The food and livelihoods of many rural people depend on combinations of crops, livestock, forestry and fisheries, and still information on these mixed systems is scarce. Rural households in low- and middle-income countries earn almost 70% of their income through mixed production systems . These systems produce about half of the world's cereals, most of the fruits, vegetables, pulses, roots and tubers, and most of the staple crops and livestock products consumed by poor people in lower-income countries . They can help in adapting to climatic risks and reducing GHG emissions by improving nutrient flows and improving the recycling of nutrients within the production system and by increasing food production and diet quality per unit of land and diversifying income sources . Indigenous groups often practice mixed production, integrating crops, animals, fisheries, forestry and agroforestry through traditional ecological knowledge.
