WASHINGTON — Arnong Mungoei has farmed rice in Thailand’s Khon Kaen province for half a century.  

Working land some 500 kilometers northeast of Bangkok never made her rich, but it provided a dependable livelihood.  

But since February 2022 when Russia invaded Ukraine, global geopolitical tensions and weather conditions elsewhere have upended the rice markets and by 2023, worldwide rice prices had exploded.  

Yet Arnong said she made less than she has in years. 

“The mills [that buy rice] don’t increase the price. What can I do? I bring rice there to sell. Whatever they offer us, we have to sell it. We won’t take the rice back because we had to pay for the truck,” said Arnong, 68.

In 2023, the prices of wheat and grains such as oats and corn declined 20% to 30% as stocks were replenished, according to an annual report from the Food and Agriculture Organization of the United Nations.

But according to the FAO report, rice prices remained high throughout the year due to a persistent La Niña in March, followed by an El Niño anomaly in June and India imposing restrictions on non-basmati rice in July due after a late monsoon raised fears of a production shortfall.

India’s export control removed 9 million metric tons of grain from the international market and ignited global prices. India is responsible for 40% of global rice supplies after overtaking Thailand as the world’s largest rice exporter in 2011.

The countries most reliant on India’s rice include the Philippines, Malaysia and Vietnam in Southeast Asia, and Nigeria, Ivory Coast and Senegal in West Africa.

“Rice is tough, because there are just not a lot of other suppliers,” Joseph Glauber, a senior fellow at the International Food Policy Research Institute in Washington, told Bloomberg in November, adding that India’s export-control policy leaves “a big hole to fill.”

 

The World Bank predicted, “Rice prices will remain high into 2024, assuming India maintains its export restrictions. The outlook assumes a moderate-to-strong El Niño.”

The bank’s commodity report published on Oct. 30 said rice prices had reached their highest point in the third quarter of 2023 since the 2007-2008 food crises due to the Hamas-Israel conflict and El Niño.

While India’s controls benefit its own consumers, for the billions elsewhere in Asia and in Africa who depend on a stable rice supply, continued high prices could increase food insecurity. 

In Nigeria, the cost of rice increased 61% from September through November. The U.S. Department of Agriculture forecast the nation would import 2.1 million metric tons of rice in 2024. 

In the Philippines, President Ferdinand Marcos Jr. imposed a price cap Sept. 5 after the cost of rice hit a 14-year high in September. Marcos, who blamed the soaring prices on “smugglers, hoarders and price manipulators,” removed the cap Oct. 13 as concerns over tight supply eased.

Alfie Pulumbarit, national coordinator at MASIPAG, a Philippine-based network of farmers, scientists and nongovernmental organizations working on farmer empowerment, told VOA Thai that rising food prices significantly affected the people in the island nation with “a lot of families now going hungry.”

Citing official information, Pulumbarit said that while it takes a person at least 79 pesos or about $1.50 dollars per day to survive in the Philippines, rice now costs $1.10 dollars per kilogram.

Continued Indian controls coupled with farmers “already leaving rice production in the Philippines” could lead to “a food crisis of epic proportions,” he said.

Climate is one of the key factors in analyses for rice production and price in the coming year.

 

The U.S. National Weather Service forecasts that the Northern Hemisphere, home to major rice producers like China, India, and Southeast Asia nations, will likely be affected by El Niño April through June, right around sowing season for rice across Asia.

An Asian Bank Development analysis recommends that the private sector should assume a bigger role in rice trading to help stabilize domestic production loss in importing countries. It also encourages policymakers to consider more sustainable rice production.

“Rice paddy is responsible for 12% of global methane emissions and 1.5% of global greenhouse gas emissions. In Asia, rice irrigation consumes more than half of freshwater resources,” according to the analysis.

As the COP 28 meeting at Dubai was concluding, the FAO suggested stakeholders should seek out climate-friendly cultivating techniques ranging from using fertilizers that can reduce methane emission to growing plants that create rhizobacteria, which may promote producing oxygen in soil.

Tokyo, Japan — Japan’s SLIM space probe entered the moon’s orbit Monday in a major step toward the country’s first successful lunar landing, expected next month.

The Smart Lander for Investigating Moon (SLIM) is nicknamed the “Moon Sniper” because it is designed to land within 100 meters (328 feet) of a specific target on the lunar surface.

If successful, the touchdown would make Japan only the fifth country to have successfully landed a probe on the moon, after the United States, Russia, China and India.  

On Monday, SLIM “successfully entered the moon’s orbit at 04:51 p.m. Japan time” (0751 GMT), the Japan Aerospace Exploration Agency (JAXA) said in a statement released Monday evening.  

“Its’ trajectory shift was achieved as originally planned, and there is nothing out of the ordinary about the probe’s conditions,” the agency said.

The lander’s descent toward the moon is expected to start around 12:00 a.m. Japan time on January 20, with its landing on the surface scheduled for 20 minutes later, JAXA said.  

The H-IIA rocket lifted off in September from the southern island of Tanegashima carrying the lander, after three postponements linked to bad weather.

JAXA said this month that the mission would be an “unprecedentedly high precision landing” on the moon.

The lander is equipped with a spherical probe that was developed by a toy company.

Slightly bigger than a tennis ball, it can change its shape to move on the lunar surface.

Compared to previous probes that landed “a few or 10-plus kilometers” away from targets, SLIM’s purported margin of error of under 100 meters suggests a level of accuracy once thought impossible, thanks to the culmination of a 20-year effort by researchers, according to JAXA.  

With the advance of technology, demand is growing to pinpoint targets like craters and rocks on the lunar surface, Shinichiro Sakai, JAXA’s SLIM project manager, told reporters this month.

“Gone are the days when merely exploring ‘somewhere on the moon’ was desired,” he said.  

Hopes are also high that SLIM’s exactitude will make sampling of the lunar permafrost easier, bringing scientists a step closer to uncovering the mystery around water resources on the moon, Sakai added.  

Japanese missions have failed twice — one public and one private.  

Last year, the country unsuccessfully sent a lunar probe named OMOTENASHI (outstanding moon exploration technologies demonstrated by nano semi-hard impactor) as part of the United States’ Artemis 1 mission.   

In April, Japanese startup ispace tried in vain to become the first private company to land on the moon, losing communication with its craft after what it described as a “hard landing.”

Paris — Even as human-caused climate change threatens the environment, nature continues to inspire our technological advancement.

“The solutions that are provided by nature have evolved for billions of years and tested repeatedly every day since the beginning of time,” said Evripidis Gkanias, a University of Edinburgh researcher. 

Gkanias has a special interest in how nature can educate artificial intelligence.

“Human creativity might be fascinating, but it cannot reach nature’s robustness — and engineers know that,” he told AFP.

From compasses mimicking insect eyes to forest fire-fighting robots that behave like vines, here’s a selection of this year’s nature-based technology.

Insect compass

Some insects — such as ants and bees — navigate visually based on the intensity and polarisation of sunlight, thus using the sun’s position as a reference point. 

Researchers replicated their eye structure to construct a compass capable of estimating the sun’s location in the sky, even on cloudy days.

Common compasses rely on Earth’s weak magnetic field to navigate, which is easily disturbed by noise from electronics.

A prototype of the light-detecting compass is “already working great,” said Gkanias, who led the study published in Communications Engineering. 

“With the appropriate funding, this could easily be transformed into a more compact and lightweight product” freely available, he added. 

And with a little further tweaking, the insect compass could work on any planet where a big celestial light source is visible.

Water-collecting webs

Fabric inspired by the silky threads of a spider web and capable of collecting drinking water from morning mist could soon play an important role in regions suffering water scarcity.

The artificial threads draw from the feather-legged spider, whose intricate “spindle-knots” allow large water droplets to move and collect on its web.

Once the material can be mass produced, the water harvested could reach a “considerable scale for real application”, Yongmei Zheng, a co-author of the study published in Advanced Functional Materials, told AFP.

Fire-fighting vines 

Animals aren’t the only source of inspiration from nature.

Scientists have created an inflatable robot that “grows” in the direction of light or heat, in the same way vines creep up a wall or across a forest floor. 

The roughly two-meter-long tubular robot can steer itself using fluid-filled pouches rather than costly electronics.  

In time, these robots could find hot spots and deliver fire suppression agents, say researchers at the University of California, Santa Barbara.   

“These robots are slow, but that is OK for fighting smoldering fires, such as peat fires, which can be a major source of carbon emissions,” co-author Charles Xiao told AFP. 

But before the robots can climb the terrain, they need to be more heat-resistant and agile.

Kombucha circuits

Scientists at the Unconventional Computing Laboratory at the University of the West of England in Bristol have found a way to use slimy kombucha mats — produced by yeast and bacteria during the fermenting of the popular tea-based drink — to create “kombucha electronics.”

The scientists printed electrical circuits onto dried mats that were capable of illuminating small LED lights.   

Dry kombucha mats share properties of textiles or even leather. But they are sustainable and biodegradable, and can even be immersed in water for days without being destroyed, said the authors.

“Kombucha wearables could potentially incorporate sensors and electronics within the material itself, providing a seamless and unobtrusive integration of technology with the human body,” such as for heart monitors or step-trackers, lead author Andrew Adamatzky and the laboratory’s director, told AFP.

The mats are lighter, cheaper and more flexible than plastic, but the authors caution that durability and mass production remain significant obstacles.

Scaly robots

Pangolins resemble a cross between a pine cone and an anteater. The soft-bodied mammals, covered in reptilian scales, are known to curl up in a ball to protect themselves against predators. 

Now, a tiny robot might adapt that same design for potentially life-saving work, according to a study published in Nature Communications.

It is intended to roll through our digestive tracts before unfurling and delivering medicine or stopping internal bleeding in hard-to-reach parts of the human body. 

Lead author Ren Hao Soon of the Max Planck Institute for Intelligent Systems was watching a YouTube video when he “stumbled across the animal and saw it was a good fit.”

Soon needed a soft material that wouldn’t cause harm inside the human body, with the advantages of a hard material that could, for example, conduct electricity. The Pangolin’s unique structure was perfect.

The tiny robots are still in their initial stages, but they could be made for as little as 10 euros each. 

“Looking to nature to solve these kinds of problems is natural,” said Soon. 

“Every single design part of an animal serves a particular function. It’s very elegant.”
