“…This paper presents a study in which the effectiveness of three jute and coir fibre rolled erosion control systems (see Table 2), which are commercially available and widely applied worldwide, were tested under both laboratory and field conditions. No product with dense coverage (non-woven) was included, as these are not as effective in reducing run-off (Luo et al, 2013) and can produce even more run-off than bare soil (Davies et al, 2006;Mitchell et al, 2003).…”

Abstract. Vegetation cover is found to be an ideal solution to most problems of erosion on steep slopes. Biodegradable geotextiles (GTXs) have been proved to provide sufficient protection against soil loss in the period before vegetation reaches maturity, so favouring soil formation processes. In this study, 500 g m −2 jute (J500), 400 g m −2 (C400), and 700 g m −2 coir (C700) GTXs were first installed on a 9 • slope under "no-infiltration" laboratory conditions, then on a 27 • slope under natural field conditions. The impact of GTXs on run-off and soil loss was investigated to compare the performance of GTXs under different conditions. Laboratory run-off ratio (percentage portion of control plot) equalled 78, 83, and 91 %, while peak discharge ratio equalled 83, 91, and 97 % for J500, C700, and C400 respectively. In the field, a run-off ratio of 31, 62, and 79 %, and peak discharge ratio of 37, 74, and 87 % were recorded for C700, J500, and C400 respectively. All tested GTXs significantly decreased soil erosion. The greatest soil loss reduction in the field was observed for J500 (by 99.4 %), followed by C700 (by 97.9 %) and C400 (by 93.8 %). Irrespective of slope gradient or experimental condition, C400 performed with lower run-off and peak discharge reduction than J500 and C700. The performance ranking of J500 and C700 in the laboratory differed from the field, which may be explained by different slope gradients, and also by the role of soil, which was not included in the laboratory experiment.

“…During this period of high erosion risk, geotextiles or erosion control mats are a possible temporary alternative for vegetation cover and can offer immediate soil protection on steep slopes (Hann and Morgan, 2006). Preliminary investigations suggest biological geotextiles could be an effective and inexpensive soil conservation method, with enormous global potential Davies et al, 2006). Once geotextiles are installed on slopes, they remain in place for several months and integrate with the established vegetation.…”

Evaluation of biological geotextiles for reducing runoff and soil loss under various environmental conditions using laboratory and field plot data

Preliminary investigations suggest biological geotextiles could be an effective and inexpensive soil conservation method, with enormous global potential. However, limited quantitative data are available on the erosion-reducing effects of biological geotextiles. Therefore, the objective is to evaluate the effectiveness of biological geotextiles in reducing runoff and soil loss under controlled laboratory conditions and under field conditions reflecting continental, temperate and tropical environments. In laboratory experiments, interrill runoff, interrill erosion and concentrated flow erosion were simulated using various rainfall intensities, flow shear stresses and slope gradients. Field plot data on the effects of biological geotextiles on sheet and rill erosion were collected in several countries (UK, Hungary, Lithuania, South Africa, Brazil, China and Thailand) under natural rainfall. Overall, based on the field plot data, the tested biological geotextiles reduce runoff depth and soil loss rates on average by 46 per cent and 79 per cent, respectively, compared to the values for bare soil. For the field and laboratory data of all tested geotextiles combined, no significant difference in relative runoff depth between field measurements and interrill laboratory experiments is observed. However, relative soil loss rate for the concentrated flow laboratory experiments are significantly higher compared to the interrill laboratory experiments and the field plot measurements. Although this study points to some shortcomings of conducting laboratory experiments to represent true field conditions, it can be concluded that the range and the mean relative runoff depth and soil loss rate as observed with the field measurements is similar to those as observed with the interrill laboratory experiments.

Field and laboratory studies indicate that geotextile mats constructed from palm leaves are an effective, sustainable and economically viable soil conservation technique. The three-year (2005-08) EU-funded BORASSUS Project (Contract Number INCO-CT-2005-510745) is evaluating their long-term effectiveness in controlling soil erosion and assessing their sustainability and economic viability. These studies are in progress in 10 countries, both in the 'industrial north' (in Europe) and in the 'developing south' (Africa, South America and South-East Asia). This paper focuses on agro-environmental applications and potential in the 'developing south' (The Gambia, South Africa, Brazil, China, Thailand and Vietnam). Biogeotextiles offer potentially novel bioengineering solutions to environmental problems, including technologies for soil conservation, sustainable plant production and use of indigenous plants, improved ecosystem management, decreasing deforestation, improving agroforestry and cost-effective geotextile applications in diverse environments. Biogeotextiles may provide socio-economic platforms for sustainable development and the benefits for developing countries may include poverty alleviation, engagement of local people as stakeholders, employment for disadvantaged groups, small and medium enterprise (SME) development, earning hard currency, environmental education and local community involvement in land reclamation and environmental education programmes. These benefits are achieved through: (a) promotion of sustainable and environmentally-friendly palm agriculture to discourage deforestation, promoting both reforestation and agroforestry; (b) construction of palm geotextiles enabling development of a rural labour-intensive industry, particularly encouraging employment of socially-disadvantaged groups and (c) export of palm geotextiles to industrialized countries could earn hard currency for developing economies, based on the principles of fair trade. Keywords:soil and water conservation, bioengineering technology, socio-economic development. IntroductionRecent improvements have been made in soil conservation technology and over the last three decades significant advances have been made in our understanding of soil erosion mechanisms and rates under different environmental conditions. However, there have been few advances in developing innovative soil conservation techniques. Moreover, relatively little research has been conducted at the interface between soil technology and socio-economic issues in developing countries, such as sustainable development, poverty alleviation and rural employment. One technique for soil conservation is geotextiles, which can create stable, non-eroding environments that provide the time necessary for vegetation to establish and grow. If constructed from indigenous materials, geotextiles can be effective, affordable and compatible with sustainable land management strategies [1].Despite synthetic geotextiles dominating the commercial market, geotextiles constructed from org...
