Over 1,500 data scientists have collaborated to develop artificial intelligence (AI) models capable of detecting diseases in Ghana’s key crops, such as pepper, tomato, and maize. 

FAIR Forward, a German development cooperation initiative implemented in Ghana, bolstered food security, supported farmers, and promoted the open and sustainable use of artificial intelligence. It forms part of the German government’s AI strategy. 

This project, spearheaded by the Federal Ministry for Economic Cooperation and Development (BMZ) and implemented by Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH, aligns with Ghana’s broader national AI strategy, which aims to transform sectors, including agriculture 

The initiative targets Sustainable Development Goal 2, which focuses on achieving zero hunger by leveraging AI to effectively predict and manage crop diseases.

The Ghana Crop Disease Detection Challenge attracted 344 participants who submitted models, reflecting a vibrant innovation ecosystem. 

The competition culminated in an ecosystem event held in Accra, where winners were awarded cash prizes for their lightweight, offline AI models that can operate in resource-constrained environments, critical for smallholder farmers. 

These models offer precise disease identification, enabling timely interventions to reduce crop losses and improve yields.

Experts at the event emphasised the importance of collaboration and continuous innovation. Prof. Nana Ama Browne Klutse, Vice-Chair of the UN Intergovernmental Panel on Climate Change Working Group, highlighted AI’s role in climate resilience and urged inclusive approaches involving women, youth, and smallholder farmers. 

Challenges such as data quality and resource limitations were acknowledged, and calls were made for strengthened partnerships and centralised data repositories to enhance AI’s impact.

This initiative demonstrates how AI-driven solutions can address pressing agricultural challenges in Ghana and Africa, fostering sustainable food systems and empowering farmers through technology.

The open-source availability of these AI models invites further exploration and development, positioning Ghana as a leader in smart agriculture innovation on the continent.
