A test case in Franschhoek, South Africa has used natural filtering of polluted water to produce 50,000 litres a day that is safe for irrigation.

There are ways to reduce emissions without sacrificing yield. A new study shows how, and looks at a technique billed as ‘climate-friendly’ that makes emissions worse.
An environmental engineer explains how his research team is developing a system containing bacteria, biochar and gel to break down pollutants in waterways.
Adding biochar to degraded soils boosts how much water soils can hold and help farmers survive droughts.
Agricultural sustainability is as much about power and sovereignty as it is about soil, water and crops.
Zero emission? Carbon neutral? Carbon negative? What does it mean to achieve ‘net-zero’ emissions?
Energy Minister Angus Taylor is this week expected to release the government’s first Low Emissions Technology Statement. It’s likely to include ways to remove CO₂ from the air – but do they work?
A federal government plan to increase soil carbon stores is a folly that misunderstands the technology.
Unused biomass residues from maize, sorghum, rice, millet and groundnut in Uganda show to offer unique opportunities for circular production and soil amendment of biochar.
Evelyn Krull, a research scientist at the CSIRO, asked in these pages whether biochar could save the planet. Eighteen months have passed and although research efforts continue, still no meaningful quantities…
