Prerequisites

Subjects / titles of prerequisite courses: Introduction to forest sciences

Main themes

Main concepts:
Forest economics:
- Valuation of forest based on net present value concept knowing the timing of expenditures and revenues;
- Optimization of forest management based on profitability criteria (including the internal rate of return);                      
- Formation of timber prices on the market;
- Estimation of the value of non-market forest goods and services;
Forest engineering:
- Advantages and constraints of logging systems and wood skidding, protection of soils form compaction, wood transportation.

Learning outcomes

At the end of this learning unit, the student is able to :
1	a. Contribution of the activity to the AA referential (AA of the program)     2.1 2.2 2.4 2.5     5.1 5.4 5.5 5.6     6.2 6.5 6.6 6.7          At the end of this course, the student should be able to :     - Identify the main actors in forest economics (wood industry) and explain their respective interdependence and their regional and international role ;     - Calculate the market value of a tree or a stand according to various methods ;     - Calculate the net present value of a tree plantation based on the timing of expenditures and revenues ;     - Briefly describe several methods for assessing non-market values of forests and propose a practical implementation in a particular case ;     - Compare the profitability of different management scenarios (or investments) using appropriate criteria depending on the objectives assigned to the forest;     - Specify how the tax and legal constraints affect the profitability of forestry investments and mention the uncertainties potentially affecting this profitability;     - Estimate the value of a forest ownership or the indemnity associated to a damage caused to the forest based on a brief description of it, write a report justifying how the value was obtained, orally present and defend the report ;     - Contribute to formulation of relevant forest policies in order to answer to social demands for forest good and services;     - Understand the functioning of the international forest regime and of international strategies related to conservation and use of natural resources and be able to interpret factors influencing forest policies;     - Position his/her activity as future manager of natural patrimony in the legislative and institutional framework of Wallonia and the international forest regime;     - Summarize and present main legislative and institutional instruments implemented in Wallonia in the framework of forest policy;     - Exercise critical thinking in order to identify strengths, weaknesses, threats and opportunities associated with these different instruments.

Teaching methods

The lectures are interspersed with small exercises or issues involving the notions previously presented in the course. In addition, students are encouraged to interact with the professors and with external stakeholders.
Regarding forest economics, students have to carry out a project and to make a report and an oral presentation. The objective is to put the students in a situation commonly encountered by foresters.
For the "Forest Engineering" part, 4 hours of seminars will be given by a forestry expert, in the hours reserved for this course on schedule. No excursions are planned but some aspects of this course will be illustrated in the Silviculture and "Tournée forestière" classes.

Evaluation methods

Regarding forest economics, students are evaluated on:
(i) involvement in the course (solving small exercises, interactions with the professor and external stakeholders)
(ii) an expert report for assessing the value of a forest ownership and the oral defense thereof,
(iii) a written examination (theoretical questions + problem solving).
 For the "Forest Engineering" part, the evaluation is carried out on the basis of a 1-hour written examination (theoretical questions and problem solving).
The final score of the exam is calculated based on weighted mean of the scores of both parts (in proportion to the numbers of hours).

Other information

This course is given in French.
