1. Food system drivers?
Any actor or factor or policy framework which push or shape the food system, internally or externally can be the drivers of the food system. Key drivers include demographics, socio-economic-cultural, technology, policies and environment.
2. Food system activities and actors
Sustainable food systems are interconnected and represent the full agri-value chain, from pre-production and production to supply chains and consumption:
a. PRE-PRODUCTION
The sustainability of a food system begins well before a crop is grown or an animal raised. This “pre-production” stage includes how genetic resources are conserved and used to improve the quality and productivity of domesticated crops and livestock for the future. It also includes innovations in agricultural inputs, such as fertilizer or crop protection products. These can help to boost yields and incomes while preventing further land from being converted for cultivation. And it also includes advances in agricultural practices themselves to ensure that farmers can continue to thrive in the face of climate change and other increasingly unpredictable conditions.
b. PRODUCTION
In the “production” stage, farmers must contend with the myriad challenges involved in growing and harvesting, including pests and disease, severe and unpredictable weather, food loss management and fluctuating market conditions. Under current projections, 60 per cent more food will be needed by 2050, yet current production efforts are falling short of this target and global hunger levels are on the rise again after decades of progress. This is in addition to the two billion people already suffering from malnutrition globally today.
c. SUPPLY CHAIN
The “supply chain” stage refers to the steps taken to deliver food from the farmer to the consumer. Transformed into sellable goods, these products can be processed, packaged and stored before eventually being transported to market. Post-harvest food loss is an especially important issue across the developing world, where the infrastructure, energy grids and transport systems are often poor or missing. In these countries, more than 40 per cent of food losses occur post-harvest and during processing.
d. CONSUMPTION
A food system does not only capture how something is grown; it also includes how a food is cooked, eaten and disposed of by consumers. During this “consumption” stage, each of us makes a series of decisions, which have broader implications to our food and nutrition security, the well-being of our communities and to the wider environment and natural resource base. Some high-income countries spend less than 10 per cent of income on buying food while others, mostly in Africa and Asia, spend more than 40 per cent. Likewise, while some countries are facing obesity epidemics, others suffer from the impacts of undernutrition.
3. The sustainable food system’s outcomes?
-
Delivering affordable, nutritionally adequate, safe and healthy (and even culturally or religiously acceptable) food is a necessary but not sufficient condition for a food system to be sustainable;
-
To be sustainable a food system also needs to aim at reducing food waste and food losses and at minimizing its present and future impacts on the environment and society;
-
In that regard, we see the balance and the trade-offs between agro-ecosystems integrity and social well-being as being at the core of sustainable food systems;
-
By definition the sustainability of a food system is locally (and possibly timely) determined. There is no such thing as a global sustainable food system.
