Final water demands in the template CLEW model This sector refers to self-supplied industries not connected to the public distribution network. Water used by industries connected to the network is included in commercial. Industrial sector water demand Interpreted as the result from the municipal water demand without the residential component. Data in AQUASTAT was aggregated to municipal. Water demand Commercial sector Water demand Residential Rural sector Water demand specific to the settlement type that originates from the daily average water consumption per capita. Residential Urban sector Water demand Water demand Environmental Flow Considered to represent 10% of the annual value of average precipitation. It is an assumption that can be manipulated.

Endogenous water demands in the template CLEW model Water demand that indirectly results from the amount of water involved in the evapotranspiration process. If a crop is rain-fed, it only uses water from precipitation. If a crop is irrigated, apart from precipitation, water is provided by surface and / or groundwater. Agricultural water demand Endogenous water demand Evapotranspiration precipitation Crop 1 Rainfed Ground Water Recharge Surface water pumping Crop 2 irrigated Runoff irrigation Groundwater pumping Summer School on Modelling Tools for Sustainable Development 12-30 June 2017, ICTP, Trieste.

Example Example - Water balance in a maize field Inputs Outputs Precipitation Groundwater Irrigation Runoff Evapo- transpiration Crop production Energy 27
Example Example Material flows in a maize field Let s take the example of 1 kha of irrigated corn field. During a period of one year, the farmer estimated the following flows on this piece of land. In terms of water inputs: 18.3 million m3 as precipitation and 5.4 million m3 as irrigation. In terms of water outputs 16.7 million m3 are lost as evapotranspiration, 3 million m3 to groundwater reservoirs and 4 million m3 as runoff. Energy requirements to operate various pieces of machinery include: 228 GJ of diesel, 24 GJ of gasoline and 25 GJ of LPG. Finally, the annual crop yield of this land amounts to 2,080 tonnes of maize. 28
