(RE)Solutions to Reduce Future Climate Vulnerability in Food Systems

Source: www.wholebodyreboot.com
It is clear that one of the main issues we face when ensuring global food security is climate change. Therefore, it seems obvious that our main solution here is reducing global greenhouse gas emissions, switching to renewable sources of energy, adapting more sustainable agricultural practices, et cetera. As mentioned in other previous posts, we would benefit to staving off red meats and switching to more plant-based diets, as well as highly reducing our waste of food, and even our consumption. However, it's all well and good to say these things coming from a western perspective, where everything is readily available... Yet, most of our food is often grown abroad. Especially staple goods, like rice and wheat. It may be easy for us to switch these parts of our society, but it's not that simple for others developing nations, who rely on selling off rainforests for agricultural land (like in Amazonian countries), vast fossil fuel industries (like China) and large industries that need to increase their GDP at the expense of exploiting their workers. Things aren't always as black and white as they seem... But as privileged people, we should be doing more.

As mentioned in a few previous posts, food security is characterised by three main pillars: access, availability and utilisation. Therefore, to reduce vulnerability to external factors, such as climate change, conflict, disease and the likes, we need to ensure that we achieve security in all of these individual sects.

Availability

Gregory et al. (2005) believe that boosting production is our solution to increasing availability of food. Although this is difficult to dispute, they interpret this as increasing intensification of agricultural production, cultivating new agricultural land, increasing widespread use of chemical inputs (fertilisers, pesticides, etc.) and furthering development of genetically modified crops (which will be discussed in further detail next time).  Contrarily, the FAO disagree by stating that we need to move forward with "climate-smart" methods of agriculture. To be fair, we cannot expect nations to switch to sustainable practice, if they have not been educated or encouraged to do so. Therefore, we must campaign to reduce government subsidies that push small farmers to engage in unsustainable practices, and educate the globe about how to integrate pest management and boost yields with minimal fertilisers. Additionally, we need to increase international funding for the adaptation and mitigation of climate change for developing nations, as presented in the COP21 agreement, to reduce future global food insecurity.

Access

Poverty and infrastructure are two key elements impacting global access to food, which both boil down to economies and available money. Gregory et al. (2005) comment that we need to improve food distribution, such as enhancing transport infrastructure and political agreements that circulate food faster in cases of emergency, as well as increase economic access to food by introducing policies that cut out middle men, lowering price of production, encouraging economic growth and providing political stability. The latter point (to increase economic access) contradicts the ideas put forward for improving availability, as industrial practices reduce agricultural employment, increase production costs, and reduce GDP per capita. Thus, to improve access, we must introduce more sustainable and local agricultural practices, that serve local communities. In respect to improving transportation, this can indeed certainly be said for developing countries, however possibly less so for developed nations, who should in turn be working hard to reduce their carbon footprints within the transport sector, and instead look to grow and import food more locally.

Utilisation

Defined as the "appropriate use based on knowledge of basic nutrition and care", utilisation refers to the education of its users and producers. Thus, to increase security in food utilisation, our main priority must be to educate farmers, producers and consumers in sustainable and secure practices, healthy and environmentally-friendly eating, and the reduction of food waste.


In short, it's incredibly difficult to gauge how to best increase future food security, and one that policy-makers have found challenging for decades. In a world where individuals focus on gaining personal profit at the expense of others, and environmental degradation is a "future matter", it's hard to see everything for what it truly is, instead of how it may appear... As westerners, our smart phones are often made out of conflict materials, our clothes made through slave labour, our electricity provided at the expense of suffocating smog, GHG emissions and pollution, our food processed beyond recognition, and our wars that serve agendas to be seen fighting the "war on terror". We have it so easy, yet it is never enough... So, to really reduce your impact, think about what you need, why you need it, and how best to obtain it ethically and environmentally...

Post-Christmas Food Waste Facts and Foibles

,
Food Waste - how it is recycled from RecycleNow on Vimeo.

Almost all of us waste food, whether we'd like to admit it or not. Although some items are destined for waste, like fruit peels, egg shells and meat bones, we throw away food that is perfectly edible, sometimes without realising. Here are some food waste facts, provided by Recycle Now and Love Food Hate Waste:

  1. Approximately 7 million tonnes of food waste is generated in the UK each year
  2. The average household wastes around £470 worth of food per year
  3. The average family wastes around £700 worth of food per year
  4. About half of the food wasted in the UK comes from our own homes
  5. Wasting edible food contributes to 4% of the UK water footprint
  6. The common food to be wasted is fresh food, such as, vegetables, fruit, bread, etc.
  7. In the UK, we chuck more food in the bin than the packaging around it
  8. If you throw food in the bin, the waste goes to landfills where it decomposes and releases vast stores of methane. This is equivalent to the emissions produced by 25% of cars in the UK, and thus is conducive to deadly climate change.
  9. HOWEVER, food waste reduced by 1 million tonnes from 2007 and 2012. And potentially more since. If we follow France's example of retailers donating their surplus, then we can seriously make a huge impact!

I thought this post to be particularly apt the day after Christmas, a day in which we engorge and spoil ourselves greatly, and consume lots of food (probably more than is necessary). This ultimately results in large quantities of waste. Although we can treat ourselves to this one day of indulgence every year, in a world where 793 million go hungry, it would the very least to ensure that we try to utilise all our leftovers. Here are a few recipes to consider before throwing away those tasty bites!

Global Food Insecurity

Welcome back to the Global Hot Potato! For the first few weeks of our blogging journey, we will be looking specifically at one side of the coin: how food production practices impact the environment. So make sure you strap in, as we will be exploring a combination of research, articles, reports, and environmental models to measure past/present impacts and predict future events. But, before we delve into the gritty details of the food production industry, we should first take a brief look at the current challenges we face today when it comes to feeding the planet.

To adequately address these challenges, we must first consider what it means to be without them, i.e. food security. In 2002, the UN’s Food and Agricultural Organisation defined food security to be “a situation that exists when all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life”.[1]  We know through the prevalence of poverty across the globe that this has not yet been achieved. But why? Are there too many of us? Is there not enough food? What’s going on here?

A growing population has a massive impact on global food insecurity. Although it is hard to predict the potential carrying capacity of the Earth, the World Food Programme states that there is enough food produced globally to feed the entire population, which was last measured to be nearing 7.4 billion people. Yet, despite this, an estimated 793 million people live undernourished and in food poverty. Although there has been a decline since 1990-92 (Fig.1), that's still a whopping 10% of the world population!!! But, if there isn’t a global shortage of food, then why are there so many people living in food poverty?

Fig. 1: a comparison between the proportion and location of people in food poverty in 1990-1992 and 2014-2016

The World Health Organisation considers there to be three cornerstones affecting food security: access, availability and use.
  • Limited access to food can be largely attributed to increased poverty, where individuals do not possess the resources necessary to obtain sufficient nourishment. This was a particular topic on concern in 2008, when food prices reached an all-time high, seeing many people with decreased access to healthy, nutritious food across all parts of the planet. However, in today's world, approximately 98% of the malnourished population are living in less economically developed regions (Fig.1), showing us that the economy plays a huge role in global food security. 

  • One of the biggest factors influencing the availability of food is climate change. Certain regions are experiencing increased drought, flooding and unprecedented natural disasters, which is having a major impact on our ability to grow certain food in affected areas and decreasing potential yield. Not to mention that food production itself is contributing  largely to climate change, creating a unsustainable cycle of food insecurity (but I will get into that more later).

  • The way food is used can refer to the knowledge and care for our food, (e.g. understanding nutrition and food hygiene). It can also refer to what we actually DO with our food. Did you know that one third of all food produced is thrown away? ONE THIRD!?!?! What?!?! We destroy landscapes, produce tonnes of greenhouse emissions and waste precious water to produce our food just to throw ONE THIRD of it all away?!!! I can't help but find that truly horrifying…


It seems clear that our current methods of food production are unsustainable. With an increasing population projected to reach 9.6 billion by 2050, how do we intend to cope with this increasing demand sustainably, without irreparably damaging the Earth, and without leaving millions in food poverty? Before we can even begin to contemplate this huge question, we will need to take a look at what current food production practices are being utilised across the global and evaluate the environmental and social impacts these practices have. We will then consider the role modelling has in measuring these impacts and predicting the future. In my next post, I will starting by focusing on the industrial livestock production: past, present and future.
