Cloud seeding to be used as irrigation method for Dubai Expo 2020 site
Cloud seeding operations in the UAE are set to increase in the run-up to Expo 2020, with event officials confirming collection and usage of rainwater as one of the ways to irrigate the 438-hectare site, Arabian Business reports.
In the past few months, the UAE’s National Centre of Meteorology and Seismology (NCMS) launched number of cloud seeding operations, which led to an increase in the amount of rainfall across the country.
Cloud seeding is a way to change the amount and type of rain that falls from clouds by dissolving substances into the air that serve as cloud condensation.
WAM reported this week that the UAE dams have collected around 30 million cubic metres in 2016 as a result of a unique climate phenomenon witnessed by the country, characterised by high levels of rainfall that have not been experienced in the last three decades.
Ahmed Al Khatib, vice president of property, Expo 2020 Dubai said rainwater will used for irrigation at the site along with recycled grey water and underground water.
“We are hoping [to increase cloud seeding operations] and we are working with authorities on the matter,” he said.
The official said they were in talks with Dubai Municipality and Dubai Health Authority to find ways to process water harvested from humidity and to make it potable.
“We are harvesting water from humidity that we will use for irrigation. But now we are in discussions with authorities to have that water treated to a level that it can be drinkable,” he added.
