Hello dear friend @lemouth, the farms of 4 hectares have a moderate space for the management of animals, you could use two hectares and manage a very small herd of animals, the rest of the two hectares can be used to establish a house and crops of vegetables, cassava, bananas, a space for laying hens, pigs and others as mentioned in the article.
I particularly think that a well diversified farm of 4 hectares can support a family of 8 to 10 people and even more, as long as it is properly managed.
For example, the hens lay eggs every day, the milk from the cows can be used to produce products such as cheese, curd, butter and meat. With a well synchronized management you can support the family and even market the surplus.
The ideal is to implement management that does not generate high costs. See you later, have a great week.
