Abstract
Organic
production and consumption provide a delineated food system that can be
explored for its potential contribution to sustainable diets. While
organic agriculture improves the sustainability performance on the
production side, critical reflections are made on how organic
consumption patterns, understood as the practice of people consuming
significant amounts of organic produce, may also be taken as an example
for sustainable food consumption. The consumption patterns of regular
organic consumers seem to be close to the sustainable diet concept of
FAO. Certain organic-related measures might therefore be useful in the
sustainability assessment of diets, e.g., organic production and organic
consumption. Since diets play a central role in shaping food systems
and food systems shape diets, the role of organic consumption emerges as
an essential topic to be addressed. This role may be based on four
important organic achievements: organic agriculture and food production
has a definition, well-established principles, public standards, and
useful metrics. By 2015, data for organic production and consumption are
recorded annually from more than 160 countries, and regulations are in
force in more than 80 countries or regions. The organic food system puts
the land (agri-cultura) back into the diet; it is the land from which
the diet in toto is shaped. Therefore, the organic food system provides essential components of a sustainable diet.
Keywords: food system, consumption, diet, nutrition, sustainable nutrition, sustainability, health
Introduction
The
interest in sustainable diets is steadily increasing; for active
stakeholders from all agro-food sectors the broader and complex context
of the sustainability of food systems is highly relevant for policy and
practice (1).
Defining a theoretical methodological framework for the assessment of
the sustainability of diets presents many challenges. The definition of
sustainable diets reached in 2010 at the conference organized by FAO and
Biodiversity (2)
and the associated four dimensions (health and nutrition, environment,
economic, socio-cultural) provide a starting point for a list of
indicators serving sustainability assessment (3).
The
traditional Mediterranean diet, scientifically well-characterized as a
healthy dietary pattern, appreciated for its lower environmental impact
and acknowledged as a cultural heritage, is used as a model to assess
sustainability of diets and food consumption patterns in the
Mediterranean area, using indicators proposed by a Working Group (4).
Members
of the International Food Quality and Health Association (FQH) and
colleagues explored the organic food system as a case study and its
potential support for sustainable diets. FQH experts contributed to a
scientific debate on how to address the question of sustainable diets
within organic production and consumption concepts and achievements, and
what role the organic sector can play to change the global food systems
toward a higher degree of sustainability. The aim of the current paper
is to resume the output from a seminar arranged in Rome in September
2014 to address these topics, and to explain why the organic food system
deserves the role as a good example for developing a global sustainable
diet.
From the Organic Roots Until Today
The
context of our diets within food and agriculture systems and the global
challenges compel us to address certain issues. Industrial food systems
have proven successful in making more food available at a low price.
Yet, notwithstanding that some progress has been recently observed, the
number of malnourished and hungry people in the world remains
unacceptably high (5, 6).
At the same time and worldwide, overweight and obesity are increasing
among adults and, even more alarmingly, among children (7).
The huge amount of food produced is not equitably distributed and,
furthermore, roughly one-third of the edible parts of food produced for
human consumption are lost or wasted globally (8).
In medium- and high-income countries, food is to a great extent wasted,
i.e., it is thrown away even if it is still suitable for human
consumption. The industrial food systems have developed a strong
dependence on fossil energy and caused an undeniable negative effect on
the environment (9).
Against the background of a looming 9.6 billion people on earth in
2050, many scientists argue for a further intensification of
agricultural systems. The organic food system might offer an alternative
approach toward sustainable development of the global food system. Even
in resource-poor settings, organic management of small farms has been
shown to significantly increase yields, improve soil fertility, and
water-holding capacity (10–12), enabling a better use of farms’ own resources and reducing dependence on bought inputs (13).
The
historical development of the organic food system is relatively young,
about 90 years old in Europe, but developing very quickly. The history
of the organic movement has a clear and logical sequence: first came the
philosophy and teachings, which were based on observation of nature and
respect for natural laws. In turn, the organic pioneers transformed
these principles into practical farming methods. After development in
central Europe, organic agriculture was implemented in nearly all
regions throughout the world. Today the organic system is a worldwide
food system (14).
Such growth is positive; however, it creates a challenge – how to keep
high effectiveness together with high quality of produce and basic
standards of the organic production having their roots in the pioneer
ideas (15).
The
organic food system can be described from the organic vision all the
way through to the metrics. This includes a food system that raises
incomes and increases food security and food safety at both ends;
furthermore, as one in which the environment is preserved while farmers
and workers have fair access to the means of food production. Today, the
system is described in the Codex Alimentarius (16) while the vision is laid down in international standards [e.g., Ref. (17)]. Organic agriculture is defined in a way that reflects the underlying principles (see Box 1). With respect to food, the term organic
is defined through the principles of organic farming and food
production. Organic food quality is defined through process- and
product-related aspects (18). There are legal definitions containing regulations in place in Europe (19, 20), Japan (21), and the United States of America (22)
both at the national and private standards levels, including a thorough
certification process. Indeed, 86 countries around the globe have
organic legislation. Evaluation is performed through criteria,
indicators, and parameters that can be organic specific. There is a
clear connection between the regulation at farm and industry level and
the impact on environment and food. In Europe, the organic logo is well
recognized by the European consumer and is associated with a sustainable
and healthy food system (23–25).
Box 1
“Organic
agriculture is a production system that sustains the health of soils,
ecosystems, and people. It relies on ecological processes, biodiversity
and cycles adapted to local conditions, rather than the use of inputs
with adverse effects. Organic agriculture combines tradition, innovation
and science to benefit the shared environment and promote fair
relationships and a good quality of life for all involved.” [Ref. (17): p. 31].
On the Dimensions of Sustainability
The
framework for Sustainability Assessment of Food and Agriculture (SAFA)
systems is used for farms and companies to analyze the sustainability of
these organic food chain links (26).
Divided into four dimensions (environment, economy, social, and
governance), it covers 21 themes and 58 subthemes with defined
objectives (27).
Preliminary research shows that organic production impacts the entire
food system and that organic agriculture can contribute to the main
strategies for sustainable food systems: efficiency, consistency, and
sufficiency. For a better understanding of this contribution and
exploring future scenarios, quantitative models that link food demand,
agricultural production patterns, and sustainability impacts are needed (28).
Environmental
impacts can be further probed, using the life cycle perspective. As
previous studies have shown, in general the agricultural practice has
the greatest contribution to environmental impacts of food products (29, 30)
but most of the studies focus on the impacts within the farm gate.
Hence, environmental effects of transport, processing, and distribution
are often excluded. Furthermore, the effect of changing consumption
patterns on the effects of the production, such as decreased or
increased consumption of meat, is usually not included. The
environmental impacts of a diet could be formed as the sum of impacts of
each component of the diet, using the life cycle assessment (LCA)
approach, a tool to assess the potential environmental impacts, and the
use of resources through a product’s life cycle (31).
However, there is a lack of studies that include different processing
technologies, distribution, and consumption possibilities. These next
stages can also have a significant impact, e.g., caused by energy
consumption in processing, transport, food losses, and consumer
behavior. To enable fair comparison of the environmental impacts of
different diets, the selection of functional unit, i.e., the unit in
which all impacts are reported, is essential.
Looking
to the dimensions of nutrition, economy, society, and culture, key
messages include the observation that the consumption of organic food
within a diet exhibits certain recurring characteristics, such as a
shorter chain in terms of the degrees of separation to the primary
producer (32).
It is hypothesized that a diet including significant amounts of organic
produce is economically fair and affordable, if the diet is sustainable
according to the definition (see Box 2
insert below). An alternative indicator to assess the sustainability of
diets for the dimension of society and culture might be the degree of
training in household skills in schools. This criterion offers potential
use for policy formulation. Indeed, education-linked measures, such as
food, health, or nutrition literacy, and especially ecoliteracy (33, 34), might offer some further value.
Box 2
“Sustainable
diets are those diets with low environmental impacts, which contribute
to food and nutrition security and to healthy life for present and
future generations. Sustainable diets are protective and respectful of
biodiversity and ecosystems, culturally acceptable, accessible,
economically fair, and affordable; nutritionally adequate, safe, and
healthy; while optimizing natural and human resources” (2).
Furthermore, there is growing evidence from profiling organic consumers, e.g., in Germany (35) or France (36),
of significantly different dietary choices made by such groups,
specifically more healthful choices. Additionally, such data show better
nutritional anthropometry measures and physical activity prevalence for
organic consumers (37).
A detailed study on the profiles of organic food consumers comprising 54,311 adult participants (36) was presented from the French Nutrinet-Santé cohort (38).
The results were in astonishing agreement with those from the German
study on organic consumers using data from the National Nutrition Survey
II (39, 40). Regular consumers of organic products in both the French and the German cohorts exhibited:
- more plant food based;
- a diet fitting food based and nutritional recommendations;
- markedly less overweight and obesity;
- a higher level of physical activity;
- a non-smoking routine.
Regular consumers of organic products have
healthier lifestyle profiles overall and thus a better compliance with
the sustainable diet concept [more plant foods, better nutrition, better
safety, better lifestyle, and health (adiposity), to minimize
energy/water uses and environmental impacts]. Thus, regular consumers of
organic products exhibit an overall plant-based diet and a healthier
profile better fitting the sustainable diet definition (see Box 2 insert above).
The
next steps of the on-going BioNutrinet project will be to precisely
quantify organic foods consumption (total and foods/food groups), to
evaluate the impacts of five different levels of organic consumption on
dietary patterns and nutrient intakes, to determine some impacts of
regular organic consumption (versus none), such as energy or water use
and environmental pressure using allocated indicators, and to determine
pesticide exposure of consumers using pesticide residue analyses in
urine/plasma samples. The ultimate goal of this prospective survey will
be to assess the impact of organic food consumption on health and
well-being parameters.
Applying
ecological principles in the pursuit of a sustainable development in
agriculture is something that the organic approach shares with the
agroecology approach. Using the agroecology perspective of the organic
food system shows that, like sustainability, this term also has
different meanings to different people, ranging from a purely academic
ecology focus to a social movement approach (41–44).
The relationship between organic and agro-ecological principles is
considered by identifying areas of common ground and of differences (45).
The question of how the agro-ecological underpinning of organic farming
can be better reflected in organic regulations in future needs to be
addressed. The value of certification lies is helping to translate the
organic principles into practice through definition of relevant
practices and technologies. The concept of certification should be a
foundation to support innovation, not a ceiling to constrain it. While
it enables markets to reward producers for adopting specific practices,
ensuring financial viability of systems, at the same time protecting
consumers, it can lead to bureaucracy and institutionalization,
disregarding delivery of the broader goals.
Two Case Studies Provide Insight into Practice in the Organic Food System
The
Mediterranean diet is characterized by enormous food diversity where
durum wheat is one of the bases, in the form of bread, pasta, couscous,
and bulgur. Throughout the Mediterranean different types of bread are
made from durum wheat, including traditional flatbreads. A project
studying the performance of organically grown old varieties of durum
wheat and traditional bread-making provides a case study of linking the
organic food system to the Mediterranean diet (46).
Organic consumers tend to choose organic breads that are locally
produced and handmade, and are processed with natural ingredients. Due
to that, traditional sourdough fermentation becomes a very interesting
biotechnology for bread making. Even though it produces a smaller loaf
size, it is still very appealing to consumers because of its unique
characteristics. Recently, there was a valorization of old, local
varieties of durum wheat particularly suitable for organic farming. It
seems possible to bring traditions and cultural history successfully
into modernity. The organic farming practices are undoubtedly a
determinant that affects the flour microbiota and, consequently, the
dynamic of the sourdough microbial community. The organic cultivation of
durum wheat affects flour quality and sourdough fermentation and could
be considered a suitable alternative for making sourdough breads with
distinctive attributes.
Increasing the
consumption of organic food, e.g., by supporting public procurement of
organic produce, is a measure that has been extensively utilized, e.g.,
in Denmark, the country in the world with the largest organic
consumption per capita (47).
Institutions are often used for a conversion to organic food serving,
but schools constitute a sector with a high potential, not least because
of the possibility a successful organic food serving implies to
influence the habits and preferences of young consumers. The
transnational research project iPOPY – innovative Public Organic food
Procurement for Youth (2007–2010), one of the eight pilot projects of
the CORE-Organic European research area network, was a market research
study on how to increase the consumption of organic food in Europe by
implementing organic food in school meals. Studies in Denmark, Finland,
Italy, Norway, and Germany showed highly variable conditions for school
meals, ranging from complete, free meals (Finland) to packed, private
lunches (Norway). To maximize organic consumption in schools, complete
meals should be served, paid for by the public, with strong public
involvement in general, with strong support for organic school food and
an adapted supply chain (48).
In Finland, the organic proportion was low, but the well-established
system has a high potential for significant organic consumption (49). In Italy, significant proportions of organic food were served, supported by public regulations, but hardly communicated (50).
Multiple embedding is required to establish a stable, high consumption
of organic food in schools. The CORE-Organic I project iPOPY showed that
organic food and farming are well suited to discuss and experience
sustainability in practice (51).
Analysis showed that an organic school policy promotes healthy eating:
schools with a healthy food policy also support organic food.
Conclusion and Outlook
The
underlying aim of the organic movement was and is still to create and
develop further an alternative food system with focus on primary
production (agriculture). To achieve this goal, it is increasingly
acknowledged that food processing, distribution, and consumption,
including sustainable diets, need to be included in the organic
approach. This approach aims at developing a sustainable dietary pattern
from field (agriculture) to fork (nutrition). As shown in this paper,
what may be called an organic food system offers an instructive example
of combining sustainable food production and consumption patterns within
one system. However, actually defining an organic food system needs
further research and development. Since sustainability issues have been
internationally discussed [Rio Earth Summit, Rio 1992; Rio + 5, New York
1997; Rio + 10, Johannesburg 2002; Rio + 20, Rio 2012 etc.], organic
agriculture has been placed as an alternative way of production and
discussed as a global best practice example. Therefore, during the last
decade, many studies and reviews were performed investigating how
organic agriculture and food production as well as parts of the value
chains contribute to sustainable food production. In parallel, the
market for organic food has grown exponentially worldwide. As a
consequence, studies on consumer behavior as well as consumption
patterns were also carried out. However, until now organic production
and consumption have never been brought together in a way describing the
complete organic food system. Furthermore, the link to sustainable
diets is implicated but, as the seminar in Rome concluded, needs further
investigation. While organic agriculture can be taken as an example for
sustainable food production, critical reflections were made on how
organic consumption patterns may also be taken as example for
sustainable food consumption. One of the inputs organic may offer here
are parameters where organic-related measures might be useful in the
sustainability assessment of diets and the notion of characterizing
organic value chains from a sustainability perspective on the basis of
the dimensions discussed (health and nutrition, environment, economic,
socio-cultural). Two potential indicators considered more closely were
for organic production (land use under organic cultivation in
percentage) and for organic consumption (organic consumption per
capita). Drawing on the definition of sustainable diets above, the
change of consumption patterns seems to be a crucial issue in the
transformation to sustainable food systems. The consumption patterns of
regular organic consumers seem to be close to the sustainable diet
concept of FAO. Since diets play a central role in shaping food systems
and food systems shape diets, the role of organic food consumption in
sustainable diets emerges as an essential topic to be addressed. An
argument for using the organic sector as an example to learn from while
designing a sustainable diet is the viability of delineating the organic
food system as a living laboratory. This laboratory has a clear and
generally accepted definition, four basic principles, internationally
acknowledged standards and it has useful and well-established metrics.
The organic food system has been in practice for the last 100 years and
covers environmental aspects, animal welfare standards, and food quality
as well as health issues. So, today it also has the data from more than
160 countries, and regulations are in force in more than 80 countries
or regions. The organic food system puts the land (agri-cultura) back
into the diet; indeed, it is the land from which the diet in toto
is shaped. Therefore, the organic food system provides the essential
requirements of a sustainable diet. An international multidisciplinary
project is being prepared to develop the concept of an organic diet more
in depth and evaluate how it plays a key role in the organic food
system as an important component of sustainable food systems.
