自給農業
Subsistence agriculture can be used as a poverty alleviation strategy, specifically as a safety net for food-price shocks and for food security. Poor countries are limited in fiscal and institutional resources that would allow them to contain rises in domestic prices as well as to manage social assistance programs, which is often because they are using policy tools that are intended for middle- and high-income countries. Low-income countries tend to have populations in which 80% of poor are in rural areas and more than 90% of rural households have access to land, yet a majority of these rural poor have insufficient access to food. Subsistence agriculture can be used in low-income countries as a part of policy responses to a food crisis in the short and medium term, and provide a safety net for the poor in these countries.
