“…Throughout this process, it will consume a great deal of the PET (Kalthoff et al, 2006). Therefore, the ''fog drip'' precipitation in forests will greatly reduce PET (Beysens et al, 2007). These findings agree with the complementary relationship between ET and PET (Xu and Singh, 2005).…”

a b s t r a c tDuring the past few decades, China has implemented several large-scale forestation programs that have increased forest cover from 16.0% in the 1980s to 20.4% in 2009. In northern China, water is the most sensitive and limiting ecological factor. Understanding the dynamic interactions between forest ecosystems and water in different regions is essential for maximizing forest ecosystem services. We examined forest cover and runoff relationships in northern China using published data from a variety of sources. In the Loess Plateau region, forest cover is not correlated with annual precipitation (r = 0.08, p > 0.05) at micro (<50 km 2 ) and meso scales (50-1000 km 2 ), while they are positively correlated at macro (>1000 km 2 ) scale (r = 0.77, p < 0.05). Moreover, forest cover is negatively correlated with the runoff coefficient (r = À0.64, p < 0.05). In Northwest China, natural forest distribution is highly correlated with annual precipitation (r = 0.48, p < 0.05) but not with the runoff coefficient (r = À0.09, p > 0.05). In Northeast China, we found a positive relationship between forest cover and the runoff coefficient (r = 0.77, p < 0.05), but the correlation between forest cover and precipitation was not significant (r = 0.28, p > 0.05). The multiple stepwise regression analysis indicated that runoff was influenced by altitude, annual precipitation, forest cover, and PET (potential evapotranspiration) in Northeast China. We concluded that geographic differences could mask the true role of forests in the partitioning of rainfall into runoff and evapotranspiration (ET) in a catchment. In determining the forest-water relationship, one must consider climatic controls on ET in addition to forest cover. Forests could potentially enhance the complementary relationship between ET and PET. Therefore, a greater amount of ET in forested areas may decrease the PET on a regional scale.

“…This was the focus of many investigations, mainly by Beysens and co-workers, aiming to increase the condensing properties of the substrates, and therefore, the amounts of dew that can be obtained for potable water (Muselli et al, 2002Beysens, Ohayon, et al, 2006;Beysens et al, 2007;Sharan et al, 2007;Sharan, Clus, Muselli, & Beysens, 2011;Clus et al, 2008Clus et al, , 2009Lekouch et al, 2012). The higher the substrate emissivity, the higher the condensation rate.…”

The current review focuses on the contribution of non-rainfall water (NRW) to arid and semiarid regions (with a focus on the Negev), where NRW may provide a constant source of water that may facilitate the survival of different organisms, especially microorganisms. Factors that determine the amounts of NRW and the contribution of NRW to plants and organisms are discussed. Nevertheless, although important, significant variation exists regarding the amounts of NRW, which may stem from improper use or inherent drawbacks of some of the measurement devices. This may lead to erroneous conclusions regarding the possible role played by NRW. For instance, with prokaryotes (bacteria and cyanobacteria) requiring liquid water (≥0.1 mm) for growth, small inaccuracies in NRW around this threshold may either lead to the conclusion that NRW is sufficiently high to facilitate their growth, or rather, is too low to facilitate their growth. Arguing that some of the devices used to measure NRW may greatly overestimate the amounts, the possible contribution of NRW to soil bacteria and cyanobacterial biocrusts is analysed. We suggest that although NRW may assist the growth and survival of mosses and some types of lichens (mostly non-crustose), no conclusive findings were thus far reported regarding the use of dew for cyanobacteria growth. The use of dew by cyanobacterial crust for growth should be critically examined, and the possibility that NRW may even result in a negative carbon balance for cyanobacterial crusts should be considered.

“…Besides, its chemical properties make dew fully suitable for human consumption (Lekouch et al, 2010;Sharan et al, 2011). Techniques aimed at collecting water from the atmosphere could serve as a complementary water source in regions such as semiarid, arid and small islands where water accessibility is difficult and supply is expensive (Muselli et al, 2006;Beysens et al, 2007;Sharan et al, 2007). Estimating and quantifying the potential of dew collection under specific climatic conditions, using different harvesting techniques and physical models to predict the potential of dew collection are of great interest to water managers.…”
