Canoa de Tolda
For the first time in the region, data was collected in high-precision, collaborative digital terrain modeling to enable the mapping of populations in areas at-risk of flooding. Canoa de Tolda Project aimed to train local people from the lower stretch of São Francisco River basin to collect data.

The region has been suffering from the impacts of climate change, with drastic periods of drought and flooding. The increase in the frequency and intensity of droughts can cause perennial rivers to become intermittent. Intermittent rivers can disappear. Similarly, heavy rains and the lack of urban planning put communities that directly depend on the river for basic socio-economic activities at risk.
