Fertilizer subsidies in Malawi: From past to present

Fertilizer subsidies in Malawi: From past to present

Malawi has been at the center of the debate on agricultural input subsidies in Africa ever since it significantly expanded its fertilizer subsidy program about two decades ago. When it did so, Malawi was a trailblazer, receiving international attention for seemingly leveraging the subsidy program to move the country from a situation characterized by food deficits and widespread hunger to crop production surpluses. In this paper we trace the history of Malawi’s subsidy program over the past 70 years, describing how the country arrived at that watershed moment earlier this century and how the subsidy program has developed since. We show how donor support for the program has wavered and how external pressure to remove the subsidy has repeatedly been unsuccessful. We also demonstrate how over the years the program’s total fiscal burden has fluctuated significantly. However, we find that since the expansion of the subsidy program in 2004, the fiscal costs of the program have shown little correlation with the maize harvest that same agricultural season. We show that the subsidy program has succeeded in raising awareness about the value of the fertilizer for increased crop productivity. However, despite its continued prominence in the country’s agricultural policy, most Malawian smallholder do not manage to grow sufficient maize to feed their households throughout the year, and every year millions depend on food assistance during the worst months of the lean season.

Welfare impacts of seasonal maize price fluctuations in Malawi

Welfare impacts of seasonal maize price fluctuations in Malawi

Maize prices fluctuate significantly throughout the year in Malawi, creating winners and losers depending on who is selling and who is buying the staple at different times. We link maize market price data to nationally and temporally representative household survey data on maize sales and purchases to quantify welfare gains and losses throughout the year. A stable maize price would lead to only a modest increase in Malawi’s total social surplus when summed across a whole year, but a dramatic reduction in hunger during the lean season. We discuss policy options to smooth maize prices throughout the year.

El Niño: Malawi’s harvest of its staple food maize may fall by 22.5% this year

El Niño: Malawi’s harvest of its staple food maize may fall by 22.5% this year

Maize is the preferred staple of most of southern Africa. In Malawi it supplies two-thirds of national calorie intake. Nine out of 10 farming households produce maize and devote over 70% of their land to growing it. Most farming households are vulnerable to the rainfall patterns. Over 90% of farming households in the country rely solely on rain to irrigate their maize plants. We looked at possible weather pattern changes driven by El Niño – an unusual warming of surface waters in the eastern tropical Pacific Ocean – and their impact on maize production in Malawi. We did this by developing a model from historical district crop data and El Niño events since the 1980s. Econometric modelling, which uses statistics and mathematics, is useful in studying the cause and effect of relationships, in the case of weather patterns. Historically, two out of every three El Niño events have coincided with reduced maize harvests of, on average, 22.5%.
