Nutrition Early Warning System (NEWS) is one of many projects emerging out of the CGIAR Platform for Big Data in Agriculture. NEWS will aggregate and analyze satellite imagery and traditional data, such as rainfall, temperature, and vegetation health, to help predict the nutritive value of crops.
The underpinning of NEWS is machine learning, a sector of artificial intelligence that develops systems able to process large data sets and learn from those data sets in order to locate patterns. NEWS will first compile and analyze data related to food and nutrition in sub-Saharan Africa. Then, based on the analyses, the system will deploy algorithms to locate patterns and trends that could identify impending nutrition threats, like climate shocks or economic strife, and provide decisionmakers with opportunities to intervene.
News is useful for predicting and preventing a nutrition crisis before it occurs，then help inform interventions to boost nutrition in sub-Saharan Africa.
