Aquastat data

Most of the data used in the water preprocessor comes from the AQUASTAT database. http://www.fao.org/nr/water/aquastat/main/index.stm 

The AQUASTAT database can be queried on-line and the query results can be downloaded in CSV (table or flat) format. The current database regroups data per 5-year period and shows for each variable the value for the most recent year during that period, if available. For example, if for the period 2003-2007 data are available for the year 2004 and for the year 2006, then the value for the year 2006 is shown. Also, for many variables no time series can be made available yet due to lack of sufficient data. Data collection began in 1958.

Data for the variable [4313] "Area equipped for irrigation: total" is collected by and available in both AQUASTAT and FAOSTAT and harmonization between AQUASTAT and FAOSTAT takes place on a regular basis to ensure consistency between the two. The difference between the two is that AQUASTAT only enters data for the year given in the reference, while FAOSTAT fills all years from 1961 onwards by inter- and extrapolation from the common data-points. Thus, time series on this variable can be found under FAOSTAT land, choosing the last variable in "items": Total area equipped for irrigation. For other non-water related time-series on food and agriculture see the FAOSTAT home page.

Metadata

Update Frequency

Varies by Main Database category and sub-category:

1. Geography and population category: Every year (through FAOSTAT for land use and population and undernourishment, World Bank for GDP, UNDP for HDI and GII).
2. Water resources category: These are long-term average annual values and therefore remain the same over the years. A comprehensive review had been undertaken in 2014.
3. Water use category and Irrigation and drainage development category: For Africa, Southern and Central America & Caribbean, and Asia: between 1 and 10 years, depending on data availability which is checked at least every 5 years for each country, and with a thorough update (full dataset) every 10 years together with the country profile update. For Europe, Northern America, Australia and New Zealand: depends on data availability from Eurostat and OECD.
4. Updates of data for some specific sub-categories are being done in collaboration with others, as and when data become available, such as: wastewater sub-category in collaboration with IWMI; conservation agriculture sub-category in collaboration with Conservation Agriculture expert groups; access to improved drinking water source sub-category data are provided by the WHO/UNICEF Joint Monitoring Programme for Water Supply and Sanitation.
5. Some of the variables are updated during major review exercises (see the other datasets below).

AquaStat Questionnaires and Guidelines

AQUASTAT uses questionnaires and prepares guidelines with detailed definitions and instructions, implements projects to strengthen national capacities, and holds workshops to clarify some of the more complex data concepts. Survey information is as follows:

To reach the above objective, it has been decided to proceed as follows, with two surveys:

• Every 5-10 years: a detailed global survey to prepare/update country profiles and regional syntheses. This document refers to this survey, which is prepared on the basis of a detailed questionnaire filled in at country level by national and regional experts, under the supervision of FAO/NRL.
• Every year: a small global survey to ensure regular updating of the existing country profiles, of key changes at country level, especially on the area equipped for irrigation and on the institutional and policy aspects. It is done by concerned institutions, which are willing to participate, and is managed in the regional and central offices of FAO.

The 5-10 year survey aims at preparing national country profiles in a homogeneous way. It ensures participation of national experts, in charge of the information collection and report drafting at the country level, and validation by FAO experts. The experts are provided with:

• A detailed questionnaire to be completed for each country at national level (and sub-national level for some variables) on the basis of existing available information
• Detailed guidelines for preparing a country profile and gathering qualitative information
• Explanatory notes and definitions to ensure consistency in the use of concepts and words and facilitate computation

Costs

Costs should be expressed in US$ (United States Dollars) in the questionnaire and country profiles. The conversion used to pass from the local currency to US$ should be the one that was valid in the year to which the value refers and should be indicated in the comments. 

Definitions

Definitions for every series can be found in this document: http://www.fao.org/nr/water/aquastat/sets/aq-5yr-guide_eng.pdf 

DataDict

Variable: Names were not changed from previous years this data was pulled. New variables were assigned names that are consistent with variables of similar topics.

Table: These were not changed from previous years this data was pulled. New variables were assigned based on the variable title and consistency.

Groups: These were not changed from previous years this data was pulled. New variables were assigned groups based on consistency with variables of similar topics. New Irrigation series were given groups: Agriculture, Infrastructure, Water. 

Subgroups: These were not changed form previoys years this data was pulled. New Irrigation data was given the Subgroup: Irrigation.

Definitions and Units: This categories were not changed from previous years. New variables were given definitions based on the consise definitions provided in the AquaStat database. Units were also provided in the data base.

Years: Years for every series were changed to available data provided through the database. Years vary between different series. The aquastat database calculates years in 5 year incriments. This five year incriments go back to 1958. The most recent incriment is 2013-2017. In the datadict, these incrimental periods are not used. Instead, only actual data recorded for the earliest specific year to the last specific year is used.

Source: Source for all AquaStat series were given AQU BATCH PULL.

Original Source: The original source for all series is the AquaStat database.

Notes and Last IFs Update were updated accordingly.

Aggregation: Aggregations were not changed from pervious updates. New variables were assigned aggregations based on the type of variable and the Units used.

Disaggregation was consistently GDP.

Name in source is based on the name each variable was given in the AquaStat database.

Code in Source: All codes were changed to match the exact variable names present when downloading the data from the database. The downloaded names were different from the name in source.

Decimal places: This category was left blank in order to avoid rounding exact data.

Country Concordance: FAO countries were used.

Instructions

1. Download the data from the Aquastat Database. http://www.fao.org/nr/water/aquastat/data/query/index.html?lang=en. Select all countries and all years. There are too many variables to download all variables at once. Divide the variables by topics (ie geography and population, water resources, etc) download this data via the "Flat" option.
2. Change the codes in the Datadict for every variable downloaded in this Excel file. The codes need to match to match the variables listed in the downloaded data exactly. 
3. Check to ensure no changes are needed in the FAO Country translation. In the most recent update China, Sudan and South Sudan all needed to be updated.
4. Upload data in IFs using the batch pool option. There will be multiple excel sheets, as the AquaStat data cannot download all variables at once. After the first excel sheet is updated, unselect data that was imported; otherwise this data will be uploaded again with a new excel sheet, and you will lose the already imported data.
5. Vet. The most recent update reveiled errors in data in some series. You may need extensive vetting.
6. Some series do not contain enough data in the database to be updated. These include:

LandIrEquipDesalinated

LandIrEquipDirectAg

LandIrHarvest%Equip
