Das DBU-Projekt IUMBO : neue Landschaftsstrukturen für Bördestandorte zur Entwicklung von Biodiversität und zur Sicherung landschaftlicher Funktionen

Bördestandorte werden wegen ihrer Fruchtbarkeit seit Menschengedenken ackerbaulich genutzt. Sie stellen heute in der Regel „ausgeräumte“ Landschaften dar, d. h. es existieren dort nur noch wenige strukturbildende Elemente. Das war nicht immer so. Erst seit Beginn der Industrialisierung und Technisierung auch im ländlichen Raum wurde aus der zur biologischen Vielfalt beitragenden Landwirtschaft ein Wirtschaftszweig, der die natürlichen Ressourcen beeinträchtigt. Das Mitteldeutsche Trockengebiet, im Regenschatten des Harzes liegend, zählt mit seinen Bördegebieten zum Typus des ländlichen Raumes mit günstigen Produktionsbedingungen in der Landwirtschaft. Die naturräumliche Entwicklung dieser Gebiete widerspricht jedoch den Zielen des Natur- und Umweltschutzes. Hier muss eine Umkehr negativer Trends bei der Bewahrung der biologischen Vielfalt bzw. dem Schutz der Ressourcen Boden, Wasser und Luft angestrebt werden

Changes of landscape structure and soil production function since the 18th century in north-west saxony

The objectives of this paper are (1) to reconstruct time series of the historical and current landscape structures based on historical documents and serial cadastral maps, (2) to analyse the changes of agricultural production function by the application of historical soil assessments and (3) to analyse the connections between landscape structure and production function in reference to the social and economic driving forces. The case study area is today an intensively-used agricultural landscape located nearby Taucha-Eilenburg (NW-Saxony), Germany. Arable landscapes in Germany are changing with increasing dynamics: valuable structures and landscape functions of the traditional and multifunctional landscape were lost. New landscape structures replaced the traditional ones slowly or sometimes also in short time steps. Therefore, this paper focuses on the changes of landscape structures and that of the soil production function induced by land use since the 18th century. The changes are analysed on the basis of historical and serial cadastral maps and documents by covering four time steps from 1750 to 2005. The historical maps were scanned, geo-referenced and digitalised in GIS. Thus, quantitative analysis of landscape structure changes on parcel level is enabled. The production function is explicitly reconstructed on the basis of the Prussian Taxation of the real estate of 1864 (Preußische Grundsteuerbonitierung) and The German Soil Taxation (Reichsbodenschätzung) of 1937. Changes observed on the serial cadastral maps were linked with the social and economical driving forces and the soil production  function. Moreover, there is a high demand for the development of methodologies to analyse and to assess time series of landscape structures, land use and landscape functions in the historical context of landscape development

Model for the optimal localisation of linear landscape elements based on functional assessment

In the last decades a multitude of assessment methods for landscape functions have been developed (Marks et al. 1989, Bastian and Schreiber 1994). The methods include detailed knowledge from the fields of different sciences and result in maps of landscape risk surfaces. GIS-based models are used to analyse and to asses the landscape functions. New ways are explored by the combination of mathematical methods and spatial data. The assessment of landscape functions is a suitable approach in land uses decision making, especially if a number of different and opposing function assessments are available for the same region. For opposing aims, a method for the integration of land uses in decision making is essential. The authors have developed the framework on multi-criteria landscape assessment and optimisation (MULBO) (Meyer and Grabaum 2003, Meyer 2006, Meyer and Grabaum 2008). MULBO offers a powerful alternative to the common structured aggregation procedures used in landscape planning. The assessment methods integrated as tools in MULBO are validated (Gruehn 2005). The MULBO-framework focuses on the objectification of the planning process by the integration of multiple assessment results into optimal compromises considering different functions of a landscape and into future land use pattern mosaics or distributions. So far the scenario approach of MULBO for local greenway planning has calculated new spatial distributed land uses. The integration of linear landscape elements into MULBO is now realised. Linear landscape elements are of high impact on cultural landscapes e.g. for water river catchment problems, wind erosion, biodiversity and recreation purposes

The Land Use - Land Degradation Nexus in Mediterranean Landscapes: – Drivers of Changes And Key Processes at Selected Natura 2000 Sites of Crete, Greece

The land use–land degradation nexus in Cretan landscapes in regions with Natura 2000 sites was analyzed by an explorative expert driven study based on literature, field work and photo documentation methods with the aim of determining status, drivers and key processes of change. Drivers of current land use changes have been worked out by (1) general tourism developments and tourism related land uses; (2) irrigated olive yard developments; (3) fenced large-scale goat pastures and (4) large scale greenhouses. Key processes of change have been identified and qualitatively assessed for 5 regions with NATURA 2000 areas based on a non-ranked set of 11 descriptive indicators. The analysis includes the status-description and the importance assessment of land degradation processes in selected NATURA 2000 sites. Threats and pressures taken from the NATURA 2000 documentation and the land use – land degradation nexus and the analysis are a suitable basis for future land management in order to reach land degradation neutrality. The result of our analysis opens a new research field for a better integration of the normally thematically isolated analysis in geography, biology/nature conservation and agricultural policy analysis about the drivers and processes in landscape systems towards a better understanding the trends in land cover change (e.g. vegetation/soil degradation), the trends in productivity or functioning changes caused by land uses and as well for the trends in carbon stock change

Knowledge Mapping Analysis of Rural Landscape Using CiteSpace

This study visualizes and quantifies extant publications of rural landscape research (RLR) inWeb of Science using CiteSpace for a wide range of research topics, from a multi-angle analysis of the overall research profile, while providing a method and approach for quantitative analysis of massive literature data. First, it presents the number of papers published, subject distribution, author network, the fundamental condition of countries, and research organizations involved in RLR through network analysis. Second, it identifies the high-frequency and high betweenness-centrality values of the basic research content of RLR through keyword co-occurrence analysis and keyword time zones. Finally, it identifies research fronts and trending topics of RLR in the decade from 2009 to 2018 by using co-citation clustering, and noun-term burst detection. The results show that basic research content involves protection, management, biodiversity, and land use. Five clearer research frontier pathways and top 20 research trending topics are extracted to show diversified research branch development. All this provides the reader with a general preliminary grasp of RLR, showing that cooperation and analysis involving multiple disciplines, specialties, and angles will become a dominant trend in the field

Risk Management as a Basis for Integrated Water Cycle Management in Kazakhstan

Integrated Water Cycle Management (IWCM) aims to bring together a diversity of social, environmental, technological and economic aspects to implement sustainable water and land management systems. This paper investigates the challenges and opportunities facing Kazakhstan as it its efforts to move towards a more sustainable approach to managing its finite and highly stressed water resources. The use of a strategic-level risk governance framework to support a multi-disciplinary Kazakh-EU consortium in working collaboratively towards enhancing capacity and capability to address identified challenges is described. With a clear focus on addressing capacity building needs, a strong emphasis is placed on developing taught integrated water cycle management programmes through communication, stakeholder engagement and policy development including appropriate tools for managing the water issues including hydraulic models, GIS-based systems and scenario developments. Conclusions on the benefits of implementing an EU-style Water Framework Directive for Central Asia based on a risk management approach in Kazakhstan are formulated

Integrated Approach to Estimate Land Use Intensity for Hungary

An integrated approach was applied in this article to provide a medium-scale map of land use intensity for Hungary. The main goal was to estimate its value by a small set of parameters, which are freely available and have a high resolution. The basis of the evaluation was the CORINE 2012 dataset, and a matrix method was applied to integrate the ratio of natural/semi-natural vegetation, woody vegetation and the Natural Capacity Index in the assessment to describe the complex approach of land use intensity. The medium level land use intensity map provides information for decision makers/landscape planners on the current status and spatial pattern of anthropogenic impact and indicates those hot-spots where land use intensity is high and should be focused research and management to intervene in order to encourage sustainable land use. 46% of the arable lands in Hungary show the most intensive land use. Comparing the map with the previously published hemeroby map of Hungary, more intensive impact on landscape transformation through human action was found. In agricultural areas both researches agree that the intensity and human activity is really high, and the lowest intensity class is rare in Hungary except for mountain regions and protected areas
