If we want to reduce carbon emissions and preserve planetary ecosystems, we need to protect our soils.
Realities on the ground tell a different story from the claim that a Green Revolution ensures food security and increased income for smallholder farmers in Ghana.
Guano helped humans farm the world’s driest desert, new research finds.
If rolled out worldwide, our method could replace a quarter of all the synthetic nitrogen fertiliser used in agriculture.
What do ammonium nitrate and iodine have in common? Both substances are of immense service to humankind, and the history of their discovery is closely linked to that of the production of explosives.
Agriculture is the dominant cause for the increasing N₂O concentrations. Emissions must be reduced if we hope to stabilise Earth’s climate.
It’s painfully clear nature is buckling under the weight of farming’s demands. There’s another way – but it involves accepting nature’s limits.
And why development funders should listen to smallholder farmers
We need phosphorus for life, as well as for fertiliser to help plants grow, but raw supplies are limited.
Wildflowers, bees and butterflies – your lawn is a vibrant ecosystem waiting to be unleashed.
Feeding pigs seaweed could make them, us and the planet healthier without contributing to antibiotic resistance in bacteria.
Existing toilets aren’t a good fit for parts of sub-Saharan Africa because many areas lack water and there’s often no proper plumbing.
An ancient relationship between plants and fungi could be used in sustainable agriculture. But there’s still a lot we don’t know, and new research suggests these fungi can sometimes do more harm than good.
Producing ammonia, which is a key ingredient in fertilizers, is one of the world’s most energy-intensive chemical manufacturing processes. Now there’s a new low energy option in development.
The federal government’s new $500 million funding package for the Great Barrier Reef seems predominantly focused on the tactics that are already being tried, without much success.
Plenty of cafes these days will let you take home some used coffee grounds, to put on your garden. It’s a versatile material with loads of potential uses - as long as you treat it properly first.
There were some African food security initiatives from 2017 that deserve a special mention for the precedent they set.
The updated plan for improving water quality on the Great Barrier Reef still doesn’t address the need to curb intensively farmed crops such as sugar cane, and to enforce existing environmental laws.
It is essential to maintain global food supply, but the clock is ticking.
