Typha). Es soll eine wissenschaftlich basierte Aussage über die natürlichen Bestände der typha Pflanze in Bulgarien getroffen werden, insbesondere, inwiefern die naturräumlichen Voraussetzungen im ausreichenden Maße vorhanden sind. Zudem soll die Eignung der Typhaplatten für Innendämmmaßnahmen im Mehrparteien-Wohnungsbau in Bulgarien untersucht werden. Darstellung der Arbeitsschritte und der angewandten Methoden Im ersten Arbeitspaket (AP1) werden mit Fokus auf die Bausubstanz durch die Kombination von Sekun- därdatenanalyse und Primärerhebungen vorhandene offizielle Referenzinformationen und Strukturen er- fasst (z.B. politische Leitlinien, gesetzliche Rahmenbedingungen, Nutzerverhalten). Im zweiten Arbeitspa- ket (AP2) stehen Untersuchungen zur Herstellung des Materials im Vordergrund. Dies bedeutet, dass eine Analyse hinsichtlich der naturräumlichen Voraussetzungen in Bulgarien vorgenommen wird, um potenzielle und vorhandene Typha-Flächen auf Grundlage einer GIS-Kartierung zu erfassen. Hierfür wird auf Sekun- därdaten von z.B. regionalen/nationalen Verwaltungseinheiten zurückgegriffen. Zudem erfolgt eine Unter- suchung zu den Möglichkeiten dezentraler Produktionsmethoden zur Typhaboardherstellung. Mit dem dritten Arbeitspaket (AP3) werden auf Basis der Erkenntnisse aus AP1 und AP2 im hohen Maße konzeptionelle Arbeiten erforderlich. Ziel der Durchführung dieses Schrittes ist eine Einschätzung auf der Makro- und Mikroebene und die hieraus schlussfolgernde Ableitung notwendiger Anforderungen und Maß- nahmen für die Begünstigung des Wissens- und Technologietransfers im Zusammenhang mit der Anwen- dung des innovativen Baustoffes Typha. Es werden verschiedene mögliche Transferleistungen für relevan- te Stakeholdergruppen aufgezeigt, um hieraus eine Auswahl praktisch geeigneter Maßnahmen zu treffen, diese konzeptionell auszuarbeiten und durchzuführen (z.B. Lehrgänge, Schulungen, Workshops oder Se- minare). Deutsche Bundesstiftung Umwelt An der Bornau 2 49090 Osnabrück Tel 0541/9633-0 Fax 0541/9633-190 http://www.dbu.de Im Rahmen des Vorhabens wurde die Eignung und die Übertragbarkeit des Baustof- fes und des gesamten Lebenszyklusprozesses von TYPHABOARD unter den regio- nalen Bedingungen in Bulgarien angesichts folgender Faktoren untersucht: - Verfügbarkeit des Rohstoffes - Verfügbarkeit geeigneter Arbeitskräfte - strukturellen Eignung des Zielregions - Wirtschaft und Soziales - Realisierbarkeit der Produktionsanlage - Eignung des Bautoffes TYPHABOARD zur Anwendung als Innendämmung bei Mehrfamilienhäusern - Akzeptanz des Baustoffes unter der lokalen Bevölkerung - Akzeptanz des Baustoffes, sowie des gesamten Produktionsprozeses seitens der politischen Entscheidungsträger. Nachdem alle Teilstudien innerhalb des Vorhabens eindeutig positive Ergebnisse bzgl. der Übertragbarkeit des TYPHABOARD-Konzepts geliefert haben, hat das Pro- jektteam an Realisierungszenarios gearbeitet und diese bei den Transferworkshops mit allen relevanten Stakeholdern diskutiert. Das Projekt und seine Inhalte wurden dem fachlichem, aber auch dem breiten Publi- kum in Bulgarien anhand von Publikationen bei nationalen schriftlichen Medien online und in Papierform bekannt gemacht. Im Rahmen der Tagungen der VSU und der Bulgarischen Akademie der Wissenschaf- ten und Künste wurden jeweils die vorgesehenen Projektinhalte, sowie der aktuelle projektstand und die Projektergebnisse dem Fachpublikum und politischen Stakehol- dern in Bulgarien präsentiert. Vorgesehen ist eine umfassende Publikation im Tagungsband „Denkmal & Energie“, sowie bei anderen Fachmedien. Dank der erfolgreichen interdiszipliären und internationalen Zusammenarbeit innerhalb des Vorhabens, konnte das Projektteam eine solide Basis für die Übertragung und die Realisierung des gesamten TYPHABOARD-Konzeptes in seinem gesamten Umfang schaffen. Bulgarien bietet hervorragende Bedingungen und Gegebenheiten dafüdafür. Die politische Entscheidungsträger sehen im TYPHABOARD-Konzept eine Möglichkeit zur sinvollen Nutzung von oft eutrophierten Niedermoorgebieten und zur strukturellen Stärkung be- stimmter Regionen, sowie zur ressourceneffizienten Bestandsoptimierung bei der Mehrzahl der Wohngebäude im Lande. 2.

  • The Central Regions and the Sofia Agglomeration Area
    Maria Shishmanova THE CENTRAL REGIONS AND THE SOFIA AGGLOMERATION AREA Abstract. The research presents central regions in Bulgaria using taxonometric method with relevant conclusions. Each municipality in central regions is particularly examined by the elaborated methodic materials. The developed agglomeration areas are situated in the central regions. Sofia agglomeration area is presented using General Spatial Plan of Sofia municipality and Municipal Development Plan (MDP) of Sofia metropolitan municipality. It is set out the vision of development and its priorities, objectives and measures. Key words: central regions, agglomeration areas, Sofia agglomeration area, General Spatial Plan, Municipal Development Plan. Introduction The Central regions comprise 45 percent of the Bulgarian territory. The agglomeration areas are formed in them. The present study examines the development of the Sofia agglomeration area – a metropolis in the central regions of Bulgaria. The agglomeration areas are formed within the range of the central regions in Bulgaria – 6 agglomeration areas with a center – a large city, 30 agglomeration areas with a center – a medium-sized town. Six of the agglomeration areas are formations with more than three municipalities, five of them are with three municipalities each, ten are with 2 municipalities and the rest 15 are autonomous municipalities with an established core. These areas represent the backbone of the economy and social and human potential of the country. They have the highest degree of competitiveness and attractiveness for investment and innovation. Eighty eight municipalities with a total population of 5885455 people1 are included within the scope of the agglomeration areas, which constitutes 77.4 percent of the population of the country.

  • Annex REPORT for 2019 UNDER the “HEALTH CARE” PRIORITY of the NATIONAL ROMA INTEGRATION STRATEGY of the REPUBLIC of BULGAR
    Annex REPORT FOR 2019 UNDER THE “HEALTH CARE” PRIORITY of the NATIONAL ROMA INTEGRATION STRATEGY OF THE REPUBLIC OF BULGARIA 2012 - 2020 Operational objective: A national monitoring progress report has been prepared for implementation of Measure 1.1.2. “Performing obstetric and gynaecological examinations with mobile offices in settlements with compact Roma population”. During the period 01.07—20.11.2019, a total of 2,261 prophylactic medical examinations were carried out with the four mobile gynaecological offices to uninsured persons of Roma origin and to persons with difficult access to medical facilities, as 951 women were diagnosed with diseases. The implementation of the activity for each Regional Health Inspectorate is in accordance with an order of the Minister of Health to carry out not less than 500 examinations with each mobile gynaecological office. Financial resources of BGN 12,500 were allocated for each mobile unit, totalling BGN 50,000 for the four units. During the reporting period, the mobile gynecological offices were divided into four areas: Varna (the city of Varna, the village of Kamenar, the town of Ignatievo, the village of Staro Oryahovo, the village of Sindel, the village of Dubravino, the town of Provadia, the town of Devnya, the town of Suvorovo, the village of Chernevo, the town of Valchi Dol); Silistra (Tutrakan Municipality– the town of Tutrakan, the village of Tsar Samuel, the village of Nova Cherna, the village of Staro Selo, the village of Belitsa, the village of Preslavtsi, the village of Tarnovtsi,

The four countries around the Black Sea- Bulgaria, Turkey, Georgia and Armenia, are a paradise for mountain biking with innumerable cycle routes on gravel roads, in the mountains and along rough cart roads. Their dramatic natural landscapes offer challenging and rewarding slick rock trails, lush green single track, ruins of ancient civilizations, canyons and secret paths to explore. The mountain biking in and around Black Sea is some of the best trail riding in Europe. There are no restrictions on using bikes on the routes. Most of the routes are suitable for energetic mountain biking. Mountain biking is best between May and June or September and October. Itinerary 2- The “Black Sea Discovery”
