在皮尼奥斯河流域(希腊中部)约4000公顷的土地上种植工业番茄，为农民提供了可观的收入。在这项研究中，连续三年对24个不同农场的工业番茄种植到收获之间的水足迹(WF)进行了估算。选定的农场代表了流域内主要的农业气候带和土壤质地类别。绿色、蓝色和灰色的WF计算基于每个农场试验田的数据集，包括灌溉水量、气象、土壤和作物产量数据。结果表明，番茄水分利用率为37~131m~3/t，平均为61m~3/t。WF的变化主要取决于作物产量、当地农业气候和土壤条件。绿色、蓝色和灰色的WF组分平均分别为13、27和21立方米/吨。这些结果揭示了WF在理解番茄生产如何与淡水的可持续利用和地方一级的污染有关方面的重要性。
Industrial tomatoes are cultivated in about 4000 ha of the Pinios river basin (central Greece), providing significant income to the farmers. In this study, the water footprint (WF) of industrial tomatoes between planting and harvest was estimated in 24 different farms for three consecutive years. The selected farms were representative of the main agro-climatic zones and soil textural classes within the river basin. Green, blue and grey WF calculations were based on datasets of the experimental plots for each farm, including irrigation water volume, meteorological, soil, and crop yield data. The results showed that the WF of tomatoes ranged from 37 to 131 m3 water/ton tomatoes with an average of 61 m3/ton. The WF variation depended mainly on crop yield, local agro-climatic and soil conditions. The green, blue, and grey WF components averaged 13, 27 and 21 m3/ton, respectively. The results reveal the importance of WF in understanding how tomato production relates to the sustainable use of freshwater and pollution at local level.
