    Championing a regenerative farming revolution in Europe, with Richard Perkins, author of Regenerative Agriculture – Abundant Edge
    https://abundantedge.com/richard-perkins/

    There are a lot of inspiring voices in the regenerative agriculture community, but few have done such a thorough job of documenting and publishing every step of the development of a small profitable farm the way Richard Perkins has done with Ridgedale Permaculture. Especially now that I’ve decided to put down roots in Europe, I’ve been looking for examples of profitable small farming models for inspiration for my own project here, and between Richard’s youtube channel and two books, Making Small Farms Work and the new volume titled Regenerative Agriculture, there are few better resources to guide you step by step through all the design considerations, from landscape analysis, business planning, crunching numbers and creative paths to market.

    Though I spoke to Richard for the first time back in season 1, I invited him back for this episode to talk about some of the massive changes that are coming about from the COVID health crisis and how he’s seen it affect small farms around Europe. We explore topics like farm enterprise analysis, suggestions for direct to consumer marketing and collaboration, and Richard also talks about his observations over the years of transformation of his small farm in northern Sweden, not only from a land health perspective, but also things he’s noticed about his teaching and mentorship strategy as well as the characteristics he thinks are essential for succeeding in farming.

    TUHO: “We’re kind of like cockroaches on the planet”, one vox-pop subject tells the director, in the film’s opening seconds. “Not being judgemental or trying to play God, but we’ve got to deal with population growth”, an anti-wind farm protester declares. “Without seeing some sort of major die off in population, there’s no turning back”, anthropologist Steven Churchill adds, later on.
    Population growth is present in this film to serve this broader narrative. One graphic shows what is presumably a ‘forecast‘ shooting up to 60 or 70 billion people within a few years. Just like the exponential growth of a virus; something we know far too well this year.
    Except, the United Nations predicts population growth is slowing, and will peak at 11 billion by the end of the century. Again, misinformation serves to feed the feeling, with enough pseudoscientific information to spark emotion but nowhere near enough specificity to inform the viewer.

    Jeste k Planet of Humans:

    A new documentary released by Michael Moore, Jeff Gibbs and Ozzie Zehner, Planet of the Humans, slots neatly into pre-existing demand for content that uses misinformation to frame humanity as a virus.
    Part of reason it serves this purpose so well is that the density of falsehoods is incredible. Every re-encounter brings a new discovery. It is the gift that keeps on taking.
    Since I published my first post on this, a litany of new errors, has emerged, partly covered here. In further interviews, the filmmakers botch the basic energy math even worse than the film. One scene, where it’s alleged solar enthusiasts ‘faked’ solar power for a festival was, it turns out, seemingly filmed in 2005 (two years prior to the release of Apple’s iPhone). Another, larger event presented as being falsely powered by a nearby solar field was in 2015 (Moore says it was ‘last year‘), and that solar field was only ever marketed by organisers as powering a small nearby pavilion.
    One interviewee, Richard York, whose research suggesting renewables don’t displace fossil fuels was featured in the film, has since told media that “over the past decade, there have been more serious efforts”. The filmmakers had erased the date on the 2012 paper from the graphic on screen. Another interviewee, Richard Heinberg, revealed his interview occur.
    ...
    They filmmakers complain that the mineral and mining footprint for things like electric vehicles is non-zero. This is true of any manufactured object, so their argument is, very simply, the disavowal of any technology, of any type, scale and ownership, for any component of climate action. Community owned wind? Not allowed. Rooftop solar? It’s made from quartz, so no. Low income electricity bill reduction through locally-owned batteries? Not a chance; lithium is mined by skinny kids. Didn’t you see the montage?
    The oft-repeated gripe the filmmakers cite is “the story that climate change plus green technology equals were saved. It’s not the correct story”. But no one is telling this tale. They are shadowboxing their own imagined parody of environmentalism.
    The only explanation for this weird faux-argument is that wind and solar were prominent in the early 2010s. Electricity is the fruit that hangs lowest on the list of climate actions, and wind and solar shot ahead of competitors around 2005 – 2010.
    Everyone else moved on. A variety of tools form a major part of the plans of nearly everyone playing in this space. The International Energy Agency’s ‘Sustainable Development Scenario’ lays out one potential mix of actions to get us where we need here:

    Elizabeth Warren and Cory Booker Join Forces on Bill to Ban Most Factory Farming by 2040
    https://www.newsweek.com/...arren-cory-booker-join-forces-bill-ban-most-factory-farming-2040-1502699

    "For years, regulators looked the other way while giant multinational corporations crushed competition in the agriculture sector and seized control over key markets," Warren said in a statement. "The COVID-19 crisis will make it easier for Big Ag to get even bigger, gobble up smaller farms, and lead to fewer choices for consumers."

    "We need to attack this consolidation head-on and give workers, farmers, and consumers bargaining power in our farm and food system," added Warren. "I'm glad to partner with Senator Booker and Representative Khanna to start reversing the hyper-concentration in our farm economy."

    If passed, the law would place an immediate moratorium on new large factory farms—also known as "CAFOs," or concentrated animal feeding operations. The largest CAFOs would be entirely phased out by 2040. Medium and small-sized operations would not be prohibited, although voluntary buyouts would be offered for farmers who want to cease factory farming.

    Corporations would also be held responsible for environmental damage caused by CAFOs. In addition, law would enforce mandatory country-of-origin labelling for beef, pork and dairy products, while prohibiting the Department of Agriculture from labelling any imported meat as a "Product of USA."

    We're living through the biggest carbon crash ever recorded.
    No war, no recession, no previous pandemic has had such a dramatic impact on emissions of CO2 over the past century as Covid-19 has in a few short months.
    Multiple sources indicate we are now living through an unrivalled drop in carbon output.
    But even though we will see a massive fall this year, the concentrations of CO2 that are in the atmosphere and warming our planet won't stabilise until the world reaches net-zero.

    V posledních několika málo letech je však situace kolem sucha trošku jiná, než si pamatujeme, nebo než se můžeme dočíst ve starých tiscích. V čem? Často říkám, že je dlouhodobě (v měřítku posledních desetiletí) množství srážek v Česku zhruba stejné. Jenomže v posledních letech je „stejně podnormální“. A k tomu přistupuje problém s teplotou. Je zvýšená. Záměrně to píšu takto lékařsky, abychom si uvědomili, že bychom měli začít léčit. Pochybujete? Podívejte se na tento obrázek:

    Nejvyssi drevena stavba na svete...

    27 March 2019
    Opened on 15 March, the Mjøstårnet, or the Mjøsa Tower in Brumunddal near Oslo, Norway, is with 85.4 metres currently the world’s tallest wooden building.

    While wood was one of the first building materials used by men, its use fell out of favour because of it being known as a fire hazard. However, with the downsides of building materials like bricks, concrete and metal becoming more evident, more and more people are turning back to wood. Not the type of wood that grows on trees, though, but engineered wood that is stronger and less flammable.

    Designed by Voll Arkitekter, the 18-storey tower is made from lightweight, prefabricated materials, mainly glulam (glued laminated timber), CLT (cross-laminated timber) and MetsäWood’s Kerto LVL (laminated veneer timber), produced in Finland. Kerto LVL is lightweight, strong, and uniform and has an “outstanding strength-to-weight” ratio.

    Both the structure and the façade of the Mjøsa Tower are made of wood. The first ten floors, with offices and hotel facilities, are made of prefabricated wooden elements. The decks on the upper floors, however, where apartments are made of concrete. This is because the amount of swaying increases the higher you get in a building built of wood or concrete. The weight of the concrete makes the swaying slower and not as noticeable. The shafts for the elevators and staircases are made of CLT.

    The tower, located next to the eponymous largest lake of Norway, was built according to strict fire safety regulations. Untreated solid wood creates its own fire-resistant surface because the outermost layer chars when exposed to fire, protecting against further fire damage. Massive wooden structures manufactured in large maintain therefore their load-bearing capacity in case of fire.

    https://www.iea.org/reports/global-energy-review-2020/global-energy-and-co2-emissions-in-2020
    ...Global energy demand in the first quarter of 2020 (Q1 2020) declined by 3.8%
    ... In Q1 2020, restrictions on economic activity, as well as changes in weather, hit global coal demand hardest, pushing it down by almost 8% from Q1 2019
    ... Renewable energy demand increased by about 1.5% in Q1 2020, lifted by the additional output of new wind and solar projects that were completed over the past year. In most cases, renewables receive priority in the grid and are not asked to adjust their output to match demand, insulating them from the impacts of lower electricity demand ...
    ...Not all of the declines in demand in Q1 2020 were a result of the response to Covid‑19. The continuation of milder than average weather conditions throughout most of the Northern Hemisphere winter also pushed down demand.

    neviem ako si dosiel k tomu ze sme znizili emisie o 89%, take cislo v tom clanku nie je nikde spomenute, tam sa pise "This increase is 0.32ppm smaller than if there had been no lockdown – equivalent to 11% of the expected rise." t.j. mozno sme ich znizli na 89%? znizili sa hlavne emise z transportu, ale myslim si ze energetika aj napriek tomu, ze niektore vyroby sa nachvilu zastavili alebo zredukovali, tak vali nadalej

    lepsia by bola statistika kolko akej energie sme usetrili, t.j. ak by sme aj o 100% znizili dopravu a vsetko zastavili, tak stale to je len 1/10 z ostatnej produkcie CO2, chcelo by to vidiet aj ako klesla vyroba elektriny z uhlia, ked si pozriem (dostupne) data na electricitymap.org tak tie rozdiely v carbon intensity nie su zast tak rozdielne od doby pred covid, toto sa asi prejavi az s nejakym casovym odstupom, ked zacne krachovat fosilny priemysel a bude sa nahradzovat renewables, ale zatial si myslim, ze do uholnych elektrarni putuju vagony a vagony uhlia

    DZODZO: pomuze, ale prave nezachrani, viz moje prispevky. I pres to, ze jsme snizili emise o 89% na par mesicu a predpoklada se celorocni propad ve spotrebe ropy letos, bude dopad na konci roku na co2 zanedbatelnej.
    DZODZO

    SHEFIK: zachrani nas odchod od uhlia a ropy e.g. surovin, ktore po miliony rokov ticho cusali v zemi, tak ako to tam ostatne pisu:

    (2) the additional input of CO2 to the atmosphere (and hence to the system as a whole) by burning fossil fuels which have laid buried deep beneath the ground or ocean floor for millions of years
    SHEFIK
    SHEFIK --- ---
    SHEFIK: vice mene se nepletu, z clanku:

    In other words, without the lockdown, the total amount of CO2 in the atmosphere would have increased by 0.68% in 2020, compared to the 2019 global average. But with the lockdown, we project the increase to be 0.60%.

    If global emissions reduce by 8% over the year, with the largest reduction in April, the annual minimum monthly CO2 by September will be 410.6ppm (±0.6), compared to 411.1ppm (±0.6) expected without the Covid-19 impact.

    jinymi slovy, dopad covidu je minimalni (max 8% novyho prirustku) a uskromnit se nam v budoucnu vubec nepomuze, muzeme zacit klidne zas vesele litat. zachrani nas jen CCS nebo natural sinks, temata, o kterych mluvi TADEAS apod.

    TUHO: me to prijde naky divny, z matematickyho pohledu, nekde musi bejt chyba (mozna u me). kdyz clanek pise, ze jsme na 11% produkce co2, jakotoze:

    1) rosteme podle krivky temer stejnym tempem, kdyz bychom meli rust o 89% mene (covid 19 emissions redcution)?
    2) observed seasonal cycle je vcetne lidskyho impactu, beru to jako sumu co2, jenze
    a) jaro zaclo velmi brzo letos, (alespon v cr) vegetace uz temer v plny mire odcerpavaj co2 ze vzduchu, pricemz krivka vede v kvetnu stale nahoru
    b) z uvedeneho vyplyva, ze pokud jsem lidske emise redukoval o 89%, tak ten impact na krivku je minimalni, tedy vetsina co2 ma pricinu jinde nez antropogennim vlivem (dle tohoto grafu a dat)
    3) kdyz si vezmu podle grafu, ze za posledni rocni cyklus (od hvezd jsem nabral 3ppm) a mel bych do dalsi hvezdy rust o 89% min, mel bych narust od boku o max 0,5ppm, jenze na grafu jsem dle odhadu zase temer o 3ppm navic (modra hvezda)

    tenhle graf je imho z kratkodobyho (par let) hlediska uplne bez vypovidajici hodnoty, a to i presto, ze si to sama klade za cil, kdyz se snazi modelovat impact covidu... vychazi z dlouhodobejch dat a tim padem zkresluje kratkodobej impact

    Američané mnohem méně jezdí auty a utlumení průmyslu i těžby způsobilo mnohem menší emise skleníkových plynů. Od doby, kdy v březnu začala platit opatření proti nemoci covid-19, se USA podle nové zprávy Road Ecology Center Kalifornské univerzity v Davisu začaly blížit splnění klimatických cílů pařížské dohody.

    But a key question for climate change is what impact this has had on the overall amount of CO2 in the atmosphere – the principal driver of global temperature rise. In our analysis for Carbon Brief, we assess whether the global drop in emissions will have a noticeable impact on atmospheric CO2 concentrations this year.
