On the craggy rocks on northwestern Spain's treacherous Costa da Morte (Death Coast), wetsuit-clad fishermen dodge crashing waves as they pick barnacles, a prized Christmas delicacy facing decline due to climate change and other factors.

Fetching up to 200 euros ($208) per kilogram (2.2 pounds) during the holiday season, the gooseneck barnacle from the Galicia region has long been treasured by Spaniards for both its flavor and difficulty to harvest.

However, the rise in sea temperatures driven by climate change has severely affected barnacle habitats, as they thrive in icy waters. A recent study by the University of Vigo also linked changing wave patterns to lower quality in the shellfish.

Israel Martinez, an auctioneer in the A Coruna fish market, said that there used to be double or triple the number of barnacles just 10 years ago.

Despite state regulations - such as limiting daily harvests to 7 kg per fisherman - illegal fishing has surged due to the barnacles' high value.

Licensed percebeiros, or barnacle pickers, have called for increased policing of the coast to deter poachers.

Their job is classified as a risky profession due to the adverse work conditions.

"The percebeiro trade on the Costa da Morte is dying. This is due to climate change, absurd laws, illegal fishing and a lack of workers," 36-year-old Roberto Vidal, who started out as a percebeiro at 16, told Reuters.

He said there used to be between 100 and 200 percebeiros in his town of Corme. Now, there are around 30.

Fellow percebeiro Serafin Rodriguez said that future generations would be unable to follow in his footsteps due to declining barnacle populations.

The King Abdullah University of Science and Technology (KAUST) has been developing a new robotic system designed to automate date palm harvesting, SPA reported.
According to a KAUST press release, the system aims to revolutionize the agriculture industry and establish Saudi Arabia as a leader in agriculture innovation. The research, led by KAUST Assistant Professor Shinkyu Park, focuses on automating key processes in date farming, such as harvesting, pollination, and tree maintenance through AI-powered robotics, and promises to yield larger quantities of more nutritious dates.
Park's "robotic farmers" solution combines robotics for reliable farming and AI for greater efficiency. The robotic arms of the system will be able to move as quickly as a human farmer while precisely picking each date without damage to itself or the fruit. Equipped with high-precision visual sensors, the robotic farmers can identify individual dates, flowers, and tree structures to perform tasks such as harvesting, spraying, and pruning, ensuring tree health, productivity, and longevity while reducing the risk of pest infestations and diseases.
Field trials are scheduled to begin during the 2025 harvest season, with full operational capability expected within three years. Park suggested that a Robots-as-a-Service (RaaS) model could allow smaller farmers to access the technology without the burden of purchasing the robots outright.
The project is one of many at KAUST that will benefit date farming and food security. Such projects provide Saudi Arabia an advantage not only in agricultural technology but also in agricultural expertise, as leaders in farming and robotics are drawn to the region, while laborers will be the first to engage with the new technologies developed by Park and his team, according to the release.
"I am excited that this initiative extends beyond engineering solutions and cultivates research and development opportunities for local talent, contributing to the long-term sustainable educational and economic growth of the Kingdom," he said.
