Sustainable food systems are food systems that allow both food production and consumption without damaging the environment. Therefore, for a sustainable system, sustainable ways of farming, such as employing cover crops and embracing agroforestry, are used. Besides, the secondary purpose of sustainable food systems is to reduce waste and spoilage.
On the other hand, sustainable energy systems’ primary objective is to decrease energy production’s effect on the environment. One practice to promote sustainable energy is using renewable sources such as the sun for fuel.
Read on to learn more about the emergence of sustainable food and energy systems.
- Sustainable Food Systems
A sustainable food system (SFS) is a food approach promoting food security through diversifying food sources. You can also achieve food security via SFS by subsidizing small-scale farmers. You can train them on sustainable farming techniques to increase food production. For instance, innovative food and energy approaches in soy production can make a great deal of difference. It can enhance the yield and bring better quality crops.
Over several decades, sustainable food systems have been developed to create environmentally sustainable and socially impartial food production. The purpose is to fit existing demands without interfering with the ability of future generations to meet their own.
Governments and organizations like the United Nations have been implementing sustainable food systems. Although improvement has been made towards sustainable food systems, continued steps are needed to ensure food security for all while minimizing adverse environmental and societal impacts.
- Examples of Sustainable Food Systems
Below are some examples of sustainable food systems;
- Urban agriculture
As the word implies, urban agriculture is the practice of farming in urban areas. In most cases, food crops are grown instead of cash crops. Food crops refer to crops locally for food and not for sale; cash crops refer to crops specially planted for purchase.
Urban farming illustrates sustainable food systems as it does not employ pesticides to control pests. Instead, it uses natural processes such as mulching to manage the weeds. Urban agriculture also optimizes the land available via farming methods such as vertical farming.
- Community-supported agriculture
Community-supported agriculture (CSA) is a sustainable food method where growers market straight to their customers. In this model, customers purchase an allocation of the yield in advance and receive regular deliveries of fresh produce throughout the growing season. The CSA model enables sustainable farming and permits farmers to secure a product market while supplying customers with fresh, organic produce.
Another illustration of a sustainable food system is agroforestry. Agroforestry is the farming of produce concurrently with trees. This farming method is vital as it enables food diversification by boosting soil fertility.
Growing trees together with crops is helpful, particularly in preventing soil erosion and retaining soil humidity. This is necessary as all the nutrients plants need to grow in the topsoil.
- Sustainable Energy Systems
Sustainable energy systems are all about finding ways to meet our energy needs without causing harm to the environment. This means using renewable energy sources like solar, wind, and hydroelectric power instead of relying on finite fossil fuels. Some benefits of using renewable sources for energy production include;
- Less Global Warming
Renewable sources such as the sun and wind cannot be replenished; therefore, they do not produce greenhouse gases. Greenhouse gases are gases such as carbon dioxide, which trap heat in the earth’s atmosphere. The production of these gases then leads to climate change causing the sea level to rise due to ice melting in high-altitude areas such as the mountains.
- Stable Energy Prices
Since renewable energy cannot be exhausted, costs will likely remain stable. For instance, when a wind turbine is installed, occasional ongoing costs are associated with generating energy from these sources. In comparison, traditional energy sources like coal and natural gas are subject to fluctuations in fuel prices, which can cause energy costs to be volatile. Besides, renewable energy sources are subject to different supply and demand limitations than fossil fuels.
Besides, renewable energy sources are subject to different supply and demand limitations than fossil fuels. Because the wind and sun are free and widely available, there is less risk of price volatility due to supply and demand constraints. This can help stabilize power costs over time as renewable energy sources become more widely embraced.
- Creation of Jobs
Sources of energy such as wind require wind turbines so that they can create power. Hence, an installation mechanic is needed to install the turbine and a mechanic to preserve the turbines. Similarly, you will need electricians to connect electricity to the building when installing a solar panel.
Renewable energy also creates job opportunities in manufacturing as supplies such as biogas digesters are made and installed. This also creates jobs in metalworking, machinery, and assembly. Moreover, the increasing demand for renewable energy may also usher in the development of new academic and training programs. Consequently, offering a path to new careers in the growing renewable energy industry.
- Interconnection between Sustainable Food and Energy Systems
Sustainable food and energy practices are interconnected in various ways, as they are necessary for achieving a sustainable future. For instance, the food system requires energy at every stage, from production and transportation to processing and allocation. Thus, much energy is needed to operate machinery and transport food items.
The food system likewise consumes a substantial amount of non-renewable energy, contributing to greenhouse gas emissions and climate change. Consequently, encouraging sustainable food production and consumption practices can reduce the energy demand of the food system and minimize its environmental impact.
On the contrary, sustainable energy systems can also contribute to sustainable food systems by supplying pure and inexpensive energy for food production and processing. Renewable energy sources, including solar and hydropower, can be harnessed to power food production. Thus, reducing dependence on fossil fuels and lowering greenhouse gas emissions.
Sustainable energy systems can also provide water pumping and irrigation fuel, vital for food production, especially in arid regions. Additionally, sustainable energy systems can enable the development of decentralized food systems where food is produced and consumed locally.
Sustainable food and energy systems are paramount when it comes to decreasing the effects of climate change—sustainable food production methods such as agroforestry aid in preventing soil erosion and retaining soil moisture. Agroforestry also satisfies climate change mitigation as trees help absorb the carbon dioxide in the atmosphere. Other techniques, such as urban farming, can help solve the food problem in urban neighborhoods.
Thus, using renewable energy, like solar energy, to produce power is indispensable for food production. This is because food production and processing need energy for heating and cooling. Hence, using energy from renewable sources helps reduce environmental pollution. This further means there will be less climate change, and future generations will not be affected.
