Farmers and their organizations are also often responding to highly distorted incentive frameworks in terms of water pricing and agricultural support policies , which further hinder positive developments in the sector.
Why is it important to protect agricultural water?
As a result, it is critical that farmers protect their agricultural water source to minimize the potential for contamination. As with any groundwater removal, users of irrigation water need to be careful in not pumping groundwater out of an aquifer faster than it is being recharged. Top of Page.

Why is water important for agriculture?
While water quantity is key to guarantee long-term sustainability and further determines which crops and which irrigation systems are most suitable given environmental (climate, soils, and landscape) and agricultural context, water quality has a significant influence on crop suitability.
How can agriculture save water?
Using agriculture water efficiently cannot only save water but also energy resources while improving yields. For this, understanding the local water resources is fundamental. For example, the type of water source determines the extraction method, which varies along surface water, groundwater or non-conventional water. The latter only provides one percent of agriculture water worldwide and includes treated wastewater and desalinated water, which is especially used in the Mediterranean, Middle East, and Andes regions, or on islands, and involves the use of specific technologies, which can also be run on renewable energy.
What will happen to agriculture in 2050?
By 2050 agriculture will remain an important determinant of economic growth, poverty reduction, and food security, despite the proportional decline of agricultural revenues in national gross income. Water use in agriculture will remain substantial, irrigated areas will expand and competition for water will increase in all sectors. Despite overall supplies of land and water will most likely be enough to achieve global food production goals in 2050, poverty and food insecurity will remain pressing challenges in several regions. While water will be sufficient to satisfy global food demand, an increasing number of regions will have to cope with growing water scarcity due to increasing competition. The outlook for 2050 provided by this paper reveals the demand for innovative and effective governance mechanisms to mitigate the impacts of growing water shortages. Investments in water technologies and infrastructure will be required for efficient water use, protecting food security and natural resources. Read more…

The Comprehensive Assessment of Water Management in agriculture is a critical evaluation of the benefits, costs, and impacts of the past 50 years of water development, the water management challenges communities face today, and the solutions people have developed around the world. This assessment describes key water-food-environment trends that influence our lives today and uses scenarios to explore the consequences of a range of potential investments. It aims to inform investors and policymakers about water and food choices considering such crucial influences as poverty, ecosystems, governance, and productivity. It covers rainfed agriculture, irrigation, groundwater, marginal-quality water, fisheries, livestock, rice, land, and river basins. Read more…
How does agriculture use water?
There are four main areas of water use in agriculture: growing of crops, supplying drinking water to livestock, cleaning farm buildings and animals, and supplying drinking water for those who work on the farm. The amount of each category varies according to the type of farm. For example, farms in the eastern part of North America usually receive enough rainfall and water from melting snow to meet most of the water needs. But drier areas, such as the U.S. and Canadian prairies, regions of Mexico, and some mountainous regions of the West do not receive sufficient natural moisture. On these farms, water must be supplied through irrigation.
How much freshwater is used for irrigation?
Nearly 60% of the world’s freshwater that is used by humans is used for irrigation. Of this water that is applied to crop fields, only about half returns to surface water or groundwater sources. The rest is lost by natural processes such as evaporation (when liquid water changes to water vapor) and transpiration (when water from plant leaves is transformed into water vapor), and accidental occurrences such as leakage from pipes or spillage.
Where Does Agricultural Water Come From?
Some of the water that farms use for irrigation comes from rivers and streams, either through surface or borehole extraction. This is largely because peak demands for agricultural irrigation exceed what the public mains supply can provide.
The Importance of Good Water Quality
Effective and safe uses of water in agriculture result in good crop yields and livestock production. But poor quality of water can have a significant negative impact on crop growing, animal welfare and health, and, ultimately, economic performance.
Water for Livestock

Ironically, according to Bruinsma (2003), there appeared to occur a change in diet preference towards meat and animal-based products. The amount of meat consumption in developing countries increased by about 124% from 11.4 kg during the mid-1970s to 25.5 kg per capita in 1997/99 (mean of 3 years is considered).
Uses of Water Amid Human Population Surge
Increasing the area of irrigated lands is a logical strategy to increase food production through agriculture in view of the projected increase in the human population ( about 2.4 billion more from 2010 to 2050 ). As already stated, statistics show that irrigation increases farm yields annually and per unit area of land.
What is the use of water in agriculture?
A large percentage of water is used in agriculture annually. Agriculture requires large quantities of water to grow fresh produce and sustain livestock. It is used for irrigation, pesticide and fertilizer application, frost control and crop cooling.

What is the water cycle?
The water cycle is a phenomenon where the water vapor created from oceans, lakes, and rivers condenses and returns to the earth through precipitation. The cycle includes evaporation, precipitation, and runoff as the transfer processes. Ponds, lakes, rivers, streams, and seas are some of the sources of water which depend on rains and water cycle.
Why is water important in power plants?
Power plants need a significant amount of water for cooling. Water is a universal solvent and hence is used to dissolve several compounds in industrial production.
Why do we need water?
Human beings need water for hydration as we regularly lose water during breathing, sweating and digestion. The amount of water that is needed depends on the climate, kind of physical activity and health status of the individual. Other living beings are equally dependent on water for their survival.
Why is waterborne disease important?
Contamination of water with pathogens is an important concern in the healthcare setting as the immune system is weakened in some patients. Waterborne disease can spread through direct contact, ingestion, in-direct contact, and inhalation, aspiration of water and blood contact.
