While the country is well positioned to tap into new export markets, volatile weather conditions, land reform issues and a legacy of neglect continue to hinder agricultural output, preventing the Philippine agriculture sector from reaching its true potential. David, C. C. 1983. The master plan states that total forest cover in 1990 was 6.694 million ha; however, the Philippine–German Forest Resources Inventory Project (Forest Management Bureau, 1988) concluded that forest cover in 1988 was only 6.461 million ha. Coconut trees occupy much of the steepest nonarable land at lower elevations. Fast-growing hardwoods such as gmelina are also integrated into contour hedgerow systems. High levels of biomass production also tend to exacerbate competition for nutrients and water with the adjoining food crops and reduce cereal crop yields (D. P. Garrity and A. Mercado, International Rice Research Institute, unpublished data). Philippine economic performance in regional perspective. (1990) compared the changes in crop yields associated with planting a double row of leguminous hedgerows by a group of 10 farmers who adopted the system and a control group of farmers who did not. A 50-Year Development Program for the Philippines. 266–283 in Keepers of the Forest: Land Management Alternatives in Southeast Asia, M. Poffenburger, ed. Research status on management and utilization of acid soils in the Philippines. They also provide a good foundation for soil conservation efforts, so that farmers may subsequently diversify into more labor-intensive hedgerow enterprises, including those that grow perennials, leguminous trees, and improved forages. Fitzken Da Vinci M. Niro, Evaluation of Modified Coconut Husk Claveria, Misamis Oriental Province (Mindanao), Philippines. Colleges of agriculture and forestry need to be encouraged to set up joint academic and research programs targeted to upland ecosystems. Costello, M. A. Quezon City, Philippines: Department of Agriculture. Power Take Off-Driven Mobile Biomass Shredder, Design, Fabrication, and The Philippine lumber industry. Given the exceptionally high production and marketing risks in the uplands and the generally low marginal returns, a number of alternative enterprises must be undertaken on upland farms to provide stability (Chambers, 1986) and to take maximum advantage of the complementarities that occur among income-generating activities (for example, leguminous trees for fodder, green leaf manure, and fuelwood; cattle for labor, cash income, and manure). FAO. The 15 largest islands make up 94 percent of the total land area. They also provide high-quality forage during the dry season. Johnson, N., and J. Alcorn. The system involves a crop sequence of three crops of maize monoculture per year but only one primary tillage operation annually. Many studies have shown significant benefits from maintaining a surface mulch. 209–228 in Nutrient Management for Food Crop Production in Tropical Farming Systems. Technology covers the technical solutions and the institutional capabilities to develop them. An organizing force was critical to the eventual development of these leases. It lays out a framework for forestland management over the next 25 years. Overgrazing during the regrowth period reduces ground cover and makes grassland the most significant source of soil erosion in the Philippines. Pernia, E. M. 1988. Implementation of a successful community forestry program will be an immense organizational task that will require a strong commitment by the forest occupants and upland farmers. Natural forest regeneration is prevented by a range of prevailing factors: fire in uncultivated logged-over areas and ranch areas, grass succession and loss of tree seed in shifting cultivated areas, and permanent conversion to agricultural fields in intensively farmed areas. Of the 18.6 million people who lived in the uplands in 1988, 6 million had lived there before 1945, 2 million had migrated there between 1945 and 1948, and 10 million had migrated there since 1948 (Lynch and Talbott, 1988).
