research: Sustainable agrifood systems

Santiago Lopez-Ridaura

Santiago Lopez-Ridaura focuses on the quantitative analysis of agricultural systems at the field, farm, landscape and regional level. By developing and applying a suit of quantitative systems analysis approaches, methods and tools, he builds a detailed understanding of the characteristics, dynamics and diversity of farming systems in a given region. Then, through multi-criteria assessments of different cropping and farming systems, he helps target interventions to specific types of farms within certain agro-ecologies.

Lopez-Ridaura works closely with farmers, farmer organizations, national and international non-governmental organizations, and agricultural research and development institutions to help them answer what technological and policy interventions are most appropriate for a given community. This enables organizations to comprehensively understand the main challenges and opportunities of specific technologies, and improve their adoption and adaptation to reach impact at scale.

Field trial design workshop for smallholder farmers who grow maize landraces

As part of the efforts of the Sustainable Modernization of Traditional Agriculture (MasAgro) program aimed at improving food security based on maize landraces in marginal areas of the state of Oaxaca, Mexico, a workshop on trial design was held from 19-21 February to improve the precision of data on improved maize landraces in smallholder farmers’ fields. Attending the workshop were partners from the National Forestry, Agriculture and Livestock Research Institute (INIFAP) and the Southern Regional University Center of the Autonomous University of Chapingo (UACh).

The objective was to continue to have positive impacts on the marginalized communities of Oaxaca, by adapting to the hillside conditions and poor, uneven and broken up soils that often characterize the plots of farmers who grow maize landraces. The very varied trial designs in farmers’ fields, plus the varied population structure of maize landraces make it difficult for scientists to create efficient designs.

The training workshop was led by Dr. Martha Willcox, CIMMYT Maize Landrace program, and designed by Dr. Juan BurgueƱo and Mr. Claudio Ayala, who sought to facilitate breeding research in smallholder farmers’ fields and to continue to work for the benefit of more than 400 Oaxacan farmers. The project’s multi-disciplinary base includes genetic improvement, agronomic management and biostatistics in order to generate greater value and scientifically confirm the benefits that are being achieved in the fields of the country’s poorest farmers.

It should be noted that during the four years that MasAgro has worked on participatory breeding (2014-2017), INIFAP, UACh and CIMMYT have found that in marginalized communities, maize landraces with the characteristics mentioned above not only yield more, but also generate higher returns on investments, which benefits farmers. Smallholder farmers grow maize in many ecological niches outside the areas most favorable for intensive commercial agriculture and in areas where hybrid improvement programs have not been introduced or worked due to the extreme conditions, including fog, drought and disease. Maize landraces are better adapted to those areas and have the culinary qualities needed to make every-day and festive local dishes.

In addition, not only has maize production for home consumption improved, but farmers are now linked to gastronomic markets. During project years and with its help, maize began to be exported, with 10,000 kilograms exported in 2014 and more than 900,000 kg exported in 2017.

In the last decade, the climate of Africa has been changing in dramatic ways. Many regions face unpredictable levels of rainfall, which can lead both droughts and severe flooding. Sub-Saharan Africa is the only region in the world with over 30 percent of children under five facing stunting – severe malnutrition, and is the only region where the rate of undernourished people has consistently increased.

The Sustainable Intensification of Maize-Legume Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) program, launched in 2010, works to improve maize and legume productivity and reduce yield risk for over 650,000 farm households in sub-Saharan Africa.

Maize is a vital staple cash and sustenance crop in most of Africa, and legumes provide nutrition, income and improve soil fertility. However, farmers’ yields are suffering due to declining soil fertility, drought and poor access to improved technologies.

Over the last eight years, SIMLESA has developed productive, resilient and sustainable smallholder maize-legume cropping systems. SIMLESA focuses on improving maize-legume cropping systems by encouraging the adoption of sustainable agriculture systems through conservation agriculture practices such as crop residue retention, crop rotation and intercropping practices to simultaneously maintain and boost yields, increase profits and protect the environment.

Recently, Elliud Kireger, director general of the Kenya Agricultural and Livestock Research Organization (KALRO), Mulugetta Mekuria Asfaw, SIMLESA project leader and Daniel Rodriguez, associate professor, Queensland Alliance for Agriculture and Food Innovation (QAAFI) The University of Queensland, wrote a joint opinion piece ā€œAfrica: Science Can Reverse ‘New Normal’ of Hunger and Climate Disasterā€ in All Africa on the impacts of SIMLESA, read it here.

The Sustainable Intensification of Maize-Legume Cropping Systems for Food Security in Eastern and Southern Africa (SIMLESA) program is funded by the Australian Centre for International Agricultural Research (ACIAR).

Building small scale mechanization capacity of service providers in Ethiopia

The project, titled ā€œAppropriate Mechanization for Sustainable Intensification of Smallholder Farming in Ethiopia,ā€ aims to increase soil fertility through direct row planting of major crops in Ethiopia, such as maize, wheat and teff. However, they identified in their pilot phase that the necessary infrastructure and supply chains were not in place to ensure project sustainability and that the involvement of the private sector would be necessary.

Therefore, the project in its second phase focused on these critical activities, especially increasing capacity of service providers to deliver services and manage their businesses, and mechanics who closely support service providers in their daily business. Mechanics work with the local spare parts representatives identified by AMIO Engineering Plc, a local private sector partner in manufacturing and dealer of small scale agriculture technologies and machinery, to ensure that the fast moving and critical parts are always available in stock at their local warehouses.

In October 2017, two trainings were conducted at the Ethiopian Institute of Agricultural Research (EIAR) in Melkassa.

The first training was organized for selected mechanics by AMIO and CIMMYT with funding from the Integrated Soil Fertility Management program (ISFM), part of the German Cooperation for International Development Agency (GIZ). The one-week training covered the use and function as well as maintenance, repair and spare parts of the two-wheel tractor (2WT).

The second training, intended for service providers (SPs), focused on capacity building and quality development of small-scale mechanization services. The 44 SPs in attendance were encouraged to exchange individual experiences and expertise about service provision businesses, technical challenges in the field and the extent of potential business opportunities.

These trainings specifically focused on the use, operation, maintenance and safety of the 2WT and its ancillaries, as with correct aggregation almost all farming tasks can be accomplished with a single machine. The use of a 2WT for these tasks reduces both the time required to establish a crop and the chore of the task, by increasing productivity of both labor and crops.

Economic assessments show that mechanized planting using a 2WT is an economically viable and attractive option for both farmers and SPs. This is especially true when services offered include full use of 2WT and attachments; as these services are useful 365 days a year.

After farmers see these technologies, they are often interested in purchasing the services associated with the equipment and service providers frequently asked to procure additional equipment.

In order to achieve the aim of increased soil fertility through direct row planting of major crops in Ethiopia, the project selected six micro-watersheds in January 2016 that corresponded to ISFM intervention sites to test the delivery of small mechanization through service provision. The sites are located in the regions of Amhara, Oromia and Tigray.

The project imported six equipment packages from China for mechanized crop establishment, harvesting of small grain cereals and water pumping. These machines were loaned to individual service providers in Oromia and Tigray, and to a farmers group in Amhara. In addition, EIAR locally manufactured six trailers and three threshers which have been be dispatched to service providers.

Furthermore, in this second phase, the GIZ-ISFM through CIMMYT with Ethiopia’s Ministry of Agriculture and Natural Resources (MoANR) dispatched 100 units of 2WT with plows, and an additional 15 trailers and 18 direct row planters that can be attached.

Based on encouraging results, the second phase of the project will focus on establishing viable, private sector-based input delivery mechanisms (maintenance and repair services, spare parts, and new equipment) and generating sufficient demand for self-sustained scaling-out processes.

A newĀ research noteĀ published for International Women’s Day,Ā details current gender gaps in rural mechanization in Bangladesh, and outlines plans to overcome these challenges.

Using simple technologies, such as multi-crop reaper-harvesters can reduce the time farmers spend harvesting by up to 80 percent and can reduce the costs of hiring field labor by up to 60 percent. The problem is that women may face cultural constraints to working in the field, running machinery service provision businesses, and do not have equal access to financing, which is a huge barrier, as the technologies can cost $500-2000 up front.

The authors suggest a number of gender-balanced approaches to scaling-out technologies such as use of targeted, selective and smart subsidies and access to finance to women-headed households, methods to spread investment risks, and prioritizing joint learning, with husbands and wives attending field courses together and jointly developing business plans.

The research note is a result of joint efforts between the USAID/Washington and Bill and Melinda Gates Foundation supported Cereal Systems Initiative for South Asia (CSISA), the USAID/Bangladesh CSISA – Mechanization and Irrigation Project, and the the USAID/Washington fundedĀ USAID fundedĀ Gender, Climate Change, and Nutrition Integration Initiative (GCAN) project, all of which involve collaborations between the International Maize and Wheat ImprovementĀ Center, the International Food Policy Research Institute, International Development Enterprises, the International Rice Research Institute and the CGIAR Research Program on Climate Change, AgricultureĀ and Food Security.

New guides help agricultural scientists think gender in research design

EL BATAN, Mexico (CIMMYT) – A new set of resources has been released to aid agricultural researchers integrating gender sensitivities into their research for development projects. The guidance notes are based on findings from GENNOVATE, a global comparative gender norms research initiative, funded by the Bill & Melinda Gates Foundation.

ā€œIntegrating gender into research is challenging,ā€ said the project leader Lone Badstue. ā€œThe purpose of these GENNOVATE resources is to inspire and help scientists who are not gender experts to think gender into their own work.ā€

Agricultural research often fails to use gender analysis, which provides important information on women’s and men’s different needs and opportunities in agriculture, Badstue said.

In a bid to turn the tide, GENNOVATE initiated a series of tools and guides to give evidence about gender roles in agriculture, challenge assumptions and provide gender-inclusive data collection instruments that are easily accessible to researchers.

ā€œThese resources provide evidence-based inputs and recommendations on how to integrate gender considerations in research on, for example, climate-smart-agriculture, conservation agriculture, mechanization, farmer training events and more,ā€ said Badstue. ā€œSome of the tools have broad geographical relevance, while others have a regional or even country-level focus.ā€

The resources draw on GENNOVATE research, which focuses on how gender norms influence women’s and men’s abilities to learn about, adopt and adapt innovations in agriculture and natural resource management. This research initiative runs across multiple CGIARĀ research programs to provide contextually grounded evidence on how gender interacts with access to information, resources and decision-making processes.
