Kenya Rural Household Panel Survey - Household and maize data 2010 & 2013
Kevin Oluoch Hugo De Groote Zachary Gitonga (2022)
Data from two CIMMYT and KALRO household surveys representative of six maize production areas or agroecological zones in Kenya. The surveys were conducted in 2010 and 2013 collected data on farmer demographics, adoption of improved technologies and practices, marketing, access to agricultural information, and farmer adaptation to climate change.

Nutritious Maize for Ethiopia (NuME) - baseline survey
Hugo De Groote Moti Jaleta Zachary Gitonga (2015)
Maize is now the major food crop in Ethiopia, but it has poor nutritional quality, in particular inadequate levels of the essential amino acids lysine and tryptophan, which reduces the overall biological value of its protein. In response, quality protein maize (QPM) was developed, combining improved protein quality with storage and agronomic qualities similar to those of conventional maize. Consumption of these varieties leads to greater protein utilization and greater rates of growth among malnourished young children. Adoption of QPM in Ethiopia so far has only been successful in agro-ecological niches where varieties were first released, while farmers expressed a clear demand for later-maturing varieties, similar to the popular BH660 variety. Further breeding at the Ethiopian Institute of Agricultural Research (EIAR) and CIMMYT has resulted in the release of new QPM varieties adapted to all major maize-producing agro-ecologies in Ethiopia. The Nutritional Maize for Ethiopia (NuME) project was therefore developed to bring these QPM varieties to rural households, to increase intake of quality protein and to improve nutritional status and food security. To guide the project’s implementation and monitor its progress, a baseline survey was conducted to measure baseline parameters, including adoption of QPM, awareness of its benefits, food consumption, nutritional status, and food insecurity. To inform the project on its gender strategy, intra-household resource allocation was also studied, and to inform the dissemination and information strategy, the sources of information were also analyzed.

Harvestplus household survey, Zambia 2011, section on storage and climate
Hugo De Groote Zachary Gitonga Kai Sonder (2023)
In this data base, representative georeferenced farmer survey data from Zambia from 2011 are combined with climate data to estimate storage losses, analyze their relationship with climate, and estimate the effect of climate change on storage losses. The storage loss data include importance of different pests (maize weevils and larger grain borer), and farmers’ estimates of storage loss due to both pests, in grain and cobs. The climate data include temperature (from WorldClim) and relative humidity (from CHIRTS) over the storage season in 2011.

Can I speak to the manager? The gender dynamics of decision-making in Kenyan maize plots
Rachel Voss Zachary Gitonga Jason Donovan Mariana Garcia-Medina Pauline Muindi (2023)
Gender and social inclusion efforts in agricultural development are focused on making uptake of agricultural technologies more equitable. Yet research looking at how gender relations influence technology uptake often assumes that men and women within a household make farm management decisions as individuals. Relatively little is understood about the dynamics of agricultural decision-making within dual-adult households where individuals’ management choices are likely influenced by others in the household. This study used vignettes to examine decision-making related to maize plot management in 698 dual-adult households in rural Kenya. The results indicated a high degree of joint management of maize plots (55%), although some management decisions—notably those related to purchased inputs—were slightly more likely to be controlled by men, while other decisions—including those related to hiring of labor and maize end uses—were more likely to be made by women. The prevalence of joint decision-making underscores the importance of ensuring that both men’s and women’s priorities and needs are reflected in design and marketing of interventions to support maize production, including those related to seed systems, farmer capacity building, and input delivery.
