With a mandate, U.S. policy of ethanol tax credits designed to reduce oil consumption does the exact opposite. A tax credit is a direct gasoline consumption subsidy with no effect on the ethanol price and therefore does not help either corn or ethanol producers. To understand this, consider...

Perceptions of a salinity ‘crisis’ in Australia around 2000 resulted in the establishment of a major national program that aimed to prevent, stabilize, and reverse trends in salinity. The National Action Plan for Salinity and Water Quality allocated A$1.4 billion of public funds to 1700...

Water is increasingly being treated as a tradable commodity. This paper describes our efforts to include water accounts in a multi-regional CGE model. In order to understand the conditions under which water trade might occur, we need to add a number of features to the model and scenarios. These...

Appropriate management and policy responses for dryland salinity vary depending on biophysical and socio-economic conditions, and on the resources in question (water resources, biodiversity, infrastructure, agricultural land, salt-affected land). In this paper we present a framework for...

Environmental agencies and utilities wishing to support environmental projects face the challenge of deciding which of the many possible projects they should support with their limited resources. Projects vary greatly in their benefits and costs, so selecting the best projects can make a major...

Mára széles körűen elfogadott tény, hogy az emberi tevékenységek – mint a szén, az olaj vagy a gáz elégetése – során keletkező üvegházhatású gázok kibocsátása általános felmelegedést okoz a Föld légkörében. Az elmúlt évtizedekben egyre világosabban...

Since the late 1980s, the concept of precaution has been incorporated into numerous international agreements and laws, as well as in domestic statutes and policies in many countries. This paper examines the international emergence of the concept and its application in Australia. Despite rapid...

Metrics for evaluating environmental trade-offs can be developed with varying levels of consistency across case study sites. A key issue is whether standard evaluation experiments can be conducted over multiple sites, or whether experiments have to be tailored to each case study application. To...

Mathematical programming models suit policy makers' needs for assessing impacts of new policies and modellers' needs for new parameters, constraints and activities to represent the phenomenon under study. The AROPAj model aims at taking into account any geographical extension of the European...

This paper analyzes the links between agriculture and tourism. A contingent valuation study assesses tourist's willingness to pay (WTP) for agro-tourism and agriculture's positive environmental services and related positive externalities. The paper analyzes factors influencing tourist...
