As farm labourers, vendors and unpaid care workers, women are responsible for food preparation and production in many countries and regions throughout the world and play a vital role in food security and nutrition. However, women and girls continue to be disproportionately affected by poverty and malnutrition. Women in rural areas are particularly affected, as female-headed households continue to grow, exceeding 30 per cent in some developing countries, with women owning only 2 per cent of agricultural land and with limited access to productive resources. In many low-income countries, women are the backbone of the rural economy and 79 per cent of economically active women in the least developed countries consider agriculture as their primary source of income. Agrarian land reform legislation often discriminates against women by entitling only men over a certain age to land ownership while women's entitlement only applies in cases where they are household heads. Such discriminatory practices prevent women in many countries from asserting their economic independence and being able to feed themselves and their families.
