Agroecosystems can be defined spatially as individual crops or farms. They occupy
approximately 35% of the ice-free land area. Biodiversity varies
from enhanced to impoverished in comparison to the pristine systems
that were converted to agriculture. Agroecosystems are important
in our daily lives, and have significant impacts on adjacent ecosystems
and on global ecological processes, yet they are largely overlooked
in most university biology curricula. This site provides an overview
of agriculture, viewed from an ecosystems perspective, and a gateway
to more detailed information.
This site is maintained by the Agroecosystems class (Biology 3068) at Dalhousie University, Nova
