“…The former value (74%) is similar to the efficiency of the 5-m-wide fallow vegetation windbreak (70%) described by Banzhaf et al (1992) and higher than the efficiency of surface mulching (46-64%, as mentioned earlier). This higher efficiency, compared with surface mulching, corresponded to the results in Chepil and Woodruff (1963), Siddoway et al (1965), and Bilbro and Fryrear (1994), which showed that the wind erosion controlling efficiency of standing residue was higher than that of flattened one. The trapping efficiency of the fallow band in this study (74% and 58% for annual incoming soil particles and COM, respectively) was lower than that of the 5-m-wide fallow land in Ikazaki et al (2011b,c) (93% and 97%, respectively).…”

Wind erosion is a major contributor to desertification in the Sahel. Although three effective countermeasures for wind erosion (i.e. ridging, mulching with post-harvest crop residue, and windbreaks) have been proposed, they are not practical for Sahelian farmers. Therefore, we designed a new land management practice, termed the ''Fallow Band System,'' which can be used for both controlling wind erosion and improving soil fertility and crop production. This method does not impose additional expense and labor requirements on Sahelian farmers who are economically challenged and have limited manpower. The objective of this study was to evaluate the effects of this system on wind-erosion control and soil-fertility improvement. We conducted field experiments at the International Crops Research Institute for the Semi-Arid Tropics West and Central Africa and showed that (i) a fallow band can capture 74% of wind-blown soil particles and 58% of wind-blown coarse organic matter, which suggests that it can effectively control wind erosion, (ii) the amount of soil nutrients available for crops in a former fallow band was increased by the decomposition of trapped soil materials containing considerable amounts of nutrients, and (iii) the amount of soil water available for crops in a former fallow band was increased by the trapped wind-blown soil materials through improvement of rainwater infiltration into surface soil. These results lead to the conclusion that the ''Fallow Band System'' can be useful for preventing desertification and improving soil fertility in the Sahel, West Africa.

“…Early methods for modelling the impact of roughness elements on sediment mass flux focused on the establishment of empirical relations between fractional ground cover and sediment transport rates [47,[137][138][139]. During the 1990s, more attention was given to the development of drag partitioning techniques that could establish the wind momentum flux at the soil surface in the presence of roughness elements.…”

Vegetation in Drylands: Effects on Wind Flow and Aeolian Sediment Transport

Drylands are characterised by patchy vegetation, erodible surfaces and erosive aeolian processes. Empirical and modelling studies have shown that vegetation elements provide drag on the overlying airflow, thus affecting wind velocity profiles and altering erosive dynamics on desert surfaces. However, these dynamics are significantly complicated by a variety of factors, including turbulence, and vegetation porosity and pliability effects. This has resulted in some uncertainty about the effect of vegetation on sediment transport in drylands. Here, we review recent progress in our understanding of the effects of dryland vegetation on wind flow and aeolian sediment transport processes. In particular, wind transport models have played a key role in simplifying aeolian processes in partly vegetated landscapes, but a number of key uncertainties and challenges remain. We identify potential future avenues for research that would help to elucidate the roles of vegetation distribution, geometry and scale in shaping the entrainment, transport and redistribution of wind-blown material at multiple scales. Gaps in our collective knowledge must be addressed through a combination of rigorous field, wind tunnel and modelling experiments.

“…Research has shown that soil erosion decreases exponentially as a function of surface residue cover (Chepil, 1944;Siddoway et al, 1965;Fryrear, 1985) (Figure 2A). The effect is largest where residue cover increases from 0 to about 30 per cent while the surface cover factor (which approximates erosion potential) decreases from 1.0 to 0.2.…”
