From New Delhi to Bangkok to Seoul, Asia is facing the world’s most serious air pollution catastrophe.  Experts say this poor air quality becomes fatal with the onset of heat waves and drought from climate change, but citizens are coming up with their own solutions to tackle the dirty air.

Nearly every country has enough solar and wind to generate its required energy. Pumped hydro makes large-scale energy storage a solved problem. Australia is a global pathfinder in solar photovoltaics. Clean hydrogen, imported from Australia, is frequently touted as a major player in the decarbonization of East Asia’s industrialized countries such as Japan and South Korea. But some of the proposed export markets for hydrogen energy are largely illusory, argues Australian National University engineering professor Andrew Blakers.

Corporations are now using digital tools to push methods that dominate industrial food systems, such as artificial fertilisers, mechanisation, monocultures and toxic pesticides, onto remaining small-scale farming and fishing operations. Current trends in digitalisation threaten biodiversity, the wider environment and human health, yet there are few challenges to the tech industry’s hype about a ‘fourth industrial revolution’.
