AgroaldeaTHE TEMPERATURE FALLS AS THE ROOFS REFLECT PART OF THE SOLAR RADIATION.
A team of researchers from the University of Almería has verified how in this area of the peninsula, There has been a net drop in temperatures in recent years. 25 years compared to the increase suffered in the neighboring provinces.
According to those responsible for the study, the cause of this effect is the more than 26.000 hectares of greenhouses. This effect is called albedo, which is none other than the ability of a certain surface to reflect part of solar radiation.
This has been done since ancient times in which the inhabitants of towns where the sun hits many hours a year, They have painted their houses white to keep them cool. Lanzarote is the clear exponent of the albedo effect.
To reach this conclusion, The authors analyzed the evolution of the temperature collected by six meteorological stations. While in bordering areas the temperature increase is 0.5° per decade, In greenhouses, a decrease of 0.3° per decade has been recorded.
To these measurements have been added the data provided by images taken by NASA's Terra satellite in which the researchers have calculated that each of the 26.000 hectares reflects to the space an average annual power of 580.000 watios.
According to the study, each hectare of greenhouse crop captures 10 tons of CO2, the equivalent of what four cars emit per year.
From this follows the benefit of greenhouses against the greenhouse effect, that conditions climate and changes worldwide.
