When Janet Maro started building training programs with farmers in Tanzania, she didn’t arrive with a curriculum. She asked farmers what they knew, what they needed, and what they could bring to the table — and built from there. That instinct, to treat farmers as the architects rather than the audience, turns out to explain most of what makes Sustainable Agriculture Tanzania unusual: why groups keep meeting and planning years after projects end, why an organic shop opened in Morogoro in 2012 has since seeded eight more across the country, and why a conflict between Maasai pastoralists and smallholder farmers that had turned violent was resolved not through outside intervention but through a simple exchange of manure and crop residues, negotiated by the communities themselves.
