Joppe began his presentation with a discussion about polders, using a map of the Netherlands to assist in his explanation. Coincidentally, the opening image to chapter 4 of the Delta Urbanism’s is the same map of the Netherlands. However, Joppe compares a map of the Netherlands in the year 1300, with a map of it in current times. As shown in the screenshot attached to this post, the two red circles on the maps identify the areas of most significant change due to polders. The picture from the delta urbanism’s piece gives a look at the Netherlands in the present, and helps further give detail to how different hundreds of years of polder-usage made the Netherlands appear. I decided to attach a third picture to my post, another from Joppe’s first video. This image depicts the lands relative height compared to sea level. Most of the areas where polders terraformed the land are below sea level, further showing how much land was reclaimed. Joppe also goes on to mention that originally the development of the polders was for farming, because the city centers didn’t have the space. When looking at the map from the delta urbanism’s piece, you can see that many of the areas which became polders still appear relativity undeveloped.
