    Evidence-based decision-making - Knowledge management - Land degradation neutrality - Mapping - SLM technologies and approaches - Sustainable land management

    WOCAT – The World Overview of Conservation Approaches and Technologies with its unique methodology and global Sustainable Land Management (SLM) database - can help promote scaling out of SLM and thus contribute to land degradation neutrality. This paper focuses primarily on three Land Degradation Neutrality (LDN) indicators: (i) land cover, (ii) land productivity and (iii) carbon stocks. It is demonstrated what can be achieved by analyzing SLM practices in the database and how these shed light on the LDN indicators. Different stages of interventions - from prevention (avoiding), to reduction (reducing), and restoration (reversing) of Land Degradation (LD) - are differentiated and analyzed. This highlights the fact that most efforts and achievements recorded by WOCAT focus on reducing and preventing LD: that stands in contrast to the current emphasis by many policy makers on the much more costly task of restoration. The use of the WOCAT-LADA (Land Degradation Assessment) mapping approach is illustrated, with a case study from Madagascar. Understanding and integrating mosaic pieces at the local level can help in comprehending impacts at the national and global levels as observed by remotely sensed imagery. Supporting land users with financial resources, an enabling legal framework and, in particular with knowledge and information about SLM practices is a logical and promising way forward to promoting adoption of SLM and, eventually, reaching LDN. With respect to creating an enabling environment for scaling out SLM and supporting land users, the analysis reveals that knowledge is the second greatest constraint after financial resources. This implies that further investment must be made in capacity building and sharing knowledge on impacts of SLM, costs-benefits and the spatial spread of SLM. Furthermore, this knowledge should be linked to a clear SLM mainstreaming and scaling out strategy, which will support countries to reach their LDN targets. A decision support framework was developed by the Food and Agriculture Organization of the United Nations (FAO) and WOCAT which guides countries in LD and SLM assessments, and the use of the results for formulating and informing SLM mainstreaming and scaling out.

    Recare - Preventing and remediating degradation of soils in Europe through land care
    Lynden, G. van; Ritsema, C.J. ; Hessel, R. - \ 2014
    Planet@Risk 2 (2014)S3. - ISSN 2296-8172 - p. 169 - 173.
    Much knowledge is available on soil threats in Europe, but this is fragmented and incomplete, in particular regarding the complexity and functioning of soil systems and their interaction with human activities. The main aim of the new RECARE project is to develop effective prevention, remediation and restoration (or Sustainable Land management – SLM) measures using an innovative trans-disciplinary approach in 17 case study areas across Europe, covering a range of soil threats in different bio-physical and socio-economic environments. Within these Case Study sites, i) the current state of degradation and conservation will be assessed ii) impacts of degradation and conservation on soil functions and ecosystem services will be quantified, iii) SLM measures will be selected, implemented and evaluated in a participatory process, and iv) the applicability and impact of these measures at the European level will be assessed. Existing national and EU policies will be reviewed and compared to identify potential contradictions and synergies. A comprehensive dissemination and communication strategy will serve a variety of stakeholders to stimulate renewed care for European soils
    Assessment of the status of human-induced soil degradation in South and South-East Asia (ASSOD)

    soil science
    Following publication of the World Map of the Satus of Human-induced Land Degradation (GLASOD), at scale 1:10M, the need for more detailed and more country-specific degradation assessment became apparent. In 1993, the members of the Asian Network on Problem Soils recommended the preparation of a qualitative assessment for South and Southeast Asian at a scale of 1:5 million. The assessment was ... carried out using a physiographic base map, compiled according to the SOTER methodology, and a slightly modified GLASOD methodology. The information was stored in a digital database and linked to a GIS enabling preparation of thematic outputs in the form of maps, graphs and tables. This exploratory map, in GIS format, can serve as a guide to policy-makers and decision-makers to identify broad regions of immediate concern. It can be used as input layer in studies at a global scale (< 1:5 000 000).

    Continuing soil degradation remains a serious threat to future food security. Yet, global soil degradation assessments are based on qualitative expert judgments or remotely sensed quantitative proxy values that suffice to raise awareness but are too coarse to identify appropriate sustainable land management interventions. Studies in China and Sub Saharan Africa illustrate the considerable impact of degradation on crop production but also point to the need for solutions dependent on location specific agro-ecological conditions and farming systems.The development of a comprehensive approach should be feasible to better assess both extent and impact of soil degradation interlinking various scales, based on production ecological approaches and remote sensing to allow disentangling natural and human induced causes of degradation. A shared common knowledge base cataloguing hard-won location-specific interventions is needed for successfully preventing or mitigating degradation
    Mapping the impact of SLM - the WOCAT - DESIRE experience
    Lynden, G.W.J. van; Verzandvoort, S.J.E. ; Schwilch, G. ; Liniger, H.P. - \ 2012
    ABSTRACT Since 1992, the World Overview of Conservation Approaches and Technologies (WOCAT) initiative has developed a standardized method for documentation of Sustainable Land Management (SLM) practices. The resulting on-line database currently counts over 450 technologies and over 350 approaches (implementation strategies) from around 50 countries. WOCAT also developed a tool to map land degradation and conservation. This method complements the information provided by the individual case studies on technologies and approaches. It evaluates what land degradation is occurring where and what is done about. The challenge is now to implement SLM practices that address environmental, economic and social concerns, i.e. decreasing degradation and improving ecosystems, while enhancing agricultural productivity and the livelihoods of land users. Research to show and quantify these impacts of SLM practices and on implementation strategies is undertaken in projects like DESIRE, in which the WOCAT methods and tools were used and further developed, from which results are presented herewith. These showed that land degradation mainly occurred as water erosion on cultivated and mixed land use. Degradation was increasing in most sites, primarily caused by inappropriate soil management. Indirectly, population pressure, insecure land tenure, and poverty appeared to be major causes of degradation. Land degradation negatively affected ecosystem services for almost all degraded areas. High negative impacts were observed regarding regulation of ecosystem services indicating that these require particular attention when developing and implementing remediation strategies. SLM measures appeared most effective on cultivated land, but positive impacts were also recorded for relatively large areas of forest and grazing land. Combinations of SLM measures appeared to perform better than single measures. Overall, there appears to be scope for improving SLM contributions to ecosystem services in cultivated land.

    degradation - desertification - participation - system
    Although sustainable land management (SLM) is widely promoted to prevent and mitigate land degradation and desertification, its monitoring and assessment (M&A) has received much less attention. This paper compiles methodological approaches which to date have been little reported in the literature. It draws lessons from these experiences and identifies common elements and future pathways as a basis for a global approach. The paper starts with local level methods where the World Overview of Conservation Approaches and Technologies (WOCAT) framework catalogues SLM case studies. This tool has been included in the local level assessment of Land Degradation Assessment in Drylands (LADA) and in the EU-DESIRE project. Complementary site-based approaches can enhance an ecological process-based understanding of SLM variation. At national and sub-national levels, a joint WOCAT/LADA/DESIRE spatial assessment based on land use systems identifies the status and trends of degradation and SLM, including causes, drivers and impacts on ecosystem services. Expert consultation is combined with scientific evidence and enhanced where necessary with secondary data and indicator databases. At the global level, the Global Environment Facility (GEF) knowledge from the land (KM:Land) initiative uses indicators to demonstrate impacts of SLM investments. Key lessons learnt include the need for a multi-scale approach, making use of common indicators and a variety of information sources, including scientific data and local knowledge through participatory methods. Methodological consistencies allow cross-scale analyses, and findings are analysed and documented for use by decision-makers at various levels. Effective M&A of SLM [e.g. for United Nations Convention to Combat Desertification (UNCCD)] requires a comprehensive methodological framework agreed by the major players
