Assignment:1 Water-Energy-Food Nexus
Introduction
Human comfort relies upon the availability and wise management of food, energy and water, important to maintain the ecosystem which regulates the conditions for life (FAO, 2013). Normally, we consider energy, water and food as three different segments but actually they are all interlinked. Water is used for extraction, mining, processing, refining, and residue disposal of fossil fuels, as well as for growing feedstock for biofuels and for generating electricity. Energy is used to transportation of water and final products of agriculture. Food is used to generate bio fuel. Food production is the largest consumer of global fresh water supplies and more than one-quarter of the energy used globally is expended on food production and …show more content…
What strategies to improve water and energy efficiency can be developed out of this water-energy-food nexus? Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Water and energy are inter-related, where you need to understand the value of system thinking and focus on every day action. We can empower water and energy efficiency resource planning and related technologies. It is important to protect strategies through water and energy with regimes and institutions. As the world has changed we are depending on technology that makes the people more addicted to technology it is difficult for us to work on right choices among resource efficient knowledges. For example, we use heater in the bathroom to heat water and use them where the heater needs electricity. Typical domestic uses of hot water include cooking, cleaning. In industry, hot water and water heated to steam have many uses. Fossil fuels such as natural gas, liquefied petroleum gas, oil or solids fuel are commonly used for heating
