This book compiles in an innovative approach a synopsis of work performed in natural and plantation forests in the tropics today, its types, its abundance and the related working conditions. It covers activities of formally and informally employed as well as of self-employed and own-account small-scale forest users, in subsistence and market economy. This includes also the specifics of the substantial work by women and children. The synopsis is widely based on recently published work studies that are centered around the abilities, needs and efforts of the workers while fulfilling their tasks, resulting in performance and workload. Influencing variables from organizational, technical and managerial sides are considered as much as included in the publications. In addition to the mostly studied work in tree harvesting and processing also other activities are analyzed, in manual and motor-manual operations, like on-site conversion by pitsawing, primary transport, planting and pruning. An overview is provided for all interested in work in tropical forests, in particular students and researchers. The work studies described in detail as examples demonstrate the methodical state of the art of ergonomic research. For better understanding of the present orientation and coverage of relevant research a broad background of the development of general work science and forest work science is given. The lasting influence of Taylorism and the role of international agencies, in particular ILO and FAO, are pointed out, as well as the impact of actions by NGOs, e.g. in certification. The book is based on the broad international experience of the author in countries including Indonesia and China, over many years, and his activities in scientific networks on international level. He was teaching forest work science at university and doing related research, including the supervision of numerous theses, e.g. by Master students and PhD researchers from tropical Africa.

Forest harvesting and transportation operations are essential components of sustainable forestry. Recognition of these important factors was consistent with the theme of the XX IUFRO World Congress, "Caring for the Forest: Research in a Changing World". The Congress was held in Tampere, Finland, in August 1995. As part of the proceedings a forum was provided for discussion of new techniques for planning, implementing and controlling forest operations in ways that promote sustainable management of tropical forests. This volume is the Proceedings of the Symposium organised by IUFRO Subject Group S3.05-00, "Forest Operations in the Tropics". A range of technologies is discussed across a number of regions. A paper by Migunga discusses forest soil compaction in Tanzania, while Cordero and Howard evaluate the use of oxen for logging operations in Costa Rica. Rubini Atmawidjaja addresses the management of ecosystems in Indonesia to balance human and environmental needs. Elias studies forest harvesting damages in East Kalimantan while Aulerich reviews the application of skyline systems by one Indonesian company. Shi Mingzhang presents the forest management accomplishments of the Leizhou Forestry Bureau in Quandong province, southern China. A Mexican case study of damage evaluation in a timber yarding operation is presented by Hernández-Diáz and Delgado-Pacheco while the situation for forest operations in the Amazon Basin is reviewed by Malinovski. Cedergren et al. assess the impacts of selective logging on silvicultural values in a mixed dipterocarp forest of Sabah.

Principles of Tropical Horticulture leads the reader through a background of environmental influences and plant physiology to an understanding of production and post-harvest systems, environmental adaptation techniques and marketing strategies. Focusing on the principles behind production practices and their scientific basis, rather than detailed biological traits of each crop, this text outlines successes and failures in practices to date and sets out how the quantity and quality of horticultural produce can improve in the future. Case studies are frequently used and chapters cover the production of vegetables, fruit and ornamental crops, including temperate zone crops adapted to grow in the tropics.

Forests, Water and People in the Humid Tropics is a comprehensive review of the hydrological and physiological functioning of tropical rain forests, the environmental impacts of their disturbance and conversion to other land uses, and optimum strategies for managing them. The book brings together leading specialists in such diverse fields as tropical anthropology and human geography, environmental economics, climatology and meteorology, hydrology, geomorphology, plant and aquatic ecology, forestry and conservation agronomy. The editors have supplemented the individual contributions with invaluable overviews of the main sections and provide key pointers for future research. Specialists will find authenticated detail in chapters written by experts on a whole range of people-water-land use issues, managers and practitioners will learn more about the implications of ongoing and planned forest conversion, while scientists and students will appreciate a unique review of the literature.
