GMO crops are marketed as providing quick fixes to complex problems, writes Julia Wright. But they only perpetuate 'business as usual' farming that's depleting soils, water and biodiversity, and entrench unsustainable models of agriculture in place of agroecological systems that work with, not against, nature.
Climate change will impact the world in many ways, writes Matthew Blackett. Some of them may be good, like more rain in African drylands and coral atolls adapting to rising seas. But most of them - like coastal flooding, long term drought, earthquakes and stronger tropical storms - will be very challenging. We must increase the resilience of the most vulnerable countries without delay.
