Scientists in China Halt Desert Expansion Using Ancient Bacteria.

A Novel Strategy to Combat Desertification

According to TSN.ua: Chinese researchers have pioneered a new technique to stop the spread of deserts by deploying specialized bacteria. These cyanobacteria, which have existed on Earth for over 3.5 billion years, form a robust crust on sand that helps retain moisture and supports plant life. The research was conducted near the Taklamakan Desert, where scientists treated sand plots with these microorganisms. This work is particularly significant as desertification threatens ecosystems and livelihoods worldwide.

Laboratory tests confirmed that the bio-crust created by the cyanobacteria reduces soil loss from wind by more than 90%. This finding is based on 59 years of monitoring desert land recovery, highlighting the study's importance for environmental conservation and the restoration of degraded areas. Consequently, this new method has the potential to become an effective solution in tackling issues related to deserts and desertification.

Experiments showed that the treated plots retained moisture significantly longer than adjacent bare sand, for periods of 10 to 16 months. This discovery indicates the potential of cyanobacteria in the fight against desertification. Artificially introducing these bacteria dramatically accelerates the formation of a mature ecosystem, reducing the process from decades to just a few years, which could have major ecological implications.

Implications for Ecological Restoration

This approach to combating desertification could substantially alter ecological restoration practices in regions suffering from land degradation. The use of cyanobacteria not only helps increase soil moisture but can also stimulate the recovery of biodiversity, which is critical for ecosystem stability. Implementing such technologies on a global scale could help mitigate the negative impacts of climate change and enhance the resilience of agroecosystems.
