Participants at UN Climate Talks are typically surrounded by discussions on a wide variety of climate impacts, climate solutions, and complex interactions. While it may seem like every issue is being discussed during numerous side panels and events, these same issues may not always be raised during the political side of the talks. Here, the focus often tends to rest on climate finance, Nationally Determined Contributions, adaptation/mitigation, and capacity building, with some topics such as gender and land use making an appearance.
One of the crucial issues not specifically included in this list is the energy-water nexus. It’s true that energy and water are woven into the issues discussed through technology, concerns for adaptation, and resilience, but energy-water nexus topics are often not independently discussed. The Paris Agreement states that without curbing emissions, there will be a massive concern for water resources, with Sustainable Development Goals (SDGs) 6 and 7 set to specifically address water concerns. Even with the Paris Agreement in place, there may be many concerns about water availability and water quality in the future. Energy is more frequently addressed because of its importance in reaching the emission reduction plan set forth, but this does not consider the interactions between energy and water resources, nor how they may be impacted by climate change.
At COP23— the 23rd Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC)— held this November in Bonn, Germany the issues of water and energy took more of a center stage:
- A themed Water Action Day focused around water and climate.
- Groups such as ADASA and the World Water Council spoke out about the importance of water and energy in the climate debate.
- A partnership event titled The Water-Energy Nexus: Promoting Equitable and Sustainable Use and Management of Water and Energy Resources for All addressed “the importance of maintaining ecosystem services when generating hydroelectric power link[ing] the conversation around implementation of the Paris Agreement and SDGs 6 and 7.”
The Global Climate Action (GCA) Initiative Media Briefing on Energy, Water and Agriculture stressed how everything that happens with climate, is linked to everything that happens with energy, is linked to everything that happens with water! Even a slight inefficiency in one area could lead to catastrophic impacts for the whole interaction.
As was aptly stated by René Castro, Assistant-Director General of the UN Food and Agriculture Organization (FAO), “There is no room for inefficiency.”
Paulo Bretas de Almeida Salles, President of ADASA in Brazil (a regulatory agency for water and sanitation) presented concerns about water resources,
“There is a traditional idea that we have lots of water, that water is an infinite resource- now we are learning that this is not true.”
He also voiced the unmistakable connection that,
“Water and climate change are directly related… Everything that happens on earth based on climate has some relationship with water.”
In panel discussions, negotiators stressed how we need water to be able to provide and produce the necessities for this world, and discussed the connection between energy and water being that it takes energy to produce clean water and water is often needed to produce energy.
In the GCA Media Briefing they offered a summary of information:
- Of total water use by humans, only 10% is safe drinking water; if even a small percentage of that water becomes unusable, there would be major impacts on availability worldwide.
- Agriculture, on the other hand, uses 70% of total water use! The fact that this is such a high percentage opens the door for new advances in technology and water reduction strategies that would improve the world’s water situation.
- One such technological advancement offers promise—renewable energy stands to use 20 times less water than conventional energy sources.
Both energy and water are resources with a history of being mismanaged, and both are resources that have a direct interaction with the forces of climate change. By including water and energy—both distinctly and as an interrelated force—in the discussion at COP23, new policies and guidelines can be established to more effectively manage these valuable resources and leverage them to our advantage in the fight against climate change.
