What is it about?
Rainfall is crucial in semi arid regions, as it serves as the primary water source. With climate change altering precipitation patterns, understanding these changes is essential for sustainable water management. This study investigates changing rainfall patterns in the Mekkera Basin, a semi-arid region in northwest Algeria, using an innovative analysis method called Innovative Polygon Trend Analysis (IPTA). The research examines 36 years of rainfall data from 12 meteorological stations, focusing on seasonal variations, rainy days, and extreme weather events. The findings reveal a significant decrease in rainfall during the spring months, while late summer and autumn exhibit increased instances of extreme rainfall. These patterns highlight the growing unpredictability of rainfall, posing challenges for traditional water management practices.

Why is it important?
Our work provides a timely and innovative approach to analyzing rainfall variability in a semi-arid region heavily impacted by climate change. Unlike traditional methods, the IPTA technique uniquely identifies trends without requiring strict statistical assumptions, offering a more nuanced understanding of rainfall patterns. This is crucial for regions like the Mekkera Basin, where water scarcity and erratic precipitation pose significant challenges. Our findings demonstrate two key insights: A significant decline in spring rainfall, impacting agriculture and water availability during critical growing seasons. An increase in extreme rainfall events during late summer and autumn, which can lead to flooding and infrastructure strain. These results can guide the development of adaptive strategies, such as improved water storage systems and revised agricultural practices, making our research invaluable for policymakers and environmental planners seeking to mitigate the effects of climate change.
Perspectives
Writing this article was a deeply enriching experience as it allowed me to address a critical environmental issue affecting the semi-arid Mekkera Basin. Collaborating with a team of dedicated researchers, we explored innovative methods to understand rainfall trends, a topic that is not only scientifically fascinating but also profoundly relevant to the challenges of climate change.
