+ | |||
+ | ===CAP 2014-2020=== | ||
+ | |||
+ | From 2014 onwards, a new agricultural policy entered into force. The key elements of the policy were (i) convergence of payment rates between member states and farmers within member states, (ii) the expansion of the option to use coupled support beyond the previous articles 68/69, and (iii) the introduction of three “greening requirements”. These elements were introduced into CAPRI, and their use can be inspected in the commonly used baseline policy file “gams\pol_input\cap_after_2014\ref.gms”, | ||
+ | |||
+ | {{: | ||
+ | |||
+ | Since the mechanisms behind each of the three elements is somewhat complex, the file relies on include files to define each of the three components. The include files are stored in the scenario directory (gams\scen) of the CAPRI system, and which particular include files to use is indicated by the string variables ($setGlobal) in the first three code lines. The actual logic of the policy file, also the inclusion of the indicated three files, takes place in the file included in the final line, referred to as the base scenario file. | ||
+ | |||
+ | // | ||
+ | |||
+ | {{: | ||
+ | |||
+ | Two different uses of the convergence mechanism are illustrated by Austria and Greece, which apply very different models. Austria applies the full convergence using a linear model over time, with the same target payment rate in all of Austria. The convergence should be complete in 2019. This is obtained by assigning all Austrian regions to one generic “BPS-region”, | ||
+ | |||
+ | {{: | ||
+ | |||
+ | Greece applies different models for different types of regions, depending on the character of agriculture in the region. We approximate this in CAPRI by classifying the NUTS2-regions according to the shares of arable land, grass land and permanent crops in a historical year (2008). Based on those shares, three BPS-regions are created, within each of which the same convergence model is applied. The convergence is linear, but with the additional 30-percent-rule applied, defining that no farm (supply model region) should get more than 30 percent higher payments per hectare than the average of the BPS-region. Convergence proceeds up to the year 2019, and in each year, the lower limit for convergence, | ||
+ | |||
+ | {{: | ||
+ | |||
+ | The code implementing the logic behind these various settings is generic and found in the file “gams\policy\implement_bps.gms”. The result is a payment per region, defined using the general premium mechanism of CAPRI, that is called “dp_bps” and with the eligible activity list “pgsaps”. The application type is “perLevl” and the budget is set on national level in the base scenario file “gams\scen\base_scenarios\cap_2014_2020.gms”. | ||
+ | |||
+ | //Voluntary Coupled Support// is defined using the standard premium mechanisms of CAPRI, based on notifications received from the European Commission. We have interpreted the notified target activities in terms of CAPRI activities, and set budget ceilings and nominal amounts in the file “gams\scen\premiums\coupling\cap_2013_2020_vcs.gms”. | ||
+ | |||
+ | The //Greening Measures// can be steered by the modeller. Even though the greening in itself is complex in implementation, | ||
+ | |||
+ | {{: | ||
+ | |||
+ | The first statement defines the share of the national pillar 1 envelope that is dedicated to the “greening top-up”. By default, this is 30%. Then, a set of active greening measures is populated. There are three options available, and by default, they are all active: | ||
+ | |||
+ | * The share of permanent grass land to arable land cannot decline relative to the base year. | ||
+ | * A minimum measure of crop-diversity must be maintained. | ||
+ | * A share of land must be allocated to certain activities counting as “ecological set-aside”. | ||
+ | |||
+ | The shares of activities eligible as ecological set-aside is then defined in the concluding parameter definition in the file. The set-aside rate itself is defined as a string variable “$setglobal greening_setasiderate 5”, defining it to be 5% by default. The three greening restrictions are implemented as constraints in the supply models. The greening top-up is implemented as a standard CAPRI premium called DPGREEN. The logic behind the greening restrictions is activated in the include file “// | ||
+ | |||
+ | The CAP 2014-2020 also contains three more payment schemes: Support to young farmers, support to smaller farms (first hectares) and support to areas with natural constraints (ANC). These payment schemes, with their associated budgets, are defined in the base scenario file. | ||

+ | ===Tradable Single Premium Scheme entitlements=== | ||
+ | |||
+ | With the so-called Mid Term Review of the Common Agricultural Policy, the so-called Single Farm Premium (SFP) as a decoupled payment was introduced which is implemented as a subsidy which does not require production, is subject to cross-compliance and paid per ha up to a number of entitlements. The original entitlements, | ||
+ | |||
+ | In CAPRI, the assumption in the baseline is that all hectares used by agriculture are able to claim the SFP and that any unused entitlements had been removed so that the SFP becomes fully capitalized into land. Subsequent changes in the premiums including the SFP, prices or other policy instruments in a counterfactual run could decrease the marginal returns to agricultural land. Based on the land supply curve implemented in CAPRI, agricultural land use would shrink and some entitlements become unused. Vice versa, if changes let the marginal return to land increase, the entitlements become the limiting factor to claim the subsidy. The increase is thus mapped into an economic rent to the entitlement. If changes generate rents on entitlements in some farm types and not in others, one would assume that trade in entitlements will occur. A simple algorithm to trade the entitlement is now included in CAPRI and described below. | ||
+ | |||
+ | //Switching on the entitlement trade// | ||
+ | |||
+ | The trade module is implemented in the file ‘// | ||
+ | |||
+ | {{:: | ||
+ | |||
+ | By default, the entitlement trade is switched OFF in the general settings file of CAPMOD, called gams\capmod\set_global_variables.gms | ||
+ | |||
+ | {{: | ||
+ | |||
+ | The basic idea of the module is very simple: shift entitlements from farm type or regions which unused entitlements to other farm types or regions which have an economic rent on their entitlements. The trading entities should receive the very same premium on the entitlement for the current implementation in the code. One should hence set the trade level according to the regional level for which flat rate premiums are implemented as shown below in an example: | ||
+ | |||
+ | {{: | ||
+ | |||
+ | //How the entitlement trade works// | ||
+ | |||
+ | The following code pieces are taken from ‘// | ||
+ | |||
+ | {{: | ||
+ | |||
+ | From these a maximum of 10% is defined as the demand in each iteration: | ||
+ | |||
+ | {{: | ||
+ | |||
+ | In order to take differences in the marginal returns into account, an indicator based on the squared value is used: | ||
+ | |||
+ | {{: | ||
+ | |||
+ | It serves as the distribution key of unused entitlements, | ||
+ | |||
+ | {{: | ||
+ | |||
+ | Next, the number of unused entitlements is stored: | ||
+ | |||
+ | {{: | ||
+ | |||
+ | As seen, only 50% of the unused entitlements are released in any iteration. We next determine the size of the markets, i.e. total demand and supply: | ||
+ | |||
+ | {{: | ||
+ | |||
+ | The supply is then distributed according to the squared value of the individual demanders | ||
+ | |||
+ | {{: | ||
+ | |||
+ | //An example printout// | ||
+ | |||
+ | The following code snippet shows an example for a NUTS2 regions and the related farm types for a test run for Greece without the market module: | ||
+ | |||
+ | {{: | ||
+ | |||
+ | As seen from above, we have two farm types in the starting situation which acts as demanders, i.e. have a marginal value on their entitlements (016 and 999). Their marginal value on the entitlement is quite high in the starting situation with > 125 € / entitlement. We have also a total of 3639 ha after the first round of unused entitlements which can be sold to the demanders. Distributing half of them (ca. 1800 ha) to the two demanders reduces the marginal value of the entitlements already below 95€, the next round distributed ca. 900 ha and brings the price down to 50€ until in the last round almost nothing is left for distribution and the value of the entitlements has dropped below 10€. The reader should note the trade is not yet taking into account in the income calculation of the farm types. | ||
+ | |||
+ | Finally, we come to the main point which motivated the introduction of that module. As indicated above, we interpret the SFP as a subsidy to agricultural land use which at the margin is capitalized in the land rent. It thus increases the marginal returns to land use in agriculture. In our baseline, we start with a situation with an assumed equilibrium in land markets, i.e. marginal returns in agriculture including any subsidies are equal to marginal returns of alternative uses. | ||
+ | |||
+ | Reducing the SFP will render agricultural land use less competitive so that land owner will rent out less to agriculture and put the land into other uses. That effect can be clearly seen below in the first iteration: in the farm types where the SFP drops due to uniform SFP at NUTS2 in Greece, land use is reduced. Total land use in Greece drops by 1.2%. But if we re-distribute the subsidy between farm types, farms which were competing before with below average subsidies against alternative land use possibilities now would like to expand land use. Without additional entitlements, | ||

+ | ====Pillar II==== | ||
+ | |||
+ | ===Overview=== | ||
+ | |||
+ | Modelling of Pillar II for an EU-wide assessment provides a specific challenge given data availability regarding measures which are programmed and implemented at Member State or even regional level. Official reporting of measures under Pillar II in standardized data bases uses a rather rough categorisation, | ||
+ | |||
+ | The most important measures from a budgetary view point are the Agri-Environmental Schemes and the Less Favourite Area Payments. Therefore some care must be taken to model these measures accurately. The project draws here on the work of a study by LEI and IEEP (LEI and IEEP 2009) for DG-AGRI, which use in the case of the agri-environmental payments analysis based on FADN and for LFA based on FADN and CLUE (Verburg et.al. 2010) results. | ||

+ | |||
+ | ===Modelling of LFA=== | ||
+ | |||
+ | The LFA measure was implemented as a direct payment to cropping and grassland, with the same amount for all cropping activities except for fallow land. The first challenge encountered when implementing the LFA premiums is that the regions do not coincide with the administrative regions used in CAPRI. – Recall that CAPRI only has one single representative firm in each nuts 2 region (or up to nine farm types). In reality, thus, only a share, generally much less than 100%, of the land in a nuts region is eligible for LFA payments, and it may very well be the case that the agricultural production on that land is different from the regional average. For example, one may expect that a mountainous LFA area contains more grass land than the surrounding flat land agricultural areas in the same nuts 2 region. In order to capture a possible bias of this nature, a GIS tool (CLUE-model) was used to compute the shares \(S_{ij}\) of LFA in different broad land use classes //j// \(\in\) {non-irrigated arable land, irrigated arable land, pasture, permanent crops} in each region //i//. Those shares were used to compute a (potentially) different nominal premium amount for crops belonging to each class //j//. The so computed different amounts were taken to reflect the biased distribution of crops inside and outside of LFA regions. Since CLUE does not distinguish “Mountainous” and “Other” LFA, the nominal amount //A// to which the shares //S// were applied was assumed the same everywhere: 250 euro, the maximum amount in mountainous LFA regions. | ||
+ | |||
+ | \begin{equation} | ||
+ | P_{ij} =AS_{ij} | ||
+ | \end{equation} | ||
+ | |||
+ | where \\ | ||
+ | //P// = Premium per hectare \\ | ||
+ | //i// = Region \\ | ||
+ | //j// = Group of crops \\ | ||
+ | //A// = Maximum amount per hectare, 250 euro \\ | ||
+ | //S// = Share of LFA in all land of class //j// \\ | ||
+ | |||
+ | A value ceiling for the premium was computed by adding the budgets for the component measures. Recall that the premium module of CAPRI will apply a cut factor to the amount P such that the ceiling is not overshot. | ||
+ | |||
+ | In economic terms, the potentially different premium rates for different groups of crops has a production effect, so that the type of production in CAPRI that receives the higher rates may expand on the expense of other activities. The interpretation would be that more farmers in the LFA areas comply with the LFA eligibility rules and modify their production plans to comply with the criteria there. Nevertheless, | ||
+ | |||
+ | === Modelling of N2k === | ||
+ | |||
+ | Each production activity in CAPRI is split into a low and high yield variant with adjusted input coefficients, | ||
+ | |||
+ | The interpretation is the following: If more money is spent on the measure, more farmers within the designated areas may switch to extensive agriculture. Then the average payment per hectare of the nuts 2 region would increase, reflecting that a larger share of the farmers now participate in the measure. It is today indeed the case that not all farms within an N2k area receive support. | ||
+ | |||
+ | ===Modelling agri-environmental payments=== | ||
+ | |||
+ | The agri-environmental payments is a very diverse set of measures, which accounts for the largest share of the second pillar. In the modelling approach opted for here, with one aggregated measure “05 agri-environment”, | ||
+ | |||
+ | The method for “nationalization” of the AE scheme employed here is to use the distribution of the sum of the AE measures, i.e. the measure allocated to class 05, to agricultural sectors using the receipts by farm types according to FADN in 2005 as key. This implies linking the support to production. Whether this corresponds to reality is an empirical question. It is doubtless the case for some measures in some regions, but certainly not so for all AE measures in all regions. Refining the implementation would thus involve conditioning the support on technical constraints. Nevertheless, | ||
+ | |||
+ | **Table 27: Mapping from aggregated farm types in FADN (TF8) to activity groups in CAPRI** | ||

+ | |||
+ | The agri-environmental (AE) payments are implemented as extensification subsidies, and they are distributed to regions based on the distribution of less-favoured areas across regions. However, the distribution is modulated by the national level shares of farms in or out of LFA receiving AE support. We needed the following two probabilities: | ||
+ | |||
+ | p_landPartition(ru, | ||
+ | |||
+ | p_aeLfa(ms, | ||
+ | |||
+ | Then, the payment rate for each region is set in proportion to the weighted share of farms likely to have some AE support, predicted by the regional share of each land class (grass, arable) being classified as LFA in each region times the share of farms in/out of LFA having AE-support in the national FADN sample. The computation takes place in policy\rd_logic.gms: | ||
+ | |||
+ | {{:: | ||
+ | |||
+ | Note that the code does not know how high the absolute level of payments shall be for each region, but allocates the relative levels. Then, the national ceiling for AE payments are applied to adjust all regional payments until the ceiling is respected. | ||
+ | |||
+ | Finally, an extensification effect to the AE payments is introduced using the possibility to make technological variants differently eligible. | ||

+ | |||
+ | **EU and national budget contribution** | ||
+ | |||
+ | The reporting part of the system was expanded to account for (co-)financing rates of the different schemes, so that contributions from EU and national budgets can be differentiated. The underlying factors are currently defined in // | ||
