    Agroforestry in homegardens with high diversity of species which play main agro-ecological roles are complex and sustainable land use systems. Efforts are being made across the globe in valuing and protecting the age-old practices of agroforestry on scientific basis in homegardens. This study analysed the scientific basis of households’ practices in agroforestry homegardens in Matara district of Sri Lanka and develop strategies for the promotion of sustainable agroforestry homegardens. Selected households were interviewed measuring their concern using five point Likert scale, and analysed the qualitative data using non-parametric statistics. The study revealed that scientific basis of household practices in agroforestry homegardens are moderate in selection of appropriate trees and plants, and management of trees and plant health care. Households pay little concern on scientific basis in planning and site placement, land preparation and establishment of trees / crops, and implementing proper cultural practices. There is no significant correlation between scientific basis of practices in agroforestry in relation with size of home-gardens, educational level of households, and across the category of their occupations. Resources to use scientific knowledge in practice, and opportunity to improve scientific skills have moderate correlation significantly while availability of scientific information and access to scientific knowledge have significant but low correlation as applying knowledge on scientific basis by the households. The interest to acquire scientific knowledge, and sufficient time to improve scientific knowledge, and other reasons have no significant correlation with scientific basis of household practices. Carefully planned interventions including policy adjustments and effective extension programs for learning and experimenting couple with supportive programs would enhance scientific basis of household practices for agroforestry in homegardens.

    A study on tree species and crops of agroforestry according to ecological geographic map in North Korea

    This study was conducted to analyze the appropriate tree species and crops according to agroforestry target sites in North Korea based on ecological geography and site properties with the purpose of preparation of technical cooperation on agroforestry, one of the main agendas of the Inter-Korean Forest Cooperation Subcommittee. The agroforestry is one of the methods for forest restoration that satisfies both North Korea's fuel and food shortages and the restoration of deforested land and it began in 2003. To this end, the ecological geographic map (13 regions and 4 zones) of North Korea was made by using satellite images with North Korean journals. The target sites for agroforestry was classified according to 18 site conditions depending on 3 site characteristics (soil depth, relative location, slope), and divided as short-term and long-term target sites depend on agroforestry management period. And then, appropriate tree species and crops for agroforestry are selected according to them. By regions within the same zone, tree species and crops were mostly similar, but compared to each zone, they differed. This seems to be because the geographical climatic characteristics reflected in the ecological geographic map vary greatly from zone to zone. Through this, it is expected to provide information that can be more efficiently implemented through analysis of the target sites needed for application of agroforestry and needed for application of agroforestry management and the combination of suitable species and crops.

    Yield prediction model for falcata (paraserianthes falcataria (L.) Nielsen) in falcata-based agroforestry systems in Misamis Oriental, Philippines

    Sustainable adaption of Falcata-based agroforestry systems and improve tree component productivity in Misamis Oriental necessitates derivation of quantitative information on yield. The project was conducted to determine the yield of Falcata planted in agroforestry systems considering various stand characteristics, physiographic characteristics, cultural practice, and pest incidence. A total of 360 rectangular temporary sample plots (1000 m2 or 20 m x 50 m) across 3 cities and 15 municipalities were established. Diagnostic tests, correlation analysis, and multiple regression analysis were used to develop the Falcata yield, prediction model. The result showed that the yield of Falcata under woodlot, boundary planting, alley cropping, multistorey, intercropping, and taungya agroforestry systems can be explained by age, merchantable height, site index, and spacing. The final yield model for Falcata is sqrtVolume (m3) = 0.1841444 - 10.42376*1/SI + 0.0029367*SP + 0.0842593*A + 0.0473169*MH. The newly developed model will serve as a guide in decision-making as to the right time to harvest, appropriate density, a suitable site for the establishment, and the right merchantable height for greater productivity.
