Nuclear Science Meeting Sustainability

As the global population continues to swell and pressures on natural resources escalate, thanks in part to increased demand and climate change; governments, industry and academia are looking to science for solutions.

“Nuclear power can bring health and prosperity to the 1.1 billion people in the world who currently do not have access to electricity,” stated World Nuclear Association Director General Agneta Rising at the International Atomic Energy Agency (IAEA) 60th Annual General Conference in Vienna, Austria.

In the fall of 2015, the global community met at the United Nations in New York and agreed to seventeen sustainable development goals (SDGs).  The goals; ambitious and universal, seek to end poverty; provide access to affordable, clean energy; make communities more resilient and combat climate change. Investments in SDGs have the ability to make noticeable improvements to the health, environment and economics for both developing and developed countries.

The commitment to realize the achievement of SDGs by 2030 requires nuclear.  Nuclear science and technology meet nine of the UN’s Sustainable Development Goals, making investments in these sectors critical components to a prosperous tomorrow.

In Spain, where nuclear power supplies about 20 per cent of the grid, a combination of factors including premiums placed on renewable energy has resulted in sky-high electrical bills as prices rose by almost 60 percent in the six years from 2006-2012. The result of the increase is that millions of people, especially those on fixed incomes, have been left in the dark.  Reliability and economics are key to improving the living conditions of people all over the world and the United Nation’s goals will hope to close the gap between energy security and the economics of electricity.

At the same time, energy choices must not further damage the environment with high carbon emissions.

The sector responsible for the greatest amount of emissions is electricity and heat production.  The fast and effective decarbonizing of this sector will require heavy investments in all low-carbon technologies. The Union of Concerned Scientists, amongst many others, has voiced that “limiting the worst effects of climate change may also require other low or no-carbon energy sources, including nuclear power.”

As a low emitter, nuclear power produces virtually no greenhouse gas emissions or air pollutants and avoids an estimated 2 billion tons of carbon dioxide yearly. At the same time, nuclear power has the ability to meet the increasing energy demands of an expanding population in a sustainable, clean way.

Moving towards a successful 2030 may be challenging but one thing is clear, in order to get there nuclear power must be part of the solution.

Fighting Food Insecurity

Nuclear technology steps up to meet a huge challenge.

The world needs more food and lots of it. According to the World Bank, in order to meet growing global demands we must produce 50% more food by 2050.

At the same time, expanding populations and climate change threaten our ability to meet these goals. A recent report by United States Department of Agriculture (USDA) stated that, “as temperatures rise, crops will increasingly experience temperatures above the optimum for their reproductive development, and animal production of meat or dairy products will be impacted by temperature extremes.”Branch of an apricot tree with ripe fruits

Enter the International Atomic Energy Agency (IAEA). In order to produce more food under challenging environmental conditions and with less available land, scientists from the IAEA are working with the Food and Agriculture Organization of the UN to find solutions to food insecurity.

One solution is the Nuclear Techniques in Agriculture program, a way to address food shortages through, “using radiation induced mutation, mutation detection and pre-breeding technologies.” Exposing plants to small doses of radiation can make them more resistant to disease and climate change.

One of the foods being targeted by this program is quinoa. This gluten free grain, common to the Andean people, is known as a complete protein, containing all nine essential amino acids. Because of its genetic diversity, quinoa is able to be grown under different environmental conditions, making it an appealing crop to grow; almost 100 countries currently harvest it.

Food irradiation can also help to kill potentially deadly bacteria and the use of isotopes can help to measure resource levels such as the health of soil and water storage within the land, providing farmers with important information on the health of their resources so that they can more effectively use their land to yield greater harvests.

As part of addressing food security issues, the International Atomic Energy Agency (IAEA) is using its sterile insect technique (SIT) to help Mauritius fight back against fruit flies. Fruit flies, native to Southeast Asia, attack a variety of much-needed produce including bananas, mangos, eggplant and squash. In a release by the IAEA in mid-June the Minister of Agro-Industry and Food Security for Mauritius addressed the magnitude of the problem.

“160 million Mauritian Rupees-over 4 million Euros-are lost annually as a result of the damage caused by fruit flies,” according to Mahen Kumar Seeruttun, Minister of Agro-Industry.

Being able to save crops and produce more bountiful harvests means the ability to address starvation and provide much needed nutrients. Today, it is estimated that 2 billion people live with food insecurity and that one in eight are starving, highlighting the importance of these nuclear initiatives. From hunger to hope, technology can help to fight back and feed those who are most in need.
