Rice Farming

A Case Study By Mike

Some Essential Facts About Rice

Rice requires the following things to grow:

•Temperatures above 21˚C

•More than 2000 mm of rain a year

•Flat land

•Fertile Alluvium soil

Rice is a staple food for one third of the worlds population. This means that it is in very high demand.

Rice also has a growing season of 5 months so with the correct temperatures and rainfall it is possible to grow twice a year.

Case Study-South East AsiaBangladesh, located near

Nepal on the tropic of Cancer, is an ideal location for rice farming because temperatures are above 21˚C for 11 months of the year, ranging from 20˚C in December to 35˚C in May.

However, the monsoon season lasts only 4 months from June to September. This is a problem because rice requires a constant supply of water for the entire five months it takes to grow.

Most of Bangladesh is a delta so it is flat land which means the fields can be easily flooded for growing rice.

In Bangladesh, the main rivers are the Ganges, the Megna and the Brahmaputra.

Fortunately, irrigation is used to take water from nearby rivers to farms to ensure a supply of water for the rice to grow.

Without this the rice would not have enough water to grow.

Irrigation is the process of taking water from one place to where it is needed. This is usually done with irrigation ditches that are basically trenches connected to an existing water supply.

In South East Asia, rice farming is largely subsistence and is very intensive, this means that whole families work on the farms and then live off the crops for the rest of the year. However, some years there is an excess or they have managed to yield two crops of rice so they can sell this for a small amount of money.Most of the real labour is transporting and planting the rice which requires being bent over for long periods of time. It has been described as back breaking. This is done by the women mostly as they are seen as inferior to men.

Rice Padis – How They Work

Rice padis are fields with barriers that prevent water getting out so that the rice can grow. They are used in South East Asia to ensure a constant supply of water. Because the rainy season is only 4 months long, inadequate for rice.

•First, animals are allowed into the fields to graze which clears stubble of the last crops and fertilises the soil.

•Then the bunds and canals are repaired which will trap and move the water.

•Then the seeds are planted in nursery beds to allow them to grow to seedlings.

•The padis are flooded and ploughed. •The seedlings are moved into the padis. •The rice is gradually weeded and thinned until it ripens after 5 months. •The rice is then harvested. The rainy season must be over for this.
