Weeds (quelites) as food crop

.• San Bartolo del Llano, Ixtlahuaca,

México.• Quelites.– 74 quelite species all useful.– Used as food, fodder, medicinals,

etc.– 4.5 kg quelite/family/month.– One hectare of milpa produces

1,5 t/ha of quelite and represents 25% of the total value of maize ( approx 200 dollars).

Peasants, industrial agriculture and Agrobiodiversity

Who feeds us today???

Family farmers in Brasil

• Control 24 % of arable land• 84% of the farms• Give three times more employment than

agribusiness• Produce 87% cassava, 70% beans, 46% maize,

50% poultry and 59% swine

Small biodiverse are more productive

• Small farms are much more productive than large farms if total output is considered rather than yield from a single crop.

• Biodiverse farms which produce grains, fruits, vegetables, fodder, and animal products out-produce yield per unit of single crops such as corn (monocultures) on large-scale farms.

• Productivity in polycultures developed by smallholders in terms of harvestable products per unit area is higher than under sole cropping with the same level of management
