Farmers had trees on farms for• fodder• fuel• fruits• fertilizer• small and large timber• Sale of goods for income generation• In bad crop years, emergency, special needs

• 600 plywood units• Purchase 1 million US$ day-1• Value added 3 million US$ day-1• 60000 man days day-1• 2.5 million $US as tax month-1
Other Environmental Benefits• CO2 sequestration• Increase in tree cover (8%)• Alleviation of pressure from Natural Forests• Biodiversity conservation• Ex situ production
The MAI realized under Agroforestry for species such as Poplar and Eucalyptus• Poplar 10 -25 m3 ha-1 year-1 (Haryana and UP)• Eucalyptus 8-14 m3 ha-1 year-1 (Haryana)• ITC Clonal Eucalyptus 35 m3 ha-1 year-1 (AP)• ITC Clonal Eucalyptus 22 m3 ha-1 year-1 (Haryana, under trial)
Biodiversity conservation• Medicinal plants• Global trade > 100 billion $US• Unsustainable harvest• Over exploitation• Extinction?• ex situ cultivation• Land???
