Dr. Hailemariam Ayalew Tiruneh is a Research Fellow in the Development Strategy and Governance Unit. His research is in the microeconomics of development with a focus on the impact evaluation of different policy interventions on smallholder farm households in developing countries.

Before joining IFPRI, Hailemariam worked as a Departmental Lecturer/Assistant Professor in Development Economics at Oxford University. In collaboration with the International Maize and Wheat Improvement Center (CIMMYT), he was a Marie-Curie postdoctoral research fellow at Trinity College Dublin. Hailemariam received his Ph.D. and MSc in Economics from the University of Copenhagen, Denmark. In 2015, he was a visiting scholar and research fellow at the East African Social Science Transition (EASST) at the University of California in Berkeley. He also worked as a short-term consultant at the World Bank and a senior consultant at DAI Global (UK).

How Kenya can boost agricultural productivity with fertiliser subsidy

How Kenya can boost agricultural productivity with fertiliser subsidy

Kenya has a long history of implementing fertiliser subsidy programmes aimed at supporting smallholder farmers. These initiatives have evolved over the years, from targeted programmes for resource-poor farmers to broader, non-targeted schemes like the the National Fertiliser Subsidy Programme (NFSP) implemented in 2022 to boost food production and stabilise prices in the wake of global supply chains disruptions related to the Russia-Ukraine conflict and the Covid-19 pandemic. The NFSP provides subsidised fertiliser to all registered farmers, with the quantity allocated based on the size of registered land holdings. To assess the impact of the NFSP on farm productivity, researchers collected data in main maize producing counties and conducted appropriate econometric analysis to isolate the effect of fertiliser subsidy on maize yield by accounting for other factors such as seed, rainfall, access to credit, irrigation, gender, education, etc.

Revisiting the size–productivity relationship with imperfect measures of production and plot size

Monitoring smallholder agricultural productivity growth, one of the targets of the Sustainable Development Goals, rests on accurate measures of crop production and land area. Existing methods and protocols for measuring smallholder production and plot size are prone to various sources and forms of mismeasurement. Inaccuracies in production and land area measurement are likely to distort descriptive and predictive inferences. We examine the sensitivity of empirical assessments of the relationship between agricultural productivity and land area to alternative measurement protocols. We implement six production and six land area measurement protocols, and show that most of these protocols differ systematically in their accuracy. We find that an apparent inverse size–productivity relationship in our data is fully explained by measurement error in both production and plot size. Moreover, we show that some of the previously used “gold standard” measures are themselves prone to nonclassical measurement error, and hence can generate spurious inverse size–productivity findings. Our results also show that slight improvements in the precision of objective measures significantly reduce the inferential bias associated with the size–productivity relationship.
