Forestry Sector Outlook Studies -  GFSS/WP/01 The FAO Global Fibre Supply Study - Assumptions, Methods, Models and Definitions GLOBAL FIBRE SUPPLY STUDY - Working Paper Series
	Bull, G., Scharpenberg, R. and Mabee, W. (1998), EN , 65pp
In late 1995 at the request of the Advisory Committee on Paper and Wood Products the FAO Forestry Department initiated the Global Fibre Supply Study (GFSS) with an outlook to 2010 and beyond. The forest industry community and the public raise the question: Where is the raw material going to come from to cover our forest products needs? To help address this question, the overall study goal has been to "contribute to the world-wide forest policy development through the provision of reliable data, information and analysis of industrial fibre sources". The purpose of this particular working paper is to describe the assumptions, methods, model development and definitions used for the GFSS. It is intended to serve as a guide to the technical underpinnings of the study. It is probably most useful to analysts who wish to understand the details of our approach and it will also help in the further development and management of the database and provide the essential details for improving the supply models. The study output is also described and it consists of two main components: the forest resource database and a fibre supply model used for examining alternative futures.

	Forestry Sector Outlook Studies -  GFSS/WP/02 Factors Affecting Productivity of Tropical Forest Plantations: Acacia, Eucalypt, Teak, Pine GLOBAL FIBRE SUPPLY STUDY - Working Paper Series
	Klara Vichnevetskaia (1997), EN , 60pp
Gains from a good tree improvement program (starting with species/provenance matching to site) can usually result in considerable gain in wood yields from tropical forest plantations. Optimal nursery and silvicultural practices (including seed pre-treatment, application of nitrogen-fixing soil micro-organisms, optimal spacing for defined end use, selection of adequate site, fertilization, and irrigation) can considerably increase such gains further. This report summarizes literature on gains that might be expected by implementing tree improvements and optimal silvicultural practices for acacias, eucalypts, teak and pines in tropical areas. Results are presented for each genus in turn, first examining factors common to all the genera, and then focusing on unique factors. The data on tree-growth gains are extremely variable from study to study. They range from virtually no favourable response to tree improvement and optimal silviculture, to gains of many hundreds of percent over controls. This of course complicates the matter of using such data in global fibre supply modelling.

	Forestry Sector Outlook Studies -  GFSS/WP/03 Implications of Sustainable Forest Management for Global Fibre Supply GLOBAL FIBRE SUPPLY STUDY - Working Paper Series
	Williams, J., Duinker, P., Bull, G. (1997), EN , 44pp
The application of sustainable forest management will have a cost and volume impact on the wood-supply. This study examines the evidence presented thus far in the academic literature, case-studies and field projects. For the purposes of the literature review under the related topics of biodiversity conservation and wood certification is also examined. The initial impacts in terms of harvest volume, at least in the short term ranges between 5 and 25 percent. However, the expectation is that the longer run supply will increase through its wider application. Few studies, journals or field projects report the cost impacts but preliminary evidence suggests that they are expected to rise.

	Forestry Sector Outlook Studies -  GFSS/WP/04 Recovered and Non-wood Fibre: Effects of Alternative Fibres on Global Fibre Supply GLOBAL FIBRE SUPPLY STUDY - Working Paper Series
	Mabee, W.E., Pande, H. (1997), EN , 26pp
The paper examines the impact that alternative fibres, specifically recovered (recycled) and non-wood fibres, have had and may have on the global fibre supply. The properties and availability of each type of fibre are discussed. Based on historical data, three scenarios of future fibre supply were created: a projection of historical trends, an optimal model of high use of both types of fibre, and a minimal model of conservative use. A range of future availability of non-wood and recovered fibre could then be constructed. It was found that, in total, non-wood and recovered fibres currently comprise approximately 51 percent of the current levels of paper and paperboard production. The three scenarios predicted that this fraction would range from 50 to 90 percent of the world’s paper production level by 2010. The projection of historical trends shows a slow increase in alternative fibre content, culminating in a level of about 55 percent of total global paper production by 2010.

	Forestry Sector Outlook Studies -  GFSS/WP/05 Modelling Future Availability of Non-coniferous Veneer Logs and Sawlogs in Tropical Forests GLOBAL FIBRE SUPPLY STUDY - Working Paper Series
	Pulkki, R. E. (1997), EN , 55pp
Non-coniferous veneer and sawlogs supply from tropical rainforests will be limited in the future. This paper first reviews an old methodology used to calculate the availability of these logs and then proposes an improved methodology. The improvement was made feasible given the new data now available in the Global Fibre Supply Study. A model was constructed to estimate the future availability of high-quality non-coniferous tropical logs. Two future supply scenarios were developed, one assumed status quo with conventional logging and much reduced logging intensities in future harvests; and the other assumed sustainable harvesting operations through reduced impact logging. Complementing this paper is a working paper synthesizing the literature on logging impacts and reduced impact logging in tropical rainforests (Working Paper No. 6).

Compiling information on forest harvesting intensity is essential to the discussion of sustainable forest management. This paper presents a bibliographic synthesis of important literature on logging impacts and reduced impact logging in tropical forests. The emphasis is on statistics which contribute to the Global Fibre Supply Study such as logging intensities, cutting cycles and harvesting waste, residual stand development and site damage in non-coniferous tropical forests. This review was then used to provide background information for the modelling work explained in Working Paper No. 5 in this series.
