更为重要的是,全球变化,尤其是全球变暖会导致病原菌生态位向高纬度地区移动,这会导致高纬度地区病原菌物种丰度的增加并对粮食产量造成等同的负面影响。该研究成果以Plant pathogen infection risk tracks global crop yields under climate change为题发表在Nature Climate Change(IF=25.290)上。 在该研究中,研究人员首...
Climate change challenges efforts to maintain and improve crop production in many regions. In this Review, we examine yield responses to warmer temperatures, elevated carbon dioxide and changes in water availability for globally important staple cereal crops (wheat, maize, millet, sorghum and rice)....

Climate change's impacts on crop yields may force as many as seven million Mexicans to emigrate to the U.S. over the next 70 years, according to research published July 26 in the Proceedings of the National Academy of Sciences. The study is among the first to attempt to put hard numbers...

Deflection of sunlight could compensate for the warming induced by increased greenhouse gases. However, the effects of such geoengineering on food security are highly uncertain. Now research using high-carbon-dioxide, geoengineering and control climate s

Especially in the context of climate change, crop yields and prices of agricultural products fluctuate significantly, and have a significant impact on agricultural production through market and trade (Xie et al., 2020). In different periods, technology and inputs play different roles in agricultural...
3H). Although MYG exhibited around 30% higher yields relative to CK in the baseline climate, such benefits would, in many cases, be overshadowed by the negative effects of warming over time (Fig. 3A, C, E, G). For winter wheat, the MYG yields show only moderate change in the SSP1...
Air pollution and climate change are tightly interconnected and jointly affect field crop production and agroecosystem health. Although our understanding of the individual and combined impacts of air pollution and climate change factors is improving, the adaptation of crop production to concurrent air poll...
