Commissioner Hogan believes that this enhanced subsidiarity will make it possible to better take into account local conditions and needs.
In future, it will be the Member States that will define eligibility conditions that are most suited to their particular circumstances.
This is expected to produce a substantial simplification of the requirements that farmers must fulfil to receive payments.
Giving even more responsibility to Member States to design and implement agricultural policy, albeit within a framework defined at EU level, means that agricultural policy will increasingly be a national matter. This will lead to a more lively and animated debate about Ireland's national agricultural priorities than we have experienced heretofore.
Ireland will have options on how to use the money allocated under the CAP budget. The two Pillar CAP structure is maintained.
There is a small cut in Ireland's direct payments allocation under Pillar 1 in nominal terms of 4pc which will affect farmers' payments from 2020 onwards. There is a bigger cut of 15pc in the Pillar 2 rural development allocation, although Ireland will be expected to contribute more national resources through a higher co-financing rate which will help to offset this reduction.
As under the current CAP, Ireland will have the option to shift up to 15pc of its Pillar 1 ceiling to rural development, or vice versa. It could in addition transfer up to a further 15pc of its Pillar 1 allocation to Pillar 2 interventions designed to benefit the environment and climate.
There is also a requirement to introduce an eco-scheme funded by the Pillar 1 direct payments allocation which could be used to pay for some agri-environment-climate measures.
How large a share of the direct payments allocation should be used for this scheme will be for Ireland to decide, but the overall resources committed to environmental and climate action compared to the current CAP cannot be reduced.
For the first time, the option is given to move away from the entitlements basis for direct payments and to make payments per eligible hectare that can be differentiated by socio-economic or agronomic conditions.
If Ireland stays with the entitlement system, there will be an obligation to pursue further 'internal convergence' to ensure that no payment entitlement has a value less than 75pc of the national average value by 2026.
At least 2pc of its Pillar 1 allocation must be used to support young farmers, but this could be done either by means of a top-up in direct payments or through installation aid.
There is a requirement to cap direct payments after deducting labour costs at €100,00, but an option to reduce this cap to €60,000. However, the ability to deduct labour costs including the value of family labour before the cap is applied will make this provision rather meaningless in practice.
Ireland will also have to introduce a redistributive payment for smaller and medium-sized farms.
The additional amount per hectare and the maximum number of hectares that will qualify are national decisions. Given the likely very limited proceeds from capping which is intended to finance this payment, it is hard to see it amounting to much.
Ireland will again have the opportunity to use coupled support up to 10pc of the value of its direct payments allocation (12pc if the additional amount is used for protein crops).
For the first time, energy crops are included in the list of commodities eligible for coupled support.
The legislative proposals envisage that the CAP Strategic Plan should be ready by January 1, 2020. This would mean setting preparations in train by the end of this year.
This assumes that the legislation is approved by the Council and Parliament before the Parliamentary elections in May next year. If this does not happen, all bets for the CAP post 2020 are off.
