An international team of researchers have built a set of machine learning models they say can help predict global food shortages in the near future, helping governments and international agencies understand where they can best help. Scientists from the World Food Programme, University of London Mathematics Department and Central European University Department of Network and Data Science, made use of a "unique global dataset" to build machine learning models that can explain up to 81 percent of the variation in insufficient food consumption. The study claims the machine learning models draw from indirect data sources in areas such as food prices, macro-economic indicators (including GDP), weather, conflict, prevalence of undernourishment, population density, and previous food insecurity trends. The aim is to create near-term forecasts, or "nowcasts." "We show that the proposed models can nowcast the food security situation in near real-time and propose a method to identify which variables are driving the changes observed in predicted trends -- which is key to make predictions serviceable to decision-makers," the research paper published in Nature Food this week said. The outputs of the ML models have been used to create a world map including near-term food insecurity forecasts called HungerMap.
