  1. Trees with edible parts in forest and agroforests in Jambi landscape Hesti L. Tata, Subekti Rahayu, HartiNingsih World Agroforestry Centre (ICRAF-SEA) World Agroforestry Centre

  2. Presentation Outline: • Population vs rice production • Rubber agroforests (RAF) • Brief description of research sites • Tree diversity of forest and RAF • Trees with edible parts • Similarity between forest and RAF • Challenges of agroforestry systems World Agroforestry Centre

  3. Population vs Rice Production Source: Statistics Indonesia, 2012 • 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.

  4. RUBBER AGROFOREST Complex RAF Rubber monoculture Simple RAF World Agroforestry Centre

  5. Site characteristics World Agroforestry Centre

  6. 2008 Landcover change in Bungo district in 1973-2008 Source: Landscape Mosaic Bungo Team (2008) • 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)

  8. 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.

  10. Beneficial trees in RAF and Forest World Agroforestry Centre (Source: Lehebel-Peron, 2008)

  11. Similarity Index between Forest and RAF in various location in Jambi It is shown that in lower stratum, species level grow in RAF is more similar to forest . World Agroforestry Centre

  12. 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.
