- Drip irrigation. Drip irrigation is the most efficient way to provide crops with the necessary water and nutrients for optimal growth. This method delivers water and nutrients directly to the root zone of each plant in precise amounts and at the right time.
- Capturing and storing water. Water harvesting and reuse systems are designed to collect and store runoff and stormwater, which can be used later for various purposes.
- Irrigation scheduling. Irrigation system managers use irrigation schedules to determine the appropriate frequency and duration of watering. Water management takes into account the method of irrigation, as well as the amount, timing, and frequency of water application.
- Crops resistant to drought. Farmers can enhance their crop productivity per unit of water by cultivating crops that are well-suited to the local climate.
- Drip Irrigation. Drip irrigation systems deliver water directly to a plant’s roots, reducing the evaporation that happens with spray watering systems.
- Capturing and Storing Water. Many farms rely on municipal water or wells (groundwater), while some have built their own ponds to capture and store rainfall for use throughout the year.
- Irrigation Scheduling. Smart water management is not just about how water is delivered but also when, how often, and how much. To avoid under- or overwatering their crops, farmers carefully monitor the weather forecast, as well as soil and plant moisture, and adapt their irrigation schedule to the current conditions.
- Drought-Tolerant Crops. Growing crops that are appropriate to the region’s climate is another way that farmers are getting more crop per drop. Crop species that are native to arid regions are naturally drought-tolerant, while other crop varieties have been selected over time for their low water needs.

Water scarcity is defined as the reduced availability of water due to physical shortage (for example, a drought), a lack of adequate infrastructure (such as channels and wells), or the failure of institutions to ensure a regular water supply. In other words, water scarcity occurs when there are insufficient water resources to satisfy the long-term ...
Today, water scarcity affects almost every continent: around 4 billion people live under conditions of severe water scarcity for at least one month of the year - nearly half of which live in India and China - and half a billion people in the world face severe water scarcity all year round.1Mekonnen et al. (2016). “Four billion people facing severe ...
Adding to the pressure on the world’s water resources, we will require an estimated 50% increase in agricultural production and a 15% increase in water withdrawals to feed a planet of 9 billion people by 2050.3WorldBank.org. Water in Agriculture. Accessed October 26th 2020.At the same time, rising average temperatures associated with changing clima...
All around the globe, scientists and researchers are working to develop intelligent solutions to reduce water scarcity. The European Institute of Innovation and Technology, for example, has launched an initiative to find solutions to water scarcity, with a particular focus on Southern Europe. Here are six smart solutions to reduce water use in agri...
While farmers use the latest technologies to avoid wasting water, we can also change our eating habits to reduce some of our water footprint. For example, we could reduce meat consumption (it takes a lot of water to produce meat!) and prefer foods with a lower water footprint. Avoiding food waste is also going to help avoid water waste – so a good ...
Jul 12, 2016 · Scientists have developed an approach to solving this: they got plants to use water more efficiently without restricting their growth. This is thanks to a plant-inherent water-conservation...
Oct 2, 2024 · Adopting water conservation techniques can help farmers optimize water usage and ensure crops receive adequate moisture while reducing wastage. Optimizing water usage enhances agricultural productivity, leading to increased yields and improving food security.
Jun 28, 2024 · Justification: Water-use efficiency (WUE) is the amount of carbon assimilated as biomass or grain produced per unit of water the crop uses, and it is considered a critical factor in maintaining the balance between carbon gain and water loss during photosynthesis, particularly in the face of global warming and drought challenges.
Jul 29, 2008 · Tools. Share. Abstract. [1] The competition for existing freshwater supplies will require a paradigmatic shift from maximizing productivity per unit of land area to maximizing productivity per unit of water consumed.
