Zambia officials promote sustainable maize cropping practices for small-scale farmers

Written by Mike Listman on November 8, 2022. Posted in Features.

For the first time in Zambia, a special Ministry of Agriculture committee has endorsed innovative sustainable intensification practices to diversify maize-based farming systems and boost the food and nutritional security of millions of small farm households, while enriching depleted soils.

Zambia’s recently formed “National Advisory Committee for the Approval/Validation of Candidate Technologies or Agronomic Practices” approved in September the release to farmers of three new systems for better yields and soil maintenance: growing maize between “hedge-rows” of legume trees; or in rows side-by-side with grain legumes as strip crops; or on permanent, raised soil beds or ridges.

Legume trees and grain legumes enhance soil nitrogen and organic matter content, and legume grains themselves are a valuable, alternative food, rich in protein for rural households. Raised soil beds and ridges can keep soils oxygenated and productive when heavy rainfall floods the fields, as can often occur in northern and northwestern Zambia.

All three systems can be bundled with conservation agriculture approaches, which are based on the principles of minimum soil disturbance, keeping crop residues on the soil, and growing a more diverse selection of crops.

The improved maize cropping methods are a research outcome of the Sustainable Intensification of Smallholder Farming Systems in Zambia (SIFAZ) project, a partnership involving the Food and Agriculture Organization (FAO) of the United Nations, Zambia’s Ministry of Agriculture (MoA), and the International Maize and Wheat Improvement Centre (CIMMYT), with funding from the European Union (EU) and building in part on other results in Africa, including the Feed the Future-Africa Research in Sustainable Development for the Next Generation (Africa RISING) initiative.

“The official clearing of these transformative cropping technologies is a huge milestone for the project and for Zambia’s resource-poor farmers,” said Christian Thierfelder, CIMMYT principal cropping systems agronomist based in southern Africa who, as part of SIFAZ, is testing and disseminating maize cropping practices that boost harvests, enrich soils, and capture and conserve moisture. “We’re working closely with Zambia’s MoA and the FAO, planning research trials, demonstrations and promotion to reach 20,000 farmers as a first step.”

An essential crop

Maize is the number-one food staple in sub-Saharan Africa, sown by some 300 million smallholder farmers using seasonal rains. A leading crop as well for Zambia’s small-scale, subsistence, and often impoverished farmers, maize grows poorly in extreme heat, infertile soils, and extended dry weather. Failed maize crops can bring hunger to smallholders and their families, for whom risks are high and formal safety nets are non-existent.

The EU recently announced that it will provide an additional EUR 20 million in funding for SIFAZ, now three years old and operating in five provinces and 27 districts of Zambia.

The cropping practices submitted to the National Advisory Committee by Thierfelder and his colleagues conform to a sustainable intensification assessment framework developed by the Feed the Future Innovation Lab for Collaborative Research on Sustainable Intensification of the US Agency for International Development (USAID) and Kansas State University.

“The framework provides a set of indicators for evaluating technologies according to their effects on productivity, economics, the environment, and social and human conditions — domains considered essential for sustainable agriculture systems,” Thierfelder explained. “The framework is well suited for smallholder farm settings, where agriculture is linked to development goals such as alleviating poverty, avoiding land degradation, increasing food and nutrition security, and supporting women’s empowerment.”

Bringing voluntary carbon offset markets to smallholder Indian farmers

Written by Sarah McLaughlin on November 4, 2022. Posted in Features.

To mitigate their amount of greenhouse gas (GHG) emissions, companies and individuals have access to international voluntary carbon offset markets, which are trading systems that financially compensate credit producer participants for offsetting the amount of carbon emitted. An innovative new initiative from the International Maize and Wheat Improvement Center (CIMMYT) and the Indian Council of Agricultural Research Institute (ICAR) is working to establish carbon markets among smallholder farmers in India, with the goal of reducing GHG emissions, encouraging climate smart farming practices through financial incentives.

In India, agriculture is one of the biggest sources of GHG emissions – between 14 and 21 percent of all GHGs are attributable to agricultural activities, which derive from the use of farm machinery, rice cultivation, fertilizer use, and other activities. Emissions from agriculture are increasing drastically due to synthetic fertilizers and enteric fermentation from livestock.

Within CIMMYT’s farmer-centered approach, participants in voluntary carbon markets will improve their own financial viability in two ways – through adopting sustainable practices and through receipt of payments from carbon markets. The approach will also employ regenerative interventions such as direct dry seeding of rice, minimal tillage, crop diversification, use of biofertilizers, and perennial cropping all while contributing to an overall reduction in GHG emissions.

“Working with ICAR to engage smallholder farmers with high-quality carbon offsets allows the farmers to offset their unavoidable emissions,” said Vijesh Krishna, senior CIMMYT scientist. “This program promotes inclusiveness because this newly created income is distributed among participating farmers, thereby improving their income.”

These regenerative agriculture interventions will increase and retain soil’s carbon content, water permeability and retention, resulting in crops’ ability to withstand drought, flooding, and temperature stresses. Only a small percentage of farmers currently implement these methods in India.

CIMMYT and ICAR researchers estimate that widespread adoption of these practices, combined with upgraded technologies, has the potential to return the carbon levels in agricultural soils from an average of 0.5 percent back to 1.5 percent. At present, the agricultural soils of India are poor with respect to soil organic carbon.

Carbon markets for smallholders

About 2,000 small holder farmers of Punjab, Haryana, and parts of Maharashtra, all in India, are enrolled in the project through individual partnership agreements. Once farmers implement regenerative agricultural methods, they will be eligible to receive payments for carbon credits generated for 10 to 20 years, conditional upon continuing to use climate-smart practices.

“We believe these efforts can be expanded to other regions of India, and other countries,” said Sieg Snapp, CIMMYT’s Sustainable Agrifood Systems (SAS) program director. “Helping farmers and reducing GHG emissions at the same time is the way forward in dealing the crisis of climate change.”

Farms are geo-tagged and monitored using remote sensing for regenerative farming practices, and soil carbon content will be measured at the beginning and end of the crop cycle. Those that produce rice and wheat with a lower carbon footprint will be identified, so their produce gets purchase and price preferences from those who want to promote lower carbon agriculture.

Digital agronomy tools and satellite imagery analysis to measure and verify soil carbon offsets and on-farm GHG emission levels are essential for scaling small farmer-centered carbon projects. The veracity, transparency, and traceability of each carbon offset have direct implications for its credibility and actual market value. CIMMYT will contribute towards a Measurement, Reporting, and Verification (MRV) platform to expand climate action country-wide.

So far, CIMMYT and ICAR researchers estimate that the enrolled smallholder famers have sequestered between four and five tons of carbon dioxide. After independent third-party auditors verify the data, farmers will be paid based on the amount of GHG reduction, with the first carbon offset payments expected to be issued in 2023.

CIMMYT project helps educate farmers in Zimbabwe on seed practices and improved varieties

Written by Tawanda Hove on October 26, 2022. Posted in News.

The International Maize and Wheat Improvement Center is working with its partners to support farmers in Zimbabwe embrace conservation agriculture and improved seed varieties to achieve more successful harvests in areas affected by climate change.

The R4 Rural Resilience and ZAMBUKO initiatives aim to help farmers through a number of activities. These include demonstrations of seed and conservation agriculture, field days and seed fairs, which look to develop farmers’ awareness about improved seed and novel varieties.

The fairs highlighted the importance of good seed practices and the benefits of improved varieties to both farmers and seed companies, who attended the events.

The initiative, which is run in collaboration with the Department of Specialist Services (DRSS), the Agricultural Advisory and Rural Development Services (ARDAS) and the World Food Program (WFP), with financial support from the Swiss Agency for Development and Cooperation (SDC) and the United States Agency for International Development (USAID), helps those in the industry see the advantages of improved varieties over old ones, which may have been on the market for more than 20 years.

“It is now very critical for farmers from all walks of life to abandon old varieties which they have grown for decades and adopt the recently released varieties that offer some solutions to the new challenges,” said James Gethi, a seed systems scientist with CIMMYT. “There has been massive investment in research that has specifically focused on addressing the adversity of climate change and variability it brings, such as prolonged dry spells, heat stress, and new diseases that have emerged. As such, it is beneficial to the farmer to shift to the latest varieties as they suit the environmental context better compared to the older varieties.”

In recent years, Zimbabwe has experienced erratic rainfall and severe heatwaves during summer months, which is a key period for the growth of crops. This has led to low yields in various parts of the country, but the situation could improve through the combination of improved agronomy and varieties presented by seed and seed distribution companies who attended the fairs.

“Together with CIMMYT and other partners, we have invested in developing varieties that will help us achieve our annual food security goals,” added Busiso Mavankeni, head of the Crop Breeding Institute (CBI), which is housed within DRSS. “As such, farmers not adopting these new varieties contribute towards a huge waste of beneficial and relevant scientific research. Whilst it is not the farmers’ fault why they haven’t adopted them, we need to take deliberate steps to ensure farmers are aware of these varieties. That is the only way we can stimulate their adoption.”

Improving seed management

One of the project’s core aims is to promote positive seed management practices to both farmer and seed companies. In fact, these seed companies have a key role to play in supporting farmers with this knowledge. Understanding how to store crops in optimal conditions, for example, can lead to a more successful harvest.

“It is essential for both the farmers and local agro dealers to know how to manage seed before sale and planting,” Gethi added. “For example, rarely do farmers check the expiry date of seed when they buy them from an agro dealer. Secondly, when the seed needs to be stored, it is essential for it not to be stored close to heat sources or to be unnecessarily exposed to the sun for prolonged periods. This compromises its germination potential. Furthermore, it is crucial for farmers to only buy seed from registered and reputable agro dealers.”

These important messages were relayed to farmer throughout the project’s demos and field days, which led up to the seed fairs.

In addition to purchasing seeds, farmers had the opportunity to learn about new developments and build relationships in the private sector by attending the fairs.

“With these seed fairs, we have not only brought this multitude of seed and machinery companies to your doorstep so that you easily access good seeds, but so that you can also talk and understand what new products are on offer,” explained Christian Thierfelder, principal cropping systems agronomist, innovation science leader for Africa within CIMMYT. “For this coming season, we do not want to see you growing ancient varieties but would want to see you purchase new products which perform better than the old ones.”

ARDAS agricultural extension officer Canaan Jakata was also encouraged by the success of the project’s activities and is looking forward to seeing the farmers who attended the seed fairs enjoy a successful yield during the upcoming summer season. “I am very keen on assessing the performance of farmers in my ward who bought these improved varieties at the seed fairs as compared to neighboring wards in the district which did not. Regardless of how the season turns out, I expect superior performance from my farmers,” said Jakata.

Planting Better Seeds a Key for Mexico’s Food Security

Written by Sarah McLaughlin on October 14, 2022. Posted in In the media.

In an article for Mexico Business News, Bram Govaerts, Director General of the International Maize and Wheat Improvement Center (CIMMYT), provides context for the organization’s seed systems strategy in relation to current challenges in agriculture.

Despite producing roughly 27 million tons of white maize used each year, Mexico imports approximately 18 million tons of yellow maize for fodder and raw material. To reduce reliance on imports, productivity of staple crops needs to be increased, during a time when climate change, conflict, COVID-19 and cost of living are all causing additional pressures.

Developing seeds with high yields and resilience to the impacts of climate change is required to close yield gaps in a sustainable way. However, the needs of smallholders differ from those of commercial farming, so inclusivity in seed systems is essential.

The critical role of smallholder farmers of the Eastern Gangetic Plains in the global food chain

Written by Sarah McLaughlin on October 13, 2022. Posted in Features.

The Eastern Gangetic Plains (EGP) are vulnerable to climate change and face tremendous challenges, including heat, drought, and floods. More than 400 million people in this region depend on agriculture for their livelihoods and food security; improvements to their farming systems on a wide scale can contribute to the Sustainable Development Goals (SDGs).

The Australian Centre for International Agricultural Research (ACIAR) has been supporting smallholder farmers to make agriculture more profitable, productive, and sustainable while also safeguarding the environment and encouraging women’s participation through a partnership with the International Maize and Wheat Improvement Center (CIMMYT). On World Food Day, these projects are more important than ever, as scientists strive to leave no one behind.

The EGP have the potential to significantly improve food security in South Asia, but agricultural production is still poor, and diversification opportunities are few. This is a result of underdeveloped markets, a lack of agricultural knowledge and service networks, insufficient development of available water resources, and low adoption of sustainable farming techniques.

Current food systems in the EGP fail to provide smallholder farmers with a viable means to prosper, do not provide recommended diets, and impose undue strain on the region’s natural resources. It is therefore crucial to transform the food system with practical technological solutions for smallholders and with scaling-up initiatives.

ACIAR: Understanding and promoting sustainable transformation of food systems

Over the past ten years, ACIAR has extensively focused research on various agricultural techniques in this region. The Sustainable and Resilient Farming Systems Intensification in the Eastern Gangetic Plains (SRFSI) project sought to understand local systems, demonstrate the efficacy of Conservation Agriculture-based Sustainable Intensification (CASI) approaches, and create an environment that would support and scale-up these technologies.

To establish a connection between research outputs and development goals, the Transforming Smallholder Food Systems in the Eastern Gangetic Plains (Rupantar) project expands on previous work and partnership networks. This is a collaborative venture with CIMMYT that demonstrates inclusive diversification pathways, defines scaling up procedures for millions of smallholder farmers in the region, and produces a better understanding of the policies that support diversification.

Building the future and inspiring communities

Men and women both contribute substantially to farming activities in the EGP of India, Bangladesh, and Nepal, but gender roles differ according to location, crops and opportunities. It is a prevalent perception supported by culture, tradition, and social biases that women cannot be head of the household.

In Coochbehar, India, the unfortunate passing of Jahanara Bibi’s husband left her as head of her household and sole guardian of her only son. Though a tragic event, Bibi never gave up hope.

Going through hardships of a rural single female farmer intensified by poverty, Bibi came to know about CASI techniques and the use of zero-till machines.

Though it seemed like a far-fetched technique at first and with no large network to rely on for advice, Bibi decided to gather all her courage and give it a try. Being lower cost, more productive, adding income, and saving her time and energy all encouraged Bibi to adopt this zero-till machine in 2013, which she uses to this day. Today, she advocates for CASI technology-based farming and has stood tall as an inspiration to men and women.

“I feel happy when people come to me for advice – the same people who once thought I was good for nothing,” said Bibi.

With no regrets from life and grateful for all the support she received, Bibi dreams of her future as a female agro-entrepreneur. Being a lead female farmer of her community and having good contact with the agriculture office and conducive connection with local service providers, she believes that her dream is completely achievable and can inspire many single rural female farmers like herself to encourage them to change perceptions about the role of women.

Stepping up for South Asian women

Written by Nima Chodon on October 7, 2022. Posted in Features.

Women play an integral role in all stages of agrifood systems, yet their unpaid labor is often culturally and economically devalued and ignored. As agriculture becomes more female-oriented, women are left with a double workload of caring in the home and laboring in the fields, leaving no time for leisure. Training programs are often developed with only male farmers in mind, and women can be completely excluded when it comes to mechanization.

The Cereal Systems Initiative for South Asia (CSISA), established by the International Maize and Wheat Improvement Center (CIMMYT), and implemented jointly with the International Food Policy Research Institute (IFPRI), the International Water Management Institute (IWMI) and the International Rice Research Institute (IRRI), is empowering women to become active participants in farming, improving their abilities and confidence through training, expanded access to machinery and better crop management practices. To celebrate International Day of Rural Women, here are stories from three of the women CIMMYT has helped.

Equality in agricultural opportunities

Nisha Chaudhary and her husband Kamal were engaged in agriculture, poultry and pig farming in Nepal, but struggled to provide for their family of seven; their combined income was never sufficient for them to make ends meet.

Through the CSISA COVID-19 Response and Resilience Activity, CIMMYT introduced Chaudhary to mechanization’s advantages and supported her to connect with banks, cooperatives, and machinery dealers to access financial support to introduce agriculture machinery into the family business. She became the first farmer in her village to acquire a mini combine rice mill and offer milling services. The following month, Chaudhary received additional tutoring from the Activity, this time in business management and mill repair and maintenance.

Learning about mechanization was eye-opening for Chaudhary, particularly as the Bankatti community that she comes from uses traditional methods or travels great distances to process grains using machines hired out by other communities.

Chaudhary’s primary income is now from her milling services, offering post-harvest processing services to 100 households and earning more than $150 USD each month; after deducting expenses, she is still able to save around $50 USD every month. She has bought four more cows, increasing the number of cattle she owns from 12 to 16, and is able to make her own for her livestock, saving an additional $20 USD per month.

Giving rural women the credit they deserve

As part of its response to the pandemic, CSISA launched a COVID-19 Response Activity aimed at supporting farmers and service providers to access subsidies and collateral-free loans via the Government of Nepal Kisan Credit Card (KCC) scheme, designed to support agriculture-related businesses. Through this scheme, farmers received hands-on training in providing after-sales support to customers, as well as mentoring to learn how to operate machinery and use it to generate sales and income.

Smallholder female farmers have been subject to many hardships due to lack of access to finance. They are forced to sell produce at low prices and buy inputs at high prices, which makes them suffer financially and physically. Now, loans through appropriate intermediaries can foster rural entrepreneurship and the service delivery business model.

The KCC scheme gave Chaudhary financial security just when she needed it. Her next step, with her newfound confidence, respect of her community, and the support of a collateral-free loan from KCC, will be to launch her own poultry farm agri-business.

Eradicating discrimination in mechanization

The CSISA Mechanization and Extension Activity (CSISA-MEA) enables smallholder female farmers to discover the advantages of scale-appropriate mechanization and its benefits: increased productivity, reduced labor costs, improved financial stability and greater food security.

Rokeya Begum was a stay-at-home mother to three children in Bangladesh and aspired to give her daughter a good education. However, her husband found it difficult to sustain the family as a factory worker due to the high cost of their daughter’s education.

As a result, Begum opted to work in an agriculture machinery manufacturing workshop like her husband. She was initially hesitant to work in a male-dominated workplace but on the other hand realized that this job would mean she could pursue the dream she had for her daughter. She immediately began using her earnings to fund her daughter’s education, who is currently in high school.

Begum was part of the grinding and painting departments at M/S Uttara Metal Industries in Bogura, Bangladesh, for five years. Her weekly wage was equivalent to $12 USD – insufficient to support her family or sustain a decent quality of life.

CSISA-MEA included Begum in skills training, which proved to be a gamechanger. She participated in CIMMYT’s training on spray gun painting, as well as in fettling and grinding skills. As part of both training programs, she learnt how to handle an air compressor paint gun and painting materials, as well as different painting methods. She has also learnt more about keeping herself safe at work using personal protective equipment. “Before the training, I did not know about the health risks – now I don’t work without PPE,” she said.

Begum used to paint the traditional way with a brush, but now the owner permits her to paint with a spray gun with her increased expertise. As a result, she has been promoted from day laborer to contractual employee in painting and grinding, with a new weekly salary of $50 USD. Her confidence has grown to the extent that she is comfortable in an engineering workshop among male coworkers.

Harvesting the benefits of improved practices

Farmer and mother of six, Malti Devi has an infectious smile that hardly reveals the toil and labor of her everyday farm work in India.

She grows wheat on nearly 0.45 acres of leased land. Her husband, a barber, earns an ordinary income that is insufficient for a family of eight. Despite the challenges, Devi has managed to earn income through her efforts in the field and by working as a daily wager in nearby fields.

To support women farmers like Devi, CSISA made efforts to build relationships via on-the-ground partnerships with civil society, women’s cooperatives like JEEViKa in Bihar and Mission Shakti in Odisha, or self-help groups. The team provides in-field demonstrations, training, workshops on best practices and support with access to better seed varieties and extension services. CSISA’s integrated approaches reach these women with information and associated technology that best serves them, while being climate-smart and sustainable.

Devi expressed that due to zero-till practice encouraged by the CSISA team, she saved time in the planting season, which she devoted to working on other’s fields for extra income. “The traditional method would have left me struggling for time, on the field or at home. Practices like zero-till ensured our crop was harvested on time with reduced input costs and resources and enabled a good harvest for consumption, and we could also sell some produce.”

Devi has ensured self-sufficiency for her family through her efforts and hopes to make use of the support in better crop management on offer from CSISA for wheat and other crops.

Expanding BISA expertise to new horizons in South Asia

Written by Richa Sharma Puri on October 5, 2022. Posted in Features.

Ten years ago, a foundation was laid on the principles of Norman Borlaug to translate agrarian challenges into opportunities through collaboration between the International Maize and Wheat Improvement Centre (CIMMYT) and the Indian Council of Agricultural Research (ICAR). This major step toward sustainable food and nutrition security was taken through the establishment of the Borlaug Institute for South Asia (BISA) as an independent, non-profit research organization.

Today, BISA is a global name in agriculture research with a vision to promote food security, nutrition, stable livelihoods, and eco-friendly practices in South Asia. Given the prominent challenges of climate change in these economically fragile agroecosystems, the partnership between BISA, ICAR, and CIMMYT plays a pivotal role in developing improved wheat and maize varieties with climate-smart and conservation agriculture-based practices.

A decade of impact

One of the most significant outcomes of BISA’s work has been its contribution to building a vast, solid network for evaluating and disseminating new high-yielding and climate-resilient wheat varieties for India and other South Asian countries in close partnership with ICAR and CIMMYT. BISA’s transformative solutions and science-led research are critical to targeting stressed resources and attaining global food security.

With support from ICAR and CIMMYT, BISA has developed state-of-the-art research facilities at its three strategically selected research stations, having 1,200 acres of land that the Government of India, jointly with the respective state governments, generously granted to the project. Located in three disparate agro-climatic and socioeconomic environments, these sites are model research farms supporting agriculture research in South Asia. The learning labs at BISA emphasize that scaling climate-smart villages also strengthen climate-resilient agriculture, primarily through addressing challenges such as residue burning. BISA’s collaborative and inclusive approach is more relevant today when the world is grappling with various food and nutrition insecurity challenges.

Time for expansion

BISA envisages attracting countries from south Asia, the Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation (BIMSTEC) and the South Asian Association for Regional Cooperation (SAARC), as well as National Agricultural Research Systems (NARS), national research institutes, private sector companies, and civil society organizations as active partners for expanding reach in the region. To this end, BISA has completed extensive work in Nepal and Bangladesh and has extended its services to Bhutan and Sri Lanka.

Still, more needs to be done in South Asian countries. Therefore, there is an urgent need for a strong commitment to harnessing the best of international scientific discoveries with local efforts. Collective action is to be garnered to provide trusted and effective mechanisms for developing and sharing cutting-edge agricultural technologies in the South Asian region.

To this end, a BISA High-Level Meeting was organized on September 1 and 2 in Delhi, with senior government representatives from the NARS in Bhutan, Sri Lanka, Pakistan, Nepal, Bangladesh, and India. The meeting provided a forum to identify opportunities to co-create and deploy innovative, multidisciplinary solutions to effectively address the transboundary challenges related to food, nutrition, and environmental security faced by farming communities in South Asia. This platform strives to unite the scientific community and thought leaders to support research and development across the agriculture domain.

Delegates from these countries felt that there is a need for a robust program of germplasm exchange within the region, which is essential to strengthening agriculture’s resilience. All countries expressed a significant need to raise their capacity of young researchers in advanced research techniques related to genomics, phenotyping, climate-smart agriculture, precision agriculture, and digital technologies. Delegates also discussed BISA’s role as a research and innovation regional catalyst, innovation hub, and integrated research platform to build resilient agrifood systems and achieve long-term sustainability and resilience for food security in South Asia.

BISA’s farm-ready research, from setting up climate-resilient villages and developing viable alternatives to rice residue burning to facilitating an open exchange of elite germplasm and cutting-edge technologies, reflects not only the vision of CIMMYT but also the philosophy of our mutual inspiration, Borlaug, who believed strongly in sharing knowledge and “taking it to the farmer”.

The potential of conservation agriculture in increasing yield and tackling climate change

Written by Celine Lim on August 22, 2022. Posted in Publications.

A multitude of research on the benefits of conservation agriculture in South Asia has predominantly focused on favorable environments where farmers have reliable access to energy supporting irrigation and inputs.

In this new publication, scientists from the International Maize and Wheat Improvement Center (CIMMYT) explore the performance of conservation agriculture in under-developed coastal environments in southern coastal Bangladesh over a period of three consecutive years, including under rainfed conditions and/or with limited application of irrigation.

Responding to the identified research gap, this research tests the hypothesis that seasonally alternating tillage (SAT) practices that alternate between strip-tillage in the winter season for maize and conventional tillage (CT) prior to rice can reduce energy use, increase energy productivity, and reduce yield-scaled emissions while increasing or maintaining yield and profit, even under these challenging conditions.

Working with 35 farmers who managed experiments in partially irrigated and rainfed environments in southern coastal Bangladesh, researchers teamed up with farming communities to compare the full suite of conservation agriculture to SAT practices against CT and farmer’s own practices.

The research found that in these coastal environments, both conservation agriculture and SAT practices have the potential to increase cereal yields and energy productivity while reducing yield-scaled emissions, thereby enabling farmers even in challenging coastal environments to produce more while reducing energy use and mitigating greenhouse gas emissions.

However, in consideration of farmers’ aversion to the elimination of tillage in rice, the research suggests that adaptations in CA practices and seasonal tillage prior to rice may be a more practical fit for rice-maize systems managed by smallholders reluctant to eliminate tillage for rice in coastal Bangladesh.

This research gives implications for future research and development efforts to take into consideration farmers’ preferences or the trade-offs resulting from significant change to conservation agriculture management in otherwise fully tilled systems. It is also vital to integrate development efforts that focus not only on agronomic management, but also on building supportive value chains to improve availability and affordability of the inputs and farm machinery required to successfully establish crops with such practices.

Conservation agriculture practices revive saline and sodic soils

Written by Sarah McLaughlin on August 17, 2022. Posted in Publications.

In arid and semi-arid regions, soil salinity and sodicity pose challenges to global food security and environmental sustainability. Globally, around 932 million hectares are affected by salinization and alkalinization. Due to growing populations, anthropogenic activities and climate change, the prominence of salt stress in soil is rising both in irrigated and dryland systems.

Scientists from the International Maize and Wheat Improvement Center (CIMMYT) and the Indian Council of Agricultural Research (ICAR) employed long-term conservation agriculture practices in different agri-food systems to determine the reclamation potential of sodic soil after continuous cultivation for nine years, with the experiment’s results now published.

Using different conservation agriculture techniques on areas cultivating combinations of maize, wheat, rice and mungbean, the study used soil samples to identify declines in salinity and sodicity after four and nine years of harvesting.

Evidence demonstrates that this approach is a viable route for reducing soil sodicity and improving soil carbon pools. The research also shows that the conservation agriculture-based rice-wheat-mungbean system had more reclamation potential than other studied systems, and therefore could improve soil organic carbon and increase productive crop cultivation.

Understanding the role of organic material application in soil microbial community structures

Written by Sarah McLaughlin on August 8, 2022. Posted in Publications.

While previous studies have demonstrated the importance of organic material in soil for sustainable agricultural practices, there has been limited research into how organic material application affects the soil microbial community structures.

Researchers from El Centro de Investigación y de Estudios Avanzados del Instituto Politécnico Nacional (CINVESTAV) studied soil from the International Maize and Wheat Improvement Center’s (CIMMYT) long-term experiment in northwestern Mexico to determine the effect on the soil metagenome after adding easily decomposable organic residues. The soil was collected from plots where maize and wheat were cultivated without tillage on permanent beds with crop residue left on the soil surface since 1992.

Dried young maize plants were added to the soil in the laboratory. After three days of incubation, soil samples were analyzed using shotgun metagenomic sequencing to discover how the application of young maize plants affects the structure of microbial communities in arable soil, how the potential functioning of microbial communities is altered, and how the application affects the soil taxonomic and functional diversity.

Bacterial and viral groups were strongly affected by organic material application, whereas archaeal, protist and fungal groups were less affected. Soil viral structure and richness were impacted, as well as metabolic functionality. Further differences were recorded in cellulose degraders with copiotrophic lifestyle, which were enriched by the application of young maize plants, while groups with slow growing oligotrophic and chemolithoautotrophic metabolism performed better in unamended soil.

Given the importance of embedding and adopting sustainable agricultural practices as part of climate change adaptation and mitigation, the study improves our insight in a key aspect of sustainable agriculture, the management of crop residues.

An international team of scientists has found that eco-friendly practices such as growing a range of crops, including legumes such as beans or pigeonpea, and adding plant residues or manure to soils can raise food crop yields in places such as rural Africa, where small-scale farmers cannot apply much nitrogen fertilizer.

Published in the science journal Nature Sustainability and examining data from 30 long-running field experiments involving staple crops (wheat, maize, oats, barley, sugar beet, or potato) in Europe and Africa, this major study is the first to compare farm practices that work with nature to increase yields and explore how they interact with fertilizer use and tillage.

“Agriculture is a leading cause of global environmental change but is also very vulnerable to that change,” said Chloe MacLaren, a plant ecologist at Rothamsted Research, UK, and lead author of the paper. “Using cutting-edge statistical methods to distill robust conclusions from divergent field experiment data, we found combinations of farming methods that boost harvests while reducing synthetic fertilizer overuse and other environmentally damaging practices.”

Recognizing that humanity must intensify production on current arable land to feed its rising numbers, the paper advances the concept of “ecological intensification,” meaning farming methods that enhance ecosystem services and complement or substitute for human-made inputs, like chemical fertilizer, to maintain or increase yields.

Boosting crop yields and food security for far-flung smallholders

The dataset included results from six long-term field experiments in southern Africa led by the International Maize and Wheat Improvement Center (CIMMYT). Africa’s farming systems receive on average only 17 kilograms of fertilizer per hectare, compared to more than 180 kilograms per hectare in Europe or close to 600 in China, according to Christian Thierfelder, a CIMMYT cropping systems agronomist and study co-author.

“In places where farmers’ access to fertilizer is limited, such as sub-Saharan Africa or the Central American Highlands, ecological intensification can complement scarce fertilizer resources to increase crop yields, boosting households’ incomes and food security,” Thierfelder explained. “We believe these practices act to increase the supply of nitrogen to crops, which explains their value in low-input agriculture.”

The CIMMYT long-term experiments were carried out under “climate-smart” conservation agriculture practices, which include reduced or no tillage, keeping some crop residues on the soil, and (again) growing a range of crops.

“These maize-based cropping systems showed considerable resilience against climate effects that increasingly threaten smallholders in the Global South,” Thierfelder added.

Benefits beyond yield

Besides boosting crop yields, ecological intensification can cut the environmental and economic costs of productive farming, according to MacLaren.

“Diversifying cropping with legumes can increase profits and decrease nitrogen pollution by reducing the fertilizer requirements of an entire crop rotation, while providing additional high-value food, such as beans,” MacLaren explained. “Crop diversity can also confer resilience to weather variability, increase biodiversity, and suppress weeds, crop pests and pathogens; it’s essential, if farmers are to improve maize production in places like Africa.”

Thierfelder cautioned that widespread adoption of ecological intensification will require strong support from policymakers and society, including establishing functional markets for legume seed and for marketing farmers’ produce, among other policy improvements.

“Dire and worsening global challenges — climate change, soil degradation and fertility declines, and scarcening fresh water — threaten the very survival of humanity,” said Thierfelder. “It is of utmost importance to renovate farming systems and bring us back into a safe operating space.”

Timothy Reeves, who served as director general of the International Maize and Wheat Improvement Center (CIMMYT) from 1995 to 2002, has been included in Queen Elizabeth II’s Birthday Honours List. He has been appointed a Member (AM) of the Order of Australia, for his significant service to sustainable agriculture research and production.

“I’m overwhelmed. I feel so honored and wish to also recognize the wonderful people that I have worked with — both farmers and scientists — here in Australia, and around the world. I also acknowledge my beautiful family without whom it would have not been possible,” he said.

Reeves was a pioneer of direct drilling and conservation agriculture in Australia in the 1960s and 70s. This method of planting crops which requires no cultivation of the land, is now the direct-drilling method used by 90% of farmers across Australian cropping regions. He and colleagues in the Victorian Department of Agriculture also worked at that time on the introduction of new crops into farming systems, including lupins, canola and faba beans.

He was appointed to the role of director general of CIMMYT in 1995, based in Mexico for seven years, helping developing countries with food and nutritional security. He is the only Australian to have held this position.

Reeves is currently an Honorary Professorial Fellow at the Faculty of Veterinary and Agricultural Sciences, University of Melbourne. He is heavily involved with passing on his knowledge to his academic colleagues and to both undergraduate and postgraduate students. Reeves’s academic writings include publishing more than 180 papers, book chapters and articles. He is also a Chair of the Agriculture Forum of the Australian Academy of Technological Sciences and Engineering.

A climate-smart remodeling of South Asia’s rice-wheat cropping is urgent

Written by Mike Listman on June 3, 2022. Posted in Publications.

A climate change hotspot region that features both small-scale and intensive farming, South Asia epitomizes the crushing pressure on land and water resources from global agriculture to feed a populous, warming world. Continuous irrigated rice and wheat cropping across northern India, for example, is depleting and degrading soils, draining a major aquifer, and producing a steady draft of greenhouse gases.

Through decades-long Asian and global partnerships, the International Maize and Wheat Improvement Center (CIMMYT) has helped to study and promote resource-conserving, climate-smart solutions for South Asian agriculture. Innovations include more precise and efficient use of water and fertilizer, as well as conservation agriculture, which blends reduced or zero-tillage, use of crop residues or mulches as soil covers, and more diverse intercrops and rotations. Partners are recently exploring regenerative agriculture approaches — a suite of integrated farming and grazing practices to rebuild the organic matter and biodiversity of soils.

Along with their environmental benefits, these practices can significantly reduce farm expenses and maintain or boost crop yields. Their widespread adoption depends in part on enlightened policies and dedicated promotion and testing that directly involves farmers. We highlight below promising findings and policy directions from a collection of recent scientific studies by CIMMYT and partners.

Getting down in the dirt

A recent scientific review examines the potential of a suite of improved practices — reduced or zero-tillage with residue management, use of organic manure, the balanced and integrated application of plant nutrients, land levelling, and precise water and pest control — to capture and hold carbon in soils on smallholder farms in South Asia. Results show a potential 36% increase in organic carbon in upper soil layers, amounting to some 18 tons of carbon per hectare of land and, across crops and environments, potentially cutting methane emissions by 12%. Policies and programs are needed to encourage farmers to adopt such practices.

Another study on soil quality in India’s extensive breadbasket region found that conservation agriculture practices raised per-hectare wheat yields by nearly half a ton and soil quality indexes nearly a third, over those for conventional practices, as well as reducing greenhouse gas emissions by more than 60%.

Ten years of research in the Indo-Gangetic Plains involving rice-wheat-mungbean or maize-wheat-mungbean rotations with flooded versus subsoil drip irrigation showed an absence of earthworms — major contributors to soil health — in soils under farmers’ typical practices. However, large earthworm populations were present and active under climate-smart practices, leading to improved soil carbon sequestration, soil quality, and the availability of nutrients for plants.

Rebooting marginal farms by design

Using the FarmDESIGN model to assess the realities of small-scale, marginal farmers in northwestern India (about 67% of the population) and redesign their current practices to boost farm profits, soil organic matter, and nutritional yields while reducing pesticide use, an international team of agricultural scientists demonstrated that integrating innovative cropping systems could help to improve farm performance and household livelihoods.

More than 19 gigatons of groundwater is extracted each year in northern India, much of this to flood the region’s puddled, transplanted rice crops. A recent experiment calibrated and validated the HYDRUS-2D model to simulate water dynamics for puddled rice and for rice sown in non-flooded soil using zero-tillage and watered with sub-surface drip irrigation. It was found that the yield of rice grown using the conservation agriculture practices and sub-surface drip irrigation was comparable to that of puddled, transplanted rice but required only half the irrigation water. Sub-surface drip irrigation also curtailed water losses from evapotranspiration and deep drainage, meaning this innovation coupled with conservation agriculture offers an ecologically viable alternative for sustainable rice production.

Given that yield gains through use of conservation agriculture in northern India are widespread but generally low, a nine-year study of rice-wheat cropping in the eastern Indo-Gangetic Plains applying the Environmental Policy Climate (EPIC) model, in this case combining data from long-term experiments with regionally gridded crop modeling, documented the need to tailor conservation agriculture flexibly to local circumstances, while building farmers’ capacity to test and adapt suitable conservation agriculture practices. The study found that rice-wheat productivity could increase as much as 38% under conservation agriculture, with optimal management.

Q&A: Regenerative agriculture for soil health

Written by Madeline Dahm on May 9, 2022. Posted in Features.

South Asia was the epicenter of the Green Revolution, a historic era of agricultural innovation that fed billions of people on the brink of famine.

Yet despite the indisputably positive nutritional and developmental impacts of the Green Revolution of the 1960s, the era of innovation also led to the widespread use of farming practices—like intensive tilling, monoculture, removal and burning of crop residues, and over-use of synthetic fertilizer—that have a deleterious effect on the soil and cause off-site ecological harm. Excess pumping of irrigation water over decades has dried out the region’s chief aquifer.

South Asia’s woes illustrate the environmental costs of intensive food production to feed our densely-populated planet. Currently, one billion hectares of land worldwide suffers from degraded soils.

The International Maize and Wheat Improvement Center (CIMMYT) works with two of the world’s most widely cultivated and consumed cereal crops. To grow enough of these staple foods to feed the world, a second Green Revolution is needed: one that avoids the mistakes of the past, regenerates degraded land and reboots biodiversity in farm areas.

M.L. Jat, a CIMMYT Principal Scientist, has spent 20 years studying and promoting sustainable agricultural practices for maize- and wheat-based farming systems. In the following Q&A, Jat tells us about regenerative agriculture: integrated farming and grazing practices intended to rebuild soil organic matter and restore degraded soil biodiversity.

Q: What major components or practices are part of regenerative agriculture?

A: Regenerative agriculture is a comprehensive system of farming that harnesses the power of soil biology to rebuild soil organic matter, diversify crop systems, and improve water retention and nutrient uptake. The depletion of biodiversity, degradation of soil health, warming, and drier weather in farm areas have necessitated a reversal in agriculture from “degeneration to regeneration.”

The practices address food and nutritional security challenges while protecting natural resources and lowering agriculture’s environmental footprint, in line with the United Nations Sustainable Development Goals. CIMMYT has worked for years to research and promote conservation agriculture, which contributes to the aims of regenerative agriculture, and is already practiced on more than 200 million hectares globally — 15% of all cropland — and is expanding at a rate of 10.5 million hectares per year.

Q: What are the potential roles of major food crops — maize, rice, and wheat — in regenerative agriculture systems?

A: Regenerative agriculture is “crop neutral;” that is, it is applicable to almost all crops and farming systems. The world’s rice, wheat, and maize crops have an enormous physical and ecological footprint on land and natural resources, but play a critical role in food and nutrition security. Considering that anthropogenic climate change has reduced the global agricultural total factor productivity by about 21% in the past six decades, applying regenerative agriculture approaches to these systems represents a momentous contribution toward sustainable farming under increasing climatic risks.

Q: What elements or approaches of regenerative agriculture are applicable in India and how can they be applied?

A: Regenerative practices for maize and wheat systems in India include no-tillage, crop residue recycling, legume inter-cropping and cover crops, crop diversification, integrated nutrient management, and precision water management.

The potential area of adoption for regenerative agriculture in India covers at least 50 million hectares across a diversity of cropping systems and agroecologies — including irrigated, rainfed, and arid farmlands — and can be approached through appropriate targeting, investments, knowledge and capacity enhancement, and enabling policies.

In the breadbasket region of the Indo-Gangetic Plains, regenerative agriculture can help address the aforementioned second-generation problems of the Green Revolution, as well as contributing to the Indian government’s Soil Health Mission and its COP26 commitments.

Q: In order to get regenerative agriculture off the ground in South Asia, who will be involved?

A: Adapting and applying regenerative agriculture’s portfolio of practices will require the participation of all stakeholders associated with farming. Application of these principles is location- and situation-specific, so researchers, extension functionaries, value chain actors, philanthropists, environmentalists, NGOs, farmers, and policy planners all have a role to play in the impact pathway.

CIMMYT, the Borlaug Institute for South Asia (BISA), public and private programs and agencies, and farmers themselves have been developing, refining, and scaling out conservation agriculture-based regenerative agriculture practices for some three decades in South Asia. CIMMYT and BISA will continue to play a key role in mainstreaming regenerative agriculture in local, national, and regional development plans through science-based policy and capacity development.

Q: Farmers constitute a strong economic and political force in India. How can they be brought on board to practice regenerative agriculture, which could be more costly and knowledge-intensive than their current practices?

A: We need to pursue business “unusual” and harness the potential opportunities of regenerative agriculture to sequester soil carbon and reduce greenhouse gas emissions. Regenerative agriculture practices can offer farmers additional income and certainly create a “pull factor” for their adoption, something that has already started and will constitute a strong business case. For example, innovative business models give farmers an opportunity to trade ecosystem services and carbon credits through repurposing subsidies and developing carbon markets for private sectors. CIMMYT, along with the Indian Council of Agricultural Research and private partners such as Grow Indigo, are already helping to put in place a framework to acquire carbon credits through regenerative agriculture in India.

Turning the mechanization wheels on Zimbabwe’s small-scale farms

A new project aims to climate-proof Zimbabwean farms through improved access to small-scale mechanization to reduce labor bottlenecks. Harnessing Appropriate-scale Farm mechanization In Zimbabwe (HAFIZ) is funded by the Australian Department of Foreign Affairs and Trade (DFAT) through ACIAR and led by the International Maize and Wheat Improvement Center (CIMMYT).

The project aligns with the Zimbabwean nationwide governmental program Pfumvudza, which promotes agricultural practices based on the principles of conservation agriculture. The initiative aims to increase agricultural productivity through minimum soil disturbance, a permanent soil cover, mulching and crop diversification.

Over 18 months, the project will work with selected service providers to support mechanized solutions that are technically, environmentally and economically appropriate for use in smallholder settings.

Speaking during the project launch, the Permanent Secretary of the Ministry of Lands, Agriculture, Fisheries, Water and Rural Development in Zimbabwe, John Basera, explained the tenets of Pfumvudza which translates as “a new season.” A new season of adopting climate-smart technologies, conservation agriculture practices and increasing productivity. Simply put, Pfumvudza means a sustainable agricultural productivity scheme.

“Pfumvudza was a big game-changer in Zimbabwe. We tripled productivity from 0.45 to 1.4 [metric tons] per hectare. Now the big challenge for all of us is to sustain and consolidate the growth, and this is where mechanization comes into place,” Basera said. “This project is an opportunity for the smallholder farmer in Zimbabwe, who contributes to over 60% of the food in the country, to be able to produce more with less.”

The mechanics of sustainable intensification

Building on the findings of the completed ACIAR-funded project Farm Mechanization and Conservation Agriculture for Sustainable Intensification (FACASI), the new initiative will work with selected farmers and service providers to identify farming systems most suitable for mechanization. It will also assist companies in targeting their investments as they test a range of technologies powered by small-engine machinery adapted to the Zimbabwe context and transfer the resultant learnings to South Africa.

Conservation agriculture adoption offers multidimensional benefits to the farmers with significant yields and sustainability of their systems. The introduction of mechanization in systems using animals for draught reduces the livestock energy demand — energy that will contribute to increasing meat and milk production.

While conservation agriculture and research alone cannot solve all the issues affecting agricultural productivity, awareness-raising is integral to help address these issues, and this is where small-scale mechanization comes in, says ACIAR Crops Research Program Manager, Eric Huttner.

“We learnt a lot from FACASI and a similar project in Bangladesh on the opportunities of appropriate small-scale mechanization as a tool towards sustainable intensification when adopted by farmers,” he explained. “If we avoid the mistakes of the past, where large-scale mechanization efforts were invested in the wrong place and resulted in ineffective machines unusable for farmers, we can make a huge difference in increasing yields and reducing farm drudgery,” Huttner said.

The project is funded by DFAT through ACIAR and implemented by the International Maize and Wheat Improvement Center (CIMMYT) in partnership with the Zimbabwe Ministry of Lands, Agriculture, Fisheries, Water and Rural Development, the University of Zimbabwe, the University of Kwa Zulu Natal in South Africa and private sector companies – Kurima, Zimplow and Hello Tractor.
