The Future of Water: Can We Reduce The Water Footprint In Agriculture?
Every individual and institution consumes a certain amount of water through their daily activities. As unfortunate as it is, water is a finite resource. Therefore, it is essential to pay attention to water consumption not only on a personal level but also during production processes.
You might be wondering how we determine the amount of water used in producing a product or service. This is where the concept of the water footprint comes into play, developed to measure water consumption and raise awareness about the efficient use of water resources. Remember, the first step towards a sustainable world is increasing our awareness.
WHAT IS A WATER FOOTPRINT?
A water footprint is similar to a carbon footprint. While a carbon footprint measures the amount of greenhouse gases emitted into the atmosphere due to the activities of individuals and institutions, a water footprint measures the total water consumption involved in producing a product or service, from the production stage to the supply chain. This includes both direct water usage and indirect water usage during the production process.
In essence, the concept of a water footprint enables us to measure water usage across different areas such as domestic use, industrial production, and agriculture. This awareness allows us to take proactive measures to prevent excessive water consumption.
WATER FOOTPRINT IN PRODUCTION
One of the primary contributors to the increase of water footprint is production. The entire process of creating a product or service and delivering it to the consumer requires significant water resources. Ensuring the sustainability of freshwater resources involves not only raising awareness about water consumption but also maintaining efficient production practices.
So, what does the United States water footprint look like? Unfortunately, the data reveals a concerning scenario. After China and India, the United States has the third highest water footprint. Analyzing water consumption data by sector shows that a staggering 89% of the United States’ water footprint in production comes from the agriculture sector. Adopting sustainable practices in agricultural activities is crucial not only for the future of nature but also for securing our water resources.
THE IMPORTANCE OF WATER MANAGEMENT IN SUSTAINABLE AGRICULTURE
Efficient water usage is crucial for every sector engaged in production activities. However, it is especially important to emphasize water management in agricultural practices, which significantly contribute to the United States water footprint, to preserve the natural wealth provided by our environment.
So, what needs to be done? The answer lies in sustainable agriculture. Sustainable agricultural methods, designed to utilize production technologies that do not harm the environment, enable the conservation of natural resources and efficient water management in agricultural activities. By protecting the vital water resources that sustain nature, we can significantly reduce the high-water footprint in agriculture.
Remember, adopting sustainable agricultural methods is a step that must be taken not only for the future of production but also for the future of our planet. How can water management be achieved through sustainable agricultural practices? To answer this question, it is helpful to first examine the water resources considered in water footprint calculations.
WHAT SHOULD BE DONE TO REDUCE THE WATER FOOTPRINT?
The water footprint consists of three components: blue, green, and grey water footprints. The blue water footprint represents all surface and groundwater freshwater resources used in production, while the green water footprint refers to rainwater. The grey water footprint is an indicator of water pollution. Among these three components, the most consumed and crucial for the future of water is the blue water footprint which refers to natural freshwater resources.
Sustainable agricultural methods can reduce the blue water footprint by utilizing the other resources defined as green and grey water. For example, systems can be established to collect rainwater and use it efficiently for irrigation. Additionally, systems can be developed for the recycling of grey water to prevent it from becoming waste.
It is also essential to pay attention to irrigation systems in agricultural activities to avoid water wastage and protect crops from damage. Using appropriate irrigation methods such as drip or sprinkler irrigation can ensure more efficient use of water resources and maintain the quality of the crops. Thus, by taking steps to secure the future of water, we can preserve the quality and richness of the plants, which are nature's gifts to us, for future generations.
REDUCING WATER FOOTPRINT IN PRODUCTION
At Gaia Oliva, our commitment extends beyond providing high-quality products; we are also dedicated to the efficient use of natural resources. This is why we employ sustainable agricultural methods in our production processes. By doing so, we protect natural resources and produce without harming the environment. Wondering how? Let us explain.
Olive oil production methods are categorized into two types based on the oil separation systems: traditional pressing (batch) and continuous production. Continuous systems, which rely on centrifugation to extract the oil, can be either 2-phase or 3-phase.
In 3-phase production, olive oil, wastewater (black water), and pomace are produced. In 2-phase production, only wet pomace and olive oil are produced. Thus, 2-phase production uses less water and generates significantly less wastewater compared to 3-phase production.
