Yes, Africa will feed itself within the next 15 years

Africa will be able to feed itself in the next 15 years. That’s one of the big “bets on the future” that Bill and Melinda Gates have made in their foundation’s latest annual letter. Helped by other breakthroughs in health, mobile banking and education, they argue that the lives of people in poor countries “will improve faster in the next 15 years than at any other time in history”.

Their “bet” is good news for African agriculture: agronomy and its natural twin, agricultural extension, are back on the agenda. If Africa is to feed itself, the women and men who grow its crops need access to technical expertise on how to manage their variable natural resources and limited inputs and market intelligence on what to grow, what to sell and what to keep.

New tools in the hands of farmers

The Gates foundation report outlines that African countries spend $50 billion a year importing food. Nigeria alone imports $500m of rice from Vietnam each year.

But there is no quick fix that will transform African agriculture without skillful agronomy and intelligent extension. Whatever the promises brought by new, drought-tolerant varieties of crops such as maize, they cannot achieve their potential without the wise management of fertilisers, timing of cultivations and appropriate crop rotations.

Bill & Melinda Gates Foundation 

As the graph above shows, sub-Saharan Africa’s crop yields remain very low compared to the rest of the world. Sadly, in our rush for only genetic solutions to increasing agricultural yields, we have ignored the fields and landscapes in which crops are grown. The consequence has been a missing generation of scientifically trained agronomists and agricultural extension workers – who help teach farmers about new farming practices – with the skill sets required to manage resources and apply principles.

Meanwhile, powerful tools such as geospatial mapping, predictive modelling, remote-sensing (using aerial imaging to assess the state of vegetation) and mobile technologies have advanced to a stage where they are of practical use to the scientific agronomist, educated extensionist and literate farmer. We now have a real opportunity to link genetic advances and improved management with the social and economic drivers for African agriculture. This “research value chain” between grower and consumer requires that each research discipline plays an interconnected role with the end-user always in sharp focus.

Soils and sustainability

So, what are the priorities for African agriculture in the next 15 years? First, we must rehabilitate its soils. Since 2015 has been declared as the UN International Year of Soil, we need to recognise that Africa has some of the world’s frailest soils, which have suffered most from “cereal abuse” through the almost continuous cultivation of cereal crops. These monocultures have left Africa’s soils tired and impoverished. Applications of fertilisers will not, by themselves, be enough to save them.

For sustainable agricultural systems, we need to reconsider our addiction to major cereals grown as monocultures and move from “calorie security” to “nutritional security”. For this, nitrogen-fixing leguminous crops have to be part of any solution. In his Noble Peace Prize address in 1970, Norman Borlaug, the father of what became known as the “green revolution” in South Asia, recognised the imbalance between research advances on the major cereals and those on all other crops:

The only crops which have been appreciably affected up to the present time are wheat, rice, and maize… nor has there been any appreciable increase in yield or production of the pulse or legume crops, which are essential in the diets of cereal-consuming populations.

Approaching 50 years later, the situation remains similar. Clearly, improvements in leguminous crops (such as beans and lentils), both in their own right as nutritious sources of food and as rehabilitators of soil, are long overdue. Since 2016 has been declared as the UN International Year of Pulses, there is no better opportunity to redress the historical imbalance noted by Borlaug.

Crops for the future

We also need to recognise that most African family farmers are women. Often the species they cultivate are not the major cash crops grown by men as mechanised monocultures. Rather, they are local “underutilised” species, often legumes and vegetables, which families cultivate in complex landscapes for their own sustenance.

These crops, and the multiple cropping systems which support them, have few influential champions and rarely feature in the research strategies of national and international agencies. But it is crops and agricultural systems such as these that will help Africa feed itself sustainably.

In a very real sense, these “crops for the future” will help diversify Africa’s agriculture to meet the volatile physical and economic climates that lie ahead. Unlike the major crops which have received billions of dollars of support over generations, underutilised crops deserve a “big bet” over the next 15 years if they are to help achieve major breakthroughs for most people in most poor countries.

B.B. Singh’s quest to make cowpea the food legume of the 21st century

4fig3In 1944, the year Bir Bahadur (B.B.) Singh was born in the state of Uttar Pradesh in India, Indian agriculture was in shambles. During nearly 200 years of British rule, the country’s agricultural enterprise had been turned over to commodities such as cotton, indigo, and sugarcane for export; what little food was grown hinged on rainfall and the soil’s natural fertility—or lack of it. Crop yields were often abysmal as a result, and famine was common. So when India won independence from Britain in 1947, the Indian government enacted a sweeping program of nationwide, agricultural education.

That’s why when Singh graduated in 1956 from his village school with good grades and an interest in science, he found himself at one of India’s newly minted agricultural high schools. It was the only nearby school where he could study science, Singh says, as well as the closest high school to his home. Plus, his father wanted him to attend, saying, “Why don’t you study agriculture and see what help you can give to our people,” Singh recalls.

“So I was okay with going to an agricultural high school, and that later became my good luck,” he says. Turns out it also became the good luck of millions of the world’s smallholder farmers.

Today, Singh is among the most revered breeders of legume—or pulse—crops, credited with improving the diets, incomes, and lives of farming families across Africa, Asia, and South America. In the late 1960s and 1970s, for instance, the ASA and CSSA Fellow not only established the first systematic breeding program for soybean in India, but was also pivotal in bringing the novel food to millions of Indian people. Soybean production has since grown in India from just 5,000 tons in 1961 to about 12 million today. Yet this was only the start.

“Of course, B.B. is best known for his work with cowpea,” says Bill Payne, an ASA, CSSA, and SSSA Fellow who was at Texas A&M and CGIAR in Ethiopia before becoming dean of agriculture at the University of Nevada–Reno this winter. “Almost anywhere in the world, you cannot work on cowpea without running into him in some way, fashion, or form.”

imagesKnown also as black-eyed pea, cowpea is a staple crop in many tropical areas, and Singh’s signature achievement is a fast-maturing variety that fits into the rotational niches between wheat, maize, and rice. Due largely to this advance, worldwide cowpea production rose from 1.3 million to 7 million tons between 1981 and 2013—the only food legume to enjoy such an upswing. But the crop scientist, now in the 48th year of his career, isn’t content to stop there.

“I think there’s a very good possibility that we will have a surge in pulse production in the coming decades,” says Singh, who currently splits his time between Texas A&M University and India’s G.B. Pant University. The title of his new book, Cowpea—The Food Legume of the 21st Century asserts the same.

Those who know him don’t doubt it. “He’s just tenacious,” says CSSA President David Baltensperger, also an ASA and CSSA Fellow. He often compares Singh’s success with cowpea to Norman Borlaug’s accomplishments with wheat. “One of the secrets to B.B., like Dr. Borlaug, has been his ability to keep his eye on what he considers to be really powerful fundamentals. That leads to a lot of success over a long career.”

Good decisions… and a little luck

Focus is indeed crucial for a researcher, and other colleagues add that Singh is highly intelligent, full of energy, and a careful listener—as well as supremely dedicated to helping farmers.

“He is an excellent scientist—I mean, he publishes a lot,” says Ken Dashiell of the International Institute of Tropical Agriculture (IITA) in Ibadan, Nigeria, from which Singh retired in 2006. “But he probably spends 98% of his energy on getting the best cowpea varieties for the farmers, and 2% of his energy on publishing.”

What Singh himself says is that he’s been lucky. “At every stage of my life, some good people have come, given me direction, and good things have happened,” he says. The first stroke of luck came when his father pushed him toward an agricultural high school because it helped gain him admission in 1960 to India’s first agricultural university: Uttar Pradesh Agricultural University (now Pant University).

4fig3Singh then earned a scholarship in 1963 to do graduate studies in plant breeding at the University of Illinois, where again he made a fateful choice. After learning how much research was already under way to improve cereals, Singh resolved to study legumes to help India’s vegetarian multitudes meet their need for protein. And at the University of Illinois, that meant one option: soybean.

“So, that’s how I decided to work on soybean,” he says, “and it was one of the best decisions that I took in my life.”

Soybean contains roughly twice the protein of other pulses, he explains, and by the time he earned his Ph.D., USAID and the University of Illinois were already trying to bring soybean to countries beset by malnutrition, including India. Meanwhile, the dean of agriculture at Pant University was monitoring Singh’s progress, and in 1968 sent him a “very personal and emotional letter,” Singh says. It offered him—now a postdoc at Cornell—an assistant professorship at Pant that included 50% more salary than what a new assistant professor in India typically earned.

Singh had two competing offers from U.S. universities for substantially higher pay, but he never gave the decision a second thought. Later that year, he returned to India to begin the work that would transform soybean from an agricultural novelty into one of the nation’s principal foods.

He might have stayed at Pant for the rest of his career. But in 1977, a change in university administration led to major campus unrest, including the shooting of several staff. Hoping to get away for a “breathing spell,” Singh began looking for other opportunities and was immediately offered soybean breeding positions by the United Nation’s Food and Agriculture Organization (FAO) in Zambia and by IITA in Nigeria. Opting for IITA because of his interest in research, he intended to stay abroad for just two years, but “then based on my work, they kept me there forever, and I spent my life there,” he says.

They asked something else of him, as well: to work not on soybean, but cowpea.

Cellulosic Ethanol from Sugarcane in Brazil

sugarcane fieldBrazil is a major producer of ethanol from sugarcane, and this leading global position is the fruit of scientific and technological advances resulting from a development program that was initiated in the 1970s. Driven by the oil crises of 1972-1973, Brazil transformed several sugar mills into ethanol producing units that became capable of co-production of ethanol and raw sugar (5). This was technically possible due to the high levels of sucrose in sugarcane and to the development of yeast strains capable of fermenting this sugar efficiently. At the same time, the first automobiles running exclusively on ethanol were introduced, which on the one hand helped Brazil face major world energy crises, and on the other implanted the basis for development of future technologies. Over the following 40 years, Brazilian sugar mills undertook a technological transformation that significantly increased the efficiency of sucrose and alcohol production. This method, now called first generation (1G), has reached a level of 90% conversion of sucrose into ethanol (5). At the same time, advances in sugarcane agricultural technology improved the sugarcane crop to a high level of productivity (averaging 80 tones per hectare). Using intensive breeding programs, a number of sugarcane varieties have been developed that are increasingly better adapted to the diverse climate and soils encountered in Brazil. The result is that Brazil is now the second largest producer of ethanol and the first placed producer of sugarcane in the world.

The necessity to produce second-generation ethanol

Until 2006, Brazil was the only country to produce and use ethanol on a large scale as a fuel alternative for cars. Since then, increased public awareness and governmental focus around the world on issues related to climate change and the excessive use of fossil fuels has led to increased interest in the use of renewable energy. It was at this moment that Brazil, with its highly efficient sugarcane bioethanol sector, became a leader worldwide in the production and use of renewable energy. Nevertheless, production of 1G bioethanol was already at the limit of efficiency both from industrial and agronomical viewpoints.

It was in this context that the Brazilian scientific community and the Federal and State of São Paulo governments took the initiative in the search for ways to increase production of sugarcane ethanol beyond current limits. An idea that was already being revived in several places in the world was the possibility to produce ethanol from sugar polymers, including cellulose, present in cell walls of plants. This search for ‘cellulosic ethanol’ is generally referred to as second-generation (2G) ethanol. Although establishment of 1G technology was highly successful, the potential for ethanol production from 2G is much higher because energy accumulated in sugarcane in the form of sucrose represents only 1/3 of the total. The other two-thirds are distributed equally between the bagasse (stems) and the leaves.

Cell wall recalcitrance

At first sight, the idea of producing ethanol from biomass seems straightforward: it would be enough to convert cellulose to free sugars that could be fermented by yeast. Although many advances have been made in this area, this problem is far from being solved, and developing 2G processes that are economically viable has proven to be a major challenge. The plant cell wall is composed mainly of carbohydrates in the form of polysaccharides that associate to form a supramolecular structure where polymers aggregate through non-covalent linkages. Some polysaccharides are branched with phenolic compounds (ferulic an p-coumaric acids). Ferulic acid can dimerize interlocking polysaccharide chains or these can still undergo polymerization with other phenylpropanoids, including p-hydrocinammic, sinapyl and coniferyl alcohols, forming lignin. Together, the supramolecular structure of cell-wall polymers constitute the main obstacle to enzymatic hydrolysis. Furthermore, known hydrolytic enzymes have molecular sizes that prevent their penetration into the polymer matrix. Therefore, when a mixture of enzymes is added to the surface of the cell wall, the catalytic attack is mainly on the surface of the composite. To perform more complete hydrolysis, enzymatic complexes would have to act in a synergetic fashion on the entire cell wall composite. At present this is not feasible as researchers cannot adequately control the process because very little is known about the synergism between the enzymes involved. One of the principal limitations to understand such mechanisms is that until recently our knowledge of the structure and architecture of the sugarcane cell wall was very limited.

Sugarcane buckAt the biological level, cell wall recalcitrance in plants is thought to be due to the wall’ ability to protect against herbivores and the penetration of pathogens. At the molecular level, the cell wall of sugarcane presents three domains of polysaccharides that interact through non-covalent linkages: the pectic domain, the hemicellulosic domain and the cellulosic domain. The cellulosic domain is embedded within the hemicellulosic domain and both are embedded in the pectin domain. Thus, the basic unit of the cell wall of sugarcane consists of a core with macrofibrils (agglomerated of microfibrils) of cellulose strongly linked to structurally complex hemicelluloses that display a glycomic code, the complex branching pattern of these compounds (2). In addition, this core of polysaccharides is surrounded by an agglomerate of polymers that interact with themselves. Phenolic compounds are also thought to interlock the three polysaccharide domains so that the covalent linkages are protected, effectively sealing the whole unit and creating a structure that is extremely resistant to mechanical, chemical and biochemical degradation.

Several publications produced by the research labs of the National Institute of Science and Technology of Bioethanol (INCT-Bioetanol – www.inctdobioetanol.com.br) have demonstrated that it is possible to disassemble the cell wall using chemical reagents (4). The procedure consists of initially attacking the phenolic compounds and eliminating them from the wall. This makes subsequent separation of the wall polysaccharides possible via treatment with a series of alkali solutions of increasing concentration (6).

A procedure called pretreatment (chemical and physical treatments with hot water, ammonia, acids and/alkali), eliminates the porosity barrier so that all polymers become accessible to attack by hydrolases. However, the branching nature of hemicelluloses still acts as a barrier and prevents further enzyme attack of the polymer chains. This highlights the necessity of using specific enzymatic complexes in order to produce free sugars that can be utilized for fermentation (1-7). As branched hemicelluloses alter the way polysaccharides are recognized by enzymes, their branching pattern (glycomic code) can alter the interaction between enzyme and substrate, affecting enzyme kinetics and cell wall degradation efficiency. The available data shows that the cell wall of sugarcane displays at least 18 glycosidic linkages, and suggests that approximately the same number of enzymes will be necessary to degrade the cell wall completely (5,6). Nevertheless, this chemical process is extremely complicated, laborious and expensive, and this is therefore not a viable strategy for industry.

The collection of enzymes characterized during the first phase of the INCT-Bioetanol contains practically all the catalytic capabilities needed for complete sugarcane cell wall hydrolysis. For this reason, the Institute has reached a point of prioritizing experiments focused on combining enzymes, forming consortia capable of dealing with each of the limiting factors related to recalcitrance. The possible combinations of enzymes have been proposed (1,6) and during the next phase of the project, these strategies will be put into practice by an integrated group of researchers in a series of experiments that will test this hypothesis.

At the same time, it will be necessary to understand the variability in the structure of the sugarcane cell wall in order to find Brazilian sugarcane varieties possessing structures and architectures that are more amenable to hydrolysis. Although the variation in cell wall composition is relatively limited among sugarcane tissues, one may expect to find considerable variation among the great number of extant varieties. This has been recently observed for Miscanthus and maize, two grass species that are genetically related to sugarcane and with very similar cell walls. Several research groups have concentrated efforts on understanding the role of lignin in recalcitrance and have concluded that this interference is somewhat limited. The reduction in lignin content leads in general to an increase in saccharification in a non-linear fashion depending on the pre-treatment, morphological distribution and the level of lignin aggregation (9), suggesting that other cell wall domains make equally important contributions to the recalcitrance of biomass. Research groups of the INCT-Bioetanol have already obtained transformed sugarcane in which the gene encoding one of the enzymes of lignin biosynthesis (COMT) has been silenced. These transgenic plants have cell walls that are modified, and saccharification tests are currently in progress. During the second phase of the INCT we intend to verify whether such genetic variability also exists in sugarcane and to use this information to obtain varieties in which differences among cell wall composition lead to lower recalcitrance to hydrolysis.

Onwards and Upwards for the Global Plant Council

PrintThe 2014 Global Plant Council annual general meeting (AGM) was held 2-3 October and hosted by the Society of Experimental Biology in London. GPC Individuals representing 22 member organisations from 5 continents gathered at Charles Darwin House to share updates and plan for the future.

The Global Plant Council (GPC) is a coalition of plant and crop science societies from across the globe. It aims to provide a global voice for these societies which individually represent scientists from specific countries, continents or sub-sets of plant science. During the AGM it became clear that in reality the GPC is a central hub, acting to instigate change in plant science research and application worldwide. This is a critical role; coordinated global action and a unified voice are essential for plant scientists to be able to effectively play a part in meeting the world challenges of hunger, energy, climate change, health and well-being, sustainability and environmental protection, which affect all of us.

The first day of the AGM was dedicated to sharing news and updates. Two working groups, that deal with Advocacy and Finance issues, praised the progress made by Ruth Bastow, the GPC’s first dedicated member of staff, since May 2013. Council members were pleased to see GPC flyers and brochures designed, produced and distributed at conferences over the summer, resulted in over 140 people signing up to join the GPC mailing list (if you don’t receive the monthly bulletin then sign up here!). The GPC blog had a successful launch in April 2014, with a particular highlight being a post on the economics of agricultural biotechnology by David Zilberman.

At the 2013 AGM, member organisations identified four priority areas: Agricultural Productivity and Sustainability; Food and Human Health; Adaption to Climate Change; and the sharing of Knowledge, Data and Resources. The GPC will support and promote these themes through activities including network building, engaging with policy makers, fundraising and leading global collaborative projects.

Recent activities for the GPC have focussed on number of key initiatives: Diversity Seek, Digital Seed Bank, Biofortification and Stress Resilience.

The Diversity Seek Initiative is a community-driven initiative that has been established in collaboration with the Global Crop Diversity Trust, the Secretariat of the International Treaty on Plant Genetic Resources for Food and Agriculture, the CGIAR Consortium and the GPC. Approximately seven million crop accessions are being conserved worldwide, representing one of the greatest – largely untapped – opportunities for accelerating yield gains and overcoming emerging crop productivity bottlenecks. DivSeek acts a ‘magnet’ to bring together current and future projects working toward unlocking and characterizing the crop diversity that exists in genebanks around the world in a coordinated manner. The DivSeek Initiative was presented and discussed at the recent G20 meeting of Chief Agricultural Scientists in Brisbane, Australia and is noted in the final communiqué from the meeting.

The Digital Seed Bank is a foundational DivSeek project and will act as a ‘flagship’ to illustrate the power of mining the genetic potential of crop diversity. The Digital Seed Bank will store detailed information on the molecular and biochemical basis of genotype x environment interactions, and allelic diversity, and will utilize this data to discover the gene networks controlling quantitative traits for yield and quality performance. Combining genomic data with quantitative information about the expression of genes, proteins, and metabolites from crops growing in environmental conditions that reflect their diversity will give breeders unprecedented new and valuable insights that can be exploited for crop improvement programs. The Digital Seed Bank initiative leader Wilhelm Gruissem is currently seeking funding to make the Digital Seed Bank a reality.

In July, the GPC gathered 30 scientists from 11 countries (including representatives from Africa, Africa, Europe, Oceania and the Americas) for a Forum focussing on the Biofortification Initiative in Xiamen, China. Attendees at the Forum considered current projects, assessed current strategic investments into R&D, and initiated a gap analysis to begin the process of ensuring that major nutritional needs are met through an internationally coordinated approach. The outcomes of this workshop will be summarized in a white paper that will be made available via the GPC website.

The final initiative is improving Stress Resilence. The initiative leaders are planning holding their first forum at the 2015 International Plant Molecular Biology Congress at Iguazu Falls, Brazil in October 2015. We’ll keep you informed as more details get finalised.

New initiatives were discussed at the AGM, from a digital resource to international research projects to engaging with global policy bodies. The Global Plant Council has made vast progress in the past two years – and there is much more still to come!
