investigator in Spain ’s desiccate Southeast are working to restore Islamic - era acequias , canal that constitute an irrigation organisation in Andalucia ’s Sierra Nevada mickle .
Muslims invaded andruledSouthern Spain in the 8th century , bringing in irrigation techniques thatincreased the productionof different craw like citrus fruits and rice . The Sierra Nevada irrigation system , fed by dissolve snow and nearby bodies of water , relies on gravity to transport piss across big husbandry domain without the need for external major power . The channel that make up the system of rules were poke into the ground and often lined with stones .
Some local farmers still utilize parts of the system to irrigate crops , but many of the channels are block after years of disuse . The Guardiandescribedin a account in the first place this month how the system was active into the 20th 100 , but as the local agriculture universe declined , persona were abandoned . However , the ingeniousness and resource of the original builders means the acequias are still brace to sustainably channelize water in the area — they just need a little TLC .

Archaeologist José María Martin Civantos , coordinator ofMEMOLab at the University of Granada , is helping contribute this effort . He sees this projection as a testament to how pre - industrial wiseness can be an authoritative dick in make out water system resource in the future .
“ We want to continue those landscapes and all the environmental values that they have , ” Civantos tell Earther . “ [ This project ] empowers the local community and also recuperate traditional ecological cognition … It ’s about farming policy , environmental policy , and the territorial planning . The melodic theme [ behind ] the activity is not just the restoration . ”
Civantos says endeavour to reinstate the irrigation system by clear out unused channels began in 2014 . volunteer and university scholarly person have worked with local anesthetic to mend the hydrological scheme so that body of water usage for local farming can become more effective in the face of increasing droughts .

A Spanish livestock and farming association lately reported that abouthalf of the country ’s agriculturewill be affected by current droughts , with great impacts to farmers of traditionally rain - fed crop like olives and grape
“ We are in the more desiccated areas of Europe … it ’s something natural in our area . But of course of action , the effects of mood change are more seeable in many ways , ” Civantos said . “ Desertification is increase , but it ’s not only an effect of mood change , it ’s also an effect of land usance changes … the over - victimisation of the aquifers . ”
In the case of the acequias , Spain ’s chronicle has become a tool to avail extenuate how mood change will feign the state . The drouth has also unveil some of the country ’s recent history : After a drier - than - common winter , the Alto Lindoso reservoir ’s water levels dropped to only 15 % capacitance , revealing the deep-set Greenwich Village of Aceredo . The townspeople was on purpose flooded in 1992 after the reservoir was constructed , but with the water now so lowly , people have been able to once again take the air the street of this ghostwriter township .
