NEW DELHI, India (CIMMYT) — Major impacts of CIMMYT’s Cereal Systems Initiative for South Asia (CSISA) include success in increasing access to and affordability of modern farming technologies and practices for smallholder farmers across India, according to a new report.

The initiative, which began in 2012, resulted in positive impacts and has built a robust service economy to improve access to new technologies for smallholder farmers, said Andrew McDonald, CSISA project leader.

“India has a large number of smallholders, especially in eastern states where the average landholding size is decreasing and machine ownership by farmers is often not economically viable,” McDonald said. “Unless we build a robust service economy to facilitate uptake of new technologies, they would be beyond the reach of most smallholders.”

CSISA has developed a network of nearly 2,000 service providers in eastern India over the past three years to accelerate the expansion of sustainable intensification technologies, resulting in improved yields of up to 20 percent and increased farmer incomes through cost savings of $100 per hectare, the publication reports.

The report also details CSISA’s contribution to increased adoption of climate-resilient practices such as early planting of wheat and the use of zero-tillage seed drills, which help farmers overcome labor shortages during rice cultivation through mechanical rice planting.

“CSISA has built a compelling body of evidence for the importance of early planting to combat the negative effects of rising temperatures,” McDonald said.

“As a result, public perception and official recommendations have changed, and more than 600,000 farmers are now planting wheat earlier in the Indian states of Bihar and Uttar Pradesh.”

Additionally, CSISA helped popularize hybrid maize, which has increased yields and improved food security.

“Enhancing the productivity of the rice-wheat cropping systems in South Asia’s Indo-Gangetic Plains is essential for ensuring food security for more than 20 percent of the world’s population,” said McDonald. “CSISA, in close collaboration with national wheat programs, has released new wheat varieties with higher yield potential, which perform well even in stress-prone areas.”

These results were achieved during CSISA’s second phase, from 2012 to 2015, through collaborative work with national research and extension systems, research institutes, state governments, non-governmental organizations, private companies and farmers,.

CIMMYT team wins CCAFS recognition

Written by on December 22, 2015. Posted in News.

On 29 April, CIMMYT had a double reason to celebrate, picking up the award for “Best gender paper” and “Best science paper” (along with Bioversity), at the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) Science Conference in Copenhagen. The conference was part of a series of CCAFS meetings held from 29 April – 02 May, and was attended by various CIMMYT staff.

The best gender paper, titled ‘Adoption of Agricultural Technologies in Kenya: How Does Gender Matter?’ and co-authored by Simon Wagura Ndiritu, Menale Kassie and Bekele Shiferaw, highlighted the differences between technologies adopted on female- and male-managed farm plots in Kenya. They found that whilst there were gender differences in the adoption of technologies such as the use of animal manure, soil and water conservation, other differences in the use of chemical fertilizers and improved seed may stem from the varying levels of access to resources for men and women, rather than gender itself. “This recognition inspires me to put more effort to produce more quality research that will bring excellent distinction to CIMMYT and myself,” said Kassie, while Ndiritu said “it is an encouragement to a young scientist,” adding that he is looking forward to having the paper published.

The winning science paper, ‘Assessing the vulnerability of traditional maize seed systems in Mexico to climate change’, was authored by David Hodson (FAO), and Mauricio Bellon (Bioversity) and Jonathan Hellin from CIMMYT. With climate change models predicting significant impacts in Mexico and Central America, particularly during the maize growing season (May – October), the paper assessed the capacity of traditional maize seed systems to provide farmers with appropriate genetic material, under the anticipated agro-ecological conditions. Their results indicated that whilst most farmers will have easy access to appropriate seed in the future, those in the highlands will be more vulnerable to climate change and are likely to have to source seed from outside their traditional supplies, entailing significant additional costs and changes to the traditional supply chain.

To share the good news, the Socioeconomics program hosted a get-together with the team in Nairobi, Kenya. During the cake cutting ceremony, the best gender paper award was dedicated to women farmers from Embu and Kakamega in Kenya’s Eastern and Western Provinces, where the data was collected. The Nairobi team also took the opportunity to initiate monthly seminars in order to share research findings hosted by the Global Maize Program and the Socioeconomics program and promote regular interaction among the team. The program directors, Bekele Shiferaw and B. M. Prasanna nominated Dan Makumbi, Hugo De Groote, Sika Gbegbelegbe, Fred Kanampiu, and Sarah Kibera, to form the organizing committee for the seminars.

CIAT Director General visits CIMMYT

Ruben Echeverría, Director General of the International Center for Tropical Agriculture (CIAT) headquartered near Cali, Colombia, gave a brown bag seminar on “An evolving LAC strategy … from international donors to country partnerships,” where he presented an overview of CIAT’s work and strategic initiatives.

An alumnus of CIMMYT, Echeverría conducted part of his Ph.D. thesis research in the mid-1980s, in the field in Mexico and Guatemala. At the seminar, he emphasized the need for research centers such as CIMMYT and CIAT to embrace the private sector and partner with agribusiness to collaborate on new potential lines of research.

Echeverría also discussed the donor environment in Latin America, and the need to build stronger connections with national governments for future support. In addition to the seminar, Echeverría met with CIMMYT staff and key stakeholders to discuss continued collaboration between the centers and future partnership in Colombian maize projects.

Cross-regional efforts produce a toolbar for direct seeding of maize

Written by on December 18, 2015. Posted in News. 1 Comment on Cross-regional efforts produce a toolbar for direct seeding of maize

Cheap, light, versatile… and locally manufactured

Direct seeding of maize using a two-wheel tractor has been made possible over the past decade or so by manufacturing companies in China, India, and Brazil (among others) that produce commercially available seeders. Several of these seeders have been tested for the past two or three years in Ethiopia, Kenya, Tanzania, and Ethiopia under the Farm Mechanization and Conservation Agriculture for Sustainable Intensification (FACASI) project supported by the Australian International Food Security Research Center (AIFSRC).

One of the best performing commercially available seeders (in terms of field capacity, precision in seed rate and planting depth, crop emergence, etc.) is manufactured by the Brazilian company Fitarelli. However, this seeder is expensive (above US$ 4,000), difficult to maneuver (especially in small fields), and lacks versatility (minimum row spacing is 80 cm).

In response, several initiatives have aimed at producing toolbar-based seeders to be manufactured locally and cheaply, that could be used in different configurations (to seed one, two, or more rows) and could perform other operations (such as forming planting beds). One such toolbar is the Gongli seeder, which is well suited to sow small grain crops such as wheat and rice in Asian fields, but not maize under typical field conditions in Africa. Two years ago, Jeff Esdaile, inventor of the original Gongli, and Joseph Mutua, from the Kenya Network for Dissemination of Agricultural Technologies, produced a modified version of the Gongli – the Gongli Africa + thanks to funding from CRP MAIZE (as reported in Informa No. 1862). In parallel, another toolbar using a different design was produced by Jelle Van Loon and his Smart Mechanization/Machinery and Equipment Innovation team at CIMMYT-Mexico.

Both the Gongli Africa + and the Mexican toolbar have their strengths and their weaknesses. Both have also been judged as too heavy by local service providers. Thus, CRP MAIZE and the Syngenta Foundation for Sustainable Agriculture co-funded a two-week session (8-27 October) in Zimbabwe to develop a “hybrid toolbar” having the strengths of both the Gongli Africa + and the Mexican toolbar but weighing under 100 kg. Jeff Esdaile, Joseph Mutua, and Jelle Van Loon spent the entire two weeks manufacturing three prototypes of the hybrid at the University of Zimbabwe. The two-week session also served as hands-on training for staff of three of Zimbabwe’s major manufacturing companies of agricultural equipment (Zimplow LTD, Bain LTD, and Grownet LTD) as well as representatives of the informal sector.

The hybrid toolbar is expected to sell for a quarter of the price of a Fitarelli seeder, although its performance (in terms in term of field capacity, fuel consumption, precision, and crop emergence) is expected to be equivalent. Its weight suits the needs of local service providers better and it is infinitely more versatile (several configurations are possible depending on the desired row spacing, soil conditions, the amount of mulch, etc.). The hybrid toolbar will be thoroughly tested in Zimbabwe during the coming months. A prototype will be shipped to Bangladesh and another to Mexico for further testing and to share the design.

Agronomic practices that can close the wheat yield gap in the Ethiopian highlands are well known: row planting, precise fertilizer application, timely planting, etc. But their implementation generally increases the demand for human labor and animal draft power. And the availability of farm power in the Ethiopian highlands is stagnating, or even declining. The cost of maintaining a pair of oxen is becoming prohibitive for most farmers. Also, the rural population is aging as a result of young people migrating to the fast-growing cities of Ethiopia in search of more rewarding livelihood opportunities than farming.

Gender bias may limit uptake of climate-smart farm practices, study shows

EL BATAN, Mexico (CIMMYT) — Farmer education programs that fail to address traditional gender roles may sideline women, limiting their use of conservation agriculture techniques, which can boost their ability to adapt to climate change, a new research paper states.

Conservation agriculture involves minimal soil disturbance, permanent soil cover and the use of crop rotation to simultaneously maintain and boost yields, increase profits and protect the environment. It contributes to improved soil function and quality, which can improve resilience to climate variability.

Although some scientists believe that such techniques have the potential to reduce greenhouse gas emissions and increase carbon sequestration, which can help mitigate the impact of global warming, it is important to note that the potential benefits of certain aspects of conservation agriculture — particularly not tilling the soil — have been overstated, write the authors of the study from the International Center for Maize and Wheat Improvement (CIMMYT) and the Research Program on Climate Change Agriculture and Food Security (CCAFS).

Titled “Gender and conservation agriculture in east and southern Africa: towards a research agenda,” the paper discusses the lack of research conducted into interactions between conservation agriculture use and gender. It proposes a research agenda that will better understand how African farming systems remain strongly stratified by gender.

Despite an increase of women smallholder farmers throughout sub-Saharan Africa – one of the most vulnerable regions to climate change worldwide – agricultural service suppliers and policymakers remain “locked into the conceptual norm of the primary farmer as male,” said co-author Clare Stirling, a senior scientist in the Sustainable Intensification Program at CIMMYT.

“The ability of women-led households, or male-headed households with women as primary farmers, to adopt conservation agriculture may be compromised if government policies, extension systems and other actors continue to design interventions and target information and training around the conceptual norm of the male-headed household,” Stirling said, adding that a gender-sensitive approach should become part of mainstream research.

“Overall, normative conceptualizations of ‘farmers’ can result in inappropriate targeting and ineffective messaging,” she said.

There is almost no understanding of how gender relations in smallholder agriculture – particularly with regard to decision-making over technology adoption, roles and responsibilities for specific farm tasks – may influence the likelihood of adopting conservation agriculture techniques, the paper states.

The costs and benefits of conservation agriculture adoption to women themselves — in terms of income, labor deployment, contributions to food and nutrition security and relative decision making power at household and community level, remain largely unknown.

In sub-Saharan Africa, about 30 percent of the population is undernourished, and the area has the highest projections for population growth by 2050, the paper states, adding that a projected 2 degree temperature increase related to global warming is likely to be accompanied by reduced rainfall and increased variability of weather patterns.

These factors will put pressure on agricultural systems that are largely small scale, low input, rain fed and already struggling to feed the population, according to the report. Cereal yields in the region are low and stagnant, averaging 1.3 tons per hectare, compared with 3 tons per hectare in the developing world overall.

Women and men typically take on distinctive, sex-segregated roles, responsibilities and tasks in agricultural production systems. While men and women may have different rights and responsibilities for different crops and livestock products, women are typically responsible for household tasks and caring roles.

“Women more than men are involved in a zero sum game, a closed system in which time or energy devoted to any new effort must be diverted from another activity,” the report states. Access to land, which in many sub-Saharan African countries is managed under customary law, or a patchwork of statutory and customary laws – is also complex and under-researched in terms of understanding the associations between gender, decisions about land management and the willingness of farmers to engage in conservation agriculture or indeed any new intervention that involves a delay in returns, according to the paper.

Towards inclusive and sustainable grain marketing

Written by on December 4, 2015. Posted in News.

To build an adequate strategy for marketing basic grains that includes incorporating small- and medium-scale farmers into the market, it is important to consider aspects such as sustainable production and farm organization and the information farmers may have on these subjects. But how can we help farmers organize themselves, plan their work, determine their group requirements, and access timely information for strategic decision making? How much additional value does a supplier or group of suppliers that are efficient, sustainable, and reliable bring to agro-industries or other grain buyers? To answer these and other questions, the MasAgro program organized its first forum on grain marketing titled “Towards Inclusive and Sustainable Grain Marketing” at CIMMYT headquarters on 9 November.

Víctor López Saavedra, leader of MasAgro Productor, welcomed the participants and highlighted the impacts that the MasAgro initiative has had up to now in Mexican farmers’ fields. He also said that the concept of inclusive and sustainable commercial relations is at the core of MasAgro’s interventions in the area of marketing. The event included three panels that provided a space for representatives of the different sectors involved in maize production systems and grain marketing to exchange knowledge and experiences.

The first panel titled “Strategies for improving farmers’ market linkages” was led by María del Pilar Alcacio, SDAyR Guanajuato; Mayte Reyes, Consultative Group on Agricultural Marketing -GCMA; and Marco Antonio Cabello, FIRA. This panel discussed adequate strategies for fostering and strengthening the associations among farmers, factors that help them use contract agriculture schemes, as well as the best mechanisms for doing so.

The second panel, “Market opportunities for grain production systems based on sustainable production intensification,” highlighted the advantages of sustainable production and smart information access and use as ways of linking farmers to markets. Adolfo Ruiz, agricultural operations manager at PepsiCo, and Greta Villaseñor, executive director of the Business Council of the Maize Industry and Derivatives, talked about the concrete opportunities that their businesses provide for including small- and medium-scale farmers in their supply chains. Other panel participants were Vinicio Montiel, producer from the Farmer Association of Río Fuerte Sur-AARFS AC, and Roberto Rendón, academic from the University of Chapingo-CIESTAAM.

The third panel presented cases of farmers who had successfully linked up with markets. Invited farmers shared their experiences and marketing organization strategies, as well as the challenges they faced when seeking new marketing channels. Farmers who took part in this panel were Enrique Abadía, from the Innovative Farmers Group of Espinal, state of Morelos; Marcelino Vázquez Ramírez, lead farmer of Agro-productores Dobladenses SPR, and Urbano Godoy, barley producer from the state of Hidalgo. The panel discussion was closed by Amado Ramírez Leyva from Itanoní, who described how native maize landraces can become market niches.

To wrap up the event, Bram Govaerts, leader of Sustainable Intensification for Latin America, summarized the conclusions reached, which were regarded as recommendations to follow. It was agreed that since adoption of sustainable technologies directly affects the quality and competitiveness of farm production, it is absolutely essential to promote it. The need to strengthen the association among farmers and stimulate their market linkages, and to focus more public and private resources on improving the impact on key actors was mentioned. It was also noted that although large-scale marketing is necessary, it is not the only possible solution: local marketing can also be a desirable and successful strategy.

It is expected that concrete tools that foster environments that favor incorporating farmers into the market and establishing more inclusive and sustainable linkages will continue to be disseminated through this type of fora. This first forum was a definite step towards achieving this goal.

Buena Milpa participates in the lamb and agrobiodiversity fairs in Guatemala

Buena Milpa is the Sustainable Intensification Strategy for Latin America promoted by CIMMYT in Guatemala. It aims to foster innovation to reduce poverty and malnutrition, and enhance the sustainability of maize systems in the Guatemalan highlands.

Recently the Buena Milpa Project took an active role in the XX Lamb and VII Agrobiodiversity Fairs held in the Cuchumatanes Sierra, Chiantla, Huehuetenango, Guatemala, which brought together different social organizations and inhabitants from several departments (states) in the country’s western region.

Each year, the Association of Cuchumatan Organizations (ASOCUCH), Buena Milpa’s social institution, holds agrobiodiversity fairs where farmers exhibit and exchange varieties of maize, potato, bean, yam, and other crops that they grow on their farms. The objective is to promote the protection and conservation of agricultural and livestock diversity (especially of native maize). During the event, there were tables with displays on themes such as agrobiodiversity to support food security, climate change, and the environment.

During the fair, Buena Milpa made presentations on the work being done in the western region, where the general objective is to foster innovation to reduce poverty and malnutrition, while enhancing the sustainability of maize systems. Maize fields there are diversified by sowing amaranth, which is an important component of the region’s human diet. Amaranth tastings were held to emphasize that it’s also important to consume it. Informative materials were distributed and the participants were made aware of the importance of conserving and protecting native maize, in the Mayas’ native tongues (mam and popti’).

The Buena Milpa team also provided a space where girls and boys of different ages could take part in learning exercises with seeds of maize and other crops in order to teach them to protect and conserve nature and the native maize varieties. The reason for holding these activities for girls and boys was to allow the women to participate actively in the events. The social and economic reality of rural native women is complex, and they have no one to look after their children. For this reason, they are forced to take them along to these events, where they cannot pay full attention to the presentations because they are keeping an eye on their children.

These CIMMYT-led activities raised awareness among the region’s inhabitants of the importance of conserving and protecting native maize, adopting crop diversification, and conserving soil and water as a vital part of sustainable native farming in Guatemala’s highlands. The participants were also made aware of the value of women as agents of change, as well as the importance of fostering love for nature and protection of native seeds in young children.

New findings on gender gap in conservation agriculture

Despite wide-ranging, in-depth conservation agriculture studies conducted over many years, almost none consider gender and gender relations as a factor that may explain low adoption rates, according to the recently published paper “Gender and conservation agriculture in East and Southern Africa: towards a research agenda.”

The paper examines research to date on the interactions between conservation agriculture interventions – meaning minimal soil disturbance, permanent soil cover and crop rotation that can simultaneously boost yields, increase profits and protect the environment – and gender in East and Southern Africa and sets out a research agenda based on gaps observed. Given the increasing interest in conservation agriculture due to climate change impacts in the region, the authors also argue that greater attention to gender is needed in order to ensure successful interventions. The following Q&A with one of the study’s authors, Clare Stirling, CIMMYT Senior Scientist with the Sustainable Intensification Program based in Wales, UK, details the study’s findings and what is needed to ensure gender is included in future conservation agriculture interventions.

Q: How do conservation agriculture practices interact with gender?

A: There are many known and unknown ways in which conservation agriculture interacts with gender and the purpose of this paper is to review the evidence and identify gaps that exist. conservation agriculture is knowledge-intensive and can also be labor-intensive and, along with many soil improvement technologies, involves long-term investment with delayed returns. This clearly has important implications for women, as their ability to invest will depend on many factors such as entitlements, access to information, and their ability to act upon it.

If we take labor requirements as an example – many studies highlight labor shortages as a constraint to the adoption of conservation agriculture, particularly when zero tillage is not complemented by the application of herbicides. Without herbicide use, conservation agriculture techniques for land preparation increase weeding over and above plowing and ridging by as much as three times in maize production. In East and Southern Africa, this burden falls largely on women as weeding is largely a woman’s task. Studies conducted in several countries show that where (frequently subsidized) herbicides have been used, the release of women and children from weeding tasks results in multiple benefits, including more children attending school and more time for women to engage in income-generation activities.

Q: Why has gender been left out of many conservation agriculture studies to date?

A: I am not sure that this is a question that should be posed specifically in relation to conservation agriculture but could be asked of agronomic research in general. Things are improving, but I would suggest that the reason has been that gender is a challenging and complex issue that takes many of us out of our comfort zone both professionally and perhaps personally. It requires an interdisciplinary approach and a set of skills that many agricultural research centers simply have too limited a supply of and I include in this a critical mass of female research staff of sufficient seniority. Without this critical mass of gender expertise, agronomic research will continue to be designed and implemented according to the “male agronomist” norm.

Q: What impact has this had on conservation agriculture adoption in East and Southern Africa?

A: lncreased feminization of labor in smallholder agriculture has resulted in major changes in the roles and responsibilities of women in rural Africa, but still agricultural service suppliers and the wider policy environment in general remain locked into the conceptual norm of the primary farmer being male. This inevitably results in inappropriate targeting of research, extension services, and policy, and logic would tell us that it has also contributed to low adoption rates of conservation agriculture.

As the paper explains, the new norm of the “female primary farmer” has not resulted in their widespread recognition as such by external agencies or indeed within their communities. The ability of women-led households, or male-headed households with women as primary farmers, to adopt conservation agriculture may be compromised if government policies, extension systems, and other actors continue to design interventions around the conceptual norm of the male-headed household. This needs to change.

The paper summarizes the gender-related questions that remain to be addressed with regard to conservation agriculture, and there are many. There are overarching questions relating to intra-household decisions making, access to services, and labor. In addition, there are many more questions relating to specific aspects of conservation agriculture, such as the impacts of minimum tillage and weeding on labor; opportunity costs and how increased requirements are met; opportunities, constraints, and trade-offs of conservation agriculture-based crop diversification; and the tailoring of conservation agriculture-based information and training to women farmers.

Q: Moving forward, how can researchers address the gender gaps in conservation agriculture in their studies?

A: Gender-sensitive research needs to be mainstreamed into projects. In order to achieve this, we need more multidisciplinary teams including both male and female researchers of similar seniority. While there is a decent body of gender research on the socioeconomic aspects of agricultural technologies such as barriers to uptake and extension services, it seems that there is still a large gap in gender-sensitive agronomic research. What are the implications for gender of increased weeding, need for planting basins, crop diversification, and residue retention? All very basic questions that still need answering. So moving forward, we need more research that involves gender specialists working closely with agronomists on the design, implementation, evaluation, and scaling out of conservation agriculture-based practices.

Study reveals challenges in southern Africa’s soil carbon uptake

Written by on November 23, 2015. Posted in Features. 1 Comment on Study reveals challenges in southern Africa’s soil carbon uptake

A new study led by ETH Zürich graduate Stephanie Cheesman, along with CIMMYT senior agronomist Christian Thierfelder, Neal S. Eash from the University of Tennessee, Girma Tesfahun Kassie, ICARDA, and Emmanuel Frossard, professor at ETH Zürich, found limited increase in carbon sequestration under conservation agriculture (CA) after up to seven years of practice. In this interview, Cheesman tells us why carbon sequestration is such a complex issue in Southern Africa and what this study reveals about how it can improve.

Q: Why is increasing soil carbon important?

A: Besides the hype about sequestering carbon to contribute to climate change mitigation, carbon is an integral part of soil organic matter (also referred to as “humus”), which is possibly the most well-known fertility component of a soil. Soil carbon has strong influence on soil structure, water infiltration, as well as the capacity of the soil to retain water and nutrients that are required for plant growth. Degraded soil has only a little soil carbon and, hence, low fertility and nutrient- (and water) holding capacity.

Q: What were you hoping this study would reveal?

A: Although the study trials had been running for only seven years, I was hoping to show a clearer trend towards an increase in soil carbon under CA as compared to conventional practices (CP) in Southern Africa. We were surprised that, in most cases, the carbon under CA was at the same level as the conventional control treatment, with a few exceptions. Nevertheless, this is one of a very few studies where soil carbon stocks in CA systems have been analyzed across a wide range of Southern African agroecologies. I am now very happy to share this data with the wider research community.

Q: What factors limit carbon sequestration in Southern Africa?

A: There are a range of factors that limit carbon sequestration. Our findings suggest low productivity to be one of the main bottlenecks. Farmers have to decide if they should feed the crop residues to the soil or to their livestock. The long dry season from May to November and high temperatures further increase the mineralization of soil carbon, which can be twice as much as in temperate regions. Another factor that may limit carbon sequestration is the limited use of other strategies such as the integration of legumes or agroforestry species as intercrops in maize-based systems.

Q: Given the findings of this study, how can we increase soil carbon in Southern Africa in the future? Is conservation agriculture necessarily the answer?

A: Unfortunately, our study lacks initial carbon stock measurements, as this was tested on a very large set of on-farm trials and we never had enough financial resources to continuously test this from the onset. We could compare the difference between CA and CP but not how carbon stocks changed over time in the respective systems. Although some of the trial sites were up to seven years old, this is a comparably short time to increase the level of carbon in such environments. From other long-term studies (mainly in the Americas), we know that tillage-based agricultural systems decrease carbon stocks. Thus, I would say that a system like CA where tillage is reduced and residues are “fed” to the soil will more likely maintain soil carbon and maybe gradually increase it in the longer term. Tillage-based agricultural systems also have much higher soil erosion loads which further decreases carbon, so CA is definitely an answer to reduce soil degradation.

CIMMYT’s mission is to “sustainably” increase the productivity of maize- and wheat-based systems to reduce poverty and hunger. By combining improved varieties with sustainable intensification practices, CIMMYT does its best to give smallholder farmers options to improve their productivity and livelihoods. Feeding the soil with residues is one strategy to maintain or gradually increase soil carbon but we should not forget the immediate needs of farmers.

On 16-31 October 2015, the Sustainable Intensification of Maize and Legume Systems for Food Security in Eastern and Southern Africa (SIMLESA) project undertook a two-week long Mid-Term Review (MTR) of its agricultural research and development activities on station and on farm. SIMLESA undertook this review to assess project performance and recommend actions to refine activities. The last MTR was carried out in 2012.

To wrap up the review, a two-day meeting was held with the participation of 40 people, including representatives from the Australian Centre for International Agricultural Research (ACIAR), Queensland Alliance for Agriculture and Food Innovation, the International Center for Tropical Agriculture (CIAT), the International Livestock Research Institute (ILRI), the national agricultural research systems (NARS) of Ethiopia, Malawi, Mozambique, Kenya, and Tanzania, and CIMMYT scientists from Ethiopia, Kenya, and Zimbabwe.

Maintaining a diverse landscape in maize- and wheat-based systems to ensure a nutritious diet

Arsi Negele, in southern Ethiopia, is a paradox: local farmers are blessed with good soils, good and reliable rainfall, relatively large farms, and good market connections, but the local hospital in Gambo admits, on average, one child per day suffering from acute malnutrition (kwashiorkor and marasmus). The main cause? A grain-based diet that lacks proteins, vitamins, and other micronutrients. Biofortified maize and wheat that include some of these missing elements could help. But diet diversification is probably the real answer.

East and Southern African countries need to formulate and implement appropriate policies to help smallholder farmers access technologies that will enable them to increase farm yields and improve crop resilience and nutrition to address poverty, food security, and economic growth, renowned Zimbabwean agricultural economist and academic Mandivamba Rukuni told a high-level policy forum.

Delivering the keynote address at the SIMLESA policy forum co-organized by CIMMYT and the Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA) in Entebbe, Uganda, on 27–28 October, Rukuni said this can only be achieved through a dramatic shift to help smallholder farmers produce sufficient food for themselves, plus generate income. “Such technologies include improved seed varieties and fertilizers, and better infrastructure, such as roads and small-scale irrigation,’’ said Rukuni. SIMLESA is funded by the Australian Centre for International Agricultural Research (ACIAR) and implemented by CIMMYT.

XXI Latin American Maize Meeting

Written by on November 13, 2015. Posted in News. 1 Comment on XXI Latin American Maize Meeting

Bolivia’s National Agricultural, Livestock and Forestry Innovation Institute (INIAF) and the CIMMYT-Colombia office organized the XXI Latin American Maize Meeting (XXIRLM) held in Santa Cruz de la Sierra, Bolivia, on 29-31 October 2015.

The meeting was organized within the agricultural innovation framework around four themes: genetic resources and biotechnology, genetic improvement, special and biofortified maize, and climate change and sustainable agricultural intensification. An expert gave a lecture on each one of the themes, followed by presentations by representatives of the participating institutions, which were reinforced by previously selected posters.

Bolivia has 11 million inhabitants and is self-sufficient in maize, producing 1.1 million tons on 430,000 ha each year. However, maize production could increase sustainably through the use of technologies such as improved seed and adequate crop management practices, including crop rotations (for example, with soybean on the 1.2 million ha sown to this crop). The goal of the XXIRLM was to discuss these and other subjects.

Johnny Cordero, Vice Minister of Rural Development and Lands, opened the meeting, which was attended by Carlos Osinaga, INIAF Director General, and Tito Claure, Coordinator of INIAF’s Maize Program. Juan Rissi, IICA representative in Bolivia, gave the first talk and said that in this age of productivity and competition, innovation is at the core of the agricultural sector’s tasks. Countries should therefore significantly increase their investment in research and development, strengthen the INIAs, and develop regional integration mechanisms to include INIAs, universities, research centers, the private sector, and farmer associations.

In the area of genetic resources, Terrance Molnar, CIMMYT, said that CIMMYT holds the world’s largest collection of maize genetic resources, with more than 27,000 accessions, whose potential is currently being assessed through the Seeds of Discovery project with the aim of providing genetic resources, knowledge, and tools that maize networks can use to accelerate the development of improved varieties that tolerate climate change and contribute to food security and sustainability. Four key objectives now being targeted are: drought tolerance, resistance to tar spot (Phyllachora maydis), resistance to maize lethal necrosis, and developing blue maize germplasm. Álvaro Otondo, INIAF Bolivia, mentioned that the area comprising northwestern Argentina and southwestern Bolivia has been proposed as a possible center of origin of maize based on ceramic artifacts found there that date from 7500-6200 BC.

Researchers at La Molina University evaluated 335 highland maize accessions from Peru’s central highlands and classified them into 22 races. The criteria that best differentiated these accessions were related to the crop’s vegetative stage and yield components. Researchers at CIF Pairumani, Bolivia, talked about the valuable experience they’ve had educating young students on genetic resource conservation using storytelling and the game of dominoes.

Ricardo Sevilla from La Molina University, Peru, proposed forming bulks of maize races using native germplasm and, when necessary, introductions. These bulks are later improved using recurrent selection to increase the frequency of favorable alleles of genes conferring adaptive traits, which are usually present in low numbers in native varieties. Selection gains of 5-10% have been achieved using this approach, depending on the selection criteria and the method used (half sibs, full sibs, self-pollinated families). In the area of biotechnology, researchers from the Universidad Mayor de San Simón and CIF Pairumani indicated they’re using new tools such as molecular markers, genomics, and another culture to develop haploids of some maize populations.

Luis Narro from CIMMYT and Sidney Parentony from EMBRAPA reviewed the history of maize breeding and came to the conclusion that breeding methods should exploit heterosis through the development of simple hybrids whose seed should be accessible to farmers at the right time, in places where they are needed, at a fair price. Hybrid seed use varies greatly in South American countries where double, triple, and simple hybrids are sown. For example, the area sown to hybrid seed covers more than 90% of the maize area in Argentina and Venezuela, 80% in Bolivia, and less than 50% in Colombia.

In Andean countries such as Bolivia, Ecuador, and Peru, farmers plant hybrid seed only of tropical maize (called hard yellow maize) (its use is above 80%). As for the Andean highland maize that is sown at altitudes above 2500 masl, the area sown to hybrid maize is zero, since all of the area is sown to open-pollinated varieties.

The convenience of using new technologies such as molecular markers, genomics, and doubled haploids to accelerate breeding progress was discussed. Molecular markers, genomics, and doubled haploids are being implemented in Argentina and Brazil, and doubled haploids are being produced in Chile. Other countries in the region such as Bolivia and Ecuador are interested in these technologies and have working agreements with CIMMYT.

Talks on genetic improvement were given by representatives from Bolivia, Colombia, and Ecuador, who said that new yellow maize hybrids with at least one CIMMYT parent have been released in their countries. In the case of Andean highland maize, ongoing work in Bolivia aims to increase maize productivity and incorporate resistance to ear rot into “cusco” type maize.

In the area of special and biofortified maize, CIMMYT researchers Félix San Vicente and Aldo Rosales highlighted the importance of maize varieties that are biofortified with provitamin A and high zinc content. They also reported CIMMYT’s progress in developing and releasing germplasm with high zinc, provitamin A, lysine, and tryptophan contents. They stressed the need to avoid grain losses due to poor storage and maintain the quality of products made from biofortified maize until they reach the consumer. High protein quality hybrids have been released in Bolivia and Ecuador in the past two years, and INTA Argentina is studying the nutritional quality of local maize.

In the area of special maize, representatives from Bolivia, Ecuador, and Peru presented their work on “purple maize,” a type of maize with high anthocyanin content in the grain, cob, and stalk, whose nutraceutical properties are due to powerful antioxidants that help control obesity, diabetes, and high blood pressure, as well as prevent colon cancer and other diseases. Consumption of soft drinks, cookies, and desserts made from this type of maize has increased greatly in countries such as Peru. This type of maize is only grown by smallholder farmers; therefore, linking the purple maize production system to the food industry would be an excellent means of improving the livelihoods of thousands of smallholder farmers who live in the poorest areas where this and other types of special maize are sown.

In the area of climate change and sustainable agricultural intensification, Kai Sonder from CIMMYT described changes in the weather at both the global and regional levels and highlighted the need to develop new varieties that tolerate multiple biotic and abiotic stresses. He also said it is necessary to set up networks that include germplasm evaluation and crop management practices adapted to farmers’ work environments and social conditions and promote sustainable agriculture, including precision agriculture, which means doing the right thing in the right place at the right time. Researchers from INTA Argentina and INIA Peru provided information on conservation agriculture and emphasized pest control, mechanization based on farm size and the type of crop, and recommendations on post-harvest management of maize grain. Argemiro Moreno did a field demonstration of the benefits of using the GreenSeeker to make more efficient use of nitrogen.

During the XXIRLM, replicas of an ear of maize of the “cusco” type were presented to outstanding maize researchers such as Gonzalo Ávila and Tito Claure from Bolivia, and Ricardo Sevilla from Peru. Finally, José Luis Zambrano, INIAP Ecuador, announced that the XXIIRLM will be held next year in Ecuador. The XXRLM was held last year in Lima, Peru.

The meeting was attended by representatives of national and international seed companies, NGOs, local governments, an agricultural bank, Bolivian universities such as Francisco Xavier University in Chuquisaca, Gabriel René Moreno de Santa Cruz University, Universidad Mayor de San Simón in Cochabamba, Peru’s La Molina National Agricultural University, national research centers such as INTA-Argentina, INIAF-Bolivia, EMBRAPA-Brazil, CORPOICA-Colombia, INIAP-Ecuador, INIA-Peru, and international research organizations such as IICA, JAICA from Japan, KOPIA from Korea, CIAT, and CIMMYT.
