The Potential of Hydroponics to Reduce Global Hunger

The Potential of Hydroponics to Reduce Global Hunger


The world population is expected to reach 9.7 billion by 2050, and it is estimated that we will need to produce 70% more food than we currently do to feed those people. To solve this problem, the world needs a new way of producing food quickly and efficiently.

Hydroponics is a method of growing plants without using soil, which can be done in a controlled environment with little water, sunlight, or space. This method of farming has been around for a long time but has been gaining traction recently due to its potential for increasing crop yields by up to 100%. This makes hydroponics an attractive solution for to feed large populations with little land available for farming.

What is Hydroponics?

Hydroponics is a type of farming that is done without soil. The plants grow in a soilless nutrient-enriched water solution. Hydroponics is also known as hydroculture or aquaculture.

Hydroponic Farming Methods

There are many different hydroponic methods and systems to choose from. The choice will depend on the type of plants you want to grow, the size of your garden and how much time you want to spend maintaining it. Some of the popular methods are: Deep Water Culture, Ebb and Flow, Nutrient Film Technique, and Drip method.  Read here for details.

Hydroponics requires less space than traditional gardening methods, less water and it produces more produce per square foot than soil-based agriculture methods.

How Hydroponics Can Help Reduce Hunger Globally

The world is continuously facing the problem of hunger. With a growing population and climate change, the issue is expected to worsen. There are several different solutions that have been proposed to reduce hunger globally but many of them are not sustainable or affordable. One solution that has been proposed is hydroponics because it is a sustainable way to grow food without the need for soil or sunlight.

Hydroponics can help reduce hunger globally by producing food in an efficient and affordable manner, with minimal land required for production, and without using pesticides or fertilizers. In this type of farming, water, nutrients, and minerals are supplied plant's roots instead of taking them up from the ground.

Research suggests that simplified hydroponics can reduce land dependency by 75% and water dependency by 90%. Further, hydroponic systems allow up to 90% efficient usage of water. Surprisingly, the modern hydroponic systems can produce up to 240 times more crops than traditional farming methods.

Other advantages of using hydroponics are:

  • Reduced loss of crops to drought, diseases, or global warming- Since hydroponics is a closed system, it is not affected by weather and other natural calamities.
  • Easy accessibility- Underdeveloped nations, developing nations, or other poorly developed regions of the world may have transport or food supply chain issues, hence hydroponics can act as localised farming system to sustain food supply and reduce dependency on transport. It was estimated that food insecurity increased by 40% in Africa in 2020, however using hydroponics, almost 6000 tons of crops have been produced to reduce hunger and malnutrition in Africa.

  • More protein- Protein is the main nutrient for human development and sustenance. Plant based protein sources such as peas, beans and other legumes are now being grown in hydroponic systems to meet the growing protein demands. Read more here.


Hydroponics is a technology that can help reduce hunger. It has been proven to be more efficient than traditional farming in terms of water and land usage. Hydroponics also allows to produce food in places where it would not be possible to grow anything due to environmental or other barriers.
