This article analyses the impact of national, European and global biofuel targets on German food production and land allocation until 2020. The LEITAP General Equilibrium Model simulates the interaction of agricultural and energy markets in response to the envisaged expansion of the biofuel...

Für den politisch gewünschten Ausbau der Nutzung regenerativer Energien wird eine Steigerung der Biogasproduktion insbesondere auf Basis landwirtschaftlicher Reststoffe wie Wirtschaftsdünger als vorteilhaft angesehen. Obwohl dieser Reststoff produktionskostenfrei zur Verfügung steht, erfolgt...

This paper estimates the social-welfare change due to the application of additional fire prevention measures on Mediterranean forests. The discrete choice experiment is applied to elicit the social preferences regarding fire prevention measures in terms of their impact on fire behaviour...

The article describes the landscape planning possibilities for changing of rural zone functions on an example from a problem area in the district of Kaliningrad. During the field season of 2003 the group of landscape-ecological planning of Faculty of Geography and Geoecology, Kalinigrad State...

The success of any groundwater management plan depends on user compliance. There is an intimate relationship between regulatory regimes and pumper perceptions. As well as its enforcement powers, an agency's behavior sends information to users. While enforcement power need not always be used to...

In this paper we analyse the economic impact of alternative water management instruments that allow addressing the problem of non-renewable groundwater pumping in the aquifers of the Guadalentín Valley (southeast Spain). Their impact is assessed using a partial equilibrium mathematical...

Forest managers in developing countries enforce extraction restrictions to limit forest degradation. In response, villagers may displace some of their extraction to other forests, which generates “leakage†of degradation. Managers also implement poverty alleviation projects to...

This paper introduces a spatial bioeconomic model for study of potential cellulosic biomass supply at regional scale. By modeling the profitability of alternative crop production practices, it captures the opportunity cost of replacing current crops by cellulosic biomass crops. The model draws...

Nitrogen leaching from agriculture contributes to contamination of Lake Taupo. Multiple criteria decision making was used to compare fourteen pre-defined farming systems which reduced, or maintained nitrogen losses. Case study participants included three to four each of Maori Incorporation...
