  • In the sprawling deserts of the United Arab Emirates, there are huge areas of greenery

  • emerging amidst the golden sands.

  • This transformation is not some natural phenomenon, it's by design.

  • It's called desert greening and, for all the UAE's opulence,

  • this may be its most valuable investment yet.

  • The United Nations estimated that by 2025, 1.8 billion people will be living with

  • absolute water scarcity.

  • If you don't have water for people, animals, plant communities,

  • as a nation, you will really struggle.

  • Especially in desert countries increasingly lack of water due to climate change

  • is resulting in less secure water.

  • And the Middle East is home to 12 of the 17 world's mostwater stressed countries.”

  • The UAE receives less than 200 mm of rainfall each year.

  • To put that into context, London soaked up an average of 1,051 mm of rain in 2022,

  • while Singapore drenched in a whopping 3,012 mm during the same year.

  • So, as one can imagine, ensuring enough water for the UAE's population is a real challenge.

  • To continue to support its increasing development and growing population, the UAE government

  • invested more than 20 million dollars in research to start a process called cloud seeding.

  • Cloud seeding enhances the rain in the cloud.

  • The main objective of that to increase the storage of groundwater.

  • It was a direct order from His Highness Sheikh Mansour.

  • When did this start?

  • It was in late 2000 and early 2001.

  • We were partnered with the National Atmospheric Research in the U.S.

  • The entire Gulf region could face a 50 percent reduction in water availability per capita by 2050.

  • The UAE has tried to combat desertification, which is land that is no longer productive

  • because it can't support plant growth.

  • The Emirate spans over 83,000 square kilometres, and around 80% is desert.

  • It's estimated that 75% of our planet's land is already degraded.

  • These lands have become deserts or are uninhabitable.

  • About 12 million hectares of land is lost around the world each year

  • as a direct consequence of drought and desertification.

  • The World Bank estimates the Emirates has lost

  • almost 33,000 hectares of land from 2002 to 2018.

  • The decrease in arable land is primarily due to land degradation.

  • This impacts over 3 billion people.

  • And people that live in desert and dry land ecosystems that cover nearly half of the globe,

  • are particularly vulnerable to the loss of arable land and land degradation.

  • But in the last 50 years, what was once a large desert and a tranquil fishing port

  • has evolved into an urban metropolis.

  • Long before the skyscrapers and bustling cities, the UAE had a history of planting trees

  • in areas that lacked them, a process called afforestation.

  • So what we're seeing across the world, especially some of the countries that

  • have significant desert systems is efforts to green that desert, which means

  • bringing in trees, other plant communities to increase, as the initiatives say,

  • the greenness of the deserts.

  • Take a look at these satellite images of the UAE in the 1980s, and present day.

  • The country's late president sought to provide permanent homes for nomadic Bedouins

  • in the parched desert.

  • His dream set the stage for a nation's ambitious endeavour and their leaders knew that trees

  • could help with the fight against desertification.

  • About two decades ago, theOne Million Treesinitiative was announced by the ruler of Dubai.

  • The plan was to plant 250 thousand trees every year, in collaboration with the Dubai Police Academy.

  • It wasn't long before groves of olive, palms, and the resilient ghafs,

  • the national tree of the UAE, painted the once-empty land with life.

  • When you are planting some of those trees, you can dig different holes to capture water

  • and engineer the landscape so those trees that you're bringing in will be able to survive.

  • And so that's critically important is that it's not only the types of trees that you're bringing in,

  • or in the types of plants you're bringing in for these afforestation projects,

  • but also how you engineer that landscape to be able to receive those plants

  • and that they are able to survive.

  • A tree nursery for theOne Million Treesinitiative was created, spanning more than 130,000 square meters.

  • But challenges loomed large over green dreams.

  • Behold: 'Mall of the World,' a mega shopping center project.

  • It was said that Dubai Holding, the investment vehicle of the Emirates ruler,

  • would require 6.8 billion dollars to build that entertainment district.

  • Could you guess where they wanted to build this mega project?

  • None other than the very land the tree nursery once thrived.

  • And just like that, the project fell through, and thousands of trees withered away and died.

  • But in January 2015, the UAE Cabinet approved the UAE Green Agenda for 2030,

  • aimed at building a green economy.

  • Plants are this miracle worker in terms of pulling carbon dioxide.

  • So you see a lot of engineering approaches to think about how we pull greenhouse gases

  • out of the atmosphere, but plants by themselves are one of the best tools that we have.

  • The UAE is not alone in its quest to green the desert.

  • Other countries like China have followed the same path, as seen in a desert called Kubuqi

  • in the country's Inner Mongolia Autonomous Region.

  • In 1988, a Chinese company partnered with the Beijing government to build solar farms

  • and other renewable energy projects.

  • Three decades later and one third of Kubuqi is green, preventing dunes from encroaching on farms.

  • The United Nations Environment Programme estimated the Kubuqi project cost 1.8 billion dollars over 50 years.

  • Beijing is a proponent of cloud-seeding technology.

  • They used it to manipulate weather to protect farming areas and to guarantee clear skies for key events.

  • The UAE performs around 1,000 hours of cloud seeding to enhance rainfall in just one year.

  • And it's all controlled out of this building, the National Center of Meteorology in Abu Dhabi,

  • where they track the whole process.

  • We met with a cloud seeding expert to explain how the seeding process works.

  • We wait for the forecast when we have a good chance for clouds, we send the aircrafts to that location.

  • It goes under the cloud, in the first stage of the cloud there is good updraft at that time, it can release all

  • the salt and, with a good updraft, it goes inside the cloud and start to

  • condensate and the droplets become bigger and start to rain.

  • The centre manufactures a salt substance that helps enhance rainfall.

  • They put them in what they callflares.”

  • We also spoke to one of the weather forecasters.

  • He explains how the operations work.

  • We alert our pilots and tell them when to be at the airports.

  • So, as expected, we wait for the clouds to appear on the radar.

  • We have our pilots talking to us.

  • Le me know if there's any updrafts in your area.

  • This is a sample plane here at the National Center of Meteorology,

  • but the real planes fly out from the runways in Al Ain.

  • We have around 110 weather stations.

  • It gives us metrological data every 15 minutes.

  • The information on the screens tracks wind, speed and direction, while satellite imagery

  • monitors clouds to track fog and dust.

  • Anything passing above the country we will see it from the satellite,

  • especially the clouds.

  • And this is the map of the UAE.

  • But is the UAE seeing results from their efforts over the years

  • to create a greener country?

  • So we have different ways of either increasing the water or saving the water.

  • We have desalination, we have using plantation that doesn't take much water.

  • There are many ways. One of the ways cloud seeding.

  • Is there any success in terms of more greenery around the UAE because of cloud seeding efforts?

  • So the UAE is expanding on the agriculture and also we were expending too much before.

  • We have to do a plantation with the study. Plantation costs a lot of water.

  • We can control this water and not to use it as a waste.

  • According to the World Bank, climate-related water scarcity

  • will cost the region up to 6% of their GDP by 2050.

  • As we green landscapes, this results in healthier people, not only healthier landscapes.

  • Greening landscapes impacts the wellbeing, the mental health of people,

  • the physical health of people in terms of the air that they're breathing.

  • In a region expected to be most impacted by warming temperatures, the time has never been

  • more important than now to find alternate ways of maintaining life in the desert.

In the sprawling deserts of the United Arab Emirates, there are huge areas of greenery
