In our video, we'll take another look at climate change.
Another look, since we have already mentioned this issue.
We'll talk about how this issue can be planned.
We'll take a certain number of items
that we have mentioned previously.
Climate change summons up two words:
adapting and mitigating.
Either we adapt to the changes:
the higher the sea level, the more we'll factor it in in our buildings.
Or we mitigate, which means we'll fight against
the effects of climate change.
So, either I adapt to rising sea levels,
or I prevent sea levels from rising more.
Then, from the perspective of populations,
there is a capacity for people to adapt,
but also from the perspective of governments
there are financial, social capacities to adapt to climate change.
At the other end of the spectrum is vulnerability, being unable to adapt.
These are the four elements to keep in mind
when discussing climate change and urban planning.
What are the effects?
Let's take an example:
there are the effect itself, the problem it poses,
and the the measures at our disposal in terms of urban planning.
Example: rising temperatures.
The problem are the heat spots, everywhere in the city.
the measures to be considered are planting trees,
the shaping of public spaces, air currents in the streets, parks.
Another example: the rising number of insects
as a result of rising temperatures.
These are issues that are not well-known yet
but that will be more widespread.
What is there to do?
We can fight against insects, with chemicals,
but there is also the option to drain certain wetlands.
Mitigating the effect of the change,
in terms of urban planning,
means to make some important decisions.
We mentioned compact cities
that are less energy-consuming than spread-out cities,
with all the caveats I mentioned
and the several other factors that need to be monitored,
but let's say that compact cities
would produce less green house gas
and, as a result, urban planning
is a way to mitigate.
On the other side, the problem of heat spots
is a direct consequence of the effect of climate change.
There is not much to be done apart from adapting
with a series of measures in terms of urban planning.
