ITEM 8. Towards a Global Soil Erosion Map - Lucrezia Caon, Pasquale Borrelli

  1. 1. Global Symposium on Soil Erosion Lucrezia Caon
  2. 2. “Soil erosion is defined as the removal of soil from the land surface through three major pathways: tillage, water and wind. Water erosion occurs mainly when overland flow transports soil particles detached by drop impact or runoff, often leading to clearly defined channels such as rills or gullies. Wind erosion occurs when dry, loose, bare soil is subjected to strong winds and soil particles are detached from the soil surface and transported elsewhere. Tillage erosion is the direct down-slope movement of soil by tillage implements and results in soil redistribution within a field.”
  3. 3. FAO and ITPS, 2015
  4. 4. 6th GSP Plenary Assembly 11-13 June 2018, FAO HQ, Rome
  5. 5. 2.3.3 Proposals for further global symposiums in 2019 and 2020 “The PA agreed with the proposals to organize further Global Symposiums … Therefore, it was agreed to organize the symposium on “Soil Erosion” in 2019, on “Soil Biodiversity” in 2020 and on “Sustainable soil management for nutrition‐sensitive agriculture (soil fertility)” in 2021. …”
  6. 6. Global Symposium on Soil Erosion 2019 (GSOE19) 13-17 May 2019
  7. 7. Broad objectives • A critical step toward implementing the VGSSM in terms of minimizing the soil erosion risk. • To bring science and policy together to review the status and challenges of soil erosion control. • Highlight and discuss the link between soil erosion control and the achievement of the SDGs concrete examples of effective and ineffective SSM practices, techniques, instruments and mechanisms, which would ultimately expose challenges such as scientific, technological and legislative gaps, will be provided
  8. 8. 1. Identify options to consolidate, generate and harmonize soil erosion data and assessment tools for promoting their use in decision making at all levels; 2. Review and discuss existing national and international policies, agreements and frameworks addressing soil erosion prevention, management and remediation in order to assess their effectiveness and propose ways to improve them; 3. Critically reflect on the economics of soil erosion paying attention to which SSM practices are cost effective and which others not and why, investigating options for measures that do not give a short/medium term financial benefit. 4. Advocate for an agenda for action to prevent, mitigate and monitor soil erosion Specific objectives
  9. 9. The symposia organized by the GSP are action oriented!! Symposia outputs are translated into concreate actions to implement under the framework of the Global Soil Partnership
  10. 10. Symposium’s outcomes should provide scientific and policy evidence to support decisions and actions to minimize soil erosion for increased food security, ecosystem services, and promote the restoration of eroded sites.
  11. 11. The Symposium output will be an outcome document highlighting the scientific evidence on the status of soil erosion, its impacts and an agenda for action in the framework of achieving the SDGs.
  12. 12. The document will also provide recommendations for developing sound environmental policies and programmes to encourage the use of sustainable soil erosion control practices
  13. 13. Theme 1: Use of data and assessment tools in soil erosion control This Theme will discuss ways to consolidate soil erosion data and assessment tools for the purpose of promoting their use in decision making at all levels. The baseline for developing a global soil erosion map will be discussed.
  14. 14. 1. Is there still a gap on available and reliable methods/models for assessing/mapping soil erosion? 2. What soil erosion assessment data and decision-making tools for soil erosion control are available and how can these be improved keeping into consideration the issue of inconsistencies in methods and uncertainties in results? 3. Is there a need for global assessment of soil erosion that can be the basis for a monitoring system? 4. Are dedicated information such as maps and reports concretely used in controlling soil erosion? Theme 1: Use of data and assessment tools in soil erosion control Core questions:
  15. 15. Theme 1: Use of data and assessment tools in soil erosion control Follow-up actions: - Development of a Global Soil Erosion map - What else, please suggest?
  16. 16. Theme 2: Policy in action to address soil erosion This Theme aims to review and discuss environmental policies with a focus on soil erosion prevention, management and remediation: what is missing and what can be done to assist governments in improving and/or developing their national policies? The Theme will also look into lessons learnt and the contribution that policy development and implementation could give to the achievement of the SDGs.
  17. 17. Theme 2: Policy in action to address soil erosion 3. Are the trans-national impacts of soil erosion taken into consideration in national policy development? 4. To what degree can the control of soil erosion help achieve the SDGs? Core questions: 1. Is soil erosion still an issue impeding sustainable development? If so, why? 2. Are government policies and programmes effective in advancing the implementation of soil erosion control practices by farmers and land managers? What limits the adoption of these practices by farmers and land managers? What strategies can be employed to improve adoption of these practices?
  18. 18. Follow-up actions: - Development of an online platform for national soil policy information sharing - What else, please suggest? Theme 2: Policy in action to address soil erosion
  19. 19. Theme 3: The economics of soil erosion control and restoration of eroded land This Theme links to investment and, more specifically, it aims at showing which SSM practices paid back and which others not and why.
  20. 20. Theme 3: The economics of soil erosion control and restoration of eroded land Core questions: 1. What are the associated costs of soil erosion for agriculture and development? What are the direct costs in lost crop production, the indirect costs of greater input use, and the off-site costs to the environment? 2. Are the costs of implementing soil erosion control practices offset by current and future benefits of more or more profitable production? 3. What technologies and innovations exist to decrease the costs of implementing soil erosion control practices compared to that of conventional soil management? 4. Could society compensate farmers for the public benefits (ecosystem services) from the implementation of soil erosion control practices?
  21. 21. Follow-up actions: - Writing of a booklet collecting successful and unsuccessful case studies on the practice of SSM - What else, please suggest? Theme 3: The economics of soil erosion control and restoration of eroded land
  22. 22. 2.3.3 Proposals for further global symposiums in 2019 and 2020 “…The PA appreciated the involvement of other UN organizations and panels in the preparation of these symposiums and recommended the invitation and involvement of other bodies and stakeholder institutions if suitable. ”
  23. 23. Organizers: Proposed co-organizers:
  24. 24. Theme 1: Use of data and assessment tools in soil erosion control This Theme will discuss ways to consolidate soil erosion data and assessment tools for the purpose of promoting their use in decision making at all levels. The baseline for developing a global soil erosion map will be discussed.
  25. 25. Points for reflection • Remarks on the scope of the map • Input data/Data availability • Capacity
  26. 26. Process and timeline Action/Products Deadline Obtain the mandate to produce the map by the GSP Plenary Assembly Obtained in June 2018 Concept Note - Writing - Reviewing/finalization November 2018 December 2018 GSP & Pillar 4 WG ITPS & INSII Guidelines/Technical Specifications - Development - Review/finalization February 2019 March 2019 GSP & Pillar 4 WG ITPS & INSII Appointment of national experts ASAP after March 2019 National focal points Capacity development (technical documents, online support, regional/national workshops) From April 2019 until delivery GSP Data collection and QC/QA From August to November 2019 GSP Endorsement of the GSOEMap October 2019 ITPS Launch of the Global Soil Erosion Map 5 December 2019 GSP
