Animal feed is vital for the global food security, but it deeply affects the environment given the amount of greenhouse emissions emitted during its production and processing. Yet, new innovations and techniques could help provide sustainable and clean solutions in this field.

New feed source

The King Abdullah University of Science and Technology (KAUST) has collaborated with the Ministry of Environment, Water, and Agriculture (MEWA) to produce a new source of animal feed in the KSA.

The new project, which aligns with Vision 2030 and the Saudi Green Initiative's focus on food security, aims at developing new techniques to produce the highest quality of algae protein used as feed for animals such as fish and poultry. The project supports producing local raw material for animal feed and reduces the reliance on imported raw materials. This could help establish a sustainable animal feed industry in Saudi Arabia.

“The microalgae project aligns with the kingdom’s Vision 2030 and the Saudi Green Initiative, and will bring environmental, social, and economic benefits not only for Saudi Arabia, but for the whole world,” said Dr. Ali Al Shaiki, CEO of National Fisheries Development Program.

The project, known as Development of Algal Biotechnology in the Kingdom of Saudi Arabia- (DABKSA), is overseen by MEWA’s National Fisheries Development Program (NFDP) located on the KAUST campus. The project director in Dr. Claudio Grünewal, joined KAUST in October 2021 from Swansea University in Wales, bringing extensive experience in marine microalgal production, with the engineering expertise needed to design, build and operate high-scale aquaculture installations. Grünewald has delivered several microalgae industrial size projects in different countries such as Spain, Chile, Japan and the United Kingdom.

Pilot program

Phase one consisted of constructing an 870 m2 -experimental facility aimed at studying the feasibility of the high-protein algae. Opened on March 22, the facility provides documented data on the productivity of algae during the first year. The data will be used to assess the feasibility, economic benefits, and sustainability of the project.

Algae grows in both seawater and fresh water, driven by sunlight’s reaction with nitrogen, phosphorus and carbon dioxide. In the DABKSA project, algae rich in protein, oils and carbohydrates are planted in systems of outdoor ponds (raceways) and closed tubes (photobioreactors). The concentrated paste is made using a liquid culture (usually conducted in testing tubes), and then it’s freeze dried to make the powdered biomass that will be included in feed for animals.

The project has several environmental benefits, and the limited sources such as soil, water, and energy are being used in growing animals and their feed. It’s also expected to help reduce greenhouse emissions usually produced by the conventional animal feeds.

Algae-based techniques can also contribute to reducing environmental impacts. Among the proposed solutions is feeding the fish the algae-based food, and then reuse the water from the tanks used to grow the fish to grow more algae, which could lead to a circular economy. Algae can grow along the Saudi coasts (3,400 kilometers), the Red Sea, and the Gulf.

Production phase

Once feasibility is demonstrated in Phase I, the Algal Biotechnology project will proceed to Phase II, which involves designing and building a larger aquaculture and algae plant. The target tonnage of dry weight biomass is expected to reach approximately 1.5 – 2 tons in the first year, and a larger yield in Phase II (late 2023-24) — between 50 and 100 tons, when the plant expands to a four-hectare facility. A future goal of DABKSA is to apply multi-trophic aquaculture approaches to the Red Sea Project and NEOM, among other in-Kingdom projects.

KAUST is a center for wide-scale research on algae in the Kingdom. In the past two years, the university has preserved the main talents and equipment to accelerate – not only the animal feed project related to the food security initiative and the Saudi Vision 2030 – but also the use of algae in the production of tires, perfumes, and pharmaceutical drugs.

The university is also the only laboratory experimenting with algae-based applied biotechnology in the Arabian Peninsula, working on identifying local algae strains, their different behaviors and tolerance of external environmental factors. KAUST has also built a library featuring the local strains of algae of commercial value to the Kingdom of Saudi Arabia.

Among the project’s team members is Dr. Kyle Lauersen, KAUST assistant professor and algae expert, who helps professor Grünewald developing strategies to train future generations of algae experts and help them apply new techniques across the Kingdom.

"I truly believe that the Kingdom has a competitive advantage to run industrial algal cultivation along the Red Sea coast with its flat land, CO2 sources, and year-round solar irradiation," Grünewald said.

Rain Further Batters Storm-Hit Portugal, Thousands Evacuated

More ‌heavy rain flooded several rural areas in the north of storm-battered Portugal on Wednesday, leaving levees at risk of bursting around the medieval city of Coimbra and forcing authorities to evacuate about 3,000 residents as a precaution.

A succession of deadly storms has hammered mostly central and southern parts of the country since late January, blowing roofs off houses, flooding several towns and leaving hundreds of thousands without electricity for days. At least 15 people have died as a consequence of the storms, including indirect ‌victims.

As the ‌storms let up this week, a weather ‌phenomenon ⁠known as an "atmospheric river" - ⁠a wide corridor of concentrated water vapor carrying massive amounts of moisture from the tropics - brought new downpours, affecting the north to a greater extent.

RISK OF DAM OVERFLOWING

Municipal authorities in Coimbra ordered the precautionary evacuation late on Tuesday of around 3,000 people most at risk from the River Mondego bursting its banks, ⁠and the operation was still under way on ‌Wednesday, with police making door-to-door checks ‌and bussing residents to shelters.

Regional Civil Protection official Carlos Tavares ‌said on Wednesday the situation could worsen between late Wednesday ‌and midday Thursday, as the rain could cause the Aguieira dam, 35 km northeast of Coimbra, "to overflow, sweep away levees and trigger further flooding".

Part of Coimbra's ancient city wall, on a hillside in one ‌of Europe's oldest university towns and a UNESCO World Heritage site, collapsed, shutting the road below ⁠and forcing ⁠the closure of the municipal market, the city hall said.

Prime Minister Luis Montenegro was due in Coimbra to oversee the emergency response after Interior Minister Maria Lucia Amaral resigned following criticism from opposition parties and local communities over what they described as the authorities' slow and failed response to devastating Storm Kristin two weeks ago.

In central Portugal, just across the River Tagus from Lisbon, authorities evacuated the village of Porto Brandao due to the risk of landslides, and around 30 people were removed from their homes after a landslide in the neighboring beachside area of Caparica.

From Argentina to Australia to South Africa, record heat and raging wildfires are rampaging through the Southern Hemisphere at the start of 2026, with scientists predicting that even more extreme temperatures could lie ahead - and possibly another global annual high - after three of the hottest years on record.

In January, a record-setting heat dome enveloped Australia, sending temperatures near 50 degrees C (122 degrees F) while heat and catastrophic wildfires gripped parts of South America, setting remote parts of Argentina's Patagonia ablaze and killing 21 people in coastal towns in Chile. In addition, South Africa has been experiencing its worst wildfires in years.

The extremes are occurring even as the world remains under the cooling influence of a weak La Nina, a climate cycle marked by cooler waters in the central and eastern Pacific that began in December 2024. Despite this moderating factor, temperatures are reaching record highs in various locales.

"This means the effect of human-caused climate change is overwhelming natural variability," said climate scientist Theodore Keeping of Imperial College London and the international research collaboration World Weather Attribution, who specializes in research on wildfires and extreme heat.

"As we transition into a neutral or even El Nino phase, we'll expect the incidence of extreme heat events around the world to be further amplified," Keeping added.

El Nino typically has the opposite effect of La Nina, warming the central and eastern Pacific and boosting global temperatures.

This year is forecast to be about 1.46 degrees C (2.6 degrees F) above pre-industrial levels, which would make it the fourth consecutive year to be higher than 1.4 degrees C (2.5 degrees F) above pre-industrial levels, according to Adam Scaife, head of the long-range prediction at the United Kingdom's national weather ‌and climate service.

The 2015 ‌international climate treaty, known as the Paris Agreement, aimed to keep warming below 1.5 degrees C (2.7 degrees F) above pre-industrial levels.

"If a big ‌El Nino ⁠were to develop ⁠quickly in 2026 then it's still possible 2026 could be a record," Scaife said. The World Meteorological Organization said last month that the past three years were the warmest on record.

FIRE RAGES FROM WOODS TO WATER

While most wildfires are caused by human activity, they are also a natural part of many ecosystems. Persistent heat, drought and extreme temperatures, however, are turning once-manageable fires into increasingly uncontrollable and destructive events.

Many ecosystems are not adapted to such hot, dry conditions, allowing fires to grow larger and more intense, often causing permanent damage, Keeping said.

The fires that burned through Argentina's Los Alerces National Park illustrate the shift, according to meteorologist Carolina Vera of the Center for Ocean and Atmospheric Research at the University of Buenos Aires.

The park, a UNESCO World Heritage site, is home to trees that have lived more than 3,000 years.

Local officials determined that a lightning strike caused the fire. The blaze initially was under control. But Vera said a heat wave and strong winds caused it to spread about 20 km (12 miles) in a single day, making it the worst wildfire there ⁠in two decades.

The region has been drought-stricken since 2008. Temperatures during the first two weeks of January were about 6 degrees C (11 degrees F) above ‌normal.

"These fires used to burn themselves out and form part of the forest's natural dynamics," Vera said.

"This is an example of ‌how climate change can alter a natural fire, because it appeared to be caused by lightning," Vera said.

There are no towns in that remote area.

Fires erupted in the southern part of neighboring Chile later in January and ‌crossed into the greater Concepcion area, the country's third-largest metropolitan region, destroying hundreds of homes and killing 21 people in coastal communities.

Keeping said the blazes mirrored recent disasters in places such as ‌Los Angeles, Athens and the Hawaiian island of Maui.

"Where there's been the greatest loss of life, it almost always comes down to evacuation being difficult or impossible," Keeping said. "That's particularly true in regions affected by strong downslope winds toward the coast."

WHIRLWINDS OF FIRE

About 80% of Punta de Parra, a small coastal town in southern Chile surrounded by hills and forests, was destroyed.

Punta de Parra residents said they had little time to evacuate. Doralisa Silva, 34, said she heard about a fire in a nearby community the night the blaze reached the town.

"Out of nowhere, the forest started burning and all the houses caught fire," Silva said. "The fire was on us in the blink ‌of an eye. There was nothing we could do."

Silva said her family was among the last to try to flee because they had no vehicle. Silva said flames blocked their exit as embers rained down as she and her partner Hermes Barrientos fled with their ⁠2-year-old daughter.

Barrientos said winds of nearly 70 km ⁠per hour (43.5 mph) whipped through the area, creating whirlwinds of fire that spread to the beach and trapped residents. The family and others eventually found refuge in a large dirt field at the center of town, and spent the night watching their community burn.

A FUTURE FILLED WITH FIRES

Record-breaking heat in southeastern Australia has also fueled the country's worst fires since the deadly 2019-2020 season, when 33 people were killed.

In addition, the 2025-2026 fire season has been the most severe in South Africa in a decade, according to officials, killing wildlife and hitting tourist destinations such as Mossel Bay and Franschhoek.

"The hot, dry and windy conditions that drive the most extreme wildfires are becoming more intense and more likely," Keeping said. "And it's happening all around the world."

The Southern Hemisphere has warmed by about 0.15 to 0.17 degrees C (0.27 to 0.30 degrees F) per decade since the 1970s, compared to 0.25 to 0.30 degrees C (0.45 to 0.54 degrees F) in the Northern Hemisphere - largely because its vast oceans absorb heat more slowly and because of Antarctic meltwater.

Still, southern land masses are now warming at similar rates to northern land masses, and contrasts between warming land and cold meltwater can intensify weather patterns, leading to prolonged heat waves, droughts or flooding.

Keeping said adaptation is critical, including authorities managing vegetation near cities and developing effective evacuation plans, and builders using fire-resistant materials. Wildfires are inflicting mounting economic damage. A 2026 report by insurance broker Aon estimated global insured wildfire losses at $42 billion in 2025, up from an average of $4 billion annually between 2000 and 2024. The Los Angeles fires last year were the costliest on record.

Swiss Re, the world's second-largest reinsurer, found that wildfires accounted for about 1% of global insured losses from natural disasters before 2015, but now represent 7%, with economic losses linked to fires rising by about $170 million a year since 1970.

"You actually cannot stop a lot of these really large intense wildfires. They're simply too big," Keeping said.

The most important way forward, Keeping said, is to "have a serious conversation about limiting future climate change to prevent this issue from worsening."

Noise pollution is affecting bird behavior across the globe, disrupting everything from courtship songs to the ability to find food and avoid predators, a large-scale new analysis showed on Wednesday.

Researchers reviewed nearly four decades of scientific work and found that noises made by humans were interfering with the lives of birds on six continents and having "strong negative effects" on reproduction success.

Previous research on individual species has shown that single sources of anthropogenic noise -- such as planes, traffic and construction -- can affect birds as it does other wildlife.

But for this study, the team performed a wider analysis by pooling data published since 1990 across 160 bird species to see if any broader trends could be established.

The study, published in the journal Proceedings of the Royal Society B, found clear evidence of a "pervasive" impact of noise pollution on birds worldwide.

"We found that noise significantly impacts communication risk behaviors, foraging, aggression and physiology and had a strong effect on habitat use and a negative impact on reproduction," AFP quoted it as saying.

This is because birds rely on acoustic information to survive, making them particularly vulnerable to the modern din produced by cars, machinery and urban life.

"They use song to find mates, calls to warn of predators, and chicks make begging calls to let their parents know they're hungry," Natalie Madden, who led the research while at the University of Michigan, said in a statement.

"So if there's loud noise in the environment, can they still hear signals from their own species?"

In some cases, noise pollution interrupted mating displays, caused males to change their courtship songs, or masked messages between chicks and parents.

The study included many common species such as European robins and starlings, house sparrows, and great tits.

The response varied between species, with birds that nest close to the ground suffering greater reproductive harm, while those using open nests experienced stronger effects on growth.

Birds living in urban areas, meanwhile, tended to have higher levels of stress hormones than those outside of cities.

Some 61 percent of the world's bird species have declining populations, mostly due to habitat loss driven by expanding agriculture and logging, the International Union for Conservation of Nature said in October.

The study authors said that noise pollution was an "underappreciated consequence" of humanity's impact on nature, especially compared to biodiversity loss and climate change.

But some relatively simple fixes could make a big difference for birds, they said.

Madden told AFP that shifting from noisier cars and landscaping tools such as mowers and leaf blowers to electric-powered alternatives was one idea.

Another could be "running machinery outside peak breeding seasons, avoiding activity when birds are migrating through an area, or shifting construction away from habitats that support vulnerable species", she added.

Buildings could also be adapted to muffle sound in the same way they are constructed to improve visibility and minimize bird collisions, said the study's senior author Neil Carter, from the University of Michigan.

"So many of the things we're facing with biodiversity loss just feel inexorable and massive in scale, but we know how to use different materials and how to put things up in different ways to block sound," he said.
