DODOMA — As Tanzania celebrates the 10th anniversary of the Tanzania Agricultural Research Institute (TARI), the nation has set its sights unambiguously on an agricultural revolution that will reshape the sector by 2050. At the Nane-Nane celebration in Dodoma this week, Vice President Emmanuel Nchimbi emphasised a singular truth that will define the next quarter-century: research is not a luxury—it is the foundation upon which all agricultural progress rests.
From Three Billion to 124 Billion: A Decade of Exponential Commitment
When TARI was formally established in 2016, carved from the agricultural research directorate of Tanzania’s Ministry of Agriculture, the initial budget allocation was approximately three billion Tanzanian shillings. Today, that commitment has surged to 124 billion shillings. This 40-fold increase is not merely a financial milestone; it is a statement of national intent.
Dr. Thomas Bwana, Director General of TARI (appointed by President Samia Suluhu Hassan in February 2024), explained the scale of government investment. “Tangu mwaka 2018 hadi leo tumetoka bajeti ya shilingi bilioni takriban tatu hadi kufikia takriban bilioni 124. Hii inaonyesha kwamba serikali iko serious katika kuhakikisha kwamba sio mazingira tu ila inatoa pia uwezesho wa utafiti kufanyika,” he stated.
Vice President Emmanuel Nchimbi, in his keynote address, pointed to the groundbreaking ceremony for TARI’s new governance building, conducted by the Prime Minister this week, as concrete evidence of this commitment. The establishment of two specially designated research centres—one in Dodoma focusing on climate change and crop science, and another in Tabora dedicated to agroforestry and medicinal crops—further underscores the strategic expansion of TARI’s infrastructure.
A Portfolio of 343 Technologies: Translating Science into Prosperity
Over its first decade, TARI has generated or refined 343 technologies, with the majority being improved seed varieties distributed to farming communities across Tanzania. The institute’s reach now spans all major crops—from maize and rice to pulses, vegetables and fruits—and encompasses the entire agricultural value chain, from production through to post-harvest processing.
The evidence of impact is tangible. Tanzania’s food security ranking has risen to 130 out of 184 countries globally. More locally, farmers across the nation now cultivate varieties that trace their lineage directly to TARI’s laboratories. A cashew variety produced in Dar es Salaam; a red grape developed in Dodoma; medicinal beans enriched with iron and zinc now served in school feeding programmes across East Africa.
Yet what TARI has created in the laboratory is only half the story.
The Second Half of the Problem: Processing, Value Addition, and the Lost Billions
Professor Nuhu Hatibu, TARI’s Director General, delivered a sobering economic reality to the assembled government officials, researchers, and agricultural stakeholders. Tanzania grows raw commodities—maize, cashews, cotton, rice—only to see their value captured elsewhere in the global chain.
He illustrated the problem with precision: a smallholder farmer selling raw maize receives approximately 0.25 shillings per kilogram. If that maize is processed into standard starch for laundry use, the farmer’s share might climb to 0.50 shillings—a doubling, but still marginal. Yet when that same maize is transformed into the pharmaceutical-grade starch used to bind medicine tablets—where maize comprises 98 per cent of the capsule itself—the farmer’s potential return jumps to 40 shillings per kilogram.
“Faida itakayorudi kwa mkulima inakwenda juu mara 40 kwa kilogram,” Professor Hatibu stated bluntly, driving home the chasm between raw-commodity farming and value-added processing.
This is not an anomaly. It reflects a systemic failure: whilst manufacturing enterprises investing in processing capacity have surged ahead of agricultural innovation, Tanzania’s research apparatus has focused relentlessly on production, leaving a cavernous gap in industrial-scale food processing research.
“Tumetumia nguvu nyingi sana kwenye upande wa kuleta vitendea kazi na pembejeo na technology kwa ajili ya uzalishaji. Lakini tumekuwa na upungufu mkubwa sana kwenye utafiti na teknolojia za kisasa za kusindika mazao yetu na kuongeza faida,” Professor Hatibu told the gathering, articulating a research priority that has been systematically neglected.
The 2050 Vision: Ten Targets That Demand a Research Revolution
With clarity, the Government has articulated five strategic objectives to guide agricultural growth through 2050:
Annual Growth: Increase agricultural sector growth to 10 per cent annually (current rate: 4–5 per cent).
GDP Target: Reach 100 billion dollars in agricultural GDP by 2050.
Exports: Achieve a net agricultural export value of 20 billion dollars by 2050.
Mechanisation: Achieve 100 per cent mechanisation across all farming and primary processing operations.
Irrigation Expansion: Increase irrigated farming from current levels to 1.2 million hectares, with particular focus on crop water requirement modelling and drought-tolerant phenotypes.
Post-Harvest Loss: Reduce post-harvest losses from the current catastrophic level of 30–40 per cent down to just five per cent through cost-effective storage technologies tailored to specific crops and improved cold chain solutions.
Each target is scientifically achievable. Yet none can be reached without fundamental research breakthroughs in precision agriculture, agroecology-by-agroecology farming models, value-added product development, and digital soil mapping.
The Precision Agriculture Imperative: From Blanket Approaches to Granular Intelligence
One of the most compelling insights to emerge from the research agenda is the need for “precision agriculture” at a scale Tanzania has yet to attempt. Scientists in China and Japan have already moved beyond conventional approaches: Japanese magnetic levitation trains hint at an innovation mindset; Chinese vacuum tube trains point toward transport futures.
In agriculture, the equivalent precision is this: current mechanisation spreads fertiliser uniformly across a field. A tractor deposits the same quantity of nitrogen into metre-by-metre sections, regardless of soil composition. Future farming must differentiate: soil pH varies across a single plot; nutrient availability differs between adjacent areas. A precision tractor should “know” that this square metre requires double the phosphate whilst that one needs half.
Achieving this demands comprehensive soil mapping across all agricultural land in Tanzania, coupled with digital tools that transform field-level data into site-specific recommendations. It demands research into crop-specific nutrient uptake under varying environmental conditions. It demands the infrastructure to support continuous learning and adaptation.
The Artificial Intelligence Imperative: From Data Hoarding to Data Democracy
Perhaps the most transformative opportunity lies in artificial intelligence applied to agriculture. Professor Hatibu issued a pointed challenge to Tanzania’s research establishment:
“Mahindi tani sita 15 inawezekana. Mpunga upate tani nne tu wakati 10 inawezekana. Kwa hiyo serikali na sisi ambao tumepita huku tunawapa moyo waendelee kwa sababu baa iko juu na uwezo wa kufikia upo,” he stated, highlighting the productivity gap that research must close.
More provocatively, he challenged the nation’s data governance. “Data ambayo tumeizalisha tangu tumeanza utafiti wakati wa Wajerumani kwenye mkonge mpaka sasa hivi ni nyingi mno. Ni very valuable. And if we invest and turn it into our own locally controlled AI kukisaidia kilimo tutakuwa tumekwenda mbali sana,” Professor Hatibu declared. His argument was radical: Tanzania has generated decades of agricultural research data—yet this data remains locked in filing cabinets, its value captured by international researchers.
“Kila wakati tunaangalia kwamba next level ni nini. Sisi tunatakiwa tufanye nini katika utafiti wa kilimo na utafiti wote katika Tanzania tusiogope kuenda mbele,” he urged, articulating a vision where Tanzanian researchers leverage Tanzanian data to build Tanzanian artificial intelligence for Tanzanian farmers.
He outlined a four-point agenda: first, establish national ownership of agricultural research data; second, invest in computational infrastructure (cloud computing, high-performance systems) to process this data; third, build deep expertise in machine learning and big-data analytics; fourth, establish clear governance frameworks around data quality, privacy, and access.
The investment will be substantial—computing infrastructure demands significant electricity costs. But the return is transformative: a Tanzanian AI for Tanzanian agriculture, designed by Tanzanian scientists, serving Tanzanian farmers.
The Workforce Imperative: Keeping Excellence in the Field
In his formal address, Minister of Agriculture Daniel Changolo distilled the philosophical core of this anniversary gathering. “Ukweli usiopingika kwamba utafiti ndio roho ya maendeleo ya nchi yetu,” he declared. “Bila utafiti hakuna tija. Bila utafiti hakuna mafaniki.”
Vice President Nchimbi highlighted a structural challenge that threatens to undermine a decade of progress. TARI currently employs approximately 62 researchers holding PhDs, with over 69 researchers actively pursuing doctoral studies. Yet the institute faces a sustainability crisis: many of its most accomplished senior researchers are reaching retirement age.
The solution is unconventional. Rather than enforcing mandatory retirement at fixed ages, the Government should create pathway arrangements that allow researchers of demonstrated productivity to continue contributing beyond traditional retirement thresholds. The example provided was potent: a researcher in his mid-seventies who completed a 10-kilometre run at this week’s marathon, demonstrating the vigour and engagement that should determine tenure, not chronological age.
More fundamentally, Vice President Nchimbi articulated a revolutionary principle for researcher compensation. “Matokeo yoyote na tija yoyote inayopatikana kutoka kwa mtafiti, tija hiyo ianze kumnufaisha moja kwa moja mtafiti,” he declared. He described the principle with an apt metaphor: when a meal is served and a customer tips the waiter, should the cook—who performed 90 per cent of the labour—receive nothing whilst the server pockets 100 per cent of the gratuity?
“Sio swala tu ya kuwa mtu mmoja asitake kujimilikisha 100 per cent ya matokeo ambayo yana jasho la watu wengine,” the Vice President emphasised. The Government has formalised this: any seed variety commercialised from TARI research now generates revenue that flows directly back to the researchers who developed it. This is not charity; it is the recognition that those who create value should benefit from it.
Scaling Research to the Corridors: AGCOT’s Convergence with TARI
The Agricultural Growth Corridors of Tanzania (AGCOT) brought a critical perspective to the gathering. Geoffrey Kirenga, Chief Executive of AGCOT Centre Limited, and policy specialist Prudence Karugendo represented the organisation’s commitment to translating TARI’s laboratory innovations into integrated agricultural transformation across Tanzania’s priority corridors. AGCOT’s presence underscored a central truth articulated throughout the event: research excellence means little without deployment infrastructure that connects scientific breakthroughs to farming communities at scale. The corridors serve as the implementation frontier where TARI’s 343 technologies meet the reality of smallholder production, market linkages, and value chain integration.
The Private-Sector Partnership Challenge
One critical gap persists: whilst government has doubled its commitment to research infrastructure, private sector investment in agricultural research and development remains marginal. Professor Hatibu noted that large-scale food manufacturing enterprises—mills processing wheat, facilities producing cooking oils—have outpaced agricultural research in innovation and capital deployment.
Bridging this gap demands strategic partnerships. The Government should establish frameworks that allow private companies to co-invest in research aligned with their commercial interests, with revenue-sharing mechanisms that reward TARI and individual researchers when technologies are commercialised.
Beyond investment mechanics, the event surfaced a cultural imperative. “Jambo la mwisho ambalo linahitaji juhudi ni kujitangaza, celebrate your successes,” a senior researcher urged the assembled officials. The argument was simple yet profound: research communities thrive when their achievements are recognised and celebrated publicly—not merely published in international journals, but honoured by the nation and its leaders.
Ten Years of Foundations; Twenty-Five Years of Transformation
The 10th anniversary of TARI is not a moment of completion but of inflection. The institute has established itself as the scientific backbone of Tanzania’s agricultural sector. Its technologies are in fields across the country. Its researchers are publishing globally. Its infrastructure is modernising. Its mandate is clear.
But the hard work lies ahead. The leap from four per cent annual growth to ten per cent; from 30 per cent post-harvest losses to five per cent; from raw commodity exports to value-added products that generate billions in farmer income—these transformations demand sustained research investment, integration with private enterprise, and a national commitment to treating science not as an afterthought but as the foundation upon which all agricultural progress rests.
Vice President Nchimbi’s closing statement crystallised the fundamental premise of the gathering—and of Tanzania’s development trajectory over the next quarter-century:
“Utafiti ndio roho ya maendeleo ya nchi yetu. Utafiti ndio roho ya matokeo chanya ya utekelezaji wa dira ya 2050. Bila utafiti hakuna tija. Bila utafiti hakuna mafaniki. Tunazijaribu tunakisia au tunafanya bila kuwa na uhakika wa matokeo. Lakini kwa utafiti tunajijengea uhakika wa kuyapata matokeo tunayoyakusudia.”
Research is not a luxury. Research is the foundation upon which Tanzania’s agricultural transformation rests. And for TARI, for the corridors, for every farmer across this nation, that foundation is now undeniably solid.
For TARI, for Tanzania’s farmers, and for the 2050 vision that will define the nation’s agricultural future, those words are both a mandate and a benediction.
The 10th anniversary celebration of the Tanzania Agricultural Research Institute took place during the Nane-Nane (8 August) celebrations in Dodoma, attended by Vice President Emmanuel Nchimbi, Minister of Agriculture Daniel Changolo, and agricultural stakeholders from across Tanzania’s research, private sector and farming communities.
