Webinars will not only focus on completed work, but many of them will be presentations of work in progress. The webinars take place on the 3rd Wednesday of each month, usually around 1.30 pm CET. The topic of each webinar will be announced on this page as well as on Twitter (@cgiarspia). If you are interested in presenting in one of the webinars and receiving feedback on early-stage work, please contact email@example.com with a brief description of your impact assessment study or idea.
Webinar #23: Using mixed-methods research to understand food choices in Tanzania
November 15, 11am-12pm CET
Presenter: Nishmeet Singh, University of Edinburgh
Discussant: Monica Biradavolu
At this webinar, Nishmeet Singh from the University of Edinburgh will present a project using mixed methods to study consumer behavior and food safety perceptions related to food environments within the Fruit and Vegetables for Sustainable Healthy Diets (FRESH) Initiative in Tanzania.
Webinar #22: Experimental studies on encouraging maize varietal turnover in sub-Saharan Africa
October 18, 12.30-2pm CEST
Presenters: Michael Ndegwa and Sarah Kariuki, CIMMYT
Discussant: Emilia Tjernstrom, Monash University
Farmers in SSA are observed to stick with well-known maize varieties they have grown for years even when newer, better adapted, and more promising varieties are available. In this webinar, Michael Ndegwa and Sarah Kariuki will present three randomized controlled trials that test different methods of encouraging farmers to switch to newer varieties.
The first study evaluates alternative ways of encouraging experimentation with new maize varieties through trial pack campaigns to facilitate cluster level social learning and information spillovers from trial hosts to fellow villagers.
The second study tests the role of drawing farmers’ attention to and encouraging experimentation with newer varieties during seed purchase through information and price promotions at the Point-of-Sale (POS).
The third study tests whether economic incentives (margin discounts) can motivate input suppliers to stock and push newer varieties to farmers.
Webinar #21: Remote sensing for impact evaluation of agriculture and natural resource management research
September 20, 2023, 1-2.30pm CEST
Presenter: Johanne Pelletier
The rapid development of remote sensing opens up opportunities for using satellite-based Earth observation (EO) data for analysis that previously relied on ground-based measures. In this webinar, Johanne Pelletier presents recent SPIA guidelines on best practices for using EO data for impact assessment. The guidelines bring in learning from 11 case studies that use EO data for impact assessment and reflect on common challenges and how to address them.
Webinar #20: Maternal and child nutritional health: evaluating the impacts of gender-differentiated interventions in Central Uganda
May 17, 2023, 1.30-2.30pm CEST
Presenters: Hardi Ahmed (University of Alicante), Teresa Molina (University of Alicante) Millan and Emily Ouma (ILRI)
This impact assessment team formed at the SPIA matchmaking in Nairobi 2022. At the webinar they will present progress made on their study.
Abstract: Malnutrition is pervasive in Uganda, with about 30% of children experiencing stunted growth. This has been linked to a lack of knowledge on the relevance of good nutrition as well as social norms limiting the availability of certain foods for vulnerable members. These challenges are most prevalent in the consumption of ASFs. In this study, we implement gender-differentiated interventions aimed at improving nutritional outcomes of children and mothers. First, we provide information on nutrition knowledge for women (T0). Then, we implement a similar information campaign, but for men (T1). This is relevant given that men control most of the household resources. Lastly, we implement an intervention that goes beyond the provision of knowledge and seeks to change behaviors regarding ASF consumption (T2). This project will test impacts of T1 and T2 relative to the baseline treatment through a clustered randomized controlled trial.
Webinar #19: Equitable and inclusive methods to promote plant health innovations - Experimental design for encouraging the adoption of Aflasafe among small-scale farmers in Nigeria

At the webinar, the team will share their progress on the project and some reflections on the matchmaking process.
Webinar #18: Pricing and Allocative Efficiency of A New Agricultural Technology
January 25, 2023, 1.30-3pm CET
Presenter: Mai Mahmoud, Tufts University
Discussant: Carly Trachtman, IFPRI
Mai Mahmoud presents a study on blast tolerant wheat in Bangladesh. The study examines the allocative efficiency of agricultural input subsidies. Using a two-stage experiment, Mai randomizes the price subsidy for a new seed variety in stage one. Subsidy amounts range from full to zero subsidies. In stage two, she randomizes free distribution across the self-selected sample of non-buyers from stage one. This design allows her to compare realized returns across the entire population with the returns among the sample choosing not to buy in stage one. She finds that the stage two free distribution increases adoption by an amount almost equal to the effect from stage one. Thus, higher prices screen out farmers who are willing to plant the new seed. In addition, she finds no evidence that choosing not to buy in stage one is associated with having lower returns from adoption. The results suggest that prices do not have a selective ability in the context of agricultural inputs.
Webinar #17: Designing an impact assessment of market intelligence for more equitable and impactful genetic innovation
November 9, 2022, 1.30pm CET
Presenter: Berber Kramer
Decisions on how to invest scarce resources in CGIAR-NARES genetic innovation systems have been predominantly supply-driven and therefore potentially out-of-sync with the demands of smallholders, consumers and agro-industry. The Market Intelligence initiative aims to maximize CGIAR and partners’ returns on investment in breeding, seed systems and other Initiatives based on reliable and timely market intelligence that enables stronger demand orientation and strengthens co-ownership and co-implementation by CGIAR and partners. In this talk, Berber Kramer presents the design of the impact assessment for this initiative, their experiences with SPIA matchmaking efforts, and how this matchmaking process contributed to the impact assessment design.
Webinar #16: Agricultural Development and Environmental Quality in India
September 21, 2022, 1.30pm CET
Presenter: Marina Ngoma
Marina Ngoma presents the results of a project evaluating the impact of a large-scale agricultural program on agricultural production and environmental quality. Starting in 2007, India launched the National Food Security Mission (NFSM), a nationwide program that supports demonstrations of improved seed varieties, distribution of subsidized seeds, and minor infrastructure projects, such as irrigation facilities. Using regression discontinuity methods, researchers investigate whether the government agricultural investment had impacts on staple food production and environmental quality.
Webinar #15: Academic matchmaking for impact assessment in One CGIAR initiatives – the experience of Excellence in Agronomy
June 15, 2022, 1.30pm CET
Presenters: Aminou Arouna (AfricaRice) and Theresa Ampadu-Boakye (IITA)
This webinar focused on Academic matchmaking for impact assessment in the One CGIAR. SPIA introduced an upcoming matchmaking event, where initiatives will be given the opportunity to present their impact assessment ideas to academic expertise and identify opportunities for collaboration.
The webinar then featured a presentation by Aminou Arouna and Theresa Ampadu-Boakye, shared the experience of academic matchmaking in the Excellence in Agronomy (EiA) initiative. The MELIA plan of EiA includes a Randomized Controlled Trial (RCT) to assess gender transformation approaches and incentives on the uptake of selected agronomic solutions. To conduct this activity, EiA is developing a matchmaking with University of Tufts which has demonstrated experience in conducting RCTs. In addition, a matchmaking has started with Wageningen University and Research (WUR) for a qualitative survey in EiA. The presentation aimed to share experiences from how these matchmakings have taken shape so far.
Webinar #14: Environmental and long-term impacts of Index Based Livestock Insurance
May 18, 2022, 2-3.30pm CET
Presenters: Chris Barrett, Steven Wilcox and Nathaniel Jensen
Droughts are a main cause of livestock mortality and poverty among pastoralists in the Horn of Africa. Index based livestock insurance (IBLI) was developed to protect pastoral households from the impacts of drought by making payouts based on satellite readings of the rangelands. IBLI has been available to pastoralists in Kenya and Ethiopia for more than ten years and has insured over USD 70 million in livestock value during this time. The first component of this study draws on administrative data from insurance firms and interviews with key actors to examine the supply and demand side drivers of diffusion of IBLI in the region. The second component of the study uses longitudinal household survey data to test for the persistence of impacts that were documented among IBLI’s clients early in the program.
The third portion of this talk explores IBLI's potential environmental impacts. Might IBLI encourage overstocking or changed grazing behaviors that harm the rangeland systems on which pastoralists rely, ultimately undermining the product's effectiveness in reducing livestock mortality risk? Or does IBLI reduce precautionary savings in-kind, thereby reducing overstocking and improving rangeland health? The study presented combines administrative roll-out data with remotely sensed rangeland quality measures.

Webinar #12: You reap what (you think) you sow? Misperception in varietal identification and farmers' behavioral adjustment
March 23, 2022, 1.30pm CET.
Presenter: Paola Mallia, Paris School of Economics
Adoption of improved seed varieties has the potential to lead to substantial productivity increases in agriculture. However, only 36 percent of the farmers that grow an improved maize variety report doing so in Ethiopia. Paola Mallia presents a paper that provides the first causal evidence of the impact of misperception in improved maize varieties on farmers’ production decisions, productivity and profitability.
Webinar #11: Using Rigorous Impact Evaluations to Understand How Gender Shapes the Effectiveness of CGIAR Innovations
February 16, 2022, 1.30pm CET.
