  • And things like vertical bifacial solar panels can work especially amazingly on grazing land that isn’t suitable for crops.

    Counter-intuitive as they may look, they actually have a number of benefits:

    1. The panels face east and west, meaning they generate peak power in the morning and evening, which corresponds to peak demand => less need for energy storage to bridge the gap between the mid-day peak in production from traditional PV and the aforementioned morning and evening demand peaks.
    2. The panels are vertical, which makes them easier and cheaper to maintain, as dust, snow, and rain naturally shed from their surfaces.
    3. The panels get less direct energy during mid-day, keeping their surfaces cooler. Turns out cooler solar panels are more efficient at converting light energy into electrical energy.
    4. The arrangement lends itself very naturally to agrivoltaics, which means you can derive more yields from a given piece of land and use less land overall than if you had segregated uses.
    5. The compatibility with agrivoltaics allows farmers to diversify their incomes streams and/or become energy self-sufficient.

  • Silvopasture is an ancient practice that integrates trees and pasture into a single system for raising livestock. Pastures with trees sequester five to 10 times as much carbon as those of the same size that are treeless while maintaining or increasing productivity and providing a suite of additional benefits. Livestock continue to emit the greenhouse gases methane and nitrous oxide, but these are more than offset by carbon sequestration, at least until soil carbon saturation is achieved.

    Silvopasture also offer financial benefits for farmers and ranchers. Livestock, trees, and other forest products, such as nuts, fruit, and mushrooms, generate income on different time horizons. And help protect farmers from risk. The health and productivity of both animals and the land improve.

    Trees in silvopasture systems provide livestock with protection from sun and wind, which can increase animal comfort and improve production. Trees can provide shade in the summer and windbreaks in the winter, allowing livestock to moderate their own temperature. Heat stress in livestock has been associated with decreased feed intake, increased water intake, and negative effects on production, reproductive health, milk yields, fitness, and longevity.[4][5]

    Certain tree types can also serve as fodder for livestock. Trees may produce fruit or nuts that can be eaten by livestock while still on the tree or after they have fallen. The leaves of trees may serve as forage as well, and silvopasture managers can utilize trees as forage by felling the tree so that it can be eaten by livestock, or by using coppicing or pollarding to encourage leaf growth where it is accessible to livestock.[1]

    Well-managed silvopasture systems can produce as much forage as open-pasture systems under favorable circumstances. Silvopasture systems have also been observed to produce forage of higher nutritive quality than non-silvopasture forage under certain conditions. Increased forage availability has been observed in silvopasture systems compared to open-pasture systems under drought conditions, where the combination of shade from trees and water uptake from tree roots may reduce drought impacts.[1]
