Mother-baby trials promote conservation agriculture in Manica, Mozambique

Written by on . Posted in Features.

A testament to increased climate variability and risk for farming systems already operating on the razor’s edge, the 2014-15 cropping season will be recognized as a sad write-off by most farmers in Central Mozambique. The rains started six weeks late and most of the rainfall fell in only two months (normally it’s distributed over four), followed by a long drought and some few showers at the end.

But with funds from the CGIAR Research Program on Maize, partners from the Instituto de Investigação Agrária de Moçambique (IIAM) and CIMMYT are working with farmers in Manica Province, Mozambique, to test and promote conservation agriculture practices that better capture and retain precious precipitation, among other advantages.

As part of this, they have revived “mother-baby” trials, a participatory methodology pioneered over a decade ago by CIMMYT for testing drought tolerant maize in Africa and which was subsequently adapted for diverse agronomic practices and is used by researchers worldwide.

Comprising field experiments grown in farming communities, mother-baby trials feature a centrally-located mother trial that is set up with researchers’ support. Baby trials, which contain subsets of the mother-trial treatments, are grown, managed and evaluated by interested farmers.

Moving from “business as usual” to innovation

In Machipanda, a small village in Manica on the border with Zimbabwe, IIAM maize breeder Dr. David Mariote established three mother trials, each with two conservation agriculture-based systems and a conventional control plot, combined with four maize varieties from the Drought Tolerant Maize for Africa (DTMA) project, which is funded by the Bill & Melinda Gates Foundation, and a traditional variety, in full rotation with cowpeas.

Farmers then put up the baby trials from a menu of practices that included direct seeding with no tillage, crop rotations, residue retention, herbicide applications, fertilizer use and improved varieties. Interest was high: 54 farmers grew baby trials and some even extended their plots beyond the designated areas, in the excitement of trying something new, according to Mariote.

“Conditions are changing fast; business as usual is no longer an option,” Mariote said. “We have to offer improved technologies that farmers can use to mitigate negative effects from climate change and improve their lives.”

Mariote witnessed first-hand the synergistic benefits of combining conservation agriculture and drought tolerant maize, as part of work in the Platform on Agriculture Research and Technology Innovation (PARTI), a project funded through the US Agency for International Development (USAID) via Feed the Future and implemented by CIMMYT in Central and northern Mozambique.

With training from CIMMYT’s global maize program and technical backstopping from the CIMMYT global conservation agriculture program, Mariote sought new and stronger ways to spread these technologies. That’s when he hit upon mother-baby trials, which had never been used before with drought tolerant maize and conservation agriculture in tandem.

Farmers who grew baby trials unanimously agreed that new ways of farming are needed and that the trials had been eye-openers. In a community meeting, some said: “We often do not have money to buy expensive fertilizers but we have seen that with good agronomic practices and good maize varieties we can already increase our maize yields.”

More farmers in Machipanda have signed up for future baby trials and, as a clear indication of commitment and excitement about conservation agriculture and improved maize, they will use their own inputs to grow them.

SIMLESA’s seamlessly integrated solution for a perennial problem

Written by on . Posted in News.

Southern Africa smallholder farmers can attain food security and more income through sustainable intensification of maize-based farming systems. This was revealed during recent field learning tours in Malawi and Mozambique last month. On show were farmer-tested improved maize–legume technologies being disseminated by CIMMYT’s Sustainable Intensification of Maize-Legume Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) project.

Smallholder farmers interacted with non-governmental organizations and private-sector partners who have shown a great interest in the SIMLESA outscaling approach using lead farmers and learning sites. Some of the sites promote smallholder agriculture development by linking farmers with buyers and agrodealers, and by providing access to credit and technical training.

Conservation agriculture (CA) exhibited mixed fortunes and presented more opportunities for learning and information sharing. Due to the excessive rains experienced in January, maize on the conventional ridge and furrow farming systems was generally greener and taller than on the CA plots, although the positive rotation effects in CA were clearly evident from the healthy maize crop following soybeans. Also, some maize varieties under CA were more susceptible to diseases such as leaf rust and suffered more from pests such as white grubs which attacked maize roots.

Main points from the learning tours included:

  • Linking the smallholder farmer to input and output markets is an integral part of SIMLESA Phase II’s smallholder commercialization thrust.
  • The participation of private-sector companies in SIMLESA demonstrations is a vital exit strategy to ensure sustainability and continued engagement with smallholders.
  • CA technologies performed rather poorly in periods of excessive rainfall, and particularly so for nitrogen-starved crops.
  • Using different maize varieties could help SIMLESA recommend the best CA-ready maize cultivars capable of tolerating diseases and pests in CA systems.

Malawi Principal Secretary praises CIMMYT contributions to climate change adaptation

Written by on . Posted in News.

Malawi’s Principal Secretary for Agriculture, Erica Maganga, led a delegation of Government Principal Secretaries and seed company representatives to Mpilisi and Ulongue in Balaka District on 11 March to observe progress in conservation agriculture (CA) adoption, as part of the country’s Agriculture Sector Wide Approach Program (ASWAP).

“CIMMYT is on the forefront in promoting different options to farmers… previous challenges will now not be an issue here as farmers have been exposed to different solutions,” said Maganga, after seeing the benefits of a trial in Ulongue where maize is grown under CA using different types of residues. Over the last several years the country has actively pursued CA, implementing practices that include eliminating traditional ridge-and-furrow tillage systems, keeping crop residues and rotating maize with leguminous crops.

Malawi is smaller than the state of Pennsylvania, yet supports 17.4 million people, half of whom live below the poverty line. Global climate change has disrupted the country’s traditional rain cycles, resulting in longer droughts or extreme floods. Maize is Malawi’s primary food crop, but unpredictable weather causes longer “hungry seasons” – the months until the next maize harvest, after the previous year’s grain has been eaten. With 85% of Malawian farmers depending upon rain-fed agriculture, erratic weather jeopardizes food security and livelihoods.

The Malawian government and farmers are working vigorously to address climate variability and support projects in affected communities. One example is Tiyanjane Nutrition Group, a beneficiary of CIMMYT’s ReSEED Maize Project funded by USAID. The group is involved in small-scale farming, value addition and sale of baked goods. Farmers use the proceeds to help orphans and other people in need and to buy inputs for better farming.

“CIMMYT through ReSEED is demonstrating drought-tolerant maize varieties to farmers,” Maganga said. “I want to urge seed companies to be proactive in providing these new maize varieties to farmers.”

The delegation also visited farmers who adopted CA practices such as intercropping pigeonpea with maize. Other demonstrations showcased crop diversification, promotion of indigenous crops, nutrient management, good agriculture practices and construction of infiltration pits and lowland tracts to manage water runoff and filter pollutants.

Seed companies including Monsanto, Pannar Seed, Chemicals and Marketing Company, Total LandCare Malawi and Self Help Africa also participated.

Research highlights solutions for groundwater management in Bangladesh

Written by on . Posted in News.

Groundwater-report

A recent research report ‘Groundwater Management in Bangladesh: An Analysis of Problems and Opportunities’, published by the USAID Feed the Future Funded Cereal Systems Initiative for South Asia – Mechanization and Irrigation (CSISA-MI) project, highlights that the policy focus in Bangladesh so far has been largely on ‘resource development’ and not sufficiently on ‘resource management.’ This has resulted in drawdown of aquifers in intensively irrigated areas and high expenditure on subsidies to support the energy costs of pumping water for dry season irrigation. Unless water use efficiency practices and policies are adapted and adopted, these challenges in groundwater irrigation can become a serious threat to sustain agricultural growth in Bangladesh.

“Dry season rice production using irrigation helped Bangladesh to increase its total rice production from 18 million tons in 1991 to 33.8 million tons in 2013. However, this dramatic increase in rice production comes with costs – namely the high energy requirements needed to extract groundwater by pumps, which is a concern giving mounting fuel and electricity prices in South Asia” said Timothy Krupnik, CIMMYT Agronomist and co-author in this study.

Diesel pumps consume about 4.6 billion litres of diesel every year to pump groundwater for dry season rice production, costing USD 4.0 billion. This cost is in addition to USD 1.4 billion of yearly energy subsidies supplied by the Government of Bangladesh (GoB) to maintain groundwater irrigation. Such considerable investments add to the energy cost burden, and may not be financially sustainable in the long-term, the report says. This conclusion is underscored by the GoB’s interest to reduce energy subsidies and shift from ground to surface water irrigation, which is energy-wise less expensive.

The report highlights several supply- and demand-side solutions for sustainable groundwater management. Improving water use efficiencies through the adoption of resource conserving crop management practices such as direct-seeded rice and bed planting could help in reducing groundwater demand for agriculture. In surface water irrigated areas, use of more fuel efficient axial flow pumps that the CSISA-MI project is working with the private sector to scale out, is also crucial.

Water demand for irrigation can also be reduced by rationalizing cropping patterns – specifically by shifting from rice to more profitable crops like maize, and to other food security cereals like rice, in areas where groundwater is a concern. Involvement of water users, investments in improved water and agricultural technologies, and providing extra support for farmers making transition to less water demanding crops is needed.

Since the concept of ‘more water-more yield’ is still prevalent among farmers, the report also highlights the need for policy to focus more on awareness raising through educational programs aimed at wise water use and volumetric water pricing. In addition to technical solutions, strong linkages and improved communications between different organizations involved in the management of groundwater resources will also be required to shift to a more water productive, and less costly, agricultural production system in Bangladesh.

On March 18, CIMMYT Southern Africa Regional Office (SARO) celebrated 30 years of agricultural research and development.

The colourful ceremony, held amid pomp and fanfare, was attended by more than 300 people representing donors, non-governmental organizations, research institutions, Zimbabwe government departments, seed companies and farmer associations. The celebration included an on-station tour, with CIMMYT–SARO showcasing its work.

CIMMYT–SARO has been operating in Zimbabwe since March 1985 with the support of the government of Zimbabwe, and other public and private-sector partners, including the University of Zimbabwe and the Department of Research and Specialist Services. In Zimbabwe, CIMMYT conducts experiments at its main station, as well as at Muzarabani and Chiredzi sub- stations. There are also on-farm trials across the country.

Officially commemorating CIMMYT–SARO’s 30-year anniversary (SARO@30), Zimbabwe’s Minister of Agriculture, Mechanisation and Irrigation Development, Dr. Joseph Made, said, ‘’The regional office has been focusing on developing new maize varieties adapted to smallholder farmers in Zimbabwe and the mid-altitude agroecologies in sub-Saharan Africa. Since then, the office has expanded to include development of research technologies for conservation-agriculture systems, sustainable intensification of production of smallholder farms and postharvest research activities.”

Stay on course, but also look beyond yield
In a speech read on his behalf by Mr. Ringson Chitsiko, the Ministry’s Permanent Secretary, Made applauded CIMMYT’s research work on developing a stock of maize since this was a major staple in the country, and beyond. Although CIMMYT and its partners had introduced various technologies for increasing yields, the Center had to develop more technologies to mitigate the effects of climate change and other challenges.

The minister advised: “CIMMYT needs to work harder and be alert, especially in the face of the ever-growing population, climate change and variability, and new threats through maize diseases and pests. I urge CIMMYT to continue pursuing its mandate for the benefit of the Southern African region.”

In support of this goal and in recognition of CIMMYT’s sustained presence and commitment to the SADC region and Zimbabwe, the Zimbabwe government in 2012 renewed the Host Country Agreement, according CIMMYT–SARO diplomatic status. ‘’We are jointly working towards signing a new collaborative agreement to strengthen maize research to combat a new threat in the form of maize lethal necrosis [MLN] disease recently discovered in East Africa and which has a potential to wipe out an entire maize crop if it spreads to Southern Africa,’’ Made said.

MLN caused 100 percent crop loss for some Kenyan farmers between 2011 and 2012, and cases were also reported in Uganda and Tanzania.

Speaking at the same occasion, Dr. Olaf Erenstein, Director of CIMMYT’s Socioeconomics Program who represented Dr. Thomas Lumpkin, CIMMYT Director General, said CIMMYT, since its establishment in Mexico in 1966 currently has 13 representative offices around the world. Its mandate and mission is to sustainably increase the productivity of maize and wheat systems to ensure global food security and reduce poverty. The regional office, he said, is serving its purpose in contributing to increasing food security.

Just one year shy: John Chifamba (foreground, in blue shirt, and cap, facing the camera), receives his long-service certificate. With 29 years of service under his belt, he’s been with CIMMYT–SARO for almost as long as it has existed.

‘Easy Friday’: Reflect, Celebrate, Play, Plan for The Future
As part of the continued celebrations, March 27 was ‘Easy Friday: CIMMYT–SARO hosted a luncheon and sports day for its staff. Thirteen long-serving employees who served for between 15 and 29 years were honored for their commitment. The employees were from administration, finance, Global Maize Program and Conservation Agriculture Program.

Sixty-two year-old Mr. John Chifamba, a recorder who has worked for CIMMYT for 29 years, said, “CIMMYT is my home. I have gained considerable on-the-job experience in maize research. “Any plans of leaving CIMMYT?” To this, Chifamba said an emphatic no. “Very soon, it will be retirement time and I will find a plot to utilize the good agricultural practices I have seen and learned at CIMMYT.“

Joining hands: From Zambia to Afghanistan
Mekuria continued: ‘’Our partnership approach will give us more capacity to meet with our constituents at the highest level, strengthening our relationships with governments as they formulate the most effective agricultural policies for the good of their people and natural resources.”

CIMMYT says ‘Thank You!’ CIMMYT–SARO staff who have served the Center for between 15 and 29 years each received a long-service certificate, which they display here.

CIMMYT–SARO is part of the world’s largest public drought and low nitrogen stress research network. Every year 500,000 envelopes of maize seeds are sent to over 70 institutions worldwide. The demand for CIMMYT–SARO maize germplasm extends from Zambia to Afghanistan.

During the past 10 years, sustainable intensification strategies based on the principles of conservation agriculture (CA) have been successfully promoted in Malawi, Mozambique, Zambia and Zimbabwe. Making use of the combined benefits of minimum soil disturbance, crop residue retention and crop rotation, CA increases yields when compared to conventional agricultural practices after two to five cropping seasons. Trials on farmers’ fields in Malawi, for example, increased yields by 20 to 60 percent. In Zambia and Zimbabwe, yields were increased by almost 60 percent using animal traction CA technologies.

Major highlights during the 30 years existence of CIMMYT in Zimbabwe include the development and release of more than 50 maize hybrids and open pollinated varieties (OPVs) adapted to drought-prone regions. These new varieties are expected to benefit almost 12 million people, helping to enhance food security, increase livelihoods and reduce poverty in Southern Africa.

CIMMYT’s seed system activities and support in training and technical assistance have led to the emergence of smaller domestic seed companies in the various Southern African countries. Farmers’ access to seed has improved. In addition, the Center has trained more than 200 technicians and graduate students through short- and long-term training in their various disciplines. Nearly 30 percent of these trainees are women. Trainees are drawn from southern Africa, the rest of Africa, and beyond.

SIMLESA’s seamlessly integrated solution to a perennial problem, but…

And what solution is this? That Southern Africa smallholder farmers can attain food security and more income through sustainable intensification of maize-based farming systems. This was revealed during recent field learning tours in Malawi and Mozambique.

The annual field tours, which ran from February 9–19, 2015, were organized by CIMMYT’s Sustainable Intensification of Maize-Legume Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) project. A total of 224 people (147 men and 77 women) visited 11 sites. The objectives of the field tours were twofold: to examine how the new experiments under SIMLESA Phase II were progressing, and to gather farmers’ feedback on some of the sustainable intensification research interventions.

SIMLESA’s farmer-tested improved maize–legume technologies were showcased during the learning tours. Smallholder farmers interacted with non-governmental organizations (NGOs) and private-sector partners who have shown a great interest in the SIMLESA outscaling approach using lead farmers and learning sites. Some of the sites promote smallholder agriculture development by linking farmers with buyers and agrodealers, and by providing access to credit and technical training.

SIMLESA tours key pointsIn Malawi, the field visits began at Kasungu District, with 16 farmers and technical staff from Mozambique who were on an exchange visit also participating. The group visited outscaling initiatives by the National Association of Smallholder Farmers of Malawi (NASFAM), in which maize–groundnut rotations and maize–pigeonpea systems are being implemented through lead farmers. More than 120 households per field learning site are participating in the demonstrations on each of the five NASFAM sites visited.

In the mid-altitude agro-ecological region of Malawi, new maize varieties have been introduced under SIMLESA Phase II as well as new groundnut and cowpea varieties, in addition to the previously tested soybean varieties in the core on-farm exploratory trials.

Conservation agriculture (CA) exhibited mixed fortunes and presented more opportunities for learning and information sharing. Due to the excessive rains experienced in January, maize on the conventional ridge and furrow farming systems was generally greener and taller than on the CA plots, although the positive rotation effects in CA were clearly evident from the healthy maize crop following soybeans. Also, some maize varieties under CA were more susceptible to diseases such as leaf rust and suffered more from pests such as white grubs which attacked maize roots.

The next stop in Malawi was Mitundu, Lilongwe District, with new crop establishment trials. Here, various new hand-planting tools were being tested, such as jab planters, the Li seeder or planting hoe and the Oklahoma State University (USA) green seeder – all in comparison to the conventional dibble stick and traditional hoe.

The use of a Li seeder has a lot of advantages, including enabling farmers to work faster and therefore saving time, and it does not strain the back,” said Mr James Segula, a smallholder farmer. The Li seeder simultaneously opens a hole in the ground, drops seed and fertilizer, and covers the hole.

Key lessons for the Mozambique and Malawi groups were timely weeding, right maize–legume crop varieties, correct use of fertilizers, residue application and appropriate and safe use of agrochemicals.

Crossing borders to Mozambique’s Angonia District, the group visited exploratory trials which included farmer-preferred maize varieties and the new maize–soybean intercrop system being tested for the first time. In SIMLESA Phase 1, common beans intercrop failed, hence the switch to soybeans. In the central region, members of the national innovation platform which brings on board NGOs such as Total Land Care, Manica Small-Scale Farmers and the Agência de Desenvolvimento Económico de Manica (ADEM) showcased the importance of partnerships. Innovation platforms are fora for information and knowledge sharing on agricultural development. Interesting differences in the tested maize hybrid and open pollinated varieties (OPV) included better leaf diseases tolerance from the hybrid Pristine, in contrast to early maturity characteristics from the OPV.

SIMLESA’s innovation platform is working with partners such as ADEM to facilitate farmers’ access to inputs, link them to financial institutions to access credit and connect them to markets for their produce. Mr Domingos Dias, SIMLESA–Mozambique National Coordinator, said: “We commend this approach of linking farmers to input suppliers and credit providers. Lessons learned, and experience gained over the years, indicate that training alone without market links is not profitable.”

Happy Seeder, happy farmers: tillage in a single pass

Written by on . Posted in Features.

Gulshad Nabi (Chand) is a progressive farmer from Chak Dahir, Tehsil Muridke in the Sheikhupura District of Punjab Province, Pakistan. He cultivates wheat and basmati rice, which constitute his family’s only source of livelihood. Heavy tillage and burning of rice residues are the common practices for growing wheat in the region, resulting in the loss of soil nutrients, air pollution and poor food security and livelihoods for farmers like Gulshad.

The Agricultural Innovation Program (AIP), led by CIMMYT and funded by USAID, has begun testing with Punjab farmers the Zero-Tillage Happy Seeder, which sows wheat seed with fertilizer directly into the residues of the preceding rice crop in one pass and without tillage. “This practice offers a more sustainable and productive way to manage rice residues and raise wheat yields,” said Imtiaz Hussain, CIMMYT cropping systems agronomist. “It allows earlier sowing of wheat, which increases yields, and dramatically cuts the time, labor and fuel needed to plant wheat, which normally requires as many as seven tractor passes. Because the rice residues decompose on the soil rather than being burned, there is less pollution.”

In Sheikhupura District and in partnership with Engro EXIMP AgriProducts Private Limited, CIMMYT has promoted the seeder with 13 progressive farmers, including Nabi, who also received technical training in its use and in conservation agriculture practices and benefits.

After the training, Nabi used the seeder to sow wheat on just over three hectares without burning rice residues and saving more than 260 liters of diesel. At the Pakistan Agriculture Conference and Expo in Islamabad, Nabi described his experience to Mr. Sikandar Hayat Bosan, Federal Minister of Food Security & Research. “CIMMYT helped me improve my farming practices. The crop growth is great. Planting wheat with the Zero Tillage Happy Seeder is a new experience – a very modern practice that saves my time and resources,” said Nabi.

On World Water Day, photos show role water plays in food security

Written by on . Posted in News.

Water plays a vital role in irrigation and food production, accounting for 70 percent of global freshwater withdrawals, according to U.N. Water. Additionally, statistics show that water consumption for agricultural use will increase by about 20 percent by 2050.

Global efforts to protectively boost sustainable water use are reflected in proposed global anti-poverty development goals due to replace the current U.N. Millennium Development Goals (MDGs), which expire at the end of 2015.

The inclusion of water in the Sustainable Development Goals (SDGs) to “ensure availability and sustainable management of water and sanitation for all” will mark a significant shift from the current framework, which included water as a subordinate target within the MDG 7 environment target.

World Water Day on 22 March offers an opportunity to celebrate the role this indispensable resource plays in agricultural production, food security and distribution.

At the International Maize and Wheat Improvement Center (CIMMYT) we asked members of our online community to share pictures illustrating some of the ways they use water.

Their contributions can be seen on our special coverage page.

Twitter followers are also asked to share pictures via the #WaterIs hashtag and by mentioning @CIMMYT.

Conservation agriculture viable, say Ethiopian farmers, as curtain comes down on CASFESA pilot project

Written by on . Posted in Features.

“Only those of us bold enough to try conservation agriculture technologies like zero tillage and intercropping benefited a lot, while all others were left behind.” – Hunegnaw Wubie, farmer, South Achefer District, Amhara Region, North Ethiopia

As the curtain comes down on CIMMYT’s Conservation Agriculture and Smallholder Farmers in East and Southern Africa (CASFESA) pilot project, participating farmers in project demonstration sites have said that conservation agriculture (CA) practices have proven to be a viable means of improving their productivity and livelihoods, and need to be scaled up across the nation.

A farmer speaks: ‘farmer-researcher’, clergyman Enkuhanhone Alayu, said people laughed at him for expecting to cultivate crops without plowing. Now they call him even at night seeking advice.
A farmer speaks: ‘farmer-researcher’, clergyman Enkuhanhone Alayu, said people laughed at him for expecting to cultivate crops without plowing. Now they call him even at night seeking advice.

The farmers made these remarks at a one-day workshop on February 23, 2015, convened to take stock of the CASFESA experience after three years of implementation in South Achefer and Jebitehnan Districts of Amhara Region, Northern Ethiopia. The project began in June 2012 and will end in March 2015. Funded by the European Union through the International Fund for Agricultural Development, CASFESA aimed at increasing food security and incomes of poor smallholder farmers through sustainable intensification of mixed, cereal-based systems.

The project will leave a rich legacy, including:

  • adaptation and demonstration of CA-based technologies on selected farmer plots;
  • enhancing pro-poor and gender-sensitive targeting of CA-based interventions;
  • improving the delivery of information, including on technologies and market opportunities to smallholders, as well as developing policy options and recommendations that favor these technologies; and,
  • enhancing the capacity of research, and development interventions, for project stakeholders.

Attending the project closing workshop at the Amhara Region Agricultural Research Institute, Bahir Dar, in northwestern Ethiopia, were Regional Bureau of Agriculture officials; Directors of the Ministry of Agriculture Extension Process and the Ethiopian Agricultural Transformation Agency’s Climate and Environmental Sustainability Program; agronomists; representatives of relevant governmental and non-governmental and research organizations; and, above all, farmers. Keynote presentations included The Economic and Environmental Benefits of Sustainable Intensification Practices by Dr. Menale Kassie, while Dr. Mulugetta Mekuria and Mr. Yeshitla Merene presented the experience and research results from the Sustainable Intensification of Maize–Legume Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA).

Reaping where you do not harrow
Farmers spoke passionately on how CA technologies proved profitable for them and their families “in beating the odds”. Most reported harvests of six or more tonnes per hectare of maize from the CA plots – relatively better harvests than with conventional plowing methods, plus the added benefits of reduced use of oxen and labor, and attendant advantages. They also called upon officials responsible to undertake corresponding measures to ensure that CA technologies are sustainably implemented and adopted on a wider scale.

One of these ‘farmer-researchers’, clergyman Enkuhanhone Alayu, narrated how people at first ridiculed him when, three years ago, he volunteered to demonstrate CA practices on his meagre plot of land. They laughed at him “for expecting to cultivate crops without plowing” – a reference to minimum tillage practices that the project advocates as a central element of conservation agriculture.

“But when they later saw that we were cultivating more quantity of maize per unit of land, they were surprised and people who had called me a fool began calling me even at night seeking advice on how they can replicate CA practices on their plots and gain the benefits,” Alayu said. “Zero tillage practices, which require considerably less labor, are even more relevant at this time when oxen are increasingly becoming very expensive and most farmers are not able to afford them.”

Another farmer speaks at the meeting.

Unto the next generation…
Another farmer, Ato Hunegnaw Wubie, said he was so pleased with CA technologies that he also taught his children how to do it on a portion of his land allotted to each of them. “One of my six children was so successful that this year he was able to reap 66 kilos of maize from a 10 by 10 meter plot. He sold his harvest at the market, and, with some additional money from me, bought a bicycle that he uses for transport to and from school. Only those steadfast enough and willing to learn new things will reap the benefits from such novel practices,” he added with pride.

And the farmers were not alone. Speaking at the workshop, the Deputy Head of Amhara Region Bureau of Agriculture, Dr. Demeke Atilaw, noted that maize production in the region stands at a meagre 3.2 tonnes per hectare, and that one reason for this is that “our agricultural practices didn’t include conservation agriculture. This needs to change both at the regional and national levels.” He further pledged that the bureau will work towards sustainably implementing these technologies with a view to increasing maize yields to eight tonnes per hectare.

Roadmap to national goals: “… projects alone cannot bring about significant change…”
In addition to CASFESA, CA technologies are being implemented in the region by SIMLESA, a CIMMYT project in Ethiopia, as well as in Kenya, Malawi, Mozambique and Tanzania. Presenting the experience of SIMLESA thus far, project leader, Dr. Mekuria told the participants that “the experience of both these CIMMYT projects, promising as they are, cannot alone bring about significant change unless they are scaled out using more new varieties of maize and sustained through meaningful institutional involvement – especially that of agencies at all levels of government.”

CIMMYT Agricultural Economist and CASFESA project coordinator, Dr. Moti Jaleta, also said that the experience of CASFESA has demonstrated that CA technologies are economically viable and thus worth pursuing on a wider scale and in a sustainable way. He particularly commended those farmers who volunteered to provide portions of their land as demonstration plots for CA technologies. “Their efforts and dedication have now paid off,” he noted, adding that project end does not mean that CASFESA will leave precipitously: there are still monitoring and evaluation and other wind-up tasks before project exit.

The Deputy Director General of the Amhara Regional Agricultural Research Institute, Dr. Tilaye Teklewold, summed up the mood of the day when he said that CASFESA’s experience in Amhara Region has shown that conservation agriculture is an ideal way of increasing the productivity of maize in the region, and that “concerted efforts are needed to raise the awareness and dedication of all actors involved in the region to implement these technologies and ensure lasting food security in the region and beyond.”

Researchers define and measure “sustainability”

Written by on . Posted in News.

Leading specialists on the sustainable intensification of agriculture tried to hammer out indicators for assessing “sustainability,” a development term that refers roughly to the health and longevity of a system, at a 13 February workshop in San Jose, California.

Sustainability“Sustainable intensification seeks to increase farm productivity while conserving social and ecological resources, said Rishi Basak, consultant for CIMMYT’s Global Conservation Agriculture Program (GCAP) who took part in the event, held during the American Association for the Advancement of Science (AAAS) annual meeting, 12-16 February.

Santiago López Ridaura, CIMMYT GCAP Systems Agronomist, also attending the workshop, said “We are all interested in understanding and quantifying the impact of our research for development activities on the sustainability of agriculture and rural livelihoods. This workshop brought donors and researchers from different disciplines to discuss a common framework, indicators and metrics to do so. I believe it is an important step forward towards a common goal.”

Measuring sustainability remains a challenge, as it involves complex biophysical, environmental and socioeconomic interactions. “There are no widely-accepted indicators for the various dimensions of neither sustainable intensification, nor thresholds or benchmarks for those indicators,” Basak explained. “Lacking unified metrics for comparisons across initiatives, specialists tend to focus on specific practices— for example, conservation agriculture or agroforestry — rather than overall outcomes of sustainable intensification.”

The framework developed at the AAAS workshop is intended to provide for standardized methods that can be adapted for large- and small-scale farms. It will facilitate cross-program learning and assessment based on a set of indicators that are widely monitored or can be easily integrated into existing programs, such as “factor productivity” and “resilience.” These indicators will be measured by returns to labor and land, and by the variance in gross margin, respectively.

“Thinking about key indicators brought us back to basics: what are we trying to achieve when undertaking sustainable intensification projects and how do we know if we are successful?” Basak stated. “What data should we collect, how do we tell our success stories, and how can we compare results between projects?”

Workshop participants agreed to begin testing the indicators in the field, broaden consultation on the draft indicators and hire someone to provide intellectual leadership and coordination going forward.

“Having a set of indicators to assess our progress towards desired goals is very important. These indicators should not only help us in assessing progress, but also capturing main synergies and tradeoffs involved in our interventions,” said Ridaura.

The workshop immediately preceded a special symposium entitled “Beyond Intensification: Measuring the ‘Sustainable’ in Sustainable Intensification” on 13 February. The symposium was organized by Jerry Glover, Senior Sustainable Agricultural Systems Advisor, U.S. Agency for International Development (USAID), and included the participation of Tracy K. Powell, USAID Agricultural Research Advisor based in Ethiopia; Gordon Conway, Professor of International Development, Imperial College, London; Sieglinde S. Snapp, cropping systems and soil management specialist, Michigan State University; Peter Thorne, crop-livestock systems scientist, International Livestock Research Institute; Cheryl A. Palm, Senior Research Scientist and Director of Research, Earth Institute, Columbia University; and Bruno Gerard, Director, CIMMYT Global Conservation Agriculture Program.

Maize and wheat Super Women campaign highlights diversity

IWDbuttonEL BATAN, Mexico (CIMMYT) – A social media crowd sourcing campaign initiated to celebrate the achievements of women has led to more than a dozen published blog story contributions about women in the maize and wheat sectors.

Each year, International Women’s Day gives the world a chance to inspire women and celebrate their achievements. This year, the International Maize and Wheat Improvement Center (CIMMYT) put out a call asking for blog contributions from the social media community.

CIMMYT asked readers to submit stories about women who have made a difference in the maize and wheat sectors, including women involved in conservation agriculture, genetic resources, research, technology and related socio-economics.

The “Who is Your Maize or Wheat Super Woman?” stories are featured on the CIMMYT website from Monday, March 2, 2015 in the lead up to International Women’s Day on Sunday, March 8, 2015.

Contributions include blog stories about women from Britain, Canada, Guatemala, India, Indonesia, Kenya, Mexico, and the United States. Their stories will also be made available in Spanish-language.

CIMMYT, Washington State University and Total Land Care (TLC) recently published a series of extension bulletins to spread awareness of the potential benefits of conservation agriculture (CA) techniques for farmers in Malawi.

The study, “Sustainable Intensification and Diversification on Maize-based Agroecosystems in Malawi,” took place over three years in the districts of Nkhotakota and Dowa, and was sponsored by the CGIAR Research Program on Maize through a Competitive Grants Initiative.

Over the study period, three different cropping systems — zero-tillage, conservation agriculture, and conventional tillage — were applied to smallholder farms. The three extension bulletins detail their respective impacts on crop yields and residue production, soil-water relations and the economic impacts for smallholder households.

The bulletins have been printed for distribution to Malawian extension agents and non-governmental organizations and, ultimately, to share with farmers.

 

The Findings

In the study, the zero-tilled maize plots incorporated only two of the three principles of CA – no tillage and residue retention – but not crop rotations, while conservation agriculture and conventional tillage incorporated diverse cropping systems.

It was found that crop rotations had the greatest impact on maize yields, leading to higher yields in conservation agriculture and conventional tillage than in continuous no-till maize.

Water infiltration was greatest in no-till maize and conservation agriculture, with 90 percent of applied water infiltrating into soils in the no-till plot and 60 percent under conservation agriculture, in Nkhotakota District. Sediment runoff was greatest in conventional tillage in both districts.

The study found that conservation agriculture used labor more efficiently than conventional tillage in smallholder plots, although variable costs were lowest in conventional tillage.

The authors of the bulletins are Dan TerAvest (Washington State University), John Reganold (Washington State University), and Christian Thierfelder (CIMMYT).

The bulletins are available in PDF format and can be downloaded here.
