Environment Statistics


Environment statistics concern many sub-sectors: water, waste, land use and land cover, air emissions and pollution, marine environment, biodiversity and sustainable development indicators.

In all GCC countries, the national statistics centres (NSCs) are the institutions responsible for the compilation and dissemination of Environment Statistics. Many national organisations (ministries, authorities, etc.) are responsible for the data collection and provide them to the NSCs. A close technical cooperation is in taking place between NSCs and these national organisations through national working groups. The present priority is given to water statistics.


Coverage and methodological issues

Most of the water flows required by international standards are compiled in a single data set divided in several tables according to water cycle: water resources, water abstraction, use and returns, wastewater generated and management, water quality and infrastructure.

For the water resources, the data collected for the precipitation, defined as the volume of water that flows from the atmosphere to inland water resources via rain, snow, sleet, hail, dew, mist, etc., per year, are usually provided in terms of height (i.e. mm) by meteorological institutes. Water statistics require this data in terms of volume (usually million cubic meter per year). For that, when data are available in mm only, the transformation to million cubic meter per year is derived as the multiplication of annual average of precipitation in mm at country level by the surface area of the country divided per 1000.

Concerning the second indicator, about rate of desalinated water production per capita (in litter per day). The desalinated water is defined in the FDES as the volume of water produced by an economic unit through the process of desalination, within the territory of reference, per year. This includes desalinated seawater and desalinated brackish waters from estuaries, rivers and aquifers.

The NSCs generally collect this data through national institutions responsible for water and electricity in charge of desalination plants.


Classifications and standards

Since the regional workshop on water statistics, GCC countries using the Framework for the Development of Environment Statistics (FDES) and the international Standards for Water Statistics (IRWS) as main standard for compiling data through the water transmission tables.



All GCC countries disseminate monthly precipitation statistics per stations, including number of days of rain. However, some countries disseminate the statistics only for one station or annually or in mm only.

Daily statistics on precipitation and others climate variables are disseminated to World Meteorological Organization.

For Desalination water production, the NSCs disseminate also monthly data.



All the GCC countries, through the national bodies in charge of meteorology and desalination, attach considerable importance to ensuring the accuracy of their data. However, the aggregated data in mm and million cubic meter are inconsistent in some countries. 


GCC-STAT and Regional Aggregates

The GCC Statistical Centre (GCC-STAT) collected data through NSCs websites, reports and GCC conferences presentation’s on same topic.  Then, the data was consolidated for all six countries in GCC water statistics database.
