Many areas in Namibia have very few water sources, even if it rains enough for vegetation at times. Standing water in the form of a puddle must be protected by a roadblock and serves as a natural watering hole for wandering animals. Passing traffic must make a detour.

In the past decade, the Indonesian government has constructed a massive wall along Jakarta’s 46-kilometer coastline, with some sections reaching as high as 10 meters. This sea wall aims to protect the city from the threat of rising sea levels. The mosque located outside the wall is gradually sinking into the sea.

Numerous artificial trickling fields have been set up close to Berlin to examine the possibility of removing residual pollutants like phosphates, detergents or drug residues from wastewater through natural purification. This process is achieved through the extended time the water remains in the system.

In recent years, forests in Germany have been massively affected by tree mortality. The targeted conversion of forests –especially pure coniferous forests to mixed forests– can help more precipitation water to seep away and support natural groundwater recharge.

In Namibia, a traditional house is built with several rooms arranged under the open sky. All family members have small covered bedrooms. The kitchen area is also covered, but it has an open-air fireplace. The toilet is located outside the house, and there is a small extension without a roof that serves as a shower.

Many residents of Namibia face the challenge of traveling long distances to access water sources, as there are only few wells available. However, with the aid of various subsidies, groundwater wells are being constructed throughout the country. These wells are equipped with hand pumps, making it easier for people to access water.

In Jakarta, all the river courses have been artificially laid out to create space for human habitation. This results in flooding during heavy rainfall, as the rainwater cannot run off or seep into the ground-water quickly enough.

Over the past four years, Germany has seen a rise in the frequency of forest fires during the summer months. Risk studies conducted by the Federal Environment Agency suggest that the risk is increasing significantly due to changes in precipitation. This is particularly concerning as forests make up one third of the country’s total area.
