The plan articulates a people-oriented forestry program that is sensitive to the current understanding of the complex underlying determinants of deforestation. FAO and UNEP. Upland rice and maize response in a contour hedgerow system on a sloping acid upland soil. 253–265 in Keepers of the Forest: Land Management Alternatives in Southeast Asia, M. Poffenburger, ed. Dipterocarp forests require at least 30 to 40 years for each cutting cycle, and cutting cycles are often much longer. The transferability of the CSC should, however, apply only to actual land occupants, to avoid an eventual concentration of landholdings. 1989b. Therefore, the establishment of forage grasses has been extended as an alternative to the use of leguminous tree species on contour bunds. 1967. The Master Plan for Forestry Development (Department of Environment and Natural Resources, 1990) is an important step in this direction. Effort in the field of agricultural solutions. Szott, L. T., C. A. Palm, and P. A. Sanchez. In press. Pine forests occupy less than 1 percent of the total land area (Forest Management Bureau, 1988). The major issue in permanently farmed sloping lands is how to sustain and increase farm productivity to improve the welfare of the farm population and thereby reduce the rate of migration into the remaining forested lands. TABLE 12 Estimates of Forest Cover in 2015 Based on Three Scenarios (in Hectares). Malayan Forest. FIGURE 5 Model of the evolutionary development of a small-scale upland farm on sloping land. The field is plowed on the contour, allowing the designated strips to be left as fallow vegetation. The concept of farmers producing fast-growing trees as crops was popularized in the mid-1970s by the Paper Industries Corporation of. Recommendations for developing technologies needed for sustainable agriculture. 1–14 in Second View from the Paddy, A. Ledesma, P. Makil, and V. Miralao, eds. Land Capability Classes. Control of fires on newly established plantations is difficult and costly. AN ACT REGULATING THE PRACTICE OF AGRICULTURAL ENGINEERING IN THE PHILIPPINES. 1990. 2. In fields where the technique has been implemented, the soil in runoff water is deposited at the filter strip. 1991. leaf manure for the rice crop. Multiple Cropping Research in the Philippines. Thapa, B. Sorsogon, Modification, Fabrication and Evaluation of Interval and Irrigation Method Using Rice Straw as Soil Cover on Rice Palmier, L. 1989. 1986. The natural vegetative filter strip concept may be a practical basis for the rapid, wide-scale dissemination of hedgerow technology. The approach emphasizes the interrelatedness of social and technical issues and the importance of an integrated social-technical approach to forest and agricultural development. This population includes 5.95 million members of indigenous cultural communities and 2.55 million migrants from lowland groups (Department of Environment and Natural Resources, 1990). Although data are not strongly reliable, the rate of deforestation apparently slowed in the 1980s because the remaining forests became much less accessible. 1990. Indigenous logging methods emphasize repeated extraction of small amounts of timber and other forest products. In addition to the three basic classes of soils, the immense and localized variations in rainfall patterns because of the diverse topography of the Philippines, and the frequency and severity of damage from catastrophic typhoons affect the sustainable management of upland agricultural systems. The University of the Philippines Population Institute projects that the upland population will grow at a rate of 2.72 to 2.92 percent during the next 25 years, increasing by the year 2015 to a density of 371 persons per km2, which is a high population for sloping marginal lands. Sustainable land use systems research. Only a few NGOs are competent to handle community-based resource management on a large scale.
