abstract = "The changing climate leads to uncertainties concerning the
sustainability of certain agricultural resources, and with the
additional stresses of an increasing global population,
uncertainty in food security will greatly increase. To adhere to
future food demands in the face of this changing climate,
perennial agriculture has been a proposed solution. However, it is
equally important to assure that perennial agriculture is not
negatively affecting the climate in exchange for this proposed
more robust food source. We chose to examine the interactions
between perennial and annual agricultural crops by focusing on the
efficiency of exchanges with the atmosphere. This is done using
the omega decoupling factor for 4 different sites as a way of
quantifying the contributions of radiation and stomatal
conductance over the resulting water and carbon cycles. This gives
us an indication of how the plant canopy is interacting with, and
influencing the local microclimate. Ultimately, this should give
us an indication of the ability of perennial crops to aid in the
climate mitigation process. We hypothesized that the perennial
site chosen would have omega values more similar to the omega
values of a natural grassland rather than an annual crop site.
Using AmeriFlux towers to determine the canopy values needed to
calculate the omega decoupling factor, we focused on the Kernza
perennial crops being grown at the Land Institute in Salina,
Kansas (KLS), in comparison to a natural grassland in Manhattan,
Kansas (KON), a typical land cover model in Lawrence, Kansas
(KFS), and an annual crop site in Lamont, Oklahoma (ARM). These
results will allow us to move forward in the investigation of
perennial crops as a sustainable food source.",
