"The Sustainable Intensification of Agriculture: Progress and Principles for Redesign"

Sustainable intensification is defined as a process or system in which yields are increased without adverse environmental impact and without the cultivation of more land. It emphasizes ends rather than means, and does not predetermine technologies, species mix, or particular design components. Its expansion has begun to occur at scale across a wide range of agroecosystems. The benefits of both scientific and farmer input into technologies and practices that combine crops and animals with appropriate agroecological and agronomic management are increasingly evident.

Jules Pretty's opening keynote presentation, “The Sustainable Intensification of Agriculture: Progress and Principles for Redesign”, draws on the three stages of transitions towards sustainability: i) efficiency; ii) substitution; and iii) redesign. Sustainable intensification of agriculture will be a continuous journey of adaptation and improvement, driven by a wide range of actors in the agricultural knowledge economy. As we develop clearer targets, progress toward redesign could be a gamechanger with wide social benefits.

Meagan Schipanski Photo

Meagan Schipanski is an Assistant Professor of agroecology in the Department of Soil and Crop Sciences at Colorado State University. She earned a B.A. from Oberlin College and Ph.D. from Cornell University. Her research group applies systems-based approaches to improving the resilience of cropping systems, including topics of crop diversity, soil health, nutrient and water management, and climate change adaptation strategies. Her work spans from on-farm research to greenhouse and modeling studies. Due to the critical role social and economic systems play in shaping agriculture, she also collaborates on broader, multi-disciplinary food systems research.

Designing Agricultural Systems for Resilience Through Partnerships Among Plants and People

Increasing crop and non-crop plant diversity can improve the resilience of agricultural systems. Resilient systems maintain productivity and internal nutrient and pest regulation capacity in the face of shocks and stressors. In addition, resilience includes empowering producers to innovate and adapt systems through time. I will review the opportunities and potential limits for using plant diversity to improve resilience of agricultural systems across different climates. I will also highlight opportunities and barriers to the adoption of more diverse cropping systems using examples of regional, multi-disciplinary collaborations evaluating agricultural policies and whole food systems.

"Do My Efforts Have An Impact?"

Impact materializes when our efforts are a ‘means to an end’ instead of an ‘end in themselves’.  Impact results when our efforts drive new scientific approach, stimulate students to think and learn to solve problems, or when they directly affect the consumer.  The impact of our efforts in all aspects of science depends to a large degree on how well we followed the scientific process.  Did we think ‘outside the box’ when we developed our hypothesis?  This can be risky, but many times it results in major breakthroughs.  I have a little plaque on my desk that says “Only those that see the invisible can do the impossible”.  Another stumbling block that limits impact is poor planning.  Involving multiple disciplines to formulate diverse ideas and approaches can help to make the most efficient use of funds to make the broadest impact.  Larger teams are also more likely to obtain grants.  We often do a fairly good job of conducting the research, analyzing the data, and publishing the results, but serendipity should be treated like a gift and not ignored!  At times we are not as effective as we could be in conveying our findings to taxpayers and consumers, or moving our efforts to the next step through advanced research.  Although it often becomes easier to build our impact factor after the first major success has been made, we could all benefit from a course on how to be a salesperson.  Remember, we have not learned the best way to do anything yet.  There is always a better way, but it is up to us to find it.

"Peanuts, Turf, and Public Understanding: A Systematic Approach to Crop Research and Outreach"

This presentation will focus on our challenge of serving the greater needs of society through agricultural research and being responsive to society’s frequent mistrust and isolation from agriculture and science.  While the public’s concerns over pesticide use in urban environments and the challenges of subsistence agriculture in sub Saharan Africa seem disconnected; they all have a significant focus on risk. Our systems approach to research provides for a safe and secure food system, however, we’ve seen recent trends for a significant portion of the public to embrace science denialism. This creates potential challenges for scientists who serve as educators and researchers, and not as advocates. Diverse commodity responsibilities and unique clientele characteristics across large expanses of agricultural and social communities can bring unique perspectives regarding communicating science to the public. My involvement in programming to address societal fears about science has been enlightening yet frustrating.  Examples and case studies of how peanut research provides value for turf programming and how projects in Africa have contributed to addressing societal issues in the U.S. will be presented.

"Mining Infinitesimal Effect Alleles in Maize"

The use of genetic information to predict the value of individuals in plant breeding populations began about 40 years ago. ‘Allele mining’ is an approach that identifies genomic regions affecting traits, discovers new allelic variation in the underlying genes, and uses allele-specific or linked genetic markers to select individuals carrying the desired allelic variants in breeding populations. Thousands of quantitative trait loci and marker-trait associations have been reported across many species. The practical use of these associations greatly lags behind their discoveries because individual markers are often associated with only a small proportion of genetic variation, such that their value in selection is small. In a few lucky cases, individual genes with very large effects on important traits were discovered, and these could be more easily turned into useful selection targets. Genomic selection was proposed by animal breeders as a way to more effectively use the information contained in dense genetic marker sets for the prediction of quantitative traits. Crop breeders subsequently discovered that this approach could be generalized across the diverse population structures and mating systems of plants and have begun implementing genomic selection in crops with success. The polygenic nature of many important traits in maize complicates genetics-based approaches to incorporating favorable novel alleles from diverse but unadapted genetic resources.

She is currently a Monitoring Editor for Plant Physiology.  Dr. Kellogg also holds adjunct appointments at Washington University in St. Louis and the University of Missouri-St. Louis.

"Looking in Wild Places: Crop Relatives and Pasteur’s Quadrant"

Study of wild grasses falls firmly in the realm of use-inspired basic research (also known as Pasteur’s quadrant).  All crops grown by humans have been selected from wild species, and often bear flowers and fruits that are similar to their wild ancestors.  Study of wild species thus provide insights and hypotheses that can be tested in crops.  This talk will focus on recent work on the wild relatives of sorghum and Miscanthus, including the plants of the tallgrass prairie and the great grasslands of Africa.  All these plants bear their flowers in tiny clusters (spikelets); the spikelets themselves are borne in sets of two but only one of the pair makes a seed.  The production of sterile flowers is paradoxical because it would seem to be a waste of resources.  Most species also have an extension of the floral bract (awn).  Investigating how the spikelets and awns function in wild species, we have found that that they have novel roles in growth and seed set (yield).  These results then inspired experiments and new results in cultivated sorghum.

"Accelerating Innovation in Soil and Nutrient Management"

This lecture will provide a vision for speeding up innovation in soil and nutrient management. The new Sustainable Development agenda requires tailored, integrated solutions that ensure greater precision and efficiency in managing soils and nutrients along the whole food chain. Despite incremental progress made in past decades, the general paradigms and methods for how we assess soils and translate that information, along with other data, into recommendations for nutrient management have changed little. Limitations that are inherent to this approach constrain its future applicability, particularly also for making faster progress in developing countries. New thinking and new diagnostic technologies now provide an opportunity to shift the traditional paradigms towards data-driven know-how solutions for nutrient management. Exploiting these opportunities will require a leaner, faster science and innovation culture that can take full advantage of advances in many disciplines. It will also require new models for public-private partnership, generally following a more collaborative and open innovation culture.
