THE FAO PRECAUTIONARY APPROACH AFTER ALMOST 10 YEARS: HAVE WE PROGRESSED TOWARDS IMPLEMENTING SIMULATION-TESTED FEEDBACK-CONTROL MANAGEMENT SYSTEMS FOR FISHERIES MANAGEMENT?
Natural Resource Modelling - Tập 19 Số 4 - Trang 441-464
ECONOMICALLY OPTIMAL MARINE RESERVES WITHOUT SPATIAL HETEROGENEITY IN A SIMPLE TWO‐PATCH MODEL
Natural Resource Modelling - Tập 28 Số 3 - Trang 244-255 - 2015
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 economically optimal even when the
system...
MISSED OPPORTUNITIES IN NATURAL RESOURCE MANAGEMENT
Natural Resource Modelling - Tập 8 Số 2 - Trang 111-117 - 1994
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 the reso...
ENDANGERED SPECIES AND NATURAL RESOURCE EXPLOITATION: EXTINCTION VS. COEXISTENCE
Natural Resource Modelling - Tập 8 Số 4 - Trang 389-413 - 1994
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' extinc...
OPTIMAL INVESTMENT IN THE PROTECTION OF A VULNERABLE BIOLOGICAL RESOURCE
Natural Resource Modelling - Tập 3 Số 4 - Trang 463-480 - 1989
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
subject to dim...
MATHEMATICAL MODELING OF DROUGHT RESILIENCE IN AGRICULTURE
Natural Resource Modelling - Tập 26 Số 2 - Trang 237-258 - 2013
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 distinction is being made here between
consecutive droug...
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
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. Costs included capital
investmen...
A LMDI decomposition analysis of carbon dioxide emissions from the electric power sector in Northwest China
Natural Resource Modelling - Tập 33 Số 4 - 2020
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 decomposition method are applied to Northwest
China from 1998...
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
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 ecosystem scale dynamics. We
use a ...
DYNAMICS OF SPATIAL EXPLOITATION: A METAPOPULATION APPROACH
Natural Resource Modelling - Tập 14 Số 3 - Trang 391-418 - 2001
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 exploitation. This model
yields a ...
