“…This is a general observation (see Tables 3 and 4). A similar result was obtained in 4 countries in southern Africa by Muselli et al [36]. In addition, the timescale for mean and maximum time period between events is much larger for rain than for dew, a difference which can reach two orders of magnitudes.…”

“…Pue et al [35] introduced a Krigingbased Gaussian process for the prediction of soil water retention in tropical and temperate climates. Muselli and Beysens [36] used Kriging to study the biocrust sustainability with dew and rain availability in southern Africa. Other studies combine Kriging models for the estimation of rainfall with Lagrangian approaches [37] or Bayesian [38].…”

In the context of global warming and a reduction in fresh water availability, this study presents the evolution of dew, rain and evapotranspiration in the North-West (NW) of Africa. This study is followed by a chemical analysis of dew and rain data in a representative site. The time periods are concerned with the years 2005–2020 using existing data, and years 2020–2100 using the low and high emissions representative concentration pathway scenarios RCP 2.6/8.5 from the coordinated regional climate downscaling experiment database. A continuous decrease in rain precipitation is observed, on the order of −14 mm·decade−1 for the more credible scenario RCP 8.5. The amplitude is maximum on the coast and on the foothills of Atlas. A clear decrease in dew yields (up to 7%) is also observed along a NW/SE axis. It is strongly correlated with a corresponding decrease in relative humidity. Chemical dew and rain data in the representative site of Mirleft correspond to the major cations of Na+ > Ca2+ > Mg2+ > K+, similar to local spring water. The concentrations in rain are about two times less than in dew water. Ionic concentrations are compatible with the World Health Organization standards. The seasonal variations of the ionic concentrations in dew and rain follow a volume dilution dependence. In the future, the expected diminution in dew and rain volumes according to the RCPs 2.6 and 8.5 should increase the dew and rain ionic concentrations.
