Dam failures are likely to become even more common with the unpredictable rainfall caused by climate change – rainfall and runoff reach levels for which the dams were not designed. This has been the case with the Bagre Dam. Models are predicting that due to climate change this kind of extreme and erratic rainfall will happen more often in West Africa. But many models also predict that drought will happen more often – the models disagree. This is a geographical area that scientists working with models find very frustrating – they cannot agree on what will happen; will there be more or less rain? The water level in the Bagre Dam is near to impossible to manage in order to optimize water usage options in Burkina Faso – and downstream in Ghana. Similarly, whether the local people living in this area will be most successful planting fields nearby the river, or further away, is a matter of luck. The question of whether the benefits of a dam outweigh its potential costs is thereby further amplified with the unpredictability that comes with climate change.
