Report Proposes Microbiology's Grand Challenge to Help Feed the World
"Microbes are essential partners in all aspects of plant physiology, but
human efforts to improve plant productivity have focused solely on the
plant," says Ian Sanders of University of Lausanne, chair of the
colloquium that produced the report. "Optimizing the microbial
communities that live in, on and around plants, can substantially reduce
the need for chemical fertilizers, pesticides and herbicides."
The report, How Microbes can Help Feed the World, is based on the
deliberation of a group of scientific experts who gathered for two days
in Washington DC in December 2012 to consider a series of questions
regarding how plant-microbe interactions could be employed to boost
agricultural productivity in an environmentally and economically
responsible way.
It starts with a startling statistic: In order to feed the estimated
global population of 9 billion in the year 2050, agricultural yields
will have to increase by 70-100% .
Improved understanding of plant-microbe interactions has the potential
to increase crop productivity by 20% while reducing fertilizer and
pesticide requirements by 20%, within 20 years, according to the report.
These estimates rest on the recognition that all plants rely on
microbial partners to secure nutrients, deter pathogens and resist
environmental stress.
The report looks in depth at the intimate relationship between microbes
and agriculture including why plants need microbes, what types of
microbes they need, how they interact and the scientific challenges
posed by the current state of knowledge. It then makes a series of
recommendations, including greater investment in research, the taking on
of one or more grand challenges such as characterization of the complete
microbiome of one important crop plant, and the establishment of a
formal process for moving scientific discoveries from the lab to the field.
"New technologies are making plant-microbe ecosystems easier to study
and investment in this area of research could have dramatic benefits,"
says Marilynn Roossinck, Pennsylvania State University, who helped
organize the colloquium.
