Speech Title : Heavy Metal Contamination Assessment of Phosphogypsum Waste from Mdhilla (Gafsa, Southern Tunisia): Pollution Indices and Implications for Sustainable Environmental Management.

Amor Ben Garali holds a PhD in geological sciences, specialising in geochemistry, sedimentology, and environmental sciences. He has been an assistant professor at the Faculty of Sciences of Gafsa since. His research focuses mainly on coastal dynamics and management, metal pollution and contamination in marine and lagoon environments, soils, and phosphate industry waste, as well as the hydrogeochemistry of groundwater. He also has extensive experience in teaching, student supervision, and scientific research. He has published several studies on metal contamination in soils and phosphate-related waste in southwestern Tunisia, as well as a book dedicated to the sedimentological and geochemical study of Bizerte Lagoon.

Speech Title : Advances in Soil Water Vegetation Carrying Capacity

Dr. Zhongsheng Guo studied soil sciences at Northwestern A & F University, China, and graduated with an MS in 2000. He then researches the high-quality and sustainable forest, grass, crop and soil and water conservation method in Northwestern A & F University, CAS & MWR. He received his PhD in 2004 at Northwestern A & F University. He obtained the position of a Professor at Northwestern A & F University, CAS & MWR. He has published several research articles in SCI(E) journals. He proposed the resource use limit by plants (RULP), vegetation carrying capacity (VCC), the critical period of plant resource relationship regulation, and the new soil and water conservation theory.

An inquisitive researcher with demonstrated skills in the domain of sustainable water management and climate-resilient practices. I am currently pursuing my doctoral studies at Cranfield University, United Kingdom. My work focuses on studying the underlying interactions amongst power, stakeholders, institutions, socio-cultural practices and environmental factors shaping the health and quality of rivers. With a Master's degree in Water Policy and Governance from Tata Institute of Social Sciences, Mumbai, my thesis focused on ways of sustainable river managment through studing altered environmental flows and its impacts on socio-economic factors of the fishing community in the Lower Damodar River Basin. This exposure along with my experience of working as a Research Fellow on different international projects at Indian Institute of Technology (IIT Roorkee), helped me strengthen my skills in research methods and writing . Furthemore, my stint of 3 years at World Resources Institute opened great avenues for me to work on the urban water resilience domain, focusing on alternate practices to ensure water security, working with communities and governance institutions as well as with government and policymakers.
