Future of Food Lies with Our Youth


“But if we are seeking to better acquaint people with food so the world can meet the challenge of feeding 9 billion by 2050, we must get some of those 9 billion people interested in agriculture now.” 
  -Mary Beth Albright
Everyone says that our future lies with our children and we have to educate our children in order to secure our future. In this article, I found interesting this concept of prepping our future for the challenges to come with feeding 9 billion people. If the idea of farming as an occupation among the youth is in decline, then the main focus of our efforts should be on encouraging and educating the youth about agriculture to increase interest. I find this important because of the fact that having food but no farmers to tend to it and no way to monitor the farmlands will decrease our ability to grow crops and ultimately decrease food security.
This article expands on this concept by sharing a story about when the author cooked a four-course meal with 6 children on a farm for about 13 people. In the article the author gives an explanation of why teaching of children how to harvest and cook was so important. It was said that although the kids did not eat all of the food, the harvesting and cooking was enough to plant the experience in their heads and help it develop. Can we say that we have been actively trying to educate the youth about agriculture? Some may say yes, but the fact is if we do not focus enough attention on the youth now, securing food for the future will be futile. I completely recommend this article for people interested in food security because it represents a way for society to begin working on our future to sustain.

Food Security on a Warming Planet

As this century progresses, the issues of climate change and food security intensify and become more intertwined. This was a major talking point at the United Nations Climate Summit 2014: Catalyzing Action. As the effects of climate change become more and more severe, the ability to grow, harvest, and produce sufficient food supplies becomes more unstable. The U.S. Global Change Research Program reported a huge disruption to agriculture directly as a result of climate change. With climate change showing no signs of slowing down, these problems are projected to continue and worsen in the future. The effects of climate change will have huge impacts on food security locally and internationally.

The American Midwest is one of the world's largest growers of food.  Recently, it has been experiencing increasingly severe droughts, which have negative effects on the yields. Because of the global nature of humanity's food system, the poor harvests in areas like the Midwest can directly harm those in less affluent countries who are already unable to meet their domestic nutritional needs. In another part of the world, similar droughts have wreaked havoc. In parts of sub-Saharan Africa, food productivity relies heavily on large quantities of rainwater, thus further destabilizing the food situation. Food shortages historically have contributed to civil unrest as well.

Members of the UN have responded by suggesting the implementation of "climate-smart agriculture" to produce more robust yields in the face of a changing climate.  "Sustainability" seems to have been the buzz word for years, and when it comes to food security, it could not be more important.

In addition to the UN's emphasis on improving agricultural techniques, it might also be wise for governments to contribute more to research for stopping, or even better, reversing the effects of climate change. Primarily, this would involve searching for cleaner, sustainable sources of energy for transportation fuel and electricity.  If the world is going to continue to advance technologically and allow individuals around the world to enjoy its benefits, significant scientific effort must be placed in ensuring the sustainability of this progress.

Ebola and food security


            In midst of the panic over the Ebola outbreak and the first US Ebola patient, it is important to recognize that the effect of Ebola reaches beyond the terrifying symptoms and speed with which it spreads.  Recently, the UN Food and Agriculture Organization conducted an assessment in northern Liberia that concluded that the Ebola outbreak has had a significant effect on food security in Africa as well.
            Production of food slowed 10-25% in certain areas as people became too afraid to work in the fields.  The majority of Ebola victims are also of working age, which means that households affected by the disease also lost people who could have worked in the fields.  This also means that household income decreased as well.
            This decrease of production and income coupled with panicked purchasing of food resulted in food shortages and price fluctuations.  Any food that was left became harder to trade – in order to prevent the spread of Ebola, local authorities closed down markets where people would normally buy and sell food.  The effect of these high food prices percolated throughout the economy as other commodities like fuel also became more expensive.  As a result, savings that local residents had accrued were drained, and people were no longer able to repay the loans they had taken out to start farming-related businesses.
            In the upcoming months, it is estimated that 1.3 million people in Guinea, Liberia, and Sierra Leone will need help feeding themselves.  Furthermore, these countries had generally already imported more food than they exported, and border closures and quarantines will prevent open trade of food.

            I think this case illustrates several things.  First, it shows how intimately food security is tied to so many different facets of society due to its nature as one of the basic human necessities.  Second, it shows how important building resilience is for food security in case of unpredictable shocks such as the Ebola outbreak.  Third, it shows that preserving stability is necessary from the very start of a crisis before other issues emerge as a result.

Food and Fukushima: Radiation Levels and Their Effect.

A recent study published in  BMC Evolutionary Biology by researchers Chiyo Nohara, Wataru Taira, Atsuki Hiyama, Akira Tanahara, Toshihiro Takatsuji, and Joji M Otaki has some serious implications on food security.

While the study looked specifically at one species of butterfly, Zizeeria maha, and the radiation levels within their body, it was the reason why these butterflies were so affected that is the cause of concern. These butterflies eat large amounts of leaves from the surrounding area around the Fukushima Power Plant location.

The high spikes in radiation ingested by these butterflies suggests that wildlife in the area has been seriously affected by radiation, and it permeates all levels of the food chain.

While their study shows that these changes drop immediately next generation if they are fed normal non-radiated food, the ability for the radiation to disappear like that in a natural setting in unlikely.

The FDA in March released a statement saying that US food safety has been unaffected by these radiation levels, but what about in other countries closer to the disaster?

Shows abnormalities in butterflies in the study
In Japan, a study was performed on the people who lived near Fukushima, and found that people who ingested "homegrown produce without radiation inspection, and often collected mushrooms in the wild or cultivated them on bed-logs in their homes.” were more likely to have high levels of radioactive cesium levels within them. People who regularly ate wild boar meat and river fish also had the high levels of cesium in them.

Many studies have been performed on the food safety in regards to radiation poisoning, and none so far have found any harmful levels of cesium. However, this study shows that it exists and is something that needs to be address in the near future.The researchers point out these needs, and hope that this will push for further testing of food grown locally in the area.

The Biodiversity Risks of GMOs

Ecuador, surrounded by larger countries, has very few things that the world requires as exports, but the banana industry supports an incredible amount of the population directly and indirectly. Ecuador is the largest exporter of bananas in the world, coming before the Philippines, Costa Rica, Guatemala, and Colombia, and most of the produce goes straight to the U.S. The increase in banana exports has been a great aid to the Ecuadorian economy after the problems caused by the recession and dollarization in the 1990s and 2000s.

Unfortunately, this booming industry is now facing a fungus that could destroy the livelihoods of many small Ecuadorian farmers. The serious disease, named TR4, risks a variety of banana that account for "95% of global export market for the fruit" (livetradingnews.com). This specific variety was chosen as most popular because of its resistance to the Panama Disease. The new disease is quickly spreading through all banana farms throughout Asia, the Middle East, and Africa and has yet to reach Central or South America. Ecuador has yet to declare what preventative measures they are taking, which poses the question of what will the government and farmers do if or when the disease reaches the country?Although the banana industry has faced disease emergency's in the past, none have had as great of consequences as this one might.


Currently, there is no known cure or treatment for the fungus once it has infected a field. The only option is to isolate the infected trees. The fungus remains in and on the soil for over 10 years, meaning that the area would be unusable for banana production. The specific variety of banana, called Cavendish bananas, was originally genetically modified to prevent the Panama Disease (Fusarium) already mentioned. Now, a majority of the bananas produced are Cavendish bananas that also happen to be the most affected by TR4. GMOs can be used to improve food safety and security all over the world, but they also limit the ecological biodiversity within the crop varieties, leading to the current banana crisis.

How can we prevent such catastrophes with genetically modified crops from happening in the future while still finding solutions to food security?

Rooftop Gardening


When one imagines solutions to our food crisis, the idea of rooftop farming often comes to the conversation. Initially, this appears to be a seamless solution to many of the problems we face, including food deserts and lack of space in urban areas. However, although there are various rooftop gardens in place in many cities around the world already, little actual scientific research and data has been performed and collected on the feasibility of this idea. This lack of data has in turn potentially been delaying the further implementation of more roof gardens.
This is a problem Whittinghill et al set out to fix when they performed a study from 2009 to 2011 on the evaluation of vegetable production on extensive green roofs. This study was performed on the roof of the Michigan State University Plant and Soil Sciences Building over the course of three growing seasons. The researchers chose a variety of herbs and vegetables that are typically suited to the standards and restrictions of rooftop growing, and planted these in roof beds, elevated roof beds, and in a location on the ground. The results of the study indicated that the growing system had little to no effect on the total yield, although the grade and marketability of the produce suffered greater on the roof than in the ground.
Throughout the study, it was apparent to the researchers that weather played the largest role as to whether or not the plants would produce, not the medium or location in which the growing occurred. These were very hopeful signs that indicate rooftop growing as a potential supplement to ground agriculture. However, this type of growing does not come without its fair share of headaches, and its issues of feasibility may discourage some from attempting this potentially revolutionary technique. Rooftop gardens have a different array of pest problems as opposed to the ones we are acquainted with on the ground. Likewise, there is also a lack of pollinators at the heights of certain buildings. Plants on roofs are also exposed to more heat, which could be greatly beneficial in areas like Michigan, but detrimental in the south. The initial costs, along with the structural integrity of the roofs, are the main issues one faces when installing a rooftop garden. In order to have reliable proof that this type of food production is useful, there is a great need for additional scientific studies to be performed in order to assure growers and lay citizens that this technique is worth the cost and time.
