Poaching and the Protection of an Endangered Species : a Game - Theoretic Approach - Draft
نویسندگان
چکیده
The poaching of endangered species like the elephant and the rhino has increased dramatically over the last decade. Antipoaching patrols must use their limited resources strategically in order to achieve the highest level of protection. We develop a model that views poaching and protection as a repeated game between strategic players. We conceptualize a “space” within which an endangered species is distributed spatially and temporally through migration. Poaching and anti-poaching patrolling are introduced as spatial-temporal activities in the space. We study the long-term effects of different strategies of a poaching unit and an anti-poaching unit on the population dynamics of an endangered species. We solve for a mixed strategy Nash equilibrium in this game and provide a proof for it uniqueness. The model is generally applicable to the protection of spatially distributed species populations that are subject to illegal harvest.

Adaptive resource allocation for wildlife protection against illegal poachers
Illegal poaching is an international problem that leads to the extinction of species and the destruction of ecosystems. As evidenced by dangerously dwindling populations of endangered species, existing anti-poaching mechanisms are insufficient. This paper introduces the Protection Assistant for Wildlife Security (PAWS) application a joint deployment effort done with researchers at Uganda’s Quee...

In this study, the social welfare impacts of the interaction of Iranian rice import policies and Thai export policies are analyzed using a game theoretic approach in conjunction with econometric supply and demand models. The joint impacts of increasing the world price of rice, resulting from the export policies in Thailand along with changes in tariff rates in Iran, on social welfare are analyz...
متن کاملDeploying PAWS: Field Optimization of the Protection Assistant for Wildlife Security
Poaching is a serious threat to the conservation of key species and whole ecosystems. While conducting foot patrols is the most commonly used approach in many countries to prevent poaching, such patrols often do not make the best use of limited patrolling resources. To remedy this situation, prior work introduced a novel emerging application called PAWS (Protection Assistant for Wildlife Securi...

Intensified industrialization in developing countries has recently resulted in huge electric power demand growth; however, electricity generation in these countries is still heavily reliant on inefficient and traditional non-renewable technologies. In this paper, we develop an integrated game-theoretic model for effective power systems planning thorough balancing between supply and demand for e...
متن کاملGame-Theoretic Approach for Pricing Decisions in Dual-Channel Supply Chain
In the current study, a dual-channel supply chain is considered containing one manufacturer and two retailers. It is assumed that the manufacturer and retailers have the same decision powers. A game-theoretic approach is developed to analyze pricing decisions under the centralized and decentralized scenarios. First, the Nash model is established to obtain the equilibrium decisions in the decent...
