Desire for greener land: Options for sustainable land management in drylands

This text intends to support people’s efforts to invest wisely in the sustainable management of land – enabling greener drylands to become a reality. Clearly laid out in a concise and well-illustrated format, it decribes the DESIRE – desertification mitigation and remediation of land – approach and the World Overview of Conservation Approaches and Technologies (WOCAT) methodology. The book includes an analysis of current degradation and sustainable land management (SLM) in DESIRE study sites, and also compiles an assessment of the SLM technologies and approaches trialled in the DESIRE project. Conclusions and policy points are presented for decision-makers, the private sector, civil society, donors and researchers

Soil Functions & Ecosystem Services

In order to fulfil RECARE’s aim to quantify in a harmonized, spatially explicit way impacts of degradation and conservation on soil functions and ecosystem services, it is important to understand the concept and review the current scientific debate. This will lay the foundation for the development and selection of appropriate methods to measure, evaluate, communicate and negotiate the services we obtain from soils with stakeholders in order to improve land management. Despite various research activities in the last decades across the world, many challenges remain to integrate the concept of ecosystem services (ES) in decision-making, and a coherent approach to assess and value ES is still lacking (de Groot et al., 2010). There are many different, often context-specific, ES frameworks with their own definitions and understanding of terms. This chapter therefore aims to identify the state of the art and knowledge gaps in order to develop an operational framework of the ES concept for the RECARE project. It will provide an overview on existing soil functions and ES frameworks and on approaches to monitor and value ES, with a special focus on soil aspects. Furthermore, it will address the question how the ES concept is operationalized in research projects and land management in Europe so far. Based on this review, the chapter concludes with a suggestion of an adapted ES framework for RECARE and on how to operationalize it for practical application in preventing and remediating degradation of soils in Europe

Soil-Improving Cropping Systems for Sustainable and Profitable Farming in Europe

Soils form the basis for agricultural production and other ecosystem services, and soil management should aim at improving their quality and resilience. Within the SoilCare project, the concept of soil-improving cropping systems (SICS) was developed as a holistic approach to facilitate the adoption of soil management that is sustainable and profitable. SICS selected with stakeholders were monitored and evaluated for environmental, sociocultural, and economic effects to determine profitability and sustainability. Monitoring results were upscaled to European level using modelling and Europe-wide data, and a mapping tool was developed to assist in selection of appropriate SICS across Europe. Furthermore, biophysical, sociocultural, economic, and policy reasons for (non)adoption were studied. Results at the plot/farm scale showed a small positive impact of SICS on environment and soil, no effect on sustainability, and small negative impacts on economic and sociocultural dimensions. Modelling showed that different SICS had different impacts across Europe-indicating the importance of understanding local dynamics in Europe-wide assessments. Work on adoption of SICS confirmed the role economic considerations play in the uptake of SICS, but also highlighted social factors such as trust. The project's results underlined the need for policies that support and enable a transition to more sustainable agricultural practices in a coherent way

Assessing impacts of soil management measures on ecosystem services

Only a few studies have quantified and measured ecosystem services (ES) specifically related to soil. To address this gap, we have developed and applied a methodology to assess changes in ecosystem services, based on measured or estimated soil property changes that were stimulated by soil management measures (e.g., mulching, terracing, no-till). We applied the ES assessment methodology in 16 case study sites across Europe representing a high diversity of soil threats and land use systems. Various prevention and remediation measures were trialled, and the changes in manageable soil and other natural capital properties were measured and quantified. An Excel tool facilitated data collection, calculation of changes in ecosystem services, and visualization of measured short-term changes and estimated long-term changes at plot level and for the wider area. With this methodology, we were able to successfully collect and compare data on the impact of land management on 15 different ecosystem services from 26 different measures. Overall, the results are positive in terms of the impacts of the trialled measures on ecosystem services, with 18 out of 26 measures having no decrease in any service at the plot level. Although methodological challenges remain, the ES assessment was shown to be a comprehensive evaluation of the impacts of the trialled measures, and also served as an input to a stakeholder valuation of ecosystem services at local and sub-national level

Harmonization of risk assessment methods of soil erosion by water in the European Union

15 páginas, 3 figuras.In order to effectively formulate mitigation strategies and implement conservation measurements to counteract soil erosion, it is essential to objectively identify and quantify areas at risk. With the adoption of the European Union (EU) Thematic Strategy for soil protection, a first step is made towards adequate measures to combat soil erosion and other soil degradation processes. However, to provide an effective tool at European level, risk assessment methodologies should be harmonized (i.e. similar although adapted to local circumstances), providing criteria and standardized definitions of risk areas within the EU. This chapter provides an overview, evaluation and assessment of risk assessment methods of water erosion currently existing and applied within the EU, in the framework of the EU-funded RAMSOIL project (www.ramsoi1.eu). Only methods with an official status andlor those that are widely scientifically acknowledged were considered and included in this review. Information on RAMs for soil erosion was identified through both questionnaires and scientific literature review. Questionnaires were sent to scientists and policy makers in EU Member States and Nonvay. The methods were compared, based on five indicators such as scale, transparency, complexity, cost efficiency and ambiguousness, after which a final statement is made about their soundness, flexibility and acceptability, reflecting the potentials for harmonization.This study was carried out under the EU-funded RAMSOIL (Risk Assessment Methodologies for Soil Threats) Project (Contract 44240).
