For poor countries, building weather and hydrological services to produce reliable forecasts often does not appear as a priority. Such services are seen as a luxury, rather than a necessity, in low income countries. But is it really the case?
In many countries, human and economic losses caused by weather extremes are on the rise, and they sometimes increase more rapidly than wealth. In some regions, natural disasters now represent a significant obstacle to poverty alleviation at the household level (many studies show that disasters can put households in poverty traps) and at the macro level (some regions are affected by regular events and spend a large fraction of their resources for reconstruction instead of development).
