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.
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 [64] while another study predicts global rice cultivation will increase initially, plateauing at about 3 °C warming (2091–2100 relative to 1850–1900).

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 ...
Were rice a perennial rather than an annual species, its continuously living roots and thick cover of vegetation would prevent such erosion, just as a planting of grass can prevent a roadside slope from washing away. Perennial rice could produce critically needed food year after year on the same plot of land without degrading the soil. [23]
Management techniques range from animal management and housing to the spread of pesticides and fertilizers in global agricultural practices, which can have major environmental impacts. Bad management practices include poorly managed animal feeding operations, overgrazing , plowing, fertilizer, and improper, excessive, or badly timed use of ...

Rice paddyfields are agriculture's main contributors to greenhouse gases, which contribute to climate change, mainly because when flooded, as they often are on a regular cycle, they support methanogenic bacteria; overall, paddyfields contribute around 10% of the global greenhouse effect. Rice-fish systems may be able to contribute to global ...
