When she first ventured into growing pigeon peas as a baby trial host farmer, Gogo Consilia Nyamunda doubted that intercropping them with maize would bring any benefits, especially given the weather had not been lenient over the past few years in Buhera district, in eastern Zimbabwe. “This year has been the hardest. I’ve never experienced such drought and heat stress, but it’s not just me—it’s affecting the entire country,” says Gogo Consilia. Yet, her production turned out to be better than that of farmers growing only maize, a popular crop in Southern Africa. Encouraged by the results, she expanded her efforts, dedicating half a hectare to pigeon peas. “From just 0.2 hectares of pigeon peas, I still managed to harvest 10 kilograms in these extremely dry conditions. It’s not just for feeding my chickens—other farmers are now interested in the seeds as well,” she explains.

Gogo Consilia Nyamunda is one of twelve farmers experiencing new feed production practices as part of the Livestock Production Systems in Zimbabwe (LIPS-Zim) project, rolled out since 2020 by the International Livestock Research Institute (ILRI) in partnership with CIMMYT, the French Agricultural Research Center for International Development (CIRAD), and the University of Zimbabwe (UZ).

In the face of a changing climate, building the resilience of local farmers is crucial to safeguarding both their meal baskets and livestock feed. In this context, LIPS Zimbabwe has emerged as a strategic initiative, deeply rooted in farmer-driven trials to scale fodder production while maximizing the potential of mechanization for smallholder farmers in Buhera. By integrating improved agronomic practices with scalable fodder production, LIPS Zimbabwe is helping farmers withstand the challenges posed by climate change.

Empowering local farmers through fodder production

In the same district, Shirley Makoni also began as a baby trial farmer, intercropping maize with jack bean, a leguminous crop resilient to drought. Her case highlights the importance of diversifying crops and adapting to the realities of climate change: despite initial skepticism, Shirley found that jack beans not only survived the drought but also provided valuable feed for her cows. “I didn’t think anything would come out of it, but the cows love the leaves and seeds. They’ve gained weight, and the crop has been easy to manage,” she shares. While her maize and other crops failed due to the severe weather, jack bean proved to be a reliable source of feed, allowing her to bale the leaves and even share the harvest with others.

One of the key strategies employed by LIPS Zimbabwe is the promotion of resilient fodder crops that can thrive under harsh climatic, semi-arid conditions where potential evapotranspiration far exceeds seasonal rainfall, which is often below 600 mm. This approach not only ensures a reliable source of feed for livestock but also contributes to the overall resilience of farming systems. The success story of farmers like Gogo Consilia Nyamunda highlights the transformative impact of these efforts.

“The idea of testing new innovations has paid off. Despite the poor sandy soils in Buhera, these fodder crops (jack bean and pigeon pea) have done well!” says Isaiah Nyagumbo, a Systems Agronomist leading the CIMMYT component of the LIPS-Zim project. “This means we now have a more diverse range of leguminous fodder crop species that can be grown in these semi-arid conditions, apart from the more common ones such as mucuna, lablab, and cowpeas.”

Some preliminary laboratory results also suggest that jack bean contains much higher crude protein than popular fodder legumes like mucuna. Jack bean could thus offer a new resilient feed option for farmers in these drought-prone regions and can be grown as an intercrop or in rotation with cereals.

Transforming fodder production through mechanization

Tying the LIPS Zimbabwe project together is the introduction of the mechanization component, from planting to processing the fodder crops, which is crucial for increasing the scale of fodder production in Zimbabwe’s semi-arid regions. By processing forage legumes such as jack bean, lablab, pigeon pea, mucuna, and cowpea, farmers can ensure a steady supply of nutritious feed for their livestock, even in the face of unpredictable weather patterns.

Local farmers in Buhera have been equipped with machinery such as a chopper grinder, hay balers, planters, and tractors, and trained to use and maintain the equipment. “Among the machinery at hand, the hay baler has been a great win for me, especially for the cows,” says Gandani Nhachi. “Last season, I made 27 bales of fodder, which has been vital for my herd. I’ve also grown my goat herd from 16 last year to 35 this year,” he proudly shares.

Building resilience for the future

As climate change continues to challenge farmers, initiatives like LIPS Zimbabwe are essential for building resilience. By combining traditional knowledge with modern practices, scaling fodder production, and embracing mechanization, farmers in Buhera are better equipped to protect their livelihoods and ensure food security. As Gandani puts it, “Climate change is inevitable, but with the right practices, we can still thrive. When I give my goats food, they multiply. Even if one side fails, all hope is not lost.”

How livestock vaccination campaigns support breeders in conflict-ridden Sudan

Written by Julian Bañuelos-Uribe on . Posted in Blogs.

Ali Hassan is a 38-year-old herder living in Al Showak, Gadarif, Sudan. Like thousands of traditional animal breeders in Sudan, Ali works hard to take care of his fast-growing flock of animals.

During the past few months, with the ongoing civil war, Ali was a little concerned that he was not getting the veterinary advice that he needed, because of the limited coverage in his area by veterinary services, and that he might lose some of his animals due to the lack of a vaccination service.

Ali was very happy when his neighbor Ahmed told him that Catholic Relief Services (CRS) had trained him as a community animal health worker (CAHW) through the USAID-funded SASAS. Ahmed started to visit Ali to check on his animals and give him valuable advice and tips on how to keep his animals healthy and better fed.

Due to the ongoing armed conflict in Sudan, the local animal health care service has been massively interrupted. CRS, through the USAID-funded SASAS, are currently conducting an animal vaccination campaign in Gadarif in the eastern part of the country.

Catholic Relief Services uses trained community networks to inform herders of the locations where animal vaccinations are taking place and to raise awareness of the importance of having their animals vaccinated.

Trained CAHWs, led by official animal health workers, are driving a massive animal vaccination campaign targeting 150,000 head of goats and sheep in the Gala Alnahal, Al Fao, and Al Showak localities in the traditionally animal-rich Gadarif state.

The well-trained and sufficiently well-equipped CAHWs are driving the campaign showing unflagging dedication and using innovative methods to significantly reduce animal disease, making a remarkable achievement in the ongoing fight against deadly diseases. CAHWs actively promote the dissemination of veterinary education and health care locally, and the improvement of animal health and husbandry through education, veterinary services, enterprise development, and enhanced trade.

“At SASAS, we work to transform the livestock meat value chain to become productive, sustainable, and market oriented. Further, SASAS works with community members in the targeted localities to equitably share natural resources and peacefully engage in mutually beneficial activities”, said Abdelrahman Kheir, SASAS chief of party in Sudan.

The CAHWs were extensively trained and provided with firsthand experience of the basic principles of animal health; animal husbandry and production; basic clinical and husbandry procedures; basic animal disease management; safe food; drug administration; meat inspection at slaughterhouses; common animal diseases; community engagement; and running animal health service activities. In addition, CAHWs check the health of the animals at the slaughterhouses in the various areas targeted by the project.

To ensure gender equity and make sure that no one is excluded, both male and female community members are trained as CAHWs. Fatima is 45 years old and is a local female herder living in Al Fao, Gadarif State; she was looking for a chance to improve her skills in animal breeding and in helping herders within her community. After getting the necessary theoretical and practical training in animal health, Fatima was equipped with a veterinary toolkit and a donkey cart to increase her mobility, while male CAHWs were provided with bicycles to help them travel around and provide veterinary services within their communities.

To enhance the livestock value chain, the CRS are constructing slaughter slabs in the areas targeted by the project in coordination with the local animal health authorities and the community.

Agriculture, including livestock and fishing, is the most important economic sector in Sudan, contributing about a third of the country’s GDP and providing a livelihood for about two-thirds of the active population. The export of livestock has become an increasingly important part of the economy, competing with cash crop sales as the fastest growing, non-oil export sector. Camels, cattle, sheep, and goats are exported mainly to Saudi Arabia, other Gulf States, and Egypt. Around 25 percent of the exported livestock comes from Darfur, after a sharp decline in Darfur’s export capacity due to conflict. Increased export sales have caused an increase in domestic livestock prices in all markets.

Rekindling and revitalizing chicken farming in Zambia

In Zambia, women play a major role in agriculture and constitute much of the labour force for cash crop production and home consumption. In Chilayabale area of Chongwe district in Zambia, a group of women founded Tuyumepo Women Cooperative with support from Zambia’s Farmer Input Support Program (FISP). Initially focused on commercial soya milk and okra coffee production, members shifted to poultry production in 2022, which they had identified as a game changer. They successfully developed a business plan that was funded by the World Food Programme, providing 150,000 Kwacha (USD 5,600) for broiler chicken production. Part of the funds were used to construct a poultry house and acquire 200-day-old chicks.

However, their excitement soon turned into despair. What had appeared a very profitable venture turned into a loss-making enterprise. The group could not understand why the birds, despite being provided with the required feed and vaccines, had a high mortality rate. They eventually abandoned the broiler production business.

Despite setbacks, the group’s determination remained strong. Like many other smallholder poultry producers in Zambia; they recognized the immense potential of chicken farming. But they were constrained by various production challenges such as limited access to improved chicken breeds or day-old chicks, limited access to key vaccines, basic chicken health services, quality feed, and essential extension services. These challenges led to poor productivity, high mortalities and underperformance of the enterprise and the chicken value chain in general.

However, a ray of hope emerged earlier this year with the arrival of the Southern Africa Accelerated Innovation Delivery Initiative – Livestock (AIDI-L) in Bimbe. A sensitization meeting organized by AIDI-L reignited their enthusiasm for poultry farming. What stood out was AIDI-L’s commitment not only to provide starter kits but also to offer training on best poultry farming practices. This renewed optimism prompted members of the Tuyumepo Women Cooperative, along with other farmers in the area, to attend training sessions on poultry production at Kambekete Camp, Chongwe District, Lusaka Province on 8 April 2024.

The participants were trained on general poultry production and marketing, and how to effectively train others on the same in the targeted districts. The target trainees were commercial poultry farmers, brooders, and lead farmers. Each training was attended by about 30 participants comprising lead farmers, brooders, and commercial poultry farmers in the district.

Led by Venture37, the International Livestock Research Institute (ILRI), and local government livestock officers, these sessions covered various aspects of poultry farming, from chicken health and housing to marketing and business development.

To many, the training was an eye-opener.

“I have just realized that our broilers were dying not because of diseases, but because of poorly ventilated housing structure,’ stated Annie, a brooder and a lead farmer in the area.”

With the newfound partnership, the cooperative plans to acquire 200 chicks.

Elizabeth Mwalusoke, a farmer from Lobolola Village, Chongwe District, had long recognized the potential of poultry farming but lacked the necessary knowledge and skills on good poultry husbandry, such as appropriate housing, hygiene, pests and diseases, and their control. She was lucky to have attended the AIDI-L sensitization meeting at Bimbe and Kambekete Camp in February 2024.

“This project will definitely help us develop our chicken business.”

The venture is even more appealing to Elizabeth, who owns two hectares of farmland, ideal for chicken rearing but not for large livestock farming.

For the ambitious Festus Nchenesi, the initiative provides opportunities for expanding and diversifying his commercial chicken enterprise. Nchenesi, a retired accountant, started with 100 broilers in 2017 at his one-hectare farm after relocating from Chongwe Town. He has steadily increased the flock to 300 birds but would have kept more if it had not been for the challenges he has encountered.

His attempts to venture into improved chicken farming failed due to a lack of knowledge of chicken brooding.

“I would have over 10 chicken brooding with at least 10 eggs each. But once one of the chickens had chicks, all the others would abandon their eggs and start fighting to care for the few hatched chicks. To circumvent this, I acquired a 32-egg capacity incubator, hoping not only to build my flock but also to brood and supply to other farmers in the area. However, the 6,000 Kwacha incubator could only hatch 3-5 eggs per incubation for reasons the supplier could not even explain. I am very optimistic that the project will turn my fortunes around. My target is to have at least 1,000 improved chickens because of their good marketability and returns and reduce the broiler flock.”

Others like retired Captain Ceasar Chibiye, a commercial poultry farmer in Kapiri District, Central Province, are more than ready to seize the market linkage opportunities that the project is bringing, being one of the major hurdles the farmers have been grappling with in the chicken value chain.

Laurence Ochieng, an ILRI veterinarian, was impressed with the enthusiasm and passion of the participants. He was optimistic that the project will greatly revitalise chicken farming in target regions.

“Most of the attendees seem to be involved in village chicken rearing.  For instance, those from Shamutinta village will benefit from disease control measures such as Newcastle disease vaccination as this seems to be their greatest challenge in rearing the birds to productive stage. Most of them had lost their flocks due to diseases, predominantly Newcastle and fowl pox.”

Esther Omosa, ILRI nutrition specialist, sensitized the participants on the importance human nutrition, promising to conduct a detailed TOT training on high impact nutrition sensitive interventions that need to be implemented at community level to prevent malnutrition.

Funded by the United States Agency for International Development, the two-year AIDI-L project aims to help 15,000 small-scale, poultry-keeping households acquire increased access dual-purpose backyard village chicks; and reduce morbidity and mortality of poultry byfacilitating access to, and vaccination of, poultry to key economically impactful diseases such as Newcastle Disease. With a holistic approach that addresses both production and market challenges, the project holds promise for revitalizing chicken farming in Zambia. Thousands more households will be reached through media advisories on the importance of vaccinations and improved husbandry practices for chickens.

LIPS-Zimbabwe empowers farmers through innovative intercropping trials

Written by mcallejas on . Posted in Blogs.

Since 2021, CIMMYT, in partnership with the International Livestock Research Institute (ILRI), the French Agricultural Research Centre for International Development (CIRAD), and the University of Zimbabwe’s Department of Veterinary, has been working in rural communities of Zimbabwe, as part of the Livestock Production Systems in Zimbabwe (LIPS-Zim) project. The activity is led by Zimbabwe’s Department of Research and Specialist Services and is at the forefront of introducing new agricultural innovations to local farmers.

One of their most impactful initiatives has been the intercropping trials involving maize and various legumes including jack bean, mucuna, lablab, and pigeon pea. This groundbreaking approach has not only transformed the lives of farmers but has also had a positive impact on the overall health of livestock.

Various leguminous fodder crops have been promoted widely as sources of high-quality protein feed in mixed crop-livestock systems of Zimbabwe. However, to diversify and increase the options for the drier regions, the LIPS-Zim project is testing new leguminous crops such as jack bean and pigeon pea, which are well-adapted to dry conditions.

Netsai Musekiwa, a farmer in the town of Mutoko, has been part of the LIPS-Zim project for the past two seasons, and is currently conducting intercrop trials with jack bean. “Since I started intercropping maize with jack bean, I have been amazed by the results and will continue on this path. The jack bean plants have shown strong tolerance to prolonged dry spells and heat stress,” she said. “Next season, I plan to extend my plot to harvest more jack bean.” These words of encouragement on intercropping maize with jack bean have also been largely echoed by many other farmers in Mutoko and Buhera during the feedback meetings held in October 2023.

What is intercropping and how beneficial is it to farmers?

Intercropping is an agricultural practice of growing two or more crops together on the same field simultaneously to maximize land use and enhance productivity. As different crops have different growth patterns and nutrient requirements, intercropping can help optimize resource utilization and boost overall crop output.

In addition, intercropping reduces the risk of climate induced crop failure as well as minimizing pest damage, enhances soil fertility by diversifying the root system, and can provide additional income streams to farmers.

The science behind jack bean and pigeon pea

Jack bean (canavalia ensiformis) and pigeon pea (cajanus cajan) are leguminous crops valued for their nitrogen-fixing abilities which aides in improving soil fertility. Both jack bean and pigeon pea have deep root systems, making them ideal candidates for the dry semi-arid conditions in Zimbabwe.

Pigeon pea is known for its drought-tolerance and produces edible seeds used in various culinary dishes and is a source of both food and feed. Jack bean is used as a forage crop for livestock, providing nutritious feed.

“Jack bean seeds contain a toxic compound called canavanine, which can be harmful when consumed in large quantities or not properly processed. To make jack beans safe for consumption, it must be boiled, soaked, or fermented,” said Isaiah Nyagumbo, cropping systems agronomist at CIMMYT. “We have introduced many farmers to the best practices for handling jack beans and have opened up new possibilities for its utilization in sustainable farming practices.”

While some farmers were intercropping with jack bean, others explored pigeon pea as an alternative. “I liked the intercropping of maize and pigeon pea on my plot. I am assured of getting nutritious food both for my family and livestock. After harvesting, I usually take the branches, then put them in the shade and dry them to retain the nutritional value. I occasionally give some to my goats during the dry season when feed from natural pastures is scarce, and my goat herd has risen to 12 goats,” said Fungai Kativu, a farmer in Mutoko.

Building capacity of local farmers

To narrow the knowledge gap and highlight the potential of such feed options, LIPS-Zim has also been spearheading the establishment of community level learning centers. These centers are a knowledge hub to local farmers, providing practical knowledge, facilitating the sharing of different perspectives while nurturing working as groups with a common vision. This “farmer learns by seeing” approach has been a success in the community.

Through this initiative, farmers have not only witnessed increased productivity but have also gained the necessary skills and knowledge to adapt to the changing agricultural landscape. “Intercropping leguminous crops with maize has shown great potential in improving food security and livestock feed production in Zimbabwe’s farming communities, especially in areas prone to heat and drought,” said Nyagumbo.

Strengthening farmer resilience through sustainable synergies between crops and livestock

Farmers, stakeholders, and partners, including seed companies, Hamara Chicks, PHI Commodities, the International Livestock Research Institute (ILRI), BioHUB Trust (BHT), Kurima Machinery and Technology, and Zimplow Limited, participated in the Seed and Livestock Fair in the Mbire and Murewa districts of Zimbabwe, which showcased indigenous and improved seed varieties and different technologies to strengthen crop and livestock value chain systems.

Initiated by CIMMYT in 2022, as the CGIAR Initiative on Agroecology, these series of fairs have become instrumental in bringing agrodealers closer to farmers and showcasing sustainable technologies and innovations that have the potential to strengthen production systems. It was also an opportunity for the agroecology initiative team to provide feedback to farmers and stakeholders on ongoing activities and technologies that were being tested since the initiative’s inception in Zimbabwe. By adopting a multi-partner approach, these fairs bring local food systems actors together to ensure food and nutrition security and improved income for farmers.

“The agroecology initiative has been collaborating with an array of organizations and institutes that can support our mission towards promoting agroecology and improving farming production, including other CGAIR entities like IWMI and ILRI, Hamara Group, Ecolyfe, and PHI Commodities,” said Dorcas Matangi, research associate at CIMMYT.

This year’s edition of the seed and livestock fair “Fostering Synergies: Diverse Crops, Livestock and Inclusive Communities” advocated for enhancing synergies within the farm to foster sustainable agroecology transitions for resilient food and nutrition outcomes. With over 800 farmers and stakeholders participating, the event provided a vibrant platform for knowledge sharing, exploration of indigenous and improved seed varieties, and sensitization of innovative technologies.

“The seed and livestock fairs hosted by the agroecology initiative bring together farmers and food system actors from all walks of life to foster learning around agroecology, which includes the importance of diversity (crop and livestock) while also appreciating local innovations in the respective area,” said Jesca Mapfinya, a Murewa farmer.

The right seed, assures a good harvest

Various seed companies participated in the fair to showcase different seeds which are well adapted in Murewa and Mbire districts.  Each agroecological region in Zimbabwe is unique, with adaptable seed varieties that are either landrace or improved. Local landraces and many underutilized crop species are adapted to weather and climate variability, climate change, and extreme weather such as drought and heat stress. Farmers indicated that their motivations for growing landraces are related to sustainable farming systems suitable for social, cultural, nutritional, and agronomic traits. Their place in rural communities remains important, providing much-needed functional diversity and social capital. Including improved varieties within the basket of options can further intensify production systems in these communities.

“Primarily, we sell seed varieties and build farmer capacity around appropriate agronomic practices. The seed fairs are a good platform to match seeds and systems and allows a farmer to provide feedback about our seed varieties and how they are performing in the respective areas,” said Onesmous Satenga, SeedCo.

Building crop and livestock synergies

For the first time since the inception of the fairs, livestock such as cattle, sheep, goats, chicken and rabbits were displayed. Partners, including ILRI and the Hamara Chicks, who are into sasso chicken and feed production, reiterated the importance of crop diversity for improved livestock nutrition. ILRI and the Grasslands Research Institute exhibited various local feedstocks and alternative livestock feed grasses and also presented several feed formulations. Farmers also provided feedback on the feeding strategies employed for different livestock.

“We feed cattle with poultry litter, maize grain, maize stover, and groundnut shells in various proportions depending on the availability of these feed sources. Forage legumes such as velvet bean (mucuna pruriens) and lablab (lablab purpureus) have been introduced, and we have started to grow these for feed,” said Samson Tashaya, Murewa farmer.

Of keen interest to farmers and stakeholders was the sasso breed of chickens that the Hamara Group was promoting.

“We have recently joined as partners with CIMMYT and are promoting hybrid chicken production, especially sasso, here in Murewa ward 27 and 4. This is our first time coming to this seed fair, and it was a learning opportunity. The interactions with farmers were really good,” said Alan Norton, team leader at Hamara Chicks.

Modernizing smallholder production systems

Mechanization experts from Kurima Machinery and Zimplow shared their recommendations at the fair. They acknowledged that farmers rely heavily on scarcely available labor and production activities that are backbreaking. They advocated for modern production systems to produce more food and support economic transformation. Experts from Kurima Machinery and Zimplow demonstrated several machines that could aid farmers in various on-farm activities.

“This fair has come at the right time as I begin land preparation for my pfumvudza (conservation agriculture plots). I have seen how the basin digger works, and I am keen to purchase an instrument to make my work much easier,” said Chief Chisunga, Mbire.

“This crop season’s outlook is still unclear, but weather experts have warned of an intense El Nino event likely to happen in the second half of the season. Technologies such as conservation agriculture can ensure good moisture retention in crop fields, and it needs to be paired with good agronomic practices,” said Tafadzwanashe Mabhaudhi, climate and food systems expert.

Farmers in Buhera gear up for climate-smart agriculture

As climate change effects intensify, new innovations that enable smallholder farmers to adapt are no longer an option but a necessity. Significant parts of Zimbabwe are semi-arid, receiving less than 600mm of rainfall per year. Smallholder farming communities in districts such as Buhera have embraced feed production and water conservation innovations deployed by the International Maize and Wheat Improvement Center (CIMMYT) as part of the Livestock Production Systems in Zimbabwe project (LIPS-Zim). The project, funded by the European Union and led by the International Livestock Research Institute (ILRI) and CIMMYT, champions the crop-related aspects of interventions and aims to increase livestock productivity in Zimbabwe’s semi-arid regions. The project specifically aims to promote increased adoption of climate-relevant innovations in livestock-based production systems and improved surveillance and control of livestock diseases. While focused on livestock, the project is based on the premise that the performance of the livestock sector depends heavily on crop husbandry. By the same token, the livestock sector has bi-products that directly impact the productivity of crops.

Zimbabwe is a country that is well suited to mixed farming systems. Most smallholder farmers have treated livestock and crop production as mutually exclusive, but the two enterprises can have a significant complementary effect on each other.

CIMMYT Cropping Systems Agronomist Isaiah Nyagumbo is leading the development of crop husbandry innovations aimed at increasing feed production that are poised to benefit smallholder farmers’ crop productivity and enhance the conditioning of livestock, especially cattle.

Despite extension recommendations for farmers not to grow maize in these regions, studies show that 60% of the arable land is still occupied by maize. This is due to maize’s popularity among farmers thanks to its diverse uses.

One solution is to support farmers with the most appropriate cultivars and most effective production technologies to help them be more resilient to climate change induced challenges. To contribute towards LIPS-Zim’s objective for increased feed production, CIMMYT scientists are testing and demonstrating the use of drought tolerant and nutritious maize varieties along with a wide range of leguminous species such as mucuna, dolichos lab-lab and cowpea, which are grown mostly as intercrops. Efforts are also being made to develop innovative water conservation options through reduced or no-till planting basins and tied ridging systems reinforced with different mulching options including conventional organic and synthetic artificial mulches. These are then being compared to traditional conventional mouldboard ploughing systems.

So far, the results are exciting and helping farmers to see the productivity gains from applying different technologies. Mr. and Mrs. Nyekete, smallholder farmers who volunteered to work with CIMMYT on these innovations, are optimistic about widespread adoption once the trials are concluded as the technologies can suit different levels of investment by farmers.

“We have a lot of farmers visiting us as they observe a diversity of technologies on our plot. The artificial mulch concept is one which is very new, and farmers are curious as to how it works. They can observe for themselves that, especially when used with tied ridges, it is very effective in retaining moisture,” said Mr and Mrs Nyekete.

“The same applies to organic mulch. Government extension workers have, over the years, been encouraging us to plant our maize under the Pfumvudza conservation agriculture model, and in it is the use of organic materials as mulch. The level of compliance in areas such as Buhera has been low, where people practice Pfumvudza without fully applying all the principles, especially soil cover. The water conservation trials are providing evidence that when one dedicates themselves to mulching their crop, whether using organic or synthetic mulches, the maize productivity is comparatively higher. As you can see, the maize plots with these water harvesting technologies are showing high vegetative growth in comparison to conventionally planted maize.”

Over the years, there has been a slow adoption of new innovations emanating from scientific research usually conducted on research stations. The use of on-farm research trials and demonstrations helps smallholder farmers to participate in the research process and co-create technologies, which shortens the adoption period and stimulates adoption at scale. This approach enables more farmers, who are not hosts, to benefit from the technologies showcased in the trials and to observe and learn from the trials. As the saying goes, “seeing is believing” and farmers can choose the options most relevant to their own circumstances.  As such, farmers can conclude for themselves which technologies bear results compelling enough for them to adopt.

Despite the artificial mulching technology demonstrating impressive results so far, Nyagumbo cautions that before the technology can be promoted at scale, more research, as well as proof of concept for these systems are needed.

“Firstly, we see that the quality of the material used has a big bearing on the ability to reduce evaporation from the soil. Secondly, some farmers have observed germination challenges due to the synthetic materials creating an attractive habitat for rodents that eat the maize seed before it germinates. Thirdly, the returns from such investments need to be justified by highly attractive economic returns arising from high yields that will also enable farmers to intensify their production systems by producing their food needs from much smaller areas. Further studies and analyses therefore need to be conducted,” said Nyagumbo.

“Furthermore, so far the idea of tied ridging combined with organic mulches also seems to offer a highly attractive option for farmers that will contribute to increased feed productivity from the enhanced grain and crop residues, since increased biomass output also means increased livestock feed availability.”

While breeding excellence is proving to be an effective method for responding to climate change through improved seed varieties and high-performance livestock breeds, new crop and livestock production technologies are required to complement the genetic gains from breeding. The crop production technologies being showcased in in Buhera along with drought tolerant and nutritious maize varieties and legumes, promise to be transformative for semi-arid regions for both crop and livestock systems.

Identifying climate mitigation strategies from AFOLU sector in Mexico

Written by Sarah McLaughlin on . Posted in Publications.

The vital tasks for each country to reduce its greenhouse gas (GHG) emissions and limited carbon outputs are daunting, especially with 2030 deadlines imposed by the Paris Climate Agreement only eight years away. National stakeholders would benefit greatly from roadmaps that identify realistic and achievable milestones to point the way forward.

Researchers at the International Maize and Wheat Improvement Center (CIMMYT) have provided just such a road map. Using easily available data, they developed rapid assessment methods and adoption costs for mitigation related to crops, livestock, and forestry to identify priority locations and actions. Their article, “Quantification of economically feasible mitigation potential from agriculture, forestry and other land uses in Mexico”, was published in Carbon Management.

Applying these methods for Mexico, researchers found a national mitigation potential of 87.88 million metric tons (Mt) of carbon dioxide equivalents per year.

“Faced with such an overwhelming issue like climate change, it can be difficult for an individual, an organization, and especially an entire nation to know where to start. We developed a rapid assessment framework, tested in India, Bangladesh, and Mexico, but we believe other nations can use our methods as well,” said Tek Sapkota, the project leader and first author of the paper.

The research specifically focused on climate change mitigation in agriculture, forestry, and other land uses (AFOLU). Agriculture and related land use change contributed about 23% of the world’s anthropogenic GHG emissions in 2016, and that number is expected to increase as more food needs to be produced for the world’s growing population.

The researchers’ starting point was to quantify baseline emissions and analyze the major sources of emissions. Mexico’s AFOLU sector is responsible for 14.5% of its total national GHG emissions. In Mexico’s agricultural sector, methane and nitrous oxide emissions arise from livestock activities (enteric fermentation and fertilizers), as well as from agricultural activities (soil management and field burning of crop residues). For land use, carbon dioxide emissions and removals result from changes in forest lands, pastures, agricultural land, wetlands, and settlements.

Activities identified for GHG mitigation in crop production included avoiding fertilizer subsidies, since those tend reward inefficient nitrogen use. Subsidies could be of use, however, in encouraging farmers to adopt more efficient nitrogen management. Precision levelling of crop fields can help to lower GHG emissions by reducing cultivation time and improving the efficiency of fertilizer and irrigation water and adoption of conservation agriculture practices, such as zero tillage.

“Adoptions of these practices will not only reduce GHG emissions, but they will also help increase productivity,” said Ivan Ortiz-Monasterio, co-author and Mexico coordinator of the study.

In the livestock sector, mitigation possibilities identified are the creation of official programs, financial support, and capacity building on composting and biodigester. In FOLU sector, researchers identified options such as zero deforestation and C offset in the C market.

In addition to mapping out the mitigation benefits of specific activities, researchers also considered the costs associated with implementing those activities. “Looking at these efforts together with the cost of their implementation provide a complete picture to the implementing bodies to identify and prioritize their mitigation efforts consistent with their development goals,” said Sapkota. For example, some efforts, like increasing nitrogen use efficiency, do not provide the most climate benefits but are relatively inexpensive to realize, while establishing and maintaining carbon capture markets provides large reductions in GHG, they can be expensive to implement.

Researchers examined publicly available AFLOU spatial data for each Mexican state. At the state level, AFOLU mitigation potentials were highest in Chiapas (13 Mt CO2eq) followed by Campeche (8Mt CO2eq), indicating these states can be considered the highest priority for alleviation efforts. They identified an additional 11 states (Oaxaca, Quintana Roo, Yucatan, Jalisco, Sonora, Veracruz, Durango, Chihuahua, Puebla, Michoacán, and Guerrero) as medium priorities with mitigation potentials of 2.5 to 6.5 Mt CO2eq.

“Our data driven, and evidence-based results can help the government of Mexico refine its national GHG inventory and its Nationally Determined Contributions target and monitor progress,” said Eva Wollenberg, the overall coordinator of the study and research professor of University of Vermont, USA. “This analysis further provides an example of a methodology and results to help inform future efforts in other countries in addition to Mexico.”

New solutions for chopping fodder

Written by Emma Orchardson on . Posted in Features.

It is a laborious and time-consuming process: chopping plant matter by hand to feed to livestock. In Cox’s Bazar district, in eastern Bangladesh, it is common practice. A mechanized fodder chopper can do the job more quickly and efficiently — yet this simple but effective machine has not seen much use in the region.

To address this, a collaboration between the International Maize and Wheat Improvement Center (CIMMYT) and aid organizations in the region is creating networks between farmers, agriculture service providers and the businesses that make and distribute the machines.

The Cox’s Bazar region is host to around 900,000 Rohingya refugees who were displaced from Myanmar. The influx of refugees has put a strain on resources in the region. This collaborative effort took place near the camps, in an effort to support capacity and economic development in the host communities nearby.

Though this collaboration has only been around for a few months, it has already seen early success, and received an award from the United States Agency for International Development (USAID). The award recognized the organizations’ “outstanding collaboration that contributed to increased and efficient livestock production through mechanization in the host communities impacted by the influx of Rohingya refugees.”

Mechanization and livestock collaboration

The project — funded by USAID — is a partnership between two existing efforts.

The first is Cereal Systems Initiative for South Asia – Mechanization Extension Activity (CSISA-MEA), which aims to boost the country’s private agricultural machinery industry while supporting local farmers. This initiative supports the mechanization of agriculture in Bangladesh, through increased capacity of the private sector to develop, manufacture and market innovative new technologies. CSISA-MEA is implemented by the International Maize and Wheat Improvement center (CIMMYT) in partnership with iDE and Georgia Institute of Technology.

The second is the Livestock Production for Improved Nutrition (LPIN) Activity, which works to improve nutrition and income generation among rural households in the region.

“We made a great collaboration with LPIN,” said Jotirmoy Mazumdar, an agriculturalist working with CSISA-MEA. “We’re very happy that our initiative helped us achieve this award. In this short time period, a new market opportunity was created.”

Nonstop chop

There are numerous benefits to using fodder choppers, according to Muhammad Nurul Amin Siddiquee, chief of party of LPIN. For one, having access to the choppers can save farmers around $7 (600 Bangladeshi taka) in labor costs per day, and reduce the amount of feed wasted by 10–15%. On average, a farmer can hand-chop 500 kg of forage or fodder each day, while the machines can process around 1,000 kg of the material per hour.

According to Siddiquee, giving chopped feed to livestock improves their productivity. One farmer’s herd of 17 crossbreed cows produced 115 liters of milk per day — he expects this to increase to 130 liters per day after feeding them fodder produced with a mechanized chopper.

“He can now save labor costs and four hours of his time per day by using the fodder chopping solutions,” he said, adding that the collaborative effort is “fostering increased livestock productivity and [farmer] incomes.”

However, Cox’s Bazar is far away from the center of Bangladesh, where most of these machines are produced. For example, there are more than 30 small engineering workshops in the more centrally located Khulna Division and they have cumulatively made 7,470 choppers.

“In Cox’s Bazar, it was almost impossible for those livestock farmers to get to know the chopper machines, and actually get access to them,” said Khaled Khan, team lead with iDE, who also aided in private-sector engagement.

So, the collaboration between CSISA-MEA and LPIN began connecting farmers and agriculture service providers with these fodder chopper producers and distributors. Moreover, it worked to increase knowledge of how to operate the machines among the farmers.

“Fodder choppers are an entirely new technology in Cox’s Bazar,” said Zakaria Hasan, CSISA team lead in the district.

Though it is still early days, the partnership has been met with a warm reception. Farmers and agriculture service providers cumulatively purchased 12 of the choppers within two weeks — each machine can support its owner and five other farmers — and three dealers are now selling the machines to meet farmer demand. In the region, 60 dairy farms are now purchasing chopped fodder for their livestock.

According to Khan, engaging the private sector in this project was essential. He explained that increasing the connectivity between the buyers and the sellers will help make the market larger and more stable.

“We found the perfect opportunity of supply and demand because their partners are demanding our partners’ service. The role of the private sector was the most important for the sustainability of this marriage of demand and supply,” Khan said.

“We want to establish a linkage between these two private entities. Our project’s job is to facilitate that, so that even after the project is over this networking continues in the future.”

A number of readily-available farming methods could allow Bangladesh’s agriculture sector to decrease its greenhouse gas emissions while increasing productivity, according to a new study by the International Maize and Wheat Improvement Center (CIMMYT) and partners.

The study, published in Science of the Total Environment, measured the country’s emissions due to agriculture, and identified and analyzed potential mitigation measures in crop and livestock farming. Pursuing these tactics could be a win-win for farmers and the climate, and the country’s government should encourage their adoption, the research suggests.

“Estimating the greenhouse gas emissions associated with agricultural production processes — complemented with identifying cost-effective abatement measures, quantifying the mitigation scope of such measures, and developing relevant policy recommendations — helps prioritize mitigation work consistent with the country’s food production and mitigation goals,” said CIMMYT climate scientist Tek Sapkota, who led this work.

To determine Bangladesh’s agricultural greenhouse gas emissions, the researchers analyzed 16,413 and 12,548 datapoints from crops and livestock, respectively, together with associated soil and climatic information. The paper also breaks down the emissions data region by region within the country. This could help Bangladesh’s government prioritize mitigation efforts in the places where they will be the most cost-effective.

“I believe that the scientific information, messages and knowledge generated from this study will be helpful in formulating and implementing the National Adaptation Plan (NAP) process in Bangladesh, the National Action Plan for Reducing Short-Lived Climate Pollutants (SLCPs) and Nationally Determined Contributions (NDC),” said Nathu Ram Sarker, director general of the Bangladesh Livestock Research Institute.

Policy implications

Agriculture in Bangladesh is heavily intensified, as the country produces up to three rice crops in a single year. Bangladesh also has the seventh highest livestock density in the world. In all, the greenhouse gas output of agriculture in Bangladesh was 76.79 million metric tons of carbon dioxide equivalent (Mt CO2e) in 2014-15, according to the research. This emission is equivalent to the emission from fossil fuel burning by 28 million cars for a year.  At the going rate, total agricultural emission from Bangladesh are expected to reach 86.87 Mt CO2e by 2030, and 100.44 Mt CO2e by 2050.

By deploying targeted and often readily-available methods, Bangladesh could mitigate 9.51 Mt and 14.21 Mt CO2e from its agriculture sector by 2030 and 2050, respectively, according to the paper. Further, the country can reach three-fourths of these outcomes by using mitigation strategies that also cut costs, a boon for smaller agricultural operations.

Adopting these mitigation strategies can reduce the country’s carbon emissions while contributing to food security and climate resilience in the future. However, realizing the estimated potential emission reductions may require support from the country’s government.

“Although Bangladesh has a primary and justified priority on climate change adaptation, mitigation is also an important national priority. This work will help governmental policy makers to identify and implement effective responses for greenhouse gas mitigation from the agricultural sector, with appropriate extension programs to aid in facilitating adoption by crop and livestock farmers,” said Timothy Krupnik, CIMMYT country representative in Bangladesh and coauthor of the paper.

Mitigation strategies

The research focused on eight crops and four livestock species that make up the vast majority of agriculture in Bangladesh. The crops — potato, wheat, jute, maize, lentils and three different types of rice — collectively cover more than 90% of cultivated land in the nation. Between 64 and 84% of total fertilizer used in Bangladesh is used to cultivate these crops. The paper also focuses on the four major kinds of livestock species in the country: cattle, buffalo, sheep and goats.

For crops, examples of mitigation strategies include alternate wetting and drying in rice (intermittently irrigating and draining rice fields, rather than having them continuously flooded) and improved nutrient use efficiency, particularly for nitrogen. The research shows that better nitrogen management could contribute 60-65% of the total mitigation potential from Bangladesh’s agricultural sector. Other options include adopting strip-tillage and using short duration rice varieties.

For livestock, mitigation strategies include using green fodder supplements, increased concentrate feeding and improved forage/diet management for ruminants. Improved manure storage, separation and aeration is another potential tool to reduce greenhouse gas emissions. The mitigation options for livestock would make up 22 and 28% of the total potential emission reductions in the sector by 2030 and 2050, respectively.
