Abstract(s)
The unadjusted intake of food constitutes a real challenge for the several sustainability
dimensions. In this perspective, the main objectives of this research are to characterise the current
contexts of food security, its relationship with sustainability, and identify proposals and actions
that may support the design of more adjusted policies in the future. In addition, it is intended
to assess if the food security pillars properly address the sustainability goals and if the evolution
of undernutrition is accompanied by sustainable frameworks. In this way, statistical information
from the FAOSTAT database was considered for the several dimensions of food security over the
period 2000–2020. These data were analysed through factor-cluster approaches and panel data
methodologies, namely those related to quantile regressions. As main insights, we may refer that
undernutrition is more impacted by the availability of food and nutrients and political stability
than by the level of GDP—Gross Domestic Product (except for the extreme cases). This means that
the level of development is not the primary explanation for the problems of nutrition. The main
focus of the national and international policies must be to improve the agrifood supply chains and
to support political stability, in order to mitigate undernutrition worldwide and ensure a global
access to sustainable and healthy diets. In addition, it is suggested to rethink the four pillars of food
security (availability, access, utilisation and stability), in order to encompass other dimensions, such
as climate change.
