Dr. Zahir Ahmad is serving as a Lecturer in the Department of Geography & Geoinformatics, The Islamia University of Bahawalpur (IUB), Pakistan. He holds a PhD in Mountain Geography. His research focuses on climate change impacts on water resources, mountain ecosystems, mountain agropastoralism, deforestation, glacier recession, biodiversity conservation, livelihood sustainability, and environmental sustainability, particularly in the Hindu Kush–Himalaya and arid regions of Pakistan. His expertise includes Geographic Information Systems (GIS), remote sensing, GeoAI, GEE, spatial modelling, and machine-learning techniques for environmental assessment. His research interests include climate change assessment, cryosphere and glacier dynamics, groundwater depletion, drought monitoring, GLOF risk, rainwater and snowmelt harvesting, land-use/land-cover change, deforestation, endemic flora conservation, mountain agropastoralism, livelihood sustainability, GeoAI-driven environmental modelling, and climate-resilient resource management. He is actively engaged in interdisciplinary research integrating geospatial technologies, artificial intelligence, environmental modelling, and sustainable development to support evidence-based environmental planning and resilient livelihoods.
