Identifying Climate Change Vulnerable Areas

How to identify critical and vulnerable areas in your village.

This article is taken from our experience in -GIS.

You can read the process here on conducting PRA.

This activity was conducted in five days.

Okay, let’s go now to the basics of risk assessment. In these highly critical days with the changing climate, all we can do is to adapt.

However, doing so needs not just common sense.

We need to have data to support our adaptation and mitigation processes.

Step One:

Conduct an assessment in your village.


You can use Participatory Rapid Appraisal in this case. There are many tools that you can use in this activity and you need to have many participants in order to come up with a solid discussion.

Some of the useful tools in identifying critical areas are:


Hazard map
Hazard Map of Barangay Amampacang

Settlement map,

Protection and tenurial mapping,

Conflict land-use mapping,

Drainage and water use map.

These are just among the maps that you can use to identify critical and vulnerable areas in your village.

 Step two:

Consolidate all the outputs.

To come up with an identified area which is vulnerable to climate change, it is important that you invite different sectors in your village. Just like when working in your PRA. This is done to avoid one-sided and biased discussion.

Don’t worry about consolidating your map outputs, because this is done by overlaying one theme from another.

It’s that simple!

Now, what will you do if you have these maps?

This brings me to the third step.

Proposed your development initiative plan.


In the Barangay where we conduct PRA, the participants proposed to construct creek control and construction of evacuation site.

In the Philippines, not all villages have separate evacuation site.

Conventionally, classrooms, health center, and gymnasium are the best alternative evacuation site.

For them, it is important to construct such infrastructure because they are prone to flooding. And they also planned to make a clean up drive and segregation bin.

In trying to save the environment, we should start from our own little habits.

Remember,  little things matter.

A garbage a day makes your city/town float in rainy days.
