hildren across much of Europe have been going back to school for the start of a new year, but in many other parts of the world, coronavirus restrictions have kept classrooms closed. We've taken a look at the situation in India and its neighbours in South Asia where the United Nations estimates nearly 600 million children have been affected by lockdowns. Who's not going back to the classroom? When coronavirus restrictions were first imposed in March and April, it was at the start of the academic year in many South Asian countries. School classrooms across the region were closed down, and these restrictions have largely remained in place. Currently: In India, classrooms are largely closed, with teaching being done remotely. However, the government says students from grade 9 to 12 can go into schools on a voluntary basis with their parents' consent from 21 September if they need support Bangladesh and Nepal have extended school closures and will continue to rely on remote learning Sri Lanka's schools reopened in August after trying to reopen in July, but then closing after a spike in cases Children in Pakistan will return to school in phases, starting on 15 September as coronavirus case numbers have fallen Who has access to the internet? Remote learning involves either live online classes for students, or digital content which can be accessed at any time - offline or online. But many South Asian countries lack a reliable internet infrastructure and the cost of online access can be prohibitive for poorer communities. The UN says at least 147 million children are unable to access online or remote learning. In India, only 24% of households have access to the internet, according to a 2019 government survey. In rural parts of India, the numbers are far lower with only 4% of households having access to the internet. Bangladesh has better overall connectivity than India. It's estimated that 60% can get online, although the quality of broadband internet is often very poor.   There is also a lack of basic equipment in many schools. Nepal's latest Economic Survey report says that of the nearly 30,000 government schools, fewer than 30% have access to a computer, and only 12% can offer online learning. Some countries have turned to television and radio for those with no internet-enabled devices or broadband access. These platforms have much greater penetration per head of population. India's public broadcaster, Doordarshan, has been broadcasting daily educational content through its television channels and radio services.Bangladesh's government broadcaster, Sangsad television, also airs recorded classes on its channels.
