The Massive Greenhouses of Almeria — Spain

Since the 1980s, the small coastal plain, some 30 kilometers southwest of the city of Almeria, has developed the largest concentration of greenhouses in the world, covering 26,000 hectares. Several tons of greenhouse vegetables and fruits such as tomatoes, peppers, cucumbers and zucchinis are produced here annually. More than half of the Europe’s demand for fresh fruits and vegetables are grown under the plastic shades, fuelling the province of Almeria's economy by $1.5 billion in annual revenue.

Spanish city of Almeria has turned into the largest greenhouses are concentrated in the world, who took almost 26,000 hectares. Every year several thousand tons are grown greenhouse vegetables such as tomatoes, peppers, cucumbers and zucchini.

But 35 years ago, this region in the southeast of Spain was dry and arid, and desert-like, receiving an average of 200 mm of rainfall a year. In fact, Spaghetti western films were once shot here, because the land was so dry and barren. But with imported soil and fully hydroponic systems that drip-feed chemical fertilizers into grow-bags, over the last 35 years, the area has been intensively used for agriculture.

35 years ago, this region in the south-east of Spain was known only for its dry and harsh climate. Everyone here was like a desert, and in the year the rainfall was only 200 mm of rain. There’s even filmed many European westerns, because the scenery is well suited.

A mix of thousand of smallholders and large companies tend the crops inside the plastic greenhouses. Temperatures can reach more than 45 degrees Celsius inside. Many Spanish workers find it too hot to work and the conditions too brutal so the sweat-houses are staffed mainly by legal and illegal immigrants from Africa and Eastern Europe. One hundred thousand immigrants are thought to work in the greenhouses and many believe it is the lack of workers-rights that help the businesses to be profitable. Many ‘farms’ have no toilets and women are often forced into prostitution. Some workers are also sold contracts to work, which have to be repaid to their bosses. The Network for The Promotion of Sustainable Consumption in European Regions, estimate that workers are paid between 33 and 36 Euros per day.

However, imported salt and complete hydroponic systems that feed the plants with chemical fertilizers last 35 years, let this place turn into a real paradise of agriculture. Greenhouse, of course.

Almeria's sea of white-roofed greenhouse is so vast that researchers from the University of Almeria have found that by reflecting sunlight back into the atmosphere, the greenhouses are actually cooling the province. While temperatures in the rest of Spain have climbed at rates above the world average, the local temperature has dropped an average of 0.3 degrees Celsius every 10 years since 1983.

It is believed that in these greenhouses running 100,000 immigrants, and many believe that it is the lack of labor rights of local workers makes this place thrive. On many farms there are no toilets, and women often work as prostitutes.

The greenhouses are so successful that they have swamped the plain of Dalías, moving up the valleys of the nearby Alpujarra hills, one of Spain's most pleasant and unspoiled areas. A few small towns in the area have been completely swamped by the white plastic farms. Plastic manufactures and recycling companies have also set-up in the region, where discarded plastic sheeting and rubbish lies wherever blocking up riverbeds. Last month the death of a sperm whale that washed up on Spain’s south coast was linked to the Almeria greenhouses after it was found to have swallowed 37 pounds (17kg) of plastic waste dumped into the sea. Empty pesticide containers bearing toxic warnings lie among the plastic litter. On the coast at El Pozuelo plastic waste is piled calf-high.
