Politicians and billionaires are advocating geoengineering approaches as quick fixes on challenges of climate, biodiversity and environment. Many of these technologies are too dangerous to be deployed or even experimented with in the real world.

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.

Bhutan couldn’t achieve its goal of becoming a 100% organic country by 2020 despite the best of intention, strong political will and government support. What challenges have prevented Bhutan from achieving its goal and does it still or ever have the chance of achieving the goal?

Sri Lanka is in the midst of arguably the worst economic crisis during its 74-year post-independence era, with its political and social stability strained to almost breaking point. One facet of this crisis is shown in the Sri Lankan agriculture sector, which is trying to recover from the self-inflicted wounds of a misguided policy of overnight conversion to exclusively organic agriculture (EOA). The author analyzes the background that led to such an ambitious, but unrealistic, venture and describes its wide-ranging repercussions, which have put the country’s food security and farmer livelihoods under serious threat.

Even with unprecedented global investment and effort by some of the world’s most expert professional genetic engineers trained in the task of taming SARS-COV2, it is clear that just one virus continues to surprise and outwit humans’ best attempts to control biology and that social divisions are increasing as a consequence. Here we explore what other technologies would-be molecular manipulators are developing as part of their ongoing mission for human mastery.

The world is never short of food supply issues. They become headlines on economic and political pages, as when the US food price index surged 3.1-4.2% in 2021, and China urged its people to stock up on food ahead of winter. Scientists have resorted to plant-based meat, cultured meat and genetically engineered plants to mitigate food shortages. The author believes that some emergent food technologies are promising in terms of addressing the problems of feeding the poor, biodiversity, and climate change, yet there are also new challenges to be resolved.

Debates revolving around the high cost and economic viability of CCUS technology, as well as what critics call “a false solution”, have been around for years. Does CCUS deserve the bad name though? And is its potential worth the wait?

Indonesia has long faced the serious issue of land grabs, driving indigenous and rural communities into conflict with plantation, forestry and infrastructure developers. Could digitising land records and national geospatial information help resolve overlapping claims to land, and promote agrarian reform in Indonesia?

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’.
