How do farmers grow food around the world?
Different types of farming
In Asian aquacultures, fish from rice paddies provide as much as 70% of a persons’ protein each day.
In mixed farming systems
, one type of sustainable farming
is combined with herding, fishing or forestry activities. In a closed mixed farming system, the “waste” products of each activity provide inputs to the others while producing a diverse range of nutritious food. For example, in Zhejiang province of China, naturally flowing rivers stock rice paddies with a fish called carp, which is a major source of protein and income for farmers and their families.
Organic or ecological farming
is a type of sustainable farming where on-farm renewable resources are used as much as possible. Some small-scale farmers
are also organic farmers. Organic farmers often buy fewer resources because they use methods with on-farm resources. Sustainable farmers buy some pesticides
to get rid of crop pests
, but organic farmers will use several methods without pesticides to get rid of the same crop pest. Often organic farmers sell their surplus foods at the local market.
