Several billion dollars invested, a significant portion with no measurable results. Across all microloans dedicated to agricultural irrigation in sub-Saharan Africa between 2010 and 2025, a majority have not produced documented productivity gains. The primary cause is that many loan recipients do not possess a recognized land title. Without property rights, capital remains dead capital.

The Essentials

  • Several billion dollars have been invested in irrigation microloans in sub-Saharan Africa (2010-2025); a significant portion has not produced documented productivity gains.
  • A significant share of credit recipients do not have a land title.
  • The absence of title prevents farmers from offering collateral and lenders from assessing risk: credit is either poorly allocated or blocked.
  • Pathways exist—digital cadastres, collective titles, alternative guarantee systems—but their deployment remains marginal.
  • The challenge by 2030-2035: determining whether land reform can precede or accompany the influx of capital, rather than awaiting its results.

Credit Irrigates Banks, Not Fields

The reasoning seemed sound. Giving small African farmers access to cheap credit to finance irrigation equipment would lift the most immediate constraint: water. Yields would increase, income would follow, food security would improve. This scenario convinced dozens of donors, from the World Bank to the French Development Agency, passing through hundreds of NGOs and microfinance institutions.

The result is disappointing. Several studies compiled by CGIAR centers, including IWMI (working paper 185, 2018), document a systematic gap between stated objectives and measured effects. Credit did circulate. Equipment was sometimes purchased. But productivity, measured in yield per hectare or net agricultural income, did not follow in the majority of cases.

Credit lands on a deficient institutional terrain that absorbs it without transforming it, because it is not the only missing input.

Without Land Title, Capital Remains Without Effect

Joseph Stiglitz described this mechanism with precision in his work on information asymmetries and failing markets. In People, Power, and Profits, he shows that financial markets function well only when underlying institutions—property rights, enforceable contracts, symmetric information—are in place. Without them, credit is misallocated: lenders cannot assess risk, borrowers cannot offer collateral, and capital ends up concentrating where risk is already low, that is, far from the most vulnerable.

In sub-Saharan Africa, this abstraction takes a concrete form. A farmer who has cultivated the same plot for thirty years, who inherited it from his father, who feeds his family with his harvests, may have no legal title to this land. He holds it by customary right, by the recognition of his community, sometimes by a verbal agreement with a local chief. This is enough to live. It is not enough to borrow.

Without title, he cannot mortgage his land. Without a mortgage, the lender has no collateral. Without collateral, the loan is either not granted, or is granted at rates reflecting maximum risk, or is granted by institutions that compensate for the absence of land collateral through other mechanisms—joint liability, prior savings—which proportionally reduce productive investment capacity.

The AFD study on micro-irrigation in sub-Saharan Africa documents this cycle. Agricultural households with access to formal credit without land title tend to use the funds for short-term needs—consumption, occasional inputs—rather than for lasting investments such as drip irrigation systems. The investment horizon aligns with tenure insecurity: if you can lose your land tomorrow, you do not install pipes today.

Land Security Conditions Investment Horizon

Field studies comparing similar farms, with and without recognized land title, show significant investment gaps. Titled farmers invest more in lasting soil improvements, in more expensive but more efficient equipment, in long-cycle crops that better valorize water.

Farmers without title maintain practices yielding immediate returns, more resistant to uncertainty but less productive over the long term.

This behavior is rational. A farmer without title knows that his rights can be contested, that the state can expropriate without solid recourse, that land conflicts, frequent in several regions of sub-Saharan Africa, can cause him to lose land on which he just invested. Prudence is not peasant irrationality: it is an adaptation to real institutional insecurity.

The issue transcends agriculture. The same dynamics weaken the ecosystems on which this agriculture depends: without clear rights, the management of common resources—water, forests, pastures—becomes conflictual and overexploited. Land insecurity thus worsens soil degradation and pressure on water resources, making it even more difficult to deploy efficient irrigation systems.

A Real Debate Between Land Reform and Credit Pragmatism

The institutional reading defended by Stiglitz is not unanimous. Some liberal economists and development practitioners would argue that waiting for complete land reform before deploying credit amounts to indefinitely postponing aid to the poorest. Tyler Cowen and proponents of market pragmatism emphasize that financial innovations can partially circumvent the absence of title: solidarity savings groups, alternative scoring systems based on repayment history, group mutual guarantees have sometimes enabled capital allocation where formal institutions were lacking.

The argument has weight. In certain contexts, these mechanisms have worked. Microfinance in Bangladesh, tontines in West Africa, agricultural cooperatives in certain regions of Ethiopia show that intermediate solutions exist.

But the available data for sub-Saharan Africa over the past decade nuance this optimism. Financial innovations have expanded access to credit. They have not, in several documented cases, converted this access into sustained productivity increases. The reason lies in the capital intensity of irrigation: a drip irrigation system, even simplified, represents an investment of a different nature than a consumption loan. It requires a long horizon, solid collateral, and minimal certainty about the right to exploit the irrigated land.

Financial innovations compensate for collateral shortages for small amounts in the short term; they do not replace land rights for heavy investments in the long term.

The data here favor the institutional reading: credit alone, without land reform, produces marginal effects on agricultural productivity at large scale.

Programs Beginning to Correct the Diagnosis

The good news is that the diagnosis now circulates within development institutions, and concrete responses are emerging.

The World Bank has integrated land tenure security as a prerequisite condition in several of its agricultural programs in East Africa since 2020. Ethiopia launched a national digital land certification program that has titled over 14 million plots in a decade, using GPS tablets and village databases. The effects on agricultural investment are documented: titled operators invest more and access formal credit more easily. Rwanda followed a similar trajectory with its Land Tenure Regularisation program, completed in 2013, which now covers nearly the entire agricultural territory of the country.

These experiences show that large-scale land reform is feasible in reasonable time, including in difficult institutional contexts. The cost is modest compared to the billions deployed in agricultural credits without results. AFD finances land tenure security components in several programs in West Africa, in conjunction with agricultural microfinance schemes. CGIAR itself now recommends that any irrigation credit program include a prior or parallel phase of rights security.

Intermediate approaches are also developing. Collective titles granted to farmer groups allow rights recognition without imposing individual privatization incompatible with customary systems. Formalized rural leases, even temporary ones, provide sufficient security to justify medium-term investments. Participatory cadastre platforms, like those tested in Senegal and Mali with EU support, allow customary rights to be mapped and made enforceable, without resorting to a classical individual title.

Results for 2030 on These Investments

The conversion of capital already deployed into sustained agricultural productivity depends on the quality of current programs; a new generation of better-designed programs may prove necessary.

The 2030-2035 horizon is what major development institutions have set for measuring the impact of current programs on African food security. Two trajectories are emerging, though no available source allows them to be calculated precisely.

In the first, ongoing land reforms—Ethiopia, Rwanda, Kenya, Senegal—accelerate sufficiently to create a critical mass of titled beneficiaries capable of productively absorbing future credit. Microfinance institutions adapt their products to prioritarily target these farmers. Green climate capital accumulating in sustainable development funds finds absorption conditions. This trajectory requires coordination between land reformers and financial operators that institutional silos have largely prevented thus far.

In the second, land reforms remain fragmented, limited to a few pilot countries, insufficiently financed and politically fragile due to local interests profiting from land opacity. Credit programs continue to be deployed according to disbursement logic rather than impact logic. The billions already invested remain largely dead capital, and the next billions risk the same fate.

The gap between these two trajectories depends less on the quantity of available capital than on the quality of institutions receiving it. The relevant signal by 2030 will be the number of secured plots, the rate of formal land coverage in target zones, and the share of credit programs conditioning access to prior rights security, rather than the amount of newly announced funds.

The dynamic recalls what is observed in other environmental domains: investing in resources without securing usage rights produces limited effects. Peatlands, reefs, and aquifers follow the same logic as agricultural plots: without governance of rights, environmental capital degrades despite financing.

Land Reform as Condition, Not as Distant Horizon

The most effective documented programs share a common architecture. They begin by mapping and securing land rights at the local scale, articulating customary law and formal recognition. They then integrate credit products adapted to actual agricultural cycles, with long maturities for irrigation equipment. Finally, they include access to markets, roads, storage, and guaranteed prices, allowing increased productivity to be valorized.

None of these three elements functions alone. Credit without land does not produce productivity. Land without credit remains symbolic recognition. Productivity without market access does not translate into income. It is the articulation of all three that creates the conditions for agricultural progress.

Donors who have integrated this systemic logic are restructuring their programs. The World Bank, AFD, and the International Fund for Agricultural Development (IFAD) display more integrated approaches in their new financing cycles. The test will be in the 2030 figures: yields measured on plots of farmers who benefited from title, rather than billions disbursed.
