Global shocks to fertilizer markets: Impacts on prices, demand and farm profitability
研究了2021-2022年化肥价格飙升对全球化肥需求及农场盈利能力的影响，发现全球需求仅小幅下降，但非洲低收入农民受影响更严重。
• Supply chain disruptions caused major spikes in fertilizer prices during 2021–2022. • Globally, the price shocks only had a muted impact on fertilizer usage. • On average, profitability for commercial crop producers was affected only mildly. • Farmer profitability in low-income Africa was affected more severely, however. • Low usage makes African smallholders less vulnerable to fertilizer supply shocks. During 2021–2022, spiking fertilizer prices raised fears that fertilizer application would drop around the world, leading to lower crop production, higher food prices, and greater food insecurity. Even writing mid-2024, a paucity of data impedes a full assessment of how the underlying global market shocks may have affected farmers and food production around the world. Using proxy indicators for fertilizer demand and farm profitability, we find that despite the steep increase in input costs, global demand for fertilizer fell only modestly during the 2022–2023 crop cycle, suggesting many (commercial) farmers were able and willing to absorb increased input costs in the context of generally good harvest prospects and, at the time, high crop prices. However, we also find the fertilizer price spikes have not been felt equally, with many farmers in Africa estimated to have been affected more adversely, even though with varied impacts also amongst those farmers.
