Coffee rust has menaced the global coffee industry for more than a century, but particularly in the era of climate change. Nevertheless, effective, coordinated action between coffee producing countries across Central America has remained elusive, and as a result the disease has spread—to devastating effect. In 2012 and 2013, coffee rust reduced the region’s coffee production by 15 percent, including a staggering 31 percent in Honduras. The figure below shows the losses each country suffered during that season.

According to the Inter-American Institute for Agricultural Cooperation, the decline in regional coffee production meant the loss of 265,000 jobs between 2012 and 2013, causing lasting damage to Central America’s already-fragile economies, particularly in rural areas.

To respond to the growing challenge, and to take advantage of the region’s rapidly expanding digital ecosystem, DAI—working through the U.S. Agency for International Development-funded Regional Climate Change Program—developed an application–Coffee Cloud–that would help farmers fight coffee rust and improve their crop yields.

Coffee Cloud was built using a human-centered design approach, bringing together government institutions, research institutes, and coffee producers in a collaborative, creative fashion. The application produces information specific to each farmer’s crop to facilitate data-driven decision making about the management of those crops. This app:

  • Was created with and for coffee farmers: Its design process focused on user input to create a customized, demand-driven solution.
  • Enables two-way communication: The app connects coffee farmers in real time with the government coffee institute in their country.
  • Links information generated by meteorological services and coffee institutes with the sector and individual farmers, using historical weather data for a predictive model.
  • Is a data collection tool: Farmers input information to get customized advice, and this data is taken into account by an early warning system for the entire coffee industry.

Today, Coffee Cloud is being used by more than 5,000 farmers across Central America. This white paper shares the lessons we learned building and deploying the tool, with a focus on fundamental questions of design and implementation:

  • How we decided to build an app instead of a website or other engagement platform.
  • How the functions and visual elements were chosen from a list of possibilities, through direct engagement with prospective users from government ministries to farmers in the field.
  • How we assembled a consortium of stakeholders and contributors from across government, the scientific community, agribusiness, and farmers themselves.
  • How DAI was involved, and how the consortium collaborated to leverage each player’s unique strengths.
  • How political will among governments and other partners was secured and leveraged.
