  • Ad 1: by looking at degradation and desertification processes in an integrated wayAd 2: for qualitative and quantitative evaluation of the land degradation and desertification status
  • The methodological framework of DESIRE consists of 4 parts. Part 1 is about the socio-economic, political and environmental context of the study sites. In this part of the work flow stakeholders are identified and their goals of sustainability, and drivers of desertificiation. Status and risk of land degradation and conservation are assessed using the WOCAT-LADA expert mapping method and an independent indicator assessment (base map of land use systems and mapping questionnaire). Red box: stakeholder analysis is used.Brown and orange box: land degradation and conservation mapping using the LADA-WOCAT-DESIRE methodology is usedOrange box: statistical relationships between indicators of deseryification were used, to assess desertification risk and to analyse the effectiveness of SLM practices, to a total of 1641 observationsPart 2 is about the identification of strategies to remedy desertification, to document these, and to prioritize strategies, in all steps in collaboration with stakeholders (internal and external). The L4S and WOCAT QT/QA are used here. In the prioritization phase, a multi-criteria decision support system is used. Yellow boxes: 3-part participatory framework using WOCAT, LfS , and multicriteria evaluation. In part 3 selected strategies are trialed and monitored in the field during a period 0f 2-3 years. Stakeholders are involved in the monitoring. Strategies are assessed at site level on criteria partly corresponding to those in the WOCAT QT questionnaire, using various methods (e.g. CBA).Blue box: field-based methods including scientific and stakeholder monitoringDark blue box: PESERA and economic models (e.g. agent-based modelling, input-output modelling)Results of the local scale assessment are used as input to a coupled model framework consisting of the biophysical PESERA model and economic models (input-output, cost effectiveness, agent-based modelling). These models provide outputs at regional scales, and can be used to identify areas where different remediation strategies are most likely to be adopted by farmers and their likely biophysical impacts. The proposed grid cell size of 1 ha for the modeling work in WB5 corresponds to the field size and captures an individual farmer’s decision-making. Thus, the model essentially aggregates multiple local (adoption and biophysical) processes. Its added value consists of: i) evaluating the impacts of remediation strategies at the regional scale; and ii) evaluating the effects of policies. In part 4 of the work entails essentially the spin off of the first three parts, in that dissemination should help to get remediation strategies adopted and implemented. Dissemination will focus on target groups of land managers, national and international policy, and scientists (DESIRE being financed by DG Research). This part of part 4 is covered in DESIRE. Subsequent activities should include the monitoring of progress to goals. Based on the results of this work, remediation strategies are adjusted, or new remediation strategies may be identified and prioritised in response to changing contexts or because existing strategies are no longer needed or working. These activities should occur in follow up to the DESIRE project.

  • 2. Contents • Motivation • Objectives • Approach • Snapshots of results • Outreach LANDCON1010, October 11-15, Xián, China
  • 3. “The UNCCD is often referred to Motivation as the “African poor convention” (M. Bakharr, GEF) • Perceived lack of impact of the UNCCD on the ground • Need for scientific proof of performance of SLM strategies • Need for communication of scientific research across and within groups in the desertification regime LANDCON1010, October 11-15, Xián, China
  • 4. DESIRE Integrated Project • Co-funded by the European Commission* (9 M€) in FP6 • 26 partners • Run-time 2007-2012 www.desire-project.eu * DG Research-Environment Programme LANDCON1010, October 11-15, Xián, China
  • 5. Objectives China (ISWC ©) 1. Give SLM measures a sound scientific basis Turkey (ESOGU ©) 2. Improve definition of indicators 3. Assess and develop promising SLM strategies with stakeholder groups Chile (INIA ©) 4. Evaluate SLM measures on regional scale 5.

  • 13. SLM Technology groups tested in DESIRE Reduced & zero tillage 2 6 Contour tillage 4 Traditional water harvesting Mulching 2 Strip cropping & barriers 5 3 Controlled grazing 1 4 Tree cropping 22 SLM technologies 57 field experiments 5 Annual cropping 13 countries Grazing Forest 10
  • 14. Green manure (dryland almond, Guadelentin, Spain) A crop grown to be ploughed into the ground to increase organic matter content, thereby improving fertility and reducing erodibility
  • 15. Prescribed fire (extensive grazing, Góis, Portugal) Controlled burn to reduce fuel build-up and decrease the likelihood of serious hotter fires
  • 16. No tillage (annual cropping, Chile) No tillage machine Seeding crops without disturbing the soil through tillage, involving one pass during which a part of the soil surface is “opened” and the seeds are placed concurrently
  • 17. Rangeland resting (grazing, Tunisia) Land closed by fencing (or other means) for control of grazing or resting during a specified period to reconstitute its plant cover
  • 18. Snapshots of results • Biophysical PESERA model adapted to simulate effects of SLM technologies • Socio-economic DESMICE model developed to – assess regional effects of local SLM techs – identify areas of intervention
