The prices of staple grains began rising in mid-2020, reflecting higher fertilizer prices and the supply chain bottlenecks caused by the outbreak of Covid-19, and increased sharply following the Russian invasion of Ukraine in early 2022. How have these dramatic increases in world prices of cereals affected poverty in low-income countries? This brief estimates the impact of higher world grain prices on poverty in Niger. Other briefs in this series examine the impact of higher food prices on poverty in Kenya, Ethiopia, Nigeria, Burkina Faso, and Mali (see Minot and Martin, 2023a and 2023b; Martin and Minot, 2023a, 2023b, and 2023c).
All six studies use a similar approach. First, we examine the effect of the rise in international cereal prices on the real price of key grains in the domestic markets of the country. Second, we estimate the impact of the changes in domestic grain prices on the real income of each household using nationally-representative survey data, taking into account the importance of the commodities in consumption and as a source of income for each household. Finally, we estimate the changes in headcount poverty (the share of people living below the poverty line) based on the changes in real income for each household in the sample. We focus on the prices of maize, wheat, and sorghum for reasons discussed below.

Kenya is potentially very vulnerable to sharp increases in the prices of key staple grains such as maize and wheat, both because these are important in diets and because Kenya depends on im ports of these products. A first step in understanding the impacts of changes in the prices of these products is to examine developments in their prices on world markets. After a long period of rela tively stable prices on world markets, the prices of key food staples began to rise from around the beginning of 2020. This period of price increases, spanning the COVID-19 pandemic and then the price shocks following Russia’s invasion of Ukraine raised serious concerns about the welfare of poor people in countries such as Kenya. Figure 1 shows the movements in the prices of four key grain staples—maize, rice, sorghum and wheat—from the beginning of 2020.

The fate of the Black Sea Grain Initiative is again in jeopardy. The collapse of the Nova Kakhovka dam last month has flooded cropland along the Dnipro River and disrupted irrigation. Meanwhile, the ammonia pipeline from the Russian Federation to the Ukrainian port of Pivdennyi has also been damaged. The pipeline has not been in operation since the start of the war; however, its reopening has been a key demand of the Russian Federation to renew the grain deal. While these events are not likely to have major impacts on grain supplies in the short term, they further increase tensions that could result in a termination of the agreement later this month. This would reduce Black Sea exports and further reduce Ukraine production incentives.
