Amid the Covid-19 pandemic and widespread school closures, at least one-third of students affected around the world lack access to virtual education, according to a UN study released Wednesday. In all, an estimated 463 million children lack the equipment or electronic access to pursue distance learning, said the report from UNICEF. “The sheer number of children whose education was completely disrupted for months on end is a global education emergency,” Henrietta Fore, executive director of the UN Children’s Fund, said in a statement. “The repercussions could be felt in economies and societies for decades to come,” she said. The UN estimates that 1.5 billion children worldwide have been affected by lockdowns or school closings occasioned by the pandemic.The report underlined gaping geographical differences in children’s access to distance education, with far fewer affected in Europe, for example, than in Africa or parts of Asia. The UN report is based on data gathered from roughly 100 countries, measuring public access to the internet, to television and to radio.Even children with adequate access may face other obstacles to distance education — whether the lack of a good workspace at home, pressure to do other work for the family, or a lack of technical support when computer problems arise, the UNICEF report said.
