Rice is commonly consumed as food around the world. It occurs in long-, medium-, and short-grained types. It is the staple food of over half the world's population.. Hazards associated with rice consumption include arsenic from the soil, and Bacillus cereus which can grow in poorly-stored cooked rice, and cause food poisoning.
The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. [1] The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice.
Rice polyculture is the cultivation of rice and another crop simultaneously on the same land. The practice exploits the mutual benefit between rice and organisms such as fish and ducks: the rice supports pests which serve as food for the fish and ducks, while the animals' excrement serves as fertilizer for the rice.
There is one thing that distinguishes 60-year-old Vo Van Van’s rice fields from a mosaic of thousands of other emerald fields across Long An province in southern Vietnam’s Mekong Delta: It isn ...
Organic farming typically reduces some environmental impact relative to conventional farming, but the scale of reduction can be difficult to quantify and varies depending on farming methods. In some cases, reducing food waste and dietary changes might provide greater benefits. [ 43 ]
Predictions of climate change's effects on rice cultivation vary. Global rice yield has been projected to decrease by around 3.2% with each 1 °C increase in global average temperature [142] while another study predicts global rice cultivation will increase initially, plateauing at about 3 °C warming (2091–2100 relative to 1850–1900).

In the late 1600s and early 1700s, tidal swamps bordering rivers were cleared and diked to grow rice. During its peak, 5 million bushels of rice were produced in the United States, and 70% was ...
