Forest management in Cambodia: an overview4
60% of the national territory is covered by forestsWoody biomass is still the main cooking fuel in Cambodia: it represents the main fuel in rural households (almost 100%) and the most popular one in urban households (almost 60%)Population growth and limited access to electricity put an extra burden on woody biomassBiomass is a renewable source only if the forest has time to regenerate (sustainable exploitation)High rate of deforestation may not only bring about a shortage of fuelwood but also soil degradation and impoverishment of agricultural landOverall balance between offer and demand is currently positive, there is however a discrepancy since wood energy situation varies between areas 181,035 km2country area91%of Cambodian households relyon woody biomass for cooking100,940 km2covered by forest90%of rural households have noaccess to electricity and relyentirely on biomassonly 20%of Cambodian households have access to electricitynational yearly demand of fuelwood5,500,000 tonsSource: National Census 2008, UNDP 2010, FAO 201123protected areasAnalysis of biomass energy supply and demand in Cambodia | Nov 2012 | Mathieu Ruillet

Both firewood and charcoal are outsourced
Fuelwood is collected for free from forest lands close to the villages Charcoal is bought from illegal, inefficient kilns

Charcoal production: some basic figures9
Traditional charcoal producers operate with low-efficiency technologies (i.e. ground-pit kilns) with uncontrolled carbonization processesHigh conversion ratios and low calorific values bring about a greater demand for firewoodCharcoal is produced in rural areas (mostly areas around Kirirom, southeast of Kampong Speu)Charcoal is mainly transported to and consumed in urban areas Charcoal transportation has both an economic and environmental impactDue to rarefaction of resources, price of charcoal increases steadily192,400 tonsnational demand of charcoal per year6.5 kg/1 kgconversion ratio firewood/charcoal with traditional ground-pit kiln1,251,000 tonsof firewood needed yearly to cover national demand of charcoal48%of national demand for charcoal comes from Phnom Penh26.4 GJ/toncalorific value of charcoal produced with traditional ground-pit kiln15.6 GJ/toncalorific value of fuelwoodSource: GERES Cambodia analysisAnalysis of biomass energy supply and demand in Cambodia | Nov 2012 | Mathieu Ruillet

Demand management of biomass energy:households and household-scale industry12
Households and household-scale industries are the biggest consumers of firewood in CambodiaBiomass consumption for domestic cooking in rural and urban areas accounts for more than 50% of Cambodian energy consumptionHousehold-scale industries have a limited thermal efficiency (18-24% according to the industry), which could be improved by utilizing efficient stoves and kilnsImproved stoves and kilns are expensive and difficult to afford for households and household-scale industries84%of Cambodian households use firewood for cooking purposes3.135 kgan average ruralhousehold consumes every day7%prefer charcoal1.543 kgof charcoalof firewoodan average urban household consumes daily2.1 kgof firewood3.11 kgof charcoalSource: GERES Cambodia analysis and monitoring tests, National Census 2008Analysis of biomass energy supply and demand in Cambodia | Nov 2012 | Mathieu Ruilleta palm sugar industryconsumes daily104 kgof firewooda rice wine distillery42.5 kg

Demand management of biomass energy:the case study of garment and brick factories14
Demand from small and medium-size industries in Cambodia is a threat to a sustainable forest managementSupply from old rubber plantations is almost exhausted, industries are using other types of wood and biomass energy fuels (especially rice husks)Improved machinery (e.g. boilers for ironing in the garment industry) could be employed to increase the overall energy efficiency of the industrial processes and reduce the demand for fuelwoodOther potential measures comprise the reutilization of industrial wasteSource: GERES Cambodia analysis, UNDP 2010, IFC studyAnalysis of biomass energy supply and demand in Cambodia | Nov 2012 | Mathieu Ruillet1,600,000 m3obtainedannually from abandoned rubber plantations to supply brick, tile and garment industry69garment factories in Cambodia, corresponding tovolume of fuelwood consumed per year by 273,000 tons3,900 haper year40brick factoriesvolume of fuelwood consumed per year by 50,000 tons750 haper yearin Cambodia, corresponding to

Main points and next steps20A sustainable biomass energy chain would represent a valuable way to secure a self-sufficient energy supply to one targeted sector (e.g. households and HSIs) and can be viewed as a development driver for Cambodia on the long runSustainable balance between biomass energy supply and demand is at stakeFocus on four main areas of intervention:FOREST MANAGEMENTCHARCOAL PRODUCTIONDEMAND MANAGEMENTALTERNATIVE SOURCINGFor any of these areas there are already some projects being implemented by development agencies and constraints preventing those projects from having full positive impact on the balance between biomass energy supply and demand
