Macro-economic tailwinds are at our backs. By 2050, the world's population is expected to expand to 9 billion people. We're at more than 7 billion today. That growth will come mostly from emerging economies, such as China and India, where incomes are increasing, and diets improving. An increased demand for food, fuel, and fiber will require an approximate doubling of agricultural output in that timeframe.
Also expected to continue is the migration from rural areas to cities. In 2010, for the first time in history, over 50% of the world's population lived in cities. By 2050 that number is expected to reach 70%. A smaller labor pool in rural areas creates the need for more mechanized farming, as manual labor is replaced by more productive equipment solutions. Increasing urban populations also creates the need for housing, roads, bridges, and other infrastructure investments.
