Abstract
(Englisch)
This thesis presents a study of the environmental impacts of eight different tomato production systems in Austria, Spain and Italy based on a life cycle analysis (LCA) approach. The purpose was to identify the environmental impacts of tomatoes produced in different locations - Vienna and Burgenland in Austria, Almería in Spain and Puglia in Italy, which are sold in supermarkets in Vienna. Own research and data available in the computer model GEMIS were used to evaluate the CO2-emissions during cultivation and distribution of tomatoes. The ecological footprint for the functional unit (1 kg tomatoes at the point of sale) was also calculated.
I analyzed tomato production under the following production systems: (1) soil-less cultures with active heating systems in modern greenhouses (Venlo-houses) in Vienna, (2) soil-less cultures with active heating systems in commonly used glasshouses in Vienna, (3) unheated conventional production systems in plastic greenhouses in Burgenland, (4) unheated organic tomatoes in plastic greenhouses in Burgenland; (5) conventional tomatoes from greenhouses in Almería and (6) canned tomatoes grown in open fields in Puglia. Two hypothetical systems to suggest possible future trends were outlined: (7) a heated plastic greenhouse in Burgenland and (8) a heated greenhouse in Almería.
Heated greenhouse systems in Austria have a higher environmental impact than packaged open field tomatoes from Puglia as well as greenhouse-grown tomatoes from Almería even though the latter were transported by road over a distance of 2700 km. Organic and conventional tomatoes from plastic greenhouses in Burgenland without active heating systems have the lowest emissions.
The results show that transport has less environmental impact than heating. Heating may account for up to 80% of the total CO2-emissions per kg of tomatoes. Further, short distance transport is found to have a higher environmental impact than long distance transportation.
The CO2-emissions per kg of tomato from the eight different production systems are: (1) 1,1 kg CO2 per kg of tomatoes from Austrian Venlo-houses (2) 1,4 kg CO2 per kg of tomatoes from commonly used Austrian glasshouses (3) 0,1 kg CO2 per kg of tomatoes in conventionally grown plastic tunnels in Burgenland (4) 0,1 kg CO2 per kg of organic tomatoes from plastic tunnels in Burgenland (5) 0,4 kg CO2 per kg of tomatoes from Almería and (6) 0,7 kg CO2 per kg of canned field tomatoes from Puglia. The CO2-emissions from the hypothetical systems are: (7) 0,6 kg CO2 per kg of tomatoes from heated organic cultures in Burgenland and (8) 1,5 kg CO2 per kg of tomatoes heated with propane gas in Almería.
