Abstract
Assessing the Water Footprint of Irrigated Rice Production for Doho Rice Irrigation Scheme, Butaleja District, Uganda
Highlights
There is little awareness regarding the fact that the organization and characteristics of a production and supply chain strongly influence the volumes of water consumption and pollution that can be associated with a final consumer product. [3] have shown that visualizing the hidden water use behind products can help in understanding the global character of fresh water and in quantifying the effects of consumption and trade on water resources use
The green water footprint was higher than that of the blue water footprint. this means that rain water was more used than the irrigation water
Water footprint assessment accounts for the water consumed and the sustainability of water use
Summary
Instead of measuring the volume of agricultural water used, which traditionally only includes irrigation water, the WF is an indicator measuring the volume of water used during the whole growing cycle at the point of production It quantifies the impact of natural endowment and climate factors on the agricultural water use efficiency, including natural factors, such as the latitude and longitude, soil types, climate factors like precipitation, maximum and minimum temperatures, etc [5]. This ratio can be used as an index of irrigation water rational use.
