Andalucía's drought crisis can be seen all the way from outer space, according to a worrying satellite image released by Nasa.
The US agency revealed how the region's drought appears to cameras beyond the stratosphere, where the olive-producing territory is stained brown.
The image taken from the Terra satellite was compared to images taken in May last year, which depicted Andalucía as much more green and lush. A year later, the brown tones indicate a serious lack of rainfall.
In another image, the US space agency shows large irregularities in the Normalised Difference Vegetation Index (NDIV), which indicates the health of vegetation.

Healthy vegetation reflects a more infrared light and less visible light than dead vegetation. The ravages of drought can also be seen here, with half the country coloured brown.
Since the start of the water year on 1 October 2022, Spain has received 28% less rain than expected in mid-May 2023, a situation that is taking a heavy toll on reservoirs and crops.
