Die Etablierung des Westlichen Maiswurzelbohrers (Diabrotica virgifera virgifera) stellt eine zentrale Herausforderung für die österreichische Maisproduktion dar. Eine aktive Regulierung ist unerlässlich, um weitere Schäden zu verhindern bzw. zu reduzieren. Die Umsetzung bzw. Nicht-Umsetzung...

In this paper, we conduct a number of cost-benefit analyses to clarify whether the establishment of invasive species should be prevented or the damage of such species should be mitigated after introduction. We use the potential establishment of ragweed in Denmark as an empirical case. The main...

In many parts of the world, irrigation and groundwater consumption are largely dependent on groundwater. Minimizing the adverse effects of water scarcity requires optimal as well as sustainable groundwater management. A common recommendation is to limit groundwater extraction to maximum...

Efficient management of groundwater resource systems requires careful consideration of relationships — both positive and negative — with the surrounding environment. The removal of and protection against “bad” and "ugly" natural capital such as invasive plants and feral animals and the...

In the present paper we describe an e-monitoring location-aware system, based on a real-time Wireless Multimedia Sensor Network (WMSN), integrated with a semi-automatic trapping and insect counting, based on existing traps, able to acquire and transmit data to a remote server, and a Decision...

Invasive alien species cause different types of costs and often need to be controlled. Given several available control measures, choosing the most profitable one is not straightforward, especially if one has no training in economic methodologies. This paper introduces a guidance to assist in...

This paper investigates the impact of heterogeneous intensity in the optimal control of invasive species. By simulating a spatial dynamic optimal control model with eradication and suppression decision variables we find that the intensity of an invasion, as well as the carrying capacity of the...

The issue of timing and scope of policies to manage invasive species has achieved considerable attention in the economic literature. Whereas many earlier studies compare prevention and control for a single invading species, we focus instead on the optimal balance of adaptation and control when...

The invasion by the spreading species is one of the most serious threats to biodiversity and ecosystem functioning. Despite a number of empirical and theoretical studies, there is still no general model about why or when settlement becomes invasion. The purpose of this work is to test a model of...

Eurasian water-milfoil is an aquatic invasive plant that has moved rapidly through lakes across the United States. Along with being a hazard to local ecosystems, water-milfoil is a nuisance to those who use lakes for recreation, and its presence even lowers the value of lakefront properties....

Invasive species pose an enormous threat in the Pacific: not only do they strongly affect biodiversity, but they also potentially affect the economic, social, and cultural wellbeing of Pacific peoples. Invasive species can potentially be managed and their impacts can potentially be avoided,...

Since 2000, approximately $50 million per year has been spent to control infestations of the Glassy-Winged Sharpshooter (GWSS), an insect that spreads Pierce’s Disease (PD). This amount includes the costs of state and federal efforts to monitor and control the GWSS, research on PD/GWSS,...

The invasion by the spreading species is one of the most serious threats to biodiversity and ecosystem functioning. Despite a number of empirical and theoretical studies, there is still no general model about why or when settlement becomes invasion. The purpose of this work is to test a model of...

Harmful non-indigenous species (NIS) impose great economic and environmental impacts globally, but little is known about their impacts in Southeast Asia. Lack of knowledge of the magnitude of the problem hinders the allocation of appropriate resources for NIS prevention and management. We used...

Homegrown value-auction experiments are useful for exploring preferences for controversial product attributes. These auctions have emphasized estimating the effect of the attribute on the willingness to pay (WTP) for a product. The likelihood that individuals are willing to purchase any products...
