China's solar push linked to bird diversity losses across 2,344 counties
The global push for solar energy expansion could carry hidden biodiversity costs, according to a study across China published in the journal Science on Thursday.
China's ambitious solar energy expansion, driven by its goal to achieve net zero emissions by 2060, has been linked to a decline in bird diversity across its 2,344 counties, according to a study published in the journal Science. The research, which analyzed data from 2014 to 2023, found that more stringent solar development policies were consistently associated with moderate reductions in bird biodiversity.
The main culprit was rapid land conversion, primarily the transformation of cropland and grassland into developed areas, particularly in wealthier and non-desert regions. Both resident and migratory bird species experienced declines, although mountain species native to unsuitable habitats for solar farms were less affected. The study suggests that while the push for solar farms is compatible with greening efforts, "inferior greening" - homogeneous plantings that lack ecological quality - may exacerbate biodiversity losses.
The authors recommend directing large solar projects to locations with lower ecological conflict, conducting more thorough site assessments, and limiting land conversion in productive, habitat-rich regions.
