"For every rise of 1 °C in the global mean surface temperature, there is an annual decrease in global food production equivalent to around 4.4% of the recommended daily consumption per person, according to a 2025 Nature analysis."
"In low-lying areas such as coastal Bangladesh, climate change has been implicated in an uptick in cyclones, rising sea levels and extreme seasonal weather, damaging millions of hectares of arable land."
"Since the 1970s, the pace of climate change has nearly doubled, with Earth now warming by around 0.35 °C per decade, while 8.2% of the global population is already undernourished."
"Synthetic biology has emerged as a field offering budding solutions, using gene-editing tools to design crops that can withstand hostile conditions and recycle food waste through fungal fermentation."
Climate change is increasingly undermining food security, with a 1°C rise in global temperature leading to a 4.4% decrease in food production per person. Environmental stressors like soil salinity, drought, and extreme temperatures contribute to nearly half of global crop yield losses. In coastal Bangladesh, climate change has caused significant damage to arable land, decreasing from 9.6 million hectares in 1989 to 7.9 million in 2023. As the global population approaches nine billion, synthetic biology offers potential solutions, though challenges regarding equity and the legacy of GMOs remain.
