On a recent trip to Vietnam, Tony Bartlett, ACIAR's Forestry program manager, witnessed farmers' success of incorporating acacias and fruit trees into their farming systems...
Convincing poor farmers to include trees in their agricultural systems to improve land management is much easier if there are good prospects for them to achieve sound financial returns within 5 or 6 years. But there is never likely to be one tree-based system that will provide the best option to all farmers in a country. ACIAR forestry research aims to help farmers find the trees that work best for their situation.

Probably the most successful example involves growing Acacia woodlots, where an estimated 250,000 farmers have adopted this forestry system into their overall farming. It is estimated that in 2012 about 70% of Vietnam’s 1.2 million hectares of acacia plantings were owned by smallholders with an average holding of just 3 hectares.
The Vietnamese farmers grow the acacias on a 6-year rotation and then sell the wood for conversion to woodchips – there is a strong export market to China for pulp and paper making.
In Vietnam, acacias generate a total of US$4.3 billion per year from pulpwood sales. Over the past 20 years, ACIAR has supported research on domesticating and improving the germplasm used in Vietnam’s acacia forestry system. Mr Stephen Midgley, one of the Australian scientists who has worked with Vietnamese forest scientists for most of this time, says that forestry research is a long-term business, but it can result in significant financial returns for farmers.

So there are more than a quarter of a million Vietnamese farmers earning the equivalent of extra adult's wage simply by incorporating Acacia trees into their farming system.

One promising system involves the use of a native fruit tree (Son Tra) and fodder grasses. The project team has collected germplasm from the best fruiting trees and provided grafted Son Tra trees to the Hmong ethnic farmers involved in the trials. These grafted trees should produce large fruit crops in only two or three years. The fodder grasses are used to improve the nutrition of the farmers’ cattle, which are an important part of the farming system.
The project team has also been working with farmers to establish cooperative marketing arrangements for the Son Tra fruit into high-value markets in Hanoi.

The potential economic benefits that can come from this system are quite significant. The farmers participating in the group marketing scheme have been receiving at least double the farm-gate price for their Son Tra fruit – so for the same effort they get twice the return simply by being better connected to a market.
One farmer we visited in Tuan Giau district, Giang Dung Vu (pictured left), told us that he makes about VND 10 million per year from his best Son Tra tree. This is enough money from just one tree for the farmer to buy himself a new motorbike each year (if he so wanted!).
If the project can improve the yields and quality of Son Tra fruit as well as establish better marketing arrangements, farmers’ incomes will likely increase even further, and more farmers will become interested in this agroforestry system.
