1
The economics of forest plantations and on-farm planting as a rural income-generating activity Claire Coote Issues for the Sustainable Use of Biomass Resources for Energy, Colombo, August 2005
2
Compare UK & Sri Lanka Situation Both islands, net energy importers, forestry sector not a major industry but important in certain regions Both recent converts to need for biomass generation In UK driven by need to reduce carbon emissions, plus interest to support rural areas In Sri Lanka driven by need to reduce fuel imports and extend power supply to more people, plus interest in improving rural livelihoods
3
Sri Lanka: Considerable experience in biomass production & use Knowledge of species and seed selection for fast growth rates, calorific value Woodfuel management techniques to maximise efficiency Smallholder expertise should not be overlooked Need to consider possible association with low efficiency and drudgery
4
UK: Short Coppice Rotation Despite Energy Crops Scheme subsidy farmers been slow to invest Unused to crops without annual payment Key is establishment of end users Need for more research to increase yields & provide better idea of costs and returns Support to producer groups appears successful Some concerns about visual impact
5
The TV Bioenergy Coppice Contract Growers decides no. of hectare (3 ha min) Grower controls crop husbandry and management TVBC guarantees index-linked min price £36/odt Grower can become shareholder in group TVBC assist with planting, harvesting & transport TVBC contract for 10 years (3 harvests) TVBC provides technical and support services Grower must be located in certain region Grower pays small annual membership fee Source: www.tvbioenergy.co.uk
6
UK: SRC Costs & Returns Need to compare costs and returns of alternative farm enterprises: gross margin GM usually based on one year’s figures SRC income not received each year so equivalent annual value (EAV) calculated EAV estimate £203 - £287 Lower than GMs for arable crops Comparable GM with upland sheep farming
7
UK SRC: other considerations Price paid per oven dried tonne: £30-40 Farmers have to pay for chip drying & haulage Conflict of interest between growers & power generators Generators able to pay £25 – 35/tonne Growers need £30 – 60/tonne
8
Sri Lanka: Gliricidia SRC Grown in two farming systems Coconut intercrop on plantations Intermittent planting on smallholdings Estimated revenue of Rs.9 per tree per annum
9
Sri Lanka: Gliricidia SRC Need more information on costs of production, including opportunity cost of labour Particularly for women Must consider pest control including goats and cattle Need to value additional benefits
10
Economic Costs & Benefits Societal viewpoint Employment creation Import substitution of fossil fuel Local economic development

12
Social Issues Understanding why people grow trees Keeps land in productive use Trees may be planted where lack of capital prevents farmers from growing more capital- intensive crops Diversification of farm production Provide products and income in between crop harvests Concerns over growing trees as cash crop – fears of land being withdrawn from essential food production
13
Social Issues 2 Land tenure and security of tenure Lack of secure tenure has been assumed to inhibit tree growing Evidence from other countries that this is less critical than other factors – credit, markets Sri Lanka experience with poor establishment of farmer woodlots due to lack of lease agreements with Forestry Dept.?
14
Social Issues 3 Existing uses of so-called scrub/waste land Need to investigate if this land is used e.g. for grazing Animal herders may resent trees planted and set fire to them
