Key Points about Rice – Asia's Important Crop
What is Rice?
- Rice is a very important food for over half of the people in the world.
- It is grown in 115 countries, with China and India growing the most.
How Much Rice is Eaten?
- Rice makes up about 26% of the food people eat in Asia.
- Different countries eat different amounts:
- Bali: 0.4 kg (or 14 oz) a day
- Thailand and Vietnam: 0.3 kg (or 10.5 oz) a day
- Japan: 0.2 kg (or 7 oz) a day
- Rice is used in yummy dishes like risottos, sushi, curries, and crackers.
How is Rice Grown?
- Rice is a plant that grows in warm, wet places, usually where there's a lot of rain.
- It needs hot weather, a lot of water, and good soil to grow.
- 85% of rice needs extra water from irrigation, while 15% depends on natural rain.
Rice History
- People have eaten wild rice for over 15,000 years.
- Rice first started to be farmed in China about 9,000 years ago.
- Thanks to new farming methods, rice is now grown in many different places, like mountains and deserts.
Future of Rice Production
- The average amount of rice grown per acre (t/ha) around the world is 4.4 tons.
- Australia has the most productive farms at 10.8 tons per acre.
- New methods in China and India showed even higher yields, but researchers are checking if these can last.
Environmental Issues
Farmers are trying to solve some problems related to growing rice:
- Using too much water
- Pesticides building up in the environment
- Fertilizers washing into rivers
- Creating greenhouse gases
- Preparing for natural disasters like floods, droughts, and pests
Arsenic in Rice
- Using high-yielding rice made it easier for pests to harm crops.
- Some farmers used harmful lead-arsenate chemicals, which left arsenic in the soil and water, making it into rice.
- In Japan, farmers use ducks instead of chemicals. Ducks eat pests and weeds, help keep the water clean, and their poop acts as fertilizer. This helps farms save money and grow more rice.
