“Smart” targeting of fertilizer subsidies in Kenya: Productivity, welfare, and soil health

“Smart” targeting of fertilizer subsidies in Kenya: Productivity, welfare, and soil health

Fertilizer subsidy programs in the Global South often juggle competing policy objectives of maximizing aggregate production and providing social protection for the poorest households. Using 2026 survey data from 3105 Kenyan households paired with parcel-level soil tests, this paper evaluates the targeting performance of Kenya’s National Fertilizer Subsidy Program (NFSP). Specifically, we analyze the extent to which the current “de facto” targeting—driven by digital registration and e-vouchers—aligns with these possibly conflicting policy goals. We find that the subsidy recipient populations who would maximize productivity do not tend to include the poorest and most vulnerable farmers. Furthermore, the current pool of NFSP beneficiaries shows limited overlap with the ideal beneficiaries for either policy objective. Among those who we would ideally target, we find that factors such as mobile phone ownership and knowledge of fertilizer recommendations may help predict which households actually receive benefits. We conclude that integrating soil testing into subsidy frameworks could significantly reduce these inefficiencies and improve the alignment between program delivery and national agricultural goals.

Targeting of beneficiaries in chemical fertilizer subsidy programs: State of knowledge and evidence gaps

Targeting of beneficiaries in chemical fertilizer subsidy programs: State of knowledge and evidence gaps

Low- and middle-income countries are under increasing fiscal pressure to rationalize spending on fertilizer subsidy programs. Policy reforms shifting expenditure away from subsidies can have beneficial impacts given the well-documented distortionary market effects and negative environmental externalities of fertilizer subsidies. However, such reforms also result in losses and often lower fertilizer use for current beneficiaries. Understanding who is impacted by reform thus requires an assessment of who is currently benefiting, yet there is little systematic work understanding who these programs currently benefit both on paper and in practice. In this paper, we identify low- and middle- income countries with active fertilizer subsidy programs, and characterize the targeting regime of each program based on both explicit and implicit criteria determining eligibility. Then in a selection of case studies, we explore which individuals are receiving subsidy benefits in practice. We find that while many fertilizer subsidy programs are designed as universal, in many countries there are implicit targeting criteria embedded in the way subsidy programs are implemented and/or informal targeting induced by supply shortfalls. Further, we find evidence that regardless of targeting regime, the targeting of subsidy programs is generally pro-poor, driven by the fact that the poor are often concentrated in the agricultural sector.

How much do our neighbors really know? The limits of community-based targeting

How much do our neighbors really know? The limits of community-based targeting

Social assistance programs in developing countries often rely on local community members to identify potential beneficiaries. As community members may observe neighbors’ welfare, their reports may capture transitory shocks better than the proxies typically observable by a centralized policy implementer. To test this, we conduct a lab-style experiment in Central Java, in which participants rank other community members’ welfare, using benchmarks that vary in sensitivity to transitory shocks, and target small cash transfers. We find little evidence that community-held welfare information better reflects transitory shocks and find that targeting decisions mostly depend on perceived differences in overall wealth.
