WASHINGTON — The scenes witnessed by journalists and humanitarian workers in recent months have been striking: In Sudan, swollen-bellied babies are looking for anything to eat. In Yemen, where warring parties have blocked humanitarian aid, hollow-eyed children and their mothers languish on the brink of death from starvation. In Ukraine, the elderly are collecting rancid rain runoff for drinking water.
Malnourishment and hunger were big problems even before Russia invaded Ukraine in February and cut off Europe's breadbasket from its markets, sparking a flurry of dire warnings about the world's food supplies. Dozens of countries across the globe are already suffering from devastating food shortages, so much so that the number of people facing starvation more than doubled in just the last two years, to 345 million, according to United Nations figures.
The causes are myriad: drought and flooding, and the interruption of supply chains triggered by the COVID-19 pandemic, especially in China. An estimated 20 wars or conflicts — the latest in Ukraine — have also seriously disrupted access to food and water.
