Última Can Forest Management Strategies Sustain The Development Needs Of The Little Red River Cree First Nation? AgEcon 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.

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...

Ano: 2005 URL: http://purl.umn.edu/37022 MANAGING FORESTS FOR MULTIPLE TRADEOFFS: COMPROMISING ON TIMBER, CARBON AND BIODIVERSITY OBJECTIVES AgEcon 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... Tipo: Working or Discussion Paper Palavras-chave: Environmental Economics and Policy; Resource /Energy Economics and Policy. Ano: 2004 URL: http://purl.umn.edu/18161 MODELING ALTERNATIVE ZONING STRATEGIES IN FOREST MANAGEMENT AgEcon 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...
