      abstract     = {Wind erosion is a serious environmental threat. However,
                      for Northern Africa estimates or predictions of the wind
                      erodible fraction (WEF) in arid soils are rare. This study
                      was conducted to (i) compare the flat sieve (WEFfs) and the
                      Fryrear equation (WEFc) in order to estimate WEF (ii) fuse
                      the directly measured WEFfs values to other measured soil
                      parameters, i.e. soil organic matter (SOM), carbonate
                      (CaCO3), sand, silt and clay content, to obtain a new
                      improved WEF equation prediction. Samples were collected at
                      ten locations near Gabès (Southern Tunisia) at three depths
                      (0–2.5, 2.5–5 and 5–15 cm) in cultivated or native
                      soils.The obtained WEFfs $were>80\%$ and therefore the soils
                      would be classified as highly wind erodible
                      $(WEF > 50\%).$ The lowest WEFfs values were found in the
                      cultivated soils $(82.5\%),$ ranging from 82.5 to $96.9\%.$
                      Our WEFfs estimates were positively correlated to sand
                      (r = 0.78; p < 0.001), but negatively correlated to
                      CaCO3 content (r = -0.82; p < 0.001). Interestingly,
                      neither SOM nor clay content was strongly related to WEFfs.
                      However, the WEFfs in cultivated soils was significantly
                      linked to ∑(SOM + clay content). The Fryrear estimation
                      predicted all WEFc values to be less than $60\%.$ This clear
                      mismatch to our data relates to CaCO3 presence, high sand
                      and low SOM content in our Tunisian soils, when compared to
                      US soils used to establish the Fryrear method. Therefore, we
                      established a new equation for the wind erodible fraction,
                      WEFmod $(\%) = 125.83–0.59*Clay(\%)$ − $0.22*Silt(\%)$
                      − $0.25*Sand(\%) + 0.29*SOM(\%)$ $−0.69*CaCO3(\%)$
                      (r = 0.85; p < 0.001). In the studied regions of
                      Tunisia, this equation predicts much better soil WEF. The
                      present paper is a first study to improve WEF estimation and
                      prediction in arid North Africa. Better predictions of WEF
                      are crucial in combating wind erosion of soils both in North
                      Africa and in comparable soils globally.},
