There Can Be No Sustainable Development Without Profound Changes In Food Systems


“There can be no sustainable development without profound changes in food systems”. This call for change was issued by an international group of experts dubbed the “Milano Group”, whose members have written an article published in the journal Agronomy for Sustainable Development.

Agriculture, the world’s biggest employer

Food systems are not just vital for achieving SDG2 (“Zero hunger”); they concern the entire 2030 Agenda for Sustainable Development. Since agriculture is the world’s main source of employment, investing in it is considered twice as effective at alleviating poverty than investing in any other sector.

Farming practices are closely linked to ecosystem health, natural resource diversity and renewal, and climate change. Lastly, food insecurity and rural poverty are often the root cause of political instability, conflict and migration.

“We need to totally transform food systems”

While the overriding priority for agriculture was for a long time to increase production, this century has brought very different issues. For Patrick Caron, the lead author of the article, a researcher with CIRAD and with CIRAD and Chair of the United Nations High-Level Panel of Experts on Food Security and Nutrition, “We need to implement a comprehensive transformation in food systems, centring on different paradigms and models from those of the 20th century”.

This call for profound change was prompted by the Milano Group’s discussions, which gave rise to a proposed four-pillar strategy.

Drastic changes in consumption patterns, with a shift towards healthy eating:

  • Ensuring that agricultural production and food supply chains play a greater role in sustainable development
  • Mitigating climate change by means of new farming practices
  • A package of operations aimed at rejuvenating rural territories.
  • Renewing governance of food systems

These changes will not happen on their own. The transformation will hinge on renewing food system governance, giving priority to human development and food and nutritional security, rational resource management, ecosystem health, and fairer development and consumption models. This means adopting new ways of designing, planning and managing programmes to support production, consumption, innovation and rural development.

Science has a major role to play

Science has a major role to play in generating vital knowledge, particularly in the technical field, and also in pinpointing the dynamics of transitions, identifying critical and emerging topics, characterizing interactions and compromised, clearing up disagreements between players, exploring possible future scenarios, and enlightening the decisions to be made regarding the solutions to be adapted to the various contexts.

Although changes are generally proposed and made on a local or national level, along very specific lines, the global scope and ambition of this transformation require a governance framework and processes on a global scale, particularly as regards processes for arbitration and for resolving tensions between local and global dynamics.

A new rural-urban social contract

Moreover, as Patrick Caron says: “the 2030 Agenda for Sustainable Development relies on flourishing rural areas. The interdependence of rural and urban areas must be acknowledged and used as the basis for a new rural-urban social contract. This would lay the foundations for a civilization that pays its rural areas and their inhabitants for the functions they fulfil and the public goods (commons) they provide for societies, the planet and economies.”
