The development of empirical data and action goals for “Green in the City” represents a basis for the pursuit of a more sustainable urban development, as green and blue infrastructure significantly contributes to the quality of life in cities. In this context, indicators for assessing the ecosystem service “recreation in the city” were proposed and calculated, mapped and interpreted for all major German large towns and cities. The main indicator “accessibility of urban green spaces” developed in the study is a quite simple, robust and reproducible measure. It combines current geodata of green spaces with their accessibility. The indicator allows a comparison of different cities. If the calculation is repeated it allows a monitoring and the identification of trends. Taken as a whole, 74.3 % of the inhabitants of the 182 towns and cities studied (all towns and cities ≥ 50,000 inhabitants) can reach both smaller urban green spaces and water areas (≥1 ha) within a linear distance of 300 m (≈ 500 m walk), and within a linear distance of 700 m (≈ 1,000 m walk) large green spaces and water areas (≥ 10 ha) are accessible. © 2016, Verlag Eugen Ulmer.

The article gives a short overview of GIS-based procedures and gives insight into the research unit: "Monitoring of settlement and open space development" of the Leibniz Institute of Ecological Urban and Regional Development (IOER). On the basis of geo data several indicators from the fields of settlement, open space, nature reserves, population, traffic occurancy and landscape fragmentation are presented. For calculating building-based settlement indicators, the analysis of the Official Building Polygons of Germany is further discussed. All indicators are depicted in thematic maps, thus allowing for spatial and chronological comparisons. In addition to administrative spatial units (federal state, region, district, municipality), the indicator values are also presented in scales of various cell widths. Furthermore the patented program SEMENTA® is briefly discussed which is based on an automated evaluation of analogue maps. The high-resolution, Germany-wide monitoring requires an enormous volume of data and it is therefore a great challenge to ensure the automatic processing of this geodata.

Using the example of the catchment area of the Jahna river in Saxony, Germany, a status and deficit analysis was conducted, taking the environmental objectives of the EU Water Framework Directive as benchmark. No body of water in the investigation area is currently in a good ecological condition. Based on the findings in the agricultural sector, the nutrients nitrogen and phosphorus as well as the acceptance and costs of measures were determined as target variables. Cases of significant water pollution were identified and spatially differentiated risk and reduction potentials were specified. Multi-criteria analysis in the form of utility value analysis was applied to support an objective decision-making process in the selection and prioritization of measures to reduce erosion and nutrient inputs to water. If all target variables are weighted equally, conservation tillage practices in the critical source areas and cultivation of catch crops are the measures with the highest benefit in the Jahna river basin. A benefit-cost ratio of 2 to 1 was estimated.

In the context of the European Biodiversity Strategy 2020 Germany has been requested to map and assess the ecosystems and their services at national level together with all EU Member States. First national indicators and cartographic representations have been proposed. The first results show a significant need for further methodological development to generate really new information that may be of relevance and benefit to EU reports and strategic decisions in Germany. The article discusses the respective backgrounds and activities. © 2015, Verlag Eugen Ulmer. All rights reserved.

Concept of national indicators for ecosystem services in Germany – Further development, types of classes and sheet of indicators Target 2, Action 5 of the EU Biodiversity Strategy stipulates that the member states will map and assess the state of the ecosystems and their services (ES) and promote the integration into the reporting systems at the EU and national level by 2020. Indicators for capturing and assessing ES are therefore needed. The contribution indicates, based on the underlying framework concept, for which ES class types national ES indicators for Germany are to be developed in the context of an ongoing research project and how they are to be described in an indicator specification. By way of the example of the provisioning service “raw wood production” and the development of the main indicator “annual accrual of wood” and six additional indicators, the study illustrates the concrete procedure, including discussion of data, results and target values as well as monitoring aspects and delimitation from other indicator systems. © 2016, Verlag Eugen Ulmer.

Environmental change and management activities were observed by means of a combined plot sub-catchment approach in forested areas with high share of degraded peat bogs in the upper Ore Mountains using the example of Carlsfeld watershed. The investigation focused on pathways and control factors of water and matter balance. Especially we discuss the parameter 'Dissolved Organic Carbon (DOC)' and 'Spectral Absorption Coefficient at 254 nm (SAK 254)' in its time dynamic and spatial characteristic. The results represent basics for stakeholder interests of user and nature protection.

Owing to its ecological approach, the objectives of the European Water Framework Directive (WFD) have much in common with the objectives of nature conservation. This is also reflected in the first generation of programmes of measures and river basin management plans which were adopted in 2009. The greatest potential for optimising the mutual synergies between water management planning and nature conservation resides in more concrete designation of planning contents, in the integration of information regarding protected sites, species and ecological networks in the planning process and in enhancing the function of groundwater-dependent terrestrial ecosystems as indicators of water status. Furthermore, good communication and participation of conservation stakeholders in the planning process, as well as improving the assessment of impacts on fauna, flora and biodiversity in the Strategic Environmental Assessment of the programmes of measures, may contribute to strengthening nature conservation in river basin management planning. The current updating of the programmes and plans should be used to implement the recommendations given. © 2015 W. Kohlhammer, Stuttgart.

In order to meet the growing challenges relating to the protection of nature and conservation of biological diversity, professionally founded strategies are of great importance. Saxony has already had an appropriate landscape management strategy since 1999, which was designed for a 10 year-period and had to be renewed. For that purpose the landscape management accounting system was further developed. This paper explains the methodological framework of habitat management cost accounting - the core of any landscape management strategy - for the example of the Free State of Saxony (determination of maintenance-dependent habitats; necessary measures; estimation of the related costs per year). Implementation aspects are also discussed. The results provide authorities a planning basis for the strategic direction and implementation of important tasks of nature protection and landscape management policy. © 2014 W.

The paper summarises the status of TEEB-related processes, and the national assessment of ecosystems and their services in Russia, as a preliminary result of the Russian-German project 'TEEBi-Russ: Valuation of Ecosystem Services (ES) in Russia, First Steps'. The planned structure of a prototype of a National Report on ES in Russia is presented. Russia harbours a great diversity of natural conditions and ecosystems which are suppliers of ES, and likewise a variety of the socio-economic conditions that shape the demand for these services and their consumption. As a first step, the framework for capturing and assessing ES was defined (classification, indicators, scale, data situation), and a methodology for assessing the services for the federal subjects of Russia was chosen. Finally, the focus of the planned further work is outlined. © 2016 W. Kohlhammer, Stuttgart.
