Water, a precious resource: how to preserve it with urban agriculture

Water, a precious resource: how to preserve it with urban agriculture

Water is a precious resource for life and the sustainability of our planet, but it is increasingly at risk. According to research from the World Resources Institute, 17% of the world's population lives in areas with high water stress, and it is estimated that this number could increase to 44% by 2050 without urgent changes by the community as a whole. Urban and vertical agriculture can play a crucial role in water conservation and promote sustainability, especially in urban areas where the majority of people live.

Growing gardens in cities, reducing the amount of water needed for irrigation is possible through the use of cultivation techniques such as hydroponics and aeroponics, which require less water compared to traditional agriculture. Let's discover how urban agriculture can contribute to more sustainable water management and how we can all do our part to protect this resource.

Vertical urban agriculture: a sustainable approach to cultivation

Urban and vertical agriculture is an innovative solution for growing food in cities, using less space and resources compared to traditional agriculture. This type of cultivation can help reduce environmental impact since it requires less water, energy, and transportation compared to traditional agriculture. Furthermore, urban agriculture can contribute to strengthening city resilience, improving food security, and reducing dependence on imports.

Hydroponic cultivation: an efficient irrigation method for water conservation

Hydroponic cultivation is an urban agriculture technique that allows plants to grow without soil, using nutrient solutions and water. This method is known to be more water-efficient than conventional agriculture because excess water can be easily recovered and reused. Additionally, hydroponic cultivation reduces the need for intensive irrigation, as plants receive the nutrients and water they need directly.

Rainwater harvesting: a sustainable alternative for domestic irrigation

Domestic rainwater harvesting is a sustainable practice that involves collecting and storing rainwater at home for irrigation. This technique can help reduce dependence on potable water and contribute to water conservation. By integrating rainwater harvesting into urban agriculture practices, green enthusiasts can do their part to preserve water and promote sustainability.

Circular economy: a holistic approach to resource preservation

The circular economy is an economic model aimed at reducing waste and inefficient resource use through reuse, recycling, and regeneration. This approach can also be applied to urban agriculture by reducing water waste, using recycled materials, and promoting sustainable practices. Green enthusiasts can contribute to the circular economy by adopting environmentally and water-friendly cultivation methods such as hydroponics and rainwater harvesting.

How to water your home garden without wasting water

If you're cultivating your home garden, you can also play a role in reducing water waste by adopting simple practices. You can choose to grow native or climate-adapted plants that require less water than exotic ones. Additionally, you can experiment with innovative cultivation techniques such as hydroponics, which use a reduced amount of water compared to traditional soil-based cultivation. Alternatively, you can collect rainwater using dedicated containers for harvesting rainwater from gutters or roofs. This way, you'll reduce the consumption of potable water for irrigation.

In general, the adoption of sustainable practices and the holistic approach of the circular economy can significantly contribute to preserving water as a limited resource, both in domestic and agricultural contexts.
