  • Indonesia is the largest rice consumer. Rice consumption is 140kg of rice per person per year.
  • - MDG1: eradicate poverty and hunger.
  • - Challenges for agroforestry systems to provide food in mix-planting between trees and crops.

  • Drivers for deforestation at landscape level:
  • Land conversion (to oilpalm plantation, industrial forest plantation (HTI),
  • rubber monoculture, transmigration area, shifting cultivation (land grabbing)),
  • (ii) Logging activities (stopped in 2000)
  • (iii) Mining (coal)

Species Density and Richness

  • Species richness and density of sapling were higher in RAF-60, while for pole was higher in shrub-30 and for tree was higher in forest.
  • RAF-13 and RAF-30 had higher density but also had lower species richness than other landcover types.
  • Low species richness was influenced by the high dominance of rubber in every rubber agroforest site.

It is shown that in lower stratum, species level grow in RAF is more similar to forest .

challenges of agroforestry system for food security
Challenges of agroforestry system for food security
  • Tree based agroforestry, such as rubber agroforest, provides foods, mainly fruits, nuts and spices.
  • Trees providing carbohydrate and protein (such as bread fruit, jack fruit, candle nuts, etc.) can be enriched with enrichment planting.
  • Taungya system provides annual crops, such as upland, vegetables, spices, etc.
  • Promoting new variety of crops with light intolerant, such as paddy and soybean, that can be grown under canopy.
