The Role of the Systems Approach for the Water – Food – Energy Nexus The role of the systems approach when dealing with the water, food, and energy nexus is to understand and depict the interconnections between all parts, to ensure the parts are divided equally, and that the sum of all parts equals the whole. By focusing on just one part, for instance water - trying to make the heating of water and the extraction of water better, you can actually be causing more issues at the expense of the energy sector. According to the Food and Agriculture Organization of the United Nations, “This (nexus approach) can help us to identify and manage trade-offs and to build synergies through our responses, allowing for more integrated and…show more content…
One notable energy source is biofuel. Biofuel is made from agricultural efforts. While this seems like a win/win for the energy industry, and the agricultural industry, it’s detrimental to the water industry. How? If you take a step back, you will see that the demand for fresh irrigation water is increased, so is the increase for pesticides and fertilizers. With unsustainable irrigation practices, water run-off, the lack of watershed management programs, and unpredictable climate changes and weather patterns, surface and ground waters are more susceptible to pollution and contamination. This is a reality that Lake Okeechobee knows all too well right now. Back pumping from sugar cane agricultural land into Lake Okeechobee has caused surface water contamination, and a call for a “state of emergency” for the lake and its water quality. Water and Energy Nexus of Providing Hot Water Since water isn’t naturally “hot”, it takes energy to get it to a desired heated temperature. There are different types of energy used to get water to a heated temperature: solar energy, electrical power, hydro-electrical power, etc. Knowing the linkage between what energy makes water heat up the fastest, yet is the cleanest would be the most desirable choice for the water-energy nexus in providing hot water. Ideally, to collect and store solar energy for water heating usage would solve two
