Rice is one of the world's most important staples, with billions of people basing their meals around it. But as the world's population grows, the amount of resources needed to produce the food is growing as well.
Demand for crops such as rice, wheat and maize is set to increase by 33 percent by 2050, according to the Food and Agriculture Organisation (FAO) of the United Nations.
According to the International Fund for Agricultural Development (IFAD), it takes between 1,000 and 3,000 liters of water to produce just one kilo of rice. While this compares favorably with the 13,000 to 15,000 liters needed to produce one kilo of grain-fed beef, rice still has an impact on the environment.
