I. Background
2
Indonesia has the world’s largest area of rubber (Hevea brasiliensis) plantations (3.5 million ha) and is the world’s second largest natural rubber producing country (2.7 million tons in 2007)
• Indonesia’s rubber plantations are
mainly dominated by smallholder farmers (<5 ha) which make up for 86% of the 3.5 million hectares of rubber’s area
• 7 million farmers in Kalimantan and Sumatera depend on rubber for their livelihood
4
• 64% rubber area still under traditional mixed system using unselected rubber seedlings (jungle rubber), with low latex productivity but provision of multiple products and services.

Background (continued)
8
• Intensive monoculture rubber with high yielding rubber clones offers higher latex productivity but requires high capital and labour input.
• Improved Rubber Agroforestry System (RAS) developed and promoted by the World Agroforestry Centre (ICRAF) incorporates clonal rubber in traditional agroforestry setting improves latex productivity while maintaining benefits of traditional system.
Rubber Agroforestry System
Objective
9
RAS technology is becoming popular among smallholder rubber farmers, but its adoption is still slow and limited; farmers
cite multiple reasons for this.
The objective of the study is to identify the factors that influencing the adoption of improved rubber agroforestry system by Rubber Smallholder Farmers in two provinces in Indonesia.

Factors in adoption
14
Incentives; Government support
The rubber farmers have limitations in capital and establishment of clonal rubber needs higher costs, therefore they depend on incentives from the government.
Factors in adoption
15
Income
The positive and significant signs for income indicated the higher the level of income the more the likelihood of rubber farmers applying clonal rubber. Introduction of improved technology such as clonal rubber is important for rubber smallholders’ farmers
01/02/11
Demonstration Plots• the adoption of clonal rubber is higher
for farmers who had observed successful demonstration plots.
• farmers are influenced by exhibitions of demonstration plots
• the more farmers observe and are involved in demonstration plots, the greater their chance of adopting clonal rubber because they acquire more knowledge and more confidence to adopt clonal rubber.
01/02/11
Land (Scarcity of land)
• a decreased land area increased their
eagerness to adopt clonal rubber in order to increase land productivity.
• Adoption of clonal rubber for higher yield on a small parcel of land was one of the alternatives to increase rubber yield
• to increase their income from the limited area of land.
Conclusions & Recommendations
18
The logit analyses show the significant factors that influencing the adoption of clonal rubber are availability of incentives, demonstration plots, higher income and scarcity of land.
This study suggests that the farmers with incentives and higher incomes will be more capable of buying clonal seedlings, fertiliser and pesticides therefore more opportunity to adopt clonal rubber.
Adoption and application of clonal rubber for higher yield on a small parcel of land was one of the alternatives to increase rubber yield and to increase their income from the limited area of land.
The Government needs to provide more incentives, access to credit, access to information and assistance, to produce more reliable, affordable and high quality of planting materials.
Demonstration plots have to be established, easy to access by farmers and good demonstration may increase farmers chance of adopting improved rubber agroforestry.
