    • Implementation process Measurable & Visible results• Appraiser estimations showed that fields under SLM practice resulted with a minor impact of soil erosion - down to 90% reduction comparing conventional tillage.• Infiltration rates in SLM interface areas were significantly higher comparing conventional tillage.• Aggregate stability in SLM areas that treated at minimum-tillage with organic manure and compost was significantly high comparing conventional tillage. 2nd Scientific Conference UNCCD

    • Policy constructionIn order to avoid further land degradation, due to inappropriateinterface, 2 routes of recommendations were taken: 1. Implementation of enhanced SLM interface that include the following phases: I. Constructing, with farmers, a mutual workplan where a long-term treaty was signed, among all partners who were whiling to join this action, based on watershed management plan. II. Building of regional steering committee that will guide and direct the necessary stages toward SLM. III. Development of subsidizing tools, as well as compensation and penalties, to urge SLM actions toward the desired route. IV. Construction of SLM guidance system that provide farmers and stakeholders enhanced tools and supervision when and where SLM actions are taken.2. Support and partially subsidize farmers who are whiling to initiate SLM acts. 2nd Scientific Conference UNCCD
    • Conclusions• Demonstration of an extreme soil erosion event and its impact on the environment led to rising awareness of SLM.• Following all implementation actions, additional farmers had exposed to this approach and nowadays, the Valley region is promoting SLM over additional regions of the country.• Promoting agro-technical practices were found effective, at the threshold of 80% subsidize, while farmers are obliged by the signed treaty.• Encouraging farmers to take agronomical conservation actions as cover crops, monitoring grazing pressure etc. showed that runoff and erosion impact reduced significantly.• However, although SLM was found effective, we have other difficulties: • SLM is multi-disciplinary approach thus make it difficult to implement. • financing SLM actions is a limiting factor, while the demand for subsidize increases; lacking of SLM standardization. 2nd Scientific Conference UNCCD
