Introduction

Much of Uganda’s agriculture is rainfall dependent. However, due to climate change and variability, crop growing seasons have shown more erraticism in onset and length of growing period, often resulting in reduced yields or total crop failure. In response to this, Uganda National Meteorological Authority (UNMA) periodically provides seasonal climate forecast. The forecast has been found to be limited in interpretation, understanding and use by stakeholders and consequently with support from GIZ and USAID, the National Agricultural Research Organization (NARO) has developed an online cropping calendar tool that would contribute towards stakeholder’s interpretation and understanding of a forecasted season.
