Regenerative Farming Cooperative
Rural cooperative using regenerative practices to produce climate-positive food at scale.
The ask
Organise smallholder farmers in a Bangladeshi district into a cooperative that shares regenerative inputs (compost, biochar, cover-crop seed), certifies produce, and aggregates sales to urban buyers and export channels — replacing extractive mono-cropping with a diversified, carbon-building model.
Why now
Soil carbon credits are now tradable at $15–50/tonne CO₂e on voluntary markets, adding a revenue line that never existed for regenerative farmers. Input costs for synthetic fertiliser have risen 60% since 2021, making the economics of compost and green manure more attractive. Bangladesh's agri-export sector is under pressure to meet SPS and sustainability standards from EU and UK buyers who are starting to ask for verified soil-health data.
Why Bangladesh
Over 70% of Bangladeshi rural households depend partly on agriculture; landholdings average under 0.5 hectares — too small for individual certification but well-sized for aggregated cooperative certification. The Barind Tract and coastal belt are showing acute soil degradation from over-fertilisation. Rice-straw, water hyacinth, and poultry litter — abundant and currently wasted — are ideal compost feedstocks. Grameen-model cooperative structures already have legal standing and community trust in rural Bangladesh.
As a business
The cooperative earns on three rails: a small margin on certified organic or GAP-compliant produce sold to Dhaka supermarkets and export agents; shared input procurement savings (bulk compost/biochar purchasing at 20–30% discount vs. retail); and carbon credit revenue split pro-rata with member farmers. The management entity charges a 5–8% platform fee on all aggregated transactions.
Economics
Move the sliders to model your own regenerative cooperative. Defaults are order-of-magnitude estimates — pressure-testing them is part of what a founder pitches us.

What ZEPH would back
A founder with agricultural extension experience and existing farmer trust — ideally someone who has already run a pilot plot through one full cycle. ZEPH is less interested in agri-tech gadgetry and more interested in demonstrated behavior change at the cooperative level.
Impact
A 500-farmer cooperative managing 250 hectares under regenerative practices avoids an estimated 375 tonnes CO₂e per year through reduced synthetic nitrogen use (N₂O emissions) and soil carbon sequestration at ~1.5 tCO₂e/ha/yr. Replacing imported urea with on-farm compost and green manure saves roughly US$180/ha — over $45,000 per year in hard-currency fertiliser imports at baseline cooperative scale. The cooperative structure creates approximately 40 additional full-time-equivalent jobs in field coordination, logistics, and carbon monitoring, while unlocking a new income stream from voluntary carbon markets currently unavailable to individual smallholders.
