Baccalaureate National Exam 2021 July Sciences
 “Everyone was leaving the village where | grew up, and it was all because of water shortage,” says Jamila Bargach. Her village in Sidi Ifni in rural Morocco has known severe drought. However, this region has one precious resource: fog. “We began to read about fog collecting projects around the world, and we decided to try it here as we have on average 143 days of fog a year,” says Bargach.
 The fog is caused by a unique microclimate. The air turns into heavy fog, particularly between December and June. For years, the community saw this as a bad thing: they believed the fog prevented rainfall and made people sick.
 The fog collecting project in Dar Si Hmad consisted of using nets to capture the fog at an altitude of 1,225 m on the top of Mount Boutmezguida. About 6,300 liters of water can be collected daily. The water is then filtered and mixed with underground water before it reaches 400 people in five villages through 8km of pipelines.
 The benefits of the project are obvious: clean water is instant and free for the population. “We used to spend at least five hours going to collect water every day in neighboring villages. This made it very difficult for us to go to school because it’s just accepted by everyone that it’s a woman’s job to go and get water,” says Zeyna Hamou, a local woman who works as a coordinator for Dar Si Hmad project.
 The idea of collecting fog was first developed in South America in the 1980s and there are other projects in the US and Africa. Dar Si Hmad is planning to install the next generation of fog nets, developed in Germany. These larger nets will double the amount of water collected and connect other villages to the network.
 In recognition of its contribution to finding solutions to climate change, Dar Si Hmad was awarded the 2016 UN Momentum for Change award. The project members traveled to receive the award at the COP22 climate change conference in Marrakech.
