Marian, I learned of your vision from Saskia Visser and read it because of my own interests in sustainable food systems. I was very impressed with your Food Connects 2050 vision. I really like your concept for several reasons. It focuses on food in urban areas where diversity in incomes and quality of life are huge, and where food deserts occur in poor areas. Even now, as you point out, there are urban food deserts in which people living in them lack access to food and nutrition. This is true in Washington, DC and many other large cities in the USA. These depressed areas will certainly grow in the future as our cities continue to grow unless they are addressed. There are large inequities that must be addressed; these will only get worse unless sustainable solutions are found.
Other reasons that I like the proposal are that the concept being proposed is guided by principles of circular food economies, and the design of community-based initiatives should help instill pride within members of the communities involved. People in these urban areas must not only be involved, but they must take ownership of the solutions in order for them to be acceptable and socially and economically sustainable.
