With regard to protected areas, the concepts of ecosystem services and the cultural dimension of sustainable development (SD) are increasingly under debate. This contribution analyses the role of cultural aspects within the ecosystem services framework using the Millennium Ecosystem Assessment classification as a reference. The limits of the ecosystem services framework in capturing the cultural dimension are highlighted. Potential ways of strengthening the position of cultural values within this framework are discussed.

Das vorliegende Heft beinhaltet drei Vorträge der Vorlesungsreihe ‹Das Mittelmeer – Mare nostrum?›, die das Berner Mittelalterzentrum im Frühjahrssemester 2012 durchführte. Dabei wurden aus der jeweiligen Perspektive der beteiligten Disziplinen unterschiedliche Aspekte angesprochen, die in Korrelation mit diversen Begriffen standen, durch die das Mittelmeer seit der Antike bezeichnet wurde: vom ‹Großen Grün› im alten Ägypten zum ‹Mare Nostrum› in der römischen Antike, vom ‹Grossen Meer› der Juden im Mittelalter bis zum provokanten Titel ‹Corrupting Sea› in der jüngeren Forschung. Seit Fernand Braudel wurde der Mittelmeerraum als eine Einheit in der Vielfalt beschrieben. Während der französische Gelehrte Historie noch als eine Geschichte ‹ohne Namen› verstand und die kulturellen Verflechtungen, Überlagerungen und Gegensätze der nördlichen und südlichen Anrainerstaaten des Mittelmeers aus der jeweiligen landschaftlichen und geopolitischen Situation abzuleiten vermochte, neigt die jüngere Forschung dazu, diese Entwicklungen unter sozialhistorischen und anthropologischen Gesichtspunkten zu erklären, die von Menschen und deren kulturellem Austausch handeln. Eine Kulturanthropologie des Mittelmeers verschreibt sich der Aufdeckung und Analyse von Verhaltenskulturen an den Rändern kultureller Zentren. Dabei wird ‹Rand› nicht als eindimensionale Grenzlinie, sondern als Summe topographisch beschreibbarer Kulturräume jenseits staatlicher Beschränkungen verstanden. Der Beitrag von Jean-Marie Martin (CNRS, ehemals Ecole française de Rome) befasst sich unter diesem Aspekt mit der Rolle Siziliens und seiner geographischen Lage zwischen Italien und Afrika im Zeitraum von der byzantinischen zur staufischen Herrschaft. Stephan Conermann (Universität Bonn) behandelt die Mamlukenherrschaft in Ägypten und Syrien und setzt dabei Maßstäbe für eine globalgeschichtliche Betrachtungsweise. Beschlossen wird die Reihe der Beiträge von Arnold Esch (ehemals Direktor des Deutschen Historischen Instituts in Rom), der mit der ihm eigenen Kunst historischer Vergegenwärtigung eine verbindende Betrachtung der Kommunikations- und Handelswege im Mittelmeerraum des 15. Jahrhunderts leistet.

Are there differences in historical and recent upper range limits of vascular plants and are such differences more pronounced in individual species groups? The limits of 1103 plants of the Northern Alps are compared to range limits in the mid-19th century. The comparison is based on two surveys. The first survey was conducted by Otto Sendtner in 1848–1853, the second in 1991–2008 during a habitat inventory. To our knowledge this is the first comparative studies reaching back to the end of the “Little Ice Age” and comprising an almost entire regional flora covering the complete range of habitats. During the recent survey, most species were found at higher elevations. Even though the differences fit well with the expected shifts due to climate warming we cannot exclude effects of sampling bias. However, we assume that the relative differences between species groups can be safely interpreted. The differences in upper limits between both surveys were significantly larger among forest species. The most important reason is probably discontinued pasture and mowing, which may have amplified possible warming effects. Nitrogen deposits may have contributed to this effect by placing competitive species in a more advantageous position.

Im Kern des Beitrags steht die Frage, aus welchen Gründen Studierende der Soziologie einen Studienabbruch in Erwägung zu ziehen. Dabei werden drei mögliche Ursachenkomplexe fokussiert: eine mangelnde Information über das Studium, bestimmte Studienwahlmotive und die Perzeption schlechter Berufsaussichten. Im Rahmen zweier Querschnittsbefragungen an den Universitäten Dresden und Bonn werden diese Bestimmungsgründe der Studienabbruchsabsicht zusammen mit anderen Ursachen (z.B. finanzielle Probleme, mangelnde Studienmotivation etc.) simultan analysiert. Es stellt sich heraus, dass den Faktoren 'Informiertheit' und 'perzipierte Berufsaussichten für Akademiker' durchaus eine bedeutsame Rolle bei der Erklärung der Studienabbruchsabsicht zukommt, während keine direkten signifikanten Einflüsse bestimmter Studienwahlmotive nachgewiesen werden können. Gewichtigster Prädiktor der Studienabbruchabsicht ist die mangelnde Studienmotivation, die ihrerseits von einer Vielzahl der analysierten studienspezifischen Faktoren abhängt (z.B. Leistungsprobleme bei selektiven Gruppen von Soziologie-Studierenden, subjektiv eingeschätzte Dauer des Studiums).

The WOCAT network has collected, documented, and assessed more than 350 case studies on promising and good practices of SLM. Information on on- and off-site benefits of different SLM types, as well as on investment and maintenance costs is available, sometimes in quantitative and often in qualitative form. The objective of the present paper is to analyse what kind of economic benefits accrue to local stakeholders, and to better understand how these benefits compare to investment and maintenance costs. The large majority of the technologies contained in the database are perceived by land users as having positive benefits that outweigh costs in the long term. About three quarters of them also have positive or at least neutral benefits in the short term. The analysis shows that many SLM measures exist which can generate important benefits to land users, but also to other stakeholders. However, methodological issues need to be tackled and further quantitative and qualitative data are needed to better understand and support the adoption of SLM measures.

The global World Overview of Conservation Approaches and Technologies (WOCAT) initiative has developed standardised tools and methods to compile and evaluate knowledge available about SLM. This knowledge is now combined and enriched with audiovisual information in order to give a voice to land users, reach a broad range of stakeholders, and assist in scaling up SLM to reverse trends of degradation, desertification, and drought. Five video products, adapted to the needs of different target groups, are created and embedded in already existing platforms for knowledge sharing of SLM such as the WOCAT database and Google Earth application. A pilot project was carried out in Kenya and Tajikistan to verify ideas and tools while at the same time assessing the usefulness of the suggested products on the ground. Video has the potential to bridge the gap between different actor groups and enable communication and sharing on different levels and scales: locally, regionally, and globally. Furthermore, it is an innovative tool to link local and scientific knowledge, raise awareness, and support advocacy for SLM. Keywords: Sustainable Land Management (SLM), knowledge sharing, audiovisual messages, video, World Overview of Conservation Approaches and Technologies (WOCAT)

Desertification research conventionally focuses on the problem – that is, degradation – while neglecting the appraisal of successful conservation practices. Based on the premise that Sustainable Land Management (SLM) experiences are not sufficiently or comprehensively documented, evaluated, and shared, the World Overview of Conservation Approaches and Technologies (WOCAT) initiative (www.wocat.net), in collaboration with FAO’s Land Degradation Assessment in Drylands (LADA) project (www.fao.org/nr/lada/) and the EU’s DESIRE project (http://www.desire-project.eu/), has developed standardised tools and methods for compiling and evaluating the biophysical and socio-economic knowledge available about SLM. The tools allow SLM specialists to share their knowledge and assess the impact of SLM at the local, national, and global levels. As a whole, the WOCAT–LADA–DESIRE methodology comprises tools for documenting, self-evaluating, and assessing the impact of SLM practices, as well as for knowledge sharing and decision support in the field, at the planning level, and in scaling up identified good practices. SLM depends on flexibility and responsiveness to changing complex ecological and socioeconomic causes of land degradation. The WOCAT tools are designed to reflect and capture this capacity of SLM. In order to take account of new challenges and meet emerging needs of WOCAT users, the tools are constantly further developed and adapted. Recent enhancements include tools for improved data analysis (impact and cost/benefit), cross-scale mapping, climate change adaptation and disaster risk management, and easier reporting on SLM best practices to UNCCD and other national and international partners. Moreover, WOCAT has begun to give land users a voice by backing conventional documentation with video clips straight from the field. To promote the scaling up of SLM, WOCAT works with key institutions and partners at the local and national level, for example advisory services and implementation projects. Keywords: Sustainable Land Management (SLM), knowledge management, decision-making, WOCAT–LADA–DESIRE methodology.

Global investment in Sustainable Land Management (SLM) has been substantial, but knowledge gaps remain. Overviews of where land degradation (LD) is taking place and how land users are addressing the problem using SLM are still lacking for most individual countries and regions. Relevant maps focus more on LD than SLM, and they have been compiled using different methods. This makes it impossible to compare the benefits of SLM interventions and prevents informed decision-making on how best to invest in land. To fill this knowledge gap, a standardised mapping method has been collaboratively developed by the World Overview of Conservation Approaches and Technologies (WOCAT), FAO’s Land Degradation Assessment in Drylands (LADA) project, and the EU’s Mitigating Desertification and Remediating Degraded Land (DESIRE) project. The method generates information on the distribution and characteristics of LD and SLM activities and can be applied at the village, national, or regional level. It is based on participatory expert assessment, documents, and surveys. These data sources are spatially displayed across a land-use systems base map. By enabling mapping of the DPSIR framework (Driving Forces-Pressures-State-Impacts-Responses) for degradation and conservation, the method provides key information for decision-making. It may also be used to monitor LD and conservation following project implementation. This contribution explains the mapping method, highlighting findings made at different levels (national and local) in South Africa and the Mediterranean region.

Tajikistan is particularly exposed to the risks of climate change. Its widely degraded landscapes are badly prepared to cope with changes in precipitation patterns, increased temperatures, droughts, and the spread of pests and disease. Sustainable land management (SLM) provides a “basket of opportunities” to address these challenges, particularly for increasing land productivity, improving livelihoods, and protecting ecosystems. Within the Pilot Program for Climate Resilience (PPCR) in Tajikistan 70 SLM technologies and approaches on how to implement SLM were documented with the World Overview of Conservation Approaches and Technologies (WOCAT ) tools in 2011. For this purpose a climate change adaptation module was developed and tested in order to enhance the understanding about climate change resilience of SLM practices and community workshops conducted to on adaptation mechanisms by rural communities in Tajikistan. The analysis came up with four guiding principles for applying SLM for adapting to climate change: 1. Diversification of land use technologies and farm incomes; 2. Intensification of use of natural resources; 3. Expansion of highly productive land use technologies; 4. Protection of land and livelihoods from extreme weather events. Furthermore, SLM must be up-scaled from isolated plots to entire zones or landscapes and the project developed the concept of three concentric villages zones, the in-, near- and off-village zones. Land users, advisors, and decision- and policy makers face the task of finding management practices that best suit site-specific conditions. This task is most efficiently addressed in collaborative effort, and building up and managing a respective knowledge platform.
