The Suitability of Earth's Land Area for Arable Farming

What percentage of Earth's land area is suitable for arable farming?

Choose one of the following:

a) Approximately 67% of Earth's land area
b) Approximately 33% of Earth's land area
c) Approximately 50% of Earth's land area
d) Approximately 25% of Earth's land area

Answer:

b) Approximately 33% of Earth's land area

Approximately 33% of Earth's land area is suitable for arable farming. This means that one-third of the Earth's total land area has the appropriate conditions for growing crops and sustaining agricultural practices.

The land that is suitable for arable farming is characterized by factors such as fertile soil, adequate water supply, favorable climate conditions, and accessible terrain. These areas are crucial for food production and supporting human livelihoods around the world.

Arable farming plays a significant role in feeding the global population and providing essential crops such as wheat, rice, corn, and vegetables. It contributes to food security, economic development, and environmental sustainability.

Efforts to protect and enhance arable land are essential for ensuring future food security and adapting to changing environmental conditions. Sustainable agricultural practices can help maintain the productivity of arable land and reduce the impact of farming on the environment.
