Industrial sector (e.g. tea plantations) also have high fuelwood demand
Background
Research methods to facilitate agroforestry-based small business
• Quantitative and qualitative social research methods to describe the fuelwood economy
• Field, laboratory and consumer trials to evaluate a range of candidate SRC species for their value in fuelwood and charcoal production
• Participatory action research methods to facilitate the establishment charcoal producer-vendor groups

Fuelwood Survey
Fuelwood survey methods• Questionnaire survey of urban and
rural domestic users (n= 3,966) and sellers (n=156)
• Case study monitoring of actual daily fuelwood use over two one-week periods (n=36)
• Semi-structured interviews of commercial and industrial users and institutional stakeholders
(n = 76)

Survey conclusions• Fuelwood use here to stay foreseeable future• Economy is large, informal, simple and flat with few
intermediaries between collector and seller.• Main problems are access to fuelwood and transport to
market• No institutional support but no regulatory barriers or
extra costs• Great opportunity for entrepreneurs to create a more
sophisticated fuelwood supply chain that could deliver sustainably harvested and value-added fuelwood to consumers, especially in urban areas and the commercial sector.

Field evaluation of SRC species
• 10 species at 2 spacings in 3 replicated field sites (highland and lowland)
• Farmer-managed woodlots and alley-farm systems
• Laboratory tests of burning quality of wood and charcoal
• Consumer preference • Market performance

What highlanders think of fast-grown firewoodWe asked some landholders to cook with our fast-grown firewoods which took only 2 years to grow.
We asked them to compare these fast-grown firewoods with the slow-grown firewood they normally collect.
This is what they said for each of the 7 trees we gave them
Eucalyptus grandis• less smoke• better heat, long burning• coals last the same• easy to split and use
Eucalyptus robusta• slightly smokier• very good heat, long burning• coals die quicker• remove bark before use
Eucalyptus pellita• smoke the same• not as hot or long burning• coals die quicker• not good for starting fire
Leucaena• smoke the same• not as hot or long burning• coals die quicker• very good to start fire
Calliandra• much less smoke• not as hot or long burning• coals die quicker• very good to start fire
Local Yar• smoke same• heat same• coals same• easy to split and use
Indonesian Yar• slightly smokier• better heat, long burning• coals last long• difficult to split

Charcoal producer-vendor method• Advertise for participants• Training activities in:
– Small business planning– Charcoal production– Charcoal stove construction– Nursery techniques for SRC species
• Action research– Groups develop own business plan and
group structure– Guidance with microcredit loans– Monitoring and guidance of group progress
• Promotion of charcoal concept• Semi-Structured interviews in community
development sector to survey existing models of collective business engagement (n=41)

Conclusions
• Inter-Disciplinary approach essential for complex problems
• Facilitation of small-business requires: – long term commitment– training and support across whole value-chain– respect and adaptation for regional cultural
differences • Need for formal recognition and support by
national and provincial governments

** Gender equity index = ratio of the relative proportion of instances of female activity in relation to the region sample size, to instances of male activity. Within a region, if men and women share the load equally in collecting and buying fuelwood, i.e. a 1:1 ratio, then the index = 1.0 . If there are more instances of men’s activity then index <1, if women more active >1. A change in 0.1 units of the index reflects a change in 10% of the regional population.
