Why organic farming matters for East Africa

Across East Africa, the conversation about how food gets grown has shifted. Rising input costs, unpredictable rainfall, and tired soils have pushed farmers and buyers alike to ask whether the conventional model of synthetic fertilisers and chemical sprays can keep working for the long term. For TanzPro Greens Ltd, based in Dar es Salaam, the answer arrived years before the question became fashionable.

Founded in 2014, TanzPro has spent more than a decade working the coastal soils of Mkuranga District, Tanzania, building an approach to agriculture that treats organic methods not as a niche market position but as the only viable way to farm. That conviction was shaped on the ground, through two sister projects that trace the company's growth.

The Mitaranda Organic Project began in 2016 with just six women farmers working greenhouses and open fields. Two years later, the Kisele Organic Project started along Mtwara Road, eventually expanding to three greenhouses. It was at Kisele that much of TanzPro's organic vision was tested and refined, one plot at a time.

The proof of that work shows up in what the fields actually produce. Tomatoes, cherry tomatoes, peppers and chillies, cucumbers, cabbage, carrots, onions, and beans grow alongside avocado, pineapple, and passion fruit, with ginger, garlic, herbs and spices, moringa powder, roselle powder, organic honey, and sunflower oil rounding out what leaves Mkuranga. Growing that range of crops organically, season after season, without exhausting the land, is only possible because the soil itself is being rebuilt rather than mined.

The methods themselves are old ones, rediscovered rather than invented. Crop rotation keeps pests and disease from settling into a single field year after year. Green manure - cover crops turned back into the soil - replaces nutrients that would otherwise come from a bag of imported fertiliser. Composting closes the loop, returning farm waste to the ground as usable nutrition instead of waste.

Pest control follows the same logic. Rather than reaching for synthetic chemicals, TanzPro relies on bio-pesticides and biological methods, alongside a strict commitment to GMO-free seed. Every step is designed to work with the soil's own biology instead of overriding it.

Sustainability at TanzPro does not stop at the field edge. Packaging for export produce is compostable, extending the same no-waste philosophy that governs composting and green manure on the farm into how the produce is finally shipped out to buyers. It is one more point in the chain where the easy, cheaper option was set aside in favour of the one that matches the farm's own standards.

None of this is only about the produce that leaves the farm. Healthy soil holds water better, resists erosion, and recovers faster from the dry spells and irregular rains that are becoming more common across the region. Organic farming, in that sense, is as much a climate strategy as a food-safety one - the foundation everything else is built on.

Irrigation is managed through a mix of drip systems and rain-fed fields, matched to what each plot can support without depleting groundwater. It is a deliberately unglamorous kind of farming, focused on balance rather than maximum extraction.

TanzPro's environmental commitment extends past the growing season. For every tonne of produce exported, the company plants 50 indigenous trees, tying the business's growth directly to reforestation rather than treating the two as separate concerns.

That same discipline shows up once an order is confirmed. Produce is hand-harvested, sorted, and graded within hours, then pre-cooled at the packhouse before being packed into food-grade cartons for dispatch through Julius Nyerere International Airport in Dar es Salaam. A sunrise harvest can reach buyers in the Seychelles or the Gulf within 24 to 48 hours, proof that organic methods do not have to mean slower or less consistent supply than conventional farming.

By 2019, this groundwork had translated into TanzPro's first commercial harvest at scale, supplying restaurants, hotels, and retailers in Dar es Salaam. It was an early signal that organic farming, done properly, could meet the volume and consistency that commercial buyers demand - not just the standards that certification bodies require.

This way of working is recognised through the East African Organic Mark (Kilimohai), and TanzPro is a member of the Tanzania Organic Agriculture Movement (TOAM). The company also follows Fair Trade principles in how it works with the farmers who supply it, an approach that matters as much as any certification.

Those affiliations are not decorative. The Kilimohai mark and TOAM membership both point to verifiable organic practice rather than a label added at the last minute, and TanzPro's produce remains entirely GMO-free from seed to harvest. For a buyer evaluating a new supplier from thousands of kilometres away, that kind of independently recognised standard does much of the reassurance that an in-person inspection would otherwise have to provide.

That farmer network has grown well beyond its six-woman beginning. TanzPro now works with more than 50 contracted farmers, around 70 percent of them women from rural communities around Mkuranga. Each is trained in organic cultivation, supplied with certified seeds, and guaranteed a market for what they grow - removing much of the risk that has historically kept smallholders out of export-quality agriculture.

That network now supplies five markets - the Seychelles, the UAE and Oman in the Gulf, Russia, and East Africa's own local demand - each expecting the same organic standard regardless of distance. Meeting that expectation consistently, across both nearby and long-haul buyers, is the clearest evidence that it is the underlying farming method, and not just a single good harvest, that is being sold.

The result is a business producing more than 200 tons of organic produce a year, feeding local markets and five export destinations. It is proof, in TanzPro's view, that organic farming in East Africa is not a constraint on growth but the condition for it.

TanzPro Greens Ltd works with buyers, partners, and smallholder farmers who want to be part of this approach to agriculture. To discuss sourcing, supply, or partnership opportunities, reach the team by phone at +255 713 398 485 or by email at om@tanzpro.co.tz.
