Table 26. Lignocellulosic Biomass Resources in the Philippines, 2000 Annual Biomass Resources Generation (tonnes) Rice hull 2,357,325 Coconut shell 1,948,867 Coconut coir 3,031,570 Coconut husk 4,330,814 Bagasse 5,985,840 Logging residues* 75,000 Total 17,729,416 Source: Biomass Atlas of the Philippines, 2000; * Logging residues include damaged wood, tops and branches, stumps, abandoned logs, and butt trimmings. Total logging residues are estimated at 104,450 cubic meters or 75,000 tonnes (assuming 1 metric ton = 1.4 cubic meters). Napier grass (Pennisetum purpureum) is one of the few dedicated energy crops being examined for biomass production in the Philippines. According to a study completed in 2001 (Samson et al.), productivity levels of 20 tonnes per ha could be achieved. If 100,000 ha were planted (representing a land area of about 4% of the maize acreage) about 2 Mt of biomass could be produced. This is about seven times the available biomass that could be supplied from sugar cane trash if harvesting occurs only after the final ratoon crop. A ratoon crop is the new cane that grows from the stubble left behind are harvesting. It enables farmers to get three or four more crop harvests before they have to replant. Biodiesel: Potential biodiesel feedstock in the Philippines is jatropha. The Department of Science and Technology (DOST) has identified about 2 million ha of unproductive and idle land nationwide suitable for jatropha cultivation. If farmers plant in field boundaries and hedges, or practice intercropping, 5 million ha could be available, producing 25 Mt of biodiesel feedstock. This would be sufficient to displace the economy’s current diesel consumption of 4.2 Mt per annum several times over. A total of 360 ha are planted with jatropha in the Philippines: 200 ha in General Santos; 27 ha in Camarines Sur; 120 ha in Fort Magsaysay, Nueva Ecija; 5 ha in 97

Dacong Cogon, Negros Occidental; and small plantations in Quezon Province (Philippines Department of Agriculture 2008). Biomass Resource Assessment Capabilities Geospatial technologies have been used by the National Mapping and Resource Information Authority (NAMRIA), an agency of the government under DENR. It is responsible for providing geospatial services and acting as the central mapping agency, depository, and distribution facility of natural resources data in the form of maps, charts, texts, and statistics. Data Availability. The Biomass Energy Laboratory at University of the Philippines at Los Baños (UPLB) has been compiling biomass resource data since its establishment in 1997. The laboratory was established by the Department of Energy, Non-Conventional Energy Division, and biomass resource assessment is one of its major tasks. A list of other agencies providing data and expertise related to agriculture and forestry is provided below: • The Department of Agriculture (DA) provides expertise and statistics on agricultural production and trade • The Forest Management Bureau (FMB) of the Department of Environment and Natural Resources (DENR) provides forestry expertise and annual statistics (since 1990) by region and province; data is collected through sample field survey • Department of Science and Technology (DOST) – Council for Agriculture, Forestry and Natural Resources Research and Development (PCARRD) and Forest Products Research and Development Institute (FPRDI) • The National Statistics Office (NSO) provides an accurate estimate of the acreage of the major commodities at a municipal level; data is collected through sample paper surveys • The Bureau of Agricultural Statistics (BAS) provides annual production data for major commodities; data is collected through sample paper surveys • The National Food Authority (NFA) updates data on rice mills and their capacities • The Sugar Regulatory Administration (SRA) reports sugar cane production and wastes data including operational sugar mills • The United Coconut Association of the Philippines provides annual data on coconut production, coconut oil mills, and oil trade 98
