CIMMYT trains next generation of scientists to tackle soil-borne pathogens

Written by Alison Doody on . Posted in News.

Two new students have graduated from the International Maize and Wheat Improvement Center’s (CIMMYT’s) Soil-Borne Pathogens program. The two new graduates, Khawla Mehalaine and Salah-Eddine Laasli, were supervised by CIMMYT senior scientist Abdelfattah Dababat.

He leads the Soil-Borne Pathogens program, which focuses on identifying the main soil-borne pathogens associated with cereals and developing an integrated pest management approach to combat them. The research team is particularly interested in finding novel sources of resistance against these pathogens.

Over the last two decades, CIMMYT scientists leading the Soil-Borne Pathogens program have trained tens of students which constitute the next generation of top researchers on this topic. Through this program, CIMMYT has also organized workshops and courses in North Africa, including a symposium on cereal nematodes held in Agadir, Morocco, in 2017.

Since soil-borne pathogens are exacerbated by water stress conditions, researchers have identified the Central and West Asia and North Africa regions as priority areas, due to their vulnerability to drought.

On March 1, 2021, Syngenta, in collaboration with CIMMYT and other partners, led the first One Earth Soil and Root Health Forum, an event which examined the importance of root and soil health to food security, climate resilience and livelihoods. The event also created a community for action on root and soil health.

Nematodes in Algeria

Mehalaine holds an engineering degree in agronomy and a master’s degree in plant protection from the Higher National School of Agronomy (ENSA) in Algeria. She successfully defended her PhD dissertation “Studies of cereal cyst nematodes of the genus Heterodera in the regions of northern Algeria” in June 2021, graduating from ENSA with honors.

She studied the behavior of four durum wheat varieties against cereal cyst nematodes through field surveys, molecular identification at species levels, and by evaluating the yield components of these wheat varieties.

She was promoted by ENSA professor Hammach M. and supervised by Dababat from CIMMYT, and professors Mustafa Imren and Göksel Özer from Abant Izzet Baysal University in Turkey.

“Completing my doctorate was a truly enriching experience and a challenging but rewarding journey,” Mehalaine said. “It was a collective effort and I am extremely grateful to Dr Abdelfattah Dababat for sharing his scientific skills, for his patience and support, and for all the opportunities I was given to further my research. Thanks to him, I got to know the world of nematodes. Special thanks to CIMMYT for funding the molecular study part.”

Root-lesion nematode and crown rot fungi

Laasli graduated with an International Master of Agronomic and Environmental Nematology (IMANEMA) from Ghent University, in collaboration with CIMMYT, the National Institute of Agricultural Research in Morocco and the Faculty of Agriculture at Abant Izzet Baysal University in Turkey.

His master thesis, entitled “Interaction of Root-Lesion Nematode (Pratylenchus thornei) and Crown Rot fungi (Fusarium culmorum) associated with wheat resistance under simulated field conditions,” was promoted by Wim Bert, a professor at the University of Ghent, and Dababat. The project was also supervised by Imren and Özer.

Laasli evaluated the host status of 150 spring wheat lines to both P. thornei and F. culmorum, and estimated the damage caused by the disease complex involving both pathogens at different infection scenarios. He found several lines that possessed multiple resistance to both diseases tested — which could be powerful sources of resistance for breeding program worldwide.

The Association of Mexican Seed Producers (Asociación Mexicana de Semilleros, A.C., or AMSAC) gave the International Maize and Wheat Improvement Center (CIMMYT) its annual Cesár Garza Award for work by MasAgro (Crops for Mexico), a project that develops and spreads high-yielding, climate resilient maize and improved farming practices in Mexico. MasAgro is operated by CIMMYT and Mexico’s Secretariat of Agriculture and Rural Development (SADER).

“We unanimously selected CIMMYT for having established an effective and inclusive network of some 100 Mexican testing sites to generate and spread hybrid seed adapted to the country’s diverse agro-ecologies,” said José Luis Gastelum Careaga, president of the governing council of AMSAC, a group of more than 70 seed companies.

The award ceremony took place in Playa del Carmen, in Mexico’s Quintano Roo state, on November 4, 2021.

CIMMYT breeding research is behind the development of 70 new maize hybrids released in Mexico by dozens of small- and intermediate-scale seed companies, helping to double the maize yields of farmers who adopt them, according to Bram Govaerts, CIMMYT director general and leader of the Center’s work in MasAgro.

“AMSAC’s recognition comes at a crucial time, when public support for crop breeding, seed systems, and capacity building are more urgent than ever in the face of climate change and increased, pandemic-related food insecurity,” Govaerts said. “We’ll leverage this prestigious award and our strong partnership with AMSAC members to move toward an improved and more widespread version of MasAgro’s integrated approach for transforming Mexico’s cereal crop farming systems.”

Taking advantage of CIMMYT training and breeding lines, Mexican seed producers working with MasAgro have boosted their maize seed sales 33% — or 4.6% yearly — during 2011–20, Govaerts said.

This and the recent award illustrate CIMMYT’s success at sharing improved maize through powerful, decades-long partnerships with public and private entities. Small- and medium-scale seed companies have benefitted from access to CIMMYT breeding lines, technical support, business model training, and Center participation in efforts to foster competitive seed markets, according to a recently published book documenting 50 years of maize research by CIMMYT and the International Institute of Tropical Agriculture (IITA). Both centers are members of CGIAR, the world’s largest global agricultural innovation network.

“The increased number and market share of [small- and medium-scale] maize seed companies in Mexico and sub-Saharan Africa in recent years are strongly linked to the availability of stable, stress tolerant inbreds from CGIAR programs,” the book’s executive summary states. “The annual production … of over 130,000 tons of seed of CGIAR-derived stress-tolerant hybrids in Africa by [small- and medium-scale enterprises] … has addressed an important gap in seed markets not being met by multi-national companies.”

In 2015 more than a third of the area in sub-Saharan Africa was sown to new varieties and hybrids derived from CIMMYT and IITA breeding research, and adoption has accelerated since then, generating from $0.66 to 1.05 billion each year in economic benefits, according to a 2021 study.

As part of CIMMYT partnerships with large, multi-national seed companies, the Center has obtained royalty-free licenses to use proprietary technology and maize hybrids in specific areas of Africa, focusing on small-scale farmers. These partnerships, as well as similar agreements with advanced public research institutes, have fostered more widespread application for tropical maize of tools such as genomic selection, database software, and doubled haploids.

In Asia, building on collaborations from as far back as the 1960s, CIMMYT launched a maize improvement consortium in 2010 involving 25 mostly small- and medium-scale seed companies. For a modest annual fee to fund consortium management, members have access to early- and advanced-generation CIMMYT inbred lines and trait donors, as well as support services for hybrid development. This model has subsequently been copied in Mexico and in eastern and southern Africa (17 companies).

“CIMMYT science and support for maize and wheat farming systems span more than six decades and have brought impressive, well documented impacts in improved harvests and food security for those who grow and consume these globally-critical staple crops,” Govaerts said. “On behalf of the Center, I would like to recognize and thank those who fund our work, and especially the hundreds of skilled and committed partners without whom our efforts would not be possible.”

2021 GAP Report endorses CIMMYT’s integrated agri-food systems methodology

Written by Ricardo Curiel on . Posted in News.

The 2021 Global Agricultural Productivity (GAP) Report warns that farmers and food workers globally face the intimidating challenge of producing food sustainably in a degrading environment. The global economic slowdown and climate change are making the situation even more difficult.

This year’s report, titled Strengthening the Climate for Sustainable Agricultural Growth, argues that “accelerating productivity growth at all scales of production is imperative to meet the needs of consumers and address current and future threats to human and environmental well-being.”

The report, produced by Virginia Tech, was presented at the 2021 Borlaug Dialogue, part of the World Food Prize events.

The International Maize and Wheat Improvement Center’s (CIMMYT) public–private partnership model for the Integrated Agri-food Systems Initiative (IASI) contributes to one of six key strategies that accelerate productivity growth, according to the 2021 GAP Report.

“Our integrated methodology engages farmers in participatory research and innovation efforts, effectively improving small-scale systems,” said Bram Govaerts, director general of CIMMYT. “This results-backed strategy bridges yield gaps and builds resilience to the effects of climate change, with the main objective of giving access to enhanced nutrition and new market opportunities.”

The skillset and cumulative knowledge of small farmers worldwide shapes CIMMYT’s integrated development projects.

“The Integrated Agri-food Systems Initiative (IASI) is designed to generate strategies, actions and quantitative, Sustainable-Development-Goals-aligned targets that have a significant livelihood of supportive public and private investment,” concludes the GAP Report.

The report argues that technology itself does not boost productivity and resilience. Instead, “partnerships play an important role in enhancing human capital: a set of skills and knowledge by producers and others in the agricultural value chain are essential in a time of pandemics.”

A decade of world-leading maize and wheat research

Written by Bea Ciordia on . Posted in Features.

For over a decade, the CGIAR Research Programs on Maize (MAIZE) and Wheat (WHEAT) have been at the forefront of research-for-development benefiting maize and wheat farmers in the Global South, especially those most vulnerable to the shocks of a changing climate.

From 2012 to 2021, MAIZE has focused on doubling maize productivity and increasing incomes and livelihood opportunities from sustainable maize-based farming systems. Through MAIZE, scientists released over 650 elite, high-yielding maize varieties stacked with climate adaptive, nutrition enhancing, and pest and disease resistant traits.

The WHEAT program has worked to improve sustainable production and incomes for wheat farmers, especially smallholders, through collaboration, cutting-edge science and field-level research. Jointly with partners, WHEAT scientists released 880 high-yielding, disease- and pest-resistant, climate-resilient and nutritious varieties in 59 countries over the life of the program.

To document and share this legacy, the MAIZE and WHEAT websites have been redesigned to highlight the accomplishments of the programs and to capture their impact across the five main CGIAR Impact Areas: nutrition, poverty, gender, climate and the environment.

We invite you to visit these visually rich, sites to view the global impact of MAIZE and WHEAT, and how this essential work will continue in the future.

A visual celebration in Mexico City

CIMMYT’s relationship with Mexico is one of a kind: in addition to being the birthplace of the wheat innovations that led to the Green Revolution and the founding of CGIAR, Mexico is also where maize originated thousands of years ago, becoming an emblem of the country’s economy and identity.

Honoring this longstanding connection and celebrating Mexico’s key contribution to global wheat and maize production, Mexico City will host a photo exhibition from December 1, 2021, to January 15, 2022, in the Open Galleries Lateral, located on Paseo de la Reforma, one of city’s most iconic promenades.

Titled “Maize and Wheat Research in Focus: Celebrating a Decade of Research for Sustainable Agricultural Development Under the CGIAR Research Programs on Maize and Wheat,” the exhibition illustrates the impact of MAIZE and WHEAT over the last ten years. The selection of photographs documents the challenges faced by maize and wheat smallholders in different regions, and showcases innovative interventions made by national and regional stakeholders worldwide.

From pathbreaking breeding research on climate-smart varieties to helping farming families raise their incomes, the photos — taken by CGIAR photographers before the COVID-19 pandemic — capture both the breadth of the challenges facing our global agri-food systems and the spirit of innovation and cooperation to meet them head on.

Don’t miss the chance to visit the exhibition if you are in Mexico City!

Science, technology and farmers, the three pillars of CIMMYT at COP26

Written by Bea Ciordia on . Posted in Features.

From October 31 to November 12, all eyes and cameras turned to Glasgow, where the 26th Conference of the Parties of the United Nations Convention against Climate Change (COP26) took place in a hybrid format. With temperatures rising around the world and extreme weather events becoming increasingly frequent, country leaders and climate experts came together in Scotland to discuss the next steps in the fight against climate change.

Together with other CGIAR Centers, the International Maize and Wheat Improvement Center (CIMMYT) took part in this crucial conversation, drawing attention to the impact of climate change on smallholder agriculture and echoing CGIAR’s call for increased funding for agricultural research and innovation.

Here’s a summary of the events in which CIMMYT researchers and scientists participated.

“Because farmers feed us all: using climate for a resilient food system”

November 6, 2021

Sponsored by the UK Met Office, this event focused on the effects of climate change on the resilience of food systems and how this impact is factored into decision-making. Speakers discussed the real-life application of climate risk information, highlighting the importance of global collaboration and multi-stakeholder partnerships in developing context-specific climate services.

Focusing on CIMMYT’s work in Ethiopia, research associate Yoseph Alemayehu and senior scientist Dave Hodson provided some insights on the wheat rust early warning system. This revolutionary mechanism developed by CIMMYT and partners helps farmers in developing countries predict this disease up to a week in advance.

“COP26 highlighted the vulnerability of different agriculture sectors to climate change, including increased threats from pests and pathogens. From the work in Ethiopia on wheat rust early warning systems, strong partnerships and the application of advanced climate science can play an important role in mitigating some of the effects.” – Dave Hodson

“Developing Climate Resilient Food Systems Pathways: Approaches From Sub-Saharan Africa”

November 8, 2021

Putting an emphasis on participatory governance and community-centered technologies, this event showcased innovative approaches to strengthen the resilience of African food systems, calling for increased investment in the scale-up of climate-smart agriculture practices to meet growing demand.

Joining from Zimbabwe, Christian Thierfelder, Principal Cropping Systems Agronomist gave an overview of CIMMYT’s work in southern Africa, explaining how the introduction of conservation agriculture back in 2004 helped farmers overcome low crop yields and boost their incomes.

“If one thing was made clear at COP26, it is the urgent need for a change in the way we do agriculture. The status quo is not an option and we, as CIMMYT and part of the One CGIAR, will continue to generate the scientific evidence and climate-smart solutions to accelerate this change and address the climate challenges ahead of us, with farmers at the core of our work.” – Christian Thierfelder

“4 per 1000” Initiative Day

November 10, 2021

The “4 per 1000” Initiative, a multi-stakeholder partnership of more than 650 members on food security and climate change, held a day-long hybrid event to explore how healthy soils can help agriculture and forestry adapt to and mitigate climate change.

At the Partner Forum, Bram Govaerts, Director General of CIMMYT, stressed the urgent need to fund soil science to achieve its carbon sequestration potential, reiterating CIMMYT’s commitment to supporting this science with results-oriented actions that scale out sustainable practices and technologies.

“For me, the main take-away of the summit is the growing consensus and understanding that we need to transform agriculture and food systems to achieve global emissions targets on time.” – Bram Govaerts

Harnessing the power of science to reduce poverty and malnutrition

A five-year partnership being launched by the Innovative Genomics Institute (IGI)—a non-profit founded by Nobel Laureate Jennifer Doudna—and CGIAR, the world’s largest publicly-funded agricultural research partnership, will harness the power of science to help millions of people overcome poverty, hunger and malnutrition.

One in four people globally, and rising, are unable to afford a healthy diet. COVID-19 has exacerbated this trend by disrupting food production and distribution, driving up by 20 percent the number of people threatened by hunger in 2020. The pandemic is unfolding amidst an environmental and climate crisis which is undermining food production and our ability to nourish the world.

But global consensus is building for urgent action. At the COP26 meetings in November, 45 nations committed to shifting to more sustainable ways of farming and accelerate the deployment of green innovations. Similarly, in late September, many government representatives at the United Nations Food Systems Summit committed to accelerating the transformation of how we grow, transport, process, and consume food. Recognizing the centrality of science and innovation for driving that transformation, United Nations Secretary-General António Guterres called on the world to scale public and private investment in research for food.

According to Barbara Wells, Global Director for Genetic Innovation at CGIAR: “World-class science is vital for facilitating farmer adaptation and mitigating our food system’s contribution to climate change. Plant-breeding innovations can help ramp up food production while making farms more climate resilient, profitable and environmentally friendly”.

“Technologies such as gene editing, which enable scientists to make targeted changes to a crop’s DNA, can accelerate the development of more disease-resistant, water-efficient varieties that can improve food production and nutrition in areas that are especially vulnerable to climate change,” Dr. Wells explained.

CGIAR has produced and promoted innovations that are boosting the sustainable production of nutritious food in Africa, Asia and Latin America. Over the past five decades, CGIAR scientists and national partners have developed and disseminated robust and highly productive crop varieties and livestock breeds tailored to the needs of local men and women. Those innovations have helped hundreds of millions of people across the Global South overcome hunger and poverty.

The IGI is a collaboration of the University of California, Berkeley and the University of California, San Francisco with a mission to develop revolutionary genome-editing tools that enable affordable and accessible solutions in human health, climate, and agriculture. The IGI’s Climate & Sustainable Agriculture program focuses on developing crops that are resistant to pests and diseases, resilient to a changing climate, and less dependent on farmer inputs. Whereas the IGI is a pioneer in applied genomic research, CGIAR focuses on translating discoveries into improved crop varieties and cropping systems. This partnership provides an accelerated pipeline from upstream innovation to real-world impact.

“The IGI is testing technologies with great potential to benefit people in the countries where CGIAR is active, such as a way of removing the cyanide found in cassava—a staple upon which nearly a billion people depend—and fighting diseases in economically important crops like wheat, rice and bananas,” said Brian Staskawicz, the IGI Director of Sustainable Agriculture.

“The IGI is also pioneering new ways to reduce methane emissions from rice farming, which accounts for 2.5 percent of humanity’s contribution to global warming, by using genomic approaches to reduce methane production by soil microbes,” he added.

“By partnering with CGIAR, the IGI can ensure that the products of its research will benefit farmers and consumers in some of the world’s poorest countries, where CGIAR has been working for 50 years and has extensive partner networks,” said Dr. Melinda Kliegman, Director of Public Impact at the IGI. “Together we can accelerate the development and delivery of more climate-resilient, productive and nutritious crops for resource-poor farmers and consumers.”

Over the next five years, the IGI and CGIAR will use the latest breakthroughs in genomic science to enhance the resilience and productivity of farmers in low- and middle-income countries and improve the wellbeing and livelihoods of women and men in some of the world’s poorest communities.

Bringing wild wheat’s untapped diversity into elite lines

Written by Rodrigo Ordóñez on . Posted in Features.

A collaboration involving 15 international institutes across eight countries has optimized efforts to introduce beneficial traits from wild wheat accessions in genebanks into existing wheat varieties.

The findings, published in Nature Food, extend many potential benefits to national breeding programs, including improved wheat varieties better equipped to thrive in changing environmental conditions. This research was led by Sukhwinder Singh of the International Maize and Wheat Improvement Center (CIMMYT) as part of the Seeds of Discovery project.

Since the advent of modern crop improvement practices, there has been a bottleneck of genetic diversity, because many national wheat breeding programs use the same varieties in their crossing program as their “elite” source. This practice decreases genetic diversity, putting more areas of wheat at risk to pathogens and environmental stressors, now being exacerbated by a changing climate. As the global population grows, shocks to the world’s wheat supply result in more widespread dire consequences.

The research team hypothesized that many wheat accessions in genebanks — groups of related plant material from a single species collected at one time from a specific location — feature useful traits for national breeding programs to employ in their efforts to diversify their breeding programs.

“Genebanks hold many diverse accessions of wheat landraces and wild species with beneficial traits, but until recently the entire scope of diversity has never been explored and thousands of accessions have been sitting on the shelves. Our research targets beneficial traits in these varieties through genome mapping and then we can deliver them to breeding programs around the world,” Singh said.

Currently adopted approaches to introduce external beneficial genes into breeding programs’ elite cultivars take a substantial amount of time and money. “Breeding wheat from a national perspective is a race against pathogens and other abiotic threats,” said Deepmala Sehgal, co-author and wheat geneticist in the Global Wheat program at CIMMYT. “Any decrease in the time to test and release a variety has a huge positive impact on breeding programs.”

Taking into genetic biodiversity

The findings build from research undertaken through the Seeds of Discovery project, which genetically characterized nearly 80,000 samples of wheat from the seed banks of CIMMYT and the International Center for Agricultural Research in the Dry Areas (ICARDA).

First, the team undertook a large meta-survey of genetic resources from wild wheat varieties held in genebanks to create a catalog of improved traits.

“Our genetic mapping,” Singh said, “identifies beneficial traits so breeding programs don’t have to go looking through the proverbial needle in the haystack. Because of the collaborative effort of the research team, we could examine a far greater number of genomes than a single breeding program could.”

Next, the team developed a strategic three-way crossing method among 366 genebank accessions and the best historical elite varieties to reduce the time between the original introduction and deployment of an improved variety.

Worldwide impact

National breeding programs can use the diverse array of germplasm for making new crosses or can evaluate the germplasm in yield trials in their own environments.

The diverse new germplasm is being tested in major wheat producing areas, including India, Kenya, Mexico and Pakistan. In Mexico, many of the lines showed increased resistance to abiotic stresses; many lines tested in Pakistan exhibited increased disease resistance; and in India, many tested lines are now part of the national cultivar release system. Overall, national breeding programs have adopted 95 lines for their targeted breeding programs and seven lines are currently undergoing varietal trials.

“This is the first effort of its kind where large-scale pre-breeding efforts have not only enhanced the understanding of exotic genome footprints in bread wheat but also provided practical solutions to breeders,” Sehgal said. “This work has also delivered pre-breeding lines to trait pipelines within national breeding programs.”

Currently, many of these lines are being used in trait pipelines at CIMMYT to introduce these novel genomic regions into advanced elite lines. Researchers are collaborating with physiologists in CIMMYT’s global wheat program to dissect any underlying physiological mechanisms associated with the research team’s findings.

“Our investigation is a major leap forward in bringing genebank variation to the national breeding programs,” Singh explained. “Most significantly, this study sheds light on the importance of international collaborations to bring out successful products and new methods and knowledge to identify useful contributions of exotic in elite lines.”

Less water for better crops

Written by Bea Ciordia on . Posted in Features.

In India, nearly one-sixth of groundwater reserves has been overexploited and almost one-fifth of them is either in critical or semi-critical condition. For a country that relies heavily on groundwater for drinking and irrigation, these statistics are close to a death sentence.

India’s water crisis, however, is not unique in the region. Population growth, coupled with increasing urbanization and industrialization, has made South Asia, one of the most heavily irrigated areas on earth, highly vulnerable to water stress. Moreover, as the effects of climate change are increasingly felt in those countries, agricultural production, even at the current level, may not be sustainable.

Against this background, ensuring that water resources are used efficiently and sustainably is key to meet the world’s growing demand. Over the last decades, traditional systems of irrigation have given way to more efficient drip irrigation systems that deliver the right amount of water and nutrients to the plant’s root zone. But as farm labor shortages become more severe, investing in automated irrigation systems — which promise increased production rates and product quality — will be the only way to ensure the sustainability of agricultural production systems worldwide.

A new article co-authored by a team of researchers from the International Maize and Wheat Improvement Center (CIMMYT) and the Thapar Institute of Engineering and Technology synthesizes the available information related to the automation of drip irrigation systems and explores recent advances in the science of wireless sensor networks (WSN), the internet of things (IoT) and other communication technologies that increase production capacity while reducing costs.

“Bundling both elements — drip irrigation and automation — in water application can lead to large savings in irrigation and boost water efficiency, especially in high water-consuming, cereal-based systems like the Indo-Gangetic Plains,” explained M.L. Jat, a principal scientist at CIMMYT and one of the authors of the review.

Investing in data and youth

Smart irrigation technologies, including sensors and the IoT, allow farmers to take informed decisions to improve the quality and quantity of their crops, providing them with site-specific data on factors like soil moisture, nutrient status, weed pressure or soil acidity.

However, this information is still limited to certain soil types and crops. “To upgrade drip irrigation systems elsewhere, especially in ‘water-stressed’ regions, we need additional agricultural background data in those areas,” Jat pointed out. “That’s the only way we can effectively customize innovations to each scenario, as one size does not fit all.”

Making this data available to and readable by farmers is also essential. Here, young people can become very good allies, as they tend to be more technologically savvy and used to working with large volumes of information. “Not only are they more skilled to integrate agricultural data into decision-making, but they can also help older farmers adopt and trust intelligent irrigation systems,” Jat concluded.

Incentives against subsidies

With increasing water shortages worldwide, making the most out of every drop becomes an urgent priority. But in countries where irrigation systems are highly subsidized, farmers may struggle to see this urgency. India, for instance, subsidizes the cost of energy to pump water for farming, thus encouraging smallholders to extract more than they need.

How do we incentivize farmers in these countries to embrace water-efficient technologies?

According to Jat, using the “scientific card” can work with smallholders who, after having farmed for decades, may not change their minds automatically. “These people may be reluctant to accept incentives for water-efficient mechanisms at first, but they will surely be interested in more scientific approaches,” Jat explained, stressing that “the emphasis must be on the science, not on the technology.”

Designing profitable business models can also incentivize producers to embrace more efficient mechanisms. Farmers who have enjoyed irrigation subsidies for decades may not see any profit in trying out new technologies — but what if they are given the chance to become champions or ambassadors of these agricultural innovations? “That brings in a whole new perspective,” Jat said.

Apart from incentivizing farmers, good business models can also draw the attention of large companies, which would bring investment to boost research and innovation in drip irrigation. “More and more businesses are getting interested in smart agriculture and low emission farming, and their inputs can help conceptualize the future of this field,” he observed.
