Factors Influencing Soil Erosion Control Practices Adoption in Centre of the Republic of Benin: Use of Multinomial Logistic

Water erosion threatens large agricultural areas in Benin. This study dealing with the effect of personal household’s attributes and field physical characteristics on erosion control practices was carried out in the watershed of Zou. A total of 390 farmers distributed in six were randomly sampled. Questionnaires, interview, focus group discussion and field observation were used as the main data collection technics. It allowed to collect sociodemographic and institutional characteristics and have a view on the effectiveness of the erosion control practices adoption. The data were analyzed using descriptive statistic and logistic regression. Ridging parallel to the slope (40.77% in adoption); mulching (11.03% in adoption); isohypse ridging (16.67% in adoption) and no-tillage (8.46 in adoption) were inventoried as soil erosion control practices on the watershed. It appears that that the household’s sociodemographic and institutional attributes and field physical characteristics significantly affected the adoption of the inventoried water erosion control practices. Sex, education, farmer’s organization membership, landownerships, access to agricultural advice service, position of the field on the toposequence and presence of water stream significantly influenced the soil erosion control practices adopted on the watershed. The results of this study showing that set of factor sway farmers to adopt soil erosion control practices can help policy makers to upscale the adoption of the practices and soil scientists to orient their research programs on erosion control practices.

The aim of this study was to determine the suitable conservation treatments to control water erosion from skid trails in ShastKalate forests. Two longitudinal slopes of 20-40% and > 40% were considered as critical slopes for skid trails. Treatments of water diversion ruts, water diversion ruts filled with slash and stones were implemented on each slope. A rubber bar was installed at the end of the slope to convert runoff into collectors. Sampling was done during rainfall events in autumn and winter seasons. Findings indicated that the treatment of water diversion ruts filled with slash was better than the other treatments in the control of sediment and soil loss, especially in the slope class of 20–40%. In the slope class of > 40%, there was not any significant difference between treatments in sediment and soil loss control, but generally water diversion ruts filled with slash and stones were better in soil erosion control than water diversion ruts. In both slope classes, the rainfall intensity of 0.11 mm·h<sup>–1</sup> (2.64 mm in 24 h) was the threshold of soil erosion on skid trails. The control of water erosion of soil on skid trails by the operation of water diversions is a suitable treatment for conserving skid trails.

Soil Erosion Control

Soil erosion is an environmental concern that affects agriculture, wildlife and water bodies. Soil erosion can be avoided by maintaining a protective cover on the soil to create a barrier to the erosive agent or by modifying the landscape to control runoff amounts and rates. This research is focused on Sebeya catchment located in the Western Province of Rwanda. Sebeya catchment is one of the most affected areas by soil erosion hazards causing loss of crops due to the destruction of agricultural plots or riverbanks, river sedimentation and damages to the existing water treatment and hydropower plants in the downstream part of the river. The aims of this research were to assess the performance of erosion remediation measures and to propose the Best Management Practices (BMPs) for erosion control in Sebeya catchment. Using literature review, site visits, questionnaire and interviews, various erosion control measures were analyzed in terms of performance and suitability. Land slope and soil depth maps were generated using ArcGIS software. The interview results indicated that among the 22 existing soil erosion control measures, about 4.57% of farmers confirmed their existence while 95.43% expressed the need of their implementation in Sebeya catchment. Furthermore, economic constraints were found to be the main limitative factors against the implementation of soil erosion control measures in Sebeya catchment. Also, the majority of farmers suggest trainings and mobilization of a specialized technical team to assist them in implementing soil conservation measures and to generalize the application of fertilizers in the whole catchment. Finally, soil erosion control measures including agro-forestry, terraces, mulching, tree planting, contour bunds, vegetative measures for slopes and buffer zones, check dams, riverbanks stabilization were proposed and recommended to be implemented in Sebeya catchment.

The Stability

Abstract The efficacy of erosion control systems depends on preventing soil loss underneath and maintaining its integrity under the effects of the water flow. The paper presents the research results at the Colorado State University on the performance of double twisted wire mesh products, known as Reno Mattresses, used as soil erosion control systems. Mattresses were subjected to various flow conditions on a 10 m long flume placed on a soil layer. The performance against erosion was evaluated by assessing the effect of the stone motion inside the mattress combined with the condition of incipient soil erosion underneath, in relationship to the mattress thickness, the filling stone properties, and under variable hydraulic flow regimes. At the same time, confirming the stability obtained using the conventional tractive force design approach, the research results allowed to introduce a new performance limit based on incipient soil erosion underneath the revetment. Based on the research results, the authors propose to express the shear resistance of mattresses used as soil erosion control systems as a function of the filling stones’ size, uniformity, unit weight, mattress thickness, and the presence of vertical strengthening elements.
