Revitalizacija kraške kulturne krajine z ukrepi sanacije pogorišč po požaru na Krasu leta 2022

Bizalj, Laura (author), Gazvoda, Davorin (mentor)

Kras je zaradi svojih naravnih danosti – sušnega podnebja, pomanjkanja površinske vode in burje, požarno zelo ogrožen. Hiter proces zaraščanja tega območja je povzročil spremembo značilne kraške kulturne krajine, hkrati pa povečal dovzetnost prostora za požare, kot je bil požar na Krasu poleti 2022. Magistrsko delo požarišče na Krasu obravnava kot priložnost za vzpostavitev požarno odporne krajine z okrepljeno identiteto, preko obnove značilnih kraških prvin in mozaičnega umeščanja značilnih kmetijskih rab. Analitični del vključuje prostorsko in požarno analizo ter pregled sanacijskih dokumentov. Osredotoča se na območje okoli Kostanjevice na Krasu. Na podlagi analiz sta oblikovana dva predloga za razmestitev rabe v prostoru, ki upoštevata naravne pogoje in zgodovinske vzorce, ter predlog pasov protipožarnih presek. Prvi predlog obravnava širše območje požarišča – okolico Kostanjevice na Krasu, kjer je predstavljena razmestitev treh širših kategorij rab, s podanimi smernicami za vsako območje. Rezultat te karte je nastal z modeliranjem podatkov v programu ArcGis. Drugi predlog pa obravnava ožje območje – Korita na Krasu, in prikazuje razmestitev specifičnih rab na bolj oblikoven način, z upoštevanjem prej določenih smernic. Ta predlog je bil narejen z ročnim umeščanjem poligonov za posamezno rabo, zato rabe mozaično prepletajo in ustvarjajo bolj odprto kraško krajino, kjer je zveznost goriva manjša, kar posledično zmanjša tudi požarno ogroženost, hkrati pa povečuje biotsko raznovrstnost, krepi prostorsko identiteto Krasa.

• Title: Revitalization of the Karst cultural landscape through fire damage restoration measures, Karst wildfire 2022

Abstract

The Karst region is highly susceptible to wildfires due to its natural characteristics—arid climate, lack of surface water, and strong winds. Rapid overgrowth has transformed the traditional cultural Karst landscape and increased its vulnerability to fires, such as the major wildfire that occurred in the summer of 2022. This master’s thesis treats the burnt area as an opportunity to establish a fire-resilient landscape with a strengthened identity, through the restoration of typical Karst elements and the mosaic placement of characteristic agricultural uses. The analytical part includes spatial and fire analyses as well as a review of post-fire rehabilitation documents. The focus is on the area around Kostanjevica na Krasu. Based on the analyses, two spatial land use proposals were developed, both respecting natural conditions and historical land use patterns, along with a proposal for fuelbreaks. The first proposal addresses the broader fire-affected area—the surroundings of Kostanjevica na Krasu—and presents the distribution of three general land use categories, each accompanied by specific guidelines. This map was created by modeling data in ArcGIS. The second proposal focuses on a more detailed area—Korita na Krasu—and shows a more illustrative arrangement of specific land uses, following the previously defined guidelines. This proposal was created through manual placement of polygons for each use, resulting in a mosaic landscape pattern that opens up the Karst terrain, reduces fuel continuity, lowers wildfire risk, enhances biodiversity, and reinforces the spatial identity of the Karst region.
