The use of analytic hierarchy process to incorporate stakeholder preferences into regional forest planning

Abstract Forest management decisions are often characterised by complexity, irreversibility and uncertainty. Much of the complexity arises from the multiple-use nature of forest goods and services, difficulty in monetary valuation of ecological services and the involvement of numerous stakeholders. Under these circumstances, conventional methods such as cost-benefit analysis are ill-suited to evaluate forest decisions. The Analytic Hierarchy Process (AHP), can be useful in regional forest planing as it can accommodate conflictual, multidimensional, incommensurable and incomparable set of objectives. The objective of this paper is to examine the scope and feasibility of the AHP in incorporating stakeholder preferences into regional forest planning. The Australian Regional Forest Agreement Programme is taken as an illustrative case for the analysis. The results show that the AHP can formalise public participation in decision making and increase the transparency and the credibility of the process.

Soil erosion in developing countries: a socio-economic appraisal

Soil erosion is the single most important environmental degradation problem in the developing world. Despite the plethora of literature that exists on the incidence, causes and impacts of soil erosion, a concrete understanding of this complex problem is lacking. This paper examines the soil erosion problem in developing countries in order to understand the complex inter-relationships between population pressure, poverty and environmental-institutional dynamics. Two recent theoretical developments, namely Boserups theory on population pressure, poverty and soil erosion and Lopezs theory on environmental and institutional dynamics have been reviewed. The analysis reveals that negative impacts of technical change, inappropriate government policies and poor institutions are largely responsible for the continued soil erosion in developing countries. On the other hand, potential for market-based approaches to mitigate the problem is also low due to the negative externalities involved. A deeper appreciation of institutional and environmental dynamics and policy reforms to strengthen weak institutions may help mitigate the problem.

Incorporating stakeholder values into regional forest planning: a value function approach

Forest management involves multiple objectives, multiple stakeholders, complex socio-ecological and political interactions. Public involvement in forest decision making is a challenging task that involves controversies. Various participatory tools such as public consultation forums, public comment processes, opinion polls are used to consult and to obtain inputs from communities. All these methods can provide useful information but they fail to quantify the trade-offs systematically and offer little help in minimizing conflicts. The Australian Regional Forest Agreement (RFA) program was implemented in response to the decades of conflicts and debate between various stakeholder groups and government over the use and management of forest resources. So far, it has not been able to minimize conflicts in the forestry sector, partly due to its poor incorporation and integration of stakeholder values. This paper uses the value functions approach in modelling stakeholder values in regional forest planning. The results of the study indicate that this method can help to incorporate value preferences effectively into the decision making process. It can also increase the transparency and credibility of the forest planning exercises such as RFA process.

Estimating the Economic Value of Mount Buffalo National Park with the Travel Cost and Contingent Valuation Models

The Mount Buffalo National Park is the oldest national park in Victoria, Australia. There has been a rapid increase in the number of visitors to the park during the last decade and park management has been a concern, especially in the light of declining budgetary allocations and potential damage due to the increased visitor numbers. Policy options to increase park revenue remain unclear because of a lack of information on demand parameters and user costs. This study estimates the economic value of the park using the travel cost method (TCM) and the contingent valuation method (CVM). The TCM gives higher consumer surplus (CS) than the CVM. The CS shows that the economic value of the park is high and that there are opportunities to introduce innovative fee schemes to enhance its revenue. Present entry fee systems do not capture the economic value of the park.

Research methodologies for planning ecotourism and nature conservation

Ecotourism is an important niche market in the world tourism industry. It is becoming increasingly popular as an alternative to mass tourism. The emergence of ecotourism was facilitated by the environmental damage associated with mass tourism. Ecotourism is defined in many ways and there is no consensus as to its exact meaning. However, a number of salient elements, such as environmental conservation, maintenance of biodiversity, a satisfying experience for the visitors, study and appreciation of nature and sustainable community development, are included in many definitions. Tourism creates negative environmental externalities in the form of environmental damage. Such adverse effects can have serious implications for the tourism industry because they damage the very natural resource that forms the raw material for ecotourism. Ecotourism ventures should thus be properly planned and implemented and carefully monitored. Proper planning of ecotourism is hampered by the paucity of relevant qualitative and quantitative information. The use of analytical tools such as the Contingent Valuation Method, carrying capacity, decision analysis techniques with which multi-objective and uncertain consequences can be analysed, and other management strategies, such as the Safe Minimum Standard, can be useful in enabling better planning of ecotourism. Ecotourism can thus enhance the opportunities for better management of natural resources while providing a satisfying experience for the visitor.

Sustainable development and environmental accounting: the challenge to the economics and accounting profession

Purpose – The purpose of this paper is to examine the role of natural resources accounting in sustainable development. Natural resource accounting is important because the welfare of a nation measured in terms of gross domestic product (GDP) has several weaknesses. Design/methodology/approach – This paper achieves this objective by identifying the present status, the constraints and the challenges for the economics and accounting professions. Findings – The main weakness of GDP as a measure of development is that it does not take into account damages to environmental resources. However, the improvement of the concept to include environmental resource use is made difficult because of the difficulties of measuring environmental damage. The challenge to the economics and accounting profession is to ensure interdisciplinary collaboration, development of a framework to explicitly include the environment, development of credible valuation procedures for the environment, and inclusion of the various ethical positions advanced by various groups on the value of the environment. Practical implications – Some headway has been made on these issues during the last decade but a major challenge still lies ahead in further improving these approaches so that sustainable development becomes an achievable goal. Originality/value – This paper brings together diverse views and fusing them together providing a future path for research in environmental accounting to achieve sustainable development.

The Economics and Politics of Wilderness Conservation in Australia

Wilderness conservation has a checkered history in Australian politics. Initially, wilderness was protected in national parks, and specific areas or legislation did not exist. In the 1960s, wilderness conservation became an important issue in Australian politics. Pressure from environmental groups and the general public created several conflicts. Several successes were scored by the joint efforts of interest groups, the public, charismatic individuals, the media, and support of governments and politicians. A number of areas were declared wilderness areas and several states now have wilderness protected through legislation. The 1990s have not been as good as the previous decades for wilderness. Large forest areas are still being cleared and bias toward consumptive use of forest by governments is emerging. Clearly, wilderness protection in Australia is intensely political. It is important that interest groups maintain pressure to protect future wilderness. Efforts to obtain national legislation for wilderness and to couch wilderness in terms of other aspects such as biodiversity and ecosystems values may prove necessary.

Assessment of Wilderness Quality Using the Analytic Hierarchy Process

Wilderness is a unique environmental resource that provides a multitude of use and non-use benefits. The use and management of wilderness depend on the assessment of wilderness quality. Current wilderness assessment in Australia is based on two broad criteria, the remoteness and naturalness of the wilderness, determined using geographic information systems. This paper discusses a complementary assessment method using the Analytic Hierarchy Process (AHP). The AHP can be used to incorporate additional criteria, such as social and cultural criteria, to improve the quality of wilderness assessment. It provides a flexible and compatible method for large-scale wilderness assessments with multiple criteria. The weighting factors for the different criteria can be obtained from expert panels and focus groups.

A chaos theory interpretation of community perceptions of Australian forest policy

This paper proposes a methodology for measuring community values towards Australian forest policy using chaos theory. The use of chaos theory within social sciences has been restricted due to chaos-based analysis requiring time-continuous data. Using scale-based data, iconographs are suggested as a method of dynamically representing community values for forestry at a higher phase plane. In addition, the method also provides opportunity for control of chaos by policy makers in altering community attitudes.

Determination of yield and erosion damage functions using subjectively elicited data: application to smallholder tea in Sri Lanka

Tea has been Sri Lanka’s major export earner for several decades. However, soil erosion on tea‐producing land has had considerable on‐site and off‐site effects. This study quantifies soil erosion impacts for smallholder tea farms in Sri Lanka by estimating a yield damage function and an erosion damage function using a subjective elicitation technique. The Mitscherlich‐Spillman type of function was found to yield acceptable results. The study indicates that high rates of soil erosion require earlier adoption of soil conservation measures than do low rates of erosion. Sensitivity analysis shows the optimum year to change to a conservation practice is very sensitive to the discount rate but less sensitive to the cost of production and price of tea.
