To promote the use of renewable energy sources, the government allows developers to turn agricultural land into solar farms, but the policy has been criticized for reducing the availability of fertile land.
The National Property Administration has approved a 600 hectare plot of agricultural land in Changhua County’s Fangyuan Township (芳苑) to be developed by five solar energy companies Farmers are protesting the decision.
In 2022, the proportion of energy generated from sustainable sources in Japan reached almost 25 percent. Solar capacity accounted for more than 10 percent of the total at 85 gigawatts, which was behind only China and the US.
There is “coopetition” — competitive cooperation — between the agriculture and solar power sectors for the use of land amid the energy transition in Japan, and there are concerns that solar panels might harm crops.
However, years of experimentation and implementation have proved that crops can grow well as long as solar farms are well designed. More than 50 kinds of fruits and vegetables had no problem in the experiments.
Tokyo has designed two pathways of energy transition: One is to permanently change the use of farmland to generating solar power; the other is to allow farming and solar generation to coexist.
Even given the small scale of power generation, the latter is considered more popular, as it creates value in agricultural landscapes, bringing them back to life and attracting young people to return to their hometowns.
This makes it a win-win situation for farmers and solar firms.
Taiwan’s nuclear-free homeland policy and the goal of achieving carbon neutrality by 2050 have driven the development of green energy. Solar panels are scattered across farmlands and fish ponds after the rapid expansion of solar projects.
Although this has contributed significantly to the efficiency of the power supply, it comes at a cost: sacrificing agricultural development, and worsening the self-sufficiency rate for grain production.
Striking a balance is the key to a win-win situation.

Taiwan’s higher education system is facing an existential crisis. As the demographic drop-off continues to empty classrooms, universities across the island are locked in a desperate battle for survival, international student recruitment and crucial Ministry of Education funding. To win this battle, institutions have turned to what seems like an objective measure of quality: global university rankings. Unfortunately, this chase is a costly illusion, and taxpayers are footing the bill. In the past few years, the goalposts have shifted from pure research output to “sustainability” and “societal impact,” largely driven by commercial metrics such as the UK-based Times Higher Education (THE) Impact
The closure of the Strait of Hormuz has sent the vast Asian chemicals industry into a tailspin. Deprived of the likes of Qatari natural gas and Saudi Arabian oil, the region’s fertilizer and plastics plants are slowing production or even shutting down. Everywhere except China, that is. In petrochemicals, China is unique. As well as a traditional industry that uses oil and gas as feedstock, it has parallel output that relies on its abundant domestic coal. Unsurprisingly, India and other regional powers want to copy and paste the Chinese method. This would not be easy — or climate friendly. The
History might remember 2026, not 2022, as the year artificial intelligence (AI) truly changed everything. ChatGPT’s launch was a product moment. What is happening now is an anthropological moment: AI is no longer merely answering questions. It is now taking initiative and learning from others to get things done, behaving less like software and more like a colleague. The economic consequence is the rise of the one-person company — a structure anticipated in the 2024 book The Choices Amid Great Changes, which I coauthored. The real target of AI is not labor. It is hierarchy. When AI sharply reduces the cost
KMT Chairwoman Cheng Li-wun’s (鄭麗文) recent visit to Beijing and her upcoming visit to Washington will serve as a high-level test of her diplomatic mettle. In Beijing, Cheng was received with symbolic gestures, a warm reception, and high-level access. In Washington, she will receive far less pomp and far sharper questions about the KMT’s vision for the future of Taiwan. Her challenge will be to persuade Washington that the KMT’s engagement with China can coexist with strong deterrence. Cheng’s April 7-12 visit to mainland China coincided with an intense period of conflict in Iran. Despite the strategic significance of Cheng’s trip,
