Bio-geoengineering

Bio-geoengineering is a form of climate engineering which seeks to increase the solar reflectivity (or albedo) of crops by modifying physiological leaf and/or canopy traits to help reduce regional surface warming.

[2] As for near infrared wavelengths, which contribute about 50% of the total solar radiation energy at sea level, there is a negative relationship between plant hydration and reflectivity.

This, on top of the fact that this effect is less prominent at the canopy level, makes it unlikely that reflectivity of near infrared wavelengths will be modified for the purposes of bio-geoengineering.

[2] Because of its inherently low invasiveness (especially in terms of land use change and pre-existing food production systems) compared to other forms of geoengineering, bio-geoengineering has been argued to offer multiple advantages and much fewer risks.

One advantage is the fact that pre-existing infrastructure is already adequate in propagating these specific traits to large-scale crop cultivations.
