What is sustainable development?

The linkages between the sustainable development goals impact on the solutions. The more points you get for the project, the more sustainable. Synergies Vs tradeoff. Potential projects that can be submitted for sustainability.

What are planetary boundaries?

I like the workshop in the it allowed me to see sustainability not only for the environment but also the society and the economy.

Coastal GI 2022

Using Google Earth to compare the changes of ECP between 2010 and 2021

The following pictures and videos were taken during the fieldwork on 2 July 2022.

Explore the 360 video below.

Students crafted the hypotheses for geographical investigation.

Students were given the tide level table and weather forecast, prompting them why these are necessary.

Students recorded the data collected on the worksheet. At station B, they also input the weather data, wave frequency and longshore drift data onto a Google form in which the results are collected for group analysis.

Using Google Earth and image slider

Using Google Earth, you can easily access the satellite image of the area in the past. Just click on the year which appears on the left bottom corner and it will bring up a time slider in the top left. Select the time period you want and screenshot the image. Examples are screenshot for ECP.

ECP 2010

ECP 2021

Using https://juxtapose.knightlab.com/ you can generate the image slider for easy comparison of the 2 images. You can embed it with the html code generated like below. Or just copy the link and give to the students

Students can easily compare the 2 images. How effective is the breakwaters in protecting the East Coast? You can see that there the beach has grown bigger, probably due to the greater amount of beach deposit.

A great way to compare the images in terms of spatial and temporal scales.

Google Earth for Coastal Studies

Gotten the students to explore the South coast of England (Seaton ) using Google Earth. I have place marked 7 sites for them to study the coastal features and processes.

You can access the Google Earth file here - https://tinyurl.com/GEcoastmap

Using the ruler function, they could measure the length and width of the spit. They could also infer the direction of the longshore drift using the north arrow and observing how the spit has extended from the land towards the sea across the river mouth.

The ability to conduct virtual fieldwork without being there physically.

Google Earth also allowed authentic learning as they make comparison of the scale in the real world and make observations using virtual reality.

Pleasantly surprised this time round to see two students screenshot and annotate on them what I highlighted on the coastal features using Google Earth. Students are motivated to apply their learning and make observations from the Google Earth real life images.
