Download as PPTX, PDF1 like95 views
The document discusses the outcomes from discussions on soil erosion, highlighting the need to refine assessment tools and develop a structured action plan. It addresses various types of erosion and emphasizes the importance of harmonizing data and tools for effective research and policy communication. The implementation plan outlines a phased approach for mapping soil erosion susceptibility and validating it with national data for better soil management and policy guidance.
Sum-up on Theme 1: Use of data and assessment tools in soil erosion control
- 1. Discussion outcomes from Theme 1 Nigussie Haregeweyn et al.
- 2. What was expected from the sessions of the Theme 1? 1. Refine the draft working document: Use of data and assessment tools in soil erosion and identify future actions to be taken 2. Develop time plan for future actions
- 3. Background: Synthetic workflow of the multilevel approach Water erosion Wind erosion Tillage erosion Other processes GSERmap
- 5. Key erosion-related issues covered by various presenters
- 6. Current status of Water Erosion; may need to be complimented with bottom up approach Borrelli et al. 2017, Nature Communications GloSEM
- 7. Effect of tillage erosion on soil profile truncation and soil quality, South Moravia, Czech Republik. Tillage erosion rates often exceed water erosion rates in cropland! Tillage erosion (Photo@ Poesen)
- 8. Dust storm: global problem EastSaharaWest Source: Slimani
- 9. Total soil loss due to sugar beet and potato harvesting (only) in the EU = 14 712 900 ton/harvest (period 2000-2016, Panagos et al. 2019)
- 10. Integrated approach for multiple erosion assessment (Lobb et al.)
- 11. o How we need to communicate the results for the policy makers? o Wind or water erosion? Area proportion (%) of the individual Eastern African countries subject to different levels of soil erosion severity by water and wind (SDN: Sudan; ERI: Eritrea; S-SDN: South Sudan; ETH: Ethiopia
- 12. Discussion results 1. Research needs? Set goal at various level: e.g. natural driving forces and risk map at phase 1, soil erosion risk map at phase 2 & monitoring and intervention sites at phase 3 2. Importance of erosion types depending on wider geographical coverage and availability of tools sheet and rill, gully, wind & tillage 3. Tools/ data available to calibrate and validate results of the research topic under questions? o Harmonization of tools and data sources o Global datasets for Phase 1, national datasets for phase 2 & 3 studies, use of experimental data, UVA and others as local data sources; radionuclides; trying to get access to national dataset for weather and hydrometric data
- 13. Discussion results 4. What technologies (imported and adopted and/or indigenous and measures) are available to formulate different management scenario at national scale? (collaborate with themes 2 & 3) Set indicators (soil erosion, land productivity, soil fertility…) Run different management scenarios and propose options for development interventions 5. Who will be target beneficiaries of the corresponding research results? (collaborate with theme 3) Policy makers and donors at global and national scales, farmers, local governments and development organization at local level.
- 14. Discussion results 6. How can we communicate results of soil erosion assessment to make them relevant for decision-makers? (theme 2) o To reach policy-makers at the global level, we should highlight impacts of soil erosion (carbon cycle, soil fertility, crop productivity and water quality). o Advocate for adopting soil erosion as an SDG 15.3 indicator. o Erosion risk maps and associated costs for global and national scale; land development plans and expected benefits for local level.
- 15. What is the implementation plan (GSP)? o 2019 - phase 1: after the symposium we work further on the proposed methodology. Produce the maps of susceptibility to soil erosion (top-down approach) - based on available global datasets. These maps can be used to identify hot spots and compare to national legislation on soil protection. o 2020 - phase 2: give to the countries the refined specifications and methodology for more detailed mapping on national scale, including national data on land management and land use. o phase 3: incorporating national erosion measurements for validating national maps and monitoring erosion
