Status of land degradation, sustainable land management and risk WOCAT maps on degree of land degradation and on land conservation measures. Status of land degradation, sustainable land management and risk Two results from the use of the WOCAT mapping methodology are presented above. 150 indicator questionnaires were completed, 30 for each of the land uses settlement, forest, orchard, grazing land and cropland. The expert system to estimate desertification risk based on indicators was applied using data collected in the indicator questionnaire and also using data from the WOCAT mapping questionnaire. Desertification risk due to water erosion in the Kelaigou study site, China Source: AUA, Greece Case study of the DESIRE methodology – Yan River Basin, China DESIRE – WOCAT 2012 Distribution of estimated desertification risk Study site Distribution of land desertification risk classes (%) No risk Slight Moderate High Very high Yan River Basin, Loess Plateau, China 22.8 21.7 16.5 21.3 17.7 261
II Identifying, evaluating and selecting SLM strategies Identify, document and evaluate SLM options The first stakeholder workshop gave the following main results. Separate evaluations of SLM technologies were performed by local and external stakeholders. Below the assessment made by the local stakeholders: Examples of potential SLM technologies for the China study site identified by local stakeholders Technology / approach Interview to complete the WOCAT questionnaire. 262 Already applied or potential solution? On land use type Labour required (initial and maintenance) Costs (initial and maintenance) Effectiveness (long-term) Limiting factors / constraints The following technologies were selected to be evaluated: 1. Planting trees, 2. Building dam, 3. Building terraced field, 4. Closure against grazing and 5. Interplanting. The WOCAT SLM technology description of the progressive bench terrace is described in this book. Prioritise and select remediation options Overall potential for local context Building dam applied cropland high high + funds are limited hard but beneficial Building terraces applied cropland high high ++ much funds and labour needed good Planting trees applied forest medium medium ++ survival of trees good Closed for grazing applied grazing low low + education level good Interplanting applied cropland low low + soil fertility good but takes more effort Protection of dryland farming areas Wang Fei In the second stakeholder workshop the main technologies selected earlier were considered, as well as a few new ones from the WOCAT database. Criteria were defined to evaluate the technologies with respect to economics/production, ecology and socio-cultural issues. Two groups of stakeholders, local or external participants, performed the evaluation. The final score represents the average of the scores of different stakeholder groups. The scoring of options is shown in the table below for some of the criteria. The results were entered into the Facilitator software. Criteria for the evaluation of SLM options in the China study site selected by stakeholders Economic / production Ecological Socio-cultural cost effectiveness effectiveness in reducing runoff reduce conflicts over water Increase yield reduce evaporation suitability for smallholders little financial inputs required for maintenance reduce siltation downstream no increase of woman workload resilience to hazards improve drinking water quantity and quality — DESIRE – WOCAT Desire for Greener Land
