EL BATAN, Mexico (CIMMYT) – In 2015, more than 100 countries pledged to reduce agricultural greenhouse gas (GHG) emissions during the Paris Agreement of the United Nations Framework Convention on Climate Change.

However, little technical information about how much mitigation is needed, versus how much we are capable of, is available.

A recent study which CIMMYT scientists and others participated in identifies this gap, stating that plausible agricultural development pathways that mitigate climate change only deliver 21-40% of what we need to limit warming in 2100 to 2 °C, an amount that is already predicted to cause large food security and other risks.

The authors of the study conclude saying that more transformative technical and policy options will be needed, such as methane inhibitors and finance for new practices if we are to limit our warming below 2°C.  In addition, they call for more comprehensive targets for the 2 °C limit to be developed including soil carbon and agriculture-related mitigation options.

They also say that excluding agricultural emissions from mitigation targets and plans will increase the cost of mitigation in other sectors, or reduce the feasibility of meeting the 2 °C limit.

KARNATAKA, India (CIMMYT) — Maize has emerged as a preferred choice for farmers in Karnataka, India, as it can be grown with less than a third amount of water needed for traditionally planted rice and has the potential to maintain farm profitability at par or better.

However, maize is prone to heat stress during its reproductive phase in spring, as temperatures peak in March and April. Because of this and the fact maize is a fully-irrigated crop, water availability is a challenge during this dry period.

Water-efficient and heat-tolerant maize hybrids are a great way for farmers in Karnataka to farm sustainably and maintain their livelihoods during this season. To put these varieties in the hands of farmers, the University of Agricultural Sciences (UAS) in Raichur, India joined the collaborative research project Heat Tolerant Maize for Asia (HTMA).

After three years, the first generation of heat-tolerant hybrids were developed, and suitable hybrids for Karnataka farmers were identified by UAS, Raichur. CIMMYT licenced the selected hybrids to the university for deployment and scale-out in 2015.

In order to get farmer input and feedback on these heat-tolerant hybrids, a field day was organized in Karnataka in collaboration with the Government of Karnataka’s Department of Agriculture.

The field day was attended by over 100 farmers, including both women and men, as well as participants from local seed companies, state agriculture department officials and officials from UAS, Raichur.

Director of Education and Former Vice-Chancellor of University of Agricultural Sciences (UAS), Raichur B.V. Patil inaugurated the event urging farmers to diversify rice-rice systems into more sustainable and profitable rice-maize systems, which is possible with the availability of heat-resilient maize hybrids. He elaborated that UAS, Raichur in collaboration with CIMMYT-Asia, Hyderabad have developed new heat-resilient maize hybrids with wide adaptability and are suitable for cultivation in this region.

Joint Director of Agriculture Chetana Patil also advised the farmers about other benefits of adopting rice-maize systems, such as- improved soil health, reducing weed seed back etc. apart from water saving and improved farm economy. V.N. Kulkarni, Vice President of research and development at   J.K. Agri-Genteics Ltd., Hyderabad  participated in the field day along with his maize research team and selected promising hybrids for deployment. S.N. Vasudevan, Head of the Agri-business incubation centre also visited the demonstration site along with his staff to assess the potential of the heat stress resilient maize hybrids under heat stress conditions. Other two seed companies, Mahindra Agri Solutions Ltd, Hyderabad and Mahyco Seeds Ltd, Jalna, Maharastra have expressed their interest in new heat stress resilient hybrids and wanted to take-up these hybrids for large scale testing followed by marketing in stress-prone ecologies.

Also attending the field day were Principal Investigator of HTMA Prakash Kuchanur;  S.N. Vasudevan, Head of the Agri-business incubation center at UAS, Raichur; and Mahindra Agri Solutions Ltd., Hyderabad and Mahyco Seeds Ltd., two seed companies who showed interest in purchasing the hybrids for large-scale testing and marketing in stress-prone ecologies.

Lead by CIMMYT and supported by USAID, the Heat Tolerant Maize for Asia project (HTMA) aims at improving income and food security of smallholder maize farmers living in climate-vulnerable regions through accelerated development and deployment of heat-resilient maize hybrids.

European Space Agency selects CIMMYT to pilot new remote sensing project

EL BATAN, Mexico (CIMMYT) – The International Maize and Wheat Improvement Center (CIMMYT) has been selected by the European Space Agency (ESA) to have access to the pilot version of the Sen2-Agri processing system and receive training on its use.

As an ESA “champion user,” CIMMYT will test the ESA prototype system in Bangladesh and Mexico. These two sites cover a wide range of farming systems, from the large wheat fields of the Yaqui Valley to a more diverse system in Bangladesh, where parcel sizes can be as small as 0.05 hectares and farmers grow two to three crops per year on a single field.

“The great unmanned aerial vehicle (UAV) expertise acquired by CIMMYT is very complementary to the full exploitation of the new satellite generation capabilities,” says Pierre Defourny, professor at the Université catholique de Louvain in Belgium who is leading the Sen2-Agri project. “CIMMYT’s two cases will generate products that will support our joint efforts for wheat blast monitoring in Bangladesh and improve data availability for GreenSat in Mexico.”

In the early days of remote sensing, limited availability of data was a major constraint for putting the data to good use. Basic processing of the coarse data was also time consuming and tedious.

Fortunately, this has greatly changed in recent years. Open and free satellite data, such as Landsat 8 and Sentinel 1 & 2, allow for almost weekly coverages at resolutions as fine as 10 meters. Thanks to this new speed and precision, users can now focus on applying the data, deriving information products even for small holder farmers in remote areas.

The Sentinel 2 satellites have a swath width of 290 km. Sentinel-2A is already operational, while Sentinel-2B will be launched in the spring of 2018. Together, they will be able to cover the Earth every 5 days.

For example, the CIMMYT-led STARS project in Bangladesh developed an irrigation scheduling app called PANI, which uses remotely sensed data to estimate crop water use. From this data the farmer receives a simple text message on their cell phone that gives recommendations as to whether a particular field needs to be irrigated or not.

Sen2-Agri is unique compared to other systems in that it simplifies and automates satellite data processing. The system allows for semi-automated generation of products, such as cropland detection, crop classification, normalized difference vegetation index (NDVI) and leaf area index (LAI) based on images taken periodically by satellites Sentinel-2 and Landsat 8.

A signing ceremony was held on 15 August, 2016 to seal the cooperation between ESA and CIMMYT. Bruno Gérard, Director of CIMMYT’s Sustainable Intensification Program, sees this agreement as a fundamental game changer for CIMMYT’s geo-spatial work.

“Sen2-Agri will give CIMMYT access to high spatial and temporal resolution quality imagery and related ‘know-how,’ which in turn will enable us to further develop partnership with top-notch institutions in the earth observation field,” says Gérard.

The benefits of the Sen2-Agri are likely to far extend beyond the Yaqui Valley and Bangladesh. After the pilot phase of this project, the high-resolution imagery gathered could be applied to other areas CIMMYT projects are implemented.

In combination with bio-physical and socio-economic data, this will allow CIMMYT and other organizations to improve monitoring and evaluation, better assess and understand changes and shocks in crop-based farming systems and improve technology targeting across farmer communities.

The Sen2-Agri test program is being coordinated by Urs Schulthess. Please feel free to contact him at u.schulthess@cgiar.org if you have questions about or suggestions for future applications of the system.

NAIROBI, Kenya (CIMMYT) – “The focus of the CIMMYT Global Maize Program includes elements that are key to many breeding programs in Africa. It has made important strides in sub-Saharan Africa.”

These words were delivered by Rita Mumm, a member of the International Maize and Wheat Improvement Center (CIMMYT) board of trustees and the coordinator of the Africa Plant Breeding Academy (AfPBA), which recently benefited from a wealth of knowledge shared by the CIMMYT Global Maize Program (GMP) team in Africa at the AfPBA training program held in June 2016 at the World Agroforestry Center.

The AfPBA is an initiative of the African Orphan Crop Consortium, a partnership of public and private organizations working together to sequence 101 crops of economic and nutritional importance to Africa. Students at AfPBA undergo a 13-month continuing education program delivered in three two-week sessions to learn about principles of plant breeding to enable use of advanced tools and technologies in breeding of crops relevant for Africa.

The CIMMYT team led by B.M Prasanna, director of CGIAR Research Program MAIZE and CIMMYT-GMP interacted with the trainees of the most recent session of the academy. The session was attended by 29 Ph.D. and master’s level scientists – including seven women – from 17 countries across Africa. The focus of the interactive session was to share knowledge on maize breeding work in sub-Saharan Africa and highlight the progress made in addressing various biotic and abiotic stresses affecting smallholders’ maize productivity in Africa.

The scientists learned about maize breeding work to develop improved maize varieties with farmer-preferred traits.  In particular, drought tolerance, nitrogen-use efficiency, nutritional enhancement, and disease resistance. In addition, presentation focused on the use of such modern technologies to increase efficiency and enhance genetic gains in tropical maize as molecular marker-assisted breeding and doubled haploid technology for maize improvement.

Collaborative efforts to strengthen the maize seed system for African farmers to access the improved new varieties was explained, as was the progress made with partners to increase farmer adoption as well as to replace the old varieties with the new climate resilient maize varieties.

“This is just one example of CIMMYT’s capacity development efforts that gives tremendous satisfaction. These breeding stories and highlights from Africa could have potential positive impact on the young scientists, as they are the key to further developing and deploying products that can make a difference in the livelihoods of the resource-poor smallholders in Africa,” said Prasanna.

The highlight of the training for many of the participants was the  tour to the Maize Lethal Necrosis (MLN) Screening Facility at Naivasha established jointly by CIMMYT and the Kenya Agricultural and Livestock Research Organisation (KALRO) to screen germplasm against MLN (under artificial inoculation), including germplasm from several private and public institutions. The participants received hands-on training to identify symptoms of MLN-causing viruses and how to score MLN disease severity by screening germplasm at the site. In addition, a demonstration was conducted on screening for MLN through artificial inoculation.

“Our global and regional mandate gives us the opportunity to support scientists across Africa to build their capacity in plant breeding work as well as in socioeconomics and sustainable intensification practices. Scienstists get the opportunity to learn, share their experiences and grow further. Through such  trainings, we  see improvements in  technology uptake and use in various countries and regions across Africa,” said Stephen Mugo, CIMMYT regional representative for Africa.

In addition to the CIMMYT team, instructors included Lago Hale from the University of New Hampshire, Bruce Walsh from the University of Arizona, Allen Van Deynze from the University of California–Davis, and Rita Mumm from the University of Illinois.

ISLAMABAD — Last year, the CIMMYT-Nepal office helped to introduce push row planters for small maize farmers in the Khyber Pakhtunkhwa Province (KP) in Pakistan. After a successful evaluation of these planters on more than 50 farmer fields in the districts of Nowshera, Mardan and Peshawar, CIMMYT collaborated this year with the Cereal Crops Research Institute (CCRI) and Petal Seed, a local seed company, for the local production of these planters.

In KP, maize is planted on 0.42 million hectares, and more than 60,000 farmers plant hybrid maize through traditional methods like broadcast and line sowing. These traditional methods are less precise – a lot of seed is wasted – and very labor intensive.

Push row planters have a vertical seed metering system that helps to place the maize seed at a proper plant-to-plant distance. They can also apply fertilizer and seed in one operation in tilled fields, thus saving labor costs, reducing planting time, and improving plant population and maize productivity.

The push row planters are manufactured and distributed locally on a cost sharing basis. Ameer Sani, a local manufacturer, assembles the planters in his workshop in Takht Bhai, in the district of Mardan. Farmers were satisfied with the performance of these locally manufactured planters, and on 21 July, 30 push row planters were distributed among smallholder maize farmers from the KP province during a farmer gathering in Mardan.

On this occasion, Iqbal Hussain, Director General of Agriculture Extension Services in KP, appreciated the efforts of USAID and CIMMYT, and advised the farmers that sharing the push row planters for maize planting would help to maximize benefits among the farming community in the village. Dr. Muhammad Imtiaz, Project Leader of the Agricultural Innovation Program for Pakistan (AIP), told the farmers that AIP would support the distribution of another 100 planters among KP farmers.

Raham Dil, a farmer from the village of Per Sadi in the district of Maran, not only used the planter on his own farm, but also offered it to 40 fellow farmers in his village and the surrounding areas, which resulted in more than 200 acres of maize planting.

A Chat With: IPNI Director Shamie Zingore — boosting smallholder agriculture in Africa

EL BATAN, Mexico (CIMMYT) – Effective partnerships involving research, public and private sector institutions are key to unlocking the potential of smallholder agriculture in sub-Saharan Africa, said Shamie Zingore, a director at the International Plant Nutrition Institute (IPNI), who oversees the region.

Cross-sector partnerships that deliver the results of agricultural research to smallholder farmers, who produce 80 percent of food consumed in the developing world, improve productivity and are essential to providing food security in Africa, said Zingore who will speak at a conference to mark the 50th anniversary of the International Maize and Wheat Improvement Center (CIMMYT) in September.

IPNI is a non-for-profit, science-based organization dedicated to the responsible management of plant nutrition.

Zingore said partnerships that bring together national governments, agricultural research institutes and industry  underpin his organizations’ work to support sustainable crop production intensification in the region.

IPNI’s cross-sector efforts to encourage fertilizer use within integrated soil fertility management (ISFM), which involves the use of locally adapted agricultural practices that can maximize the efficiency of nutrient and water use and improve agricultural productivity, shows the power of partnership combined with the development and dissemination of technologies that have increased yields and protected soil fertility, he said. The role of the private sector in addressing challenges that smallholder farmers face in accessing inputs at affordable prices and the knowledge for their appropriate use must be encouraged, he added.

Zingore will participate in a panel discussion during a session titled “Technical Innovations into Context to Achieve Greater Impact” at the CIMMYT 50th anniversary conference which will be held from Sept. 27 to Sept. 29 in Mexico City.

He shared some views on the future of agriculture in the following interview.

Q: What do you hope to contribute to the CIMMYT conference?

The theme of the conference is relevant and timely in the context of the increasingly urgent need to translate agricultural science into practice to support agricultural development and poverty alleviation in the developing world. I’m honored to participate at the conference to share knowledge and insights on the critical role of soil fertility management research in sustainable crop production intensification in sub-Saharan Africa — as well as the processes to achieve impact by adapting agronomic technologies to highly variable and complex conditions on smallholder farms. Effective partnerships between research, public and private sector institutions will be the key to unlock the potential of smallholder agriculture. Representing IPNI, as a fertilizer industry science-based research organization, I also hope to highlight the role of the private sector in addressing the challenges that smallholder farmers face in accessing inputs at affordable prices and the knowledge for their appropriate use.

Q: What is significant about CIMMYT? What role has CIMMYT played in your area of work?

CIMMYT has for many decades conducted innovative and transformational research to improve maize and wheat productivity through the plant breeding, agronomy, farming systems and conservation agriculture and socioeconomic programs. My institution has effectively collaborated with CIMMYT in several initiatives including the CGIAR  program on MAIZE and Taking Maize Agronomy to Scale (TAMASA) initiative that have supported wide-scale dissemination of site-specific nutrient management in both conventional and conservation agriculture maize production systems. CIMMYT has played a key role in building effective research and extension partnerships and capacity for delivering agronomic solutions to smallholder farmers in Sub-Saharan Africa.

Q: What are the key challenges the world faces into the future?

The overarching challenge is the question of how agricultural productivity can be increased to meet the food requirements by a rapidly increasing world population that will reach over 7 billion by 2050. Developing countries that are food insecure, including those in sub-Saharan Africa, will contribute most to the increasing population. Technological innovations will need to be increasingly robust to sustainably increase crop productivity and nutrient quality of food produced in the face of land degradation and climate change challenges.

Q: How does your area of specialization address these challenges?

Poor soil fertility, low fertilizer use and inappropriate fertilizer management practices are some of the key factors limiting crop productivity in sub-Saharan Africa. Yields have remained low despite advances made in developing high yielding crop varieties adapted to growing conditions in the region. Strong partnerships on developing ISFM are focusing on the development and dissemination of technologies that contribute not only to increased yields but also pay attention to maintenance of soil organic matter and soil fertility in the long-term. Our research results have shown that appropriate ISFM technologies enhance nutrient and water use efficiency, increasing crop productivity and resilience to moisture stress. We are addressing the issue of balanced nutrient management, with a focus on micronutrient fertilization, to increase productivity in vast agricultural soils that are deficient in micronutrients. Balanced fertilizer, focusing on the applying the right types of fertilizer at the right rate, time and place will be the basis of increasing yield in an economically viable manner and improving the nutrient contents of food produced by smallholder farmers.

TAMASA is a CIMMYT led project funded by the Bill & Melinda Gates Foundation.

NuME: a key actor in agricultural innovation systems in Ethiopia

ADDIS ABABA, Ethiopia (CIMMYT) — The Nutritious Maize for Ethiopia (NuME) project was selected as a key actor in agricultural and rural innovation in Ethiopia by the Capacity Development for Agricultural Innovation Systems project (CDAIS).

Funded by the European Commission and implemented by AGRINATURA and the Food and Agriculture Organization of the United Nations (FAO), CDAIS is a global partnership on capacity development for agricultural innovation systems (AIS), or collaborative arrangements that bring together several organizations working toward technological, managerial, organizational and institutional change in agriculture. CDAIS aims to make AIS more efficient and sustainable in meeting the demands of farmers, agri-business and consumers.

CDAIS identified NuME as one of the most successful projects in Ethiopia in its scoping study, largely based on its ability to demonstrate how multi-sectoral networks facilitate and speed-up the dissemination of quality protein maize (QPM) technologies and strengthen innovation. The QPM technology promoted is a biofortified type of maize with improved protein quality due to its enhanced amino acid profile that makes it more useful in human and animal nutrition.

NuME is founded on a network of key implementing partners from Ethiopian research institutions, national agricultural research and extension systems, international non-governmental organizations, universities and public and private seed companies and is implemented in 36 woredas (districts) of the four major maize producing and consuming regions of Ethiopia. Such multi-sectoral networking of actors has proved to be one of the most important factors that can bring  remarkably high rates of adoption of technologies bya large number of farmers in different countries.

All partners work together to ensure QPM spreads to as many farmers as possible. For example, Farm Radio International (FRI) collaborated with local radio stations, designing an appropriate multilingual participatory radio campaign on nutrition, protein and QPM benefits. Universities and Agricultural Technical and Vocational Education Training (ATVETs) produce agricultural experts with technical knowledge and skills in the field of QPM production and management. Meanwhile private sector seed companies produce and market QPM to meet the growing demand for the technology across the country.

The project has also brought the issue of QPM to the attention of policy makers and national agricultural development planners. As a result, Ethiopia’s Ministry of Agriculture and Natural Resources (MoANR) and the Agricultural Transformation Council have included QPM as a priority commodity in the national agricultural development plan. In 2014, MoANR set the target to increase the QPM production area to 200,000 ha within three years (2015-17), an area that is approximately 10 percent of the total land area devoted to maize production in the country.

Learn more about what makes NuME a success here.  

NuME is funded by Global Affairs Canada (GAC) and implemented by CIMMYT-Ethiopia in collaboration with various stakeholders from agriculture, nutrition and health sectors. The project is designed to contribute to the reduction of malnutrition, especially among women and young children, and to increase food security for resource-poor smallholder farmers in Ethiopia through the widespread adoption, production and utilization of QPM varieties and crop management practices that increase farm productivity.

RAICHUR, India (CIMMYT) — Two hybrids from the International Maize and Wheat Improvement Center (CIMMYT) developed under the Heat Tolerant Maize for Asia (HTMA) project were ranked first and third among over 100 hybrids during the 2015 All-India Coordinated Maize Program (AICMP) trials. The trials took place during the summer-rainy season (commonly known as the “Kharif” season) – the major maize growing season in South Asia – which covered about 70 percent of South Asia’s total maize area.

AICMP, managed by the Institute of Maize Research in New Delhi, is one of the largest maize variety testing networks in South Asia. New maize hybrids from both the public and private sector are evaluated in over 30 locations across India’s different ecologies.

The two hybrids RCRMH-1 and RCRMH-2 – were submitted by the University of Agriculture Sciences (UAS), Raichur, one of the key partners with CIMMYT in developing heat tolerant maize varieties in the region. The hybrids showed good performance by performing well across agro-ecologies, including stressed and un-stressed locations, competing well against both public and private sector varieties tested in the AICMP trials.

CIMMYT seeks to develop maize varieties that are tolerant to a range of stresses that South Asia experiences. For example, heat resilience is necessary in a region which experiences temperatures of over 400C in the spring season, right when the crop needs to reproduce. The summer-rainy season in South Asia brings monsoon rains. However, in drought years (such as year 2015) the temperature may rise close to 400C, and therefore maize crops face combined drought and heat stress. The selection strategy used by HTMA focuses on developing broad temperature resilience rather than tolerance to heat stress by exposing the hybrids across temperature regimes during selection process, which explains the success of the two hybrids in the AICMP trials. The performance of CIMMYT hybrids in these trials clearly indicate that the hybrids have wider adaptation to many stresses including areas with no stresses.

These two hybrids are among the first 18 hybrids licensed to CIMMYT partners for deployment and scale-out in stress-prone ecologies of South Asia.

University of Agricultural Sciences (UAS), Raichur, India is one of the collaborators in CIMMYT’s Heat Tolerant Maize for Asia (HTMA) project. Funded by the United States Agency for International Development (USAID) under the Feed the Future (FTF) initiative HTMA is a public-private alliance that targets resource-poor maize farming communities in South Asia who face weather extremes and climate change effects.

EL BATAN, Mexico (CIMMYT) — A new paper by scientists from the International Maize and Wheat Improvement Center (CIMMYT) highlight important risks to farmers’ yields in Pakistan due to climate change and call for current climate adaptation policies across South Asia to be revised in response.

Rice and wheat are the principal calorie sources for over a billion people in South Asia. Both of these crops are extremely sensitive to climate and agronomic management conditions under which they are grown.

Which is why climate change – projected to increase heat stress and variability across the region – is a huge threat to farmers growing these crops.

And while the influence of climatic conditions on crop growth have been widely studied, empirical evidence of the link between climate variability and yield risk in farmers’ fields is comparatively scarce.

Using data from 240 farm households, the paper “Climate variability and yield risk in South Asia’s rice–wheat systems: emerging evidence from Pakistan” responds to this gap and isolates the effects of agronomic management from climatic variability on rice and wheat yield risks in eight of Pakistan’s twelve agroecological zones. The authors’ results highlight important risks to farmers’ ability to obtain reliable yield levels for both crops, finding season-long and terminal heat stress have a negative effect on rice and wheat yields, with heat being particularly damaging to wheat.

The study also finds farmers have limited capacity to adapt to respond to climactic changes within a crop season, concluding that current climate change adaptation policies must be reviewed to increase resilience for Pakistan’s and South Asia’s cereal farmers, suggesting avenues for investment in improved crop research and development programs.

“Invisible women” hold key to food security – ex-WFP chief Catherine Bertini

EL BATAN, Mexico (CIMMYT) – In developing countries, 43 percent of income-earning farmworkers are women – a percentage that is even higher if unwaged farm work is included, according to the U.N. Food and Agriculture Organization (FAO).

Despite the large numbers of women working on farms, their voices are not heard by international development policymakers and funders, which handicaps global efforts to achieve food security, said the 2003 World Food Prize laureate and former head of the U.N. World Food Programme (WFP).

“When policymakers or grant-makers look at community needs, the dearth of women in leadership or spokesperson roles, prevents them from learning what is really required to best support the community,” Catherine Bertini wrote in a special issue of Daedalus, the journal of the American Academy of Arts and Sciences.

“Feedback comes from men, and it predictably centers on what men need,” she added, pointing out that the role of women in the fight for food security is vital not only because they are farmers, but also because they typically oversee nutrition and meal management in the household.

Women and men do not have the same access to agricultural inputs – to seeds and fertilizer, land and extension services, and FAO estimates that if they did, women’s agricultural production would increase up to 20 percent, said Bertini, who will speak at a conference on September 29 in Mexico City to mark the 50th anniversary of the International Maize and Wheat Improvement Center (CIMMYT).

Additionally, financial resources controlled by women are more likely to be spent on household needs in contrast to financial resources controlled by men, which are more likely to be used outside the household, Bertini said.

In her essay titled “Invisible Women,” Bertini, currently a professor at Syracuse University, cites a gender-specific mix-up with hoes as an example of how things can go terribly wrong when women farmers are not consulted about their needs.

During her tenure at WFP, Bertini visited a rural area in Angola, which was recovering from more than a quarter century of civil war. Farmers said they could not work the fields because they had no farm implements, although there were about a hundred hoes leaning against a nearby fence.

It turned out that the non-governmental organization (NGO) that ordered them was unaware that hoes in Angola were gender differentiated.

“The NGO had not talked to the women,” Bertini said. “In that region of Angola, women were the only people who tilled the fields, but they did not use the long-poled hoes. Women’s hoes, it turned out, had shorter wooden handles and shovel-like spades at the end.”

Women squat to use their hoes because they usually have a baby strapped to their back and it is less cumbersome and causes less stress on the back, unlike the men who stand.

“For me, this story became a metaphor for the importance of always speaking with the people who know what their needs are, and that those who do not specifically seek out women in order to understand their needs may waste their entire contribution to the good they seek to accomplish,” Bertini said.

“It also reminds me that women are generally not in community leadership roles and are too often politically invisible.”

She says for women to be seen and heard, and for society to benefit from their knowledge, changes must occur, including:

  • Educating girls
  • Starting research with women’s needs in mind
  • Enhancing women’s health support
  • Supporting breastfeeding
  • Improving women’s literacy
  • Creating agricultural extension programs that include women
  • Expanding micro-bank loans and insurance
  • Creating legal rights for women to own and inherit land
  • Considering societal gender roles in all development thinking

HYDERABAD, India (CIMMYT) – The International Maize and Wheat Improvement Center’s (CIMMYT) Director General Martin Kropff visited the CIMMYT office at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Hyderabad, India, on 26 August 2016, along with a delegation that included Mrs. Nynke Nammensma Kropff, John Snape (Chair, CIMMYT Board of Trustees), Nicole Birrell (CIMMYT Board Member), Denis Huneault (Director of Business Services), Pramod Aggarwal (Regional Program Leader, CCAFS), Michelle Guertin (Senior Manager, Project Management), Jean-Flavien Le Besque (Global Human Resources Manager) and Arun Joshi (Country Representative).

ICRISAT Director General David Bergvinson welcomed the delegation and emphasized the continuing need for system-level synchronization among CGIAR centers. An introductory presentation highlighted the activities of the CIMMYT-Hyderabad team, ranging from upstream marker discovery and phenotyping and informatics tool development to mid-stream adaptive research to downstream hybrid deployment through seed partners and engagement  with farmers through on-farm trials and demonstrations.

The key to this success is strong partnerships with national partners, the seed industry and other CGIAR centers. The ensuing discussion centered around the need for a CIMMYT center of excellence (or CIMMYT Academy) in the region as a way to systematize, strengthen and sustain partnerships.  The need for “out of the box” solutions to drive CIMMYT’s agenda through cost recovery models of research expenses, within the “not-for-profit” mandate of the CG, also stimulated a lot of discussion.

Martin Kropff’s presentation highlighted the relevance of CIMMYT’s work, the new “ONE CIMMYT” strategy and the interesting feedback from CIMMYT’s recent staff survey. Kropff also had an exclusive meeting with the female staff of CIMMYT-Hyderabad. The delegation was given a tour of CIMMYT facilities and fields, and had the opportunity to interact with national staff. This intense and important visit concluded with a meeting with ICRISAT’s Management Group.

Beating the odds: Indigenous female scientist gets Mexico’s National Youth Award

EL BATAN, Mexico (CIMMYT) — Tania Martínez, Ph.D. fellow with the International Maize and Wheat Improvement Center (CIMMYT), received the Mexican National Youth Award for her outstanding performance in academic achievement from Mexican President Enrique Peña Nieto.

Established in 1975, the award recognizes Mexican youth whose dedication inspires peers and exemplifies the values of personal growth and community development.

Martínez is at CIMMYT studying for her doctorate with the Knowledge, Technology, Innovation Group at Wageningen UR University in the Netherlands. She follows technology trajectories and processes of social inclusion/exclusion within them. As part of her research she is studying conservation agriculture, a set of farming practices based on minimal soil disturbance, permanent soil coverage and use of crop rotations, in Mexico’s Bajio region. Under MasAgro – a large Mexico-CIMMYT initiative – she is involved in work that helps smallholder farmers in breeding to improve their prized local maize varieties, and also looks at how farmers can access information through information and communications technology.

In 2001 at the age of 14, Martínez left her home of Tamazulápam Mixes, an indigenous village in the northern mountains of Oaxaca, to study at the Autonomous University of Chapingo in Central Mexico.

Her achievements are noteworthy. Of the more than 15 million indigenous Mexicans – about 15 percent of the country’s population – over a quarter of adults don’t have a single year of education and only 26 percent of women work or take part in other economic activities.  Mexico’s indigenous citizens are among the country’s poorest and most marginalized.

“I decided to study agronomy because I was raised in the countryside and rooted to the land,” Martínez said. “In Chapingo, though, I met people who didn’t know there were places in Mexico without electricity, drinkable and sanitary drainage systems or even access roads. “Yes, they exist!’ I would reply. ‘I actually have been in places, they exist in many regions of Mexico”’

Nearly 30 percent of indigenous peoples in Mexico live without running water and 66 percent of households cook with wood and charcoal.

Prior to undertaking Ph.D. studies, she received a Fullbright scholarship to study at the University of Arizona, where she obtained a master’s degree in agricultural and biosystems engineering focusing on water management, irrigation and bioethanol production from sweet sorghum.  Martínez then went on to work at CIMMYT as an intern and consultant before beginning her doctoral research with the organization’s socioeconomics program in 2013. Martínez credits meeting Conny Almekinders – her current professor and supervisor at Wageningen – and Carolina Camacho, a postdoctoral fellow with CIMMYT’s socioeconomic program, who specializes in social analysis of agricultural technologies, as the source of inspiration for pursuing her Ph.D. in the same topic.

“I hope more people are willing to help those who’ve not had the same opportunities and support I have had, to help change their reality,” Martínez said. “I’m grateful to all those who’ve helped me along the way, especially CIMMYT and the many researchers and people I have met in this long journey.”

As part of her National Youth Award, Martínez plans to donate books to libraries in marginalized communities and help develop policies that help these communities.

A Chat With: Mark Lynas – sustainable agriculture key to food security amid climate change

EL BATAN, Mexico (CIMMYT) – Sustainable agriculture must be adopted globally if natural ecosystems are to be protected as food production increases to feed a projected population of 9.7 billion by 2050, said author and environmentalist Mark Lynas.

An immediate move to transform overall agricultural practices is needed to overcome the challenges of climate change and biodiversity loss, said Lynas who will speak at a conference to mark the 50th anniversary of the International Maize and Wheat Improvement Center (CIMMYT) in September.

Rather than expanding agricultural production into new terrain, Lynas, who is a visiting fellow at the Cornell Alliance for Science, funded by the Bill & Melinda Gates Foundation said sustainable intensification agricultural practices are preferable to boost productivity while preserving environmental equilibrium.

A former critic of genetically modified organisms (GMOs) Lynas changed his mind when he said it became clearer to him that there was a scientific consensus that genetic engineering was safe. In his current role at Cornell University, he now advises on public sector biotechnology in developing countries.

Lynas will deliver a presentation during a session entitled “Future Landscapes” at the CIMMYT 50th anniversary conference on Sept. 29, 2016.

He shared some views on the future of agriculture in the following interview.

Q: What are the key challenges the world faces?

Well, it’s become something of a cliche now to talk about how we need to double world food supply by 2050 in order to feed the growing human population. I’m keen to add an environmental perspective to this statement. We need to double world food production but at the same time to shrink the area of cultivated land in order to protect natural ecosystems. With the ongoing crises in climate change and biodiversity loss, we cannot afford to plow up the rain forests or other ecologically valuable areas, so the only viable option is to sustainably intensify existing cultivated areas, hopefully with “rewilding” of spared lands. Obviously, this is a broad-brush assertion, and there is a lot of geographical complexity and nuance underlying this, that we should not forget.

Q: How does your area of specialization address these challenges? What innovation do you see improving agriculture?

I’m particularly focused on biotechnology in agriculture, which can help improve sustainability in many ways. Basically, if you can move from chemistry to biology in addressing challenges, from water use to yield to pest control, so much the better for the environment. An example would be the use of the Bt gene, which produces a protein in the plant that is toxic only to the pest itself and harmless to everything else, including us. That’s a much more sustainable option than indiscriminate insecticide sprays that have serious environmental and health impacts. However, because of their total opposition to genetic engineering, anti-GMO campaigners end up defending continued pesticide use, which is a very strange place for supposedly green activists to be. I’ve seen this at first hand in Bangladesh with the campaign against Bt brinjal. Anti-science superstition of this sort can end up being very environmentally damaging.

Q: What outcomes would you like to see from the CIMMYT conference?

CIMMYT experts were co-authors on a recent paper,  “Reducing emissions from agriculture to meet the 2 °C target” in Global Change Biology, that challenged the agriculture sector to reduce its greenhouse gas emissions significantly — by 1 billion tons a year — in order to contribute to meeting the 2 degrees C international climate change target. I thought this was a great initiative and I would love to see more attention given to it by other stakeholders at the CIMMYT conference. I really hope it becomes a talked about target that ends up being matched with real commitments and actions in the field.

A Chat With: U.S. nutritionist Julie Miller Jones speaks out about GE crops

EL BATAN, Mexico (CIMMYT) – Leading nutritionist Julie Miller Jones aims to bust myths about biotechnology

by educating the general population on the benefits she believes genetically engineered (GE) crops can play in ending extreme hunger and malnutrition.

A shift away from the perception that GE crops are unsafe for the environment and human health is needed if they are to live up to their potential to increase food production and improve nutrition to meet the needs of growing global population, said Miller Jones who will speak at a conference to mark the 50th anniversary of the International Maize and Wheat Improvement Center (CIMMYT) in September.

Hunger and malnutrition are barriers to sustainable development, because they lead to lowered productivity, diminished health and limit the ability to improve livelihoods, she said. There are nearly 800 million people who suffer from hunger worldwide, the majority in developing countries, according to the United Nations.

A recent report released by the U.S. National Academies of Sciences, Engineering and Medicine said there is no substantiated evidence that foods from GE crops are less safe than foods from non-GE crops. Miller Jones said the general public must be educated about how biotechnology can safely improve food crops and contribute to nourishing a global population projected to grow by more than 2 billion by 2050 to more than 9.7 billion.

GE technologies enable the insertion from one species to another of genetic material (DNA) responsible, for example, for the production of vitamin precursors, such as pro-vitamin A carotenoids. Specific genes from maize, daffodil or carrot, placed in a staple grain, can help address vitamin A shortages in many regions, said the nutritionist. Conventional breeding does not have this ability to insert desirable genes from one species to another, and GE technologies can therefore enhance the contribution of plant breeding in addressing significant public health problems, she said.

Miller Jones has followed wheat-breeding developments over the years. She is a big fan of Norman Borlaug, the late CIMMYT wheat breeder and 1970 Nobel Peace Prize laureate known as the Father of the Green Revolution for the high-yielding wheat varieties he produced, which are credited with saving more than a billion lives in the developing world.

Miller Jones is outspoken about the negative consequences of gluten-free diets and has written several research papers that dispel myths generated by claims that the protein found in wheat is unhealthy.

She is a certified nutrition specialist who is also a distinguished scholar and professor emeritus of nutrition of nutrition at St. Catherine University in St. Paul, Minnesota. Interested in all aspects of nutrition science, she is actively involved in educating consumers against myths about nutrition and food safety. Currently, she is a scientific advisor to a number of groups such as the Healthy Grains Institute and the Grains Food Foundation that promote healthy diets and educates consumers on the benefits the right balance of grain-based foods.

Jones, who will speak during Session Five on “Future Landscapes” at the CIMMYT 50th anniversary conference on Sept. 29, 2016, shared some insights on the future of agriculture in the following interview.

Q: What is significant about CIMMYT: What role has CIMMYT played in your area of work?

CIMMYT and Norman Borlaug have always been inspirations to me ever since I began my graduate work at the University of Minnesota nearly 50 years ago. I’m interested in nutrition and feeding the world, I taught students about the Green Revolution and the achievements of Borlaug and CIMMYT in the world food supply section of my class on current issues throughout my entire academic career.

Q: What are the key challenges the world faces?

Producing enough food and communicating about the risks and benefits of anything we do. Communicating that there are risks to using GE crops, but these are assessed on a case-by-case basis.. What hasn’t been communicated effectively, so that the average person can understand and not fear the technology, is the risk of not using GE and other agricultural advancements. It’s ironic to me that those claiming to be interested in the environment often reject technologies that enable the use of fewer inputs and scarce resources and they do it in the name of the environment. All must communicate this in a non-defensive, clear way.

Q: How does your area of specialization address these challenges?

As a nutritionist and communicator, I want to work with breeders to ensure that nutrients are one of the aspects that are included in breeding programs. Further, I want to work with others to develop effective strategies to explain advancements in agriculture and plant breeding to reduce consumers’ fears and ease their acceptance and adoption.

China’s vice premier ushers in new era of agricultural collaboration

TEXCOCO, Mexico (CIMMYT) — A new collaborative program promising to train Chinese Ph.D. and postdoctoral students annually at the International Maize and Wheat Improvement Center (CIMMYT) builds on the three decade relationship the organization holds with China.

The memorandum of understanding was signed during China’s Vice Premier Liu Yandong’s visit to CIMMYT on 9 August by the Secretary General of the Chinese Scholarship Council Liu Jinghui and CIMMYT Director General Martin Kropff.

“In the face of climate change, water shortages and other challenges, innovative strategies to agricultural development are necessary for China’s future development,” Yandong said. “We hope to strengthen cooperation with CIMMYT — this will have a tremendous effect on both China and the world.”

Since 1970, more than 20 Chinese institutes have been involved in germplasm exchange and improvement, conservation agriculture and capacity building, with 56 Chinese researchers receiving their doctoral degrees with CIMMYT. Since the CIMMYT-China Office was opened in 1997, 26 percent of wheat grown in China has derived from CIMMYT materials.

During the visit, the vice premier discussed China’s new five-year plan (2016 – 2020) that focuses on innovation, international cooperation and green growth, to modernize agriculture in an environmental friendly way over the next 20 to 30 years.

Benefits of three decades of international collaboration in wheat research have added as much as 10.7 million tons of grain – worth $3.4 billion – to China’s national wheat output. Eight CIMMYT scientists have won the Chinese Friendship Award – the highest award for “foreign experts who have made outstanding contributions to the country’s economic and social progress.”
