    UN report: Our world has entered an era of "water bankruptcy"
    2026/01/30
    A UN report declares that the world has entered an era of global "water bankruptcy," with irreversible consequences. The report warns that many societies have been using water faster than nature can replenish it, and that the situation is so severe that old terms like "water crisis" or "water stressed" simply don't capture the full magnitude anymore. What does a global water bankruptcy really mean? Why is it happening? And can we restructure this debt before it's too late? Zhao Ying speaks with Wu Changhua, President of Global Climate Academy and Chair of the Governing Council of the Asia Pacific Water Forum.

  • Can we dim the sun to cool the Earth?

    Can we dim the sun to cool the Earth?
    2026/01/02
    As global temperatures continue to rise due to greenhouse gas emissions, can we dim the sunlight to cool the Earth? The idea may sound extreme, but solar radiation management, or solar geo-engineering, has already become a serious subject of scientific research. And it's not just scientists—billionaires like Elon Musk and Bill Gates have also shown interest. How viable is this concept in practice? What ethical, environmental, and global governance challenges could it bring? Zhao Ying speaks with John Moore, a research professor at the Arctic Center, University of Lapland in Finland. From 2015 to '22, he led the Chinese geoengineering research program while serving as Chief Scientist at the College of Global Change and Earth System Science, Beijing Normal University.

  • Are solar panels from China booming Africa's energy transition?

    Are solar panels from China booming Africa's energy transition?
    2025/12/19
    For years, critics in Washington and Brussels have warned about China producing "too many" solar panels. But could this so-called "overcapacity" actually be the key to solving Africa's energy crisis? A recent report by global energy think tank Ember shows that Africa’s imports of Chinese solar panels surged by 60% in the year leading up to June, marking the first signs of a solar take-off across the continent. Zhao Ying speaks with Dave Jones, co-founder of Ember and the author of this report, to explore the potential for solar energy to transform Africa's energy landscape.

  • What makes a city sustainable?

    What makes a city sustainable?
    2025/12/12
    Cities are home to over half of the world's population. With rapid urban growth, it becomes increasingly crucial for cities not just to survive, but to build resilience for future generations. The 2025 Global Award for Sustainable Development in Cities, or Shanghai Award, offers a glimpse of that diversity. The award is jointly organized by UN-Habitat and the Shanghai Municipality. The winners – Algiers, Al Madinah, Bogotá, Espoo, and Incheon – each show a unique pathway toward sustainable urban development. Zhao Ying speaks with Bai Xuemei, Professor of Urban Environment and Human Ecology at the Fenner School of Environment and Society, Australian National University, to explore what we can learn from their experiences.
