Kashmir’s Saffron Growers Experiment with Indoor Farming as Climate Pressures Mount

Tucked in a valley beneath the snow-capped Himalayas of the Indian Kashmir region is the town of Pampore, famed for its farms that grow the world's most expensive spice - the red-hued saffron.

This is where most of saffron is farmed in India, the world's second-largest producer behind Iran of the spice, which costs up to 325,000 rupees ($3,800) a kg (2.2 pounds) because it is so labor-intensive to harvest.

Come October, the crocus plants begin to bloom, covering the fields with bright purple flowers from which strands of fragrant red saffron are picked by hand, to be used in foods such as paella, and in fragrances and cloth dyes.

"I am proud to cultivate this crop," said Nisar Ahmad Malik, as he gathered flowers from his ancestral field.

But, while Malik has stuck to traditional farming, citing the "rich color, fragrance and aroma" of his produce through the years, some agrarian experts have been experimenting with indoor cultivation of the crop as global warming fears increase.

About 90% of India's saffron is produced in Kashmir, of which a majority is grown in Pampore, but the small town is under threat of rapid urbanization, according to the Indian Council of Scientific & Industrial Research (CSIR).

Experts say rising temperatures and erratic rainfall pose a risk to saffron production, which has dropped from 8 metric tons in the financial year 2010-11 to 2.6 metric tons in 2023-24, the federal government told parliament in February, adding that efforts were being made to boost production.

One such program is a project to help grow the plant indoors in a controlled environment in tubes containing moisture and vital nutrients, which Dr. Bashir Ilahi at state-run Sher-e-Kashmir University of Agricultural Sciences said has shown good results.

"Growing saffron in a controlled environment demonstrates temperature resistance and significantly reduces the risk of crop failure," said Ilahi, standing in his laboratory between stacks of crates containing tubes of the purple flower.

Ilahi and other local experts have been helping farmers with demonstrations on how to grow the crocus plant indoors.

"It is an amazing innovation," said Abdul Majeed, president of Kashmir's Saffron Growers Association, some of whose members, including Majeed, have been cultivating the crop indoors for a few years.

Manzoor Ahmad Mir, a saffron grower, urged more state support.

"The government should promote indoor saffron cultivation on a much larger scale as climate change is affecting the entire world, and Kashmir is no exception," Mir said.

Scientists have detected the "fingerprints" of a black hole's event horizon -- the boundary from which nothing can escape -- for the first time, according to research published on Wednesday.

The discovery was made by studying ripples in space-time called gravitational waves that were created when two black holes violently smashed into each other.

A black hole's event horizon is known as the "point of no return" because not even light can avoid being swallowed into its darkness.

This has made them incredibly difficult to learn anything about.

However, there is one event of such cataclysmic violence that it could offer a chance to glimpse this extreme phenomenon -- when two black holes merge into one.

When this cosmic death spiral occurs, it shoots gravitational waves across the universe which scientists have been detecting for the last decade.

For the new research published in Nature, an international team of researchers analyzed data from the strongest gravitational wave ever recorded, known as GW250114, detected by the LIGO observatory in January 2025.

By isolating the last burst of waves -- known as "direct waves" -- from this black hole merger, the scientists said they were able to extract information from closer to an event horizon than ever before.

"This black hole horizon concept normally appears in science fiction," lead study author Sizheng Ma of the Perimeter Institute for Theoretical Physics in Canada told AFP.

"But now we are really able to touch the region around the horizon with gravitational data," he added.

"Sometimes I cannot believe this is really happening."

- Causing a stir -

The last stage of two black holes merging is like a spoon stirring a glass of water, Sizheng Ma explained.

The resulting swirl in space creates the ripple of gravitational waves that travel at the speed of light in all directions.

If the metaphorical spoon is stirring close enough to the black hole's event horizon, "this offers us a chance to decode the physics around that region", Sizheng Ma said.

By supporting the theory of general relativity, the results "proved that Einstein was correct again," he added.

The scientists emphasized that more research was needed to decipher what can be gleaned about event horizons using this method.

But they did detect information about how black holes twist space around themselves as they rotate -- a phenomenon known as "frame dragging".

"This is similar to pushing a glass into a table and twisting it, so that the tablecloth winds up around it," Maximiliano Isi, a gravitational wave astrophysicist at Columbia University, told AFP.

In the future, the team of scientists hope to find signs of tiny changes known as quantum fluctuation.

"In this way, we can really probe this near horizon region to look for a new physics," including searching for a deviation from general relativity, Sizheng Ma said.

- Reaction mixed -

Experts not involved in the study urged caution.

Francesco Sannino, an Italian theoretical physicist who studies black holes, told AFP it was "compelling analysis" but needed to be checked by other researchers.

Still, it was "striking" that the scientists were able to show that gravitational waves carried the event horizon's "fingerprints," he said.

The astrophysicist Isi described the work as "tantalizing".

"More generally, understanding the physics of black holes and their mergers is important as it might shed light on how space and time are woven together at a more fundamental level," he told AFP.

Sean McWilliams, an astrophysicist at West Virginia University, was skeptical that the gravitational wave frequency analyzed by the scientists was actually "dictated" by the event horizon.

For this reason, "the actual observed signal doesn't really tell us anything about the horizon or the other properties directly related to it", he told AFP.

Sizheng Ma said McWilliams's statement was "not correct," suggesting he had conflated two different aspects in the paper.

"There is often considerable resistance and criticism in the early stages of promoting a new concept," he said, adding he is working on another paper to "clarify these confusions and possible misinterpretations".

A large asteroid that will zoom harmlessly past Earth on Saturday will be visible to stargazers using a small telescope or large binoculars, the European Space Agency announced Wednesday.

The asteroid will come within 2,560,000 kilometers of Earth at 1114 GMT on Saturday, which is more than six times the distance between the Earth and the Moon.

Called (152637) 1997 NC1, the asteroid will be speeding along at nearly nine kilometers a second, posing no threat to Earth as any chance of an impact has been ruled out.

Discovered in 1997, the asteroid is estimated to be between 750 and 1,650 meters wide, according to calculations based on how much sunlight it reflects.

However other estimates suggest it could be smaller, AFP quoted the ESA as saying in a statement.

"A close approach to Earth by an object this size only occurs every few years, although this time the bright nearby Moon might impede its observability at closest approach," Juan Luis Cano of the ESA's Planetary Defense Office said in a statement.

For stargazers with telescopes or binoculars, the asteroid will be visible in parts of the Northern Hemisphere as it approaches, almost everywhere as it speeds past Earth, and only from the Southern Hemisphere as it departs.

But this depends if people are in areas of the world where the sky is dark enough as it passes.

Singapore, Indonesia, Malaysia and Brunei face a high risk of severe haze this year due to hot and dry weather conditions, biofuel demand and economic pressures, a research institute said Wednesday.

The Singapore Institute of International Affairs said it was the second time it had issued a red risk rating since launching its Haze Outlook report in 2019. The previous red risk rating was in ⁠2023, Reuters reported.

Here are some ⁠details:

August to September is the peak danger period for haze in the Southeast Asian region, driven by the El Niño and Indian Ocean Dipole weather phenomena, the report said.

The ⁠return of El Niño is expected to create a longer and stronger dry season at a time when fire preparedness could be adversely affected by economic uncertainty and cost pressures.

The SIIA said rising costs of fertilizer and fuel as a result of the Iran war could lead to unsustainable activity such as the use ⁠of ⁠fire rather than machinery to clear land and dispose of waste.

Land use could also intensify as demand for biofuels rises due to energy supply disruptions.

"This trend will continue even if the US-Iran agreement holds, as countries now want energy independence," said SIIA associate director Khor Yu-Leng.

ASEAN cooperation and sustainable land management will be critical to reducing risks, the report said.
