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.
