| Growth, metabolic rate, and energy reserves of Cherax quadricarinatus (von Martens, 1868) juveniles were evaluated in crayfish acclimated for 16 weeks to either 25ºC (temperature near optimum) or 20ºC (marginal for the species). Additionally, the modulating effect of ecdsyone on acclimation was studied. After 12 weeks of exposure, weight gain of both experimental groups acclimated to 25ºC (control: C25, and ecdysone treated: E25) was significantly higher than that of those groups acclimated to 20ºC (C20 and E20). A total compensation in metabolic rate was seen after acclimation from 25ºC to 20ºC; for both the control group and the group treated with ecdysone. A Q10value significantly higher was only observed in the group acclimated to 20ºC and treated with... |

| The effects of the 2003 CAP reform on the farmers’ decisions on whether to abandon their farming activity, how much to produce and what to produce are analyzed in the present paper. To this effect data collected for Hungarian, Dutch and Greek farmers on their perceptions about the reform and its effects, and on their production intentions is analyzed using discrete choice models under 3 alternative scenarios for the future produce prices. The discrete choice model applied in the present paper is sequential since farmers are confronted with a sequence of choices. In the first stage, the choice is between abandoning farming or continuing, then those farmers who have chosen to continue are presented with two additional choices related to their level of... |

| A major problem being faced by human society is that the global temperature is believed to be rising due to human activity that releases carbon dioxide to the atmosphere; i.e., global warming. The major culprit is thought to be fossil fuel burning, which is releasing increasing amounts of carbon dioxide in the atmosphere. The problem of increasing atmospheric carbon dioxide can be addressed a number of ways. One of these is forestry and forest management. This paper examines a number of current issues related to mitigating the global warming problem through forestry. First, the overall carbon cycle is described, and the potential impact of forests on the buildup of atmospheric carbon is examined. A major focus is the means by which forests and forest... |

| The reform of the CAP in 1999, with extensive revisions in 2003 (Council regulation 1782/2003), was constructed around three central ideas: decoupling, cross-compliance of payments, and modulation. Decoupling, which is specifically analysed in this article, is intended to eliminate all aid linked in one way or another to production, in favour of aid which is completely independent of the production activity. It is encapsulated in the new 2003 regulation by the introduction of the right to a single farm payment (SFP) proportional to farm area, independent of production activities. These new arrangements have been accompanied by much variation in the application of the reform, and the member states have taken great advantage of the extensive room for... |

| Whether economic growth can be sustained in a finite natural world is one of the earliest and most enduring questions in economic literature. Even with unprecedented growth in human population and resource consumption, humans have been quite adept at finding solutions to the problem of scarce natural resources, particularly in response to signals of increased scarcity. Because environmental resources generally are not generally traded on markets, however, scarcity signals for these resources may be inadequate, and appropriate policy responses are difficult to implement and manage. In the debate over the economic scarcity of natural resources, one significant change in recent years has been a greater focus on the ecosystem services and the resource... |

| This paper analyses the impact of the 2003 CAP reform on Spanish agricultural sector in the context of the recent CAP Health Check and high food prices, using PROMAPA, a positive mathematical programming model for representative farms. The analysis compares the model results for base year 2002 to the findings for a scenario with the CAP reform measures in place, taking into account recent modifications. The effect of adopting a full decoupling scheme instead of the present partial decoupling is also studied. Brief descriptions are given of the PROMAPA model, the representative farm considered and the assumptions about both price variations and the policy measures simulated. The findings showed that the farming area for cereals grew substantially after... |

| Beef and pig production are important sectors affected by the cross-compliance policy. Full compliance with SMRs and GAECs generates costs and benefits which may have an impact on the competitiveness of these sectors on the world market. Compliance with the Nitrate Directive, animal identification and registration requirements and animal welfare standards can give rise to non-negligible cost of production increases at individual farm level and at sector level. Additional costs can be relevant either due to a low degree of compliance or by significant adjustments costs at farm level. Full compliance generates a level playing field between Member States of the EU, as some countries have to face higher additional costs than others, which are be attributed to... |

| The turnover of the EU agri-food sector overtops 2,000 billion Euros a year and employs roughly 22 millions workers. The focus of this paper is on the sectors directly linked to agricultural production and the food industry. Having a comprehensive understanding of extended agri-food economic linkages is critical when designing pertinent policies to deliver the full potential of strong EU agri-food and other bio-based sectors. A more disaggregated view is required. This study stars from a Social Accounting Matrices (SAM) for Spain with a highly disaggregated agricultural sector (AgroSAMs) for the year 2000. This study uses the AgroSAMs in its entire disaggregation, in order to provide a descriptive analysis of the agri-food and bio-based sectors. The limits... |
