Precision Agriculture and the Diversity-Stability Hypothesis

The benefit of precision agriculture must be defined both in terms of profitability as well as environmental enhancement.  Maintaining biodiversity within the landscape is central to the protection of ecosystem services.  The diversity-stability hypothesis suggests that there is a positive correlation between increasing diversity and ecosystem stability. In this context, diversity is defined within the context of species richness, strength of community interactions and functional traits.   In this presentation, I will explore the diversity-stability hypothesis and illustrate how precision agriculture can play a pivotal role in identifying opportunities to enhance biodiversity within our agricultural production system.   The fundamental question that drives this research is, “How resistant or resilient are our agroecosystems to stress, such as climate change?"   The transition of yield maps to profitability maps can play a major role in identifying areas within a field that are consistently areas of economic loss.  Identification of these areas allows for the possibility of converting this land base to the protection of ecosystem services via the enhancement of biodiversity.   There is, however, a general perception within the agricultural community that ecological and environmental conservation will equate into a loss of on-farm profitability.  Profitability mapping may allow this perception to transition to an "enhancement in profitability” through ecological and environmental conservation.   In addition, the agricultural industry is being pressured to respond to national and international market demands such as,”How green is your product?  What is the carbon foot print of your production practices?"  Consumer preferences are influenced highly by environmental issues.  How then does a farmer or a country protect his/her "market brand".  Precision agriculture can play an important role in helping to address these issues. Knowledge generated by precision agriculture can be used to connect linkages with ecology and agronomy.   Such linkages will enhance ecosystem stability, on farm profitability and protect access to national and international markets.
