Screening cycle for deadly MLN virus set to begin in Kenya during April 2018

The maize lethal necrosis (MLN) artificial inoculation screening site in Naivasha, Kenya will begin its phenotyping (screening/ indexing) cycle of 2018 at the begining of January 2018 and in four other intervals. Interested organizations from both the private and public sectors are invited to send maize germplasm for screening.

In 2013, the International Maize and Wheat Improvement Center (CIMMYT) and the Kenya Agricultural & Livestock Research Organization (KALRO) jointly established the MLN screening facility at the KALRO Naivasha research station in Kenya’s Rift Valley with support from the Bill & Melinda Gates Foundation and the Syngenta Foundation for Sustainable Agriculture.

MLN was first discovered in Kenya in 2011 and quickly spread to other parts of eastern Africa; the disease causes premature plant death and unfilled, poorly formed maize cobs, and can lead to up to 100 percent yield loss in farmers’ fields.

CIMMYT and partners are dedicated to stopping the spread of this deadly maize disease by effectively managing the risk of MLN on maize production through screening and identifying MLN-resistant germplasm. The MLN screening facility supports countries in sub-Saharan Africa to screen maize germplasm (for hybrid, inbred and open pollinated varieties) against MLN in a quarantined environment.

This is the largest dedicated MLN screening facility in East Africa. Since its inception in 2013, the facility has evaluated more than 120,000 accessions (more than 210,000 rows of maize) from more than 15 multinational and national seed companies and national research programs.

Partners can now plan for annual MLN Phenotyping (screening/ indexing) during 2018 with the schedule listed below. The improved and streamlined approach for MLN phenotyping should enable our partners to accelerate breeding programs to improve resistance for Maize MLN for sub-Saharan Africa.

 

2018  annual phenotyping (screening/ indexing) schedule:

When the seeds are available  Planting Period – Planned MLN Screening / Indexing
December Second Week of January MLN Indexing
March Second week of April MLN Screening
June Second Week of July MLN Indexing
August Second Week of September MLN Screening
October Second week of November MLN Indexing

 

More information about the disease and resources for farmers can be found on CIMMYT’s MLN portal.

 

Please note that it can take up to six weeks to process imports and clear shipments.

Ag women speak out for International Day of Girls and Women in Science

Girls and women are underrepresented in the fields of science, technology, engineering and mathematics (STEM). The likelihood of female students graduating with a degree in a science-related field is much lower than for male students, according to a U.N. study conducted in 14 countries. In an effort to improve their representation, a U.N. resolution established February 11 as the International Day of Women and Girls in Science.

To celebrate the occasion this year, CIMMYT asked women involved in agricultural science to share their views on what they would like to see change.

There are two inspiring women in science, who have made significant contributions to the world. The first woman is Wangari Maathai and the second woman is Marie Curie. Maathai was the first woman in East and Central Africa to earn a doctoral degree, the first to become a professor at the University of Nairobi. She made a significant contribution to environmental/forest conservation, women’s rights and peace.  In 1977, Maathai founded the Green Belt Movement (GBM), an organization focused on the planting of trees, environmental conservation and women’s rights. The GBM has planted over 51 million trees in Kenya. In 2004, she became the first African woman to win the Nobel Peace Prize.

French-Polish scientist Curie’s work led to the discovery of radium and polonium in 1898, setting the stage for nuclear medicine, which allows internal imaging of tumors. Curie is the first person and only woman to win a Nobel Prize twice, including the 1903 physics prize jointly with her husband Pierre Curie and Henri Becquerel, and the 1911 chemistry prize. She was also the first woman to win the Nobel Prize.

The key factor that will encourage women and young girls to get involved in science is to be paired up with already practicing women scientists through mentorship programs so that they see firsthand what it is like to be a female scientist, and what it takes to become one. Starting a mentorship early in life – from the primary school level – will inspire young female students to take more interest in science classes and contemplate a career in science.

Women’s contributions to science are vast and immeasurable. Heroes like Jane Goodall and Marie Curie, are some of the world’s most famous scientists who also happen to be women. One of my own personal role models from the past is Antoinette Brown Blackwell, who isn’t usually remembered as a scientist, but her efforts to dismantle the barriers to women in science and other research and intellectual fields is a major source of inspiration to me. Today, I am inspired every day by the young scientists in the CGIAR, both women and men, who continue to challenge all forms of gender disparity and are making huge contributions to our body of knowledge.

Women have long contributed innovations to various scientific fields, but their efforts are not always acknowledged, remembered or encouraged as readily as their male counterparts. Women of all ages have been fighting an uphill battle to become equals in the scientific community. Progress is being made but young women still face too many barriers to enter STEM fields and there are still too many hurdles to clear once they enter the workforce. The statistics speak for themselves and must not be ignored. The world needs these women scientists and we need to do all we can to nurture them and encourage a new generation of young women to enter into STEM fields. We must encourage and excite young women about studying STEM subjects, especially in developing countries. We can do this by profiling more female role models and by ensuring that new and established scientists get their fair share of airtime in publications and on conference panels. Sadly, I still see far too many male-only panels at STEM conferences. We all have a role to play in creating a work environment that provides opportunities for everyone to succeed, regardless of gender. Together, we must continue to support and elevate woman scientists within our workplaces and throughout the CGIAR system. I pledge to do my part to support and champion this movement.

In my opinion, getting more girls and women involved in science will create more innovation, creativity and competitiveness. Women look at issues and research in a different light than men and are often more effective in communication. We must change the current perception of science as a negative, especially in agriculture. It is my hope that women will be able to talk about the benefits of innovation and technology in a manner that makes it easier to understand and acceptable to the public.

I would like to see more STEM programs in schools as well as in after-school programs and camps to introduce girls to science at an early age. Introduction at an early age is critical to furthering their passion and interest. By the time they are teenagers, they are more influenced by their peers and it is often too late to gain their interest.

Additionally, there are many opportunities for parents to provide toys that expose girls to math, chemistry and physics at an early age. Lego sets and many science kits have lines focused solely on girls and provide an important way for girls to grow confident in their capabilities. Several web-based STEM-themed games and apps have been released to encourage girls’ interests.

We need more young female scientists to serve as mentors to girls through various media, including social media outreach. It is hard to find programs or social media activities that highlight young female scientists to inspire girls. We must make a concerted effort to change this and empower the current and future generation of scientists!

Women and girls have made significant contributions in various science disciplines, especially in agriculture, irrespective of their social status. We know women are the major workforce in agriculture worldwide, but sometimes they are marginalized due to limited land rights. When this is the case, they have less control over resources. Women’s contributions to agriculture are significant, across the sector, starting with research and development, and including the deployment of scalable technology leading to the capacity to make an impact on humanity.

It is essential to bring women working in agriculture into the mainstream and to empower them with direct access to knowledge of improved agricultural technologies. The female presence in scientific fields has been largely disproportional compared to male; however, the trend is slowly changing, as more and more women are entering these fields.

Equality in recognition of their contributions and equal rights in ownership of the resources might work as a strong motivator for women and girls to get more involved in science.  Introducing women and girls to scientific fields and encouraging them to follow their hearts and minds irrespective of social issues that influence career choices could also help overcome the negative perceptions that girls develop at a young age that science is a hard subject, leading them to avoid it. Friendly environments in high school and the university level, inviting females to participate and get over a fear of science, would encourage those with talent and a genuine interest to develop their interest.

Encouraging women to participate in training and workshops by motivating young girls to explore and challenge typically male-dominated fields could also help bolster the number of women in the field. As well as providing more financial assistance in the form of fellowships so that they become financially independent.

Parents are primary mentors, and therefore right from the beginning if there is support, women and girls can accomplish much more. The value of mentorship outside the home is also irreplaceable. In the past, we have seen the majority of successful women credit their success to their mentors for helping them reach career goals.

Many girls begin making a significant contribution to science from a very early age. As they grow older, a sizeable portion of them will work in various research organizations, contributing to science in different fields. Women often also play a big supporting role in the successes of men working for science. Thus, women, directly and indirectly, contribute to scientific advancement.

In my opinion, enabling environments in family, society and in communities, promoting knowledge gathering, support for education and career development will encourage more women and girls to get involved in science. For example, in some countries, certain people have the mindset that women and girls must still be confined to household activities, an unfair bias limiting access to opportunities and exposure to science.

Deadly strain of wheat stem rust disease surfaces in Europe

As reported today in Communications Biology, an international team of researchers led by the John Innes Centre, U.K., found that 80 percent of U.K. wheat varieties are susceptible to the deadly stem rust strain. The group also confirmed for the first time in many decades that the stem rust fungus was growing on barberry bush, the pathogen’s alternate host, in the UK.

“This signals the rising threat of stem rust disease for wheat and barley production in Europe,” said Dave Hodson, senior scientist at the International Maize and Wheat Improvement Center (CIMMYT) and co-author on the study.

A scourge of wheat since biblical times, stem rust caused major losses to North American wheat crops in the early 20th century. Stem rust disease was controlled for decades through the use of resistant wheat varieties bred in the 1950s by scientist Norman Borlaug and his colleagues. Widespread adoption of those varieties sparked the Green Revolution of the 1960s and 70s.

In 1999 a new, highly-virulent strain of the stem rust fungus emerged in eastern Africa. Spores of that strain and variants have spread rapidly and are threatening or overcoming the genetic resistance of many currently sown wheat varieties. Scientists worldwide joined forces in the early 2000s to develop new, resistant varieties and to monitor and control outbreaks of stem rust and yellow rust, as part of collaborations such as the Borlaug Global Rust Initiative led by Cornell University.

The Communications Biology study shows that 2013 U.K. stem rust strain is related to TKTTF, a fungal race first detected in Turkey that spread across the Middle East and recently into Europe. It was the dominant race in the 2013 stem rust outbreak in Germany and infected 10,000 hectares of wheat in Ethiopia’s breadbasket the same year.

Because disease organisms mutate quickly to overcome crop resistance controlled by single genes, researchers are rushing to identify new resistance genes and to incorporate multiple genes into high-yielding varieties, according to Ravi Singh, CIMMYT wheat scientist who participated in the reported study.

“The greatest hope for achieving durable resistance to rust diseases is to make wheat’s resistance genetically complex, combining several genes and resistance mechanisms,” Singh explained.

Barberry, which serves as a spawning ground for the stem rust fungus, was largely eradicated from the U.K. and U.S. last century, greatly reducing the spread and genetic diversification of rust disease races. Now barberry is being grown again in the U.K. over the last decade, according to Diane G.O. Saunders, John Innes Centre scientist and co-author of the study.

“The late Nobel laureate Norman Borlaug said that the greatest ally of the pathogen is our short memory,” Saunders stated. “We recommend continued, intensive resistance breeding. We would also welcome work with conservationists of endangered, barberry-dependent insect species to ensure that planting of common barberry occurs away from arable land, thus safeguarding European cereals from a large-scale re-emergence of wheat stem rust.”

“Bazooka” maize makes a bang in Uganda

Unprecedented droughts have hit Uganda’s farmers hard in recent years, affecting household income and food security by drastically cutting maize yields, a staple crop in the country. In 2016, at least 1.3 million people in Uganda faced hunger and urgently needed food aid after a dry spell decimated harvests, leaving some with less than one meal per day. When MLN, a maize disease with the ability to cause extreme or complete crop loss in maize, arrived in Uganda in 2013, farmers needed a variety that could cope.

Enter, “bazooka,” a new maize variety that is giving hope to Ugandan farmers facing climate change-related drought and MLN.

Developed by Uganda’s National Crops Research Resources Institute (NaCRRI) and National Agricultural Research Organization (NARO) using traditional breeding methods and materials from the CGIAR Research Program on Maize (MAIZE) and the International Maize and Wheat Improvement Center (CIMMYT), bazooka maize has natural resistance to drought and MLN. Produced and distributed by the Naseco seed company, bazooka is gaining immense popularity in Uganda.

300 million people depend on maize as their main food source in sub-Saharan Africa, where many smallholder farmers do not have access to irrigation systems, and extended drought can be a death sentence for their crops. Now, with new drought tolerant varieties such as bazooka, they can expect better harvests.

New technical guide to help farmers protect against fall armyworm

32577231314_a7b9506122_kNairobi, Kenya (CIMMYT) – A new comprehensive integrated pest management (IPM)-based technical guide produced by international experts will help scientists, extension agents and farmers to tackle the fall armyworm (Spodoptera frugiperda), which has rapidly spread across the African continent in the last two years, decimating maize crops in its path.

Fall Armyworm in Africa: A Guide for Integrated Pest Management,” jointly produced by Feed the Future, the United States Agency for International Development (USAID), the International Maize and Wheat Improvement Center (CIMMYT) and the CGIAR Research Program on Maize (MAIZE), provides tips on fall armyworm identification as well as technologies and practices for effective control.

Native to North America, the fall armyworm has recently emerged as a major threat in Africa, where it has been identified in over 30 countries since it was first confirmed on the continent in January 2016. The pest can potentially feed on 80 different crop species but has a preference for maize, which poses a significant threat to the food security, income and livelihoods of over 300 million African smallholder farm families that consume maize as a staple crop.

“The potential impact of the fall armyworm as a major food security and economic risk for African nations cannot be overstated,” said Martin Kropff, director general at CIMMYT.

If proper control measures are not implemented, the fall armyworm could cause extensive maize yield losses of up to $6.2 billion per year in just 12 countries in Africa where its presence has been confirmed, according to the Centre for Agriculture and Biosciences International (CABI).

“The fall armyworm poses an enormous and wide-scale risk to the livelihoods of several million African smallholders, and requires urgent deployment of an IPM strategy and quick response from all stakeholders,” said B.M. Prasanna, director of MAIZE and the Global Maize Program at CIMMYT. “The Fall Armyworm Integrated Pest Management Guide provides comprehensive details on the best management practices to help smallholder farmers effectively and safely control the pest while simultaneously protecting people, animals and the environment.”

New Publications: Goat grass gives wheat breeders an edge

A new commentary published today in the leading science journal Nature Plants highlights the importance of an ancient grass species for wheat breeding. The commentary was sparked by the recent publication of a reference genome from Aegilops tauschii, also called goat grass.

Bread wheat was created some 10,000 years ago by a natural cross of more simple, primitive wheats with a sub-species of goat grass. As such, goat grass genes constitute a major component of the very large wheat genome. The sequencing of goat grass DNA opens the way for wheat breeders to apply a number of advanced approaches to improve the speed and precision of wheat breeding for important traits that may be found in the goat grass segment of the wheat genome.

The International Maize and Wheat Improvement Center (CIMMYT) has produced many wheat x grass crosses, recreating the original, natural cross but using other goat grass species and thus greatly expanding wheat’s diversity. Wheat lines derived from those crosses have since been used in breeding programs worldwide and have helped farmers to boost yields by up to 20 percent. Goat grass is known for being highly adaptable and disease tolerant, so the crosses endow wheat with similar qualities. Varieties from these crosses make up over 30 percent of international seed stores.

Researchers expect that the sequencing of this grass species’ DNA will facilitate advanced approaches such as “speed breeding” – a technique that uses controlled variables to achieve up to seven rounds of wheat crops in one year. This will help allow wheat breeding to keep up with the rising global demand for the crop and to address the challenges of new, virulent diseases and more extreme weather.

CIMMYT research publications sow seeds in academic world

Based on publication records, CIMMYT scientists produce a lot more than just improved maize and wheat varieties, as important as that work has been for farmers, partners, and consumers.

In 2017, CIMMYT researchers contributed to nearly 300 peer-reviewed journal articles, many published in high-impact journals including Nature and Science. The articles emerged from partnerships with a broad range of international universities and research institutes and have been cited frequently by peers in recent years.

“CIMMYT is the world’s largest distributor of publicly-available maize and wheat ‘germplasm,’ which includes breeding lines and other genetic resources in the form of seed,” said Marianne Bänziger, CIMMYT deputy director general for research and partnerships. “But the center’s researchers also publish high-quality, cutting-edge science articles, not to mention mentoring and training several hundred students and professionals mostly from national research systems every year and interacting with thousands of farmers.”

Multiple CIMMYT authors led by José Crossa, CIMMYT biometrician and distinguished scientist, published two papers in Heredity on genomic selection in maize and wheat that have been among those most often cited for that journal since 2013, having been mentioned in other papers 124 times.

Ravi Singh and Julio Huerta, CIMMYT wheat scientists, were recognized in 2017 among the top one percent of researchers for the frequency of citation of their articles by other science authors.

Among the many reports to which they contributed, Huerta and Singh were participants and co-authors in a study published in the eminent journal Science in 2009 and since cited by other researchers 441 times. The study described the molecular basis of a “wonder” gene that, in tandem with other resistance genes, has helped protect wheat from three deadly fungal diseases for more than 50 years, providing farmers benefits in excess of $5 billion in harvests saved, according to a CIMMYT report on the findings.

The two scientists share authorship on at least a half-dozen other articles on wheat disease breeding and genetics that have been cited over 100 times.

“These examples show that CIMMYT research substantially contributes to global science, in addition to the impact achieved in farmers’ fields,” said Bänziger. “It all builds on high-value partnerships with hundreds of researchers and professionals worldwide.”

Are you a wizard or a prophet?

Charles Mann’s The Wizard and the Prophet released today seeks to reconcile two worldviews spurred by agronomist Norman Borlaug and ecologist William Vogt, to help us better understand how we can feed 10 billion people by 2050; without destroying our planet in the process.

Borlaug, the “wizard” of the book, launched his vision from a small parcel of “badly damaged land” near Mexico City that would become the International Maize and Wheat Improvement Center (CIMMYT). He was a key figure in developing high-yielding wheat varieties that saved millions from starvation in the 1960s, launching a global Green Revolution and becoming an emblem for “techno-optimism,” or the view that science and technology will meet humanity’s growing demands.

Vogt’s 1948 book “The Road to Survival” became the blueprint for today’s modern environmental movement, prophesizing that unless humankind drastically reduces consumption, its growing numbers and appetite will overwhelm the planet’s resources. His novels and speeches inspired conservationists from Rachel Carson to Paul Ehrlich, and defined our concept of “environment” as an entity that deserves respect and protection.

Mann uses the views of Borlaug and Vogt as endpoints on a “wizard-prophet” spectrum to illustrate different approaches experts are taking to solve four great, complex challenges of our time: food, water, energy and climate change.

But who is right? We, humans, are the only species on Earth that have been able to bend nature to our will. For thousands of years we burned forests to kill insects and encourage the growth of useful species, then later turned the planet into our “personal petri dish,” as Mann puts it, with the rise of agriculture and creation of crops like maize, which allowed Mesoamerican civilizations to grow and flourish. Today, violence and poverty are at an all-time low due to the wizardly-successes of Borlaug and others

However, Mann cautions past successes are no guarantee of the future. Vogt’s Malthusian predictions didn’t come to pass, but Borlaug’s wizardry also had unintended social and environmental consequences. Fertilizer runoff, over-extraction of groundwater and the burning of fossil fuels are creating an increasingly inhospitable planet and arguably pushing us closer to Vogt’s envisioned planetary limits than ever before.

Both Borlaug and Vogt identified as environmentalists trying to solve the same monumental challenge of having too many people to feed but not enough resources. Their ideological heirs are also working to solve equally challenging problems but are bitterly opposed, in large part because the argument is less about facts and more about values.

Prophets see humans as living in a finite world with constrained limits imposed by the environment, while wizards believe human ingenuity gives us an endless array of tools to manage the environment for our needs.

Mann doesn’t take either side, but rather offers solutions proposed by both prophets and wizards. He cites efforts to change the way photosynthesis works in rice at the International Rice Research Institute, but also initiatives like the domestication of wild perennial plants at the Land Institute. Both prophets and wizards have multiple, on-going efforts to meet all four challenges that Mann covers in the book. He says that it’s possible individual efforts won’t work, but the odds of all efforts failing are equally small.

Most importantly, there are many individuals and organizations today that are attempting to embrace both ideologies. CIMMYT, an organization that was founded by the original wizard, now incorporates sustainable agriculture practices into its work globally, with an emphasis on social inclusion.

The Wizard and the Prophet’s in-depth mix of biographical, historical, philosophical and scientific detail allows us to confront our wizard/prophet bias, and leaves one with a greater sense of respect for those with differing views on how we should shape our world in the 21st century.

With increasing global demand for wheat and increasing constraints (high temperatures, diseases) to wheat’s productivity, wheat breeders are looking for new methodologies to make breeding more efficient. A new study looks at refinements of genomic prediction models to help achieve this.

The authors write that genomic selection is becoming a standard approach to achieving genetic progress in plants, as it gets around the need to field-test the offspring at every cycle, but that the models commonly used in plant breeding are based on datasets of only a few hundred genotyped individual plants.

This study used pedigree and genomic data from nearly 59,000 wheat lines evaluated in different environments, as well as genomic and pedigree information in a model that incorporated genotype X environment interactions to predict the performance of wheat lines in Mexican and South Asian environments.

They found that models using markers (and pedigree) had higher prediction accuracies than models using only phenotypic data. Models that included genomic x environment had higher prediction accuracies than models that do not include interaction.

In response to Ethiopia’s worst drought in 50 years and the country’s critical shortage of maize and wheat seed for sowing in 2016, Ethiopian organizations, seed producers, and the International Maize and Wheat Improvement Center (CIMMYT) partnered to deliver to farmers over 3,400 tons of high quality seed that was sown on more than 100,300 hectares.

“We went three years without rain,” says farmer Usman Kadir, whose 1.5-hectare homestead in Wanjo Bebele village, Halaba Special Woreda, supports a household of 11 persons. “We were able to eat thanks to emergency food programs.” In 2017, Kadir used emergency maize seed to sow half a hectare and harvested 3 tons, getting his farm back on its feet. “If more new improved varieties come, we want to work with you and expand our farming operation.”

Funded by the U.S. Agency for International Development (USAID) and Office of Foreign Disaster Assistance (OFDA) of the U.S. Ethiopia mission, seed relief complemented international and national food aid, helping farm families to quickly grow crops after several seasons of erratic or failed rains in Ethiopia and the catastrophic 2015-16 El Niño droughts. At that time, more than 10 million people struggled to find food, as eastern Ethiopia faced crop losses from 50 to 90 percent of expected yields.

“This effort helped rescue the food security and livelihoods of more than 271,000 rural households and 1.6 million individuals in Ethiopia’s Amhara, Oromia, Tigray, and SNNP regions, and strengthened seed systems to address future climate, disease, and pest crises,” said Bekele Abeyo, CIMMYT wheat scientist who led the seed relief initiative.

Wheat and maize: Mainstays of food security

Agriculture provides 42 percent of Ethiopia’s GDP, 77 percent of employment, and 84 percent of exports. Subsistence, smallholder farmers predominate, making their living from less than two hectares of land. Wheat and maize are the most important crops for food security; they are also at the center of Ethiopia’s increasingly vibrant agricultural output markets and have been the focus in recent years of public investment to raise national production.

Maize and wheat production in Ethiopia depends on rainfall, making the unpredictable weather patterns caused by climate change exceptionally detrimental here. Various studies predict an average 30 percent reduction in farm incomes due to climate change impacts, including greater extremes in temperatures and rainfall (floods, droughts) and the emergence of new pest and disease strains. Research shows that reduced precipitation is already holding back wheat yields.

To address this, experts identified maize and wheat varieties suitable for drought-affected areas and highly resistant to prevalent crop diseases. Of the maize varieties, some 10 percent were quality protein maize, which carries enhanced levels of key amino acids for protein synthesis in humans.

“This effort also provided training for district and zonal development agents in crop protection, agronomy, drought mitigation practices, and seed systems,” said Abeyo. “Finally, five women seed producer associations received wheat seed threshers and a large union of farmer seed producer cooperatives received a maize sheller through the initiative. This equipment will greatly expedite their operations and contribute to the expanded and more reliable access of farmers to affordable, quality seed in the future.”

Partners and contributors

Emergency relief seed was sourced through diverse CIMMYT partnerships, including producers in the USAID-funded “Drought Tolerant Maize for Seed Scaling Project” (DTMASS) and “Wheat Seed Scaling Initiative.” Stakeholders included the Ministry of Agriculture and Natural Resources (MoANR), the Bureau of Agriculture and Natural Resources (BoANR), public and private seed companies/enterprises, farmer cooperative unions, federal and regional research institutes, and non-government organizations working in target areas. With funding from the Bill & Melinda Gates Foundation, Ethiopia’s Agricultural Transformation Agency (ATA) helped deliver seed to drought-affected districts and jointly organized training and workshops.

DHAKA, Bangladesh – On December 10 2017, The International Maize and Wheat Improvement Center (CIMMYT) joined the South Asian Association for Regional Cooperation (SAARC) in celebrating the 33rd SAARC Charter Day – the annual festivities commemorating the formation of SAARC. The day was celebrated through a special agricultural exhibition and regional seminar on agricultural mechanization in the Bangladesh Agricultural Research Centre (BARC) campus, Dhaka.

With the theme “International Year of Agricultural Mechanization”, the event aimed to educate the attendees on improved farm machine and technologies, and promote agricultural mechanization for sustainable intensification of agriculture to achieve greater food and nutrition security in South Asia.

CIMMYT exhibited its conservation agricultural (CA) techniques and machines that have been developed in collaboration with public and private sector partners. The exhibition stall was visited by government officials (including two ministers in Bangladesh), NGOs and private sector organization, as well as people off the street.

The Minister for Planning A. H. M. Mustafa Kamal inaugurated the event and later visited CIMMYT’s exhibition stall.

Women are the foundation for change in rural Ethiopia

The idea that “Educating women/girls is nothing but a loss,” used to be a common sentiment amongst members of rural Ethiopian communities where the Nutritious Maize for Ethiopia (NuME) project works. Now one is more likely to hear “Women are the foundation for change.”

The International Maize and Wheat Improvement Center (CIMMYT)-led NuME project is reducing food insecurity in Ethiopia by increasing the country’s capacity to feed itself. The project is improving household food and nutritional security, especially for young children and women, through shifting gender norms and the adoption of Quality Protein Maize (QPM).

QPM refers to a type of maize biofortified with two essential amino acids through traditional breeding to improve the inadequacy of protein quality of the conventional maize grown widely by farmers. Consumption of QPM instead of conventional maize leads to increase in the rate of growth in infants and young children with mild to moderate undernutrition from populations in which maize is the major staple food.

According to the World Bank, women contribute 40-60 percent of the labor in agricultural production in Ethiopia and play an important role in income generation, as well as unpaid household tasks. However, many women face severely restricted access to resources and services and lack control over income, greatly hindering their participation in and benefit from new innovations.

Few programs have specifically considered gender relations when implementing new initiatives in communities, however, when NuME found lower participation of women in the community-based promotion and dissemination of QPM, adapted community conversations were launched in two selected project woredas, or districts – Shebedino and Meskan – for a nine-month pilot in an attempt to raise women’s role in the project.

Community conversation (CC) is a facilitated approach based on the principle that communities have the capacity to identify their societal, economic and political challenges; set priorities; mobilize human, physical and financial resources; plan for action and address their challenges sustainably. It focuses on people’s strengths, resources and how they relate to challenges or problems communities face.

The people benefiting from a CC-driven project set priorities and create a plan of action to mobilize resources to address their challenges sustainably. This helps communities develop a sense of ownership, use local resources and take responsibility to bring about sustainable changes.

Because this approach involves the entire community, it also includes traditionally marginalized groups like women and youth.

When NuME first started community conversations, seating was very rigid due to cultural and religious traditions, but as the sessions continue paving the way for more community awareness on issues around gender norms and stereotypes, the seating has become much more mixed.

A facilitator from Shebedino woreda said, “Participants can’t wait for the bi-monthly conversations and they never want to miss them. These exchanges have helped men and women to get together and discuss their concerns, which was not a common practice before.”

“Women have begun raising their voices during community conversation meetings, while they used to be too shy and afraid to speak and very much reserved about sharing their ideas in public,” a female participant from Meskan woreda reported.

Community conversation participants have started changing the traditional gender stereotypes.

Through debate and the sharing of opinions, and more active participation from women, community conversations have educated participants on gender inequality, its prevalence and harm and have allowed men and women community members to exchange ideas about nutrition more effectively.

The NuME project will continue into 2019. Read more about how CIMMYT is working to equally boost the livelihoods of women, youth and men here.

The NuME Project is funded by Global Affairs Canada with major implementing partners the Ethiopian Ministry of Agriculture and Natural Resources (MoANR), the Ethiopian Institute of Agricultural Research (EIAR), the Ethiopian Public Health Institute (EPHI), the Sasakawa Africa Association (SAA)/Sasakawa Global 2000 (SG2000) and Farm Radio International (FRI).

Fifty years ago, economists and population experts predicted millions were about to die from famine.

India and other Asian countries were expected by scholars like Paul Ehrlich in The Population Bomb to be especially hard hit in the 1970s and 1980s, given the region’s high population growth rates.

South Asia braced for mass starvation as hunger and malnutrition spread while multiple droughts plagued India and neighboring countries – but it never happened.

Instead, rice and wheat yields more than doubled in Asia from the 1960s to 1990s, grain prices fell, people consumed nearly a third more calories and the poverty rate was cut in half – despite the population growing 60 percent.

Improved rice and wheat varieties combined with the expanded use of fertilizers, irrigation and supportive public policies for agriculture led to this dramatic growth in food production and human development that would become known as the Green Revolution.

Today, South Asia faces new, but equally daunting challenges. By 2050, the United Nations predicts the world’s population will grow by more than two billion people, 30 percent of which will be in South and Southeast Asia. These regions are also where the effects of climate change, like variable rainfall and extreme flooding, are most dire.

Wheat, maize and rice yields in South Asia could decrease by as much as 30 percent over this century unless farmers adopt innovations to mitigate rising temperatures and changing rainfall patterns.

Agricultural leaders from across South Asia recently gathered in Dhaka, Bangladesh to create a roadmap on how to best help farmers cope with climate change while meeting future food demand.

“South Asian agriculture needs to be transformed as it was during the Green Revolution,”  according to ML Jat, principal scientist at the International Maize and Wheat Improvement Center (CIMMYT) and co-author of a recent policy brief detailing the policy dialogue in Bangladesh. “Holistic management and more efficient use of resources to protect soil, water and air quality is necessary to improve both agricultural and human health.”

Public policies across the region currently subsidize agrochemicals, irrigation and unsustainable tilling, making it an uphill battle for many who promote sustainable intensification – a set of practices that adapt farming systems to climate change and sustainably manage land, soil, nutrient and water resources – as an alternative to these environmentally destructive practices.

Sustainable intensification advocates in South Asia have found that conservation agriculture – a sustainable management paradigm based on the principles of minimal soil disturbance, permanent soil cover and the use of crop rotation to simultaneously maintain and boost yields, increase profits and protect the environment – could be greatly expanded to benefit farmers across the region.

Conservation agriculture was first adopted in South Asia in the mid-1990s for no-till wheat farming and has since spread to cover more than 5 million hectares of farmland, mostly in India. Precision land levelers, machines equipped with laser-guided drag buckets to level fields so water flows evenly into soil — rather than running off or collecting in uneven land — were also adopted during this time, which significantly boosted conservation agriculture’s impact.

“When these technologies are combined with improved seed, like HD-2967, Munal, HDCSW 18, the benefits for farmers are even greater,” said Jat.

Despite this growth, conservation agriculture is practiced on just two percent of South Asia’s arable land, and very limited farmers end up adopting the complete set of sustainable intensification practices necessary to fully boost production while conserving the environment.

“While some practices like zero-till wheat have become very popular, growing rice in submerged fields remains a common practice which is one of the major obstacle in the adoption of full conservation agriculture in irrigated intensive rice-wheat systems of South Asia,” said Jat.

Policies that support farmers with few resources to take chances to experiment with conservation agriculture, such as guaranteeing a cash payout if crops fail or free access to zero-till machinery, can give people the incentive and protection they need to permanently shift the way they farm.

In addition to on-the-ground policy commitments, delegates in Bangladesh declared conservation agriculture and sustainable intensification should be at the heart of South Asia’s development agenda not only to improve national food security but to meet international obligations.

“If we don’t make South Asia’s farming sustainable, we will fail to meet international commitments on climate change, poverty and the environment, including the Sustainable Development Goals,” said Raj Paroda, Chairman of the Trust for Advancement of Agricultural Science (TAAS).

Delegates at the meeting called for a significant boost in funding towards conservation agriculture for sustainable intensification efforts, as well as the need to incorporate sustainable intensification practices in existing publicly-funded agricultural development initiatives.

Finally, the delegates created a platform where regional leaders, national agricultural research centers, donors and international research organizations can share knowledge, success stories, new technologies and expertise.

Success in mainstreaming CSISA-supported agricultural technologies

Since 2015, the Cereal Systems Initiative for South Asia (CSISA) has been working with Krishi Vigyan Kendras (KVKs) – agricultural extension centers created by the Indian Council for Agricultural Research – to generate evidence on best management practices for improving cropping system productivity in the Eastern Indo-Gangetic Plains.

Technologies and management practices essential to this research include early wheat sowing, zero tillage and the timely transplanting of rice. In response to clear evidence generated through the CSISA–KVK partnership, Bihar Agriculture University (BAU) announced in October 2017 that all KVKs in Bihar would promote early wheat sowing starting November 1. KVKs promoted this intervention by placing notices, which were designed by CSISA, on roadsides.

BAU also directed the KVKs to act as commercial paddy nurseries, supplying healthy rice seedlings in a timely manner to farmers.

Pairing these rice and wheat interventions is designed to optimize system productivity through the on-time rice transplanting of rice during Kharif (monsoon growing season), allowing for the timely seeding of zero-till wheat in Rabi (winter growing season).

Under the CSISA–KVK partnership, KVKs have supported early wheat sowing by introducing local farmers to the practice of sowing zero tillage wheat immediately after rice harvesting.

Evidence has shown that early sowing of wheat increases yields across Bihar and Eastern Uttar Pradesh. KVK scientists have begun to see the importance of breaking the tradition of sowing short duration varieties of wheat late in the season, which exposes the crops to higher temperatures and reduces yields.

Across the annual cropping cycle, monsoon variability threatens the rice phase and terminal heat threatens the wheat phase, with significant potential cumulative effects on system productivity. The combined interventions of early wheat sowing, zero tillage wheat and rice nurseries for timely planting help mitigate the effects of both variable monsoon and high temperatures during the grain-filling stage.

In 2016–17, data collected across seven KVKs (333 sites) indicated that yields declined systematically when wheat was planted after November 10. When planting was done on November 20 — yields declined by 4%, November 30 – 15%, December 10 – 30%, reaching a low when planting was done on December 20 of a 40% reduction in yield.

Rice yields are also reduced significantly if transplanting is delayed beyond July 20. The timing of rice cultivation, therefore, is important in facilitating early sowing in wheat without any yield penalty to rice.

KVKs are working to generate awareness of these important cropping system interventions, as well as others, deep in each district in which they work. CSISA supports their efforts and strives to mainstream sustainable intensification technologies and management practices within a variety of public- and private sector extension systems as capacity building are core to CSISA Phase III’s vision of success.
