Based on thorough bibliographic research of a highly controversial topic, this report, jointly sponsored by IUCN, UNEP and WWF, shows the potential of plantations, while also exposing problems which may arise if massive tree plantations proposed for the tropics are to be established. Major issues covered include; species selection, soil and water cycle effects, fires, pests and diseases, effects on biodiversity, carbon dioxide fixation, land tenure and social issues, and plantation economics. Some broad conclusions and guidelines to be considered when establishing large scale plantations in the tropics complete this study.

Soil Fertility Decline in the Tropics available in PDF, EPUB and Kindle. Wide coverage of soils and perennial cropping systems in the tropicsSynthesis of decades of researchChallenges assumptions on the benefits of plantations for soil fertilityIt is generally assumed that soil fertility decline is widespread in the tropics and that this is largely associated with annual cropping and subsistence farming. In contrast, perennial plant cover (as in plantation agriculture) provides better protection for the soil.This book reviews these concepts, focusing on soil chemical changes under different land-use systems in the tropics. These include perennial crops, annual crops and forest plantations. Two case studies, on sisal plantations in Tanzania and sugar cane in Papua New Guinea, are presented for detailed analysis. The author demonstrates that soil fertility decline is also a problem on plantations.

This new edition has been completely revised to provide up-to-date accounts of silvicultural practices, rural development issues, and the wider role that tree-planting plays. The chapters on agroforestry and protection forestry have been virutally rewritten, while throughout the book theimportant place of social forestry is recognized.

Download and read online ebook Plantation Technology in Tropical Forest Science write by K. Suzuki. This book was released on 2006-06-18. Plantation Technology in Tropical Forest Science available in PDF, EPUB and Kindle. This book is intended to be a record of the Biotechnology-Assisted Re/Afforestation Project in the Asia-Pacific Region (BIO-REFOR) since 1992, conducted in coop eration with the International Union of Forest Research Organizations (lUFRO). The purpose of the project is to promote exchanges of information of fundamental research on indigenous species in the Asia-Pacific Region in order to restore natural forests. The production, cultivation, and maintenance of forest tree species provide highly sustainable production systems that conserve soils, the microenvironment, and biodiversity The key technology for biomass production of forests is propagation via micropropagation or traditional propagation. However, there are many recalci trant species among useful forest trees to be propagated in large numbers. Recent advances in mycorrhizal technology and in vitro culture have made it possible to commercially propagate useful trees for re/afforestation. In this book, comprehensive information is provided on propagation, mycor rhizal inoculation, and reforestation of economically and environmentally impor tant forest trees, information that usually is available only in widely scattered re sources. Here, we include a wide area of the ecology and physiology of dipterocarps as a general overview, and then cover propagation techniques, mycorrhizal symbio sis, man-made forests, and biodiversity in the Asia-Pacific region.
