FooD SUPPLY AS A GLOBAL CHALLENGE 197
  
animal husbandry (the emission of harmful substances and water consumption,
 as well as aspects of animal welfare).
 
However, a vegetarian diet or the growing, selling and consumption of bio
 products do not offer solutions to the systemic problems that have been identified
 as the greatest challenges in the global food system. Soy, which is of decisive
 importance for bio products and a vegan diet, also travels halfway around the
 globe, like any other food item. Vegetables and fruits produced with industrial
 methods can be as harmful to health and the environment as a traditional diet.
 Changing individual eating habits does mean a step towards sustainability, but it
 leaves the systemic problems unchanged, and more importantly, it often leaves
 them unproblematized. In the review of systemic alternatives given below, we wish
 to draw the reader’s attention to existing theories and practices which may help,
 either alone or together, to solve such fundamental problems as having control
 over our food, settling the relations between humans and nature, or linking expressly
 agro-technical questions to the social conditions with which they are interlinked.
 
 
Systemic alternatives in food provisioning
  
In response to the challenges of the 60s and 70s, several green movements evolved.
 Among these, bioregionalism, agroecology and permaculture will be discussed
 here. While bioregionalism emphasizes geographical organization, the tools for
 the systemic transformation of the food system are developed in permaculture and
 agroecology. Agroecology and permaculture can be interpreted in the food
 sovereignty framework which evolved in the 90s in equal measure.
  
Food sovereignty is a political framework which points out the systemic challenges
 generated by globalized food systems. It seeks possibilities of resistance and the
 systemic transformation of food provisioning (Patel 2007; McMichael 2008). As
 a movement, food sovereignty takes a stand against the Green Revolution and the
 dominance of industrial agricultural practices, neoliberal free trade policies
 (particularly the dumping of agricultural surplus into foreign markets), and the
 undemocratic governance of food and agricultural trade (particularly the
 organizational structure and rules of the WTO) (Carlile et al. 2021).
 
The framework emerged as a result of the ongoing internal dialogues of rural
 social movements in the early 1990s and was introduced by La Via Campesina
 (founded in 1993) at the FAO food summit in 1996. La Via Campesina is an
 international social movement of nearly 200 organizations from 81 countries,
 divided into national, regional and continental units. It represents the interests
 of farming families, peasants, indigenous people, landless peasants, agricultural
 laborers, rural women, and young people, totalling some 200 million families
 across the world (Martinez-Torres — Rosset 2014). The public forums organized
 in parallel with the FAO World Food Summits in 1996 and 2002 served as
 important venues for the strengthening of the food sovereignty movement.
 Food sovereignty was a consensually accepted narrative used by NGOs
