[[Rainwater Harvesting]] has proven to be an effective and sustainable solution to overcome or reduce water shortages all over the world. Especially in the light of climate change, population growth and increased pressure on natural water resources, rainwater is becoming more and more attractive as an alternative water source.

===Mapping the Potential of Rainwater Harvesting===
'''How does this work?'''<br>
The guiding principle with adding weights is that you give higher weights to the more relevant datasets in your study. For example, when your study focuses on reaching the most remote populations in the region, the suitability class for “population density” will get a lower weight. The weights that should be assigned to the datasets need to be between 0 and 1. Remember that the sum of all weights is always 1one.
The results of this scoring analysis are two maps: one with the need for Rainwater Harvesting and another for the potential success of implementing Rainwater Harvesting. Together, these form the basis for the third step.
