Valuation

The above description summarises forest values, but this does not necessarily imply that economic decisions take account of all these values of tropical forests. Economic values derive from markets, and most of the values of tropical forests are not currently marketed. This is one of the main reasons why unsustainable forestry and deforestation remain highly profitable, and why the value of forests is consistently underestimated in national statistics. For example, in Indonesia, official data show that forests contribute 1% to 2% of GDP, whereas the World Bank estimates that the potential value of forests to that economy to be closer to 15% to 20% of GDP (source) .

Several steps are required to ensure that all values of forests are taken into account when economic decisions are taken. One is that a value must be placed on the cost and benefit of each alternative use scenario for the forest, and this information should be fully considered by decision-makers in the choice between alternative actions. Mechanisms should be developed to capture such values (creation of markets). Existing markets, such as the one for timber, should be made more efficient: the prevailing pricing system for standing timber in the form of stumpage and concession fees used in developing countries, often established by government decrees, has led to serious under-valuation of timber and forests. Revenues to forest owners, usually the State, often amount to only 10 - 20% of those achievable under true market conditions . Finally, mechanisms should be developed ensuring that access to these markets and values is equitable and just.

Total economic value is popularly distinguished in the following taxonomy

There are three main types of measure by which forest values can be approximated: direct market prices; indirect market prices or values; and non-market estimates (hypothetical) of value. The first two measures are based on an estimate of exchange values where buyers and sellers exchange goods or services for money or for other goods or services. In the case of indirect market prices, assumptions have to be made regarding proxy market conditions and how buyers and sellers will behave under different circumstances. Non-market values typically estimate the willingness of "buyers" to purchase or pay for specific goods or services under defined hypothetical conditions, but do not attempt to establish the exchange value that might be established between buyers and "sellers". Thus, non-market value estimates (values to users) are not directly comparable with market-based (exchange) values. Many different techniques exist to obtain such non-market values:

Valuation approaches in relation to type of forest goods and services. Source S. Kengen (1997).

Measures Valuation techniques Example
Direct market prices
  • Market surveys, use of statistics
  • Direct observation
  • Experimental markets

Used to value all market goods and services from the forest unless there are market distortions. The most common cases of distortion is when there are imposed minimum prices or ceilings on goods and services (in such cases, indirect market price techniques are used)

Indirect market prices:

Residual values

Use of market prices for final goods and intermediate inputs plus some measure of profit to arrive at residual value

Stumpage value of timber is derived by looking at market prices for finished lumber and subtracting costs from harvesting through processing to lumber sale

Value of production increases as minimum measure of an input

Use of market prices of production increases to provide proxy measure of the value of one or a set of inputs

Increased market value of crop production with a windbreak over what it would have been without a windbreak provides a proxy minimum gross value for the windbreak. Associated costs of the windbreak are then subtracted to arrive at net value
Surrogate prices and replacement or avoided costs

Use of market prices for close substitute as a proxy measure of value for the unpriced good or service being valued. Both are converted to a common denominator (e.g. heating or protection value)

The maximum value of fuelwood in a new market is estimated on the basis of the value of alternative fuels, e.g. kerosene, after adjusting for the calorific value of the two fuels

The maximum value of a watershed management programme focused only on containing sediment in a downstream reservoir is equalled to the alternative market cost of dredging the reservoir of the additional sediment that would occur without the programme

Opportunity cost

Use of market prices for the best alternative foregone provides a measure of the minimum value for a good or service. This is essentially a cost measure used to provide minimum value for a benefit

The minimum value of a wilderness park is estimated on the basis of market priced value of the goods and/or services forgone (e.g. timber, mineral, grazing)
Differences in travel costs as the measure of value of an area, facility or activity

Per caput measures of participation from different distance zones are used to derive estimates of the value of an area, facility or activity

Differences in market-priced costs of trips by different users to a reserve are used to value nature-based tourism on the basis of differences in use rates in relation to differences in trip costs
Non-market value estimates Contingent valuation or surveys of stakeholders' willingness to pay for a given event, area, facility, activity (this is a measure of value in use) Value of a certain wildlife population is inferred from a survey of environmentalists' willingness to pay to save the population

In a paper published in 1997 in Nature by Costanza et al., many of the approaches listed above were put to the task of estimating the value of goods and services provided by ecosystems worldwide. This analysis (which is by default approximate and subject to much criticism) put the economic value of the world's ecosystem services at $33 trillion, compared to the "classical" GNP of $18 trillion. Forests accounted for an annual $4.7 trillion of this amount. Little of this amount goes around in formal markets.

The authors estimated that at least 70% of these values are generated in developing countries.
Many efforts are currently directed at developing mechanisms to capture forest values that are not currently marketed and mechanisms to transfer these values from those willing to pay to those providing the services. This is of particular importance for those forest values, which are mainly benefiting the global community (biodiversity protection, climate regulation), while maintaining these values bears a high opportunity cost for local communities. A large number of mechanisms have been proposed, which are summarised below. Another overview is in ETFRN

Classification of financial incentive mechanisms (Source: Richards, 1999)

Mainly Domestic Mainly International
Transfer Payments Approach

Fiscal market-based instruments (MBIs) and subsidies

‘polluter and beneficiary pays’
taxes;
‘ecological VAT’;
differential land use taxes;
forest pricing (including concession bidding,
performance bonds);
tree planting subsidies

International transfer payments: debt-for-nature swaps

Global Environment Facility;
National Environment Funds or conservation trust funds;
international timber trade taxes;
area-based payments to forest management units;
other international taxes
Market Approaches based on Public Good Benefits carbon offset trading;
fair trade;
certification of forest products;
bioprospecting deals;
Forest Protection and Management Obligations
Private/Public Investment Flows micro-finance to local users channelling private international flows, especially portfolio capital;
multilateral funds to stimulate private investment and public/private financing
Property Rights Approach clarifying existing property rights;
creating community usufruct rights;
tradeable development rights (TDRs);
overlapping property rights;
service concessions
international TDRs, franchise agreements and conservation easements;
intellectual property rights

Many of these proposed mechanisms are in embryonic stage, but much is expected for several of them, particularly carbon trading under the Kyoto protocol.
