Current Insights into the Effectiveness of Riparian Management, Attainment of Multiple Benefits, and Potential Technical Enhancements

Abstract: Buffer strips between land and waters are widely applied measures in diffuse pollution management, with desired outcomes across other factors. There remains a need for evidence of pollution mitigation and wider habitat and societal benefits across scales. This paper synthesizes a collection of 16 new primary studies and review papers to provide the latest insights into riparian management. We focus on the following areas: (i) diffuse pollution removal efficiency of conventional and saturated buffer strips, (ii… Show more

“…Regular biomass harvesting may represent a suitable management measure to counteract this accumulation of P, which is able to deplete DPS in topsoil of the buffer strips over time (Hille et al, 2019). Furthermore, not only does the harvested biomass remove surplus P; it could be of further value (i.e., as natural fertilizer or raw material for bioenergy production), which would also cover part of the harvesting costs (Stutter et al, 2019). …”

“…The retention of dissolved P in buffer strips decreases when available sorption sites (as represented by the P sorption capacity, PSC) become saturated, which is expressed by the degree of phosphorus saturation (DPS) (Berg et al, 2006; Breeuwsma and Silva, 1992; De Smet et al, 1995). Hence, a high DPS increases the risk that dissolved Pi will be transferred into adjacent watercourses and raises concerns that buffer strips will become a future source of P (Stutter et al, 2019). In addition, dissolved P and PP originating from farmland can be directly transported into watercourses during pronounced rainfall events when retention by buffer strips is reduced (Roberts et al, 2012).…”

“…There is a risk that the political push towards a bioeconomy may cause riparian zones and other marginal lands to be more intensively utilised for fuel, fodder and food. At the same time, natural riparian zones can be highly useful in keeping soil particles, nutrients and other pollutants from entering the water bodies and thus should be protected and maintained in areas of intensive agriculture (Stutter et al 2019). Restoring and maintaining natural vegetation in riparian zones will provide buffer zones where nutrients can infiltrate in the soil and be used by the terrestrial vegetation, and thereby reduce losses to the water bodies (Turunen et al 2019).…”

“…Additionally, riparian vegetation can provide a source of organic matter to boost in-stream denitrification [108], as well as shading to regulate in-stream temperature and nuisance plant biomass [122,123], thereby mitigating in-stream eutrophication and responses to it [124,125]. Although riparian buffer N management approaches have become increasingly sophisticated to address multiple contaminants and provide ecological benefits to waterways [86], enhancing riparian vegetation alone may not be enough to attenuate catchment N in situations with legacy N from groundwater [39,126] or stream sediments [91], or where subsurface tile drains or seepage zones bypass riparian buffers [37,127]. Thus, to address these challenges, contemporary riparian buffer management aims to restore structural components and functions associated with saturated soils and multiple vegetation types, and enhance processing with 'treatment train' components like bunds, wetlands, and intercepting subsurface drainage [86,128].…”

In contrast, combinations of multiple in-stream N attenuation tools such as two-stage channels, low-grade weirs, or in-stream bioreactors are far less common [104].…”
