Aracelly Mallma's thesis, "A Review on the Mean and Extreme Precipitation Changes over Pakistan," was supervised by Prof. Dr. Jürgen Böhner (Professor of Physical Geography, Universität Hamburg) and Dr. Shabeh Ul Hasson (Interim Professor at University of Hamburg). 

This study employed the Systematic Literature Review (SLR) approach to analyze Pakistan's mean and extreme precipitation trends. The review, covering 112 articles from 2000 to 2023, highlighted significant variability in dataset selection across regions, complicating long-term trend analysis. Methodologies showed a gradual shift from traditional techniques like Linear Regression (LR), Mann-Kendall test (MK), and Sen Slope (SS) to advanced methods such as Innovative Trend Analysis (ITA). Furthermore, inconsistencies in defining the monsoon season and regional divisions in Pakistan added to the complexity of results.

Despite these challenges, the study found mixed precipitation trends in northern Pakistan, with Khyber Pakhtunkhwa (KP) and Southern Punjab (SP) generally showing increases, while southern regions like Balochistan and Sindh experienced significant decreases, particularly in extreme events. The findings underscore the need for more consistent methodologies and careful dataset selection to improve the reliability of future analyses.

Aracelly's future plans include advancing her expertise in data management and climate change, aiming to work for companies that require these skills. We wish her the best in her endeavors.
