    What farm size sustains a living? Exploring future options to attain a living income from smallholder farming in the east African highlands
    (Journal Article, 2022) Marinus, Wytze; Thuijsman, Eva S.; Wijk, Mark T. van; Descheemaeker, Katrien K.; Ven, Gerrie W. van de; Vanlauwe, Bernard; Giller, Kenneth E.
    Smallholder farming in sub-Saharan Africa keeps many rural households trapped in a cycle of poor productivity and low incomes. Two options to reach a decent income include intensification of production and expansion of farm areas per household. In this study, we explore what is a “viable farm size,” i.e., the farm area that is required to attain a “living income,” which sustains a nutritious diet, housing, education and health care. We used survey data from three contrasting sites in the East African highlands—Nyando (Kenya), Rakai (Uganda), and Lushoto (Tanzania) to explore viable farmsizes in six scenarios. Starting fromthe baseline cropping system, we built scenarios by incrementally including intensified and re-configured cropping systems, income from livestock and off-farm sources. In the most conservative scenario (baseline cropping patterns and yields, minus basic input costs), viable farm areas were 3.6, 2.4, and 2.1 ha, for Nyando, Rakai, and Lushoto, respectively—whereas current median farm areas were just 0.8, 1.8, and 0.8 ha. Given the skewed distribution of current farm areas, only few of the households in the study sites (0, 27, and 4% for Nyando, Rakai, and Lushoto, respectively) were able to attain a living income. Raising baseline yields to 50% of the water-limited yields strongly reduced the land area needed to achieve a viable farm size, and thereby enabled 92% of the households in Rakai and 70% of the households in Lushoto to attain a living income on their existing farm areas. By contrast, intensification of crop production alone was insufficient in Nyando, although including income from livestock enabled the majority of households (73%) to attain a living income with current farm areas. These scenarios show that increasing farm area and/or intensifying production is required for smallholder farmers to attain a living income from farming. Obviously such changes would require considerable capital and labor investment, as well as land reform and alternative off-farm employment options for those who exit farming.

    Advances in the registration of farmers’ varieties: Four cases from the global South
    (Journal Article, 2021-11-11) Jonge, Bram de; López Noriega, Isabel; Otieno, Gloria Atieno; Cadima, Ximena; Terrazas, Franz; Hpommalath, Siviengkhek; Oudehoven, Frederik van; Shrestha, Santosh; Pudasaini, Niranjan; Shrestha, Deepa Singh; Gauchan, Devendra; Kasasa, Patrick; Bwerazuva, Tsungai; Mujaju, Claid; Manjengwa, Sipiwe
    Over the last few decades, there has been a growing appreciation of crop varieties developed by local farmers, commonly referred to as farmers’ varieties. These varieties often have attractive characteristics for both producers and consumers, such as adaptability to harsh environmental conditions and high nutritional values. Yet they are usually not sold in formal markets, and tend to be limited to farmers’ seed systems. This is partially due to national seed laws that, in an effort to guarantee good quality seed of uniform and stable varieties, create obstacles for farmers’ varieties to reach the market. This article describes the experiences of four countries—Bolivia, Laos, Nepal and Zimbabwe—that are developing alternative variety registration systems for farmers’ varieties. Most of these cases have never been documented before. The cases present the main drivers behind and approaches to the registration of farmers’ varieties in different legal contexts and at different stages of development. We conclude that farmers’ variety registration systems can generate benefits including faster and cheaper variety releases, improved farmer incomes, and a larger diversity of well-adapted varieties in the market—but some important issues are still to be resolved.

    A Framework for Bundling Climate-Smart Agriculture (CSA) and Climate Information Services (CIS) in Ethiopia
    (Report, 2021-11-01) Tesfaye, Kindie; Tamene, Lulseged D.; Demissie, Teferi Dejene; Seid, Jemal; Haile, Aynalem; Mekonnen, Kindu; Solomon, Dawit
    Ethiopia is increasingly impacted by climate change and variability because of its greater reliance on climate-sensitive economic sectors such as agriculture. The impacts of climate change and variability are greater on a poor section of the rural community in particular because of their weak adaptive capacities. In recent years, there has been an increasing focus on promoting climate-smart agriculture (CSA) and climate information services (CIS) to improve climate risk management and adaptation of smallholders to climate change in Ethiopia. However, CSA and CIS are rarely provided to farmers in an integrated manner. Therefore, considering the current agricultural technology development and dissemination landscape and the growing digital climate agro-advisory services in the country, a CSA and CIS budling framework is developed for Ethiopia. Bundling of CSA and CIS is expected to empower farmers to make appropriate decisions on a seasonal and intra-seasonal basis, minimize 'technology failure' due to climate variability and enhance adoption of new or existing CSA technologies/practices, reduce yield loss due to climate variability, and farm costs, and increase household income and food security and enhances resilience. Moreover, the bundling framework creates an opportunity for a platform to integrate tools, technologies, and services provided by different institutions and actors. The framework is validated through stakeholder feedback, and it is expected to guide the scaling of bundled services to smallholders.

    Bragging, shirking, and hiding: Spousal disagreement among Ugandan maize farmers
    (Working Paper, 2021-05-04) Van Campenhout, Bjorn; Lecoutere, Els; Spielman, David J.
    To gain a better understanding of intrahousehold bargaining processes, surveys increasingly collect data from co-heads individually. Answers provided by spouses on the same set of questions often differ substantially, alternately attributed to measurement error, poor framing within the cultural context that leads to systematic biases, or other common challenges associated with surveys. However, recent studies suggest that differences in responses from co-heads may also be caused by spouses strategically hiding information from each other. Using detailed data on a large sample of monogamous smallholder maize-farming households in eastern Uganda, we document response patterns from household co-heads related to decision-making, labor time, and sales of farm output. We ask each spouse questions about themselves, but also about their spouse, and compare responses. We also implement two interventions to test if such spousal disagreement in reporting can be reduced by increasing cooperation between spouses and reducing information asymmetries.

    Managing Dalbulus maidis (Hemiptera: Cicadellidae) (De Long & Wolcott 1923) in the Valle del Cauca Department, Colombia
    (Poster, 2021-06) Chalarca, Jairo Rodríguez; Parody, José Aníbal; Vargas, Carlos Alberto
    “Corn stunt disease” is one of the most common and limiting diseases in Central and South America. The complex of pathogens that cause the disease in maize are: (1) corn stunt spiroplasma "Spiroplasma kunkelii" (CSS), (2) maize bushy stunt (MBS) and (3) maize fine streak virus (MFS) (Albertazzi Castro 1992, Rodríguez 2020), with leafhoppers Dalbulus maidis and Dalbulus elimatus Ball. being the vector agent. (Sierra-Macías et al. 2007). In Colombia, D. maidis was reported as a limiting pest in maize in 2016 with losses of more than 70% in the Huila region. In 2018, it was reported in Tolima and in 2019 in Valle del Cauca. Chemical control is the only tool used to manage it. In Valle del Cauca, 10 applications were reported during the crop cycle.

    One CGIAR and the Integrated Agri-food Systems Initiative: From short-termism to transformation of the world’s food systems
    (Journal Article, 2021-06-04) Govaerts, Bram; Negra, Christine; Camacho Villa, Tania Carolina; Chavez Suarez, Xiomara; Espinosa, Anabell Diaz; Fonteyne, Simon; Gardeazábal Monsalve, Andrea; González, Gabriela; Gopal Singh, Ravi; Kommerell, Víctor; Kropff, Wietske; López Saavedra, Víctor; Mena Lopez, Georgina; Odjo, Sylvanus; Palacios Rojas, Natalia; Ramírez Villegas, Julián Armando; Vega, Daniela; Loon, Jelle J. van; Verhulst, Nele; Woltering, Lennart; Jahn, Molly M.; Kropff, Martin
    Agri-food systems are besieged by malnutrition, yield gaps, and climate vulnerability, but integrated, research-based responses in public policy, agricultural, value chains, and finance are constrained by short-termism and zero sum thinking. As they respond to current and emerging agri-food system challenges, decision makers need new tools that steer toward multi-sector, evidence-based collaboration. To support national agri-food system policy processes, the Integrated Agri-food System Initiative (IASI) methodology was devel oped and validated through case studies in Mexico and Colombia. This holistic, multi-sector methodology builds on diverse existing data resources and leverages situation analysis, modeled predictions, and scenarios to synchronize public and private action at the national level toward sustainable, equitable, and inclusive agri-food systems. Culminating in collec tively agreed strategies and multi-partner tactical plans, the IASI methodology enabled a multi-level systems approach by mobilizing design thinking to foster mindset shifts and stakeholder consensus on sustainable and scalable innovations that respond to real-time dynamics in complex agri-food systems. To build capacity for these types of integrated, con text-specific approaches, greater investment is needed in supportive international institu tions that function as trusted in-region ‘innovation brokers.’ This paper calls for a structured global network to advance adaptation and evolution of essential tools like the IASI methodol ogy in support of the One CGIAR mandate and in service of positive agri-food systems transformation.
