MANAGING FORESTS FOR MULTIPLE TRADEOFFS: COMPROMISING ON TIMBER, CARBON AND BIODIVERSITY OBJECTIVES
Provedor de dados: 31
Autores: Krcmar,   Emina; van Kooten,   G. Cornelis; Vertinsky,   Ilan.
In this paper, we develop a multiple objective, decision-making model that focuses on forest policies that simultaneously achieve carbon uptake and maintenance of ecosystem diversity objectives. Two forest carbon measures are used - a nominal (undiscounted) net carbon uptake as a proxy for long-term carbon sequestration and discounted net carbon uptake that captures the "fast" carbon accumulation aspect. Ecosystem diversity is expressed in terms of desired structures for forest and afforested agricultural land. Economic effects of possible strategies are examined by comparing attainment of these objectives with the net discounted returns from commercial timber harvests and agricultural activities. The tradeoffs between timber and non-timber objectives are...

Waterfowl Harvest Benefits in Northern Aboriginal Communities and Potential Climate Change Impacts
Provedor de dados: 31
Autores: Krcmar,   Emina; van Kooten,   G. Cornelis; Chan-McLeod,   Ann.
Migratory waterfowl are important to the diets of residents in Canada’s northern communities. Contrary to recreational hunters, indigenous peoples have rights to harvest wildlife for subsistence needs without permits. As a result, migratory waterfowl are an important component of diets of Aboriginal peoples in northern Canada, substituting for expensive beef transported from the south. Wild geese and duck provide many benefits to native people, including improved nutrition and health. In this paper, scaled-down data from global climate models are used in a wildlife model to project potential migratory waterfowl abundance in the Northwest Territories for three future periods up to 2080. The models project potential future harvests of geese and ducks by...

Can Forest Management Strategies Sustain The Development Needs Of The Little Red River Cree First Nation?
Provedor de dados: 31
Autores: Krcmar,   Emina; Nelson,   Harry; van Kooten,   G. Cornelis; Vertinsky,   Ilan; Webb,   Jim.
In this study, we explore whether projected socio-economic needs of the Little Red River Cree Nation (LRRCN) can be met using the natural resources to which they have access. To answer this question, we employ a dynamic optimization model to assess the capacity of the available forest base to provide for anticipated future needs of the LRRCN. Results for alternative management strategies indicate that decision-makers face significant tradeoffs in deciding an appropriate management strategy for the forestlands they control.

MODELING ALTERNATIVE ZONING STRATEGIES IN FOREST MANAGEMENT
Provedor de dados: 31
Autores: Krcmar,   Emina; Vertinsky,   Ilan; van Kooten,   G. Cornelis.
To satisfy public demands for environmental values, forest companies face the prospect of reduced wood supply and increased costs. Some Canadian provincial governments have proposed intensifying silviculture in special zones dedicated to timber production as the means for pushing out the forest possibilities frontier. In this paper, we compare the traditional twozone land allocation framework, which includes ecological reserves and integrated forest management zones, with the triad (three-zone) scheme that adds a zone dedicated to intensive timber production. We compare the solutions of mixed-integer linear programs formulated under both land allocation frameworks and, through sensitivity analysis, explore the conditions under which the triad regime can...

Optimal Forest Strategies for Addressing Tradeoffs and Uncertainty in Economic Development under Old-Growth Constraints
Provedor de dados: 31
Autores: Krcmar,   Emina; Eagle,   Alison J.; van Kooten,   G. Cornelis.
In Canada, governments have historically promoted economic development in rural regions by promoting exploitation of natural resources, particularly forests. Forest resources are an economic development driver in many of the more than 80% of native communities located in forest regions. But forests also provide aboriginal people with cultural and spiritual values, and non-timber forest amenities (e.g., biodiversity, wildlife harvests for meat and fur, etc.), that are incompatible with timber exploitation. Some cultural and other amenities can only be satisfied by maintaining a certain amount of timber in an old-growth state. In that case, resource constraints might be too onerous to satisfy development needs. We employ compromise programming and fuzzy...

Forest Management Zone Design with a Tabu Search Algorithm
Provedor de dados: 31
Autores: Krcmar,   Emina; Mitrovic-Minic,   Snezana; van Kooten,   G. Cornelis; Vertinsky,   Ilan.
Increased conflicts between timber production and environmental protection led some analysts to advocate land-use segregation, often referred to as forest management zoning. The objective of zoning is to create ecologically desirable non-fragmented forest reserves and group timber production areas. We formulate an integer programming model of forest zoning that explicitly addresses clustering of spatial units allocated to timber production and reserve zones while also promoting separation of these zones. A tabu search algorithm is developed, implemented and tested using a case study. The case study results indicate that up to 5% of the net financial return is sacrificed with a 'satisfactory' grouping of units within each zone. A 'good' separation between...
