The wetlands of northeastern Algeria are rich in flora because of their biogeographical context. The Fetzara Lake, designated Ramsar site since 2002, has been the subject of multiple plant surveys conducted between 2014 and 2019 and has revealed the existence of 226 taxa belonging to 166 genera and 58 families with the dominance of therophytes (45.13%, 102 species). From the chorological point of view, the Mediterranean type was the most dominant with 128 taxa or 56.64% of the studied flora 19 of which are endemic to Algeria. Canonical analysis represented the superimposition of the three physiognomic environments of vegetation (dry lawns, amphibian meadows and semi-permanent lake) with respect to environmental variables. The results suggest that the distribution and variation of species abundance is mainly ordered according to salinity and grazing. These degradation factors therefore merit to be divulgated to arouse awareness of the public authorities and the population in order to implement appropriate protective measures.

“…Irrigation plays a dominant role in agriculture because of degrading water resources and variant distribution of the rainfalls. Farmers need to save water and make judicious use of it, especially during the dry season [HALIMI et al 2017;ZARE et al 2014]. When the concentration of soluble Na + ions in the soil is high, these ions replace the Ca 2+ cations (basic exchanges) in the absorbing complex; this can be induced by salt-loaded water; this risk is determined by the measurement of sodium absorption ratio (SAR) [GOUAIDIA et al 2013].…”

The Hamadian groundwater table ensures water supply for the agricultural perimeter of Wadi Mehiya region in the North-East of Tindouf city. In order to determine the behaviour of this groundwater table, a piezometric map have been realized, followed by physicochemical analyses to assess the chemical facies, the suitability of this water for irrigation and drinking purposes, as well as its vulnerability to different pollutants. This groundwater table is essentially composed of fine to coarse and clayey sands, surmounted by a silicified limestone slab. It is a free groundwater table with a thickness of 18 to 99 m. The sampling has been done in June 2010. Then, the physicochemical analyses have been performed on 7 samples taken from 7 boreholes. The piezometric study proved that the flow of groundwater table follows a North-East to South-West direction, towards the Sebkha of Tindouf. The graphic representation of chemical facies, using Piper and Schoeller–Berkaloff diagrams, reveals that the water of Wadi Mehiya contains mainly magnesium sulphate. The graphical representation of irrigation water quality, using Wilcox diagram, revealed an acceptable quality with a high salinity. Moreover, this water is potable with hard-mineralized character. Nitrates contamination has been also noted, which is a logical result of the excessive use of chemical fertilizers.

“…Losing soil particles from the agricultural fields causes destruction of the soil cover, reducing its thickness and depleting its richness of fertile components and thus contributing to the deterioration of agricultural production efficiency [CHADWICK, CHEN 2002;HALIMI et al 2018;HEJ-DUK et al 2017;KOWALCZYK et al 2014;NEARING et al 2005;PÄRN, MANDER 2007;QUINTON et al 1999;SMO-ROŃ, KOWALCZYK 2012;VAGSTAD et al 2001]. This phenomenon, especially in undulating loess areas, presents a significant economic problem and causes high environ-mental degradation.…”

Research was conducted in selected points of the Szreniawa River basin (area 712 km2) located in the Miechowska Upland and the Proszowice Plateau. In the years 2016–2017 water samples from the Szreniawa River were taken monthly and the concentration of suspended solids was determined by filtration. The concentration of biogenic components NO3-N, NH4-N and PO4-P was determined by a colorimetric method, using an automatic flow analyser. The average concentration of suspended solids ranged from 192 to 390 mg·dm−3 (with minimum values of 5–20 mg·dm−3 and maximum 837–3937 mg·dm−3) at individual points. There was an upward trend between the content of suspended solids and the concentration of biogenic components. An extremely high concentration of suspended solids happened during storm-like precipitation at the end of June 2017 and amounted to 3937.2 mg·dm−3. The concentration of biogenic components was also highest in this period and amounted to 2.50 mg·dm−3 of NO3-N, 0.49 mg·dm−3 of NH4-N and 1.18 mg·dm−3 of PO4-P. At low precipitation the concentration of suspended solids was also low (5.0 mg·dm−3). A similar pattern was observed for the concentration of biogenic components which was 0.39 mg·dm−3 of NO3-N, 0.17 mg·dm−3 of PO4-P and 0.08 mg·dm−3 of NH4-N.
