Why We Exist
Background
In Tanzania, the agricultural sector, largely dominated by smallholder farming, accounts for one quarter of the national GDP, but production is stagnant, while the population is expected to double by 2050. The effects of climate change are deepening the vulnerability of agriculture to disasters. Chronic malnutrition rates are above the African average, with 32% of children under 5 being stunted.
Maize is the most important staple crop in Tanzania, used to make ugali among other dishes. Common beans also play an important role in nutrition and food security. Both crops see significant losses to pests and diseases, up to 100% on some smallholder farms. These problems can be managed, but early identification and intervention is important. Very few farmers in Tanzania are using software to identify diseases of maize or beans. However, 67,000 farmers are now using a banana disease identification app developed by the applicant team.
Approach
The project will assess needs, train and test a machine learning system for identifying diseases of maize and common beans and develop a mobile application. The mobile application will be distributed through farmer associations to reach farmers who do not own smartphones.
Targets
Current status
The NM-AIST team in Tanzania has made significant progress in their project to develop an app for identifying plant diseases in maize and beans. They have collected hundreds of thousands of images of maize and bean leaves with agricultural experts and advanced computer programs ensuring the accuracy and clarity of the data. In the next phases, the data will be used to create, develop, test, and implement disease identification models.
Role of Grow Further
Grow Further will provide a grant of approximately over 2 years to cover all research and development costs associated with the project and some agricultural extension activities. Larger-scale agricultural extension activities will be covered by government and NGO partners. In the event that the results of the project are widely adopted, Grow Further will arrange a rigorous independent evaluation to determine whether it successfully improved nutrition, farm income, and other socioeconomic variables.
Our long-term plan is to form a network of chapters or imitators so that farmers and scientists have lots of choices when it comes to testing small or unconventional ideas, and so that people who don’t work at a grant-making agency have a meaningful way to get involved.
