A cycle‐jumping method for multicyclic Hubbert modeling of resource production Nat. Resour. Model. (IF 0.915) Pub Date : 2020-11-25 Bolorchimeg N. Tunnell; James A. Conder; Ken B. Anderson; Marek Locmelis
The amount of ultimately recoverable resources and/or timing of peak production have been the central purpose of numerous studies. One broadly applied method is Hubbert modeling, subsequently extended as multicyclic Hubbert modeling. This paper explores a modification to conventional multicyclic Hubbert modeling that we term “cycle‐jumping” wherein the overlap of multiple curves is limited and explicitly

Contingency firelines can be used to back up primary lines to increase probability of fire containment, decrease fire losses, and improve firefighter safety. In this study, we classify firelines into primary, contingency, and response lines. We design a modeling process to iteratively implement a mixed integer programming model to evaluate contingency strategies under randomly generated fireline breaching

Using Markov chains to quantitatively assess movement patterns of invasive fishes impacted by a carbon dioxide barrier in outdoor ponds Nat. Resour. Model. (IF 0.915) Pub Date : 2020-09-14 Lauren K. Borland; Collin J. Mulcahy; Barbara A. Bennie; Douglas D. Baumann; Roger J. Haro; Molly Van Appledorn; Kathi Jo Jankowski; Aaron R. Cupp; Richard A. Erickson
Natural resource managers use barriers to deter the movement of aquatic invasive species. Research and development of new invasive species barriers is often evaluated in pond and field scales using high‐resolution telemetry data. Telemetry data sets can be a rich source of data about fish movement and behavior but can be difficult to analyze due to the size of these data sets as well as their irregular

Multiobjective record‐to‐record travel metaheuristic method for solving forest supply chain management problems with economic and environmental objectives Nat. Resour. Model. (IF 0.915) Pub Date : 2020-01-24 Ji She; Woodam Chung; Hector Vergara
Multiobjective optimization is increasingly used to assist decision‐making in forest management when multiple objectives are considered and conflict with each other. Since forest management problems may deal with combinatorial optimization, as the scale of a problem increases, the computation complexity increases exponentially beyond the practical use of exact methods.

The influence of lateral flows in an aquifer on the agricultural value of groundwater Nat. Resour. Model. (IF 0.915) Pub Date : 2020-04-13 Kent F. Kovacs, Alvaro Durand‐Morat
Valuation of water in an aquifer depends on reliable information about the hydrologic conditions of an aquifer. Regions of depression emerge in an aquifer because groundwater cannot seamlessly flow between shallow and deep aquifer locations, and our analysis shows that the degree of lateral flow influences the value of the water in the aquifer. The assumption that groundwater declines uniformly over

Common pool resources with support Nat. Resour. Model. (IF 0.915) Pub Date : 2019-11-19 Erik Ansink, Hans‐Peter Weikard
We examine the role of support for coalition stability in common pool resource games such as fisheries games. Some players may not want to join a coalition that jointly manages a resource. Still, because they benefit from spillovers, they may want to support the coalition with a transfer payment to set incentives for others to join. We find that the impact of support on equilibria of this game is limited

A copula‐based index for drought analysis in arid and semi‐arid regions of Iran Nat. Resour. Model. (IF 0.915) Pub Date : 2019-08-08 Ommolbanin Bazrafshan, Hossein Zamani, Marzieh Shekari
The copula functions are frequently used by researchers for modeling dependence structure among the correlated attributes in many areas. The copulas are widely used for the analysis of drought frequency, drought characteristics, drought coincidence risk, uncertainty, and drought forecasting. In this research, we have compared two indices of drought assessment, including SPI‐12 and copula‐based joint

The impact of environmental regulations on forest product trade in China Nat. Resour. Model. (IF 0.915) Pub Date : 2019-07-24 Yijing Zhang, Wen Luo, Xinyun Duan, Lan Gao
Forest product trade plays an important role in the development of the Chinese forest industry. The trading value of forest product has shown a yearly growth rate of 12% during the last five recent years. Stringent environmental regulations in China have a profound impact on raw material supplies and industrial production in the forest sector; however, their impact on the forest product trade is still

Innovation as a policy strategy for natural resource protection Nat. Resour. Model. (IF 0.915) Pub Date : 2019-07-16 Jeffrey M. Peterson
Growing global food demands place major strains on water resources, including quality impairments and increased water scarcity. Drawing on the largely separate bodies of literature on externalities and technological innovation, this article develops a dynamic framework to explore the long‐term impacts of alternative policy approaches to the agricultural impacts on water resources. Environmental policies

Back to the future: A retrospective assessment of model‐based scenarios for the management of the shrimp fishery in French Guiana facing global change Nat. Resour. Model. (IF 0.915) Pub Date : 2019-07-16 Fabian Blanchard, Christian Chaboud, Olivier Thébaud
While the number of models dedicated to predicting the consequences of alternative resource management strategies has increased, instances in which authors look back at past predictions to learn from discrepancies between these and observed developments are scarce. In the past decades, the French Guiana shrimp fishery has experienced shrimp market globalization and decreasing levels of shrimp recruitment
