions are facing numerous challenges in managing limited water resources [1,2]. Although rainfall is considered one of the most crucial elements for a wide range of socio-economic activities in this harsh environment [3], extreme precipitation often leads to devastating flash floods [2,4]. Costa [5] reported that arid and semi-arid regions are susceptible to greater rainfall intensity leading to severe floods more than humid regions.…”

Assessment of Satellite-Based Precipitation Measurement Products over the Hot Desert Climate of Egypt

2019

The performance of three satellite-based high-resolution gridded rainfall datasets, namely the gauge corrected Global Satellite Mapping of Precipitation (GSMaP), Integrated Multi-Satellite Retrievals for Global Precipitation Measurement (IMERG), and the Climate Hazards Group InfraRed Precipitation with Stations (CHIRPS) in the hot desert climate of Egypt were assessed. Seven statistical indices including four categorical indices were used to assess the capability of the products in estimating the daily rainfall amounts and detecting the occurrences of rainfall under different intensity classes from March 2014 to May 2018. Although the products were gauge-corrected, none of them showed a consistent performance, and thus could not be titled as the best or worst performing product over Egypt. The CHIRPS was found to be the best product in estimating rainfall amounts when all rainfall events were considered and IMERG was found as the worst. However, IMERG was better at detecting the occurrence of rainfall than CHIRPS. For heavy rainfall events, IMERG was better at the majority of the stations in terms of the Kling–Gupta efficiency index (−0.34) and skill-score (0.33). The IMERG was able to show the spatial variability of rainfall during the recent big flash flood event that hit Northern Egypt. The study indicates that accurate estimation of rainfall in the hot desert climate using satellite sensors remains a challenge.

“…Wetland ecosystems not only represent biodiversity hotspots (Myers et al, 2001) but also provide many ecosystem services to society and the biosphere such as maintenance and improvement of water quality and protein production (Brander et al, 2006), their role in biogeochemical cycles (Reddy & DeLaune, 2008;Köchy et al, 2015;Mitsch & Gosselink, 2015;Ping et al, 2015), contribution of the agricultural livestock and salt production for local and national populations (Demnati et al, 2012;Nabahungu & Visser, 2013), regulation of hydrological regimes by storing water during droughts and retention of groundwater (Williams, 1993) or even the regulation of the local and global climates (Brevik & Homburg, 2004;Reddy & DeLaune, 2008;Argaman et al, 2012).…”

A Pedological Characterisation of Some Inland Wetlands and Ramsar Sites in Algeria

et al. 2015

This paper aims to characterise soils of 12 wetlands, of which ten are Ramsar sites, in the ecocomplex of wetlands of the Hauts Plateaux region in Northeast Algeria. Soil samples from every site were collected following the four cardinal directions, along a transect covering the peripheral vegetation belts, and from two depths of the surface horizon. Each soil sample was analysed to determine electrical conductivity, pH, total carbonates, gypsum, chlorides, bicarbonates, sulfates and the particle size. The soil texture and chemical facies (Cl-SO 4 -HCO 3 ) of each site were identified and discussed. Changes in physicochemical parameters were tested according to the spatial features of sites (orientations, vegetation transects and sample depth). A great heterogeneity was found between soils of sampled sites. Indeed, soil physicochemical characteristics differed from one site to another and between belts of the natural vegetation within the same site. Overall, the study wetlands were characterised by salty to very salty soils (electrical conductivity = 3·46 ± 2·44 dS m À1 ), of neutral to alkaline pH (6·9-8·1), moderately calcareous (CaCO 3 ranged between 15·7% and 33·7%) and little to extremely gypsiferous (gypsium varied from 2·1% to 39·4%). The dominant soil texture classes were medium textures (loam, sandy loam or silty clay loam). Chemically, chlorides (18·5 ± 16·3 Meq/100 g) and/or sulfates (16·5 ± 12·5 Meq/100 g) dominated soil solutions of these environments but with slight bicarbonate contents (0·6 ± 2·6 Meq/100 g). Moreover, there were poor correlations between physicochemical parameters, which indicates interactions between certain parameters under the effect of specific habitat conditions.
