Whether you work in the field or at headquarters, with a UN agency or an NGO, whether you plan for emergencies, respond to them, or design the most appropriate programmes possible, we hope WFP's Seasonal and Hazards Calendar will be a great help to you. It was specifically developed by WFP's Emergency Preparedness and Response Branch as a tool for sharing as widely as possible within the humanitarian community.

The calendar combines the most authoritative information on major seasonal hazards like floods, droughts, cyclones and the prevalence of pests like locusts, alongside crop growing cycles, rainy and lean seasons.

Just clicking on a coloured box you'll immediately have the information you need, such as the details of a season or staple crop, the list of main historical events occurred with areas and number of people affected, in order to extract relevant indicators of the occurrence of those events, the areas most commonly affected alongside the potential damage to crops when a natural disaster happens.

This online platform was developed with a rigorous approach to the reliability of information sources and a firm belief that it had to be as appealing and user-friendly as possible. The calendar covers the 82 countries where WFP has operations, including the world's newest, South Sudan, but we are already working to expand it to another 20 oversight countries considered to be of interest for humanitarian actors.

In its testing phase it was the basis for preparedness plans in Haiti ahead of the 2010 hurricane season. But when the earthquake struck first, the very flexible calendar was instead put to use identifying disruption to the agricultural cycle.

You will be also able to download the excel and PDF files and export the information in your own system. If you have comments or suggestions, you can contact us.
