Defining context-specific scenarios to design vegetated buffer zones that limit pesticide transfer via surface runoff

Abstract: When used in addition to environmentally friendly cultural practices, buffer zones can limit the water transfer of pollutants, in particular pesticides, towards water resources. The choice of the buffer zones' type and positioning, considering water pathways and flow components, is crucial. When this choice has been performed, buffer zones dimensions must still be optimized, according to the environment characteristics, which strongly influence their effectiveness. This article presents a method and its associ… Show more

“…Since VFSs are commonly placed near streams and these areas can suffer seasonal shallow water conditions, this tool fills an important gap in environmental management and analysis. For example, in Europe VFSs are often prescribed along river drainage networks without objective assessment of their efficiency during winter wet periods (Carluer et al, 2017;Bach et al, 2017). In the US, the historical topography-based approach, which links priority for buffers to locations where runoff water converges from uplands and saturates the soil, often results in placement on bottomlands next to streams (Dosskey and Qiu, 2011).…”

“…Previous work studied the global sensitivity of simulated outflow, sediment, and pesticide trapping to VFS-MOD input factors (Muñoz-Carpena et al, 2007Fox et al, 2010). On the watershed scale, VFSMOD has been included in methods or frameworks to optimize filter placement and design (Dosskey et al, 2006;Tomer et al, 2009;White and Arnold, 2009;Balderacchi et al, 2016;Carluer et al, 2017). integrated VFSMOD within higher-tier, US EPA long-term pesticide exposure framework (PRZM/VFSMOD/EXAMS) to estimate changes in aquatic concentrations when VFSs are adopted as a runoff pollution control practice.…”

“…Mechanistic understanding of VFS behavior has advanced significantly in the last 20 years, and numerical simulation tools are available to analyze this important best management practice (BMP) under upland field conditions where runoff is governed by excess rainfall and field inflow processes (Muñoz-Carpena et al, 1993, 1999Abu-Zreig, 2001;Muñoz-Carpena and Parsons, 2004;Poletika et al, 2009;Sabbagh et al, 2009;Carluer et al, 2017). A recent linked mechanistic model has investigated multiple input factors and their relative importance and uncertainties on the predicted reduction of runoff, sediments, and pesticides Lambrechts et al, 2014;Muñoz-Carpena et al, 2010.…”

“…Because of the complex mechanisms and processes involved, the effectiveness of VFSs in terms of run‐off and sediment trapping usually vary greatly in the field (Dosskey, Helmers, & Eisenhauer, ; Munoz‐Carpena, Zajac, & Kuo, ; Tian, Zhang, He, & Yang, ). To guarantee the efficiency of VFSs, a field investigation must be performed regarding the design of VFSs (Carluer, Lauvernet, Noll, & Munoz‐Carpena, ; Donat, Lowry, Alexander, O'Gorman, & Maher, ). Because physically based models enhance understanding of the processes in VFSs, they are widely used as a deterministic tool in the design of VFSs (Carluer et al, ; Pan et al, ).…”
