  • The little shrub making a big difference in rural Senegal

    As climate change has brought rising temperatures and more frequent droughts to much of Africa, some communities in Senegal are finding ways to survive by adapting their agricultural practices. Medicinal plants can be harvested more frequently and sold at higher prices than traditional millet and grain. The senna (Cassia) shrub in particular has allowed farmers, especially women, to sustain economic hope and prosperity, with the added benefit of improving the health of local villagers.

  • Lessons from India in building urban resilience

    TARU, an Indian thinktank, has found that Indians cities have combined decentralized action and "multi-stakeholder engagement" in public policy to respond to problems of scarcity in water and power as well as climate change-related natural disasters. Municipalities are putting responsibility for improving local lives at the grassroots level; integrating disruptive technologies from the private sector; and fostering collaboration between government and citizens.

  • Turning CO2 into stone in Iceland

    Iceland, hit by the oil crises of the 1970s, turned to geothermal energy - and they haven't turned back. The island is now powered by 100% renewable energy, and they are taking it one step more, looking to further cut emissions using a unique carbon capture system called CarbFix. It is being pioneered at the Hellsheidi geothermal power plant in western Iceland.

  • Italy's pollution-eating cement

    Respiratory diseases caused by air pollution now account for more premature deaths in people worldwide than malaria and HIV combined. To address increasing contamination levels, particularly in cities, scientists have developed a new kind of cement that absorbs pollutants like CO2. The special cement is being manufactured in Milan, and used around in the world in cities like Paris and Chicago.

  • Vietnam's response to climate change? A shrimp and mangrove cocktail

    Increasing salinization of water sources and droughts as a result of climate change have threatened traditional agricultural practices in the Mekong Delta of Vietnam. But The International Union for the Conservation of Nature and the Netherlands Development Agency are helping teach farmers to adapt by showing them how to work with the saltier waters, establishing organic shrimp farms instead of growing rice and preserving the valuable mangroves that protect their coastline from storms.

  • The Big Green Bang: How renewable energy became unstoppable

    An economic shift to renewable energy could take decades, but thanks to rapidly evolving disruptive technologies, dropping prices of solar and wind power sources, and increasing market demand for green business, the new age of renewable energy could encompass the world economy much more quickly.
