World Bank President David Malpass on Tuesday urged advanced economies to boost food aid to developing countries, and work to increase production of food, energy and fertiliser to address shortages and rising prices caused by Russia's war in Ukraine, reported Reuters.

Malpass, speaking at an event with International Monetary Fund chief Kristalina Georgieva, said cash payments or vouchers would be a good way to help farmers in poor countries buy fertiliser to ensure continued food production.

Georgieva said the crisis was exacerbating the divergence between rich and poor countries, and said it was also critical to diversify the production of food, energy and fertilizer supplies to reduce dependence on Russia.
