Meet Sakhiwe Shongwe and Bonkhe Mahlalela, the 2012 Scientific American: Science in Action Award winners. Sakhiwe and Bonkhe were born and raised in Swaziland, and have experienced first-hand some of the environmental problems facing their country, in particular the challenges faced by subsistence farmers struggling to feed their families. Their desire to combat these challenges lead them to hydroponic farming (farming without soil). They developed a low-cost method of hydroponics, tested it against the standard subsistence farming method, and found their method lead to a 140% increase in yield.
