Sometimes I volunteer at an urban farm.
In what way? Urban agriculture can involve many things, including animal husbandry, aquaculture and agroforestry.
Yes, the one I volunteer at has a lot of aquaculture.
That would imply that you farmed fish, crustaceans, molluscs or aquatic plants. True?
Yes, I farmed fish and aquatic plants.
Another interesting aspect of Urban agriculture is how it can reflect different levels of economic and social development.
The urban farm I go to is in the worst part of town. They are doing it there to try to rebuild the community.
Another example of that is Gateway Greening in St. Louis, Missouri, which works to educate and empower its community.
