‘Sweet spot’ where modules produced the most energy and provided optimal growth conditions for the crop

Adaptive solar shade system means horticulturalists can smell the roses DECEMBER 8, 2020 MARIAN WILLUHN, PV Mag Researchers have modelled the effects of various PV module arrangements on a greenhouse used for rose growing in Iran’s Shiraz region. The team determined a ‘sweet spot’ where modules produced the most energy and provided optimal growth conditions for the crop. Researchers claim to …

Soil respiration is stimulated by climate warming: Temporal changes in global soil respiration since 1987

A new study on soil respiration (the release of carbon from soil) finds that rates increased between 1987 and 1999, but remained unchanged between 2000 and 2016. Soil respiration is “stimulated by climate warming”, but according to the paper, the “magnitude and dynamics of such stimulations” is still highly uncertain. The steady rate of soil respiration from the year 2000 …

Solar park built on rough wooden structures in France

French cooperative Céléwatt and engineering company Mécojit are building a new, 250 kW solar park in southwestern France. The solar panels are installed on a raw wood structure, sourced from the surrounding forests, to promote local employment and a regional natural resource. NOVEMBER 16, 2020 GWÉNAËLLE DEBOUTTE Some 600 oak wooden structures were used in the solar plant. Image: CéléWatt Share …

Combining solar and agriculture can increase the productivity of arable land by up to 60%: Enel Green Power is doing it in the US

November 20th, 2020 by Steve Hanley  Often, solar installations compete with agriculture for arable land, which has led many researchers and energy developers to seek ways to combine the two so land can remain in productive use while also providing solar energy. Germany’s Frauhofer ISE has been a leader in this area and determined that combining solar and agriculture can increase the productivity of …

Why Democrats Keep Losing Rural Counties Like Mine

Nov/Dec 2020 I’m the chair of the local Democratic Party in a Wisconsin county that Donald Trump won. It wasn’t for a lack of progressive organizing. It was because national Democrats have failed communities like mine. The real story is that rural people feel our way of life is being sold off. We see the wealth of our sweat and …

The largest 1% of the world’s farms operate 70% of farmland and form the core of production for the corporate food system, amid increasing concentration of power and land inequality

The report outlines a number of possible steps: democratize land governance; strengthen land-related regulation; invest in well-functioning land registries; strengthen transparency and monitoring of land holdings; legally enforce responsible corporate practice; protect common and customary rights; recognize and protect women’s land rights (and Indigenous land rights); respect and strengthen civil society institutions and capacities; build more sustainable and equitable production …

Farm Bureau joins alliance of food, forest, farming and environment groups to work with Congress to reduce the food system’s role in climate change and incentivize GHG reduction

“We have established some common ground, as long as there’s something our farmers can move into and not be forced, we think we can do a better job,” said Farm Bureau president Zippy Duvall. The Farm Bureau’s board of directors approved the recommendations. “Farmers and ranchers want partnerships, not mandates, and the recommendations laid out by FACA make it clear …

Solar Panels + Agriculture: You Ain’t Seen Nothing Yet

November 19th, 2020 by Tina Casey Clean Technica It seems like only yesterday that the idea of combining solar panels with agriculture was just a twinkle in somebody’s eye. All of a sudden the field is exploding, so to speak. In the latest development, the US Department of Energy is putting down $7 million to sow the seeds for a new revolution in …

‘Nature-based solutions or nature-based seductions?’

November 2020 The hype over NbS relies on the myth that the carbon-sequestering possibilities of nature can compensate for (or in technical carbon market terms – offset) the continued burning of fossil fuels. But offsets do not reduce the overall concentration of carbon dioxide in the atmosphere; at best, they result in no net emissions. Carbon markets and offset myths are useful for …

Farmers are depleting the Ogallala Aquifer because the government pays them to do it
