For more than six decades, the Tengeru Institute of Community Development (TICD) has trained people to work at the intersection of communities, government and development.
Established in 1963, the institution has evolved into a higher-learning centre offering programmes from certificate to master's level in fields including project management, community development, climate change, gender, local government and finance.
That history gave particular weight to a public lecture held at the institute in Tengeru, Arusha, on Aug. 14, when the discussion moved from the theory of community development to a question increasingly central to Tanzania's economic ambitions: how can the country mobilise enough capital and expertise to build infrastructure while ensuring that investment translates into higher productivity and better lives?
David Kafulila, Executive Director of the Public-Private Partnership Centre, offered an answer rooted in a philosophy that has long defined TICD “People-Centred Development.”
His argument was that Tanzania's development challenge is not simply a shortage of infrastructure or money. It is the need to connect infrastructure, capital, institutions and human capability.
“Development is meaningful when infrastructure and investment change people's lives and increase their productive capacity,” Kafulila told academics and students gathered for the lecture.
That distinction matters as Tanzania pursues the long-term ambitions of its Vision 2050, which seeks to transform the country into a more productive, inclusive and competitive economy.
For Kafulila, the debate should not be whether Tanzania should invest in people or in physical infrastructure.
From Nyerere to Vision 2050
Kafulila began his argument by travelling back to the country's independence struggle. He invoked the thinking of Tanzania's founding president, Julius Nyerere, who placed the welfare and productive capacity of citizens at the centre of national development.
Nyerere's argument that ignorance, disease and poverty were among the principal obstacles to development remains relevant, Kafulila said, even though Tanzania's economy and institutions have changed dramatically since independence.
The development vocabulary has changed too. The Millennium Development Goals gave way to the Sustainable Development Goals, while climate change, digitalisation, demographic growth and private capital have become increasingly important to economic policy.
Yet the underlying question remains the same: what is development ultimately supposed to achieve?
Kafulila's answer was clear. Infrastructure is a means, not the final measure of success. A road has economic value because it allows farmers to reach markets, workers to travel and businesses to reduce transport costs.
A port matters because it facilitates trade. Electricity matters because it allows households and enterprises to produce.
Water infrastructure matters because it improves health and reduces the time communities spend securing basic services.
The asset itself is therefore only the beginning of the economic story. Its real value emerges when people are able to use it productively.
The human capital equation
That is why Kafulila placed human capital at the heart of his presentation.
He identified three fundamental elements; nutrition, health and knowledge as essential to building a productive population.
The logic is economic as much as social. A worker who is healthy is more likely to be productive. A child who receives adequate nutrition and education has a greater chance of becoming a skilled worker.
A population with relevant knowledge is better positioned to adopt technology, establish businesses and respond to changing economic conditions.
“Human capital is the engine of the economy,” Kafulila argued, stressing that people with health, nutrition and knowledge are capable of creating solutions even when resources are limited.
That creates a two-way relationship between people and infrastructure.
Infrastructure can increase productivity, but productivity also generates the incomes, taxes, skills and demand required to sustain infrastructure.
The danger, therefore, is treating the two as competing budget priorities.
A country that builds roads without developing the skills to exploit them may create physical connectivity without sufficient economic transformation.
Likewise, a country that invests heavily in education and health without creating productive infrastructure can struggle to convert human capability into economic opportunity.
Tanzania's challenge is to avoid that imbalance.
Why PPP is becoming more important
This is where public-private partnerships become relevant.
Tanzania, like many emerging economies, faces a widening demand for infrastructure and public services while government resources remain finite.
The state must finance education, healthcare, water, energy, transport and other social priorities.
At the same time, businesses require infrastructure capable of supporting trade, manufacturing, logistics and investment.
Kafulila argued that PPP can help bridge that gap by allowing government and private investors to bring different strengths to the same project.
The private sector brings capital, technology, management and commercial discipline.
Government brings regulation, public policy, oversight and responsibility for ensuring that projects serve the broader public interest.
The attraction of PPP is therefore not simply that it can provide another source of money.
It can also allow the government to concentrate scarce public resources on areas where commercial investors have little incentive to participate.
A commercially viable road, student accommodation facility, market or transport project may be capable of attracting private capital.
That can leave more government resources available for hospitals, medicines, schools and other services where social returns may be high but direct financial returns are limited.
In that sense, PPP becomes a tool for prioritising public resources rather than merely supplementing them.
But the model comes with risks.
Private capital does not automatically guarantee public value.
Poorly designed contracts can create expensive obligations for governments, while weak regulation can undermine service quality or shift excessive risk to taxpayers.
The quality of institutions therefore becomes as important as the amount of capital mobilised.
The institutional advantage
That point formed another important strand of Kafulila's argument.
Countries do not become wealthy simply because they possess oil, gas, minerals, land or other natural resources. They become wealthy when institutions are capable of converting those assets into sustained economic value.
Tanzania’s development depends not only on investment, but on strong management, governance, skills and accountability. In PPPs, sound financial models and private capital cannot replace proper project preparation, effective regulation or capable institutions. Infrastructure can only deliver lasting value when it is well managed, maintained and aligned with public needs.
This makes developing professionals who understand both the commercial and social dimensions of development increasingly important—and reinforces TICD’s role in building that capacity.
Why TICD's PPP curriculum matters
The institute's leadership said it has incorporated PPP-related modules into its training programmes as part of efforts to prepare graduates for a development environment in which government, business and communities increasingly have to work together.
The move reflects a broader shift in the country's development architecture. PPP projects require more than financiers.
They need project managers, economists, lawyers, community-development specialists, environmental experts, gender specialists, local-government professionals and people capable of assessing how an investment affects communities.
TICD’s academic programmes provide a strong foundation for supporting PPP development. Its expertise in project management, finance, climate change, gender and community development can strengthen project preparation and implementation. Its local-government experience can also help ensure that investments respond to community needs and deliver wider benefits.
The result is a broader conception of PPP — not simply as a financial transaction, but as a multidisciplinary development instrument.
Womenomics and the missing half of productivity
Kafulila highlighted the economic role of women, arguing that Womenomics should view women not simply as beneficiaries, but as workers, entrepreneurs, farmers, investors and employers. Better access to education, healthcare, finance, markets and productive assets can raise household incomes and expand national productivity.
The same principle applies to Tanzania’s growing youth population. A healthy, educated and employed workforce can become a demographic dividend, while inadequate investment can increase pressure on public services and finances.
For Tanzania, investing in people should therefore be treated as economic infrastructure, essential to converting population growth, inclusion and development investments into sustained productivity and broader economic opportunity.
The demographic pressure behind the debate
Kafulila warned that Tanzania's population growth will place increasing pressure on the state's capacity to provide basic services.
The implication is straightforward.
More people require more schools, hospitals, water systems, energy, transport and jobs.
If the government attempts to finance all of that infrastructure on its own, competing demands could stretch public finances.
PPP can help bring private capital into projects with commercial potential.
But capital alone will not solve the problem.
The country will also need enough skilled workers to build and operate those projects, enough businesses to use the infrastructure and enough consumers with purchasing power to sustain economic activity.
That returns the debate to human capital.
A partnership beyond government and business
The TICD lecture showed that PPPs should extend beyond government and private companies. Government provides policy, businesses bring capital and expertise, while universities build skills and communities contribute local knowledge. Citizens ultimately use the infrastructure and services created.
If any link fails, the investment’s economic returns can suffer. This broader partnership explains why TICD’s people-centred development philosophy remains highly relevant to Tanzania’s PPP agenda.
It forces policymakers to ask a question that purely financial assessments can sometimes overlook: who ultimately benefits?
The road to 2050
Tanzania's Vision 2050 will require much more than higher public spending.
It will require the country to mobilise domestic and foreign capital, improve productivity, strengthen institutions and develop a workforce capable of operating in a more sophisticated economy.
PPP can contribute to that transformation, but only if projects are carefully selected, transparently structured and aligned with long-term national priorities.
The private sector cannot be expected to pursue objectives that belong exclusively to government.
Nor can government expect businesses to invest without reasonable commercial prospects.
The strength of PPP lies precisely in finding the intersection between those interests.
That intersection becomes even more important as Tanzania seeks to build a larger and more competitive economy.
For Kafulila, the true measure of investment is not its size, but the economic capability it creates. A bridge should move more than vehicles; it should move opportunity. A port should connect businesses to larger markets, while a school should produce problem-solvers, not merely graduates. Likewise, a PPP should deliver more than a government-investor contract, it should create public value.
That was the enduring message from Tengeru. More than 60 years after TICD’s people-centred philosophy, Tanzania faces the same question in a new economic era: whether investments can translate into productivity through better health, nutrition, knowledge, skills and stronger institutions.
Vision 2050, in that sense, is not simply a project to build a richer Tanzania. It is a test of whether Tanzania can build the people and institutions capable of creating that wealth.
