Non-point source pollution is notoriously difficult to assess. A relevant example is ammonia emissions in the Netherlands. Since the mid 1980s the Dutch government has sought to reduce emissions through a wide variety of measures, the effect of which in turn is monitored using modeling...

The climate change in the agricultural sector acting on multiple weather variables at different times of the various crop cycles. In several cases by changing the mean level of variables (rainfall, temperature, etc..), in other cases by changing the distribution of events. This work provides an...

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...

The biological nature of agricultural production processes induce a higher degree of uncertainty surrounding the economic performance of farm enterprises. This has contributed to the development and acceptance of forms of public intervention aimed at reducing income variability that have no...

Promotion of environmental sustainable farming practices is an important policy goal for the whole agricultural sector. However, when the efficiency of production is measured in practice, enhancement of environmental quality such as biodiversity and other environmental amenities does not seem to...

This paper analyses the impact of the 2003 CAP reform (the so-called Fischler Reform) and its interaction with the Nitrate Directive on the sustainability of selected arable farming systems in a French region (Midi-Pyrénées). The Nitrate Directive is one of the oldest EU environmental programs...

This research analyses the impacts of a scientific advance that improves animal welfare, upon the environment and trade in Scotland using partial equilibrium (PE) modelling. The science improves pig neonatal survival through improved (high fibre) sow diets used before mating. Our model simulates...

Understanding what influences farmers’ decisions to participate in a voluntary agri-environmental scheme(AES) is essential for gauging scheme success. The Rural Environment Protection Scheme (REPS) was a voluntary AES that was available to all Irish farmers from 1994 to 2009. This paper models...

Evaluations of environmental impacts of RDPs are characterized by a number of methodological challenges. However, recent methodological developments have improved the understanding and capacity of analysing the impacts of farming and forestry on the provision of public goods. Against this...

Productive efficiency analysis is a relevant tool that can be used to evaluate differences in efficiency performance between conventional and organic farms. Such study is important for the assessment of the economic viability of these two agricultural systems. While the existing research has...
