An Editorial in Nature Genetics 41, 635 (2009) notes that
One-sixth of the world's population does not have enough food to sustain life, and the world's food supply needs to double by 2050 without increasing demand for water or fuel. Agricultural genetics is one of the easier parts of the solution.
Agricultural genetics can help manage shortfalls in the world's food supply. Existing agricultural technologies could help give local growers access to well-tested and robust crops.
