The “4 per 1000” initiative, launched at COP21, proposes raising carbon in the top 40 cm of soil by 0.4% each year. Until now, countries in the region relied on IPCC default values calculated for the whole world. The platform sets out to answer four questions:

• How much carbon can each soil store, given its climate?

• How close are current production systems to that level?

• Which practices help close the gap?

• What economic benefit do farmers gain by applying them?
