The idea of food self-sufficiency - where a country produces enough food to meet the needs of its people without heavily relying on imports - has become very important globally. With world trade often disrupted by issues like political problems, climate change, and pandemics, many countries are reconsidering the need to produce their own food. Some nations, such as the United States and Australia, are highly self-sufficient due to large farmlands and favorable weather. However, in crowded regions with limited farmland, reaching food self-sufficiency is difficult.

  食料の自給自足、つまり輸入に大きく依存することなく、国民の需要を満たすだけの食料を国内で生産するという考え方は、世界的に非常に重要になってきています。政治問題、気候変動、パンデミックなどの問題によって世界貿易がしばしば混乱する中、多くの国が自国で食料を生産する必要性を再考しています。米国やオーストラリアなどの国は、広大な農地と恵まれた気候のおかげで、高い食料自給率を誇っています。しかし、農地が限られた人口密集地域では、食料の自給自足を達成するのは困難です。
