Why coastal flood maps are wrong: the tale of compound hazards

Coastal flooding is expected to increase in frequency due to future sea level rise and more extreme weather, but most coastal flood hazards maps do not portray the increase risk. We dive deeper into how these maps are made and uncover why the current flood hazard maps may be misleading.

Connecting to nature and understanding ecosystem services: the urban perspective

Food and water – two resources vital for life on Earth. These are two prime examples of the products that arise from ecosystem services. There are four broad categories of ecosystem services: provisioning regulating, supporting, and cultural. Food and water are a form of ecosystem service provisioning – these are the products that directly benefit humans. Globalization and climate change are increasingly threatening food and water security, and other vital ecosystem services throughout the world.

Urban Environmental Science – why is it important and what is the big deal?

But let’s think about it. Over 50% of the global population currently resides in cities. Cities are seen as opportunity havens and projections suggest the global population living in cities will surpass 60% by 2050 (UN 2016). That’s a lot of people living on a relatively small area of land. Traditionally, we have created sanitary cities where the objective was to remove waste through engineered infrastructure (think sewers) and move water along controlled waterways (think channelized or buried streams). Nowadays, we are understanding the value of green areas in cities and are moving towards studying the urban environment to improve city design and make it more sustainable.
