https://fb.me/e/HTsxqF1M


Asi málokdo by o sobě řekl, že je mu příroda ukradená. Přesto jako společnost zůstáváme v zajetých kolejích a pokračujeme v chování, které si na životním prostředí vybírá daň.

- Proč je pro nás změna tak těžká?
- Co nám stojí v cestě za udržitelným chováním?

Odpovědi na tyto otázky z perspektivy sociální psychologie a behaviorálních věd nabídnou Ondřej Kácha s Lindou Soukupovou z Green Dock, z.s.

Přednáška bude probíhat online v úterý 15.6. Začínáme v 18:00. Těšíme se na vás!

Solar makes a lot of sense at ground level, too – pv magazine International

Solar projects that support native grasses can sequester more carbon than farmland alone.
...
From an emissions-capturing standpoint, these native grassland habitats are important because they sequester almost 60% more carbon per acre than modern agricultural activities.

The study modeled and averaged solar facilities in seven states in the Upper Midwest. Their modeling suggests that native grasses planted as part of 10 GW of solar generation capacity would sequester 129.3 tons of carbon per hectare; that is 65% and 35% greater than either an agriculture or a solar-turfgrass scenario, respectively.

The researchers said that this volume of emission sequestration is equivalent to the emission savings of 5,000 GWh of fossil generation shifting to solar power, which would correspond to greater than 3 GW of solar capacity.

The paper found that in addition to carbon sequestration, native grassland habitats also produce a three-fold increase in habitat for local pollinators, like bees and butterflies, when compared to pure agricultural usage. The threat of erosion from poor management still looms for midwestern soil. Solar and native grasslands would protect this fertile asset from losses of up to 9,000 tons of sediment erosion annually, and would retain more than 40,000,000 cubic meters of water from runoff annually.

Prior observational research has shown that solar panels create microclimates in semi-arid regions by significantly increasing the water retention in soil, which in turn increases sheep and cow grazing grasses by 90%.

A few common bacteria dominate soil's carbon cycle - UPI.com

Previously, scientists were only able to make general assumptions about how communities of soil bacteria were behaving -- the equivalent, according to Hofmockel, of reporting that a state went red or blue in an election.

"Now, with qSIP, we can see who is driving that larger pattern -- the 'election results,' if you will -- at the level of individual microbial neighborhoods, city blocks," Hofmockel said. "In this way, we can start to identify which soil organisms are performing important functions, like carbon sequestration, and study those more closely."

...

Better understanding how individual organisms contribute to carbon cycling has important implications for managing soil fertility and reducing uncertainty in climate change projections

...

The planet's soil hosts twice as much carbon as its vegetation. As such, understanding the soil carbon cycle is key to modeling the planet's broader carbon cycle and predicting how it will be affected by climate change.

Opinion | Six Months to Prevent a Hostile Takeover of Food Systems, and 25 Years to Transform Them | Nick Jacobs
https://www.commondreams.org/views/2021/04/07/six-months-prevent-hostile-takeover-food-systems-and-25-years-transform-them

the "4th industrial revolution" is already sweeping through food systems. For proof, we need look no further than the changing complexion of the agri-food sector, where mergers and market disruptions are occurring at a dizzying pace. E-commerce platforms like Amazon and China's JD.com are now among the top ten retailers globally. With agribusinessesincreasingly reliant on cloud, AI, and data processing services, big tech firms like Amazon, Alibaba, Microsoft, Google, and Baidu are moving into food production. Meanwhile, Blackrock and 4 other asset management companies own 10–30% of the shares of the top agri-food firms.

With climate change, environmental breakdown, and pandemics wreaking havoc on food systems over the coming years, the "silver bullet" solutions offered by the new agri-food giants may prove irresistible to panicking policymakers. This year's UN Food Systems Summit—arising from a partnership between the UN and the World Economic Forum—will be a showcase for corporate-led "solutions."

In other words, the keys of the food system are already being handed over to data platforms, e-commerce giants, and private equity firms. This could mean dismantling the diversified food webs that sustain 70% of the world's population and provide environmental resilience. It could mean putting the food security of billions of people at the mercy of high-risk AI-controlled farming systems and opaque supply corridors.

And yet, there is nothing inevitable about this dystopian future. In reality, divisions will grow among corporations and between companies, workers, and consumers, as ecosystems refuse to be tamed, people refuse to be nudged, technologies malfunction, and environmental and social tipping points draw closer.

Farmers, food workers and their allies have recognized the crossroads we are at. They are already organizing in new ways to defend their spaces, their livelihoods, and their future—starting with mobilization around the Food Systems Summit.

In scanning the landscape for clues about the next quarter century, we found that what could be achieved by civil society and social movements is just as "disruptive" as the plans of the agri-food giants. A "Long Food Movement"—bringing together farmers, fishers, cooperatives, unions, grassroots organizations and international NGOs—could shift $4 trillion from the industrial chain to food sovereignty and agroecology, cut 75% of food systems' GHG emissions, and deliver incalculable benefits to the lives and livelihoods of billions of people over the next 25 years

World-first discovery could fuel the new green ammonia economy
https://phys.org/news/2021-06-world-first-discovery-fuel-green-ammonia.amp

The production of each metric ton of ammonia contributes to the emission of roughly 1.9 metric tons of carbon dioxide, and accounts for roughly 1.8 percent of global carbon emissions.

A team of Monash University scientists, led by Professor Doug MacFarlane, Dr. Bryan Suryanto and Dr. Alexandr Simonov, have discovered a process based on phosphonium salts that represents a breakthrough in overcoming this carbon-intensive problem.

The research, published in the prestigious journal Science, unlocks the potential to produce ammonia and fertilizers from renewable energy in reactors, as small as a refrigerator, that could be rolled out at the individual farm or community level.

Direct, zero-carbon ammonia synthesis methods currently being explored include the electrochemical nitrogen reduction reaction, which can produce ammonia at room temperature and pressures from nothing more than air, water and renewable energy.

...

Professor MacFarlane, an internationally renowned chemist, believes the use of carbon-neutral production technologies could also see ammonia used as a fuel and replace fossil fuels by 2050.

Ammonia is already widely considered to be the ideal zero-carbon fuel for international shipping in the future, a market predicted to be worth more than USD$ 150 billion by 2025.

"The technology that we have developed also opens up a broad range of possibilities for future scale up to very large production facilities for export, attached to dedicated solar and wind farms," Professor MacFarlane said.

Brazil’s Amazon deforestation surges 67% in May as Bolsonaro pledges fall flat | Reuters
https://www.reuters.com/business/environment/brazils-amazon-deforestation-surges-67-may-bolsonaro-pledges-fall-flat-2021-06-11/

Deforestation in Brazil’s Amazon rainforest rose for a third consecutive month in May, preliminary government data showed on Friday, with President Jair Bolsonaro yet to follow through on his April pledge to boost funding for environmental enforcement.

Deforestation soared 67% in May from the same month last year, according to Brazil's national space research institute Inpe, with much of the land targeted for cattle ranches, farms and logging.

For the first five months of the year, the data show deforestation was up 25% compared with a year earlier, with 2,548 square km destroyed - an area more than three times the size of New York City.

Deforestation peaks during the dry season from May to October, when it is easier for illegal loggers to access the forest.

Bolsonaro pledged at an Earth Day summit in April to double funding for environmental enforcement. The next day, he signed the 2021 federal budget that slashed environmental spending.

Mikroskopický mnohobuněčný organismus nalezený na Sibiři se probral k životu po 24 tisících letech, které strávil zmražený v tamní řece. Popsali to vědci v nové studii zveřejněné v odborném časopise Current Biology. Odborníci si dosud mysleli, že podobné organismy dokáží v zamrzlém stavu strávit kolem deseti let, nyní se však domnívají, že je jejich schopnost přežít v podstatě neomezená.
