Abstract Information on the water quality of rivers can be used to judge the effectiveness of
past policies or to guide future environmental policies. Consequently, the location of water …

New Zealand dairy farmers face a tradeoff between profit maximisation and environmental
performance. The integrated simulation model presented here enables assessment of the …

Nitrate transfer from agricultural sources via river networks remains a serious unresolved
and complex issue. This article proposes an economic analysis of the optimal reduction of …

A policy based on the Polluter Pays Principle (PPP) with respect to the subject of
contamination by nitrogen fertilizer is proposed. The mechanism is tested via a cost-efficient …

This research explores the environmental and economic implications of nitrogen discharge
abatement from dairy farms. This thesis develops a framework to analyse agri-environmental …

The use of riparian land buffers is widely promoted as a method of mitigating the effects of
sediment and nutrient runoff from intensive land use in New Zealand. Farmers receive …

In spite of references to agricultural externalities that usually focus more on the negative
impacts of agricultural inputs on the environment, the inclusion of preferred benefit …

The main purpose of this study was to evaluate the effect of alternative cropping systems on
farm net returns, and nitrate-N and sediment yields in Thomas Brook Watershed (TBW). The …

Overuse of fertilizers can have harmful effects on the environment. The Nitrates Directive
aims to protect water quality by preventing nitrates from agricultural sources polluting ground …

This paper proposes, for different water scarcity conditions, a cost efficient input tax policy to
supply clean drinking water that is subject to contamination by nitrogen fertiliser and to …
