MATHEMATICAL MODELING OF DROUGHT RESILIENCE IN AGRICULTURE
Natural Resource Modelling - Tập 26 Số 2 - Trang 237-258 - 2013
Ram Ranjan
Abstract.  Ensuring drought resilience for farmers is an important policy concern. Yet, a quantitative treatment of the concept of drought resilience has been lacking in the literature. This paper designs a mathematical model of drought resilience to assess farmers’ survival strategies when faced with the prospect of repeated droughts. A key distin...... hiện toàn bộ
ENDANGERED SPECIES AND NATURAL RESOURCE EXPLOITATION: EXTINCTION VS. COEXISTENCE
Natural Resource Modelling - Tập 8 Số 4 - Trang 389-413 - 1994
Yacov Tsur, Amos Zemel
A model of renewable resource exploitation under event uncertainty is formulated. The model is applied to analyze the situation in which excessive water diversion for human needs can lead to the extinction of an animal population. Special attention is given to uncertainty regarding the conditions that lead to extinction. The manner in which the potential benefit foregone due to the species...... hiện toàn bộ
OPTIMAL INVESTMENT IN THE PROTECTION OF A VULNERABLE BIOLOGICAL RESOURCE
Natural Resource Modelling - Tập 3 Số 4 - Trang 463-480 - 1989
William J. Reed
It is assumed that the probability of destruction of a biological asset by natural hazards can be reduced through investment in protection. Specifically a model, in which the hazard rate depends on both the age of the asset and the accumulated invested protection capital, is assumed. The protection capital depreciates through time and its effectiveness in reducing the hazard rate is subjec...... hiện toàn bộ
THE FAO PRECAUTIONARY APPROACH AFTER ALMOST 10 YEARS: HAVE WE PROGRESSED TOWARDS IMPLEMENTING SIMULATION-TESTED FEEDBACK-CONTROL MANAGEMENT SYSTEMS FOR FISHERIES MANAGEMENT?

ECONOMICALLY OPTIMAL MARINE RESERVES WITHOUT SPATIAL HETEROGENEITY IN A SIMPLE TWO‐PATCH MODEL
Natural Resource Modelling - Tập 28 Số 3 - Trang 244-255 - 2015
Holly V. Moeller, Michael G. Neubert
ABSTRACTBioeconomic analyses of spatial fishery models have established that marine reserves can be economically optimal (i.e., maximize sustainable profit) when there is some type of spatial heterogeneity in the system. Analyses of spatially continuous models and models with more than two discrete patches have also demonstrated that marine reserves can be economic...... hiện toàn bộ
MODELING THE SPATIAL DISTRIBUTION OF THE ECONOMIC COSTS AND BENEFITS OF ILLEGAL GAME MEAT HUNTING IN THE SERENGETI
Natural Resource Modelling - Tập 13 Số 1 - Trang 151-177 - 2000
Heribert Hofer, Kenneth L. Campbell, Marion L. East, S. A Huish
ABSTRACT. Illegal game meat hunting in the Serengeti National Park, Tanzania, and adjacent game reserves provides an important source of protein and cash income to local communities. We construct a profitability model that describes the spatial distribution of the economic costs and benefits of illegal hunting in the Serengeti during the late 1980s and early 1990s. ...... hiện toàn bộ
A LMDI decomposition analysis of carbon dioxide emissions from the electric power sector in Northwest China
Natural Resource Modelling - Tập 33 Số 4 - 2020
Lina Mai, Qiying Ran, Haitao Wu
AbstractTaking advantage of the electrification strategy, Northwest China has made full use of its natural resources endowment, to develop renewable energy as the substitution of thermal power. To evaluate carbon dioxide (CO2) emissions from electric power sector, an extended Kaya identity equation and the Logarithmic mean Divisia index decompo...... hiện toàn bộ
MISSED OPPORTUNITIES IN NATURAL RESOURCE MANAGEMENT
Natural Resource Modelling - Tập 8 Số 2 - Trang 111-117 - 1994
Donald Ludwig
After 20 years of effort, technical approaches to natural resource management have not been effective in preventing overuse and destruction of resources. The resource modeling community can help to change our present course toward destruction by (1) recognizing and publicizing the ineffectiveness of scientific, technical and magical approaches to resource management, (2) pointing out that ...... hiện toàn bộ
A MODEL FOR THE BIOECONOMIC EVALUATION OF MARINE PROTECTED AREA SIZE AND PLACEMENT IN THE NORTH SEA
Natural Resource Modelling - Tập 15 Số 4 - Trang 413-437 - 2002
Alasdair I. Beattie, U. Rashid Sumaila, Villy Christensen, Daniel Pauly
ABSTRACT. The use of marine protected areas (MPAs) as a basic management tool to limit exploitation rates in marine fisheries has been widely suggested. Models are important in predicting the consequences of management decisions and the design of monitoring programs in terms of policy goals. However, few tools are available that consider both multiple fleets and eco...... hiện toàn bộ
DYNAMICS OF SPATIAL EXPLOITATION: A METAPOPULATION APPROACH
Natural Resource Modelling - Tập 14 Số 3 - Trang 391-418 - 2001
James N. Sanchirico, James E. Wilen
ABSTRACT. In this paper we present a bioeconomic model of a harvesting industry operating over a heterogeneous environment comprised of discrete biological populations interconnected by dispersal processes. The model generalizes the Gordon [1954]/Smith [1968] model of open‐access rent dissipation by accounting for intertemporal and spatial “Ricardian” patterns of ex...... hiện toàn bộ
