### Kinshasa under waters: an emergency for rainwater management
The city of Kinshasa, capital of the Democratic Republic of Congo (DRC), was recently struck by torrential rains that caused catastrophic floods. On April 4 and 5, water torrents swept through the city, causing fatal landslides in several districts. The consequences of these bad weather do not only affect the daily life of the inhabitants, but also underline a crucial question: how can the DRC improve its rainwater management to avoid such tragedies in the future?
####
Kinshasa, with its population which exceeds 12 million inhabitants, is experiencing rapid urbanization which exerts unprecedented pressure on its infrastructure. Large rains, combined with poorly planned urbanization and a lack of adequate infrastructure, create an explosive cocktail. The Ndjili river, which defines the landscape of certain municipalities, chases the inhabitants each year during rain seasons, highlighting the urgency of developing effective drainage systems.
Traffic on Boulevard Lumumba was seriously disrupted for more than 48 hours, affecting not only transportation but also the local economy, already weakened by other factors such as insecurity and a deficient public service offer.
#### The crucial role of remote sensing
It is in this context that space sciences emerge as a precious tool for rainwater management. Professor Albert Kabasele, a climate remote sensing specialist, evokes the importance of using satellites to monitor water behavior and risk areas in real time. By analyzing satellite data, it becomes possible to map vulnerable areas, anticipate floods and take preventive measures.
Remote sensing also makes it possible to assess the capacity of existing infrastructure to manage rainwater. For example, monitoring climatic and hydrological variability can help model future scenarios, thus facilitating more resilient urban planning.
### towards sustainable rainwater management
To prevent such incidents in the future, Kinshasa must imperatively consider an integrated rainwater management approach. Here are some strategies that could make the difference:
1. ** Sustainable infrastructure **: Invest in modern rainwater management infrastructure, such as retention tanks, improved drainage systems and green spaces that promote infiltration.
2. ** Awareness and education **: involve communities in awareness programs on the importance of drainage systems and associated behaviors, such as cleaning gutters and waste management.
3. ** Responsible urbanization **: Avoid construction on flooding land, establish urban planning plans that take into account the risk of flooding, and encourage more dense and lasting urban development.
4. ** Public-private partnerships **: involve the private sector in the implementation of innovative solutions for rainwater control, such as intelligent drainage technologies, which can adapt to precipitation variations.
#### Conclusion
Kinshasa’s floods alert the need to act quickly and effectively. Rainwater management is not only a question of infrastructure, but requires political will, sustainable urban planning and a collaborative approach involving all the actors concerned. With modern recognition and analysis tools, such as remote sensing, the DRC can consider a future where natural disasters will no longer be synonymous with human and economic losses. Such an approach is essential to transform Kinshasa of a vulnerable city into an example of resilience in the face of climatic challenges.
