Final answer:
Malawi's success with fertilizer subsidies affirms their importance in boosting agricultural productivity and contradicts advice from international organizations that suggested relying solely on free markets.
Step-by-step explanation:
The story of Malawi's agricultural transformation supports the view that fertilizer subsidies are crucial for improving agricultural productivity. By implementing subsidies for fertilizer, Malawi was able to revitalize its overfarmed and depleted soils, thereby enhancing food security. This move contrasts with the advice from the World Bank and other international bodies that advocated for a reliance on free market principles without such subsidies. However, policies in many high-income countries, including their own agricultural subsidies, often harm low-income countries by distorting global prices and undermining local agriculture.
