In speaking of food waste we often hear about the environmental consequences: waste of land use, energy, water, our natural surroundings, and so on. However, the real cost of food waste is not only paid for by nature, but also by people. This blog dives into the social impact of a malfunctioning food system, in which over 30% of the worldwide production of food is wasted (FAO, 2018) while at the same time one in nine people does not have access to sufficient nutritious food. What is the state of hunger worldwide, versus the state of food waste? Who are the ones most affected? What are the main consequences that they carry? In other words: how can the food system be balanced out?
By becoming more aware of the social consequences of a malfunctioning food system, including food waste, we can strengthen the view on our role within a global food network. It will show that the smallest action that aid the reduction of personal food waste does make a difference in changing the planet’s and people’s health. Accordingly, we look for ways to achieve social as well as environmental justice through the food-related choices we make daily.
A closer look at the issue
Our food system has developed into a system stimulating continuous growth, in many cases at the expense of life on the planet and livelihoods of people. Some people are more affected by this than others, but ultimately it harms everyone. The current production of food is enough to feed the world population twice (WFP, 2018). At the same time, roughly one in nine people worldwide suffer from hunger (FAO, 2018). It is clear that a profound change in the food system is needed to nourish the 800 million people that suffer from undernourishment in a way that ensures the health of the planet.
The global population is expected to grow with 2.3 billion people by 2050, counting almost ten billion people in total. The food production should increase with 56% to feed all those people. Or: we can reduce our food waste and not have to increase in food production at all.
On the macro-level, plans are made to reach targets to reduce food waste and nudge consumers’ behaviour in the right direction such as streamlining expiration labels and eliminating the use of trays in cafeterias (see box) (Ranghanatan et al, 2018). A big share of the waste, however, still happens on the micro-level: within households. Figure 1 shows where food is wasted on the consumer level the most.
Figures are consumer waste per capita based on data from the 2007 FAO report ‘Global Food Losses and Food waste’. Globally, consumer food waste amounts to roughly 350 Mt which equates about 50 kgs per person or 10% of total food supply (Gustavsson et al (FAO), 2011
In the figure we see that the so-called high-income regions, defined by the World Bank, and Food and Agriculture Organization (FAO), have the highest share of wasted food at the consumption level. The USA, Canada, Australia and New Zealand produce a striking 110 kgs of food waste per person each year.

So: how does that relate to undernourishment? Whilst the number of undernourished people was steadily falling from 2005 – 2014, it has started to increase again in 2014 and has since risen again to 821 million people (Hutt & Gray, 2015). The following chart shows where undernourishment is prevailing, globally.
The chart shows that the largest part of undernourished people live in Sub Saharan Africa and South Asia. So the regions where most food is wasted on the consumption level are the ones where hunger is least prevalent. This raises a moral question: how we can justify wasting the food that people in low income countries apparently are in such great need of?
Less food waste, more food security…?
To a large extent, the social impact of food waste relates to environmental consequences. The next figure gives an overview of those environmental costs.
A growing global demand will put extra pressure on the agricultural sector. However, the need to produce more food can be offset dramatically by reducing the amount of food that is wasted. This also seems like an ethical thing to do, as societies carry most of the costs of the environmental impacts of food waste. First of all, simply said, human efforts to produce food that does not get a use, is wasted effort. Secondly, the pressure on countries to produce food is increasing as population grows. At the same time regions such as Sub Saharan Africa and the MENA-region also experience increased pressure on their agricultural productivity due to the effects of climate change. Soil is degrading, water resources are getting more scarce and more extreme weather conditions occur. If no serious system change takes place, the risk of a global food crisis is inevitable.
Rural women’s role in food security
The ones who are most affected by the increased pressure on the food system are rural women in low income countries. Women feed least and last in the countries that are faced with hunger, conflict and famine. Therefore, rural women are part of the so-called “left-behind category” (Nyirongo, 2018). Famine and hunger are not related to the fact that there is not enough food for people; it relates back to the access that people have to the food that is available, which is a political issue. Regarding food access, women are last in line. There are three reasons why:
Deep-rooted gender norms. In many countries, the case is that women only eat after the men and kids have had food. Especially when crisis hits, women are the first to sacrifice their food to make sure the family has enough. Women do 2.6 times more unpaid care and domestic work than men do and earn 23% less for paid work (ILO, 2016).
Man-made conflict. Man-made conflict is the number one driver of food insecurity and women are hit hardest by that. As men fight in conflicts, women become the head of the household, yet having little to offer to their families due to a lack of resources. Additionally, women are more subject to abuse, violence and abduction from their homes in times of conflict.
Lack of women’s rights. In many countries, women have less power and less rights compared to men. Even though women make up for more than half the world’s agricultural workers, they do not own any of the financial means, land or tools to farm (WFP, 2018).
Challenges for the role of rural women for development, food production and poverty eradication are further complicated by a changing climate, food price inflation and economic crisis. Women empowerment is essential, not only for the well-being of communities, families and individuals, but also for overall economic productivity. Women are key agents in development as their productivity level is higher than men’s. A study of the Food and Agricultural Organization (FAO) estimated that if women had equal access to resources as men (tools, land, credit etc) agricultural output would rise up to four percent. This might not seem like a lot, but globally, as a high share of low-income countries are active in the primary (agricultural) sector, this definitely adds up. Additionally, if women are given the opportunity to control household income they are more likely to spend it on food, health, clothing and education than men are.
Improvements in food security can be made by, for instance, improving rural women’s access to agricultural resources and credits and enhancing decision making and ownership within households, communities and at government-level. Gender equality is essential in achieving food and nutrition security and contribute to social and economic growth, both now and in the future.
Globally, a clear pattern is visible: in high-income countries most food is wasted consumption stage of the food supply chain. Low-income countries hardly waste food at that level. These countries that largely rely on their primary sector, of which agriculture holds the largest share, suffer the most from the consequences of food waste because it puts pressure on their capacities. At the same time, they encounter the greatest problems in the agricultural sector such as heat and drought, water scarcity and more extreme weather conditions due to climate change.
The prevailing food crisis is a direct consequence of food loss and food waste practices, of which rural women in particular are affected the most. To solve these issues in the food chain it is important to empower rural women, as not only does it reduce inequality, it also increases agricultural productivity, and investment in the community that women take part in.
But: we shouldn’t forget the responsibility that the consumer has on the other end of the food value chain. System changes can come from here, too. The question isn’t only: how can we increase agricultural productivity to meet the nutritional needs of ten billion people in 2050? But: How can we make better use here and now, of the food that already exists? This is where we should strive for making healthier choices in consumption, both for the people as the planet. Cutting down on meat consumption would be a major step ahead, as this relieves a lot of pressure off the planet’s resources and lowers greenhouse gas emissions. Combating food waste is another major one. With that we can influence the lives of those most affected by the malfunctioning food system on the other end. Now, why should we care? Because, as Martin Luther King said: “Injustice anywhere is a threat to justice everywhere. We are caught in an inescapable network of mutuality, tied in a single garment of destiny. Whatever affects one directly, affects all indirectly.”
