Mark Jwaideh

Mark is part of the Water and Food Resource Nexus research theme at UCL led by Dr. Carole Dalin. His thesis project is to identify the global environmental impact from crop production through the development of a composite indicator, to aid decision making for long term, multidisciplinary policy and research programs. Mark’s research takes advantage of new spatially-explicit estimates of environmental impacts of global agriculture due to the use of fertiliser, water, land-use and emissions of greenhouse gases. Different constructions of a meaningful composite indicator are formed and assessed for their sensitivity to varying biophysical and resource input factors.

This thesis additionally has a strong focus on environmental impacts from fertiliser-use, which develops methods to model fertilisers and their adverse interaction with the environment. Life Cycle Impact Assessments (LCIA) are often used to determine the impacts of fertiliser-use but lack suitable methodologies to estimate the fate and transport of nutrients from soils, making crop and regional impact comparisons difficult to assess. The research develops a spatially-explicit nutrient fate and transport model to be used within an LCIA frameworks. This research identifies the global spatial-variability of nutrient loss from fertilisation of crops and their relative impact on biodiversity, specifically species richness with fresh and marine water environments.


Mark is also currently a flood risk consultant for local authorities within London supporting them on their flood risk management strategies and statutory policy commits to provide technical advice on surface water drainage for major developments. 

Prior to UCL ISR, Mark was a visiting researcher for the WHO Collaborate at Imperial College London, conducting research into the link between water management and infectious diseases in the Middle East.  In the private sector, Mark was a flood risk consultant for three years, after having obtained his MSc in hydrology and water resource management from Imperial College London and his BSc (Hons) in physical geography from Kings College London.

Marks skills and experience within the private, public and academic settings has given him interest in surface water management and runoff, water scarcity, contaminant and nutrient modelling, global food production and environmental indicators of sustainability.
