Weather Forecasting Display Board: Atuilia weatherboard.

This Weather Forecasting Display Board (WFDB) is both attractive and useful to the local community, especially to those who are vulnerable to flooding and other climatic disruptions.

The results of the first pilot study show that rural people working in agriculture and shrimp farming found it very helpful.  Coastal areas like Atulia of Shyamnagar, Satkhira district and Zhilonga Union in Cox’s Bazar District are highly susceptible to cyclone and water surges, so found it very useful for their daily livelihoods.  It was scaled up at Sirajganj Sadar Upazila, a disaster prone area where flood and river bank erosion occur frequently.

Shyamnagar Upazila, is a climatic hotspot and the majority of the people are manage their livelihood by shrimp farming. This Weather Board was first demonstrated at the Atulia Union Council of Shyamnagar Upazila in 2011.

How does it work?

  1. Construction: A wooden frame with CI sheet and covered by transparent either glass or white plastic where clear, concise daily weather messages are interpreted with well-known symbols
  2. Function: If somebody doesn’t understand the messages on the board, they ask the Gyaner Haat people (Entrepreneur of Knowledge node at community level, Union Digital Centre) for an interpretation.  This helps them to understand about the implications of the messages of the board and what action they should take.
  3. Content:  Weather and climatic information are displayed like daily temperature, rainfall, humidity and sunlight hour along in attractive and relevant ways.
  4. Scientific Information is carried at local level:  Information is collected from the Bangladesh Meteorological Department (BMD) on current weather issues on a regular basis and interpreted on the Weather Forecasting Board for three weeks. It also provides agricultural information for farmers proactively like suitable crops variety during that time for planting, whether farmers should go for raising a seed bed, or releasing fries in the gher etc. in the current week.
  5. Link with extension agents:  The board includes necessary mobile phone numbers/contact persons of relevant government departments, so that farmers and fishers can make phone calls to Gyaner Haat and concerned  government professionals for necessary information and advice.

Digital display of weather forecasting  and flood early warning

Digital weather boardPractical Action trialled this  manual display board for access to weather and early warning information for reducing loss and better farming preparedness. This was a very low cost solution but effective. Now a day’s supply of electricity and internet connectivity has been expanded through a government Access to Information program (a2i) that is called Union Digital Centre.

Practical Action in partnership with a2i project has installed a knowledge service branded as Gyaner Haat. In each Gyaner Haat there is an entrepreneur who has a computer, printer and internet connection. We get national weather and flood forecasting information from government authorized sources (Bangladesh Meteorological Department and Flood Forecasting Centre)  and these are translated into local dialects along with descriptive information for the farmers.  Information such as what they will do if the vapor level is high, what would be the effect of higher humidity enables farmers to make better preparation. The digital board allows easy and rapid information delivery at community level and thus contributes to saving poor people’s assets and resources.

We are implementing this in the Sirajganj and Bogra districts, two of the most flood prone areas , which are recurrently attacked from flood during the monsoon season from July to September. This has been empowering knowledge poor people to benefit from forecasting and disaster preparedness. It is one of the knowledge intervention activities of the Zurich Flood Resilience Project in Bangladesh.
