2. Statistical presentation | ||||||
2.1 Data description | ||||||
The survey takes into consideration all enterprises which distribute pesticides in Italy, for each province, either under their own brand or foreign brands. The main variables surveyed are: quantity of pesticide product and quantity of the active substances (produced in Italy or imported) distributed with own trademark for only agricultural use, for each province. When the pesticides are imported, the enterprise can state the pesticides distributed with other trademark (if they haven’t their appropriate trademark). The term pesticide indicates those products containing or comprised of substances intended for various uses, including protecting plants or plant products from harmful organisms, destroying unwanted plants or parts of plants. The term active substances refers to all substances which exert a general or specific action against harmful organisms or on plants or parts of them. Phenomena investigated are: - sale of pesticides, per category (fungicide, insecticide and acaricides, herbicide, biological, other and insect traps), toxicity class and province (Nuts III level); - sale of the active substances authorised for the market. Biological products and traps were introduced in the survey, in order to complete the survey | ||||||

4. Quality management | ||||||
4.1 Quality assurance | ||||||
Since the 90s Istat adopted a systematic approach to ensure quality in both statistical information and service to the community. For this purpose, the Italian National Institute of Statistics has defined a quality policy providing itself with appropriate tools as well as management changes to carry it out. Istat quality policy is aimed at the improvement of statistical outputs and processes through the development of appropriate methodologies and tools as well as an appropriate scientific and technical support, provided to the personnel directly involved in the production and dissemination of statistical information. Istat quality policy is coherent with the European framework developed by Eurostat, taking up its main principles and definitions stated in the European Statistics Code of Practice and useful to ensure and strengthen the accountability and governance of the European Statistical System and of the National Statistical Systems. For details: https://www.istat.it/en/organisation-and-activity/institutional-activities/quality-commitment | ||||||
4.2 Quality management - assessment | ||||||
Surveys on sales have been conducted in Istat for several years and the content is very detailed in terms of information on pesticides and in terms of geographical detail. The survey is included in the National Statistical Programme. It is a census based survey conducted every year. | ||||||
5. Relevance | ||||||
5.1 Relevance - User Needs | ||||||
Main data users: Ministry of Agriculture, Ministry of Heath, The Institute for Environmental Protection and Research, ISPRA (Istituto Superiore per la Protezione e la Ricerca Ambientale). For example, ISPRA uses the data to produce the national report on the presence of pesticides in water that provides information on on the risks due ti the presence of these substances in water. | ||||||
5.2 Relevance - User Satisfaction | ||||||
Istat is constantly interested in understanding who the users of the statistics it produces are, what the information needs are, whether they match production and if the statistics produced satisfy users. To this aim, together with the analysis of user requests received through the Web Contact Center service, tools for direct consultation were developed, such as the annual online survey of customer satisfaction and indirect tools such as analysis of accesses and of users' browsing paths on the web site. We do not measure user satisfaction for this survey. | ||||||

11. Confidentiality | ||||||
11.1 Confidentiality - policy | ||||||
Several national legal acts guarantee the confidentiality of data requested for statistical purposes.
According to art. 9, paragraph 1 of the Legislative Decree n. 322 of 1989, personal data cannot be disseminated but in aggregated form, in order to make it impossible to make any reference to identifiable individuals. They can only be used for statistical purposes.
Legislative Decree n. 322 of 1989, art. 6 bis and Legislative Decree n. 196 of 2003 Annex A3 (Code of conduct and professional practice applying to the processing of personal data for statistical and scientific research purposes within the framework of the national statistical system), art. 8, provide that the exchange of personal data within the National Statistical System (Sistan) is possible if it is necessary to fulfil requirements provided by the National Statistical Programme or to allow the pursuit of institutional purposes. The supply of the identification data of statistical units is allowed within the framework of entities included in the National Statistical System if the requesting party declares that no identical statistical result can be obtained otherwise .
Regarding subjects who do not belong to Sistan, Article. 7 of the Code of conduct (Decree n. 196/2003, Annex A3) states that it is possible to transmit individual data files without direct identifiers within the framework of specific laboratories set up by entities included in the National Statistical System, under certain conditions and only if that the data are protected by the application of different statistical methods that make it highly unlikely the identification of statistical units. | ||||||
