    How Nanotechnology’s Fighting Hunger

    It’s the next tiny thing. With the global population set to hit 9 billion by 2050, scientists need to boost food production. But to minimize collateral damage to the environment, some are turning to precision agriculture — targeted use of fertilizer and water — and nanotechnology. Three promising developments include nanoparticles that boost plants’ ability to absorb nutrients, nanocapsules that release a steady pesticide supply and nanosensor systems that control moisture levels. While no regulatory framework exists — and plenty of safety tests await — a green revolution to shrink tomorrow’s farming solutions is taking root.
