Household Adaptation to Climate Change in the Philippines

How do marginalized people living in vulnerable coastal communities adapt to the effects of climate change such as sea level rise? What is an example of this adaptation at the household level? The following article describes one of these interesting adaptations and its implications.

One of the interesting aspects of research is discovering something new. Although a phenomenon has been there for a long time, it becomes a relevant point of interest once its occurrence is viewed more keenly and becomes a subject of discussion.

Take for instance the cross-country research our group conducted last year in the coastal areas of the Philippines, Indonesia, and Vietnam to document the effects of climate change. One of those inquired in the investigation looked into the adaptation of marginalized fisherfolks to the hazards brought about by typhoon/flooding, coastal erosion and saltwater intrusion.

What I found interesting in this climate change study are the unique ways by which marginalized people try to cope up with changes in their environment. In this particular case that we studied, the fisherfolks’ adaptation to the erosive effects of waves in the gradually advancing seawater was investigated.

We visited three communities (locally called barangays) to find out if there are any signs of initiatives to mitigate the effects of sea level rise. There, indeed, are several interesting adaptations made by fishermen in the tropical regions such as the Philippines. I relate one below.

Household Adaptation to Sea Level Rise

Below is a picture of a household adaptation in response to rising sea levels that erodes the thin strip of land a few hundred meters wide. A series of temporary and permanent houses dot this habitable portion that lies between the sea and the concrete highway running along the irregular coastline.

I noticed this ingenious way to keep soil from eroding in the beach of Binduyan, a coastal community lying east of Puerto Princesa in the island of Palawan in the Philippines. It may be a common sight to the uninitiated, but to someone who does research this means a lot.

What were the costs involved?

If you will imagine the time, money (although these materials may have been sourced around) and effort devoted by the person to construct this structure, you will be able to appreciate the significance of this adaptation to the life of the builder. Since we are after economic analysis of household adaptations like this, questions like the following arise in my mind:

  • How many people were involved in constructing the makeshift seawall?
  • How much time did it take them to build such structure?
  • What opportunities did they lose as a consequence of working on the structure (see opportunity cost to understand how important this concept is)?
  • What benefits were gained?
  • Did the benefits justify the cost of construction or was it just a waste of time?

Why would this family go to lengths in constructing this makeshift structure made of local materials? It’s unfortunate nobody was there to ask when we passed through as we walked the beach and note down observations. The owners were out somewhere, probably fishing. But these questions helped us design our questionnaire as this visit was part of our scoping activity.

We measured the height of the whole structure. It is 1.2 meters in height! Did seawater rise that high? How many years did it take to reach that level? What is the distance of the water’s edge at high tide from this house since people living in the area took notice of the rising waters?

Questions Lead to Discovery and Informed Actions

Many questions arise as a result of this simple observation. And these questions will propel you to undertake research focused on your specific concern to contribute to the body of knowledge. That, of course, requires publishing your work for others to learn from. Research findings mean nothing if left unpublished.

You may download and read the results of the study I mentioned above from the WorldFish website. It is titled “Economic Analysis of Climate Change Adaptation Strategies in Selected Coastal Areas in Indonesia, Philippines and Vietnam.” It is hoped that the findings of this research will aid policy makers in coming up with actions to mitigate the effects of climate change thus reduce costly damage to vulnerable coastal communities.

  1. Good day sir Patrick Regoniel! I am very interested in your research paper, my undergraduate thesis is also related to your research paper. By any chance sir, can I ask permission to read your working paper for this topic? It would really be great to read and cite your work sir. Thank you.
