To save bees, scientists say focus on habitat first, then pesticides
Scientists studied honeybees and mason bees in China's Yangtze River Valley. Preserving semi-natural habitats is more vital than reducing pesticides for pollinator diversity. Long-term monitoring and habitat conservation are crucial for safeguarding pollinators.

Scientists from Xi'an Jiaotong-Liverpool University conducted a study in China's Yangtze River Valley to assess the impact of habitat loss and pesticide exposure on honeybees and mason bees in rice fields. Their research, published in the Journal of Applied Ecology, revealed that preserving semi-natural habitats is more crucial than reducing pesticide use to protect pollinator diversity. Dr. Yi Zou emphasized the importance of non-crop habitats for providing essential resources and nesting sites for pollinators. The study highlighted that areas with more semi-natural habitat had increased food availability for bees. While acknowledging the significance of pesticide exposure, the researchers suggested focusing on conserving habitats over reducing pesticide use in rice fields. They stressed the need for long-term monitoring of pollinator populations and pesticide exposure to guide conservation efforts effectively. The study's findings underscore the critical role of habitat preservation in safeguarding pollinator diversity in agricultural ecosystems, particularly in regions with diverse landscapes like Chinese small-holder farms.

Protecting just 1.2% of Earth could save most-threatened species, says study
A study proposes safeguarding 1.2% of Earth's land to avert species extinction. 16,825 global sites are identified for urgent conservation, stressing the significance of protecting habitats for rare species like the peyote cactus. Governments' commitment to preserving 30% of the planet contrasts with the study's finding that only 7% of new protected areas align with critical conservation sites. Investing $29bn-$46bn over five years is necessary, achievable through methods like land acquisition and Indigenous rights expansion. Immediate action is crucial to prevent extinctions and preserve biodiversity effectively.
