Global hunger has fallen more than a quarter since 2000, but conflict and climate shocks are beginning to reverse these gains, an annual global hunger index said on Thursday.
According to the index, nearly half of the 119 countries surveyed had “serious”, “alarming” or “extremely alarming” hunger levels between 2012 and 2016.
It showed war-torn Central African Republic worst affected, followed by Chad, Sierra Leone, Madagascar and Zambia.
“Conflict and climate-related shocks are at the heart of this problem,” said Dominic MacSorley, chief executive of Concern, which compiled the report along with the International Food Policy Research Institute and Welthungerhilfe.
The index aalso showed that about half of the populations in the hungriest countries were short of food.
South Sudan and Somalia, which are at risk of renewed famine, were among 13 countries excluded from the index due to lack of data.
The UN said in September that global hunger levels have risen for the first time in more than a decade, now affecting 11 per cent of the world’s population, or 815 million people.
The UN said famine struck parts of South Sudan earlier this year, and there is a high risk that it could return there and develop in other countries hit by conflict: northeast Nigeria, Somalia and Yemen.
Yemen came sixth in the index as its hunger crisis has spiked since 2015 when civil war erupted and the data covers the period 2012 to 2016.
Although most of Nigeria is relatively food secure, the eight-year Islamist Boko Haram insurgency has left millions in the northeast at risk of starvation.
“We must build the resilience of communities on the ground, but we must also bolster public and political solidarity internationally,” MacSorley said in a statement.
The survey found that 14 countries, including Senegal, Azerbaijan, Peru, Panama, Brazil and China, have made significant improvements since 2000.
The index is based on levels of hunger in the general population, and rates of wasting, stunting and deaths among children under five years old.
Women, girls and ethnic minorities are most at risk of hunger, which causes nearly half of deaths in under fives, it said.
“The world needs to act as one community with the shared goal of ensuring not a single child goes to bed hungry each night and no-one is left behind,” MacSorley said.
