The optimal harvesting of a natural resource with seasonal growth O L A F L A A T E N / University of Troms0 Abstract.
This article examines some aspects of the harvesting of a natural resource with a time dependent seasonal growth pattern. optimal harvesting of a natural resource with seasonal growth book Such growth is frequently observed in lower level species.
Ola Flaaten, "The Optimal Harvesting of a Natural Resource with Seasonal Growth," Canadian Journal of Economics, Canadian Economics Association, vol. 16(3. Most harvest theory is based on an assumption of a constant or stochastic environment, yet most populations experience some form of environmental seasonality.
Assuming that a population follows logistic growth we investigate harvesting in seasonal environments, focusing on maximum annual yield (M.A.Y.) and population persistence under five commonly used harvest by: Arrow, K.J.

Optimal Harvesting of a Spatial Renewable Resource Stefan Behringer∗ Thorsten Upmann† Janu Abstract In this paper we investigate the optimal harvesting of a renewable natural resource.
While in most standard approaches the resource is located at a single point, we allow the resource to be distributed spatially. Introduction. The economics of the optimal harvesting of renewable resources is well established. The fundamental papers for the case of fisheries by both Gordon () and Scott () are almost 60 years old by now.
Whereas the former pointed to the problem of overexploitation due to the absence of property rights at sea, the latter established the path of sophisticated dynamic modelling Cited by: Optimal Dynamic Harvest of a Mobile Renewable Resource Article in Natural Resource Modeling 22(2) - May with 36 Reads How we measure 'reads'.
Optimal Harvesting Under Resource Stock and Price Uncertainty* Abstract We analyze optimal harvesting policy and its determinants in a general framework with both stochastic price and stock dynamics.
We state a set of weak conditions under which the optimal harvesting policy can be characterized by a single harvesting threshold and. Optimal Harvesting of Farmed Fish w(t) is equal to the weight when the fish is released, w(0), plus growth until time t.
Specifications of weight functions will be given in the empirical section below. 4 Natural Resource Use. Optimal harvesting of a natural resource with seasonal growth book production from fossil and biological feedstocks is resource intensive, and algal biofuels require resource inputs in the form of water, energy, land, and biofuels have been produced at small scale, sufficient to prove that there are a.
Integrodifference equations are discrete in time and continuous in space, and are used to model the spread of populations that are growing in discrete generations, or at discrete times, and dispersing spatially.
We investigate optimal harvesting strategies, in order to maximize the profit and minimize the cost of harvesting. Theoretical results on the existence, uniqueness and characterization Cited by: 5. This paper develops a two-sector model for a renewable natural resource based economy.
Pareto efficient results show the optimal harvesting rate that allows for sustained long-run optimal growth, which is upper-bounded by the biological rate of reproduction. Regulation prevents from resource over-exploitation and exhaustion.
Among the most important concerns in population ecology is the effect of harvesting a natural population. Harvesting can represent reduction of the population due to hunting or capturing individuals, which in effect removes individuals from the population (Edwards & Penney, ).We can incorporate a percentage harvesting term by subtracting hP from our logistic equation (Giordano et al., ).
OPTIMAL CYCLIC HARVESTING OF RENEWABLE RESOURCE where v 1 (x) and v 2 (x) are lower and upper bounds, respectively, and v 1 (x) ≥ v 0 > 0. All measurable pairs (u, v) satisfying (1) are con-sidered as admissible controls.
Given an admissible velocity control function v, the time needed to the harvester to make one round can be represented as. NATURAL RESOURCE MANAGEMENT FOR SUSTAINABLE GROWTH his edited volume is a product of the ASEAN-Canada Research Partnership, a project supported by the International Development and Research Centre (IDRC), and jointly organised by the S.
Rajaratnam School of International Studies, Nanyang Technological University, and the Institute. A renewable natural resource replenishes itself at a natural rate and can often be harvested at moderate levels for economic or social purposes without damaging its regrowth.
Since heavy harvesting may overwhelm and destroy the population, economics and conservation are crucial ingredients in formulating proper harvesting policies. This represents the productive use of a natural resource. false. The emergence of a meadow in a recently burned forest represents a resilience mechanism.
true. In general, the optimal population for harvesting the maximum sustainable yield is at about 90% of the carrying capacity of the population the grasshopper population exhibits. Why is collaboration in natural resource management so difficult.
This book grapples with those questions. Case studies analyze specific natural resource conflicts in 10 countries and the interventions of people close to the conflicts (in some cases, the authors themselves).Cited by: A solid economic foundation will be critical for achieving the post agenda.
Pathways will include the structural transformation of economies (which will involve decoupling natural resource use and environmental impacts from economic growth) and support for employment (especially where accompanied by rising labour productivity and decent work).
natural resource dependence and economic growth. Section 3 provides a brief overview of recent literature on the subject. In Section 4, we compare the experience of Norway, the world’s most successful oil exporter, with that of other oil-producing countries. In. This book is the result of many years’ experience of teaching fisheries economics and management, also called bioeconomics, for undergraduate and graduate students in interdisciplinary programs, both in Norway and abroad.
These students often have a limited background in economics and mathematics and the challenge has been to be. primary activities involving the subsistence or commercial harvesting of renewable natural resources of land or water.

This is because renew-able resources will be optimally extracted to their maximum yield at which the extraction rate is equal to the natural growth of resources resulting in a zero growth of resources at by: The study of planktonic ecosystems is important as they make up the bottom trophic levels of aquatic food webs.
We study a closed nutrient-phytoplankton-zooplankton (NPZ) model that includes size structure in the juvenile zooplankton. The closed nature of the system allows the formulation of a conservation law of biomass that governs the by: Natural Resources and Growth We consider a model that replaces K, reproducible capital, with Z, an exhaustible resource, in our standard OG model.
The consumer’s problem is essentially the same as in the standard model. Even though Z is a very different thing from K from the point of view of firms who use.

Institutions, economic growth, and the “curse” of natural resources / 1 / Fraser Institute Executive summary The impact of natural resources on economic growth has been a subject of intense debate over the past couple of decades. At the heart of the debate is. • Harvesting does not involve a regular cut of incremental growth.

This is a % decrease from levels, whenha were harvested, and is well below the average area harvested each year during the peak period of to (1 million ha).
The decline is largely due to a decrease in the area of public forest land harvested, primarily in British Columbia as harvesting was reduced in mountain pine. In this paper, based on a pure death process, a practical stochastic control model for population dynamics of released P.
