“…This results in a river discharge reduction such as was demonstrated in the Central Spanish Pyrenees by Beguería et al [56] or in Slovenia where the Dragonja River reduced the sediment delivery due to the loss of the runoff discharge as a consequence of the natural afforestation [57]. The use of water by the vegetation (transpiration) also resulted in the loss of water available by plants such as Moreira et al [58] found in the Amazon on abandoned pastures, Rambousková et al [59] in the abandoned fields in the Bohemian Karst, and Farrick and Price [60] in the Sphagnum restoration in peatlands.…”

Due to the reduction in the prices of oranges on the market and social changes such as the ageing of the population, traditional orange plantation abandonment in the Mediterranean is taking place. Previous research on land abandonment impact on soil and water resources has focused on rainfed agriculture abandonment, but there is no research on irrigated land abandonment. In the Valencia Region—the largest producer of oranges in Europe—abandonment is resulting in a quick vegetation recovery and changes in soil properties, and then in water erosion. Therefore, we performed rainfall simulation experiments (0.28 m2; 38.8 mm h−1) to determine the soil losses in naveline orange plantations with different ages of abandonment (1, 2, 3, 5, 7 and 10 years of abandonment) which will allow for an understanding of the temporal changes in soil and water losses after abandonment. Moreover, these results were also compared with an active plantation (0). The results show that the soils of the active orange plantations have higher runoff discharges and higher erosion rates due to the use of herbicides than the plots after abandonment. Once the soil is abandoned for one year, the plant recovery reaches 33% of the cover and the erosion rate drops one order of magnitude. This is related to the delay in the runoff generation and the increase in infiltration rates. After 2, 3, 5, 7 and 10 years, the soil reduced bulk density, increase in organic matter, plant cover, and soil erosion rates were found negligible. We conclude that the abandonment of orange plantations reduces soil and water losses and can serve as a nature-based solution to restore the soil services, goods, and resources. The reduction in the soil losses was exponential (from 607.4 g m−2 in the active plot to 7.1 g m−2 in the 10-year abandoned one) but the water losses were linear (from 77.2 in active plantations till 12.8% in the 10-year abandoned ones).

“…We found a general linear relationship between PLRC and RWC at dehydration. Whereas most studies found similar trends (Alexandre, 1991;Buckley et al, 1980;Burghardt et al, 2008;Burghardt & Riederer, 2003;Goldstein et al, 1985;Hinckley et al, 1983;Kapos & Tanner, 1985;Oppenheimer, 1963;Park, 1989;Peace & Macdonald, 1981;Weinberger et al, 1972), some previous work found water content recovery to drop exponentially with leaf dehydration (Florineth, 1980;Rambousková, 1981;Rychnovska, 1967;Sommerville & Read, 2008). The linear relationship would indicate that progressive dehydration leads to damage or death of a proportional number of cells such that they cannot rehydrate to their maximum capacity (Kramer & Boyer, 1995;Oppenheimer & Leshem, 1966).…”

“…Our search for all available data in the literature for RWC@PLRC 10 , RWC@PLRC 25 , and RWC@PLRC 50 resulted in a novel global database for 89 species native to montane and lowland wet tropical forests, temperate forests, Mediterranean ecosystems, and grasslands from 17 publications (Table S7; Oppenheimer, 1963;Rychnovská-Soudková, 1963;Oppenheimer & Leshem, 1966;Rychnovska, 1967;Weinberger et al, 1972;Buckley et al, 1980;Florineth, 1980;Peace & Macdonald, 1981;Rambousková, 1981;Hinckley et al, 1983;Goldstein et al, 1985;Kapos & Tanner, 1985;Park, 1989;Alexandre, 1991;Burghardt & Riederer, 2003;Burghardt et al, 2008). The mean RWC@PLRC 10 across the California species tested in this study (65.9 ± 4.2%) was similar to that across our global database (61.4 ± 1.8%, P = 0.31; unpaired t test).…”

“…Oppenheimer associated a PLRC of 10% in Nerium oleander with loss of leaf cell viability and death as assessed by vital staining and cross‐sectional anatomy of dehydrated leaves and designated this threshold (PLRC 10 ) as the “sublethal water deficit” or “permanent turgor loss point” (Oppenheimer, ; Oppenheimer & Leshem, ). Subsequent studies of diverse ecosystems quantified this index to compare coexisting species and achieved insights regarding variation in drought tolerance within and among specific ecosystems (Table S7; Oppenheimer, ; Rychnovská‐Soudková, ; Oppenheimer & Leshem, ; Rychnovska, ; Weinberger, Romero, & Oliva, ; Buckley, Corlett, & Grubb, ; Florineth, ; Peace & Macdonald, ; Rambousková, ; Hinckley, Duhme, Hinckley, & Richter, ; Goldstein, Meinzer, & Monasterio, ; Kapos & Tanner, ; Park, ; Alexandre, ; Burghardt & Riederer, ; Burghardt, Burghardt, Gall, Rosenberger, & Riederer, ). The PLRC 10 has practical advantages over other indices of leaf dehydration tolerance, such as the visually estimated “lethal leaf water potential,” which is difficult to ascertain objectively (Augé, Duan, Croker, Witte, & Green, ; Augé, Stodola, Moore, Klingeman, & Duan, ; Brodribb, Bowman, Nichols, Delzon, & Burlett, ; Chapman & Augé, ; Kubikova, Jennifer, Bonnie, Michael, & Augé, ; Kursar et al, ).…”

Clarifying the mechanisms of leaf and whole plant drought responses is critical to predict the impacts of ongoing climate change. The loss of rehydration capacity has been used for decades as a metric of leaf dehydration tolerance but has not been compared with other aspects of drought tolerance. We refined methods for quantifying the percent loss of rehydration capacity (PLRC), and for 18 Southern California woody species, we determined the relative water content and leaf water potential at PLRC of 10%, 25%, and 50%, and, additionally, the PLRC at important stages of dehydration including stomatal closure and turgor loss. On average, PLRC of 10% occurred below turgor loss point and at similar water status to 80% decline of stomatal conductance. As hypothesized, the sensitivity to loss of leaf rehydration capacity varied across species, leaf habits, and ecosystems and correlated with other drought tolerance traits, including the turgor loss point and structural traits including leaf mass per area. A new database of PLRC for 89 species from the global literature indicated greater leaf rehydration capacity in ecosystems with lower growing season moisture availability, indicating an adaptive role of leaf cell dehydration tolerance within the complex of drought tolerance traits.
