Agriculture looks set to remain the biggest user of water into the middle of this century. and over 1 Mio. According to a 2012 study, “A Global Assessment of the Water Footprint of Farm Animal Products,” by Mesfin M. Mekonnen and Arjen Y. Hoekstra of the University of Twente in the Netherlands, “The total water footprint of animal production constitutes 29% of the water footprint of total agricultural production,” with one-third of that water being used to raise beef cattle. , Chenoweth J., Chapagain A., Orr S., Antón A., Clift R. Morand-Fehr Nonetheless, the methods mentioned in this paragraph may decrease water intake by animals only slightly. In the US, it remains the main source of pollution of drinking water reservoirs [4].In a 2013 study, three dozen environmental scientists undertook an ambitious task of identifying the harmful effects of agricultural runoff across the U.S. in order to understand and help manage it better [4].. (2011) estimated weighted blue water use as 61 L, of which 75% arose from on-farm forage irrigation. A second difference is whether water use is reported as a volume of water or as an index of water-use impact (e.g., H2O equivalents). Blue and green water are thus closely interwoven. Final estimates from the ABS' annual agricultural survey are available each year in this publication (Water Use on Australian Farms) as well as in a number of other ABS publications. In agriculture, water must be of Statista assumes no Mtg. Water-mediated ecological consequences of intensification and expansion of livestock production. For example, when early-stage fresh grass is fed, animals do not require drinking water. (1997), who reported 200,000 L/kg of beef, did not specify the method used, but the calculation was based on extensive rangeland systems, which require a large area for animal production. Land use changes can also significantly contribute to climate change. If green water is included in estimates (as in water footprints), the total water used by low-producing animals in pastoral rangelands, such as those in arid plains or high mountains, would be extremely high. A. Y. Réduire la vulnérabilité de l'agriculture à un risque accru de manque d'eau, Intergovernmental Panel on Climate Change (IPCC). Global Water Outlook to 2025: Averting an Impending Crisis, A Report. use, it is clear that globally, industry uses only a fraction of the amount of water used by agriculture. It indicated that 1 334 562 ha or 1.1% of South Africa’s land surface was actively irrigated during 2014/15. Agricultural water is used for irrigation, pesticide External and fertilizer applications External , crop cooling (for example, light irrigation), and frost control. Decreasing the contribution of livestock to water scarcity can be achieved by decreasing feed irrigation. Despite these possible improvements, it is noteworthy that the green water content of grasslands and crops used for animals lies in the same range as that of crops used for human food or biofuels. Improvements in livestock management, such as croplivestock integration with the use of crop by-products by livestock, have been proposed (Food and Agriculture Organization of the United Nations, 2006; van Breugel et al., 2010). Industrial or intensive agriculture is distinguished from traditional agriculture by a high ratio of inputs to land area, and is also characterized by a reduction in fallow periods, in order to maximize crop yields. Some of the crops that require the most water … These differences are mainly due to characteristics of the production systems (i.e., an organic system without irrigation vs. a more intensive system with irrigation), and significant between-year differences were observed. Globally, about 40% of irrigation water is supplied from groundwater and in India it is expected to be over 50%. Water is used for household use, transportation, farming, and generating electricity. And this directly affects agricultural water use in California. Eur. A third is whether water that returns to the same location (e.g., in urine) is considered to have been consumed. Aubin In this guide we look at how much water the different sectors and industries use worldwide, and also in specific countries. When less extreme cases are considered, between-country differences exist, for example, ranging from 11,000 L/kg of beef in Japan to 37,800 L/kg of beef in Mexico. Rep. Ser. L. Total green and blue water use per kilogram of animal product1. Global water demand is expected to increase greatly in the future, by 50% between 1995 and 2025 (United Nations Environment Programme, 2008), especially in developing countries, not only because of larger human populations, but also because of overall increases in industrial production and human affluence, which lead to greater consumption of energy, consumer goods, and food, especially animal products. Sep 14, 2020 | Agriculture Water security is becoming an increasingly problematic issue worldwide. Additionally, water use may be more detrimental in one region compared with another, depending on the level of water stress in each region (Figure 3). Find Out The supply side of freshwater is a function not only of regional rainfall, which can vary greatly within and between years, but also water management and distribution systems and water pollution, which renders freshwater nonpotable. , Pfister S. Ridoutt Agriculture is a water-intensive practice, which is a concern for US regions that have increasing drought risk. Find out how we use water exactly and why conserving it is key. (2012) for 6 Australian beef systems, which correspond to blue water use, weighted by water-stress indices, ranging from 3 to 221 L/kg of body weight of beef. Direct water intake by animals is composed of drinking water, water contained in feeds, and a small amount of metabolic water produced by nutrient metabolism. But how much water is needed to produce it? Directly accessible data for 170 industries from 50 countries Although the debate on the consumption of animal products in developed countries remains open, the interaction between livestock and water resources should be considered with the objective of establishing sustainable farming systems. The major uncertainties – and explanation for discrepancies – in these assessments is the allocation of ‘rangelands’: in some regions it can be difficult to accurately quantify how much of rangelands are used for grazing, and how much is free from human pressure. Similar ranges (25 to 234 L/kg of body weight of beef) were observed by Ridoutt et al. If this value is considered, the total water used to produce the 60 million tons of beef every year is greater than the total freshwater reserves of the planet. In any case, the conceptual chain from estimating water use to estimating its potential impact is not built explicitly into the water footprint concept. For example, corn, which is widely used for livestock feeding, is highly sensitive to water scarcity, requiring irrigation for maximum biomass production when rainfall is insufficient. The variation probably arises from differences in local evapotranspiration, production systems, and animal productivity. This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (, Red meat—an essential partner to reduce global greenhouse gas emissions, About the American Society of Animal Science. Water Footprints of Nations. For ruminants, total water intake is generally between 3.5 and 5.5 L/kg of dry matter intake in temperate countries; it is greater for dairy cows than for growing animals or animals at maintenance. Although this permits multiple interpretations about impacts to be made by those who understand water resource management well, it leaves determination of the potential impacts associated with water footprints open to uncertainty and misinterpretation by those who do not. Overview and forecasts on trending topics, Key figures and rankings about brands and companies, Consumer insights and preferences in various industries, Detailed information about political and social topics, All key figures about regions and countries, Everything you need to know about Consumer Goods, Identify market potentials of the digital future, Technology Market Outlook Worldwide, agriculture represents 70% of total blue water use and 86% of blue + green water use (World Water Assessment Programme, 2009), whereas livestock farming uses 15% of the evapotranspiration of irrigated crops, 33% of that of rain-grown crops, and 68% of that of permanent pastures and rangelands . Gray water, a theoretical estimate of the amount of water necessary to dilute pollutants, varies widely depending on the pollutant (e.g., nitrate, synthetic organic chemicals) and the thresholds selected for their concentrations. Slaughtering just one animal can use up to 132 gallons of water. Ultimately, water scarcity depends on blue water use. Unfortunately, global climate change is modifying the supply side of the equation (rainfall patterns), and not in a uniform manner. United Nations Environment Programme, 2008, Organisation for Economic Co-operation and Development, 2004, International Organization for Standardization, 2006, Food and Agriculture Organization of the United Nations, 2009, Food and Agriculture Organization of the United Nations, 2006, http://www.inra.fr/l_institut/expertise/expertises_realisees/secheresse_et_agriculture_rapport_d_expertise, http://www.ipcc.ch/publications_and_data/ar4/wg1/en/contents.html, http://www.grida.no/publications/vg/water2/, http://www.fao.org/nr/water/docs/escarcity.pdf, http://creativecommons.org/licenses/by-nc/4.0/, Receive exclusive offers and updates from Oxford Academic, Copyright © 2020 American Society of Animal Science. Globally, agriculture accounts for 92% of the global freshwater footprint; 29% of the water in agriculture is directly or indirectly used for animal production . Agriculture: A $2.4 Trillion Industry Worth Protecting. Although such arid and semiarid regions are the most vulnerable to water scarcity, the demand side of the equation can have a strong, if not stronger, influence. In conclusion, total water outflow indicates the influence of agriculture on the global water cycle and highlights the role of water in ecosystems, whereas blue water use has an impact on water depletion. Res. We need food and we need clean freshwater to produce our food. Impacts et services environnementaux de l'élevage en régions chaudes. Most LCA approaches consider that green water is partially or entirely addressed by the impact indicator for land occupation (considering that soil water, like sunlight or oxygen, is an inherent property of land). Livestock water use and productivity in the Nile Basin. B. G. today. This is likely to decrease to 83.3% by 2025. Knowing how much water livestock species consume directly in food and drinking water is one indicator of their water use, but a more comprehensive indicator comes from estimating how much water was used on or before livestock farms to grow and process their feed or forage and after farms to transform them or their output (e.g., milk, eggs, fleece) into marketable products. Soil erosion by water, wind and tillage affects both agriculture and the natural environment. Worldwide, agriculture represents 70% of total blue water use and 86% of blue + green water use (World Water Assessment Programme, 2009), whereas livestock farming uses 15% of the evapotranspiration of irrigated crops, 33% of that of rain-grown crops, and 68% of that of permanent pastures and rangelands (FAO, 2006). P. We use the outcomes of that study to show general trends in the WFs of poultry, pork and beef. able water resources globally, this fraction is much higher—up to 80–90%—in many arid and semiarid river basins where water is scarce. One main difference among all methods for assessing water use is whether and how they include green and gray water. The water footprint of a nation is the amount of water used to produce the goods and services consumed by the inhabitants of that nation. Now, Kerlink , a specialist in solutions dedicated to the Internet of Things (IoT), and Sensoterra , a specialist in wireless soil-moisture-sensor solutions, have announced a partnership to take care of water waste. However, we recommend a holistic approach, in which the role of livestock in human societies is evaluated as a whole instead of considering the effect on water alone. The green, blue and grey water footprint of farm animals and animal products. The same pattern holds for total use of other resources, such as fossil energy, phosphorus, or land. B. G. Another possibility is to replace corn with other cereals, although their nutritional characteristics (e.g., amino acid composition) may differ. There are several means to decrease water intake. Irrigation provides approximately 40% of the world’s food, from an estimated 20% of agricultural land, or about 300 million hectares globally. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. Climate Change 2007: Working Group I: The Physical Science Basis. data than referenced in the text. With sustainability becoming or already representing a keystone of resource management and policy in many regions, it is necessary to consider how water use for livestock production influences water scarcity. This includes all nonagricultural activities, including industry, services, and domestic purposes, as well as some agricultural activities, such as crop irrigation, livestock drinking water use, use in factories producing inputs (e.g., seeds, fertilizers, animal feeds), or those producing animal products (e.g., dairy factories, slaughterhouses, tanneries). Water scarcity, a function of supply and demand, is a regional issue with global repercussions, given that 1) the increasing human population and demand for animal products will increase water demand and influence international trade in agricultural products and that 2) global climate change is altering rainfall patterns worldwide. 1: Drivers, Consequences, and Responses. The Department of Agriculture, Water and the Environment is responsible for policy and programs that support a globally competitive and sustainable Australian food industry. One third of this volume is for the beef cattle sector; another 19% for the dairy cattle sector. Research to develop indicators that inherently represent environmental impacts of water use has flourished in the past few years, specifically in the framework of life cycle assessment (LCA). Up to 70 % of the water we take from rivers and groundwater goes into irrigation, about 10% is used in domestic applications and 20% in industry. Zebus drinking at a reservoir in the Garissa region (northern Kenya). Life cycle assessment approaches tend either to exclude green water (considering that the evapotranspiration of soil water by crops has no more impact than that by the vegetation they replaced) or to include only the variation in green water attributable to changes in land use (e.g., from pasture to cropland; e.g., de Boer et al., 2011). 4 Agriculture is also a major source of water pollution from nutrients, pesticides and other wastewater and sewage industry in the U.S. importance of water in the global economy. October 7, 2015 Economic Development Over one billion people worldwide work in agriculture generating $2.4 trillion for the global economy. All LCA approaches include on-farm water used for irrigation, drinking water, and animal servicing (e.g., cleaning out buildings). . V. Globally, 70% of Freshwater is Used for Agriculture. M. W. The charts show the global average water footprint/requirement for the production of one tonne of product (in cubic metres); per kilocalorie (per litre); and per gram of … Globally, the largest water use happens in agriculture sector, primarily for irrigation. The 2 main options include decreasing the amount of irrigated feeds and reducing water intake by animals. Animal agriculture puts a heavy strain on many of the Earth’s finite land, water and energy resources. Slaughtering just one animal can use up to 132 gallons of water . Despite a huge variability in estimates according to the method used, it is clear that blue water use is the best criterion for estimating the contribution of livestock to the risk of water scarcity. Agriculture Meat’s large water footprint: why raising livestock and poultry for meat is so resource-intensive Kai Olson-Sawyer December 16, 2013 0 Surprise and disbelief. For the same region, total water uses for beef depend greatly on the production system. If we compare water use (i.e. , Wiedemann S. G., Rowley H. V., Tucker R. W. Pimentel A. Y. Irrigation increases human food security in many countries, but may deplete groundwater and, in extreme cases, lower water levels of inland seas and increase their salinity. That’s what often follows when people learn about the .) Anim. Blue water represents surface and groundwater, whereas green water represents water lost from soils by evaporation and transpiration from plants derived directly from rainfall (Falkenmark, 2003). In arid zones, the use of draft animals for drilling, hydraulic works, water extraction, and transport supports human settlements (Blanfort et al., 2011). After all, we have an abundance of rivers, lakes, and even three oceans, and we’re home to the largest fresh water lakes in the world. Australia is just one example of a country with a water withdrawal share that mirrors this % share almost exactly. Approximately 3.8tn cubic metres of water is used by humans annually with 70% being consumed by the global agriculture sector. household water use makes up approximately 22% of our country’s total water use, compared to an average of 10% worldwide. (2010) calculated a modified water footprint by excluding green water from pastures (but not for harvested forages) with grazing-based systems, in particular because grazing systems provide ecosystem services (e.g., grassland biodiversity support) and because there is often no alternative use for grazed grasslands. Food and agriculture are the largest consumers of water, requiring one hundred times more than we use for personal needs. Vol. Because freshwater availability depends greatly on geographic location (Figure 4), water use should be calculated for a specific area, either per hectare or per kilogram of product within that area. Globally, 70 percent of water withdrawals are used for agriculture. Overuse of water also has negative impacts on land, ecosystems and the economy. Some convergence in methodology has already occurred among LCA approaches, but certain differences remain. Livestock farming also has positive impacts on the environment related to water use. In contrast, because beef meat is the only product of a beef herd, the calculation of total water use of 1 kg of beef includes the water use by both bulls and steers, but also that of nursing cows. org/10.1016/j.jclepro.2011.10.027, The water footprint of dairy products: Case study involving skim milk powder. At the global scale, when total water use is expressed per kilograms of product, crop products almost always have less use than animal products (Hoekstra and Chapagain, 2007). What country uses the most water per capita? Furthermore, a third of worldwide grain production is used to feed livestock. Animal agriculture puts a heavy strain on many of the Earth’s finite land, water and energy resources. Vegan households use less than a third of the water of the average Australian household. Coping with Water Scarcity: Challenge of the 21st Century. Climate change, water and food security. This statistic shows the water consumption by country. , Doreau M. Peters Water evaporated from one location generally returns to the surface as rainfall at another location. For example, we don’t usually associate slaughtering animals with water consumption, but we should. Life cycle assessment is an internationally standardized approach for estimating the environmental impacts (in multiple impact categories) of goods and services throughout their life cycle, from extraction of raw materials and production to (in the most complete studies) their use and disposal (International Organization for Standardization, 2006). In contrast, few LCA approaches include gray water, most considering that it is already addressed in the LCA impact indicators for aquatic toxicity (related to pesticide and heavy-metal emissions) and potential eutrophication (related to nitrate and phosphate emissions, among others). The absence of blue water is due to the estimation method, which does not account for uses besides direct use by animals and the feeds they consumed. The U.S. Department of Agriculture (USDA) regulates agricultural producers to minimize water quality and quantity issues by using best management practices. Quick Analysis with our professional Research Service: Content Marketing & Information Design for your projects: In the following 6 chapters, you will quickly find the {amountStatistics} most important statistics relating to "Global water Industry". Irrigation of a sunflower crop in France (source: © 2007 iStockphoto.com/Donald Gruener). G. M. Impacts of drought are evident in agricultural activity estimates for the 2018-19 reference year across a number of the ABS' agricultural collections, including Water Use on Australian Farms. For example, the use of green water does not have the same impact on competitive blue water resources in a river system as the direct consumption of blue water has. That matters because the water doesn’t just appear – it has to be pumped in and out of the slaughterhouse. These indicators, oriented toward estimating total water use by-products, are useful for tallying international trade in virtual water and discussing the use of volumes of blue, green, and gray water in water resource management. Direct use of water for agriculture in Germany is almost negligible (just 0.3 km³ per year nationwide). Livestock farming plays a major role in many communities, especially for smallholders in developing countries. Agriculture cannot be ignored in the water equation, said Gerald Galloway, a civil engineer and visiting scholar with the U.S. Army Corps of Engineers. The hidden water resource use behind meat and dairy, Water footprints of nations: Water use by people as a function of their consumption pattern. As a theoretical amount of water, gray water does not influence water scarcity. Third United Nations World Water Development Report. A clean and plentiful water supply is essential for productive agriculture to supply the public with adequate food and fiber. In addition, developed and high income countries tend to use more water for energy generation and industry, whilst developing and lower income countries tend to use more water for agriculture. Blue, Green, or Gray Water: Which One Is Critical to Calculate Water Use? , Chapagain A. K. Hoekstra More than three-quarters of this is used for livestock production, despite meat and dairy making up a much smaller share of the world’s protein and calorie supply. Several solutions have been proposed to reduce corn irrigation. Some breeds adapted to drought, such as goats and camels, consume less water because of better water recycling. Environmental impact associated with freshwater use along the life cycle of animal products. More than 1 billion people depend on livestock farming, and animal products are an essential component of human diets. Agriculture is the science and art of cultivating plants and livestock. As for impact indicators, all LCA approaches define midpoint indicators of water-use impact. Agriculture is an industry that uses a large amount of water. P. ISO 14044: Environmental management—Life cycle assessment—Principles and framework. For the 2018-19 reference period, there are two When rainfall exceeds evapotranspiration, excess water infiltrates into the groundwater and runs off into rivers and then oceans, where it evaporates. , Hoving I. E., Vellinga T. V. Deutsch Agriculture, forestry, and fishing, value added (current US$) from The World Bank: Data Learn how the World Bank Group is helping countries with COVID-19 (coronavirus). Recent studies have highlighted the large amounts of water used for agriculture, especially for livestock production [e.g., Food and Agriculture Organization of the United Nations (FAO), 2006]. Similarly, Ridoutt et al. Access the. While the shift to biofuels is generally welcomed, their production could demand as much water as fossil fuels. As with most agricultural LCA, most existing studies stop at the farm gate, some continue to the slaughterhouse or food-processing factory, and at least one continues to the end consumer. 2000. I. J. M. (2010) estimated weighted blue water use of milk solids as 108 and 14 L/kg (i.e., approximately 830 and 108 L/kg of milk, respectively). For the remaining 36%, especially those living in temperate zones, livestock farming could be performed without strong water restrictions. Paris, France, and Earthscan, London, UK. It is likely that the growing idea in developed countries that animal-product consumption should decrease will not influence this trend. Because food sovereignty should be a target for each country, an increase in animal productivity can be an objective; however, this is often difficult to achieve because of environmental, social, and economic constraints. The Water Footprint Assessment Manual: Setting the Global Standard. As per the Central Water Commission, 85.3% of the total water consumed was for agriculture in the year 2000. A. K. For pastures with similar evapotranspiration per hectare, if animal productivity (e.g., daily body weight gain) is divided by 10 and grazing area per animal is multiplied by 10, the water footprint of the animal could increase 50 to 100 times, whereas the true impact of animals on water scarcity would be relatively low. We are happy to help. Motorized tankers allow water to be taken directly to animals, rather than vice versa (source: Bernard Faye; used with permission). All important statistics are prepared by our experts – available for direct download as PPT & PDF! Water use in industries Apart from human consumption, the importance of water in the global economy is evident - from agriculture, to manufacturing and industry, to the energy industry. Sécheresse et agriculture. Early-maturity varieties may be sown to synchronize maximal growth with freshwater availability, but their yields are less than those of normal varieties. Some LCA approaches also include endpoint indicators that estimate the impact on human health, ecosystem quality, or resource depletion (e.g., Milà I Canals et al., 2009). J. Areas suffering from water scarcity may change from year to year. Agriculture is the number-one user of water, accounting for 65% of total water consumed in Australia and 70% worldwide. Agriculture is the largest water user worldwide, accounting for 70 percent of total freshwater withdrawals on average 3 – but these amounts can reach as much as 95 percent in some developing countries. Vol. The history of agriculture began thousands of years ago. B. G. When the fact that roughly 55 billion animals are slaughtered each year is considered, this is truly astounding. The water footprint takes into account different types of water, including virtual water, but is limited to on-farm flows, whereas LCA is limited mainly to blue water but includes off-farm uses (e.g., “from cradle to farm gate”). Livestock water use is water associated with livestock watering, feedlots, dairy operations, and other on-farm needs. This text provides general information. Worldwide, agriculture accounts for 70% of all water consumption. The most important key figures provide you with a compact summary of the topic of "Global water Industry" and take you straight to the corresponding statistics. The “water footprint” approach includes green water, whereas life cycle assessment approaches tend to exclude green water or to include only the variation in green water resulting from changes in land use. Decreasing evapotranspiration (i.e., green water loss) is related to a decrease in photosynthesis and thus in biomass production because transpiration is related to carbon dioxide uptake, with both exchanges occurring through plant stomata. Both methods sum blue, green, and gray water use into a single indicator. , Herrero M., van de Steeg J., Peden D. Wiedemann among the various water use sectors in many river basins. Thus, water intake per kilogram of meat decreases when age at slaughter, and thus total feed intake, decreases, such as for chicken or for beef produced from culled dairy cows rather than from young beef cattle. Those pumps run on electricity, which runs on fossil fuels. By 2050, feeding a planet of 9 billion people will require an estimated 50 percent increase in agricultural production and a 15 percent increase in water withdrawals. This may happen even in regions with high rainfall, where population density and economic activity are high. Agriculture accounts for 92% of the freshwater footprint of humanity; almost one third relates to animal products. Get in touch with us.
