Part 2: Solutions for #ClimateChange: #Agrivoltaics

(1/8)
Combining the new solar-panel-above fields method* with ancient raised-field #WaruWaru #farming #technology could facilitate #WaterConservation and management, raise yields, reduce #fertilizer concentration, and reduce #erosion.

The solution to our current #drought problems in many areas might have been with us for 2,300 years at least, probably first developed by the #Tiahuanaco culture of the #Andean...

...highlands of #Bolivia + #Peru.
Raised-field agriculture has also been used in countries like #China, #Mexico + #Morocco.

#WaruWaru also stems #desertification + creates a cooling (+warming during the night) #microclimate when combined w/ the #SolarPanels, similar to the #irrigated #gardens created by the Muslims, e.g. in the #Alhambra in #Andalucia. In combination with the solar panels. Jointly with the building of #Roman type #cisterns, #agriculture might even be extended to years..

...without rainfall for some time.

I am not an engineer, but it seems quite logic that the reflective capabilities of the
#SolarPanels will also protect the organic #soil from #erosion by rain, sun, and to some degree, wind.

After some interest in the 1960’s through 1980s and early 2000’s, a 2019 Master thesis from #Italy with the chief aim of #WaterConservation and management takes aim to solve South American cities’ recurring #flood problems using #WaruWaru:

Whereas #WaruWaru (also called #camellones in #Peru) was developed for mountain #agriculture, the author Beatrice Salinetti, like me, seems to see an application for many arid regions on all continents.

#AppliedEnergy:

"..putting agriculture under solar installations—is a good way to maximize land use. It also makes the #SolarPanels *last longer*...
Solar panels mounted 4 meters above a #soybean crop were connected to temperature reductions of up to *10* degrees Celsius, the study found, compared to..."
