People Flock to Saudi Arabia's First Int'l Tea Exhibition

Tea is one of the most consumed drinks globally after water, and it is one of the essential traditional drinks in many countries, including Saudi Arabia.

Saudis consider tea a part of their long-standing heritage after it was introduced into the Kingdom nearly a hundred years ago.

Alongside Saudi coffee, tea is a staple at all social occasions.

Saudis’ love for tea was reflected in the tremendous public turnout at the International Tea Colors, which coincides with International Tea Day.

The event was the first hosted by Saudi Arabia that celebrated tea and its baked goods.

The organizers were keen to ensure there were adequate spaces within the halls of the Riyadh International Fair to display the brands and tea products to the public.

Several events will be held on the sidelines of the exhibition, including a tasting and evaluation platform competing for the best dish of sweet and savory snacks accompanying tea.

Shivanka, a Sri Lankan who is an avid tea drinker, specializes in experimenting with tea crops of all kinds and determining their quality.

He said he has been working in this profession for nearly 20 years.

He drinks about 800 cups of tea a day to get used to its taste and distinguish between the different types to determine the best quality.

Shivanka has been working in Saudi Arabia with a company specializing in tea for nearly 15 years. He indicated that Saudis have a distinct palate in tea, so he works hard to ensure that his evaluation is accurate to provide the best possible quality.

Hamad al-Enzi stated that he has enjoyed drinking tea daily for nearly 30 years.

Enzi, touring the exhibition, said that he drinks tea daily and wanted to attend the show and learn more about tea and its types and production details.

He also wanted to learn about the different companies in Saudi Arabia that produce tea.

According to World Bank, Saudis consume eight billion cups of tea annually, and the per capita consumption of tea in the Kingdom in 2020 ranked first in the Arab world with 1.2 kilograms, exceeding consumption per capita globally by 0.2 kilograms.

A scientist guides a long tube into the mouth and down to the stomach of Thing 1, a two-month-old calf that is part of a research project aiming to prevent cows from burping methane, a potent greenhouse gas.

Paulo de Meo Filho, a postdoctoral researcher at University of California, Davis, is part of an ambitious experiment aiming to develop a pill to transform cow gut bacteria so it emits less or no methane.

While the fossil fuel industry and some natural sources emit methane, cattle farming has become a major climate concern due to the sheer volume of the cows' emissions.

"Almost half of the increase in (global) temperature that we've had so far, it's been because of methane," said Ermias Kebreab, an animal science professor at UC Davis.

Methane, the second largest contributor to climate change after carbon dioxide, breaks down faster than CO2 but is more potent.

"Methane lives in the atmosphere for about 12 years" unlike carbon dioxide which persists for centuries, Kebreab said.

"If you start reducing methane now, we can actually see the effect on the temperature very quickly."

Filho uses the tube to extract liquid from Thing 1's rumen -- the first stomach compartment containing partially digested food.

Using the rumen liquid samples, the scientists are studying the microbes that convert hydrogen into methane, which is not digested by the cow but instead burped out.

A single cow will burp roughly 220 pounds (100 kilograms) of the gas annually.

- 'Social critters' -

Thing 1 and other calves receive a seaweed-supplemented diet to reduce methane production.

Scientists hope to achieve similar results by introducing genetically modified microbes that soak up hydrogen, starving methane-producing bacteria at the source.

However, the team proceeds cautiously.

"We can't just simply cut down methane production by removing" methane-making bacteria, as hydrogen could accumulate to the point of harming the animal, warned Matthias Hess, who runs the UC Davis lab.

"Microbes are kind of social critters. They really like to live together," he said.

"The way they interact and affect each other impacts the overall function of the ecosystem."

Hess's students test different formulas in bioreactors, vessels that reproduce microorganisms' living conditions in a stomach from movements to temperature.

- More productive cows -

The project is being carried out at UC Davis as well as UC Berkeley's Innovative Genomics Institute (IGI).

IGI scientists are trying to identify the right microbe -- the one they hope to genetically alter to supplant methane-producing microbes.

The modified microorganisms will then be tested at UC Davis in the lab and in the animals.

"Not only are we trying to reduce methane emissions, but you also increase the feed efficiency," said Kebreab.

"Hydrogen and methane, they are both energy, and so if you reduce that energy and redirect it to something else... we have a better productivity and lower emissions at the same time."

The ultimate goal is a single-dose treatment administered early in life, since most cattle graze freely and can't receive daily supplements.

The three research teams have been given $70 million and seven years to achieve a breakthrough.

Kebreab has long studied sustainable livestock practices and pushes back against calls to reduce meat consumption to save the planet.

While acknowledging this might work for healthy adults in developed nations, he pointed to countries like Indonesia, where the government is seeking to increase meat and dairy production because 20 percent of children under five suffer from stunted growth.

"We can't tell them to not eat meat," he said.
