Global ecosystem water use efficiency refers to the ratio between the amount of carbon assimilated by plants through photosynthesis and the amount of water lost through evapotranspiration.
It's a critical indicator of how efficiently ecosystems utilize water to produce carbon-rich biomass, impacting their overall productivity and health.
Global ecosystem water use efficiency, the carbon assimilation to water evapotranspiration ratio, has experienced a halt in its increase since 2001.
This phenomenon is due to a rising vapour pressure deficit.
The stalled water use efficiency increase has led to the suppression of global ecosystem photosynthesis.
Photosynthesis is a crucial process for the health of ecosystems.
The study emphasizes that this trend highlights a way in which the negative effects of climate warming can undermine reliance on nature-based climate solutions.
Nature-based climate solutions are vital strategies to achieve carbon neutrality.
The disruption in ecosystem photosynthesis could impact the effectiveness of these solutions.
Carbon neutrality, also referred to as climate neutrality, is a state in which the net release of carbon dioxide (CO2) into the atmosphere is balanced by an equivalent amount of carbon removal or reduction.
It is a critical concept in addressing climate change and achieving sustainability.
