FAO. 2007. Forest harvesting case study 23. The impact of timber harvesting on the availability of non-wood forest products in the Congo basin.
This study seeks to examine the impact of timber harvesting in two villages, one in Cameroon and one in the Central African Republic. It documents many plant-based and animal-based NWFPs of great signifi cance to the livelihoods of the local populations in terms of food security, income generation and health.

FAO. 2005. Forest harvesting case study 22. Pitsawn timber production in natural forests of Uganda.
The case study was conducted to highlight the impacts of pitsawing in Uganda and the approach of policy-makers to this industry. This report provides an assessment of current forest management practices, forest policies and laws with regard to pitsawing. The report also analyses the prevailing policies that have indirectly encouraged the emergence of the industry.

FAO. 2005. Forest harvesting case study 21. Chainsawing in the natural forests of Ghana.
Chainsawing in Ghana is a subset of illegal forest activities. Therefore, the report examines the past actions or inaction that have encouraged illegal timber harvesting activities as well as the capacity of the Forestry Commission (FC) to deal with them. Law enforcement and governance are important with regard to the control of illegal forest activities.

FAO. 2005. Forest harvesting case study 20. Forest operation improvements in farm forestry in Slovenia.
Forests in Europe are predominantly privately owned. The average size of private forest estates in Europe amounts to approximately 11 ha, whereby several millions of private forest owners own less than 3 ha of forest property (TBFRA, 2000). Some typical characteristics of owners of small forest estates are: reduced interest for working in forests; inefficient equipment and qualification for work in the forest environment; low profitability and insufficient skills for promoting wood products in the market.

FAO. 2002. Forest harvesting case study 19. Environmentally sound forest harvesting in Brazil.
This study is a follow-up to a previous study in this series (Winkler 1997). Both studies were undertaken in a managed natural forest near Itacoatiara in the Amazon region of Brazil. The two studies were conducted in collaboration with Precious Woods Amazon (PWA). The purpose of this re-examination was to assess the condition of the forest four years after logging had been completed. For this purpose, assessments were undertaken on regeneration within felling gaps and on skid trails, water infiltration rates on skid trails, the current status of potential crop trees and the condition of residual trees of commercial species.

FAO. 2002. Forest harvesting case study 18. Commercial timber harvesting in the natural forests of Mozambique.
The present study analyses five enterprises in northern, central, and southern Mozambique. Efficiency is evaluated by means of operational, organizational, energy, and financial indicators. Operational data were collected through time studies with continuous timing. Costs per machine-hour were calculated with the "Production and Cost Evaluation Programme - PACE" (FAO 1992). Intermediate results on output were then related to those on input, yielding indicators for operational efficiency, organizational efficiency as well as energy and financial efficiency.

FAO. 2002. Forest harvesting case study 17. Financial and economic assessment of timber harvesting operations in Sarawak, Malaysia.
Timber harvesting with tractors is the standard extraction method in the Mixed Hill Dipterocarp Forests of Sarawak, Malaysia. Conventional Logging (CL) systems cause substantial disturbance and damage to forest stands and the environment. This is why over the last few years, Codes of Practice on Reduced Impact Logging (RIL) have been developed and implemented in many trial areas of tropical natural forests. A Cost-Benefit-Analysis (CBA) reported in this study compares the project worth of two timber harvesting systems.

FAO. 2001. Forest harvesting case study 16. Forest harvesting practice in Concessions in Suriname.
The study was carried out in a tropical natural forest of the Guyana Shield in the Forest Belt of Suriname close to Kabo, district of Para. One of the numerous small concession holders serving the local timber market was identified and proved willing to host this study, which required the application of "planned" harvesting on the cooperator's timber concession number 387. The objective was to provide a comprehensive analysis of planned harvesting as an alternative to the conventional way of logging as usually carried out in Suriname.

FAO. 1998. Forest harvesting case study 15. Forest harvesting operations in Papua New Guinea; The PNG Logging Code of Practice.
The study was carried out in tropical natural forest of Sandaun Province and on New Britain Island, both Papua New Guinea (PNG). Two timber permit holders, namely Vanimo Forest Products Pty Ltd. (VFP) and Stettin Bay Lumber Company Ltd. (SBLC), agreed to host this study on forest harvesting operations in Papua New Guinea. The study documents each phase of the forest harvesting system currently applied by the above-mentioned companies and compares planning and implementation of harvesting operations in the field against relevant regulations as published in the Papua New Guinea Logging Code of Practice.

FAO. 1998. Forest harvesting case study 14. Assessment of the Needs for Marketing Training in the Forestry Sector in Chile.
The forest products marketing educational needs of Chile were investigated to determine the current availability of such training and assess marketing areas where strengthening may be needed. The work was a collaboration involving the University of Bío-Bío in Concepción, Chile, the Center for Forest Products Marketing and Management at Virginia Polytechnic Institute, and the Food and Agriculture Organization of the United Nations. Investigators, through secondary research and initial interviews, identified important marketing factors and organizations that were to be included in the study. A data collection instrument was designed and reviewed by the investigation team and sent to key people at the selected organizations prior to personal interviews. Personal interviews with 16 different organizations were conducted.

FAO. 1998. Forest harvesting case study 12. Environmentally sound forest infrastructure development and harvesting in Bhutan.
The study was carried out in natural forests of the Himalayan range in Bhutan in the spring of 1998. The Third Forestry Development Project (TFDP) in Eastern Bhutan was selected to demonstrate that Environmentally Friendly Forest Engineering considerably reduces the effect of damaging elements of forest road construction. The study documents each phase of both environmentally sound road construction by excavators and traditional road construction by bulldozers and compares environmental impacts of both construction techniques.

FAO. 1998. Forest harvesting case study 11. Reduced impact timber harvesting in the tropical natural forest in Indonesia.
The study was carried out in the tropical natural forest, concession area of PT. Sumalindo Lestari Jaya IV in Berau Regency, East Kalimantan, Indonesia.
