아프리카의 기후 도전: 식량 생산을 보호하기 위한 전략

아프리카, 특히 사하라 사막 이남 지역의 기온 상승이 가속화됨에 따라 농업에 대한 위협이 더욱 분명해지고 있습니다. 2025년부터 2040년까지 사하라 사막 이남의 많은 국가는 전 세계 평균보다 빠른 2도의 평균 기온 상승을 경험할 것으로 예상됩니다.

이러한 우려스러운 상황으로 인해 아프리카 기후 정상회의에서 전문가들이 농작물 수확량에 미칠 잠재적 영향에 대한 논의를 시작했습니다. 이 분야의 저명한 인물인 치바카 박사는 "아프리카 국가들은 이미 농업 생산성 저하를 목격하고 있으며, 지속 가능한 연구 자금이 없다면 더 큰 손실에 직면할 수 있다"고 지적했습니다. 1961년부터 2015년까지 전 세계 생산성은 20% 감소했지만 아프리카는 40%라는 놀라운 감소율을 기록했습니다." 이러한 위기는 아프리카 농업에 대한 즉각적이고 포괄적인 개입을 요구합니다.

한 가지 핵심 초점은 수세기 동안 아프리카 기후에서 번성해온 토착 작물에 우선순위를 두는 것입니다. 치카바 박사는 수수, 기장, 카사바, 옥수수, 밀, 고구마와 같은 토종 작물을 포용하는 것이 중요하다고 강조했습니다. 게이츠 재단은 러시아-우크라이나 전쟁과 같은 국제적 사건으로 부각된 수입 의존의 위험성을 인식하고 CGIAR 시스템을 통해 이러한 아프리카 토착 식품에 대한 연구를 지원하기 위해 최선을 다하고 있습니다.

치카바 박사는 "아프리카 국가들은 사치품 수출에 우선순위를 두기보다는 국민에게 필수적인 주식 작물의 연구 개발에 더 많은 자원을 할당해야 한다"고 강조합니다. 생산하지 않는 것을 소비하고 소비하지 않는 것을 생산하는 것은 위험합니다. 아프리카는 생산한 것을 먹고 소비한 것을 생산하기 위해 노력해야 합니다."

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression Dinotefuran is known to negatively affect honeybee ( Apis mellifera ) behavior, but the underlying mechanism remains unclear. The magnetoreceptor ( MagR , which responds to magnetic fields) and cryptochrome ( Cry2 , which is sensitive to light) genes are considered to play important roles in honey bees’ homing and localization behaviors. Our study found that dinotefuran, even without direct contact, can act like a magnet, significantly altering MagR expression in honeybees. This non-contact exposure reduced the bees’ homing rate. In further experiments, we exposed foragers to light and magnetic fields, the MagR gene responded to magnetic fields only in the presence of light, with Cry 2 playing a key switching role in the magnetic field receptor mechanism ( MagR–Cry2 ). Yeast two-hybrid and BiFc assays confirmed an interactio...

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns The World Beekeeping Awards will not grant a prize for honey next year due to the “inability” to thoroughly test honey for adulteration. The announcement comes amid the rise of honey fraud in the EU, where a 2023 investigation found that 46% of 147 honey samples tested were likely contaminated with low-cost plant syrups. Apimondia, the International Federation of Beekeepers’ Associations, organizes the event at its Congress, whose 49th edition will be held in Copenhagen, Denmark, in September 2025. The conference brings together beekeepers, scientists and other stakeholders. “We will celebrate honey in many ways at the Congress, but honey will no longer be a category, and thus, there will be no honey judging in the World Beekeeping Awards. The lessons learned from Canada 2019 and Chile 2023 were that adequate testing was impossible if we are to award winning honey at the Con...

Unveiling the Canopy's Secrets: New Bee Species Discovered in the Pacific

Unveiling the Canopy's Secrets: New Bee Species Discovered in the Pacific In an exciting development for environmentalists and beekeeping experts, researchers have discovered eight new species of masked bees in the Pacific Islands, shining a light on the rich biodiversity hidden within the forest canopy. This discovery underscores the critical role bees play in our ecosystems and the pressing need for conservation efforts to protect these vital pollinators. A New Frontier in Bee Research By exploring the forest canopy, scientists have opened a new frontier in bee research, revealing species that have adapted to life high above the ground. These discoveries are crucial for understanding the complex relationships between bees, flora, and the broader ecosystem. The new species of masked bees, characterized by their striking black bodies with yellow or white highlights, particularly on their faces, rely exclusively on the forest canopy for survival. The Importance of Bee Conservation...

Bee attack claims life of newspaper distributor Newspaper distributor Pushparaja Shetty (45), who sustained severe injuries in a bee attack, succumbed to his injuries on Thursday at a hospital in Mangaluru. Pushparaja was attacked by a swarm of bees on Wednesday morning while walking at Kenjaru Taangadi under Bajpe town panchayat limits. He was immediately admitted to a hospital for treatment but could not survive the ordeal. Fondly known as ‘Boggu’ in the Porkodi area, Pushparaja was well-known for his dedication to delivering newspapers on foot to every household. He was admired for his generosity, as he often distributed sweets to schoolchildren on Independence Day using his own earnings and contributed part of his income to the betterment of society. Pushparaja was unmarried and is survived by three brothers and one sister.

New Report – Interlocked: Midwives and the Climate Crisis

New Report – Interlocked: Midwives and the Climate Crisis Earlier this year, midwives from 41 countries shared their experiences of working in communities affected by climate change through our survey, Midwives’ Experiences and Perspectives on Climate Change. Their voices shaped our new report, Interlocked: Midwives and the Climate Crisis , which highlights how midwives are already responding to the health impacts of climate disasters like floods, wildfires, and extreme heat—and why they must be included in climate action plans. What did we learn?Climate change is damaging community health: 75% of midwives reported that climate change is harming the communities they serve, with rising rates of preterm births, food insecurity, and restricted access to care during disasters like floods. Midwives are critical first responders: Midwives are often the first and only healthcare providers on the ground in crises, delivering care during wildfires, floods, and extreme heat. Midwives face signi...

Start the New Year Humming Like a Bee

Start the New Year Humming Like a Bee There are lots of opportunities to be as busy as a bee during these winter holidays. As we hustle toward the dawn of the New Year, it can be hard to notice that the natural world is actually suggesting something different for us right now. We’re past the solstice, but the winter still stretches ahead, the days are still short and the nights long. We’re being invited into a quieter, more inner-focused time. The ancient yogis were all about this inner focus. In India, for example, the Upanishads, the Sanskrit writings that accompanied the development of Hinduism — and alongside it, yoga — beginning around 800 B.C.E., went deeper than earlier texts had into philosophy and questions of being. With the goals of increased inner awareness and higher consciousness, yoga was at that time not yet as focused on the body or on asanas, as it now can tend to be. But the yogis did develop many practices to try to open the way to those goals. They discovered...

The largest “killer hornets” in the world were exterminated in the US

The largest “killer hornets” in the world were exterminated in the US The US informed that it had exterminated the worldʼs largest hornets, nicknamed "killer hornets" — they are capable of occupying a hive of honey bees in just 90 minutes, decapitating all its inhabitants and feeding their offspring to their own. This was reported by the Department of Agriculture in Washington. The hornets, which can reach five centimeters in length, were previously called Asian giant hornets, but in 2019 they were also spotted in Washington state near the Canadian border. In China, these insects killed 42 people and seriously injured 1,675. A dead northern giant hornet (below) next to a native bald hornet. According to experts, the hornets could have entered North America in plant pots or shipping containers. The hornet can sting through most beekeeper suits because it produces nearly seven times more venom than a honeybee and stings multiple times. Thatʼs why the Washington Departme...

Why the Caraways are proud to “bee” farmers

Why the Caraways are proud to “bee” farmers Bees play a vital role in our ecosystem by spreading nutrients to crops, produce, and other plants. Ron and Diane Caraway are reminded of that each day on the homestead, Boggy Branch Farms, that’s been in their family for three generations. While Ron cared for the land as a teenager, he followed in his father’s footsteps and joined the U.S. Air Force after graduating high school. He managed airplanes for 45 years as an air traffic controller. Now, Ron manages flying insects as a beekeeper—or, as he puts it, a ‘bee partner.’ “They allow me to work alongside with them and to help them in some cases, with the case of parasites or diseases and I’m able to enjoy that fruit that they provide,” explained Ron. Along with raising their handful of hives, the Caraways grow hay and produce. Above all, they want to raise awareness for the bees’ essential role in making things grow. “One of the things that I think that we overlook is—in the Wiregrass ...

Climate Crisis Claims Glacier's Vital Climate Data Archive

Climate Crisis Claims Glacier's Vital Climate Data Archive A recent study published in Nature Geoscience reveals a distressing consequence of global warming: the irreversible loss of valuable climate data stored in alpine glaciers. The research, conducted by a team led by Margit Schwikowski from the Paul Scherrer Institute (PSI), underscores the alarming rate at which glaciers are melting and highlights the implications for climate research. The study focuses on the Corbassière glacier at Grand Combin in Switzerland, where ice cores drilled in 2018 and 2020 were intended to serve as vital climate archives. However, comparing the two sets of ice cores reveals a grim reality—global warming has rendered the glacier unsuitable as a reliable climate archive. Glaciers, renowned as climate archives, encapsulate valuable information about past climatic conditions and atmospheric compositions. The fluctuating concentrations of trace substances in ice layers provide insights into historica...

Watch bees defend their nest by slapping ants with their wings

Watch bees defend their nest by slapping ants with their wings With a flick of the wing, Japanese honeybees slap away ants that try to infiltrate their hive. Ants often invade honeybee nests, seeking to steal honey, prey on eggs or kill worker bees. In defence, bees have been known to fan their wings to blow ants away. Now, researchers have documented making contact with their wings and physically batting ants out of the hive, a behaviour that hasn’t been studied before. Footage from a high-speed camera shows that guard bees, positioned near a nest’s entrance, tilt their bodies towards approaching ants and flutter their wings while pivoting away. A successful hit sends the ant flying. Many beekeepers seem unaware of this strategy, says Yoshiko Sakamoto. “I myself did not notice this behavior during my approximately 10 years of beekeeping experience,” she says. Sakamoto, Yugo Seko and Kiyohito Morii, all at the National Institute for Environment...
