CASSAVA: HOW PLANT SCIENCE IS HELPING IMPROVE THIS STAPLE CROP

Today, PLANT SCIENCE INNOVATIONS are making staple crops more profitable, more nutritious and better protected against unpredictable weather. Cassava is no exception. Both farmers and consumers throughout the world can reap the benefits of varieties that are healthier, heartier and more abundant.

Cassava provides sustenance for over 800 million people. A perennial woody shrub native to Latin America, cassava is primarily grown as an annual crop in the humid tropics. Studies indicate it is the only staple crop that stands to benefit from climate change. As more land is rendered unusable due to changing temperature and rainfall patterns, cassava will likely gain ground as a staple around the globe.

We spoke with Chiedozie Egesi of NextGen Cassava Breeding Project, who is at the forefront of new innovations to enhance this already resilient and hearty staple crop. Read our interview with him to learn how and why cassava is a major staple crop of the developing world and what its future holds. (This interview has been formatted for brevity and clarity.)

Chiedozie Egesi – Project Leader at NextGen Cassava Breeding Project
Chiedozie Egesi, leader of the NextGen Cassava Breeding Project, tells us how he and his team are developing better cassava plants to resist challenging growing conditions, be more productive and deliver more nutrition.

Tell me about your role at NextGen Cassava. What type of research do you lead?

Our main objective is to empower African cassava farmers through innovative, sustainable cassava breeding. We have begun the process of modernizing cassava breeding institutions in Africa and use cutting-edge tools for efficient delivery of improved varieties of cassava.

My role includes project coordination, charting the course we take and ensuring that our partners are supported to deliver on the project mandate. We specialize in cassava breeding implementation—cutting-edge research technologies that make for more efficient processes and demand-led breeding.

Why is cassava a staple crop in South America, Africa, and other developing countries?

Cassava is a major calorie source for over 800 million people. It has high productivity in marginal environments, making it an invaluable asset for food security—it survives where other crops fail. It also has naturally high resilience to climatic changes. Finally, it is produced mainly by smallholders [farmers with less than 2 hectares of land] – mostly women – with simple technologies, allowing it to be easily grown across multiple countries and environments.

What challenges have cassava farmers faced in recent years?

Cassava producers face several main challenges these days. First, many pests and diseases have constrained production for cassava growers. Part of this is actually because of cassava’s long growth cycle—its long duration in the field increases its exposure to pests and viruses. Also, cassava is perishable, which leads to limited flexibility in handling. Lastly, poorly linked value chains in Africa cause frequent boom-and-bust cycles of high and low productivity. The markets have not been well developed to make for sustainable agribusiness.

How have plant science innovations helped cassava farmers?

A recent example is the timely delivery of new, “best-bet” varieties to cassava farmers. Genomic selection is an integral technology that has enabled us to get these more resilient, more productive and more nutritious varieties. We have employed innovative “citizen science” approaches to enable participatory selection of improved varieties. In addition, new technologies have helped us rapidly screen large breeding populations. Others include techniques to improve flowering in cassava, an essential step for hybridization through pollination. Application of a combination of hormones has enabled us to make cross combinations that were not very easily done due to the poor flowering of some cassava varieties.

Which plant science innovations does NextGen Cassava utilize in its work with smallholder farmers?

We predicted the performance of new varieties based on the genetic information of their parents using modeling systems. This allowed us to reduce the generational cycle time for cassava from about 10 years to five. Better varieties can now get to farmers faster, and we are still working on further improving this. We are designing research that maps preferences and links to social differences such as gender, age, education, region, poverty and food security levels.

How will climate change continue to impact cassava and smallholder farmers?

Cassava is one of the most climate-smart crops in the tropics and has the capacity to withstand changes in the atmosphere, which it can use to its advantage for more productivity. As climate change continues to be a challenge for smallholder growers in Africa, cassava farmers stand a better chance to make more profitable agribusiness due to the robustness of the crop. 

How will supporting plant science innovations help communities that depend on cassava?

Support for plant science innovations is needed to help communities that depend on cassava in Africa. New technologies will transform cassava production and deliver the best varieties for maximum impact on growers and their families.

Kenya Approves Disease-Resistant Biotech Cassava

In June 2021, the Kenya National Biosafety Authority approved the environmental release of genetically modified cassava, which is resistant to cassava brown streak disease. The disease-resistant cassava was developed under the Virus Resistant Cassava for Africa Plus project, a collaborative program between Kenya Agricultural and Livestock Research Organization, National Crops Resources Research Institute of Uganda and Donald Danforth Plant Science Center. Learn more about this breakthrough from the Cornell Alliance for Science and ISAAA.

Repairing the Root of the Problem

Despite the ability to turn cassava into an endless number of palatable dishes, the tuber has two major issues affecting the people who rely on it the most. First, cassava faces the threat of brown streak disease, limiting available food and second, the crop has a natural toxin that can cause severe physical and mental damage in the populations who need it most. For the millions it feeds, this important crop must be usable. That’s where plant biotechnology and gene editing come in. This video from the American Seed Trade Association and University of California at Berkeley shows the research being done to improve this staple crop for the millions who depend on it.

Save and Grow Cassava: A Guide to Sustainable Production Intensification
The Food and Agriculture Organization (FAO) of the United Nations has published a booklet about the production of cassava. It notes that cassava was first cultivated 9,000 years ago on the southern edge of the Brazilian Amazon, where it is still grown. Today, around 300 million tons of cassava are produced globally, with Nigeria as the world’s largest producer. Around 90 percent of harvested roots are destined for human consumption, while about 10 percent are semi-processed on-farm as animal feed. Read the entire 100-page PDF on the FAO website.

African Scientists Improve Cassava to Help Feed the World
2019 article in the journal Nature explains how researchers at the International Institute of Tropical Agriculture in Nigeria are using both traditional breeding and genetic modification to improve the starchy staple crop. In Africa, where consumption is highest, cassava plants bear smaller yields than their cousins in Asia and South America. But African varieties tend to be more tolerant of blights, such as the deadly cassava mosaic disease now spreading across Asia.

Breeding Better Crops, From Maize to Cassava
In this video from the Gates Foundation, United States Department of Agriculture (USDA) Agriculture Research Service (ARS) and Cornell University, plant geneticist Ed Buckler explains that cassava has not been bred as effectively as other crops – such as maize – and there is tremendous potential including disease and insect resistance, by taking new, modern breeding tools and applying them to cassava.

Developing GM Super Cassava For Improved Health and Food Security: Future Challenges in Africa
The potential for GM cassava also includes biofortification. According to a study in the open access journal Agriculture & Food Security, more than 800 million people suffer from micronutrient malnutrition in developing countries with Africa accounting for almost 50 percent of the children who are clinically or sub-clinically deficient in vitamin A, particularly under five years of age. The study found that an overwhelming majority of scientists agree that GM biofortified cassava will benefit the health of millions in Africa and that GM cassava conferred with disease and pest resistance will increase cassava production as it is currently plagued by cassava mosaic diseases (CMD).

CROPLIFE ASIA ECHOES FAO CALL TO TRANSFORM OUR FOOD SYSTEMS

Highlights need for agricultural innovation in addressing Asia’s growing food security crisis / Helping reach region’s hungry, undernourished

Singapore, 13 July 2021 – With the release of the United Nations (UN) 2021 State of Food Security & Nutrition in the World (SOFI) report, CropLife Asia highlighted the need for the region’s food value chain stakeholders to work together in transforming our food systems to better enable food security, improved nutrition, and affordable healthy diets for all.

The challenge of achieving the UN’s Sustainable Development Goal (SDG) 2 of ‘zero hunger’ globally by 2030 has grown even more complicated with the broad impact of the COVID-19 pandemic. In this latest UN report, it is estimated that the number of people affected by hunger worldwide in 2020 was between 720 and 811 million people. This is a marked increase of over 100 million more people than in 2019. The prevalence of undernourishment (PoU) has also climbed up to around 9.9 percent in 2020 compared to 8.4 percent the previous year. This new report also confirms a sadly familiar refrain for Asia: our region is failing to deliver food security for far too many – particularly among the more vulnerable parts of society. Asia continues to be home to the greatest number of undernourished people with 418 million suffering from hunger in 2020.

“The challenge of feeding Asia and the world requires us to explore all possible solutions. This can only be achieved through greater collaboration with others, as multi-stakeholder approaches are crucial for transformation of our food systems.” said Dr. Siang Hee Tan, Executive Director, CropLife Asia. “The plant science industry champions innovation in both crop protection and plant biotech, as well as precision and digital agriculture solutions to benefit both people and the planet.”

“The innovative technologies of the plant science industry have a key role to play, but it is only one part of the solution,” Dr. Tan added. “Ensuring that an ample supply of affordable and nutritious food reaches those who need it most is a shared responsibility. Farmers’ access to innovation is an increasingly crucial component to combatting food insecurity in Asia and around the world.”

Global crop losses due to pests and disease are a major contributor to global food loss and waste. These losses would be twice as high without the use of crop protection products. Crop losses can be further reduced through more effective crop protection stewardship practices. Without innovations such as crop protection products and plant biotechnology, global pre-harvest crop losses could double(1). Meanwhile, biotech crops are developed with improved traits such as increased yield, better resistance to pests and/or improved nutrition, among others. These traits are crucial tools that enable farmers to produce more food using fewer resources to feed our growing world.

SUDANESE YOUTH LEADER ON CLIMATE CHANGE AND AGRICULTURE

By: CropLife International

Nisreen Elsaim

Nisreen Elsaim

There is no planet B. Our earth’s environment must be both preserved and restored in order to secure a sustainable future for generations to come. The United Nations’ 13th Sustainable Development Goal states that we must take urgent action to combat climate change and its impacts. Younger generations of advocates are taking notice of this imminent concern.

To meet these goals, all industries and sectors of the world must make climate change — and the existential threat it poses — a top priority. The agricultural sector is far from an exception. But it will be a solution.

We spoke with Nisreen Elsaim, chair of the United Nations (UN) Youth Advisory Group on Climate Change and chair of the Sudan Youth Organization on Climate Change, about the effects of climate change, especially in developing countries, and the role agriculture and plant science can play in combatting it. This interview had been formatted and adapted from its original recording for brevity and clarity.

Can you tell us about the U.N. Youth Advisory Group on Climate Change and what you do?

Nisreen Elsaim: The first ever Youth Climate Summit happened in 2019 in New York, right before the Climate Action Summit. Between the two summits, there was some youth involvement with the secretary-general to expand the influence of young people and better recognize their efforts in addressing climate change. One of the recommendations was to establish an advisory board for the secretary-general with young people taking action on climate. This led to the creation of the Youth Advisory Group.

This group is very diverse both in graphical representation and background. For example, Paloma Costa from Brazil represents Latin America and she’s a lawyer. Archana Soreng is from India; she’s in research and comes from an indigenous community. Vlad Kaim is from Moldova; he represents Eastern Europe and he’s the economist of the group. And I represent Africa. My background is in physics, and I have a master’s degree in renewable energy. I’m currently focusing on climate policies.

Our mandate is very simple: we advise the secretary-general on things that young people think should happen within the UN system. We play the role of a bridge between the secretary-general and young people.

What makes developing countries the most vulnerable to climate change? And how have the impacts of climate change been felt in Sudan?

NE: I recorded a video that covers just this. We know that climate change is real and that it is human made. A third of Sudan is covered by desert and desertification is a growing problem. The country has gone through a decades-long civil war and conflict over natural resources. This has put biodiversity, fertile land, food and water security in greater danger and made the country very vulnerable in the face of climate change. Floods destroy buildings, fields and people’s livelihoods, and they will get worse as climate change gets worse.

The country cannot compensate farmers who’ve lost whole harvests to floods. There are some insurance companies, but not everyone has access to them. Many farmers don’t have other options so they stick to agriculture. It’s a risky investment, especially in the flood season, which we know already they cannot change. Some farmers skip the flood seasons and try to intensively do agriculture in different seasons, but others take the risk.

There are many misconceptions about climate change in agriculture. What do you think is the most common myth that you encounter around the two topics?

NE: Well, I think there is more misunderstanding, or misjudging, about the situation. Not only in agriculture, but also with livestock. A lot of people think that eating meat is increasing a lot of emissions in the environment. And it’s true, but in certain climate or weather conditions, it’s different. For example, a cow in Sudan does not produce the same amount of methane as a cow in Poland or in Germany. Why? Because the climate situation in Sudan is very dry and hot. And we all know that methane is actually an organic result of fermentation.

Fermentation requires the presence of water. It needs specific conditions which don’t really exist in a dry, hot country like Sudan, but they do in humid, wet and cold countries like Poland, the Netherlands or Germany. So, it’s not the same impact. It’s not the same effect. And definitely, it’s not the same emission of methane gas.

What tools can help farmers best address the challenges presented by climate change?

NE: Desertification is a huge issue in Sudan and it’s moving very fast, covering big areas. Many tools can help address desertification. One example is center pivot irrigation, where you actually irrigate the crops in circles which helps farmers use water efficiently.

What are the concerns associated with misinformation around climate change and agriculture and the way that our food is produced?

NE: First, farmers who have a misunderstanding of the problem will implement the wrong solution, which perpetuates the problem.

A lot of consumers care about the origin or impact of their food. So, economically it will impact the farmer, especially in countries where farmers sell directly to consumers. If the consumers stop buying from the farmers, the farmers’ livelihoods are at serious stake.

In addition, general misunderstandings create a very negative atmosphere. In a country like Sudan, this will impact the policies, legislation and laws. Policies could be passed without any scientific basis.

What role do you think agriculture can play in helping communities adapt to climate change?

NE: In order for agriculture to help the community adapt to climate change, we must first help the agriculture industry adapt to climate change.

If agriculture becomes somehow immune to — or at least less impacted by — climate change, then it directly helps and supports communities through better food security, economic prosperity and so on. It will secure farmers’ income. It will secure food security, which is very important. And if we ensure a very good agricultural cycle, then we can even have other activities to increase the income and diversity of food. Building the resilience of communities through green jobs like agriculture is key.

What major milestones in the youth movement for climate change are you looking forward to?

NE: One of the things we are looking forward to is the Youth COP that will be held in Milan in September. It will be a very good milestone for the youth movement of climate change and climate diplomacy.

Climate change poses an existential threat to all countries, sectors, industries and businesses on earth — no matter how big or small. The only way to properly tackle this challenge is to work together. The agricultural sector offers much in the way of climate change solutions. The sooner we can dispel myths surrounding agriculture and climate change, the sooner we can more effectively fight back against it.

HOW PLANT SCIENCE IS SUPPORTING THE PLANET’S POLLINATORS

By: CropLife International

Download the full infographic here.

The relationship between pollinators and agriculture is one of the most vital on the planet. Many of the crops we rely on to feed our growing populations would be impossible to produce without pollinators, making them crucial to our food systems.

As such, agricultural techniques that support pollinators and their habitats can play a critical role in ensuring the sustainability of our food production. Pollinators are facing a number of challenges, from habitat loss, to the impacts of climate change, disease and other pests.

Plant science innovations and other techniques are helping provide the answers to many of these challenges. Integrated Pest Management (IPM) takes a holistic view of crop protection that limits environmental impact and utilizes agronomic practices such as plant spacing or mulching. Innovations like, GM varieties of plants offer intrinsic pest resistance, limiting the need for control methods, while herbicide resistant crops allow for less tilling of soil, which protects the natural biodiversity of our topsoil.

By looking at some of the world’s most important crop and pollinator relationships we can explore how plant science gives farmers a variety of tools to protect their crops at the same time as supporting pollination. But first, who are the world’s pollinators and exactly how important are they to our food systems?

Farmers are acutely aware of their reliance on pollinators for the success of their crops. They also rely on plant science innovations to protect those crops from pests and ensure the highest possible yields. Luckily, both these vital parts of the agricultural process can support each other as shown by the pollinator partnerships below.

The squash bee is one of many vital species that helps pollinate the summer squash in the U.S. This crop was facing a significant threat from the zucchini yellow mosaic virus (ZYMV). Plant science again came to the rescue with a ZYMV-resistant variety of the summer squash.

ZYMV is spread by Aphid populations so before the introduction of the GM squash, farmers were tackling the virus by limiting ‘green bridges’. These connecting sections of local wild vegetation were being used by aphids to move between crops. Removal of these natural spaces, however, had the consequence of limiting squash bee ranges and habitats. The GM summer squash reduced the need for this control method, allowing squash bees to enjoy more wild spaces and to move freely between and pollinate many different fields of crops.

Cocoa is facing significant challenges. Increased problems related to pests are having impacts on yield, with 30-40% of global production affected. Climate change and habitat erosion are affecting chocolate midge populations. As one of the only species small enough to successfully pollinate cocoa, any reduction in chocolate midge populations leads to a significant pollinator gap developing.

Using IPM to reduce impacts of attempts to control pests can help support pollinator populations. Alternative control methods such as use of natural predators and sex pheromones to limit mirid populations can tackle pests without affecting pollinator partnerships.

Similarly, to its work in protecting the papaya and the summer squash, plant science may hold the long-term solution. Work is currently underway on creating new pest-resistant GM varieties that could make a big difference to cocoa production.

Strawberries can be pollinated by a diverse range of pollinators. In fact, strawberry fields that have a variety of pollinators show increased size, boosting yields. With this in mind, pest control methods must be as carefully implemented as possible to avoid disrupting these relationships.

Integrated Pest Management can have positive impacts for many crops, but for fruit with complex needs like strawberries it is particularly effective. Innovations include the deployment of natural predators for pests like mites and using tractor-mounted vacuums for managing species with no useable natural predators. Light traps have also been installed to counter butterfly pest populations without impacting on insect pollinators.

A key tool for farmers is the development of innovative biological products that are derived from fungi, bacteria and plants. Able to be integrated seamlessly with traditional crop protection methods, biologicals can increase crop yields and quality. They are able to target pest species such as aphids and whitefly, while having negligible impact on pollinators such as honeybees and wasps.

The hawkmoth is a key pollinator of papaya. Back in the late 1990s, Hawaii’s papaya crops were being devastated by the papaya ringspot virus (PRSV) and the island was facing the potential end of all papaya production. PRSV is transmitted to papaya plants via insects feeding on its leaves. This meant farmers were faced with the difficult task of tackling an insect-transmitted virus on a crop that relied upon insect pollination.

Traditional attempts to prevent the spread of PRSV could have had negative long-term impacts on the native hawkmoth population. Thankfully, plant science had the solution. Identifying the gene that would make papaya plants resistant to PRSV, plant scientists created new varieties of papaya called Rainbow and SunUp. These new types of papaya, combined with pest control methods that support pollinators, had positive knock-on effects for hawkmoths. This allows the pollinator relationship to flourish and ensures the ongoing health of Hawaii’s papaya farms.

The symbiotic relationship between farmers, their crops and the world’s pollinator species, is one of the most powerful in the world. Giving farmers access to the full agricultural toolkit allows them the flexibility to combat pests, while limiting impacts on biodiversity and supporting the world’s pollinators.

HOW PLANT SCIENCE DEFEATED THE PAPAYA RINGSPOT VIRUS

By: CropLife International

Papayas are grown and enjoyed in many parts of the world — from Taiwan to Cuba, and from South Africa to Greece. They’re eaten on-the-go as a quick refreshing snack, and incorporated into dishes like Cambodian bok l’hong or Javanese buntil. Papayas are especially important in Hawaii, where they are grown both on big commercial farms and in families’ personal gardens. They have been a staple local fruit and principal export ever since they were first introduced to the islands over 100 years ago. But if it weren’t for the efforts of Dr. Dennis Gonsalves and his diverse team of plant scientists from the public and private sectors to save the fruit, the papaya industry may have been lost. For decades, papayas in Hawaii were plagued by the papaya ringspot virus, or PRSV, named for its iconic symptom of rings appearing on the papaya’s skin. The virus, transmitted to papaya plants via insects feeding on the leaves, spreads and kills quickly.

Jonathan Valdez is a professional dietitian nutritionist from Hawaii, whose family witnessed the effects of PRSV on papaya firsthand. Listen to his own words on the importance of papayas in Hawaii, the devastation PRSV had on farmers, and how plant science came to the rescue.

After years of spread throughout the Hawaiian Islands, the production of papayas was for a time safely relegated to a specific region in the Puna District on the Big Island. However, despite efforts to prevent its spread, by 1992 PRSV had penetrated the Puna District and its effects were instantly noticeable. By 1997, statewide papaya production fell from 55.8 million pounds to 35.7 million pounds. After failed efforts and solutions to contain the virus and stop the spread, papayas in Hawaii were facing an existential crisis. But there was one solution still in the works that showed major potential — biotechnology.

“Basically, we were following the pioneering work of Roger Beachy’s lab on transgenic tobacco and tomato for resistance to tobacco mosaic virus,” said Dr. Gonsalves. “Our team consisted of Richard Manshardt, a horticulturist at University of Hawaii; Maureen Fitch, a graduate student of Richard Manshardt focusing on papaya tissue culture and transformation; and Jerry Slightom, a molecular biologist at Upjohn Company.”

Dr. Gonsalves and his team had to identify the specific gene in the virus that, if inserted in a papaya’s genetic makeup, would make them resistant to PRSV. Once they identified that gene, they used it to create a variety of papaya seeds with DNA including said trait. Using new technology, the team inserted an isolated protein gene of the virus into the cells of papaya seeds, which then grew into resistant papaya plants.

“We made timely research progress because our team had expertise in molecular biology, virology, horticulture and tissue culture, and we were focused on the specific goal of developing a transgenic papaya to help farmers,” said Dr. Gonsalves.

The researchers and farmers planted GM papaya seeds — which produced a protein that made it resistant to PRSV — along with a set of non-GM papaya seeds in a trial. The trials were a huge success, as the GM papayas were found to be resistant to PRSV while the non-GM papayas were wiped out.

The next step was to gain regulatory approvals — not just for the export of the papayas themselves, but also the seeds for farmers throughout the world to grow. Dr. Gonsalves and his team created two varieties of the GM papaya, called SunUp papaya and Rainbow papaya.

“SunUp and Rainbow papaya were potential candidates to rescue the papaya industry from the devastation of PRSV — but transgenic papaya needed regulatory approval,” said Dr. Gonsalves. “Since our team did not have company backing and we were committed to helping the farmers, we took it upon ourselves to file for deregulation. We petitioned USDA-APHIS, the FDA and the EPA for the deregulation of GM papaya line 55-1, the transgenic parent of SunUp and Rainbow.”

“When we got approval in 1998, six years after PRSV invaded the papaya in Puna, a celebration was held in Hilo and initial seeds were released free to growers,” Dr. Gonsalves continued.

After a much-deserved celebration, Dr. Gonsalves still worked with international regulators to ensure that GM papaya can be exported throughout the world — including key markets like Japan, Canada and China.

Today, a vast majority of the papayas grown in Hawaii are GM, grown with resistance to the virus.

“The transgenic papaya saved the Hawaiian papaya industry, and growers began planting transgenic papaya and reclaiming PRSV-infect papaya fields,” said Dr. Gonsalves. “Rainbow became — and still is —the dominant cultivar grown in Hawaii, always present in the supermarkets and farmer’s markets alike.”

Modern genetic engineering can accomplish in just a few years what traditional plant trait breeding used to take decades to do. Thanks to the efforts of plant scientists and genetic biologists, a popular and globally enjoyed fruit was saved from possible extinction — to say nothing of the impact these innovations had on local communities and the livelihoods of farmers and papaya producers across the food value chain. This is just one example of how biotechnology works behind the scenes to improve lives.

“I believe that the transgenic papaya enabled the Hawaiian people to continue to have ready access to a fruit that has been traditionally eaten in Hawaii,” Dr. Gonsalves continued. “The transgenic papaya is nutritious, delicious and it is arguably the least expensive fruit on the supermarket shelves in Hawaii.”

“I have not seen a PRSV infected papaya tree in several years — the result of herd immunity,” said Dr. Gonsalves. “Our papaya project shows that a bunch of public sector scientists can produce a GMO product and help to get it to farmers by going the extra mile. It is my hope that more public sector GMO projects will be done to help farmers and people.”

The innovations spearheaded by Dr. Gonsalves and his team were vital to protecting this important crop and promoting local economies in Hawaii. Plant science plays a key role in protecting crops, mitigating the effects of climate change and improving nutrition globally. Watch the video below to hear dietitian Jonathan Valdez’s professional insights on GMOs and the importance of looking to science and evidence to help form your opinions.

UNDER THREAT – HOW PLANT SCIENCE IS TACKLING FIVE OF THE WORLD’S MOST DESTRUCTIVE THREATS TO CROPS

By: CropLife International

Across the globe, farmers are protecting our global food supply from the world’s most destructive pests. Check out these infographics below to see how plant science is aiding farmers in their fight and providing sustainable approaches to pest management.

DESERT LOCUST

The Desert Locust is a serious threat to the food security of East Africa, and crop protection products play a key role in preventing hunger and starvation in the region.

FALL ARMYWORM

Fall Armyworm is native to the tropical and subtropical regions of the Americas and has been found in Eastern and Central North America, South America, and most recently, detected in Africa and Asia. Because its mature moths can fly almost 500km (300 miles), it could quickly migrate from Africa into southern Europe.”

Farmers in China are looking to plant science innovations to help fight the fall armyworm, like FAW–resistant biotech corn, and other IPM technologies in their agricultural toolkit.

FUSARIUM TR4

Already threatening farmer livelihoods across Asia and Africa, the TR4 fusarium fungus is now hitting South American banana plantations and has no known fungicidal treatment, but there is hope thanks to the advancement of genetic modification technologies.

Given the rapid spread and devastation of Fusarium TR4, genetic engineering tools offer an effective, safe, and viable way to develop resistant varieties. Genetic engineering, which facilitates the transfer of useful genes across species, has been shown to offer numerous advantages to circumvent the natural bottlenecks to breeding bananas for its improvement.

The example of the Gros Michel and the Cavendish banana varieties highlight the significant threat posed by a pest that has no control method and the importance of an effective and accessible agricultural toolkit, including genetic modification technologies.

BLACK POD

West Africa is a powerhouse of cocoa production, but one of the world’s most beloved crops is facing immense pressure from pests, and farmers are working harder than ever to keep the supply of cocoa going, on top of facing climate related stressors.

West Africa is also suffering under the Cacao Swollen Shoot Virus (CSSV) which can kill trees in just three years, and has no cure. It is estimated that since 1946 more than 200 million cocoa trees have been cut down due to CSSV.

Ensuring that West Africa farmers have access to the full agricultural toolkit will enable them to effectively meet the challenge of pest management on their cocoa farms. Without flexible and accessible options, the world’s supply of one of its more treasured crops could be under serious threat.

SPEARGRASS

Integrated pest management is critical in dealing with some of the toughest of pests, like speargrass, that would otherwise run rampant destroying millions of hectares of crops. It is critical for farmers to not only have access to, but be educated on the variety of plant science technologies that are available to them.

WOMEN WINNERS OF THE WORLD FOOD PRIZE

By: CropLife International

The World Food Prize (WFP) is awarded for a specific, exceptionally significant, individual achievement that advances human development with a demonstrable increase in the quantity, quality, availability of, or access to food through creative interventions at any point within the full scope of the food system. All of the women recognized below have been bestowed this prestigious award for their contributions to feeding our planet.

Dr. Maria Andrade and Dr. Jan Low, Developed the biofortified orange-fleshed sweet potato at the CGIAR International Potato Center.

Dr. Maria Andrade and Dr. Jan Low were both awarded the 2016 World Food Prize for the development and application of biofortification, breeding vitamins and nutrients into crops. Their efforts have dramatically reduced ‘hidden’ hunger for millions around the world.

Born in 1958 in the Cape Verde Islands, Andrade secured a place at the University of Arizona, studying Agronomy with support from an African-American Institute scholarship. She received a masters in Plant Genetics before earning a Ph.D. in Plant Breeding from North Carolina state University in 1994. Andrade orientated her efforts towards improving food security in Africa and developed a profound interest in biofortified crops after conducting her Ph.D. research on the sweet potato.

Jan Low was born in 1995 in Colorado before attending Pomona College in California. She undertook a study abroad programme in Kenya which inspired her to build a career in Africa where she became committed to combating Vitamin A deficiency and improving nutrition.

To counter the tragic effects of Vitamin A deficiency, both Andrade and Low conducted a multi-year research project to develop disease-resistant, drought-tolerant and high-yielding varieties of orange-fleshed sweet potato. This sweet potato variant is widely grown in the variable conditions of Sub-Saharan Africa.

Collaborating as a team with Robert Mwanga, Andrade and Low demonstrated that Vitamin A enriched crops provide immense benefits to human health and childhood development. After gaining financial backing from funders such as the Bill & Melinda Gates Foundation, the team began breeding programs of orange-fleshed sweet potato varieties across Africa.

Andrade and Low’s efforts have forged a new alliance among agronomists, plant breeders,  and public health experts, altering the way the international community functions. Even more importantly, their development of a biofortified sweet potato has dramatically reduced levels of micronutrient deficiencies, hunger and disease for millions in Sub-Saharan Africa.

Dr. Mary-Dell Chilton, Developed science of modern plant biotechnology

Joint winner of the 2013 World Food Prize, Dr Mary-Dell Chilton was a pioneer in the plant biotechnology space and her research has greatly improved sustainability and global food security.

Chilton was born in Indianapolis in 1939. Chilton’s studies focused on the chemical basis of biological specificity and she soon became intrigued by the possibilities of genetics and plant biotechnology.

Chilton’s research at Washington University provided evidence that plant genomes could be manipulated in a far more sophisticated way than was possible using traditional plant breeding. In the next phase of her career at Syngenta Biotechnology, Chilton set up one of the world’s first agricultural biotechnology programs. The program utilised Chilton’s ground-breaking research in areas such as disease and insect resistance.

Upon receiving the World Food Prize in 2013, Chilton had already spent three decades overseeing and improving the implementation of the new technology she helped develop. The work of Chilton, and the other receivers of the 2013 World Food Prize, led to the creation of a new term, ’agricultural biotechnology’. Ag biotech allowed for engineered crops that improved yields, helped combat disease and displayed increased tolerance to a variety of environmental conditions.

The work of Chilton has improved the yields and incomes of farmers in over 30 countries. Today, corn, soyabeans, canola and cotton are biotech crops which are grown on a large scale and are an essential part of agricultural production. In 2018, up to 17 million farmers planted biotech crops, with 95% of those coming from developing countries. As a result of Chilton’s discoveries, millions of smallholder farmers and their families have seen increased incomes and greater food security.

Jo Luck, Building Heifer International into one of the world’s foremost grassroots organizations, leading the charge to end hunger and poverty around the globe

Jo Luck was the joint-winner of the 2010 World Food Prize for her valiant efforts in fighting hunger and providing income-producing animals to over 12 million families through her role at Heifer International.

Born in 1941 in Arkansas, Luck studied at Hendrix College and became a teacher before being hired as the first director of Arkansas Advocates for Children and Families. Following experience as Director of Parks and Tourism for Arkansas, Jo luck became director of global services at Heifer International. Here she travelled across the world, visiting remote sites and getting first-hand experience of the organization’s work in helping lift people out of poverty.

In 1992, Luck became CEO of Heifer and expanded the organisation’s efforts to combat hunger by teaching communities how to become self-sustaining. Financial support for the organisation grew exponentially throughout her leadership and Heifer soon enabled many to access nutritious food, with more than 34 million families helped as of 2021.

One of Luck’s innovative approaches as CEO included increasing the public’s knowledge of how life choices made in wealthier countries affect those living in deprived communities. She issued a call to action to supporters which collectively funded over 30 varieties of livestock and animals from water buffaloes to bees in addition to trees and seeds. This initiative grew capacity within malnourished communities and created a sustainable food supply to support livelihoods.

Luck is now one of the most inspirational speakers in the world on the issue of hunger and food security. She transformed Heifer International into a top-class organization fighting hunger across the planet and laying the groundwork for more sustainable food supplies.

Catherine Bertini, Transformed the World Food Programme

The winner of the 2003 World Food Prize was Catherine Bertini. As its leader, Bertini transformed the World Food Programme from a development assistance program into the world’s largest and most effective humanitarian relief organisation. Although plant science is important in increasing the quantity and quality of food, increasing accessibility to this food is equally critical.

Bertini was born in 1950 in New York where she attended school and university, earning a degree in political science from the State University of New York at Albany in 1971. Bertini worked in philanthropic and government affairs in Chicago before becoming the assistant Secretary at the US Department of Agriculture in 1989. Her experience overseeing 13 food assistance programmes prepared her to head the United Nations World Food Programme (WFP).

As executive director of the WFP, Bertini spent much of her time on the ground, observing the processes of food distribution. She pursued fundamental reforms, enhancing the programme’s effectiveness and turning the WFP into the most responsive humanitarian relief organization in the world. In 2003, the year after Bertini left her post, the WFP shipped 1,000 metric tons of food every hour of every day.

Bertini was also a strong believer in women taking an active role in channelling food aid as a means of ensuring equitable distribution. By the end of her term, over 60% of the WFP’s assistance was delivered through women. Bertini also prioritized the fight against childhood malnutrition during her tenure at the WFP. Under her leadership, 3.3 million North Korean children and millions of the country’s citizens were saved from severe malnutrition.

Bertini has undoubtedly transformed the lives of millions of people in some of the world’s most deprived areas. She was and still is a champion in the fight against malnutrition and her work transformed the WFP into an efficient, responsive and highly effective organisation.

Dr. Evangelina Villegas, Developing high quality protein maize (QPM)

Winner of the 2000 World Food Prize – the first woman to be recognized by this award – Dr. Evangelina Villegas’ years of research and work were focused on improving the nutritional content and productivity of maize. Thanks to the plant science innovations of Dr. Villegas, there was a dramatic improvement in food security and enhanced health that continues to reduce poverty and hunger.

Born in Mexico City, Dr. Villegas started her career in 1950 as a chemist and researcher at Mexico’s National Institute of Nutrition before continuing her education in the US in the 1960s, earning a Ph.D. in cereal chemistry from North Dakota State University.

Her most impactful work would be conducted at the International Maize and Wheat Improvement Center (CIMMYT), which she joined in 1967. At CIMMYT, during the early 70s, her and Dr. Surinder K. Vasal began collaborating in Mexico on improving the protein quality of maize. This work would follow that of World Food Prize founder Dr. Norman Borlaug, who 30 years earlier had revolutionized wheat production in the country.

Maize is a staple food across much of the world, with 90 million hectares of it currently grown by farmers across Mexico, Central America, Sub-Saharan Africa and Asia. Following rice and wheat, maize’s position as the third most important cereal crop in the world meant that improving its nutritional content could have far-reaching impacts for the hundreds of millions of people who rely upon it.

The maize germplasm developed through Dr. Villegas’s research has added billions to the economies of developing countries and improved the diets of millions of previously undernourished people. This is one of the most significant contributions to improving food security in human history.

The work of these laureates is critical as they continue to be on the front lines of combatting global hunger. The UN World Food Programme in 2020 received the Nobel Peace Prize for their lifesaving food assistance to millions across the globe.
