Tridge summary

A new analysis of satellite data has revealed that the global greenhouse area has expanded to over 13,000 km² from just 300 km² 40 years ago. China is the world's leader in greenhouse construction, housing around 60% of them, particularly on the North China Plain. The main crops grown include cucumbers, eggplants, and tomatoes, with an increasing cultivation of berries and fruits. The largest concentration of greenhouses is in Shandong province, northeastern China. The University of Copenhagen, using Landsat images, traced the history of greenhouse construction in the largest clusters and tracked changes in the five countries with the largest greenhouse areas. The growth is considered a global trend, with greenhouses mapped in 119 countries, including major areas in Spain, Italy, Mexico, Turkey, the Republic of Korea, Japan, the Netherlands, and France, as well as 22 African countries for vegetable and flower production.

According to a new analysis of satellite data, greenhouses now cover more than 13,000 km² of land worldwide, up from just 300 km² 40 years ago. This is reported by AgroTimes with reference to the Earth Observatory. It is noted that the greatest growth occurred in China, where 60% of the world's greenhouses are now located. These structures are most concentrated on the North China Plain. The largest concentration of greenhouses in China and the world is more than 820 km² in Shandong province in northeastern China. Cucumbers, eggplants and tomatoes are grown in greenhouses in China. And increasingly valuable berries and fruits such as strawberries, grapes, kiwi and pitahaya are planted in buildings. Total production of tomatoes and cucumbers in China increased 6-fold between 1990 and 2020, although exports remained about the same.
