For a number of reasons, including limited interdisciplinary collaboration and a dearth of funding, revolutionary new plant research findings are not being used to improve crops.

“Translational research” — efforts to convert basic research knowledge about plants into practical applications in crop improvement — represents a necessary link between the world of fundamental discovery and farmers’ fields. This kind of research is often seen as more complicated and time consuming than basic research and less sexy than working at the “cutting edge” where research is typically divorced from agricultural realities in order to achieve faster and cleaner results; however, modern tools — such as genomics, marker-assisted breeding, high throughput phenotyping of crop traits using drones, and speed breeding techniques — are making it both faster and cost-effective.

In a new article in Crop Breeding, Genetics, and Genomics, wheat physiologist Matthew Reynolds of the International Maize and Wheat Improvement Center (CIMMYT) and co-authors make the case for increasing not only funding for translational research, but the underlying prerequisites: international and interdisciplinary collaboration towards focused objectives and a visionary approach by funding organizations.

“It’s ironic,” said Reynolds. “Many breeding programs have invested in the exact technologies — such as phenomics, genomics and informatics — that can be powerful tools for translational research to make real improvements in yield and adaptation to climate, disease and pest stresses. But funding to integrate these tools in front-line breeding is quite scarce, so they aren’t reaching their potential value for crop improvement.”

Many research findings are tested for their implications for wheat improvement by the International Wheat Yield Partnership (IWYP) at the IWYP Hub, a centralized technical platform for evaluating innovations and building them into elite wheat varieties, co-managed by CIMMYT at its experimental station in Obregon, Mexico.

IWYP has its roots with the CGIAR Research Program on Wheat (WHEAT), which in 2010 formalized the need to boost both wheat yield potential as well as its adaptation to heat and drought stress. The network specializes in translational research, harnessing scientific findings from around the world to boost genetic gains in wheat, and capitalizing on the research and pre-breeding outputs of WHEAT and the testing networks of the International Wheat Improvement Network (IWIN). These efforts also led to the establishment of the Heat and Drought Wheat Improvement Consortium (HeDWIC).

“We’ve made extraordinary advances in understanding the genetic basis of important traits,“ said IWYP’s Richard Flavell, a co-author of the article. “But if they aren’t translated into crop production, their societal value is lost.”

The authors, all of whom have proven track records in both science and practical crop improvement, offer examples where exactly this combination of factors led to the impactful application of innovative research findings.

  • Improving the Vitamin A content of maize: A variety of maize with high Vitamin A content has the potential to reduce a deficiency that can cause blindness and a compromised immune system. This development happened as a result of many translational research efforts, including marker-assisted selection for a favorable allele, using DNA extracted from seed of numerous segregating breeding crosses prior to planting, and even findings from gerbil, piglet and chicken models — as well as long-term, community-based, placebo-controlled trials with children — that helped establish that Vitamin A maize is bioavailable and bioefficacious.
  • Flood-tolerant rice: Weather variability due to climate change effects is predicted to include both droughts and floods. Developing rice varieties that can withstand submergence in water due to flooding is an important outcome of translational research which has resulted in important gains for rice agriculture. In this case, the genetic trait for flood tolerance was recognized, but it took a long time to incorporate the trait into elite germplasm breeding programs. In fact, the development of flooding tolerant rice based on a specific SUB 1A allele took over 50 years at the International Rice Research Institute in the Philippines (1960–2010), together with expert molecular analyses by others. The translation program to achieve efficient incorporation into elite high yielding cultivars also required detailed research using molecular marker technologies that were not available at the time when trait introgression started.

Other successes include new approaches for improving the yield potential of spring wheat and the discovery of traits that increase the climate resilience of maize and sorghum.

One way researchers apply academic research to field impact is through phenotyping. Involving the use of cutting edge technologies and tools to measure detailed and hard to recognize plant traits, this area of research has undergone a revolution in the past decade, thanks to more affordable digital measuring tools such as cameras and sensors and more powerful and accessible computing power and accessibility.

Scientists are now able to identify at a detailed scale plant traits that show how efficiently a plant is using the sun’s radiation for growth, how deep its roots are growing to collect water, and more — helping breeders select the best lines to cross and develop.

Phenotyping is key to understanding the physiological and genetic bases of plant growth and adaptation and has wide application in crop improvement programs. Recording trait data through sophisticated non-invasive imaging, spectroscopy, image analysis, robotics, high-performance computing facilities and phenomics databases allows scientists to collect information about traits such as plant development, architecture, plant photosynthesis, growth or biomass productivity from hundreds to thousands of plants in a single day. This revolution was the subject of discussion at a 2016 gathering of more than 200 participants at the International Plant Phenotyping Symposium hosted by CIMMYT in Mexico and documented in a special issue of Plant Science.

There is currently an explosion in plant science. Scientists have uncovered the genetic basis of many traits, identified genetic markers to track them and developed ways to measure them in breeding programs. But most of these new findings and ideas have yet to be tested and used in breeding programs, wasting their potentially enormous societal value.

Establishing systems for generating and testing new hypotheses in agriculturally relevant systems must become a priority, Reynolds states in the article. However, for success, this will require interdisciplinary, and often international, collaboration to enable established breeding programs to retool. Most importantly, scientists and funding organizations alike must factor in the long-term benefits as well as the risks of not taking timely action. Translating a research finding into an improved crop that can save lives takes time and commitment. With these two prerequisites, basic plant research can and should positively impact food security.

Nepal’s seed sector partners join forces to realize the National Seed Vision 2013-2025

Access to affordable quality seed is one of the prerequisites to increase agricultural production and improve the livelihoods of Nepali farmers. However, there are significant challenges to boost Nepal’s seed industry and help sustainably feed a growing population.

Six years ago, Nepal launched its National Seed Vision 2013-2025. This strategic plan aims at fostering vibrant, resilient, market-oriented and inclusive seed systems in public-private partnership modalities, to boost crop productivity and enhance food security.

The Nepal Seed and Fertilizer (NSAF) project, led by the International Maize and Wheat Improvement Center (CIMMYT), is supporting the government to enhance national policies and guidelines, and private seed companies to build competitive seed businesses and hybrid seed production.

Quality seed can increase crop yield by 15-20%. However, there are critical challenges hindering the growth of Nepal’s seed industry. Existing seed replacement rate for major cereals is low, around 15%. About 85% of Nepali farmers are unable to access recently developed improved seeds — instead, they are cultivating decades-old varieties with low yield and low profits. Some of the factors limiting the development of seed systems are the high cost of seed production and processing, the limited reach of mechanization, and the low use of conservation agriculture practices.

The demand for hybrid seeds in Nepal is soaring but research in variety development is limited. Most of the country’s supply comes from imports.

In collaboration with the Nepal Agricultural Research Council (NARC), the NSAF project team is working with seed companies and cooperatives to scale hybrid seed production of maize, tomato and rice. Through this project, CIMMYT collaborated with the Seed Quality Control Center (SQCC) and national commodity programs of the NARC to draft the first hybrid seed production and certification guidelines for Nepal to help private seed companies produce and maintain standards of hybrid seeds.

Extension and promotion activities are essential to bring improved seed varieties to farmers. Standard labelling and packaging also needs to be strengthened.

A joint effort

CIMMYT and its partners organized a two-day workshop to review the progress of the National Seed Vision. The event attracted 111 participants from government institutions, private companies and development organizations engaged in crop variety development, seed research, seed production and dissemination activities.

In the opening remarks, Yubak Dhoj G.C., Secretary of Nepal’s Ministry of Agriculture and Livestock Development, addressed the seed sector scenario and its challenges. He stressed the importance of collaboration among seed stakeholders to meet the targets of the National Seed Vision in the next six years.

During the technical sessions, Madan Thapa, Chief of the SQCC, analyzed the current status of the National Seed Vision and highlighted the challenges as well as the opportunities to realize it.

Laxmi Kant Dhakal, Chairperson of the Seed Entrepreneurs Association of Nepal (SEAN) emphasized the importance of private sector engagement and other support areas to strengthen seed production and marketing of open-pollinated varieties and hybrids.

Tara Bahadur Ghimire, Principal Scientist at NARC, gave an overview of the status of NARC varieties, source seed and resource allocation.

Dila Ram Bhandari, former Chief of SQCC, led a discussion around the assumptions and expectations that arose while developing the National Seed Vision.

Technical leads of maize, rice, wheat and vegetables presented a road map on hybrid variety development and seed production in line with the National Seed Vision’s targets for each crop.

“A large quantity of hybrid seeds, worth millions of dollars, is being imported into Nepal each year,” explained AbduRahman Beshir, Seed Systems Lead of CIMMYT’s NSAF project. “However, if stakeholders work together and strengthen the local seed system, there is a huge potential in Nepal not only to become self-sufficient but also to export good quality hybrid seeds in the foreseeable future. Under the NSAF project we are witnessing a few seed companies that have initiated hybrid seed production of maize and tomato.”

In one of the exercises, workshop participants were divided in groups and examined different topics related to the realization of the National Seed Vision. They looked at genetic resources, hybrid and open-pollinated variety development, source seed production and supply, private sector engagement and marketing, seed extension and varietal adoption by farmers, seed quality control services, and roles of research partners and other stakeholders. The groups presented some of the major challenges and opportunities related to these topics, as well as recommendations, which will be documented and shared.

The outcomes of this mid-term review workshop will inform policy and guide the discussions at the upcoming International Seed Conference to be held in early September 2019.

Regulating hybrid seed production

At the workshop, participants thoroughly discussed the draft hybrid seed production and certification guidelines, developed under the NSAF project.

The guidelines are the first of their kind in Nepal and essential to achieve the targets of the National Seed Vision, by engaging the private sector in hybrid seed production.

Hari Kumar Shrestha, CIMMYT’s Seed Systems Officer, and other seed experts from the SQCC presented the main features and regulatory implications of the guidelines.

After the workshop, the guidelines were sent to the National Seed Board for approval.

Climate Services for Resilient Development in South Asia (CSRD)

Climate Services for Resilient Development (CSRD) is a global partnership that connects climate and environmental science with data streams to generate decision support tools and training for decision-makers in developing countries. Translating complex climate information into easy to understand actionable formats to spread awareness in the form of climate services is core to CSRD’s mission. CSRD works across South Asia (with emphasis on Bangladesh), the Horn of Africa (Ethiopia), and in South America (Colombia) to generate and provide timely and useful climate information, decision tools and services. In South Asia, CSRD focusses the development, supply and adaptation of agricultural climate services to reduce vulnerability by increasing resiliency in smallholder farming systems. These goals are strategically aligned with the Global Framework for Climate Services.

Project description

CSRD in South Asia aims to have the impact by increasing climate resilient farm management, indicated by increased use of climate services and climate information to inform farmers on how to better manage their production systems.  CSRD also aims to develop and validate models for agricultural climate services that can be replicated in other regions with similar farming systems and climate risks, while also fine-tuning weather and climate advisories to be most useful to farmers’ decision-making. A series of sustained contributions to CSRD’s Action and Learning Framework Pillars 1-4, detailed below, are envisioned as major project outcomes:

  • Pillar 1: Create the solution space:
    CSRD works to establish a problem-focus, to engage key stakeholders, to create a platform for sustained communication and collaboration, and to build synergies among relevant programs.
  • Pillar 2: Utilize quality data, products, and tools
    CSRD provides access to useful and available information and technology, and to develop tailored products and services responsive to problem-specific needs.
  • Pillar 3: Build capacities and platforms
    CSRD supports the use of targeted products and services, and to promote sustainability, scalability, and replicability.
  • Pillar 4: Build knowledge
    A key goal of CSRD’s work is to identify and promote good practices among the global climate services community and to support research efforts and innovation that increase the effectiveness of climate services.

Outputs

CSRD in South Asia will ultimately generate the following broad outputs and services:

New drought monitoring system will reduce climate risks for South Asian farmers

To mitigate the food security and economic risks of South Asia’s frequent and intense droughts, scientists and policymakers from the South Asian Association for Regional Cooperation (SAARC), the International Centre for Integrated Mountain Development (ICIMOD) and the International Maize and Wheat Improvement Center (CIMMYT) recently joined forces to launch an innovative decision support and agricultural planning system that combines remote sensing and  climate data analysis for drought monitoring and early warning.

The Regional Drought Monitoring and Outlook System application was unveiled during a workshop to train experts and policymakers in its use at relevant regional and national institutes in Islamabad, Pakistan, from July 29 to August 1, 2019. The Regional Drought Monitoring and Outlook System is the product of an ICIMOD-CIMMYT partnership through the United States Agency for International Development (USAID) and the National Aeronautics and Space Administration (NASA) supported SERVIR Hindu Kush Himalaya (HKH) programme, in collaboration with Climate Service for Resilient Development (CSRD), led by ICIMOD and CIMMYT, respectively.

“Commonly associated with epic flooding, particularly in the enormous breadbasket region known as the Indo-Gangetic Plains that extends across Pakistan, India, southern Nepal, and Bangladesh, the region also faces droughts driven by rising temperatures and erratic rainfall and which threaten crops, food security, and livelihoods,” said Faisal Mueen Qamer, Remote Sensing Specialist of ICIMOD, which helped develop the system and organize the workshop.

“We expect the system to foster resilience in South Asian agriculture, while supporting future institutional frameworks and policies for farm compensation and adaptation, through decision makers’ access to timely and action-oriented information,” Qamar explained.

With a growing population of 1.6 billion people, South Asia hosts 40% of the world’s poor and malnourished on just 2.4% of its land. A 2010 study found a linear drop of 7.5% in rainfall in South Asia from 1900 to 2005.

“Shrinking glaciers, water scarcity, rising sea levels, shifting monsoon patterns, and heat waves place considerable stress on South Asian countries, whose primary employment sector remains agriculture,” said Mohammad Faisal, Director General for South Asia at Pakistan’s Ministry of Foreign Affairs, during the workshop opening.

Media reports in early 2019 documented displacement and hunger from Pakistan’s worst drought in years.

Raising awareness about drought and its mitigation

Twenty-three participants from six South Asia countries plus five expert instructors attended the workshop, which offered presentations and hands-on training on a suite of applications and associated data analysis tools, including the South Asian Land Data Assimilation System (SALDAS), the Regional Drought Explorer, and the National Drought Early Warning System.

Muhammad Azeem Khan, Member of the Food Security & Climate Change at the Planning Commission of Pakistan, said the scale of present and future climate challenges is clearly evident.

“In Pakistan, we regularly see parts of the country in the grip of severe drought, while others have flash floods,” Khan commented during the workshop closing, while commending its organizers. “Frequent drought diminishes agricultural production and food security, especially for people in rural areas. Effectively managing the impacts of climate change requires a response that builds and sustains South Asia’s social, economic, and environmental resilience, as well as our emergency response capacity.”

Through CSRD, a global partnership that connects climate and environmental science with data streams to generate decision support tools and training for decision-makers in developing countries, CIMMYT helped extend the Regional Drought Monitoring and Outlook System to Bangladesh, from its original coverage of Afghanistan, Nepal, and Pakistan.

“Translating complex climate information into easy-to-understand and actionable formats is core to CSRD’s mission and helps spread awareness about climate challenges,” said Tim Krupnik, CIMMYT cropping systems agronomist based in Bangladesh. “This consortium provides strength and technical expertise to develop relevant climate products, including decision-support information for farmers and other stakeholders, thus fostering resilience to climate-related risks.”

New publications: A study of water markets in Bangladesh

Domestic rice and wheat production in Bangladesh has more than doubled in the last 30 years, despite declining per capita arable land. The fact that the country is now almost self-sufficient in staple food production is due in large part to successful and rapid adoption of modern, high-yielding crop varieties. This has been widely documented, but less attention has been paid to the contribution of small-scale irrigation systems, whose proliferation has enabled double rice cropping and a competitive market system in which farmers can purchase irrigation services from private pump owners at affordable rates.

However, excess groundwater abstraction in areas of high shallow tube-well density and increased fuel costs for pumping have called into question the sustainability of Bangladesh’s groundwater irrigation economy. Cost-saving agronomic methods are called for, alongside aligned policies, markets, and farmers’ incentives.

A recent study by researchers at the International Maize and Wheat Improvement Center (CIMMYT) examines the different institutions and water-pricing methods for irrigation services that have emerged in Bangladesh, each of which varies in their incentive structure for water conservation, and the level of economic risk involved for farmers and service providers.

Using primary data collected from 139 irrigation service providers and 556 client-farmers, the authors assessed the structure of irrigation service types as well as the associated market and institutional dimensions. They found that competition between pump owners, social capital, and social relationship between of pump owners and client farmers, significantly influence the structure of irrigation services and irrigation water pricing methods. Greater competition between pump owners, for instance, increases the likelihood of pay-per-hour services while reducing that of crop sharing arrangements.

Based on these and other findings, authors made policy recommendations for enhancing irrigation services and sustainability in Bangladesh. As Bangladesh is already highly successful in terms of the conventional irrigation system, the authors urge taking it to the next level for sustainability and efficiency.

Currently Bangladesh’s irrigation system is based on centrifugal pumps and diesel engines. The authors suggest scaling out the energy efficient axial flow pump, and the alternate wetting and drying system for water conservation and irrigation efficiency. They also recommend further investment in rural electrification to facilitate the use of electric motors, which can reduce air pollution by curbing dependency on diesel engines.

Precision spreader for fertilizer set to change the agriculture scene in Nepal

Smallholder farmers in Nepal tend to apply fertilizer by hand, spreading it as they walk through the field. Under this practice, fertilizer is dispersed randomly and is therefore unevenly distributed among all the seedlings. A recently introduced method, however, helps farmers spread fertilizer in a more uniform, faster and easier way.

The precision spreader is a hand-operated device that ensures an even distribution of fertilizer and is easy to operate. This technology is endorsed by the Cereal Systems Initiative for South Asia (CSISA), a project led by the International Maize and Wheat Improvement Center (CIMMYT) which helps Nepalese farmers adapt measures that are efficient, effective and resilient to the impacts of climate change.

In addition to more consistent distribution, the precision spreader regulates the exact amount of fertilizer required and helps the farmer cover a considerable area with limited movement. This technology has been proven to require less time and effort than the traditional method of broadcasting by hand.

Considering the potential benefits, the CSISA team introduced farmers in Nepal to the precision spreader through training sessions followed by demonstrations of its use. They took place in wheat fields in Bansgadhi, Barbardiya and Duduwa, in Lumbini province, in collaboration with multipurpose cooperative Janaekata and the local governments. Through these sessions, conducted in 45 different sites, more than 650 farmers had a chance to familiarize themselves with the precision spreader, and most of them took a keen interest in incorporating the device into their cropping management practices.

Perhaps the most prominent reason why the precision spreader sparked such interest is that women can easily use it. Most men in rural areas have migrated to the city or abroad in hopes of higher income, so work in the fields has been inadvertently transferred to women. Since Nepal is a predominantly conservative patriarchal society, women have not yet become comfortable and familiarized with all farming practices, especially operating heavy agricultural machinery. However, as expressed by women themselves, the precision spreader is highly convenient to use. Its use could help ease women into the agriculture scene of Nepal and consequently reduce farming drudgery.

Healthier crops, healthier people

Nestled between China and India, Nepal predominantly relies on agriculture for employment. With the majority of its population engaged in the agricultural sector, the country still struggles to produce an adequate food supply for its people, resulting in depressed rural economies, increased malnutrition and widespread hunger.

Sustainable intensification, therefore, is necessary to increase the overall yield and to accelerate agricultural development.

Better distribution of fertilizer in the fields results in a higher chance of healthier crops, which are the source of better nutrition.

A wider use of a seemingly small technology like the precision spreader would not only reduce hardships in farming, but it would also help farmers become more resilient towards the natural and economic adversities they face.

The Cereal Systems Initiative for South Asia (CSISA) is a regional project in Bangladesh, India and Nepal that was established in 2009 with the goal of benefiting more than 8 million farmers by the end of 2020. Funded by the United States Agency for International Development (USAID) and the Bill & Melinda Gates Foundation, CSISA is led by the International Maize and Wheat Improvement Center (CIMMYT) and implemented jointly with the International Food Policy Research Institute (IFPRI) and the International Rice Research Institute (IRRI).

What farmers want

Tabitha Kamau, 29, is scrutinizing a maize demonstration plot on which 12 different varieties were planted in November 2018. “What I am looking for is a maize variety that produces a lot, even when there is scarce rainfall,” says the single mother of three, who lives in Katheini, in Kenya’s Machakos County, on a quarter of an acre of land.

Together with 350 other smallholder farmers from Katheini and neighboring villages, Kamau is assessing the maize crops and ranking them based on her preferred traits.

Like her peers when asked what makes a good maize variety, she gives high scores to drought-tolerant varieties and those that can yield large and nicely filled cobs despite the dry spell that has affected the area over the last two months.

For five years, Kamau has been planting KDV4, a drought-tolerant open pollinated variety on the family land and another piece of leased plot. This early variety matures in 100 to 110 days and is adapted to dry mid-altitude conditions.

KDV4 was released by the Kenya Agricultural & Livestock Research Organization (KALRO) using the International Maize and Wheat Improvement Center (CIMMYT)’s germplasm. It is currently marketed by Dryland Seed Limited and Freshco Seeds, targeting farmers in the water-stressed counties of Kitui, Machakos and Makueni, in the lower eastern regions of Kenya.

The early maturing of varieties like KDV4 presents a good opportunity for its adopters, says Kamau. “If I am able to harvest in three and a half months or less, compared to four months or more for other varieties, I can sell some grain to neighbors still awaiting their harvest who want to feed their families.”

“I heard of new varieties that can germinate well and produce lots of leaves,” explains Catherine Musembi. This farmer from Kivaani looks for maize that performs well even under heat and drought. She likes maize plants with high biomass, as the foliage is used to feed the family’s three cows and two goats.

Farmers’ picks

The International Maize and Wheat Improvement Center (CIMMYT) has been undertaking participatory maize variety evaluations since 2016 in Kenya, Rwanda, Tanzania and Uganda. Every year, during the main maize growing season, researchers plant on-farm trials that can be evaluated by farmers.

Kamau and Musembi attended a selection trial in Machakos County, facilitated by a team from KALRO on February 18-19, 2019. This exercise was part of the 2018 mid-season evaluations, which were followed up by end-season assessments a month later.

Participatory farmer evaluations are used to give crucial feedback to CIMMYT’s maize breeding work. First, farmers get an opportunity to state what traits are important for them and rank them according to their importance. Then, participants evaluate varieties planted in the trial and give a score on individual trait and the overall performance for each variety planted. And they conclude the exercise by rating the best three plots.

In the drier eastern part of Kenya, farmers might be more interested in traits such as drought tolerance, early maturity and disease resistance. In central Kenya, where dairy farming is commonly practiced, a variety with more biomass could be preferred.

“Our work is to tease out the information regarding which traits contribute to a good score in the overall score,” explains Bernard Munyua, a socioeconomics research assistant at CIMMYT. Statistical analysis of the farmers’ score cards will reveal if the initial rating of criteria plays a strong role in the final overall appreciation of a variety. For instance, farmers may give high importance to height or biomass, yet it may not play a role in their ranking of best varieties.

“Such data is important for maize breeders to support future variety improvement work,” Munyua notes. “Moreover, by disaggregating the farmers opinions by region and socioeconomic attributes such as gender, education and income, we can define the priority traits by region or farmers’ socioeconomic profiles. It helps better target maize breeding work according to the needs on the ground and gives useful knowledge to seed companies for their seed marketing strategy,” he adds.

For instance, in the drier eastern part of Kenya, farmers might be more interested in traits such as drought tolerance, early maturity and disease resistance. In central Kenya, where dairy farming is commonly practiced, a variety with more biomass could be preferred. In western Kenya, they could be more interested in grain yields and cob characteristics to improve their sales after harvest.

Agnes Nthambi, the farmer who hosted the demonstration plot, is very positive about her participation, as she learned about some of the ideal agronomic practices as well as the performance of new varieties. “On this trial, I learned that spacing was about two times shorter than we are generally used to. Even with the more constricted spacing, the maize has performed much better than what we are used to seeing,” she says. She also learned that fertilizer is applied at the time of planting. In her case, she normally applies fertilizer much later after germination has already occurred.

Nthambi says her family cannot afford losing both the fertilizer and the seed in case the rains fail. This time, she expects a good harvest from the one-acre farm, to supplement her family’s income.

Improved access to finance can boost seed business in Nepal

Finance is a key driver for agricultural development, as it allows farmers and agribusinesses to improve production efficiency and adopt improved technologies. In Nepal, most of the seed in the formal sector is produced by companies and cooperatives which, like any enterprise, need access to finance in order to grow and increase their capacity.

Nepal’s Agricultural Development Strategy 2015-2035 and National Seed Vision 2013-2025 are key policy documents of the government that provide a roadmap for the development of the agricultural and seed sectors in the country.

In 2017, realizing the need to increase investments in the agricultural sector, the central bank of Nepal, Nepal Rastra Bank, adopted the Priority Sector Lending Programme (PSLP). This program mandates banks and financial institutions to allocate 10% of their loan portfolio to the agricultural sector at a subsidized interest rate of 5%.

The Nepal Seed and Fertilizer (NSAF) project is providing an interface between banks and seed enterprises. Commercial banks are improving their knowledge of the seed sector, its needs and growth opportunities, so they can develop loan products and credit modalities that match the requirements of seed producers and agribusinesses.

These enterprises require finances to upgrade their infrastructure, increase production and grow their businesses. The business plans of seed companies which partner with the NSAF project indicate that the average size of loan required is around $50,000 — 60% for infrastructure development and 40% for working capital. About 66% of the working capital is used to procure raw seed from contract seed growers.

Barriers to lending

Given the huge requirement for finance for seed procurement, access to loans through the PSLP can provide respite to seed companies. However, unlike in other commercial agribusiness, bank lending under the PSLP is uncommon in the seed business, as financial institutions lack understanding of the sector. Many seed companies have not been able to benefit from these loans due to perceived high risks or the lack of business plans and compliance mechanisms required by banks.

In 2018, the NSAF project team assessed the current status, challenges and opportunities in seed business financing through the PSLP. The project also facilitated a seed growers’ lending model through a tripartite agreement between Laxmi Bank Pvt. Limited, Panchashakti Seed Company and seed growers to access loans under PSLP.

On June 14, 2019, NSAF organized a meeting in collaboration with Seed Entrepreneurs Association of Nepal (SEAN) to present findings of their assessments and experiences. The meeting brought together representatives from the Ministry of Agriculture and Livestock Development, national financial institutions, private sector banks, seed companies, agricultural cooperatives and development organizations, who took part in the deliberations and also contributed to refining policy recommendations to enhance seed sector financing.

The assessments showed that PSLP awareness among farmers is low and seed growers borrowing from the informal sector were paying high interest rates, ranging from 24-36% per year. Lack of adequate business plans and compliance mechanisms for seed companies, limited eligibility criteria for PSLP, complex loan acquisition process and collateral issues were some of the factors that made funds largely inaccessible to smallholder farmers. Moreover, the terms and conditions for loan repayment stipulated by banks do not synchronize with the agricultural crop calendar and farm cash flows.

Tailor-made financing solutions

Participants in the meeting discussed ways to create a conducive environment to access financial services for agricultural producers and agribusinesses. Seed companies suggested to improve banks and financial institutions’ understanding of the agricultural markets and build their capacity to assess business opportunities. They also requested that banks simplify the documentation process for acquiring loans for farmers.

Participants from the Kisanka Lagi Unnat Biu-Bijan Karyakram (KUBK), a Nepal government project located in Rupandehi district Province 5, highlighted their model where farmers, organized into cooperatives, are linked to the Small Farmer Development Bank, which could be worth exploring in other sites.

Branchless banking promoted by NSAF is a workable strategy to provide financial services to seed growers in remote areas.

The action research also highlighted that innovative modalities, such as group guarantees, can be a feasible approach to mitigate risks to fund seed growers who do not have land registration certificates and whose land rights have not been transferred in their names. In the case of female producers, this is especially helpful, as many women are the lead decision-makers on the land registered under the name of their husbands, who are migrant workers abroad.

Utilizing the learning from this event, NSAF and SEAN will share the evidence-based policy recommendations with the Ministry of Agriculture and Livestock Development, the Ministry of Finance, the central bank and the Bankers’ Association of Nepal.

Through the NSAF project’s facilitation, banks have approved loans amounting to $2.5 million for business expansion of seven seed companies in 2018. The project will continue to support its seed partners in developing and strengthening their business plans and will facilitate linkages with commercial banks.

The Nepal Seed and Fertilizer project is funded by the United States Agency for International Development (USAID) and is a flagship project in Nepal. The objective of NSAF is to build competitive and synergistic seed and fertilizer systems for inclusive and sustainable growth in agricultural productivity, business development and income generation in Nepal.

Cranking, a thing of the past

Halima Begum wanted to increase her income by providing mechanization services to other farmers in Bangladesh’s Chuadanga district, but she was limited by the level of physical effort required. Starting the engine of her tractor was difficult and embarrassing — cranking it required a lot of strength and she had to rely on others to do it for her. She was also afraid she would get injured, like other local service providers.

Women in rural areas of Bangladesh are often hesitant to work in the fields. Social norms, limited mobility, physical exertion, lack of time and other constraints can cause aspiring female entrepreneurs to step back, despite the prospect of higher income. The few women like Halima who do step out of their comfort zone and follow their dreams often have to overcome the physical effort required to operate these machines.

Starting the tractor is a daunting task on its own and the possibility of having to do it multiple times a day adds to the reluctance of ownership.

To make manual cranking a thing of the past for Bangladeshi women entrepreneurs, and to encourage others, the International Maize and Wheat Improvement Center (CIMMYT), through the Cereal Systems Initiative for South Asia-Mechanization and Irrigation (CSISA-MI), is supporting small businesses who manufacture and sell affordable mechanical self-starter attachments for two-wheel tractors.

The self-starter is a simple spring-loaded device mounted over the old crank handle socket, which allows users to start the engine with the flick of a lever.

For women like Begum, manually starting a tractor was a difficult task that is now gone forever.

“I used to struggle quite a lot before, but now I can easily start the machine, thanks to this highly convenient self-starter,” Begum said.

The self-starter reduces the risk of accidents and coaxes hesitant youth and women to become entrepreneurs in the agricultural mechanization service industry.

CIMMYT is supporting businesses like Janata Engineering, which imports self-starter devices and markets them among local service providers in the district of Sorojgonj, Chuadanga district. The project team worked with the owner, Md. Ole Ullah, to organize field demonstrations for local service providers, showing how to use and maintain the self-starter device.

The Cereal Systems Initiative for South Asia-Mechanization and Irrigation (CSISA-MI) is led by the International Maize and Wheat Improvement Center (CIMMYT) and funded by the United States Agency for International Development (USAID). The project focuses on upstream market interventions in Bangladesh, ensuring technologies are reliably available in local markets and supported by an extensive value chain.

Ethiopian farmers weatherproof their livelihoods

Many maize farmers in sub-Saharan Africa grow old varieties that do not cope well under drought conditions. In the Oromia region of Ethiopia, farmer Sequare Regassa is improving her family’s life by growing the newer drought-tolerant maize variety BH661. This hybrid was developed by the Ethiopian Institute of Agricultural Research (EIAR), using CIMMYT’s drought-tolerant inbred lines and one of EIAR’s lines. It was then officially released in 2011 by the EIAR as part of the Drought Tolerant Maize for Africa (DTMA) project, funded by the Bill & Melinda Gates Foundation and continued under the Stress Tolerant Maize for Africa (STMA) initiative.

“Getting a good maize harvest every year, even when it does not rain much, is important for my family’s welfare,” said Regassa, a widow and mother of four, while feeding her granddaughter with white injera, a flat spongy bread made of white grain maize.

Since her husband died, Regassa has been the only breadwinner. Her children have grown up and established their own families, but the whole extended family makes a living from their eight-hectare farm in Guba Sayo district.

On the two hectares Regassa cultivates on her own, she rotates maize with pepper, sweet potato and anchote, a local tuber similar to cassava. Like many farming families in the region, she grows maize mainly for household food consumption, prepared as bread, soup, porridge and snacks.

Maize represents a third of cereals grown in Ethiopia. It is cheaper than wheat or teff — a traditional millet grain — and in poor households it can be mixed with teff to make the national staple, injera.

In April, as Regassa was preparing the land for the next cropping season, she wondered if rains would be good this year, as the rainy season was coming later than usual.

In this situation, choice of maize variety is crucial.

She used to plant a late-maturing hybrid released more than 25 years ago, BH660, the most popular variety in the early 2000s. However, this variety was not selected for drought tolerance. Ethiopian farmers face increasing drought risks which severely impact crop production, like the 2015 El Nino dry spell, leading to food insecurity and grain price volatility.

Laborious development for fast-track adoption

Under the DTMA project, maize breeders from CIMMYT and the Ethiopian Institute for Agricultural Research (EIAR) developed promising drought-tolerant hybrids which perform well under drought and normal conditions. After a series of evaluations, BH661 emerged as the best candidate with 10% better on-farm grain yield, higher biomass production, shorter maturity and 34% reduction in lodging, compared to BH660.

The resulting BH661 variety was released in 2011 for commercial cultivation in the mid-altitude sub-humid and transition highlands.

The year after, as farmers experienced drought, the Ethiopian extension service organized BH661 on-farm demonstrations, while breeders from CIMMYT and EIAR organized participatory varietal selection trials. Farmers were impressed by the outstanding performances of BH661 during these demos and trials and asked for seeds right away.

Seed companies had to quickly scale up certified seed production of BH661. The STMA project team assisted local seed companies in this process, through trainings and varietal trials. Companies decided to replace the old hybrid, BH660.

“In addition to drought tolerance, BH661 is more resistant to important maize diseases like Turcicum leaf blight and grey leaf spot,” explained Dagne Wegary, a maize breeder at CIMMYT. “For seed companies, there is no change in the way the hybrid is produced compared to BH660, but seed production of BH661 is much more cost-effective.”

EIAR’s Bako National Maize Research Center supplied breeder seeds to several certified seed producers: Amhara Seed Enterprise (ASE), Bako Agricultural Research Center (BARC), Ethiopian Seed Enterprise (ESE), Oromia Seed Enterprise (OSE) and South Seed Enterprise (SSE). Certified seeds were then distributed through seed companies, agricultural offices and non-governmental organizations, with the technical and extension support of research centers.

From drought risk to clean water

After witnessing the performance of BH661 in a neighbor’s field, Regassa asked advice from her local extension officer and decided to use it. She is now able to produce between 11-12 tons per hectare. She said her family life has changed forever since she started planting BH661.

With higher maize grain harvest, she is now able to better feed her chickens, sheep and cattle. She also sells some surplus at the local market and uses the income for her family’s needs.

“If farmers follow the recommended fertilizer application and other farming practices, BH661 performs much better than the old BH660 variety,” explained Regassa. “If we experience a drought, it may be not that bad thanks to BH661’s drought tolerance.”

Regassa buys her improved seeds from the Bako Research Station, as well as from farmers’ cooperative unions. These cooperatives access seeds from seed companies and sell to farmers in their respective districts. “Many around me are interested in growing BH661. Sometimes we may get less seeds than requested as the demand exceeds the supply,” Regassa said.

She observed that maize prices have increased in recent years. A 100 kg bag of maize that used to sell for 200–400 Ethiopian birr (about $7–14) now sells for 600–700 Ethiopian birr (about $20–23). With the increased farmers’ wealth in her village, families were able to pay collectively for the installation of a communal water point to get easy access to clean water.

“Like women’s role in society, no one can forget the role maize has in our community. It feeds us, it feeds our animals, and cobs are used as fuel. A successful maize harvest every year is a boon for our village,” Regassa concluded.

Seeds of progress

 

The maize seed sector in east and southern Africa is male-dominated. However, there are women working in this sector who are breaking social barriers and helping to improve household food security, nutrition and livelihoods by providing jobs and improved seed varieties to farmers.

Researchers from the International Maize and Wheat Improvement Center (CIMMYT) conducted interviews with women owners of seed companies in eastern and southern Africa. They shared information on their background, their motivation to start their businesses, what sets their companies apart from the competition, the innovative approaches they use to ensure smallholder farmers adopt improved seed varieties, the unique challenges they face as women in the seed sector and the potential for growth of their companies.

Research, innovation, partnerships, impact

On May 15, 2019, as part of the CGIAR System Council meeting held at the ILRI campus in Addis Ababa, Ethiopia, around 200 Ethiopian and international research and development stakeholders convened for the CGIAR Agriculture Research for Development Knowledge Share Fair. This exhibition offered a rare opportunity to bring the country’s major development investors together to learn and exchange about how CGIAR investments in Ethiopia help farmers and food systems be more productive, sustainable, climate resilient, nutritious, and inclusive.

Under the title One CGIAR — greater than the sum of its parts — the event offered the opportunity to highlight close partnerships between CGIAR centers, the Ethiopian government and key partners including private companies, civil society organizations and funding partners. The fair was organized around the five global challenges from CGIAR’s business plan: planetary boundaries, sustaining food availability, promoting equality of opportunity, securing public health, and creating jobs and growth. CGIAR and its partners exhibited collaborative work documenting the successes and lessons in working through an integrated approach.

There were 36 displays in total, 5 of which were presented by CIMMYT team members. Below are the five posters presented.

How can the data revolution help deliver better agronomy to African smallholder farmers?

This sustainability display showed scalable approaches and tools to generate site-specific agronomic advice, developed through the Taking Maize Agronomy to Scale in Africa (TAMASA) project in Nigeria, Tanzania and Ethiopia.

This poster describes how CGIAR works with Ethiopia’s research & development sector to support national food security priorities.

Addressing gender norms in Ethiopia’s wheat sector

Research shows that restrictive gender norms prevent women’s ability to innovate and become productive. This significantly impacts Ethiopia’s economy (over 1% GDP) and family welfare and food security.

Quality Protein Maize (QPM) for better nutrition in Ethiopia

With the financial support of the government of Canada, CIMMYT together with national partners tested and validated Quality Protein Maize as an alternative to protein intake among poor consumers.

Appropriate small-scale mechanization

The introduction of small-scale mechanization into the Ethiopian agriculture sector has the potential to create thousands of jobs in machinery service provision along the farming value chain.

System uses plants to lure fall armyworm away from maize fields

Push-pull cropping system in maize. (Figure: CIMMYT)
Push-pull cropping system in maize. (Figure: CIMMYT)

Climate conditions in Nepal are suitable for the establishment of fall armyworm, which could cause considerable crop loss if not managed properly. The fall armyworm is a destructive pest that has a voracious appetite for maize and other crops. Through the Nepal Seed and Fertilizer (NSAF) project, the International Maize and Wheat Improvement Center (CIMMYT) is working with the government of Nepal and other partners to address this imminent threat.

Chemical control of fall armyworm is too expensive and impractical for small-scale farmers, has negative human health effects, and can be a source of soil pollutants with a negative effect on biodiversity.

CIMMYT is currently evaluating the efficacy of push-pull cropping systems to control fall armyworm. Considered one of the most climate-smart technologies, push-pull systems use plant-pest ecology instead of harmful chemical insecticides to control weeds and insects. It is an environmentally friendly pest control method which is also economically viable for maize producers.

This system involves two types of crops: Napier grass (Pennisetum purpureum) and silverleaf desmodium legume (Desmodium uncinatum).

Desmodium plants are intercropped with the rows of maize and Napier grass surrounds the maize crop. Desmodium produces volatile chemicals that repel fall armyworm moths, while the Napier grass produces chemicals that attract female moths. The resulting push-pull system takes the pest away from the maize field.

An additional benefit is that desmodium improves nitrogen fertility through biological nitrogen fixation, which may reduce nitrogen input in the long-term. Desmodium also provides ground cover for maize, controlling soil erosion and offering protection from extreme heat conditions. Both desmodium and Napier grass are excellent fodder crops for livestock.

Because of all these reasons, push-pull technology is highly beneficial to smallholders who are dependent on locally available inputs for their subsistence farming. It can also have a positive spiral effect on the environment.

Scientists in other regions are also looking at agro-ecological options to manage fall armyworm.

A burning issue

Pollution has become a part of our daily life: particulate matter in the air we breathe, organic pollutants and heavy metals in our food supply and drinking water. All of these pollutants affect the quality of human life and create enormous human costs.

India is home to 15 of the world’s cities with the highest air pollution, making it a matter of national concern. The country is the world’s third largest greenhouse gas emitter, where agriculture is responsible for 18% of total national emissions.

For decades, CIMMYT has engaged in the development and promotion of technologies to reduce our environmental footprint and conserve natural resources to help improve farmer’s productivity.

Efficient use of nitrogen fertilizers, better management of water, zero-tillage farming, and better residue management strategies offer viable solutions to beat air pollution originating from the agriculture sector. Mitigation measures have been developed, field tested, and widely adopted by farmers across Bangladesh, India, Nepal and Pakistan.

“Multi-lateral impacts of air pollution link directly it to various sustainability issues,” explained Balwinder Singh, Cropping Systems Simulation Modeler at CIMMYT. “The major sustainability issues regarding air quality revolve around the common question: How good is good enough to be sustainable? We need to decide how to balance the sustainable agriculture productivity and hazardous pollution levels. We need to have policies on the regulation of crop burning and in addition to policies surrounding methods to help reach appropriate air quality levels.”
