Choice Experiment to Understand Farmer Preferences for Technology Adoption

No comments

ACAI is carrying out a choice experiment exercise that is meant to help the project team understand the socioeconomic factors that influence cassava farmers’ readiness to adopt and use the decision support tools that the project is developing.

Audrey Vanderghinste from the University of KU Leuven explains choise experiment design to Dr Pieter Pypers, Bakari Kidunda and George Sonda

The experiment is a joint initiative between IITA, Tanzania Agricultural Research Institute, TARI, and the University of KU Leuven, Belgium. In the course of September and October, enumerators working with ACAI IITA staff and partners will participate in collecting data at household level from farmers working with ACAI.

Results from the experiment are expected to help the project predict and drive an efficient adoption campaign. The experiment will be looking at farmers’ willingness to intensify cassava farming and the motivation behind the willingness. The participating farmers will be taken through prepared choice experiment to select cassava growing and selling options under different circumstances with varying positive and negative outcomes.

Dr George Sonda from Tanzania Agricultural Research Institute Ukiriguru, shows the choice cards to a cassava farmer in Mkuranga, Tanzania where ACAI performed the test trial of the experiment.

ACAI is pioneering the choice experiment as a technique that will inform critical and strategic decisions for development of the dissemination strategy. Dr Pieter Pypers, IITA’s senior Agronomist and the ACAI project leader says it is “important to gain an insight into the demographic characteristics of the targeted population in order to package the decision support tool based on the finding.”

Choice experiments are famous for introducing new products in the market with a very high success rate for predicting and estimating customer behavior. ACAI is developing six decision support tools aimed at addressing specific challenges facing cassava grower that will be rolled out in Nigeria and Tanzania before finally being scaled to Ghana, DR Congo and Uganda.

To prepare for the exercise, ACAI project team held a workshop in Dar es Salaam with a team of social economists from the Tanzania Agricultural Research Institute, TARI, to craft the choice card for use in the experiment and to develop the work plan for the exercise.  Leading the workshop was Dr Pypers and IITA’s systems agronomist Dr Veronica NE Uzokwe  who is  also ACAI coordinator for East Africa. Others at the planning workshop included Audrey Vanderghinste from KU Leuven, Dr George Sonda from TARI, Ukiriguru station, Laurent Aswile from Illonga and and Bakari Kidunda from TARI Naliendele research station in Mtwara.

The exercise will start officially on the 26th of September engaging a number of households that ACAI has on the baseline study database.

ACAI holds Training of Trainiers to kick off DST validation in Tanzania

No comments

ACAI held a training of trainers for the Tanzanian development partners in August to kick off the validation of the ACAI decision support tools in the country.  The training was organized to create a better understanding of the ACAI use cases in Tanzania, the process of effectively evaluating the decision support tools (DSTs) and teaching reliable means of collecting feedback. This was the first step toward the planned capacity building for the project partners to carry out the validation exercises.

IITA’s senior Agronomist and ACAI coordinator for East Africa Dr. Veronica Uzokwe led the training; outlining the project approved standard protocols to be used for site selection, layout of the fields to be monitored during the validation and inputs to be used in the trial fields.

The two-day event was held in Mtwara, the southern Zone of Tanzania on the 14th and 15th of August 2018 with 37 people in attendance. Participants drawn from organizations partnering with ACAI in Tanzania including CAVA-II, FJS Starch Development Company, MEDA and MINJINGU Fertilizer received practical training on using the current version of the ACAI DSTs and the methodology of how to train extension agents and farmers to implement the validation exercises.

ACAI is targeting to reach more than 500 farmers in Tanzania for the validation of the DSTs using 40 extension agents pooled from the network of development partners. During the validation, farmers will run a side by side comparative cropping of their normal cassava farming practices against a plot within their fields where ACAI recommendations will be applied based on the tool that is applicable.

The project is running validation trials in the farmer’s fields for the Scheduled Planting Recommendation decision support tool (SPT), Site Specific Fertilizer Recommendation decision support tool (FR) and the Intercropping recommendation decision support tool.

Each of the partners is expected to carry out step down trainings in their respective extension networks and are tasked to monitor the extension agents they will have trained to ensure a successful implementation of the validation process for the DSTs.

Dr Desudedit Peter Mlay from the Tanzania Agricultural Research Institute, TARI, led the discussions that drew a schedule of planned activities starting from the onset of the new planting season in September.

Each partner is responsible to coordinate their extension agent network, to communicate to them the expectations from the project and maintain a close relationship with the farmers under their scope. ACAI has also developed an incentivized trial monitoring and data collection system that encourages spirited involvement of EAs and lead farmers, reward their efforts and appreciate their contribution to the project.

ACAI is carrying out validation exercises to test the version one of the decision support tools that the project has been developing. The validation kicked off in Nigeria early 2018 with similar trainings followed by step-down trainings at state and partner level.

Results and feedback from the validation exercises will be incorporated into further development and improvement of the second version of the decision support tools to improve their prediction and recommendation

 Farmers participate in the sampling of maize harvested from an Inter-cropping Validation trial plot

ACAI development partner in Anambra state in Nigeria, Sasakawa Africa Association (SG2000) organized farmers’ field days to show case the results from ACAI research and validation trials within three local governments in Anambra state between July and August 2018.

SG 2000 working closely with the National Root Crops Research Institute NRCRI brought together more than 30 farmers from three out of the four Intercropping (IC) validation clusters in Anambra state to learn from one of the lead farmers carrying Intercropping trials for maize and cassava under the ACAI project.

Chris Okoli, SG2000 state coordinator for Anambra organized the event due to what he referred to popular demand from the farmers he has been in interaction with who are interested in the ACAI activities.
While farmers in the area commonly plant their crops on mounds without specific densities and fertilizer regime, ACAI has been carrying out trials to establish the most suitable planting densities, fertilizer regime and land preparation to maximize yield from both crops.
“When neighboring farmers pass by our trials, they are mesmerized, and always ask when we can bring them to our plots and teach them our procedures, that is what we have done now.” Said Chris Okoli, SG2000 Anambra.

In the South East Nigeria, cassava is predominantly intercropped with maize. In 2018, ACAI through its partners is running side by side comparison validation trials to show test the efficacy of the intercropping recommendation decision support tool.
The field days were held on three different days to demonstrate the proper intercropping practices for Maize and cassava, giving spacing dimensions, advice on land preparation, planting dates and the harvest dates and a show of the probable results to be expected from following the IC recommendations.
These were the first field days of the project since the beginning of the validation exercises in Nigeria earlier in the year. The first farmers field day was held in the farm belonging to Mrs Catherine Kenechukwu’s in Umunze, Orumba South local government of Anambra State, Nigeria in July 17th 2018. This was followed up two other field days on the 27th and 28th of August hosted at Offia – Oji Vilage in Dunukofia local government and Ubru in Orumba North local government respectively.

Farmers who participated were impressed with the fields the visited noting the increased plant population and the amount of the maize harvested from the plot in comparison to their practice. The farmer’s response to the trials and ACAI regime of agronomy practices is important especially as the project gets ready for the dissemination phase of the technologies that have been in development.
Festus Arinze, a farmer who works with ACAI in Orumba North local government hosted on of the field days. He implored his peers to emulate his practice and adopt ACAI intercropping recommendations to achieve similar or better results as witnessed in his farm.
ACAI will be hosting similar events to encourage adoption of the DSTs at an early stage and for farmers to participate in the evaluation of the tools that help improve their delivery and recommendations.
