How can we reduce our water consumption?
We often think of reducing our water usage by doing things like taking shorter showers or turning off the sink while we brush our teeth. This is one way we consume water, called direct water use. However, we often overlook the other type of water consumption that can play an even bigger role in our water footprint: indirect water use. Indirect water use includes water used to produce the goods and services we consume daily. This includes the water used to manufacture our cells phones, harvest the cotton that is later used to make our clothing, and produce our food.
What is the water footprint of meat?
Red meat has one of the highest water food prints, with almost 680 gallons of water used to produce 6 ounces of steak. The high footprint for industrially-produced animal products comes from the water needed to grow food for the animals and sustain them until they are used to produce meat. Look for pasture-raised meat instead of industrially produced meat because much more water is used to make corn or soy feed than to have the animals graze grass. If you aren’t ready to cut meat out of your diet, start small with “Meatless Mondays” or opt for chicken instead (chicken has a lower water footprint).
What is the water footprint?
Water footprint (WF) is an indicator of the volume of freshwater resource consumption that incorporates direct and indirect water use. Global freshwater resources are prone to detriment due to water consumption in agriculture. Wheat production contributes considerably to the global water consumption burden. A life cycle assessment-based WF analysis of wheat production was conducted to quantify the water consumption during the entire life cycle of wheat systematically and scientifically. We quantified the temporal distribution of WF of wheat production in Shandong Province, China, from 2009 to 2015 and analyzed the spatial distribution of direct WF of wheat production in 2015. Soil testing and an on-site survey were conducted to examine fertilization overuse. Results showed that gray WF accounted for the largest proportion (nearly 46%), followed by green and blue WFs. Gray WF was mainly from aquatic eutrophication (over 96%), and its key substances were chemical oxygen demand and total phosphorus. Direct water consumption, direct emissions, fertilizer use, and diesel consumption exhibited high potential impacts. This study indicated that rational fertilization on the basis of the soil testing, improving the diesel consumption efficiency, and wheat straw returning to fields have great potential for intensifying water resource management.
Why is water footprint important in Morocco?
A water footprint assessment is not an appropriate guide for allocating water efficiently in water-scarce regions such as Morocco. Water footprints contain too little information to identify policies or investments that will achieve public goals regarding agriculture, natural resources and livelihoods. In fact, they would impair efforts to enhance food security and sustain economic growth. The better way forward for Morocco and other countries is to analyze the full range of economic, social and environmental issues pertaining to water use in agriculture and other sectors.
How do pesticides affect water?
Pesticides are another agricultural product which can impact on water resources. Water that goes into drinking water supply should be mostly free from pesticide residue; however as the use of these chemicals increases with excessive farming, protecting drinking water sources can be difficult and require extra measures.
Is water a part of agriculture?
Both water and agriculture are essential for life. Society cannot function without a secure source of affordable food products, and without a reliable source of water it is impossible for agriculture to operate properly. In spite of this, the agricultural sector is regarded as one of the world’s worst polluters ( the Foundation for Water Research ).

How does agriculture affect water?
In short, agriculture has a significant impact on water resources; and while people’s individual water footprints will never approach zero, the more meat, dairy and processed foods each of us consumes, the more water we use and the higher our water footprints.
How to calculate water footprint?
Water footprints were developed by the Water Footprint Network to assess the amount of water (in different types) that is consumed in producing food and other products. Water footprints are composed of three separate calculations: 1 1 Blue Water Footprint: The amount of surface water and groundwater required (evaporated or used directly) to produce an item. For food, this refers mainly to crop irrigation. 2 Green Water Footprint: The amount of rainwater required (evaporated or used directly) to make an item. For food, this refers to dry farming where crops receive only rainwater. 3 Grey Water Footprint: The amount of fresh water required to dilute pollutants and make water pure enough to meet EPA water quality standards. For food, the water would have become polluted from agricultural runoff or leaching from the soil.
