Challengesofagroforestrysystemforfoodsecurity
• Treebasedagroforestry,suchasrubberagroforest,providesfoods,mainlyfruits,nutsandspices.
• Treesprovidingcarbohydrateandprotein(suchasbreadfruit,jackfruit,candlenuts,etc.)canbeenrichedwithenrichmentplanting.
• Taungyasystemprovidesannualcrops,suchasupland,vegetables,spices,etc.
