Zentrale Versorgungsbereiche und Sonderstandorte Stadt Bremen

Abgrenzung der zentralen Versorgungsbereiche und der Sonderstandorte gemäß Beschluss des kommunalen Zentren- und Nahversorgungskonzepts (ZNK), beschlossen durch die Bremische Bürgerschaft am 23.02.2021. Die Stabilisierung und Weiterentwicklung der Stadtteilzentren und der Innenstadt sowie die Sicherung der Nahversorgung in den Quartieren sind weiterhin erklärtes Ziel der Stadtentwicklung. Damit dieses Ziel als Rahmen für die bauleitplanerische Praxis Wirkung entfalten kann, bedarf es einer verbindlich beschlossenen kommunalen Konzeption für die Zentrenentwicklung und Sicherung der Nahversorgung. Das Baugesetzbuch sieht hierfür das Instrument des städtebaulichen Entwicklungskonzepts (§ 1 Abs. 6 Nr. 11 BauGB) vor. Vor dem Hintergrund des übergeordneten Ziels einer nachhaltigen „Stadt der kurzen Wege“, wird am räumlichen Leitbild einer polyzentralen Struktur Bremens festgehalten. Für die Stadt Bremen mit der Innenstadt, 15 Stadtteilzentren (darunter die zwei besonderen Stadtteilzentren Vegesack und Viertel) und 18 Nahversorgungszentren werden insgesamt 34 zentrale Versorgungsbereiche ausgewiesen. Die 2009 festgelegte Zentrenstruktur wurde somit in großen Teilen fortgeschrieben. Die zentralen Versorgungsbereiche sind räumlich konkret definiert und im Sinne des Baugesetzbuches schützenswert. Sie bilden den Schwerpunkt der weiteren Einzelhandelsentwicklung in der Stadt Bremen. Ergänzt werden diese Positivstandorte der Einzelhandelsentwicklung durch sechs Sonderstandorte für den großflächigen nicht zentrenrelevanten Einzelhandel.

The effect of water storage variations on in-situ gravity measurements and their use for hydrology (HYGRA)

Das Projekt "The effect of water storage variations on in-situ gravity measurements and their use for hydrology (HYGRA)" wird vom Umweltbundesamt gefördert und von Helmholtz-Zentrum Potsdam Deutsches GeoForschungsZentrum durchgeführt. Water storage variations in the soil, groundwater, snow cover and in surface water bodies cause a gravitational effect due to mass attraction. Thus, there exists a strong interrelation between hydrology and gravity. From a hydrological perspective, the estimation of water storage and its spatio-temporal changes is essential for setting up water balances and for effective water use and management. However, direct measurements of local water storage changes are still a challenging task while time-variable gravity observations are a promising tool as an integrative measure of total water storage changes. From a geodetic perspective, the hydrological gravity effect is an interfering signal, which imposes noise on gravimetric measurements and thus has to be eliminated from the gravity records. Superconducting gravimeters (SG) enable the in situ observation of the temporal changes of the earth gravity field. These SG data contain information about polar motion, earth tides, oscillations of the earth, atmospheric pressure and hydrology. But still variations in local water masses have a significant influence on SG measurements. Hence, the question is: How does local water storage change influence the signal of SG measurements? Objective: The objective of the HYGRA project is to separate the local hydrological signal from the integral signal of the SG records. From the geodetic perspective, this will provide a tool to remove the unwanted hydrological noise in SG recordings. At the same time, the hydrological gravity signal bears the potential to estimate hydrological state variables (ground water, soil moisture). Study Area: The HYGRA project focuses the relation of local hydrology and gravity in following study areas: Geodätisches Observatorium Wettzell, Deutschland; South African Geodynamic Observatory (SAGOS). Method The investigation of the interrelation between hydrology and geodesy is done by following worksteps: 1. 4D Simulation of the influence of water storage changes on the superconducting gravimeter; 2. Measuring and modelling of the different water storages; namely groundwater, soil moisture and snow; 3. Transformation of the water storage changes to a gravimetric signal; 4. Comparison between the measured gravity change by the SG and the estimated hydrological gravity response.

BioAndes - Biodiversity in the Andes

Das Projekt "BioAndes - Biodiversity in the Andes" wird vom Umweltbundesamt gefördert und von DEZA, Direktion für Entwicklung und Zusammenarbeit durchgeführt. The three priority countries of SDC in the Andean region of Latin America; Bolivia, Ecuador, and Peru, are among the so-called megadiverse countries in terms of biological diversity, as defined at the Johannesburg Earth Summit in 2002. All three countries have identified their richness in cultural and biological diversity as one of the key potentials for the diversification of their economies and for pro-poor growth. Recognizing that the extraordinary biodiversity and the resulting economic benefits and environmental services must be preserved on a long-term basis the three countries have declared between 12 and 18% of their surface as protected areas. However, this alone will not allow to maintain existing degrees of biodiversity: A substantial part of the overall biological diversity is located outside protected areas, in particular in the cultural landscapes of agro, silvo and pastoral ecosystems. A high number of rural, resource-poor people are associated with these systems and directly benefit from the improvement of management of them. Because of the potentially important added value that can be expected through a systematic enhancement of regional exchange and joint activities, BioAndes is designed as a regional program for Bolivia, Ecuador and Peru promoting the sustainable management of biodiversity in non-protected areas. The characteristics of the program have been defined according to the winning proposal of a regional bid. The winning consortium is led by the public University of Cochabamba-based AGRUCO (Bolivia) and is further composed of Ecociencia (Ecuador) and ETC (Peru). AGRUCO and Ecociencia are longstanding partners of SDC. The Center of Development and Environment (CDE) of the University of Berne will provide a backstopping to the consortium and ensure the integration of BioAndes in the international exchange of knowledge. The vision of the program is that stakeholders of biodiversity in the three countries have significant impacts on the respect and valorization of the bio-cultural heritage of the Andes through an increased human and institutional capacity for the sustainable management of biodiversity in non-protected areas. The mission is to enhance inter-institutional collaboration through the creation of functional platforms at sub-national, national and regional levels that promote joint learning processes, communication, empowerment, economic development and policy incidence, based on the recognition of the multidimensional nature of biodiversity. Special attention is paid to the sustainable management of bio-cultural production systems in non-protected areas. By focusing on the sustainable management of bio-cultural systems, the program is complementary to the SECO-programs, which emphasize trade-related issues. (Text gekürzt)

BioVeL - Biodiversity Virtual e-Laboratory

Das Projekt "BioVeL - Biodiversity Virtual e-Laboratory" wird vom Umweltbundesamt gefördert und von University Cardiff, School of Computer Science and Informatics durchgeführt. Biodiversity Virtual e-Laboratory (BioVeL) meets the needs of Europes Biodiversity Science research community with tools for pipelining data and analysis into efficient workflows, urgently needed to understand biodiversity in a rapidly changing environment. BioVeL customises, deploys and supports the Taverna / myExperiment / BioCatalogue family of software to achieve this. Close user involvement is crucial to successful design and implementation of virtual laboratories. Close support and guidance makes all the difference in uptake of tools and their continued success. BioVeL places particular emphasis on targeted networking activities with specific sub-communities and tailored service activities that deliver training, helpdesk and consultancy assistance to solve specific problems. Using agile processes, BioVeL defines and deploys (web) service sets and workflow packs catering for sub-communities within the domain. The project focuses on pilot topic areas: i) DNA sequence-based phylogeny and metagenomics services that help link knowledge of model organisms to a broad range of species, that provide a measure of genetic diversity used in conservation planning and that help to understand adaptation in relation to climate change; ii) Taxonomy services to provide the underpinning checklist of diversity in Europe, identification aids to native, invasive and economic species; iii) Niche and population modelling for species, to better understand the processes of conservation and invasive species management; and, iv) Ecosystem functionality and valuation services, to improve modelling capabilities to ecosystem services and CO2 sequestration. Through use of gateways, workflows composed in the BioVeL environment can be executed on a wide range of computing resources, including European e-Infrastructures (EGI, PRACE, etc.). Joint research activities will investigate improvements to ease of use of workflows by exploring new middleware approaches to easier user interfaces.
