    CSIRO debunks cattle myths | Farm Weekly | Western Australia
    https://www.farmweekly.com.au/story/7542239/csiro-debunks-cattle-myths/?cs=5151

    The typical Australian grain-fed beef production system contributes almost twice the human-edible protein its cattle consume, while grass-fed systems contribute almost 1600 times.

    Ruminants are a superb use of land, and grain, in terms of contributing valuable protein to feed the world.

    That provides an added dimension to discussions around beef's environmental footprint.

    ...

    The CSIRO team plugged the concept into a model of typical Australian beef supply production, where animals grow on grass for the majority of the time.

    They modelled data including methane emissions, historical climate records and commercial feedlot diets.

    The study, published in the journal Animal, is the first time the concept has been applied in Australia.

    It rated Australian grain-fed beef a score of 1.96 and grass-fed with a very small amount of grain a score of 1597, where a number greater than one means it has a positive contribution to meeting human nutritional requirements.

    "If you talk to people who are rejecting red meat on environmental grounds, what they say is beef is resource-intensive," Dr Lehnert said.

    "This is perhaps because if you look at tonnes of feed cattle consume in isolation - those numbers seem very large.

    "By applying this concept of putting protein for humans at the end and calculating back what is put into a system, we've come up with this finding that we believe will surprise people.

    "The work offers a different perspective on the decisions weighing up protein choices in our diets against environmental indicators."

    CSIRO scientists also studied how much methane is produced in the two production systems. On average, grain-finished beef generated 30 per cent less methane per unit of beef than the grass-fed system. This difference is largely because animals grow more slowly when fed solely on grass, so they're on the planet longer.

    The bottom line, according to CSIRO, is that the picture is complex when taking sustainability into account in food choices

    Global Fertilizer Shortage Sends Demand for Manure Soaring
    https://news.yahoo.com/global-fertilizer-shortage-sends-demand-160001632.html

    Prices of synthetic fertilizer, which rely on natural gas and coal as raw materials, have soared amid an energy shortage and export restrictions by Russia and China. That’s adding to challenges for agricultural supply chains at a time when global food costs are near a record high and farmers scramble for fertilizers to prevent losses to global crop yields for staples.

    The Green Markets North American Fertilizer Price Index is hovering around an all-time high at $1,072.87 per short ton, while in China, spot urea has soared more than 200% this year to a record.

    The demand for dung is playing out globally. In Iowa, manure is selling for between $40 to $70 per short ton, up about $10 from a year ago and the highest levels since 2012, according to Daniel Anderson, assistant professor at Iowa State University and a specialist on manure.

    Manure is mostly a local market and truckloads won’t go further than 50 miles (80 kilometers), Anderson said. When crop, fertilizer and manure prices soared about a decade ago, more farmers reintroduced animals such as hogs and cattle onto their land, in part for their manure. That option could again be on farmers’ minds as fertilizer costs soar.

    In Australia’s Queensland state, Brian Mclean, general manager of an organic fertilizer company, said that sales of his poultry manure compost are going through the roof. If interest keeps up at the same rate, people seeking ready-treated manure in the area would soon miss out.

    “There wouldn’t be enough in total,” he said. In just the last few months he’s sold about 15,000 tons of the stuff, compared to around 2,000 tons the same time last year, though some of the renewed fervor has been driven by a bounce-back in weather conditions after years of drought, Mclean added.

    In the U.K., not only are farmers scrambling for animal compost, but many are even trying to get their hands on treated sewage sludge containing human excrement, or biosolids. David Butler, who farms wheat, oats and peas in Wiltshire in the southwest of England, has traditionally relied on his own herd of cows to produce animal waste that he uses for his crops.

    Front Matter | A Research Strategy for Ocean-based Carbon Dioxide Removal and Sequestration | The National Academies Press
    https://www.nap.edu/read/26278/chapter/1#ii


    Is ‘hacking’ the ocean a climate change solution? U.S. experts endorse research on carbon-removal strategies.
    https://www.washingtonpost.com/climate-solutions/2021/12/08/climate-change-ocean-carbon-storage/

    the 300-page report from one of the country’s top research organizations argues that the United States should at least investigate whether ocean-based carbon-removal strategies are worthwhile.

    The new report — released Wednesday and sponsored by ClimateWorks, a San Francisco-based nonprofit group — is adamant that carbon-dioxide removal is not a substitute for immediately eliminating fossil fuel use and curbing greenhouse gas pollution. It does not endorse any of the six strategies it considers or even advocate for CDR to be deployed.

    Instead, it outlines a 10-year, $1.1 billion research program that would fill in crucial knowledge gaps about each technology.

    Some of the questions are purely scientific, Doney said: “Does it actually work? Does it store carbon for sufficiently long periods of time? What are the environmental impacts?”

    Many more questions are legal, economic or ethical: “How would you govern this? What are the dimensions of social acceptability?” Doney said. “If you could slow climate change or stabilize climate at a lower warming level, is that worth the trade-offs of these deliberate changes to the ocean? … These are things society needs to decide.”

    The report also recommends the development of a research code of conduct for ocean-based CDR, with stipulations that the experiments be tightly regulated and involve experts from Indigenous groups and other vulnerable communities. The scientists say the $125 million foundational research agenda must include surveys, legal analyses and in-depth interviews with the people whose lives and livelihoods will be affected by the projects.

    Experiments should be “co-produced with communities,” said Holly Buck, a sociologist at the University at Buffalo and a contributor to the report. Including locals in the design and deployment of projects will make them more equitable and could reveal insights scientists had never considered.

    And researchers must be willing to change course, Doney said, if their work turns out to be ineffective or dangerous, or if more powerful methods come to light.

    “This is the kind of deep dive we need,” said Kim Cobb, a climate scientist and oceanographer at the Georgia Institute of Technology who was not involved in the National Academies study. “It helps us to understand the potential benefits and downside risks and all the warts that you don’t get in the battles that are waged on op-ed pages.”l

    2021 Can large herbivores enhance ecosystem carbon persistence?
    https://www.cell.com/trends/ecology-evolution/fulltext/S0169-5347(21)00257-3

    “Herbivores can increase the persistence of ecosystem carbon through redistributing carbon from aboveground vegetation pools vulnerable to disturbances into persistent soil pools.”

    “This is particularly important in ancient fire-prone grasslands, but increasing disturbance frequencies across many ecosystems make herbivore restructuring of carbon pools relevant in a wider range of systems.”
