    Risks for the world’s Transboundary River Basins are projected to increase in the next 15–30 years, particularly in four hotspot regions: the Middle East, Central Asia, the Ganges-Brahmaputra-Meghna basin, and the Orange and Limpopo basins in Southern Africa.

    Among the academics I find a mix of optimism and dire pessimism. It’s a recurring theme—can we build an economic life that can preserve the planet, or is it already too late? My responsibility is to ensure that our students hear both perspectives.

  • The Climate Crisis and the Transition to a Renewable Economy

    What I am betting on is the growing sense of awareness and understanding of environmental issues among the people of the world. It could be that my personal perspective is a little warped. I’ve seen the environmental issue move from the outer fringes to the center of our political agenda.

    Does Pollution Regulation Kill Jobs? Lessons for China from the U.S.

    The problem of air pollution in China continues to reach new heights. To combat the problem in any real way stringent regulation is needed. A new paper from Columbia University’s Earth Institute finds that this can be done without hurting job creation.

  • Moving the Global Economy Toward Sustainability

    Using something finite and dumping it into a hole in the ground is less efficient and more costly than a system build on photosynthesis, renewable resources, and reuse of finite resources. In other words, an organization managed according to the principles of sustainability should be able to outcompete the organization sticking to the old, polluting…
