How much of the world lives on subsistence farms?

Approximately 2.5 billion people, or about one-third of the global population, depend on subsistence farming for their livelihoods. This practice is particularly prevalent in developing countries, where families grow food primarily to feed themselves rather than for sale. Subsistence farming plays a critical role in food security, especially in rural areas, but it often faces challenges like climate change, land degradation, and limited access to resources.
