Low Intensity Farming Gets High Results

Everybody knows that factory farming isn’t a sustainable use of land, but it’s still be practised because people think it’s more efficient. It turns out that low intensity farming produces some stellar results too. Researchers looking into cattle on farms found many benefits from a low intensity approach. Indeed, by practicing low intensity farming farmers cane bring life back to their soil and help benefit many species suffering through the ongoing climate crisis. Let’s be less intense, and if you’re looking for a faster fix to help farm fields recover you can reduce the amount of meat you consume.

Researchers found that less intensively managed grassland had greater diversity of plant species and, strikingly, this correlated with better soil health, such as increased nitrogen and carbon levels and increased numbers of soil invertebrates such as springtails and mites.

In the same study, the researchers used the same methods to examine the plant diversity and soil from grasslands on 56 mostly beef farms from the Pasture Fed Livestock Association (PFLA) – a farmer group that has developed standards to manage and improve soil and pasture health.

The researchers found that plots of land from PFLA farms had greater plant diversity – on average an additional six plant species, including different types of grasses and herbaceous flowering plants, compared to intensively farmed plots from the Countryside Survey. In addition, grassland plants on these farms were often taller, a quality which is proven to be beneficial to butterflies and bees.

The Future of Food is Algae

In the coming years we’ll be eating more algae if we’re lucky. Amazing algae already accounts for biofuel production and can be used to make bioplastics too, so why not keep looking for other ways to use it? At Cornell, that’s exactly what some researchers did. They discovered that coastal places are ideal places to operate onshore algae farms to grow food, ironically deserts are the some of the most efficient places to do so. With arable land being destroyed for unsustainable low density housing and meat production we need to find other ways to grow nutrients.

With wild fish stocks already heavily exploited, and with constraints on marine finfish, shellfish, and seaweed aquaculture in the coastal ocean, Greene and colleagues argue for growing algae in onshore aquaculture facilities. GIS-based models, developed by former Cornell graduate student, Celina Scott-Buechler ’18, M.S. ’21, predict yields based on annual sunlight, topography, and other environmental and logistical factors. The model results reveal that the best locations for onshore algae farming facilities lie along the coasts of the Global South, including desert environments.

“Algae can actually become the breadbasket for the Global South,” Greene said. “In that narrow strip of land, we can produce more than all the protein that the world will need.”

Save the Grocery Store, Save the Town

When markets fail people, then the people need to replace the market. Ir, to put it more directly: when a profitable grocery store isn’t profitable enough for a company then small towns need to buy that grocery store and turn it into a publicly owned asset which keeps the community alive. That’s what small towns in the USA are starting to do. By saving their local, downtown, grocery stores they keep people employed, returning to the town, and overall make life easier for everyone. The future of America might be the small box store.

The city hadn’t had a full-scale grocery store since 1985, and Giefer decided to change that. In 2008, he used city funding to get a new store, St. Paul Supermarket, off the ground. In 2013, when the couple who ran the store was staring down retirement, Giefer convinced the city to buy it outright.

In 2019, Schoenhofer drove to St. Paul to meet with that city’s clerk, who gave her some tips. The experiment, Schoenhofer found, had been a success. The St. Paul grocery employs ~15 people, and it turns a profit of 3%, slightly better than the average for rural grocery stores.

It has also kept people — and spending money — in town. Similarly, in Erie, residents show up to Erie Market for fresh lunches, like a BBQ pulled-pork sandwich or a taco on Taco Tuesday.

Plastic-Free Cucumbers Hit the Shelves in Canada

Canadians love putting food in petroleum products so much that we ship cucumbers and milk in plastic (yes, you can buy milk in plastic sacks). Thankfully, Canadians are starting to understand that plastic wrapping is wasteful and really bad for the environment. An agricultural company in Ontario has created a way to replace the plastic wrap put on cucumbers with a plant-based alternative.

These plastic-free cucumbers hit shelves the same week the federal government announced new details about its plan to ban some single-use plastics over the next 18 months, including straws, takeout containers, grocery bags and cutlery.

A 2019 Deloitte study found less than one-tenth of the plastic waste Canadians produce is recycled, equating to 3.3 million tonnes of plastic being thrown out annually, almost half of it is plastic packaging.

“Everybody wants to do their share when they’re talking about being [a] good environmental steward,” said DiLaudo.

Existing Water Filters Can Catch Microplastics

Plastic waste is everywhere and the tinier the plastic is the harder it is to deal with. These microplastics are proving to be very difficult to address which has sent researchers looking into all sort of solutions. One solution is already up and running in some places: sand filters in water systems. It turns out that some existing sand filtration systems can capture plastic nano particles.

The results are now in, and they include some reassuring findings. In a report published today in the Journal of Hazardous Materials, the researchers show that even if untreated water contained considerable quantities of nanoplastics, these particles were retained in sand filters very efficiently during water treatment. Both in laboratory tests and in a larger test facility located directly on the premises of the Zurich Water Works, the biologically active slow sand filter was the most effective at retaining nanoparticles – achieving an efficacy level in the region of 99.9%.
