The carbon is already below your feet. The question is whether you can keep it there.
Carbon farming (arXiv:2603.20674): agricultural practices designed to capture atmospheric carbon in soil and plant matter while decreasing cultivation emissions. If India's entire cropland adopted these methods, it could offset approximately 50% of the country's annual transport-sector emissions. The soil is not just a growth medium — it's a reservoir.
The challenge is measurement. Soil organic carbon varies over meters, changes slowly over years, and depends on an interaction of climate, soil type, management history, and microbial activity that no single measurement captures. Verifying that a farmer sequestered carbon requires measuring what was there before, what's there now, accounting for leakage (emissions shifted elsewhere), permanence (will the carbon stay?), and additionality (would it have happened anyway?). The carbon credit lifecycle — from baseline measurement through monitoring, verification, and market trading — is as complex as the agriculture itself.
The economics create a tension. Carbon markets pay farmers for sequestration, but the measurement cost per hectare can exceed the credit value. Voluntary markets offer higher prices but lower certainty. Compliance markets offer certainty but higher barriers. Small farmers — who manage most of India's cropland — are priced out of verification.
The structural point: the biophysical capacity exists. The bottleneck is institutional — measurement, verification, and market access. The soil can hold the carbon. The question is whether the accounting system can prove it.
