Replication Data for: Marando Bora Decentralised Vine Multiplier Study (Tanzania)

The implementation of the large- scale planting material dissemination component, “Marando Bora” (better vines) aimed to develop and test cost effective sweetpotato variety distribution models at scale. Marando Bora had a target of reaching 150,000 farmers with quality planting material of existing local and improved varieties which will contribute to strengthened food security. The survey of decentralised vine multipliers (DVMs) was conducted as part of the Marando Bora project end line survey. The objectives of the DVM module were to: determine use of different technologies which had been promoted by the project; obtain feedback on varieties preferred by the DVMs and their clients; and feedback on participation in the pilot Quality Declared Planting Material (QDPM) inspection scheme. Finally, we sought to understand what vine multiplication activities the DVMs were continuing after the end of the project, and their reasons for continuing or not continuing vine multiplication. Key variables include: DVM location, type (individual, group), current multiplication practice, technologies (irrigation, rapid multiplication techniques, fertiliser), experience with seed inspection. All 89 DVMs were interviewed by one data collector, February-March 2013. Data was entered in MS Excel.

About the project

Project title: Decentralized System for Community-Based Seed Production and Extension Provision

Project abstract


Unavailability of quality seed of commonly grown crops was one of the priority constraints to increased agricultural productivity identified during the PCA. It is the aim of this activity to develop a system whereby this bottleneck can be addressed in a sustainable manner, as far as possible relying on private initiative and community interest rather than be dependent on extension / input support provided by BoAs line agencies and/or NGOs. The approach will work closely with the Model/Lead Farmer concept (1 to 5) which is widely promoted by the GoE with a Farmer Field School (light) approach, that promotes farmer-to-farmer extension.

Dataset for: The Viable Sweetpotato Technologies in Africa (VISTA)-Mozambique: Endline survey for Nampula and Zambezia Provinces

The endline survey for Viable Sweetpotato Technologies in Africa (VISTA) project in Mozambique was conducted in November-December, 2018 in 15 districts: 11 in Nampula province (11 districts in Nampula Province (Nampula City, Rapale, Murrupula, Malema, Mecuburi, Meconta, Monapo, Mogovolas, Moma, Larde and Angoche) and 4 in Zambezia Province (Alto Molocue, Gurue, Mocuba and Gile). The survey covered 1, 538 households from these 15 districts. A multi-stage sampling procedure was used in selecting households for the study. The first stage involved stratifying the 15 districts into two strata: the pilot districts that were first to be exposed to the intervention from 2014 and the expansion districts that were exposed from 2016. The second stage involved the random selection of the intervention and control villages from the list that was identified by the project staff and local agriculture and health extension officers at the beginning of the project. Once the villages were selected, the households from these villages who were among the 2,955 households interviewed during a baseline survey in 2015 and follow-up survey in 2017 were listed to create as the sampling frame from which the 1,538 households for the 2018/19 survey were randomly selected. This way, the households interviewed in previous surveys were revisited in the 2018/19 survey providing the opportunity to understand farmer experiences with OFSP and adoption, retention and dis-adoption patterns. The number of villages per district and households per village was proportional to size. A structured household survey was used for data collection. The questionnaire had several modules including household socio-demographic characteristics; crop production and sales; knowledge, attitudes and practices on sweetpotato; preferred attributes for sweetpotato varieties; growing of OFSP in previous and current seasons; nutrition and vitamin A knowledge; intake of vitamin A rich foods including OFSP, dietary diversity and food security status.

Dataset for: RTC-Action Malawi Project Baseline study for Potato Component

The baseline study was conducted to assess and understand the socio-economic situation of farmers including potato production methods and technologies, seed system, input and output market systems, farmer capacity levels, perception on potato nutrition issues and food security situation. The results show that potato production is mainly dominated by female headed households in the new districts (Dowa and Mzimba) mainly because the crop is relatively newer but slowly getting popularity due to the declining tobacco performance that has been the number one cash crop in these districts. The average age of the sampled household heads was 34 in all the districts and this result indicates that the potato production is mainly dominated by people who are still in the productive age. This observation is consistent with the fact that potato production is relatively labour intensive hence it requires participation of active adults and the youth. Further to this, the results show that on average the households have a total land size of 1.5 acres (0.6 ha) which is consistent with the results of the recent IHS 4 that also reported that on average in Malawi, the average cultivated area is about 1.5 acres and further results also show that on average, male-headed households cultivated 1.7 acres compared to their female counterparts who cultivated 1.2 acres.

Participation of Women Farmers’ in the Agricultural Research Process, Ethiopia

Quantitative data collected to understand the level of women farmers’ participation in four agricultural research processes – design, testing, dissemination, and M&E. Data were collected in four woredas (districts), within the Ethiopian highlands (i.e. Basona Worena, Sinana, Lemo and Endamehoni), located in the regions of Amhara, Oromia, Southern Nations Nationalities People (SNNP) and Tigray respectively. Data were collected from women farmers who participate in the Africa RISING project and those who did not participate in the project.

Making Seed Systems and Markets for Vegetatively Propagated Crops (VPCs) Work for the Poor: A Cross-Country Study of Kenya, Nigeria, and Vietnam

Many developing-country farmers cultivating vegetatively propagated crops (VPCs)—crops such as cassava, potato, sweetpotato, and yam—face constrained access to quality planting material. This challenge is distinct from the challenges facing cereal crops, and is associated with both the unique biological and economic nature of vegetative propagation. Although technological solutions exist, there are other limiting factors relating to policies, institutions, and markets that shape VPC seed systems, e.g., quality assurance mechanisms, certification regulations, sanitary and phytosanitary standards, and plant variety protection.

This research project aims to provide actionable evidence on policy and investment options to accelerate seed system and market development in countries where VPCs are important to food security and agricultural development. By taking a collaborative and multidisciplinary approach to the research, the project (1) analyzes current policy initiatives and success factors underpinning models that incentivize cost-effective multiplication and distribution of VPC seed to smallholders; and (2) develops a set of crop-specific case studies in Kenya, Nigeria, and Vietnam that encourage closer consideration of more appropriate policy options. This document provides a brief summary of the project and accompanies the key informant interview guides to collect data for analysis purposes.

Replication data for: Demand of high quality seed in Ecuador

The use of high quality seed is one of the current strategies to increase seed and food security in the highlands of Ecuador. Unfortunately, poor information about farmers’ demand of high quality seed limits the implementation of this strategy. For this reason, this study aimed to investigate the characteristics of the demand of high quality seed in the country. To do this, 150 potato producers were surveyed using the rapid market assessment in five Ecuadorian provinces: Cañar, Carchi, Chimborazo, Cotopaxi, and Tungurahua (data in “survey_answers1” and “survey_answers2” sheet). Also, 13 interviews were carried out with experts that are involved in the seed value chain (data in the sheets referring to interviews and in the report associated to this study).

Dataset for: Endline Survey: Jumpstarting Orange-fleshed Sweetpotato in West Africa through Diversified Markets

Jumpstarting Orange-fleshed Sweetpotato in West Africa through Diversified Marketsis was a three-year project that partnered with a diversity of NGO and public sector actors to target both informal and formal markets in 3 countries of Ghana, Niegeria and Burkina Faso. We worked towards four major outcomes at each target location: 1) to establish commercial sweetpotato seed systems to provide clean planting material year round, 2) to develop formal and informal markets for OFSP, 3) to enable farmers including women, to participate in OFSP value chains and 4) to increase consumption of OFSP and other vitamin A-rich foods by vulnerable target populations, particularly women and children under the age of five. By conducting awareness and demand creation campaigns at the local level and advocating for OFSP for food and nutrition security at all levels, demand is created in both formal and informal markets. In each area, building capacity to achieve project outcomes was a key element of project activities, as is building the partnerships to ensure and replicate success. In order to measure achievementsmade, an endline survey was conducted after the project interventions

Participatory Variety Selection of Wheat, Barley, Broad Beans and Potato Combined with Double Cropping of Short Duration Crops

This data study contains data related to participatory variety selection (PVS) and double cropping of cereals, broad beans, and potato


About the project

Project title: Second Agreement Africa RISING (Research in Sustainable Intensification for the Next Generation: ILRI Contract No. ASSP-14/2014

Project abstract


The Ethiopian highlands are characterized by cereal-food legume production system where the productivity is very low due to pests, poor agronomic practices and growing of unimproved cultivars. Potato is becoming an integral parts of the production system of the highlands. Sustainability of cereals (wheat and barley) and potato is maintained through regular rotation with food legumes in small and main rainy seasons of the highlands. During the implementation of Africa RISING (AR) in Bale highlands and other projects, it was possible to identify high yielding cereal, broad beans and potato cultivars that can provide high yield and contribute to food security. However, many varieties are not tested in all the four AR sites. Moreover, there are early maturing legumes that can be used in double cropping with cereal and potato to increase land productivity in the highlands. Most of the wheat, barley, potato and broad beans cultivars released are developed with little or involvements of farmers and hence there is a need to put these varieties under PVS where farmers’ inputs will be considered. Therefore, this study/intervention is designed to evaluate cultivars of the four commodities following PVS approaches as well as testing double cropping to increase land productivity.
