Reliable weather information allows farmers to maximize their productivity and governments to implement preventative disaster management and effective public health measures. However, many of the world’s poorest people have no access to this basic, most valuable tool. An estimated 700 million poor people in rural Africa alone are negatively affected by this missed opportunity. This is especially worrisome given recent changes in weather patterns, due to climate change, which are compounding the problem by making traditional farming practices and indigenous knowledge obsolete, and increasing the frequency and intensity of severe weather.
