GI2013 ppt furdik_analysis of the natural conditions for sustainable development

  1. 1. ANALYSIS OF THE NATURALCONDITIONS FOR SUSTAINABLEDEVELOPMENT OF URBAN STRUCTUREIN BRATISLAVA - RAČA, SKJuraj Furdík, Rostislav Ondruš, Dávid Murín, Daniel Furdíkfurdik@fa.stuba.sk, www.fa.stuba.sk
  2. 2. THE PROJECT CHARACTERISTIC• Analysis of the natural conditions forms an basic part of the urban andlandscape study "Vineyard - City District Bratislava - Rača", which on theorder of the Local Authority city district Bratislava - Rača is compiled bya team of authors led by prof. Ing. arch. P. Gal, PhD. and Ing. arch. J.Furdík, PhD. Faculty of Architecture, STU in Bratislava was coordinatorfor project of this analysis.• The social order was based on the role of mutually contradictorypressures on the territory of Rača vineyards, where on the one side arethe defenders of the interests of the vineyard and on the other, theinterests of owners and developers.
  3. 3. • Delimitation of the area was given by city districts and was designed by current borders ofvineyards in the Master plan of Bratislava despite the fact that, even now, are functional andpromising area of vineyards outside these borders, it means, that he was not interested insolving this problem with a comprehensive review of all the available areas in the cadastralterritory of the city district Bratislava - Rača. Solved territory consists of five compact sectorswith a total area of ​​251.7 hectares.THE AREA

  5. 5. • Analysis of the natural conditions (in her summary of terroir) should provide anobjective basis, which would determine the most suitable localities for themaintenance of vineyards in the solution area. Of course, this analysis of thevineyards in Rača is not sufficient. The next steps must be completion of urbanstudies and planning scheme of a particular legal system and support mechanismsthat make real the existence of a specific viniculture in immediate contact with theurban structure of Bratislava.• Analysis of the natural conditions, with emphasis on the analysis of the spatialcharacteristics of the territory, using a digital terrain model (Eurosense Ltd.)becomes the model initial analysis project vineyards in Slovakia, which expressesthe terroir key features affecting the quality of wine production.• Digital terrain model (DTM) from EUROSENCE SLOVAKIA with geographicalinformation systems GRASS and Quantum GIS (open source softwere) provide thebasic framework for spatial analysis of natural conditions in the Rača area ofvineyards.THE MODEL INITIAL ANALYSIS PROJECTVINEYARDS IN SLOVAKIA

  8. 8. HEIGHT GRADES the altitudeHeight grades legibly reflect the altitude, which affects the climate ofindividual plots, in the valleys it is a longer period of fogs, at higheraltitudes is a difference of 1 ° C per 100 meters of height.
  9. 9. Declination of reliefThe declination of relief in direction of the catchment curve in relation to theorientation to the cardinal points has a basic influence on the amount of energyincident on the individual vineyard plots and economy working of vineyard.
  10. 10. The projection of declination in vineyard plotsThe suitability of declination is from 5 ° to 25 °, optimally from 5 ° to 15 °. Theprojection of declination in vineyard plots, which have been formed historically,determines their suitability and orientation to choose the type of grape.
  11. 11. Orientation to the cardinal pointsOrientation to thecardinal points ofthe relieftogether withdeclinationdetermine theappropriatenessof the choice ofvineyards plot inthe solution area.The shading byhorizon isimportant too,because theproximity of theforest and theSmall CarpathianMountains. Mostfavorableorientation is inthe order of 1.south, southwest,2. southeast,west.
  12. 12. The sunlight rays angle fall and the shading of reliefThe sunlightrays angle falland theshading ofrelief.Comprehensiveview on theappropriatevineyard areasprovidesanalysis of thesunlight raysangle fall andthe shading ofrelief. Giventhe growingseason vine inthe analysissingled outthree keydays (20.3, 21.6, 23.9) and three breakthrough times - times of the day (2 h aftersunrise, noon, 2 h before sunset). The average of the sunlight rays angle falls andsumof shadows created a complex output determining the most appropriate locationsfor growing vines.

  14. 14. Analysis of direct sunlightDirectsunlight in itssummaryreflects thesum ofsuitablepropertiesfrom previousorographicfactorsanalyzed areaRačavineyards.Directsunlight(abstracted -withouttaking intoaccount theimpact ofcloud andotherdynamiccomponents of weather) is expressed in hours of glare and average daily total solarradiation Wh/m2/deň. Given the representativeness of the factor analysis was carriedout of direct sunlight in five key days (20.03, 05.05, 21.06, 07.08, 23.09) which is higheroptimization analysis result.

  16. 16. Forms of georeliefA separate part of the analysis was to analyze the forms of georelief, which is astrong orographic factor, but its expression in our GIS analysis was highlystructured without opportunity of examination for impact of georelief forms toquality of vineyard.
  17. 17. Conclusion• Sample introductory analysis of spatial natural conditions Rača vineyard was limited time andfinancial possibilities of the project, but nevertheless becomes a useful tool to protectvineyards and sustainable development of urban structures in contact with the existingbuildings of the city. Usage of analysis in favor harmony of two conflicting functionsgenerates the perspective of optimalized settlement structure with the agricultural landscapeof vineyards. An obvious prerequisite for the wine business becomes integrated productionwith optimal protection of the natural environment.• The use of GIS technology in the Slovak wine-growing areas opens new possibilities forevaluating the quality wine areas and creates a precise definition of the conditions for qualityclasses of vineyards and their precise spatial destination. Obvious completion methodologyimplied waiting for social order.
