What is Forest Economics?
study of how scarce forest resources are allocated to meet human needs. Not just money, but social, environmental and biological values too.
Forestry land, irrigated agriculture water usage and focal genera
1.2mil (~1%) hectares land, 4.6% water, and Eucalyptus, Pine and Wattle.
Employment and Econimic contribution
150 000 jobs (18% of agri employment)
R69bil to GDP (~1.9%)
Positive trade balance: R8.4bil
16mil tons produces annually
Core economic concepts
scarcity - limited resources vs unlimited wants
opportunity cost - value of next best opportunity
optimization - choosing best use of resources
PPF
Production Possibility Frontier - the graph.
attainability and efficiency
Capital and economic capital visible
value of sum of money at a given time
land, trees, equipment & infrastructure
Income and price dependants, costs and breakeven analysis
Timber volume & timber price
Type of product, price cycle, supply & demand, and quality
Fixed costs & variable costs. Total manufacturing costs / #units manufactured
income = costs
Unique features of Forestry economics
Long investment period
dual nature of trees: factory and product
flexibility in rotation age & product type
high inventory-to-production ratio
at clear-fell recover invested capital + profit
LEV
Land Expectation Value - max price for land to still earn desired return
NPV
Present value - driving force that determines land use when maximised
Cut too early vs cut too late
Loose volume
Product not suitable or mortality
Silvicultural decisions
Planting density, thinning, pruning, fertilization
Balance between cost, quality & volume
Harvesting economics
manual vs mechanised systems
compare fixed and variable costs
optimise for efficiency and profitability
Demand and Supply shifters
income, tastes, population.
input costs, technology, regulations
Positive & Negative Externalities
Pollution from pulp mill & noise
Forests absorb CO2, scenic beauty attracts tourism, biodiversity supporting ecosystem services.
Externalities causing market failures
Externalities cause market failure because their costs/income are not reflected in market prices, which lead to overproduction of harmful goods or underproduction of beneficial ones.
Justifies government intervention to help correct these inefficiencies.
Constraints on growth
Fire loss: ~18k ha lost annually (~R546mil)
Pests and diseases: ~13k ha lost (~R392mil)
Forestry Economic strengths
Opportunities
Small growers and cooperative
ForEcon summary
ForEcon blends ecology, business & policy
Involves long-term thinking & complex trade-offs
Essential for forest management
4 Basics of Forest Management & Basic resources
Planning, organisation, activation/implementation, control.
Man, materials, machines, methods, money & markets (6 Ms)
Forest Management
deals with making decisions, communicating, motivating, coordinating, delegating tasks & implementing corrections/disciplining actions to ensure the sustainability of the forest enterprise in terms of social, economic & environmental impact.
Economic challenges
Breakeven & profit, budget, competitive financial returns
Bio-physical challenges
Land, water, climate, soil
Social challenges
Employment, externalities, neighbours, customers
Technology challenges
Silvicultural & harvesting, data collection, planning processes
Challenges lead to uncertainty
long rotation periods, risks
Managment plans considertations
challenges, uncertainty & creating order
Stragegic planning
long-term (5-10 years)
set vision
define company, products, industry
Tactical planning
shorter-term (3-5 years)
focus on implementing strategies
tied to market forecasting
compartments to be harvested
tied to periodic block
align man & machine requirements
Operational planning
annual operations
which activities happen when
scheduling of activities
matching resources with activities
Steps in harvest planning
Enumeration
Determine current volume
Compartment list
Project total volume at rotation age & thinning
Determine MAI
Standardise areas
Periodic block scheduling
APO from first period block
Management prescriptions
Developing, evaluating & applying prescriptions
Central activity of forestry
Management descisions
Goals of guide management.
Historical processes by which forest developed in area.
Organisation and classification of my forest by its vegetative, physical & developmental charts.
Kinds of alternative management prescriptions to be considered for each strata, parcel or patch
Methods & data to be used to make quantitative projections of growth and yield, several stages, habitat conditions, sedimentation, cost, revenue & other conditions & outcomes
