The federal government’s plan to cut fertilizer emissions will not threaten food security

The emission reduction targets outlined for Canadian fertilizer use will not lead to food shortages and food insecurity.

Rise of precision agriculture exposes food system to new threats

Bringing advanced technologies to the ancient practice of farming could help feed the world’s growing population, but it could also open the door for people looking to disrupt the global food system.
The key to unlocking the benefits of new agricultural technologies is to develop food systems where the waste products from one step become valuable inputs in another. (Shutterstock)

5 technologies that will help make the food system carbon neutral

The world is facing one of the century’s biggest challenges: How to nutritiously feed the growing population, address climate change and not destroy the ecosystems on which we all depend for life.

Water being pumped into Tampa Bay could cause a massive algae bloom, putting fragile manatee and fish habitats at risk

Harmful algae blooms are an increasing problem in Florida. Once nutrients are in the water to fuel them, little can be done to stop the growth, and the results can be devastating for marine life.

New research: nitrous oxide emissions 300 times more powerful than CO₂ are jeopardising Earth’s future

Agriculture is the dominant cause for the increasing N₂O concentrations. Emissions must be reduced if we hope to stabilise Earth’s climate.

Microwaving sewage waste may make it safe to use as fertilizer on crops

The solids from wastewater plants are usually dumped into landfills because they are contaminated with heavy metals. Now there is a way to remove the metals so the waste can be used as fertilizer.

Great Lakes waters at risk from buried contaminants and new threats

The Great Lakes contain reservoirs of legacy contaminants, mostly in their sediments, that are vulnerable to resuspension.

Regenerative agriculture can make farmers stewards of the land again

US agriculture is dominated by large farms that rely on chemical inputs. In contrast, regenerative farming makes land and water healthier by mimicking nature instead of trying to control it.
‘Silent Spring’ author Rachel Carson testifies before a Senate Government Operations Subcommittee in Washington, D.C. on June 4, 1963. Carson urged Congress to curb the sale of chemical pesticides and aerial spraying. AP

Would Rachel Carson eat organic?

Did Rachel Carson catalyze the organic farming movement, as many advocates claim? Or would she reject their ban on synthetic fertilizer and see organic as an inefficient way to feed the world?
