Parameterization of the Effect of Bench Terraces on Runoff and Sediment Yield by Swat Modeling in a Small Semi‐arid Watershed in Northern Tunisia
No full textIn Tunisia, soil and water conservation interventions are among the most practicable strategies to prevent and mitigate rainwater losses through surface runoff and consequential erosion of fertile soils. In this study, a small and terraced agricultural catchment (Sbaihia) was used as an experimental site to analyze and parameterize the effects of bench terraces on water and sediment yield using the Soil and Water Assessment Tool. Model calibration and validation was performed, taking advantage from high-quality daily runoff data from 1994 to 2000 and a high-resolution bathymetric survey of the hill lake at the watershed outlet. Soil and Water Assessment Tool indicated that the local terraces, established on approximately 50% of the watershed area, reduced surface runoff by around 19% and sediment yield by around 22%, decelerating the siltation of the hill lake. Targeted model calibration delivered concise parameter set describing bench terrace impacts on runoff (Soil Conservation Service curve number method) and sediment yield (Modified Universal Soil Loss Equation) crucial for outscaling of soil and water conservation impacts and suitable watershed management
User-friendly and Integrated Simulation Tool for Support Sustainable Land Management Planning in Tunisian Landscape
No full textExpanding soil and water conservation (SWC) practices faces decision-making problems that are mainly caused by diversities of the environment and stakehold-er needs/preferences, as well as difficulties in anticipating planning outcomes. This study applies Integrated LAnd Management Planning Tool (iLAMPT) to examine possible management pathways to address potential soil erosion and costs-benefits driven from different sustainable land management planning sce-narios across the Rmel catchment in Tunisia. iLAMPT is an end-user oriented, spatially explicit modeling tool based on the Revised Universal Soil Loss Equa-tion (RUSLE) adjusted for the sediment delivery ratio (SDR). Different databases and field characterization were used to calibrate the model for the Rmel catchment and validate model outputs at the catchment scale. The tool also has user-friendly interfaces that helped integrate users’ preferences. The tool is meant to integrate expert-knowledge into the defining of SWC planning scenarios and related likely impact. A participatory grid-based appraisal was applied to validate the simulated spatial patterns of soil erosion at the catchment level. The first evaluation showed fairly good matching in erosion hotspots. Since the tool allows end-users define planning scenarios/options and provide outputs in a spatially explicit and timely responsive way, it assists effective discussions over landscape planning where land degradation neutrality is the ultimate goal
User-friendly and Integrated Simulation Tool for Support Sustainable Land Management Planning in Tunisian Landscape. Working paper (accepted for the Springer Nature
No full textSustainable land management (SLM) at scale is essential for achieving land degradation neutrality and improving agricultural livelihoods. In practice, promoting SLM at watershed scale faces many decision-making problems that are mainly caused by diversities of the environment and stakeholder needs/preferences, as well as difficulties in anticipating planning outcomes. This study applies (Integrated LAnd Management Planning Tool (iLAMPT) to examine possible management pathways to address potential soil erosion and costs-benefits driven from different sustainable land management planning scenarios across the Rmel catchment in Tunisia

National preparatory workshop in Tunisia
No full textThe living lab approach underlying LANDSUPPORT activities is aimed at involving policy and decision makers and potential users from the very beginning and throughout all project phases, ensuring that the delivered DSS tools can actually be used.
With this aim preparatory workshops bringing together policy makers in land management have been planned at EU/national/regional/local level. The outcomes of national and local workshops will feed into the EU workshop in order to ensure that local and national instances are brought forward at the EU level.
Workshops have been conducted at two levels (national, regional) in Italy, Austria, and Hungary. In the case of Tunisia one unified workshop has been planned at the national level, also involving stakeholders from the study site region (Zaghouan Governorate). The key focus of the workshop was on understanding the elements that decision-makers take into account when they take decisions on land use management, thus verifying the assumptions behind the LANDSUPPORT tool
First Technical Meeting - A Rmel Watershed Study Site Stakeholder Workshop, LANSUPPORT Project
No full textThe living lab approach underlying LANDSUPPORT activities is aimed at involving policy and decision makers and potential users from the very beginning and throughout all project phases, ensuring that the delivered DSS tools can actually be used. The second stakeholder workshop of the project (component in Tunisia) was held in Zaghouan on the 10th of December. The objectives of this workshop were to present the project progress, to disseminate information to the various departments of the CRDA, and to discuss at the work plan for the future activities that will be held in 2020. The workshop activities included presentations from other projects that are ongoing in the governorate of Zaghouan with the involvement of ICARDA and various Tunisian research institutions, in order to promote synergies among them. There were 35 participants, including decision makers on water and soil conservation, the different regional departments of the CRDA, researchers from INRGREF and INRAT, and the ICARDA country coordinator for Tunisia
Assessing Soil Erosion Hazards Using Land-Use Change and Rill Erosion Frequency Ratio Method: Case Study of Rmel Watershed, Northern Tunisia
No full textThis study aims to identify the vulnerable landscape areas using rill erosion frequency ratio and land-use change associated soil erosion hazard by employing geo-informatics techniques and the revised universal soil loss equation (RUSLE) model. Required datasets were collected from multiple sources, such as multi-temporal Landsat images, soil data, rainfall data, land-use land-cover (LULC) maps, topographic maps, and details of the zones affected by rill erosion. Landsat satellite images from 2000, 2010, and 2020 were used to assess the land-use change. Geospatial input data on rainfall, soil type, terrain characteristics, and land cover
19 were employed for soil erosion hazard classification and mapping. Landscape vulnerability was examined on the basis of land-use change, erosion hazard class, and rill ersion frequency ratio. Then the erodible hazard areas were identified and prioritized at the scale of the watershed

This presentation comes under the second session “Evaluations of impacts of SWC planning scenarios on soil erosion across Rmel watershed” of the workshop "Systems Tool-aided Participatory Development of Sustainable Land Management Scenarios: 2nd Workshop", held in Zaghouan on 14-15 March 2017. This activity is under the output activity "User-friendly, interoperable online tool, containing country-specific, accessible knowledge base of standardized, geo-referenced SLM, to enable stakeholders to query SLM options in different context" of the GIZ funded project “Impact evaluation of SLM options to achieve land degradation neutrality”
