2.1. Data description

The vineyard data set includes data on the structure of vineyards in the European Union. It covers the holdings growing vines intended to produce grapes for other purposes than table grapes or growing plants for vegetative propagation of before mentioned vines and the area covered by these vines.  The data concerns the vine types, degree of specialisation of vine-grower holdings, main varieties of grapes and age of plants. Some indicators are collected at national level, others a NUTS2 level.  The data are extracted from the vineyard register. The Member States, which have more than 500 ha of vines for other purpose than table grape production need to collect the data.

2.2. Classification system

The classification system used in the vineyard data has several dimensions:  type of vineyards, degree of specialisation of the holding, main varieties (> 500 ha t national level), age of plants and size classes of holdings. More information can be found in the Handbook.

2.3. Coverage - sector

Growing of grapes for other purposes than table grapes (mainly for wine, juice, raisins) (part of NACE rev.  2 classification of A01.21: growing of grapes) and plant propagation for vines (part of NACE rev.  2 classification of A01.30: plant propagation).

2.4. Statistical concepts and definitions

Statistical characteristics of observations

Data refer to vineyard parcels.

Is there a national legislation covering structural vineyrd statistics? NO
Name of the legislation
If yes, provide a link
Scope and coverage of the legislation
Responsable organisation for the legislation
Precision requirements 
Does the national legal frame foresee the use of the vineyard register?  YES
2.5. Statistical unit

Number of holdings growing vines intended to produce grapes for other purposes than table grapes or growing plants for vegetative propagation of before mentioned vines and the area covered by these vines in hectares.

2.6. Statistical population

All holdings growing vines intended to produce grapes for other purposes than table grapes or growing plants for vegetative propagation of before mentioned vines, having an area bigger than 0.1 hectares registered in the vineyard register. The data collection is limited to the countries having a bigger than 500 ha area of vines grown for other purposes than table grapes.

2.7. Reference area

Greece

2.8. Coverage - Time

When was the first (regular) structural vineyard survey / data collection organised?

Year 1982, based on (EEC) 357/79.

 

Frequency of the data collection (if there was one) before 1979 or before EU membership?

Data on the area and production of vineyards are collected every year, since reference year 1961, through the Annual Statistical Agricultural Survey. The survey is conducted for national reasons in order to collect statistical data on the cultivated areas under several crops and on the production of agricultural and livestock products, as well as the agricultural machinery used. The legal frame for the survey is the Royal Decree No 111/15-2-1962. The statistical unit of the annual agricultural survey is the land area (not the holding), which is included within the administrative boundaries of every Municipal/Local Community of Greece and it is a census survey. The survey covers all the Departments (NUTS 3) and the Municipal / Local Communities (LAU 2) of Greece.

 

If not regularly, in which years the vineyards have been surveyed ?
2.9. Base period

 The data extraction date for the Vineyard survey was the 31 July 2015.

Additional comments

Data on PDO and PGI were not of sufficient quality according to the responsible authority and were not transmitted to ELSTAT. The identification of PDO and PGI was a task undertaken by ELSTAT (see 6.3.3). 

Data on the propagation material of vines from an ancillary source were used for crosschecking.

 

3.2. Frequency of data collection

The EU-level vineyard data collection is done every 5 years under Regulation (EU) 1337/2011. The first data collection takes place 2015. From 1979 until 2009 there was a data collection done every 10 years (basic data) and a smaller annual survey yearly (Council Regulation (EEC) No 357/79 on statistical surveys under vines).

Have you done any national data collections on the structure of vineyards since the 2009 EU-level data collection and before the 2015 EU-level collections? YES
If yes, in which years were they implemented?

2012 and 2013


Additional comments

Although the new Regulation (1337/2011) was in force, a vineyard survey based on the pervious regulation (357/79) was conducted for the years 2012 and 2013.

 

3.3. Data collection

How easy was it  to get access to the vineyard register data (administrative access)?  
The data provider has direct constant access to the vineyard register
Access was granted upon a simple request
Access was granted after some negotiations
Access was granted after lenthy negotiations 
Access was not granted
Were the data from the vineyard register integrated into a statistical holding register? NO
If not, what were the reasons for not doing that?  
There was no need for such an operation
It was not technically possible because of lack of common identifier
It was not feasible due to data protection issues
It was considered too expensive
Other reasons


Additional comments

Vineyard register data were used for comparison and updating of ELSTAT statistical farm register.

ELSTAT keeps a statistical farm register which is the frame for all agricultural surveys. This register has resulted from the agricultural census (2010) and is updated on the basis of the annual agricultural surveys and the FSS.

This register is also updated using information from administrative sources such as: the organic farming register, the new farmers register, olive cultivation register and vineyard register kept by the Ministry of Rural Development and Food.

There is also an ongoing process of updating ELSTATs register using OPEKEPEs (Payment and Control Agency for Guidance and Guarantee Community Aid) files (IACS).

 

3.4. Data validation

Which kind of data validation measures are in place? Automatic and Manual
What do they target?  
Unit completeness
Item completeness
Valid value
Time series ranges (outlier detection)
Relational checks between characteristics
Arithmetic calculations (e.g. correctness of aggregates)
Others
Is the data cross-validated against another dataset? YES
If yes, which dataset?  
Previous results of vineyard statistics
Annual crop statistics area data
FSS data 
Other dataset

Annual Statistical Agricultural Survey (National survey).

Additional comments

The answer "NO" to the question about the availability of a Quality Report, concerns the Vineyard Register. Quality reports for vineyard statistics (previous surveys) are available on ELSTAT’s website (see 9.7). The press release for the vineyard statistics 2015 and the relevant Quality Report are scheduled for 30 November 2016.

In November 2014 Eurostat has carried out a peer-review for ELSTAT. The peer-review was related to the compliance of the Authority with the European Statistics Code of Practice (CoP). No specific domain of statistics was covered.

 

4.2. Quality management - assessment

   Grading  Comments
How would you describe the overall quality of the structural vineyard statistics?  Satisfactory

The main factors affecting the overall quality are the accuracy and the comparability.

How would you describe the relevance of the structural vineyard statistics?  Very good
How would you describe the accuracy of the structural vineyard statistics?  Satisfactory

Coverage errors and incorrect data entry of some characteristics have an impact on the accuracy of the results.

 

How would you describe the comparability of the structural vineyard statistics with other agricultural statistics, e.g. FSS and Annual Crop Statistics?  Satisfactory

Due to the different methodology applied from the various sources, data are not fully comparable (see 8.3).

 

How would you describe the coherence (over time) of the structural vineyard statistics?  Satisfactory

Due to the different data collection methods between the previous years and 2015 (surveys versus administrative data) data are not fully coherent over time.

 

How would you describe the coherence (across regions in your country) of the structural vineyard statistics?  Very good

 

 

How would you describe the accessibility of the structural vineyard statistics?  Very good

6.3. Non-sampling error

Over coverage and misclassification errors are observed in vineyard register data (see 6.3.1)

6.3.1. Coverage error

In the context of vineyard data collection the non-sampling errors are linked to the quality of the vineyard register

Under coverage

Does the vineyard register include all wine growers of the country? NO
If not, which kinds of wine growers are not included?

The register includes all growers who have submitted viticulture statement from 2004, when the register was established, and onwards. Growers who have not submitted viticulture statement are not included in the register.

How many percent of the total number of wine growers are not included?

Not estimated

How big part of the vineyard area is not included?

Low

Impact of under coverage on the data quality Low


Over coverage

Does the vineyard register include holdings which are not any more active wine growers? YES
If yes, how many years does an inactive holding stay in the register?

Register data are updated according to grower’s declaration. In order for a parcel to be removed, the grower has to declare it as abandoned or non productive vineyard.

 

Are former wine grower holdings, which haven't harvested the grapes for more than 7 years, part of the vineyard data collection? YES
Impact of over coverage on the data quality Moderate


Multiple listing errors

Number of farms listed in the register several times? None
Impact of multiple listings on the data quality None

If yes, to which extent? Some
Which characteristics are affected?  
Area
Number of holdings
Type of production
Size class
Degree of specialisation
Main varieties
Age class
   
Impact of misclassification on the data quality  Moderate
   
Degree of bias caused by coverage errors Moderate
What measures were taken to mitigate the impact of coverage errors?  
None
Ancillary data sources were used in parallel to the vineyard register
Statistical correction methods
Others

Checks were made by the responsible authority. When necessary, data are sent back to the Regional Directorates of Rural Economy and Veterinary (responsible at regional level for the maintenance of the register) for verifications.

 

   
In case coverage errors were detected, was the authority responsible for the vineyard register notified? YES
Have actions been taken to improve the register? YES


Additional comments

Under coverage: The percentage of growers not included in the register is considered insignificant, since the registration in Vineyard Register is compulsory for growers who take part in the wine sector programs and actions.

Misclassification: Possible incorrect data entry in the fields of the vineyard register forms concerning parcel characteristics may relate to all of cartographic and descriptive information of the parcel: errors in the geographical identification, the declared area, variety, vineyard designation etc.


6.3.2. Measurement error

Not available.

6.3.3. Non response error

In the context of vineyard data collection the non-response is understood as missing characteristics in the vineyard register

Were all characteristics mentioned in Regulation 1337/2011 Annex 2 present in the vineyard register? YES
If not, which were missing?
Were ancillary data sources used to fill in the gaps? NO
If yes, which one?


Additional comments

Data on PDO and PGI were not transmitted to ELSTAT because they were considered of low quality.

ELSTAT has proceeded to a number of actions in order to clarify register data and fill in the gaps.

The geographical identification of the location of the parcel in the register is based on previous administrative divisions of the country (Kapodistrias 2001 and 2009) instead of the current one (Kalikratis, latest version 2015). So firstly, the correspondence between the old and the new geographical codes was performed.  

At a second stage vines eligible for PDO and PGI wines were identified. This task was performed by ELSTAT, since the relevant information in the vineyard register is based on the producer’s declaration and is not crosschecked. According to the Ministerial Decisions of recognition of the PDO and PGI wines, ELSTAT has proceeded to the recording of all combinations of geographical codes and varieties that can produce PDO or PGI. Thus each parcel in the registry was characterized as potentially PDO/PGI or not.

How would you describe the impact of the differences in definitions for the data comparability at EU level? Very small


Additional comments

8.2. Comparability - over time

Was the national methodology used for compiling 2009 and 2015 structural vineyared data comparable?  Major differences
Were the definitions used for compiling 2009 and 2015 structural vineyared data comparable?  Minor differences
Was the regional breakdown used for compiling 2009 and 2015 structural vineyared data comparable?  Same NUTS2 regions


Additional comments

Concerning the methodology used, in 2009 a survey was conducted, while 2015 data are based on administrative source (vineyard register).
Concerning concepts and definitions, in ELSTAT’s register, which was the frame for the previous vineyard surveys, the basic unit is the agricultural holding, while in the Vineyard Register the basic unit is the holder/producer. However, more than one holder may participate in the same holding. For this reason the number of holdings is not fully comparable between the two surveys (previous vineyard surveys and vineyard register). Additionally, in the previous vineyard surveys: 1) there was no information collected about PGI and 2) varieties currently recorded as dual purpose, were included in table grapes varieties or raisins since this is their main orientation.

 

8.3. Coherence - cross domain

With which other data sources the vineyard data have  been compared?  Annual crop statistics (ACS) and FSS
Other statistics

Previous vineyard surveys, Annual Agricultural Survey (national survey)

 

Other registers

ELSTAT’s statistical farm register

 

   
If no comparisons have been made, why not?
Result of the comparison with ACS Small differences
If differences were detected, to which characteristics are they linked ? Area by grape type
Description of the differences

Area under wine grapes is 20% larger in vineyard statistics 2015 than in ACS 2015 (see also additional comments).

ACS data are estimates obtained primarily from the agencies located in the regional divisions of the country. They are based on the premise of the opinions of experts in the agricultural sectors (local agriculturists, cooperatives, local farmers, etc.)

 

Result of the comparison with FSS Small differences
If differences were detected, to which characteristics are they linked ? Area by grape type
Description of the differences

Area under wine grapes is 24% larger in vineyard statistics 2015 than in FSS 2013 (see also additional comments).

FSS (as well as previous vineyard surveys) is conducted by ELSTAT on the basis of ELSTAT’s statistical farm register (see 3.3). Comparing ELSTAT register with Vineyard register, the large difference is observed for holdings <30 ha, while the difference in the higher classes (>30ha) is insignificant. A part of the difference is due to the over coverage error in the vineyard register (see 8.3), while the rest part should be further examined whether it is created by holdings missing from ELSTAT’s register.

 

Other comparison results Small differences
If differences, please give a brief description of the results of this comparison.

Area under wine grapes is 10% larger in vineyard statistics 2015 than in the previous vineyard statistics of years 2009 and 2013, and 3% smaller than in Annual Agricultural Survey 2013 (see also additional comments).

 


Additional comments

Comparisons between the various sources and the register data were made for wine grapes excluding dual purpose grapes that are not included under wine grapes in the other data sources (FSS, ACS, previous vineyard surveys, Annual Agricultural Survey).

Regarding raisins, in Greece there are two raisins’ varieties Korintiaki (42% of the total area under raisins) and Soultanina (58% of the total area under raisins).  The main raisins variety Soultanina is a triple purpose variety. The part used for wine production is fairly clear. However the parts used as table grapes or raisins cannot be adequately distinguished. This results in differences between the various sources and since table grapes are not included in the current survey it is not possible to obtain meaningful comparisons.
