Japanese high-rises are more than just offices and shops – some have mini-farms too, even as the number of rural agriculture workers falls

Across Japan, city dwellers have been developing quite the green thumb. Urban “citizen farms”, as they are called, grew in size by 36 per cent over 10 years, from totalling 641ha in 2005 to 877ha in 2015, according to the Ministry of Agriculture, Forestry and Fisheries (MAFF).

While much of this land has traditionally been greenhouses or fields located in city suburbs, there has been a push towards integrating the old-school farming concept into the urban landscape – both for commercial and community engagement purposes – by companies across industries from real estate to transport.

German startup leads the way in urban farming

The start-up currently has more than 50 farms running around Berlin in supermarkets, restaurants, and warehouses. The startup has already placed its farm in German supermarket chains METRO and EDEKA, two of Germany’s largest food retailers.

Infarm builds in-store farming units and software to manage the growth of crops. The farms are operated by Infarm’s own platform for monitoring thousands of different data points and personalizing the farm to respective needs, which ensures that the produce is being grown as near to perfect as possible. Each module has its own ecosystem that tailors light spectrum, temperature, pH levels, and nutrients to ensure the maximum expression of each plant.

Canada: Verifying Safety of Compost Used for Vegetable Production

Figure 2. E. coli and fecal coliform measurements in market ready composts in British Columbia after rewetting and incubation for 24-48 hours.

The future of our organic vegetable industry, as well as the future of our organics recycling industry relies on us all participating to ensure the safety of our produce.

What can we do to provide assurance that potential pathogens from compost do not enter the food chain? There is evidence identifying the risk of potential pathogen regrowth, including E. coli, particularly with immature compost. Researchers have identified potential human pathogenic organisms that can enter a VNBC (Viable but not Culturable) state, including antibiotic resistant E. coli, which allows them to survive the high temperatures required for the composting process.

In a review of the OMRI Listed (OMRI Canada) residential food waste and yard waste compost produced by the City of Whitehorse, we conducted further testing to ensure that potential pathogens would not regrow. Compost samples were taken from various stages in the aerated windrow composting process, stored at 5-15 C for 48 hours, then sent to the laboratory to measure fecal coliform and maturity. We found that compost that met the CCME maturity requirement (< 4 mg CO2-C/g OM/day) still had risk of fecal coliform regrowth, and there was no regrowth in compost having a respiration rate below 1.5 CO2-C/g OM/day). The OMRI approved compost marketed by the City of Whitehorse was determined to be safe with no potential for potential pathogen regrowth.
