research: Sustainable agrifood systems

Empowering women in agriculture through SIMLESA

Written by on September 23, 2015. Posted in News.

CIMMYT’s project on Sustainable Intensification of Maize-Legume-based Cropping Systems for Eastern and Southern Africa (SIMLESA) and the Agricultural Research Council (ARC) of South Africa hosted a five-day gender training workshop on 24-29 August in Pretoria, South Africa.

Called “Situating Gender in SIMLESA”, the workshop aimed at increasing awareness of gender issues in agricultural research and development, and identifying practical solutions to integrate gender into SIMLESA. It brought together a core team comprised of SIMLESA’s project leader, project manager, gender focal points, monitoring and evaluation specialist, communications specialist, and country coordinators. In his opening remarks, Litha Magingxa, ARC Group Chief Executive (Agri-Economics and Capacity Development), commended SIMLESA for the gender training.

Working closely with the ARC, CIMMYT gender specialist Vongai Kandiwa provided technical training to 14 participants on gender analysis tools, leadership skills, and competencies. Given the coordination role that SIMLESA gender focal points play within countries, it is essential that they have solid interpersonal and leadership skills, in addition to their gender expertise.

“This is a particularly exciting workshop because it demonstrates a strong commitment by CIMMYT and SIMLESA to actively invest in building skills and finding practical ways of integrating gender into ongoing activities,” said Mulugetta Mekuria, SIMLESA Project Leader. “The workshop has highlighted some of the gender-based constraints that women and men face when they try to adopt, adapt, and benefit from sustainable intensification options. This is a critical first step to improving gender awareness and equality in the rural smallholder agriculture sector where SIMLESA operates.”

Of the poor who depend on maize for their livelihoods and food security in East and Southern Africa, more than half are women and girls. Although women play a crucial role in farming and food production, they often face greater constraints in agricultural production than men. Rural women in East and Southern Africa are also less likely than men to own land or livestock, adopt new technologies, access credit and financial services, and receive education or extension advice, according to the Food and Agriculture Organization of the United Nations.

Participants discussed challenges and opportunities to embed gender within the relevant SIMLESA work sub-objectives. They collectively identified gender entry points, specified monitoring and evaluation indicators, and agreed on an effective accountability framework. They also agreed on what should be done across all SIMLESA countries in diverse areas such as socioeconomic research, strategic gender research, participatory selection of alternative sustainable intensification options, and seed systems.

As Kandiwa told the participants, “Careful integration of a gender perspective into the research process ensures that maize and legume research for development leads to positive and substantive outcomes.”

The participants were expected to return to their respective workplaces and apply the knowledge and skills they gained at the workshop. Almost immediately, country coordinators will work closely with objective coordinators and gender focal points to ensure gender relevant activities are budgeted for during SIMLESA’s annual planning meetings, effectively implemented, and accurately reported. The ARC undertook to develop a gender capacity building strategy for SIMLESA.

In SIMLESA II (2014-2018), the aim of gender integration is to consolidate the gains made during SIMLESA I (2010-2014). Through the Association for Strengthening Agricultural Research in Eastern and Southern Africa (ASARECA), SIMLESA I strengthened the capacity of more than 1000 individuals by providing gender-sensitive training at times and places that were convenient for both men and women, to ensure equal access to the skills and knowledge needed to succeed in agriculture.

Additionally, ASARECA documented in-depth case studies to improve SIMLESA’s understanding of the best practices for gender analysis and development. SIMLESA II is poised to build on this foundation and integrate gender effectively.

As part of CIMMYT’s ongoing collaboration with the Ningxia Academy of Agriculture and Forestry Sciences and the building of an innovation platform there, we have refurbished our site and undertaken a number of trials that reflect the concepts of sustainable intensification, which increases food production from existing farmland while minimizing pressure on the environment.

The site at Litong just outside the city of Wuzhong in Ningxia Province has been modified and now boasts a paved parking area, all-weather access roads and field paths, and an array of signage that explains CIMMYT’s activities and the history of conservation agriculture undertaken by CIMMYT-China in this part of the country.

CIMMYT recently tested a zero-tillage (ZT) rice transplanting operation with a 9 row transplanter from Jiangsu province. The idea came from viewing a short video taken some years ago of a conventional transplanter being used under ZT conditions in Bangladesh. In Ningxia, recently harvested wheat fields were irrigated and rice seedlings were planted into standing wheat stubble without any further modification to the planter. In contrast, rice was conventionally transplanted in an adjacent field, which required two days of field preparation including inversion plowing, leveling and puddling at an extra cost of USD $375 per hectare.

Zero-till rice transplanting not only saves time, labor and fuel, but also minimizes soil disturbance, maximizes residue retention, and mitigates moisture and nutrient loss. Results from these trials will demonstrate the effectiveness of transplanting rice into ZT winter wheat standing stubble.

Relay and intercropping

Monocropping farming systems are predominant in Ningxia, with the same crop planted year after year. The region has very cold winters and short summers, but with the use of short season varieties and relay cropping, double-cropping and crop rotations can be realized in the region. Double-cropping is a form of sequential cropping in which two crops are grown in sequence within a year on a piece of land by seeding or transplanting one before or after harvesting the other.

To that end, five maize cultivars were relay-planted into winter wheat on 17 June, around two weeks before harvest; the plot was previously intercropped with 24 peanut varieties. The advanced winter wheat lines were harvested in late June and yielded quite well for the region. We expect to harvest the maize from late September to early October 2015.

Zero-till and early maturing grain crops are key to double-cropping in the region; however, the current wheat variety – Ningdong 11 – is late in maturing. Next year, the earlier maturing Ningdong 10 will be used, with emphasis on residue retention and increased stubble height during harvest, before seeding maize directly and/or transplanting rice. However, the current Chinese-made Turbo Happy Seeders will need to be modified to cope with the rougher soil surfaces encountered under ZT to ensure better seeding depth control.

GCAP to become Sustainable Intensification Program (SIP)

Written by on September 18, 2015. Posted in News.

Conservation agriculture has been a major focus of CIMMYT research, positioning the Center as a world scientific leader in the area. Following a recent internal consultation and discussions with Program Director Bruno Gerard, CIMMYT has decided to change the name of the Global Conservation Agriculture Program (GCAP) to “Sustainable Intensification Program (SIP).” This change reflects the broader research-for-development agenda that CIMMYT and the Program have progressively embraced in maize and wheat farming systems over recent years, which includes social, economic, and environmental issues beyond the strict principles of conservation agriculture. We also feel that the name should represent the Program’s objectives, rather than the means by which it works to reach them. Finally, the new name will align perfectly with those of Flagship Projects 4 of the CGIAR Research Programs MAIZE and WHEAT, which CIMMYT leads. Change will be effective on 1 October 2015.

SIMLESA-Mozambique learns more about conservation agriculture technologies in Brazil

Written by on August 13, 2015. Posted in News.

Three agriculturalists from the Sustainable Intensification of Maize-Legume Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA)–Mozambique made a training visit to Brazil on 3-13 June 2015.

The objective of the visit was for the three researchers to acquire conservation agriculture (CA) skills, with a special focus on soil health and climate change. The training sessions were also expected to give participants the opportunity to share their knowledge and experience with their Brazilian counterparts at Brazilian Corporation of Agricultural Research (EMBRAPA) sites.

“By visiting and interacting with farmers, observing trials and having discussions with CA advisors, researchers, policy makers and agriculture industry representatives, we gained new knowledge of CA technologies,” said team leader Domingos Dias, SIMLESA-Mozambique National Coordinator.

During the 11-day visit, participants were presented with real-life CA challenges so they could solve them interactively. Having learned the required theory and facts through demonstrations, question-and-answer sessions and multimedia presentations, they are now expected to apply these technologies in their respective countries.

Smallholder farmers in Mozambique are affected by the poor farming methods they practice, such as late weeding and inefficient residue application, and the lack of farm mechanization. The participants learned to use and maintain agro-machinery, such as direct seeders and rippers, as well as when to plant forage crops such as Brachiaria, which produces much biomass and whose deep root system plays a critical role in improving soil properties.

“We learned very useful practices and will test some of them under our conditions. The training in Brazil presented alternative uses of residues and rotations based on soil properties suitable for Southern African countries,” said SIMLESA-Mozambique participant Custodio Jorge.

Both farmers and extension staff who participated in the first phase of SIMLESA (2010-2014) lacked basic skills and knowledge of CA farming systems. The second phase of the project (2014-2018) is focused on filling this gap through training.

CIMMYT farm mechanization project attracts wide coverage by Ethiopian media

Written by on August 13, 2015. Posted in News.

It is not often that conservation agriculture, the subject of numerous scholarly articles and dissertations, gets wide coverage from the mainstream media in Ethiopia.

It is thus remarkable that the media gave particular attention to a training event held last June at the ILRI-Ethiopia campus and organized by CIMMYT through the USAID-funded “Africa Research in Sustainable Intensification for the Next Generation” project (Africa RISING project, www.africa-rising.net). A focus of CIMMYT’s work in Ethiopia and other countries of East and Southern Africa is to improve smallholder farming practices by exploiting the synergies between small-scale mechanization and conservation agriculture.

Reporters representing two major daily English language newspapers in Addis Ababa attended and wrote extensively about the five-day training event that the project organized for service providers from different states in Ethiopia with the objective of promoting farm mechanization and sustainable productivity.

The Ethiopian Herald gave the most coverage through a lengthy article titled “Advancing farming systems improve food, nutrition and income security.” The article describes the advantages of increasing smallholder production through the adoption of modern agricultural practices and proven new technologies such as the two-wheel tractor, which can help increase the efficiency of seed and fertilizer use, reduce labor, time and post-harvest losses, and improve grain quality and farm income. The article also recommends that “all stakeholders should identify the challenges of promoting mechanization and deliver appropriate technologies to farmers.”

The Monitor gave the story a prominent place under the headline “Two-wheel tractors to improve agriculture in Ethiopian highlands.” The story in particular mentions the role of the project in light of a draft national strategy developed in 2014 by the Ethiopian Agricultural Transformation Agency with the aim of increasing farm power available to Ethiopian farmers by as much as 10-fold by 2025.

The article also reports the testimonies of participating service providers on the suitability and ease of using two-wheel tractor technologies, vis-à-vis traditional tools. One farmer noted, “Compared with using traditional tools like oxen power… this machine will help increase my income while also saving my time.”

At the end, the article quotes FACASI project coordinator Frédéric Baudron, who noted that the trainees are expected to share their knowledge of two-wheel tractor technologies with their local communities to achieve more impact and productivity in the future.

It is worth noting that CIMMYT employs a range of methodologies to accelerate delivery of two-wheel tractor-based technologies to smallholders in selected sites in SSA countries, including: on-station and on-farm participatory evaluation of two-wheel tractor technologies; business model development; market and policy analysis; and establishment of a permanent knowledge platform as well as a common monitoring and evaluation system that includes gender-disaggregated data.

From the eye in the sky to the cell phone in the field: technologies for all

Written by on August 13, 2015. Posted in Director General's corner.

Think of all the things you do with your cell phone on any given day. You can start your car, buy a coffee and even measure your heart rate. Cell phones are our alarm clocks and our cameras, our gyms and our banks. Cell phones are not just relevant for urban living but offer an opportunity to transform the lives of smallholders beyond compare. Even the most basic handset can empower farmers by providing them with instant information on weather, crop prices, and farming techniques.

For many farmers in the developing world, cell phones are the most accessible form of technology, but are only one of many technologies changing agriculture. Innovations such as the plow, irrigation and fertilizer have shaped the history of humankind. Today, technologies continue to play an essential role in agricultural production and impact the life of farmers everywhere.

Enter the era of hyper precision

Precision farming has been around for more than 30 years, but cheaper and more robust technologies are ushering in an era of hyper precision. With increasing climate uncertainties and price fluctuations, farmers can’t afford risk, and precision agriculture enables them to increase production and profits by linking biophysical determinants and variations in crop yield. A variety of farm equipment is being equipped with GPS and sensors that can measure water needs in the crop and nutrient levels in the soil, and dispense exactly the right amount of fertilizer and water as needed.

Precision agriculture may originate from large-scale, well-resourced farms, but its concept is highly transferable and it is scale independent. The pocket-sized active-crop canopy sensors, is already a game changing technology with the potential to bring precision agriculture within the reach of smallholders. Using such sensors to read crop health provides farmers with basic information that can be used for recommended nitrogen application. This has a dual purpose, both for smallholder farmers in areas where soils typically lack nitrogen, and those that over-fertilize while simultaneously reducing profitability and causing environmental pollution.

In Bangladesh, CIMMYT researchers are developing an irrigation scheduling app that predicts a week ahead of time whether a particular field requires irrigation. Based on satellite-derived estimates of crop water use, a soil water model and weather forecasts, the underlying algorithm for the app is also being tested in the north of Mexico.

The eyes in the sky

The human eye is a remote sensor, but on a farm there are many things that cannot be seen with the unaided eye, including surface temperatures and crop changes caused by extreme weather. At CIMMYT, remote sensing devices are allowing researchers to obtain information about a large area without physical contact that would otherwise be difficult to monitor. Indeed, last month I joined researchers at CIMMYT Headquarters in El Batan, Mexico, to learn more about the use of an Unmanned Aerial Vehicle (UAV) with built-in GPS and thermal and multispectral sensors that captures aerial photography to an image resolution of 3 cm. This device is being used to capture the canopy temperature and nitrogen status of crops.

Remote sensing alone is not going to teach a farmer how to properly sow a field, take the best care of his crops or optimize returns. Remote sensing explores spatial and temporal dimensions to provide a diagnosis but the next crucial step is to turn this into recommendations on nutrient management, irrigation and crop protection. The next question is how to bring these recommendations to small farms. In a low-tech setting, this depends on knowledge transfer to provide recommendations to farmers.

Show and tell: when technology adoption becomes farmer-driven

Written by on August 7, 2015. Posted in Features.

What does the CASFESA project have to show for two-and-a-half years in Kenya?

Many poor smallholder farmers in Africa bear the brunt of infertile soils. Research offers a partial solution: Conservation Agriculture (CA) helps farmers improve soil productivity through sustainable intensification.

show-and-tellPicture2 — Farmers evaluating maize stand on the conventional versus conservation agriculture plots during field days organized in Embu.

Participants of the project closing workshop held on March 5, 2015.
And some smallholders in Africa are already reaping CA benefits. For example, the Conservation Agriculture and Smallholder Farmers in Eastern and Southern Africa (CASFESA) Project worked with farmers and other partners in Kenya and Ethiopia since 2012. CASFESA’s aim was to buffer small-scale farmers by enhancing farm resilience through better natural resource management in maize based systems.

In Kenya, CASFESA ran for two-and-a-half years in Embu County. At a summative closing workshop held at Embu on 5 March 2015, farmers shared their CASFESA experience. For some of them, the project transformed their farming with remarkable benefits, due to their commitment, as well as the commitment of other key actors in CA dissemination such as the Kenya Agricultural and Livestock Research Organization.

In Kenya, CASFESA promoted three main technologies targeting maize farmers. The technologies are maize and legume intercropping, residue retention and zero tillage with permanent furrows and ridges. Thirty farmers in 15 randomly selected villages volunteered their farms for demonstrations showcasing the three technologies in tandem. Practical demonstrations were done during farmer field days in the selected villages to compare the performance of maize and beans using conservation agriculture and using normal practice. Intercropping is not new and is already very common in the area.

Moti Jaleta, CASFESA Project Coordinator, observed, “From a quick adoption monitoring survey, we noticed about 60 percent of the sample farmers have tried at least some of these techniques with keen interest to continue. The success of the CASFESA Project in Embu has been in getting these technologies to the farmers through practical demonstration, and linking them with farm input suppliers. With this, I believe we have accomplished our task in supporting the smallholders to improve their crop management.”

Participants of the project closing workshop held on March 5, 2015.

Indeed, a good number of farmers in the villages started using zero tillage with permanent furrows and ridges covered with maize residue. But there was a hitch: initially, adopting the full suite of sustainable-intensification practices appeared unpopular. And why was this? Not because of the practices themselves but because most farmers use maize residue for animal feed. This made residue retention for mulching and enhancing soil fertility a big challenge. So how did the farmers themselves – independent of the researchers – get around these unfavorable trade-offs? Let’s hear it from them.

One farmer, Nancy Mbeere, who adopted CA, harvested an additional eight bags of maize from her small farm. And she did not keep her new know-how to herself: “I have trained my three neighbors on this new technique and they have already started using furrows and ridges and residue retention in their maize shamba [farms].”

Nancy and her neighbors found a solution on animal fodder. “We agreed to have one in every three rows remain in the field as residue and use the other two as feed,” explained Nancy.

For Bethwel Kathiomi, another CA farmer, when his farm had two very good seasons, other farmers approached him for tips on his new-found farming technique. “People kept stopping by my farm to ask questions, and I was happy to share this information with them.”

At the closure workshop, farmers attending committed to continue sharing their experiences and successes, and to support each other through small groups to learn, and access inputs like fertilizers, herbicides and improved seeds. This community commitment should lead to greater CA adoption, given the attention CA benefits are drawing going by the experience of Bethwel and Nancy. It would therefore appear that in this particular case, CA has successfully moved from researchers to farmers, who are now the ones propagating CA practices. Good news indeed for impact, reach and sustainability!

MasAgro impacts: four years harvesting sustainability in Mexico’s farmlands

Written by on July 18, 2015. Posted in News.

Luz Paola López, Sustainable Intensification Program for Latin America

The “Impactos #4MasAgro” communications campaign that CIMMYT’s Sustainable Intensification Program for Latin America conducted from 23 September-1 December in Mexico, published the results that the MasAgro initiative has obtained during the four years it has been operating in farmers’ fields in Mexico.

One of the campaign’s objectives was to promote MasAgro as an inclusive farm production model and position Mexico as a disseminator of agricultural technology that seeks to achieve global prosperity and food security. Among the impacts publicized in the campaign were:

The National Agricultural and Livestock Survey indicated that between 2012 and 2014, conservation agriculture increased by 12%, while crop rotation increased by 7.2%; both were actively promoted by MasAgro.
According to Mexico’s Agricultural and Livestock Information Service, in 2014 the average maize yield in temperate regions was 2.39 t/ha, while in MasAgro’s areas of influence, it was 4 t/ha.
The income of maize farmers who participate in MasAgro increased 9-31%, while wheat farmers’ income increased up to 25%.
Forty-two national seed companies that work with MasAgro Maize now hold 28% of the improved maize seed market.
MasAgro’s improved seed, technologies, and sustainable cropping practices have been adopted on 440,000 ha, and MasAgro has had indirect impact on 1 million ha through training, field events, etc.
Nine Mexican students have received scholarships and trained to obtain Ph.Ds. in wheat physiology at universities in Australia, Chile, the US, and the UK.
A Maize and Wheat Molecular Atlas has been developed that contains maps showing the characteristics (soil type, climate, and adaptation) of sites where native landraces have been collected, along with demographic information (race, use, and productivity), and space, time, and genetic distances.

The campaign became known in social networks through the hashtag #4MasAgro, which had 3,468,237 hits. We also used our own publications, such as the EnlACe Bulletin, which published 11 special issues, and MasAgro Móvil, which sent out 6,214 messages on impacts to its users. In addition, 34 articles were published in Mexican newspapers and news sites, 9 interviews were broadcast over the radio and 2 on television, with an estimated audience of 2,843,345.

There’s no doubt that the campaign’s success was due to the participation of MasAgro collaborators, given that institutions, farmers, scientists, and extension agents took up the messages and spread them through social networks, at meetings and other events. In conclusion, “Impactos #4MasAgro” is a great example of a team working to communicate agricultural innovations.

Looking towards the future: Govaerts examines food security and nutrition in a changing world

Written by on July 6, 2015. Posted in News.

Bram Govaerts shares a quote from Dr. Norman Borlaug with the audience: “I personally cannot live comfortably in the midst of abject hunger and poverty and human misery, if I have the possibilities of—even in a modest way, with the help of my many scientific colleagues—of doing something about improving the lives of these many young children.” Photo: Jennifer Johnson

Bram Govaerts, associate director of the Global Conservation Agriculture Program (GCAP) and leader of the Sustainable Modernization of Traditional Agriculture (MasAgro) program, made a presentation on the future prognosis of food security and the actions that must be taken to achieve it at the Prospectiva del Mundo (World Prospective) Mexico 2015 conference on 25 June. The conference, organized by the National Autonomous University of Mexico (UNAM) and the Mexican chapter of the World Future Society, brought together national and international experts in fields such as development, education, finance and agriculture.

These experts were gathered in order to draft a “charter of human duties,” an initiative proposed by the late Nobel Laureate Jos Saramago, who believed that there was a global need for a charter that would define the responsibilities, not just the rights, that each human being has to the development of their surroundings. The charter will later be presented to the United Nations.

Govaerts co-presided over a panel on nutrition and food production alongside Fernando Soto Baquero, FAO representative in Mexico. The panelists were tasked to propose duties for the charter and to answer the question: “How can we improve food distribution in a way that does not harm consumers while maintaining a profitable industry?”

In his presentation, Govaerts highlighted the challenges facing food security in the coming years. “It is not just a question of producing more food, but of producing food that is more nutritious and affordable, with less impact on the environment,” said the recipient of the 2014 Borlaug Award for Field Research and Application. “We must end hidden hunger.”

He emphasized the necessity of using the genetic materials stored in CIMMYT’s gene banks to develop improved varieties, and to ensure that these varieties can be productively used by farmers. “CIMMYT is the home of one of the greatest jewels in the world: 130 thousand wheat accessions and 35 thousand maize accessions that represent the global biodiversity of these grains. However, if we don’t take advantage of our stored genetic material to create better varieties, our collection is nothing more than a refrigerator full of boxes.”

Govaerts proposed five duties for the charter of human obligations: investing in research for sustainable rural development; giving priority to family farming and small and medium producers; more equal opportunity for farmers, especially women; sustainable intensification; and further developing market opportunities for producers. He ended his presentation with a call to action, urging the audience to take the world’s duty to agriculture to heart.

“We have a great challenge before us, and a great decision to make: we will need to feed 9 billion people in 2050, and we can either do it unsustainably or sustainably. There is a lot of potential in this room, but we cannot feed 9 billion people on potential alone. We need everyone’s help and actions, and I invite you to join us.”

Director General Martin Kropff on Science Week 2015: “Taking CIMMYT to the next level”

Written by on June 30, 2015. Posted in News.

During Science Week (15-18 June) held at CIMMYT headquarters in El Batán, Mexico, scientists from around the world gathered to share the successes and review the activities of different CIMMYT programs. Attendees sought to find solutions to help meet global food needs related to basic cereals, as well as combat poverty and face the challenges posed by climate change.

CIMMYT staff from around the world came together to discuss key points and identify new opportunities for improving work quality, learn-change processes, work plans for the coming decades and CIMMYT’s role in science and development.

“The main objective of this Science Week is to take CIMMYT to a higher level of quality and create more impacts,” said CIMMYT Director General Martin Kropff, who welcomed scientists from all over the world. Kropff highlighted the importance of research to learn change processes for the next decades and reaffirm CIMMYT’s goals while interacting with external partners.

For Kropff, Science Week is an opportunity to develop better communication channels so that the ideas of all participants can help formulate a new strategy that fosters better cooperation among the different CIMMYT programs in order to achieve the best impacts.

Kropff also mentioned the importance of CIMMYT’s genetic breeding work, the work done in our germplasm banks and of strategies aimed at achieving sustainable intensification of cereal production worldwide.

“CIMMYT is a great institution and has grown very quickly, so it is necessary to put all our scientists to work and develop new plans, new projects and new ways of making future impacts,” said Kropff.

In his final remarks, the Director General said he was very happy to be part of CIMMYT because of the great scope for improvement that events like Science Week provide. “This is the best start one could have, to know all CIMMYT staff worldwide and that they know me, so we can communicate more openly,” Kropff said.

An international conservation agriculture (CA) workshop to be held during China Science Week (30 June–4 July 2015) will bring CIMMYT CA researchers, colleagues and national researchers together with the objective of building agro-ecological capacity among researchers in western China. At the workshop, hosted by CIMMYT-China, participants will discuss subjects such as CA successes and the science and practical agronomy underpinning CA, and will view field displays of CA benefits.

The workshop will advance international exchange and future collaboration through CIMMYT-China’s Global Conservation Agriculture Program (GCAP). China, a vital component of GCAP, plays an ever-increasing role in agricultural development across Asia and Africa. For example, GCAP-China collaborator Zhang Anping from the Nanjing Research Institute of Agricultural Mechanization recently returned from a 12-month machinery development program in Zimbabwe sponsored by the Chinese Government. Zhang will be hosting CIMMYT-GCAP on an agricultural machinery tour in Shandong Province following China Science Week.

Internationally renowned experts will be joined by CIMMYT’s GCAP team who will provide training and present CA research, development and extension practices, and share their expertise on CA issues that arise across Africa, Latin America and South Asia. Danny Decombel, Crop Nutritionist who has lived and worked in China for 27 years, will provide insights on nutrient and plant management and monitoring systems. Carl Timler of Wageningen University will provide hands-on training on the use of Farm DESIGN computer models and other farming system analytical tools. Farm DESIGN is a product of Wageningen University’s Farming Systems Ecology group.

National scientists will discuss new technologies, scientific advances and scholarly publications in China. Representatives from Gansu Agricultural University, The Grassland Institute of Lanzhou University, Gansu Academy of Agricultural Sciences and local agronomy consultants, in partnership with GCAP-China, will also be organizing the event.

In addition to the workshop, a participatory learning field day will be held at Dingxi Research Station in Gansu Province. During the field day, participants will learn about challenges to CA adoption, and will view demonstrations of conventional vs. CA treatment of water-holding capacity, infiltration, runoff, soil strength, plant nutrition levels and crop water use.

CIMMYT representatives attending will include Bruno Gerard, GCAP Director; M.L. Jat, Senior Cropping System Agronomist; Frederic Baudron, Farm Mechanization and Conservation Agriculture for Sustainable Intensification (FACASI) Project Leader; Santiago Lopez Ridaura, GCAP Systems Agronomist; and Tim Krupnik, Systems Agronomist.

Also in attendance will be professors John Bennett (University of Southern Queensland Australia), Enamel Haque (Murdoch University Perth Australia) and Jeremy Whish (CSIRO Australia). National representatives include Yang Changrong, expert in agro-ecology; Lan Yubin, leading expert in precision agriculture at South China Agricultural University; Pan Genxing, expert in soil biology and amendments at Nanjing Agricultural University; and Wang Yingkuan, Editor-in-Chief of the International Journal of Agricultural & Biological Engineering and Vice Secretary General of Chinese Society of Agricultural Engineering.

Conservation agriculture in Africa: where does it fit?

Written by on June 9, 2015. Posted in Blogs.

Conservation agriculture (CA) encompasses the principles of minimum soil disturbance, retention of crop residues on the soil and diversification through crop rotations and associations. Worldwide, CA adoption exceeds 125 million hectares. Its benefits include reduced production costs and soil degradation, more effective and efficient use of resources like water and fertilizer, and greater overall cropping system productivity. CA-based practices have recently regained scientific attention as part of newly emerging concepts such as sustainable intensification, ecological intensification and climate-smart agriculture.

CIMMYT’s increasing efforts to promote CA in Sub-Saharan Africa began at a regional hub in southern Africa in 2004, moved to eastern Africa in 2009, and subsequently expanded to other Africa locations. In Africa, conservation agriculture has benefitted from significant donor attention and the call to address multiple agricultural challenges, which include the pressure of expanding populations on land resources, declining soil fertility, low productivity, and the negative effects of climate variability.

Research has proven the biophysical and economic benefits of CA for Africa, yet CA adoption and spatial expansion by African farmers is relatively low, compared to its acceptance in similar agro-ecologies in the Americas and Australia.

The lack of widespread adoption in Africa has led some researchers to question the suitability of CA for smallholder farmers in Africa or the wisdom of spending resources to study and promote it. A divide between CA-for-Africa proponents and opponents in the research community has opened, obscuring issues and hindering unbiased examination of CA opportunities and constraints. Adding to the uncertainty, there is little research in Africa to assess where CA might make the best impact or, more generally, where conditions are simply too marginal for cropping systems of any type.

AFTER 10 YEARS OF RESEARCH, WE FEEL IT IS CRITICAL TO LOOK OBJECTIVELY AT WHERE WE ARE WITH CA IN AFRICA. Specifically: What is CIMMYT’s comparative advantage in the research and development of CA systems? Does “business-as-usual” — that is, conventional tillage systems — provide better outcomes? Is there any form of alternative agriculture being adopted more quickly or widely than CA? Do we gain anything if we lose our comparative advantage as a leading global CA research institute and only focus on “good agronomic practices”?

We believe that CA has great promise for smallholder farmers in sub-Saharan Africa but CIMMYT and other organizations may have approached its study and extension from the wrong angle. In particular, CA has often been promoted in Africa as a way to raise yields. In fact, short-term yield gains are common from better moisture capture and retention under CA, in seasons with erratic and prolonged dry spells. But yield benefits from CA are normally not immediate; they generally begin to appear after two-to-five cropping seasons. Smallholder farm households often live at the edge of food insecurity year-in and year-out and are undisposed to risk an innovation that raises system productivity only in the medium term.

In contrast, the adoption of CA outside of Africa has been driven by benefits such as energy savings, reduced erosion, more timely sowing, and enhanced water- and nutrient-use efficiency. Furthermore, CA adopters worldwide have typically been large-scale commercial farmers who seek enhanced and sustainable profits and, as a consequence, ways to cut production costs. So how can their positive experience apply to smallholders and be used for proper targeting and extension of CA systems in Africa?

IN OUR OPINION, CIMMYT AND ITS PARTNERS SHOULD FOCUS ON (1) identifying the key drivers that have facilitated adoption of CA worldwide and (2) delineating the niches in Africa where these drivers are present, meaning where CA is likely to fit. As a start, we may wish to look at settings where:

Farm energy is scarce or expensive (whether provided by motors, draft animals or human labor ).
Timely planting is crucial, soil degradation extensive, and climate-related stress common. (This niche might be bigger than we think in Africa)

WE BELIEVE THAT CHALLENGES HAVE TOO OFTEN BEEN CONFUSED WITH BARRIERS TO ADOPTION. Too much time and effort have been spent highlighting challenges arising when implementing CA, instead of actively looking for ways to overcome them through technological and institutional innovations, including improved working arrangements between multiple actors. Furthermore, we feel that far too many resources are being channelled by CIMMYT’s Global Conservation Agriculture and Socioeconomics Programs into diagnostic studies, without commensurate investments in applied research for innovations to address the challenges.

Future research with farmers and other stakeholders should explore opportunities to ensure that CA systems meet smallholder farmers’ needs. It should also aim to target CA principles and practices in areas where highest returns are expected. In conclusion, we believe that BUSINESS AS USUAL IS NOT AN OPTION and that, in many places where CIMMYT works, CA IS IN DEMAND to alleviate labor bottlenecks, improve the timeliness of operations, control erosion and improve water- and nutrient-use efficiency. Should this demand be ignored? Of course challenges exist, but research – and international research in particular – should not simply document challenges but also provide solutions.

Growing land scarcity, the Borlaug hypothesis and the rise of megafarms

Written by on June 9, 2015. Posted in Features.

Derek Byerlee, former director of the CIMMYT economics program (1987-94) and current visiting scholar at Stanford University and adjunct professor at Georgetown University, presented some of his latest research at a brown bag lunch at CIMMYT headquarters on 1 May. His presentation, “Growing Land Scarcity, the Borlaug Hypothesis and the Rise of Megafarms,” examined the economic and environmental benefits and repercussions of cropland expansion, the recent rise of agribusiness and the delicate balance between crop intensification and deforestation.

The “Borlaug Hypothesis” is the idea that increasing crop yields can help prevent cropland expansion and deforestation, thus alleviating hunger and poverty without dramatically increasing environmental impact. Developed by the legendary Nobel Prize Laureate and CIMMYT scientist Norman Borlaug, the postulate is controversial in environmental circles, and some researchers have published studies showing that higher crop yields in the tropics increase incentives to clear forests, thus making investments in crop research potentially counterproductive to sustainable growth.

Byerlee noted that the world has increased per capita cereal production by about 40 percent over the last 50 years on about half the arable land per capita that it used in 1961. Models developed by Byerlee and his associates show that, without CGIAR work since 1965 to develop improved crop varieties, the land area devoted to food crops would have increased by 18 to 27 million hectares, mostly in developing countries. Byerlee supports Borlaug’s claim that broad-based investment in crop research and development indeed contributes to saving the world’s forests, although estimates by Byerlee and his associates are an order of magnitude lower than those of Borlaug.

Investment in crop intensification may be more important than ever, as the world’s growing population demands ever-growing quantities of food and land. “Meta-analysis of demand estimates suggests that, given current yield trends, agriculture will require an additional 200 to 450 million hectares of land by 2030 — as much as the entire combined land area of India and South Africa,” Byerlee said. At the same time, Byerlee found that an estimated 450 million hectares of land could be available for crop expansion but is concentrated in just a few countries and its cultivation could have negative impacts on the environment and on people already using that land for other purposes.

Linked to the question of where crops should be cultivated is the issue of who will cultivate them, especially on the land frontier. Byerlee described the recent rise of “megafarms” run by agribusiness companies and examined their economic benefits (or lack thereof) in comparison to traditional family farms that still prevail across the world. Byerlee argued that family farms were more efficient, equitable and contribute to more growth than megafarms, which benefit from professional management and technologies that allow for larger scale but do not display significant cost advantages over traditional family farms. Byerlee ultimately recommends models that combine agribusiness and smallholder farms for best results.

First international training workshop on farming systems analysis in India

Written by on June 9, 2015. Posted in News.

The international training workshop “Approaches for integrated analysis of agricultural systems in South Asia: Field, to farm, to landscape scale,” jointly organized by CIMMYT and the Indian Council of Agricultural Research (ICAR)-Central Soil Salinity Research Institute (CSSRI), was held at Karnal, Haryana, India, during 18-23 May. The workshop targeted farming systems and agricultural development researchers in South Asia and provided an overview of the approaches and tools used to assess agricultural systems.

Compared to the rest of the world, South Asia’s natural resources are 3-5 times more stressed due to population and economic pressures. Several agricultural technologies and practices have been developed to address resource management challenges. However, researchers need to conduct specialized analyses of complex farming systems to find out which technologies are appropriate for farmers.

The training workshop allowed participants to share their experiences in the field and create better methods to ensure successful interventions. P.C. Sharma, Head of the Crop Improvement Program, CSSRI, commenced the workshop and greeted the participants, who comprised 30 young researchers from national research institutions and universities in India, Nepal and Bangladesh. Santiago López Ridaura, CIMMYT Global Conservation Agriculture Program Systems Agronomist, presented workshop objectives, which included introducing participants to integrated farming systems analysis as well as to modeling tools and technology designed for specific farming communities.

“This course is the first of its kind in the region,” emphasized M.L. Jat, CIMMYT Cropping Systems Agronomist. “It is unique, demand-driven and organized to strengthen the capacity of young researchers in the region so that they may more effectively help build livelihood security for smallholder farmers.”

D.K. Sharma, CSSRI Director, stressed the need for systems research in the region and how partnerships with centers ike CIMMYT have helped to successfully implement conservation agriculture, sustainable intensification and other practices. Sharma also described CSSRI’s farmer participatory model, which provides farmers with land for cultivation against their annual compensation, thereby improving livelihoods.

Workshop attendees participated in modeling, analysis and participatory exercises that helped them to better understand the challenges of technology adoption in the field. Participants also visited farms, where they learned farmers’ needs first-hand and observed the complexity of different farming systems.

The workshop was supported by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), the Cereal Systems Initiative for South Asia (CSISA) and the Sustainable and Resilient Farming Systems Intensification in the Eastern Gangetic Plains (SRFSI) project of the Australian Centre for International Agricultural Research’s (ACIAR). Other attendees included Mahesh Gathala, CIMMYT Cropping Systems Agronomist and SRFSI Project Leader; Jeroen Groot, Wageningen University Farming Systems Modeling Specialist; David Berre, CIMMYT Farming Systems Agronomist; Timothy Krupnik, CIMMYT Agronomist; and Alison Laing, Cropping Systems Modeler at ACIAR CSIRO Climate Adaptation Flagship.
