Managing Rangeland as a Complex System: How Government Interventions Decouple Social Systems from Ecological Systems Ecology and Society
Li, Wenjun; Peking University; wjlee@pku.edu.cn; Li, Yanbo; Peking University; leeyu@pku.edu.cn.
The complexity of natural resource management is increasingly recognized and requires adaptive governance at multiple levels. It is particularly significant to explore the impacts of government interventions on the management practices of local communities and on target social-ecological systems. The Inner Mongolian rangeland was traditionally managed by indigenous people using their own institutions that were adapted to the highly variable local climate and were able to maintain the resilience of the social-ecological system for more than 1000 years. However, external interventions have significantly affected the rangeland social-ecological system in recent decades. In this paper, using livestock breed improvement as an example, we track government...

Greek cotton farmers' supply response to partial decoupling of subsidies AgEcon
Rozakis, Stelios; Tsiboukas, Kostas; Petsakos, Athanasios.
A mathematical programming model based on a countrywide sample of farms is used to assess the impacts of the new C.A.P on the supply of the cotton sector in Greece. Results show a decrease in cotton cultivated area along with the introduction of a new production system called "semi-abandonment cotton". Farm income is practically unchanged, largely due to the decoupled payments. When these payments are not considered, farm income turns negative in some cases, thus leading towards abandonment of activities.

CAP reform and its impact on structural change and productivity growth: A cross country analysis AgEcon
Kazukauskas, Andrius; Newman, Carol F..
The recent reforms of the Common Agricultural Policy (CAP) have exposed the European agricultural sector to a new set of constraints and challenges. The decoupling of direct payments from production is expected to make production decisions more market-oriented as farmers move from mainly subsidy revenue maximization objectives toward profit maximizing behaviour. However, ex-post analyses of the productivity of farms have yet to uncover any evidence of a positive effect of the decoupling policy on farm productivity. Using the Irish, Danish and Dutch farm level data, we identify the extent to which both system and product switching after the introduction of decoupling has occurred and to what extent these changes have contributed to productivity growth in...

Effects of policy instruments on farm investments and production decisions in the Spanish cop sector AgEcon
Kallas, Zein; Gil, Jose Maria; Serra, Teresa.
Our paper asses the impacts of the partially decoupled (PD) scheme, implemented during the 1990s and first half of the 2000s in the framework of the Common Agricultural Policy (CAP), on on-farm investment as well as on other production decisions. The Spanish COP sector was taken as a case study due to its economic and political relevance. The empirical analysis is applied on farm-level data from the Farm Accountancy Data Network (FADN), observed from 2000 to 2004, based on. We use a reduced-form application of the dual model of investment under uncertainty and a system of censored and non censored equations is estimated. PD payments are found to increase short-run production and to generate a statically significant increase in the investment in farm...

The effects of decoupling on Italian COP sector: an ex-post evaluation AgEcon
De Vivo, Carmela; Henke, Roberto; Pupo D'Andrea, Maria Rosaria; Vanni, Francesco.
One of the main objectives of the 2003 CAP reform was that to enhance farm competitiveness and make farmers able to catch market signals and adjust their production level and specialization accordingly. The aim of the paper is to evaluate the effects of decoupling in Italy COP sector comparing the estimated results of some structural and economic indicators of a sample of farms before and after the 2003 reform using data from the Italian Institute of Statistics and of the Italian Farm Accountancy Data Network (FADN). The analysis shows an improvement of income in farms that kept COP production specialization through the years under study. At the same time, farms that opted for a different specialisation in the post reform period improved their economic...

Facing decoupling: use of payments and investment reaction to decoupling in the EU AgEcon
Viaggi, Davide; Raggi, Meri; Gomez y Paloma, Sergio.
The main objective of this paper is to evaluate ex-post the effects of the 2003 reform, in particular decoupling, of the Common Agricultural Policy (CAP) in the European Union (EU), with a specific focus on farm investment behaviour. In the past years a number of studies have addressed the issue of the impact of EU policy reforms. However, long-term effects of policy changes and related impacts on structural and investment behaviour received relatively little attention. This study is based on a survey of farm households in a number of EU Member States. In the majority of cases, farmers stated they were indifferent to decoupling. Where any change occurred, the impact of decoupling was highly differentiated. Numerous reactions are better explained by various...

Environmental and socioeconomic impact of the new cotton reform AgEcon
Arriaza Balmón, Manuel.
Following the decoupling of the cotton subsidies in 2006 the production system has become less intensive in input usage with an average yield reduction of 40 per cent. Albeit the farm income has not been reduced, the reform has had a negative effect on the economy of some rural areas of Southern Spain, where there are few productive alternatives to cotton, with a 39% reduction of direct farm labour. Besides, the reform has been borne by the ginning industry (60% reduction), the agrochemical suppliers and the auxiliary sector. On the other hand, the environment has benefits from the extensification of the cotton production since three quarter of the production is now carried out under integrated production that implies a reduction in the amount of...

The Market for Payment Entitlements in Germany AgEcon
Roeder, Norbert; Kilian, Stefan.
In 2005, Germany implemented CAP decoupled payments. Direct payments were converted into tradable, production decoupled, single farm payments (SFP) by a hybrid model. From 2010 - 2013, there will be a gradual transition to a regional model. The following paper shows the results of an analysis of the market for payment entitlements in Germany between 2005 and June 2007. Data are derived from the German Central IACS database (ZID). In this period 1.2 of the 17 million payment entitlements changed their owner. A closer look at the figures reveals that despite a large difference in the face value of the entitlements, the entitlements are rarely traded in order to optimize farm budget. In most cases, trade of entitlements is directly linked to farm or land...

Do decoupled payments really encourage farmers to work more off farm? A micro-level analysis of incentives and preferences AgEcon
Douarin, Elodie.
According to neo-classical theory, farm operators’ labour allocation is determined by the relative wage they can earn from their labour on and off the farm. At the equilibrium, time should be allocated so that the marginal returns from on- and off-farm work are equal. Thus, a move from coupled to decoupled payments should have important impacts on labour allocation, as it reduces the return to farm labour and increases the unearned income of operators. However, empirical studies on decoupling have shown so far only limited impact from decoupling and sometimes contradictory findings. In this paper, individual preferences and constraints are taken into account to try and identify potential barriers to labour allocation adjustment. Empirical analysis based on...

Short- and mid-term prospects of the main agricultural sectors in Hungary: a model based analysis with a methodological overview AgEcon
Himics, Mihaly; Potori, Norbert.
In our paper, we briefly discuss the outlook for the main agricultural sectors in Hungary until 2013, and present some of the latest results of our modelling work at the Research Institute for Agricultural Economics (AKI). In addition, we provide a short methodological overview of the applied modelling tools. To strengthen the quantitative analysis capacity during the pre-accession period, AKI developed a partial equilibrium model (Hungarian Simulation Model or HUSIM) by the end of the 1990's. Since then, AKI has been regularly carrying out agricultural policy analyses by applying this economic model. After gathering experiences with HUSIM, strong demand was raised on a modelling tool that enables us to investigate the structural changes in agriculture in...

THE EFFECTS OF SINGLE FARM PAYMENTS ON SCOTTISH AGRICULTURE: A CGE MODELING APPROACH AgEcon
Gelan, Ayele; Schwarz, Gerald.
Using a CGE model calibrated on Scottish data, this paper examines two important issues related to evaluating impacts of the Single Farm Payment. These are specification of product transformation functions and investigation into supply elasticity parameter. Simulation results from a standard CGE were compared with those from an alternative optimisation framework proposed in this study. The latter yielded a policy effect that is likely to represent behaviour of a profit maximising farmer. The parameter sensitivity analysis showed the important role differences in supply conditions can play; which implied a need for further econometric studies to estimate supply parameters.

Production Effects of Agri-environmental "Green Box" Payments: Empirical Results from the EU AgEcon
Salhofer, Klaus; Streicher, Gerhard.
Agri-environmental programs are part of the green box of the GATT Uruguay Round and are supposed to "have no, or at most minimal trade distorting effects or effects on production." In addition, "the amount of payment shall be limited to the extra costs or loss of income involved in complying with the government programme." Utilizing farm accounting data we estimate the effects on yields for ten agri-environmental programs in Austria, which account for 12% of EU's budget expenditures for agri-environmental programs. Only three out of these ten programs have significant negative effects on yields, while one program has a significant positive impact and the rest has no significant impact. These results suggest that there are serious windfall profits...

Evaluating the Effects of Decoupled Payments under Output and Price Uncertainty AgEcon
Kotakou, Christina A.; Katranidis, Stelios D..
This paper examines the effects of decoupling policies on Greek cotton production under the hypothesis that producers face uncertainty about output price and quantity. Using our estimation results we simulate the effects on cotton production under four alternative policy scenarios: the ‘Old’ CAP regime (i.e. the policy practiced until 2005), the Mid-Term Review regime, a fully decoupled policy regime and a free trade-no policy scenario. Our results indicate the decoupled payment will have two contradictious effects on risk aversion. Producers become less risk averse through the wealth effect but more risk averse because of the increased output variance. The overall result of these two effects depends on the degree of risk aversion by farmers. We found that...

The Role of Risk in the Decision to Produce Post-Decoupling - A Stochastic Budgeting Example AgEcon
Thorne, Fiona S.; Hennessy, Thia C..
Under the Mac Sharry and Agenda 2000 reforms, direct payments comprised a significant portion of farmers' income in the EU. Farmers had to engage in production to receive these payments but the payments were relatively risk-free and therefore risk may not have played an important role in the production decision. This paper considers the effect of the decoupling of direct payments from production in the EU and in particular, on the role of production risk in the decision making process. In an environment where direct payments are completely decoupled from production, farmers may engage in an 'entitlement farming' system, that is retain their land only to activate the decoupled payment and not actually produce any tangible goods. This paper examines the...

How Decoupled Is the European Union's Single Farm Payment? AgEcon
Halmai, Peter; Elekes, Andrea; Velikovszky, Laszlo.
Our paper focuses on the key element of the 2003 CAP reform: on the single farm payment (SFP). The basic aim was to decouple direct payment from production decisions. Because of the widespread agricultural policy reforms (support producers with the least possible distortions) and of the on-going WTO negotiations, this is an issue attracting significant attention on behalf of agricultural economists. Different tools and different methodologies have been employed in the effort to better understand and rank policy measures in terms of their production and trade effects. Most of the literature classifies measures based on implementation criteria. Our paper assesses the decoupled nature of the single farm payment (SFP) based on WTO and OECD criteria. The EU...

WINNERS AND LOSERS OF POLICY CHANGES – WHAT IS THE ROLE OF STRUCTURAL CHANGE? AgEcon
Sahrbacher, Christoph; Kellermann, Konrad; Balmann, Alfons.
In this paper several decoupling options are evaluated concerning their impact on structural change especially on farm incomes and their surviving. Therefore, the agent-based model AgriPoliS was used and extended to account the income of leaving farms. This enables the comparison of future incomes of leaving and surviving farms to find out whether leaving farms are losers or not. The disaggregated analysis of farms’ household incomes showed that leaving farmers even benefit from their decision in case that enough off-farm jobs are available. Losers are farms that would have left agriculture under conditions of the Agenda 2000. After decoupling they stay in the sector and cannot increase their income as much as under Agenda conditions. Furthermore, the...

Modellierung der Auswirkungen einer Entkopplung der Direktzahlungen in der EU auf die Flächenallokation und Wiederkäuerproduktion: Eine Analyse unterschiedlicher Modellergebnisse AgEcon
Balkhausen, Oliver; Banse, Martin; Grethe, Harald; Nolte, Stephan.
Decoupling of direct payments can be expected to have complex effects and the net effect on crop and fodder acreage is unclear. A literature review reveals that various simulation models uniformly project a decline of the cereal and silage maize acreage as well as ruminant production in the EU-15 in the course of decoupling of direct payments. In contrast, model results are mixed with respect to the direction of the decoupling effect on oilseed and pasture as well as voluntary set aside area. The model type is not found to have a systematic effect on model results. It is rather the assumptions about the effects of direct payments on production which differ widely and drive model results to a large extent. A model analysis which is based on the partial...

Effect of decoupling and agri-environmental policy on biodiversity in the uplands in UK AgEcon
Acs, Szvetlana; Dallimer, Martin; Hanley, Nick; Gaston, Kevin J.; Armsworth, Paul R..
Recent decades have witnessed substantial losses in biodiversity in Europe, principally driven by the ecological changes associated with intensification of agricultural production. These changes especially affected the biodiversity in the marginal areas, such as the uplands in UK, since the habitat change was greater than in lowland zones. Livestock farming is the main land use in these areas, and economic viability of these farmers substantially relies on income coming from agricultural subsidies and different agri-environmental payments. The production decisions are influenced by these incentives and those have a subsequent effect on biodiversity. In order to address the problem of economic viability of farmers together with its impact on biodiversity...

Analysing the Impact of Decoupling at a Regional Level in Ireland: A Farm Level Dynamic Linear Programming Approach AgEcon
Shrestha, Shailesh; Hennessy, Thia C..
This paper describes a methodology to assess the impact of the decoupling of payments on Irish farms at a regional level. The methodology is based on a farm level dynamic linear programming model which optimises regional gross margin under a set of constraints. Regionally representative farms are selected using cluster analysis. The model maximises aggregate gross margins from all the farm types in a region allowing land and milk quota to transfer between farms within the region. The model is estimated for a baseline scenario, assuming no policy change, and under a decoupled scenario where farm payments are fully decoupled from production. An example of an impact study at the Border region in Ireland is presented in this paper to demonstrate the methodology.

Impacts of the flat rates and digressive schemes on the distribution of Direct Payments in the EU AgEcon
Kleinhanss, Werner.
The Mid-Term Review and the Health Check reforms of the EU’s Common Agricultural Policy (CAP) include numerous options for national implementation of the Single Payment Scheme. After the far-reaching decoupling of Direct Payments, a further reform of the Common Agricultural Policy is necessary with respect to the financial guidelines to be established for the period after 2013. Referring to Germany, the principles of the hybrid and regional models and their effects on the distribution of Direct Payments are shown. With regard to future CAP, the impacts of alternative payment options are analysed based on farm individual FADN data of EU-27. Options of digressive premium schemes, including capping with regard to labour input and regionalised or EU-wide flat...
