New evidence in SOFI 2018 confirms a rise in world hunger: the number of people who suffer from hunger has been growing over the past three years returning to levels from almost a decade ago. Multiple forms of malnutrition are evident in many countries: adult obesity is growing even as forms of undernutrition persist. The report says that climate variability and extremes are key drivers behind this rise together with conflict and economic downturns and are threatening to erode and reverse gains made in ending hunger and malnutrition. SOFI 2018 reveals new challenges on the road to Zero Hunger while setting out urgent actions needed to achieve the goal by 2030.
