Day_176: Empowering Pacific Island Countries: Innovative Strategies for a Disaster-Resilient Future

 

Let’s learn about disaster risk reduction in Pacific Island Countries.

For Pacific Island countries (PICs), vulnerable to climate change and natural disasters, including tropical cyclones, earthquakes, tsunamis, and volcanic eruptions, disaster risk reduction (DRR) is a crucial part of sustainable development. These occurrences could severely impact the environment, the local economy, and the local communities. It is now more crucial than ever for PICs to concentrate on improving their capacity for disaster risk reduction and resilience.

The concept and practice of disaster risk reduction (DRR) are described by the United Nations Office for Disaster Risk Reduction (UNDRR) as “the concept and practice of reducing disaster risks through systematic efforts to analyze and manage the causal factors of disasters, including through reduced exposure to hazards, lessened vulnerability of people and property, wise management of land and the environment, and improved preparedness for adverse events.” This entails comprehending the particular difficulties that PICs confront in the Pacific region, figuring out the best ways to deal with these difficulties, and cooperating to secure a more resilient future for everyone.

This article discusses how crucial disaster risk reduction is for the Pacific region, looks at essential tactics for improving DRR, look at examples of effective programs, and thinks about how local knowledge and global cooperation may help create a resilient culture. Pacific Island countries may lessen their susceptibility, promote sustainable development, and be better prepared for future calamities by implementing these measures.

Pacific Island countries face distinct challenges that are unique to their region.

Pacific Island countries have many specific difficulties when it comes to reducing the risk of disasters. First and foremost, they are particularly vulnerable to disasters because of their location. PICs are vulnerable to volcanic eruptions, earthquakes, and tsunamis because of their location along the Pacific Ring of Fire. The area is also frequently affected by tropical cyclones, which can result in extensive harm and destruction.

PICs’ low resources and disaster preparedness and response capacity present another critical obstacle. Many of these nations’ inhabitants, infrastructure, and financial resources are modest. As a result, they frequently struggle to create and keep up with the required structures and methods for efficient disaster risk reduction.

Additionally, the effects of climate change are increasing already-existing threats and developing new ones for Pacific Island nations. Natural disasters are becoming more frequent and severe in the area due to rising sea levels, rising temperatures, and altering weather patterns. This makes improving disaster risk reduction in the Pacific much more complex and urgent.

Reducing the risk of disasters in the Pacific region is paramount.

It is impossible to exaggerate the significance of disaster risk reduction in the region of the Pacific. Natural disasters can wreak havoc and create great destruction, affecting the environment, the economy, and communities that persist for years. The Pacific island countries can lessen these effects, save lives, and safeguard their development achievements by investing in disaster risk reduction.

The Pacific region’s Sustainable Development Goals (SDGs) are also strongly related to disaster risk reduction. Natural disasters can directly influence many SDGs, including eradicating poverty, ensuring health and well-being, and fostering sustainable cities and communities. Pacific Island countries may advance toward these objectives and guarantee a more sustainable future for all by improving their capacity for disaster risk reduction.

Finally, reducing the risk of disasters is essential to helping Pacific Island communities become resilient. Communities’ capacity to resist shocks and pressures like disasters, recover from them, and adapt to them is called resilience. By implementing efficient disaster risk reduction initiatives, PICs may empower their communities to increase their resilience and preparedness for future catastrophes.

Discover some highly effective techniques to enhance disaster risk reduction with the following suggestions.

Climate change adaptation

The effects of climate change are one of the biggest obstacles to disaster risk reduction that Pacific Island countries must overcome. As a result, any DRR strategy in the area must include adaptation to climate change as a critical element. Some examples of adaptation methods are enhancing coastal defenses, implementing sustainable land- and water-management practices, and creating climate-resilient agriculture and fisheries.

Climate factors must be incorporated into development planning and decision-making processes as part of climate change adaptation. This can help ensure that investments and development initiatives are created to resist climate change’s effects and not unintentionally raise the risk of disaster.

Infrastructure resilience

Improving infrastructure resiliency is crucial for boosting disaster risk reduction in the Pacific. This entails ensuring that critical infrastructure, such as transportation networks, energy production facilities, and water and sanitation systems, is planned, constructed, and maintained to withstand the effects of natural disasters and climate change.

Developing and enforcing construction rules and standards, using cutting-edge technologies and materials, and integrating risk assessments and management strategies into the planning and design processes for infrastructure are all ways to increase its resilience. Pacific Island countries can lessen the potential harm brought on by disasters and assure the ongoing provision of critical services both during and after disasters by investing in resilient infrastructure.

Early warning systems

Implementing efficient early warning systems is paramount in enhancing disaster risk reduction efforts in the Pacific region. The aforementioned systems can provide precise and prompt data regarding imminent perils, enabling communities and governing bodies to undertake suitable measures to mitigate the consequences of disasters.

Early warning systems encompass a variety of technologies and methodologies, including but not limited to satellite-based monitoring, seismometers, and community-based observation networks. Apart from the development and execution of stated systems, it is crucial to guarantee that communities possess the ability and knowledge to understand and respond to early warning information.

Community engagement and Preparedness

Any practical disaster risk reduction approach must include community involvement and preparedness. Pacific Island countries may ensure that local needs and views are considered and that communities have a greater capacity to respond to and recover from disasters by involving communities in designing, implementing, and monitoring DRR programs.

Creating community early warning systems and carrying out of regular disaster exercises are examples of community-based disaster preparedness initiatives. Additionally, community participation can increase the efficacy and support for DRR activities by fostering trust between citizens and authorities.

Case studies of successful disaster risk reduction initiatives

The successful implementation of various disaster risk reduction efforts in Pacific Island countries has shed light on practical methods for strengthening DRR in the area. The Pacific Catastrophe Risk Assessment and finance project (PCRAFI), which emerged in response to the expanding demand for disaster risk finance in the Pacific, is one such project.

Participating countries have access to catastrophe risk models, financial safety nets, and technical assistance for disaster risk management through PCRAFI. With the tools and resources it offers, the project has proven to be a highly successful means of assisting Pacific Island countries to identify better and manage their disaster risk.

The Pacific Climate Change and Migration (PCCM) project, which intends to raise the resilience of vulnerable populations in Fiji and Tuvalu to the effects of climate change, including displacement and migration, is another effective program. The project has concentrated on a variety of interventions, such as the building of climate-resilient infrastructure, the promotion of community-based disaster risk reduction, and the development of sustainable methods for livelihood.

The PCCM project highlights the value of tackling the underlying factors that increase disaster risk, such as climate change and incorporating disaster risk reduction (DRR) into larger development projects. Pacific Island countries may create more resilient and sustainable populations by approaching disaster risk reduction strategically.

The Role of international cooperation in disaster risk reduction

Effective disaster risk reduction in the Pacific region requires global cooperation. International cooperation and support are crucial because many Pacific Island countries lack the resources and capacity to manage their disaster risk independently.

International cooperation can take many forms, including knowledge sharing, capacity building, and financial and technical support. For instance, the United Nations Development Programme (UNDP) has generously supported initiatives in the Pacific to reduce disaster risk, such as creating early warning systems, establishing community-based disaster preparedness programs, and promoting climate change adaptation.

Incorporating regional expertise and customs into DRR activities can be significantly aided by international cooperation. International partners can contribute to ensuring that DRR strategies are practical and culturally appropriate by collaborating closely with local communities and traditional leaders.

Incorporating local knowledge and traditional practices

Initiatives for reducing the risk of disaster must incorporate local expertise and customs to be effective and long-lasting. The inhabitants of the Pacific Islands have abundant knowledge and experience in dealing with natural disasters, and their customs and traditions can offer essential insights into efficient DRR techniques.

Many Pacific Island societies, for instance, have created complex early warning systems using their understanding of the environment and natural occurrences. Countries in the Pacific Islands can improve their capacity for disaster preparedness and response by integrating these systems into more comprehensive DRR policies.

Culturing climate-resilient crops and constructing cyclone-resistant homes are examples of traditional practices that can offer important insights into effective adaptation strategies. Pacific Islander countries may create more resilient and sustainable communities by recognizing and adopting these practices into DRR projects.

Building a Culture of Resilience in Pacific Island Communities

Effective disaster risk reduction in Pacific Island communities depends on fostering a culture of resilience. This entails implementing efficient DRR measures and giving communities the tools they need to manage their risk of disasters and increase their resilience.

Communities can be empowered to actively participate in disaster preparedness and response through community-based approaches to disaster risk reduction, such as those used in the PCCM project. These techniques can also assist in fostering trust and collaboration between communities and authorities.

Furthermore, building a culture of resilience in Pacific Island communities can be facilitated by raising awareness and educating people about disaster risk reduction. Pacific Island countries may create more resilient communities and lessen the potential effect of natural disasters by giving populations the expertise and skills they need to understand and handle their disaster risk.

Monitoring and evaluating disaster risk reduction progress

Monitoring and assessing their progress is crucial for disaster risk reduction strategies to be effective and persistent. Pacific Island countries can continuously hone and enhance their DRR strategies, enhancing their capacity for resilience over time by monitoring progress and identifying areas for improvement.

The development of data management systems, setting up surveys and evaluations, and establishing performance indicators are just a few examples of the various ways that monitoring and evaluation can be carried out. Pacific Island governments may ensure that their DRR projects are based on evidence and successful by investing in these tools and procedures.

Envisioning a Robust and Sustainable Future for Pacific Island Nations through Collaborative Endeavors and Holistic Strategies

It takes a variety of tactics and approaches to effectively increase disaster risk reduction in Pacific Island countries. Pacific Island countries may build a more robust future for all people by emphasizing infrastructure resilience, early warning systems, community participation and preparedness, and incorporating indigenous knowledge and traditional practices.

Effective disaster risk reduction in the Pacific requires global cooperation and encouraging a resilient culture. Pacific Island nations can lessen their susceptibility to natural disasters and promote sustainable development by cooperating and strengthening local populations.

Monitoring and evaluation will be crucial to ensure that DRR projects in the area are successful and long-lasting. By continuously enhancing and upgrading our methods, we can create a more resilient and prosperous future for Pacific Island nations and their populations.

Day_172 : Hollywood Movie “The Beach” and The 2004 Indian Ocean Tsunami in Thailand

Past writings are to be disclosed little by little with some changes.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>

The Supreme Court of Thailand ordered 20th Century Fox Inc. and its local subsidiaries to restore the ecosystem of Phi Phi Island, acknowledging that the company degraded the environment around Phi Phi Lei Island for the filming of the Hollywood movie “The Beach” in 2000 on December 7, 2006. The film, starring Leonardo DiCaprio, has made great strides in the development of tourism on the island and displaced many tourists, but the island was one of the worst affected areas by the Indian Ocean Tsunami of late 2004, and many tourists lost their lives.

Flyer: The Movie “Tha Beach”

Tourism development for economic development and environmental issues lay largely in the background of why Koh Phi Phi was one of the hardest-hit areas by the tsunami in Thailand.

It all started with the baht crisis that hit the Thai economy in 1997. In the early 1990s, the Thai government established the Ministry of Science, Technology and Environment and the Environmental Fund, enacted a number of environmental laws and enacted a national environmental boom, which began in the early 1990s. A prime example is a controversy over the alteration of the environment for Hollywood movies, known as “the beach controversy,” which began in 1998.

This was sparked by an attempt by a film crew to alter the landscape of Maya Beach on the island of Phi Phi Ley. For the filming of football game scenes, the sandy beach was widened by bulldozers and non-indigenous coco palm trees were imported and planted on the beach to create an image of a tropical paradise. The Royal Forest Department’s decision to approve the alteration was a measure that went so far as to bend the law in order to attract international investment with the aim of reviving the Thai economy.

This has led to the neglect of nature conservation, and local NGOs and others have begun to investigate and prosecute the environmental degradation around the island.

The tsunami that struck Phi Phi Island on December 26, 2004, occurred in the midst of such tourism development.

Now, two years after the tsunami, the island of Phi Phi Lei and the surrounding areas have regained their natural beauty, having been cleared of the man-made nature created by the tsunami.

Mr. Songboon of TOT Krabi Province, a major telecommunications company in Thailand, said, “I’ve been watching Phi Phi Island for a long time, but the sea was the dirtiest just before the tsunami. He said with great emotion, “The beaches around the area after the tsunami have regained the beauty of 10 years ago. He is currently staying on Phi Phi don Island to set up an internet connection.

Picture: Maya Beach

Mr. Spar, who runs a dive shop in the hard-hit Thongsai Bay, said, “For a while after the tsunami, we were in a vicious circle, with fewer customers and higher rates for the limited accommodations available to stay, and even fewer customers. However, now the sea itself is getting very clean and the city has recovered a lot, and the customers have returned. Management is getting a little better, too. and a glimpse of hope.

Picture: Thongsai Bay

Supreme Court decision that seems too little too late. It will be interesting to see how Phi Phi Island rebuilds and learn from the experience of the tsunami and its recovery process.

Day_171 : Past Interview Records – PTWC (Pacific Tsunami Warning Center) in Hawaii (2)

Interview Records at PTWC No.2
2008.2.26 (Tue.) at 1000 am

The records from the interview survey are shown below.

■ Science and technology
Many models of the tsunami have been developed. However, it is difficult to adopt because it is crucial whether it is practical or not.

■ Staff training
Only internal training is available.

■ A system where Civil Defense gives warnings to citizens.
There is a hotline to the provincial government and another one to the federal government.

■ Work shift
One person is always at the center for 24 hours.
8hr-4hr-4hr 4hr 16hrs are in shift
When there is a problem, three staff gather at the center.

■ Backup
The center’s backup is at the Alaska center and if Hawaii doesn’t work. Alaska center can cover.

■ Relationship with media
Concerning the media, media is, in a sense, a partner.
Civil Defense needs 3 hours before the event to evacuate. for that reason, there are too many time constraints. The media is fast. However, there are various restrictions. To decide to proceed with the warning or not, the media has no such authority. Also, in the United States, the media is a business and not state-owned, so it could mislead. You must always pay attention to the points.

■ Resources
Before the tsunami damage of 2004, the conditions were very limited in resources. A lot of money was invested in this field since the events of the year. The function of the center has been improved because of that. The staff has increased. The 2004 event was a severe tsunami disaster by letting the world know the reality.

Day_168 : Past Interview Records – PTWC (Pacific Tsunami Warning Center) in Hawaii (1)

Continue to the past New Orleans Interview Records, I would like to open the memo about the interview to PTWC. It was a great time and I learned a lot from the interviews.  So I would like to share the fact to let you know their works to tackle the tsunami disasters in the world.

PTWC is the core center for the tsunami warning well known to the world.

2008.2.26 (Tue.) at 1000 am
15 staff, director, deputy director
Information Technician, including nine scientists
16-hour shift on 8-4-4, homes are next to the center

The records from the interview survey are shown below.

■ Evacuation
There is no international standard in terminology. Terminology varies by country/region. The words sometimes make me confused. Also, in the past, it was two either evacuation nor no evacuation.

■ Warning Error
It is challenging to give a warning. There are errors in the original earthquake and the tide data. There is an error in the gauge also.
To judge them collect is too hard. So, it can be said that 99.99% is an error.

In Hawaii, only a quarter of evacuation was actually damaged in the past. It is not unusual that although there were evacuations, there were no damages at all.

■ Past data and warning judgment
Only use a few. Because how to put out the past data, equipment, etc.are hard to do. Which way is the numerical model used to determine if the earthquake becomes a tsunami is complicated. There are more things to do.

■ Relationship with other countries
The countries that are most focused on warning about tsunami in the Pacific are Japan, America, Australia, Chile, Canada, and Russia. Also, it is not possible to evaluate the inspection records of other countries. This should be noted.

■ At the time of the 2004 tsunami
Most of the records before the Indian Ocean Tsunami were reported hourly, so judge the event was tough. Every 15 minutes, now every 6 minutes is normal and very good.

■ Conditions for cancellation
Make a comprehensive decision. The problem of reflections adds to the complexity. Not only direct waves but also an indirect wave should be considered.

Day_157: Disaster Warning (1)

I will update a column of the NIED e-mail magazine which I wrote a long time ago because the content is not faded with time. (I will do this step by step in Japanese and English) I will also add comments to update the situation.

Sorry, now I am revising this post because of the difficulties of the translation. This post will be revised again. Thank you.

Published May 6, 2010
NIED-DIL e-mail magazine: Disaster Warning (1)

■ Disaster Warning (1) ■

In February 2008, a survey provided an opportunity to visit the Pacific Tsunami Warning Center (PTWC) in Hawaii. In a study, I interviewed the director of the PTWC, and the first thing that caught my attention was the role of the media. The director told me that a public tsunami evacuation alert required three hours before the event, which was too time-sensitive, but the media was an advantage to do this. However, for the government organization, there were various restrictions, such as warnings in an international framework. I remembered the Chilean Navy’s disaster response to the damage caused by the earthquake and tsunami in Chile in February this year.

Next, I was interested in science, technology, and data that are the basis of the alarm decision. I think that normal (flood etc.) warnings will be judged based on current and past data, but especially for tsunami warnings, there were errors in the data of the original earthquake and the tide gauge. To do judge, we should know the 99.99 percent could be the error. The fact that the past data is not very useful because the devices to figure out the data are changing day by day, making it difficult to rely on it.

From these facts, it was generally noticed that the disaster warning was based on the combination of the progress of science, technology and the competence of the person in charge. The actual warning also relies on the institution belonging to it. For example, it was also needed to add variables such as the recipient of the alert, the psychology of the local people, social situation, and various systems.

Day_133 : Science, Technology, Population, and Lessons for DRR

Japanese people have tended to trust the government and science & technology so much.
These are one of what we learned from recent disasters. After the second world war, Japanese gov. has built high sea walls along the coastline especially potential risk areas all over Japan. We have also developed warning systems along with rapid economic growth. Not only those, but we have also developed soft countermeasures such as disaster education and training, especially after the 1995 Kobe Earthquake. After the Great East Japan Earthquake and Tsunami (GEJET) disaster, we have realized what has happened because of our over trust to the government and science&technology. This is why Japanese gov. has particularly focused on the community since the disaster, establishing a new frame on the community disaster planning in the disaster countermeasure basic act. The recovery plans on the affected coastal communities tended to change more integrated manners and so did disaster countermeasures than before, looks like turning back to the time when we did not have advanced science and technologies.

We need to know the limitations of the gov. and science&technology’s roles. We also can consider the demographic change to do the job for disaster risk reductions. For example, Japan is facing a severe aging society, so our government resources will be decreasing to cover the situations. We need to have more self-help and mutual help than public help.

Learning from the lessons and past wisdom with those considerations is also very important. “Inamura no Hi” is one of the important lessons we can learn from the past.

Day_88 : Inamura no Hi

“Inamura no Hi” is a story of a man who noticed a precursor of a large tsunami at the earliest stage and led village inhabitants to a higher ground by burning harvested rice sheaves. This story was based on a true story at the time of Ansei-Nankai Tsunami (1854), which claimed around 3,000 lives in the coastal areas of Western Japan (ADRC).

Hirokawa Town’s video well explains the background of the story in short and their tsunami disaster education.

 

 

 

Day_105 : Relocations or Rebuildings (2)

 

Day_94 : Relocations or Rebuildings (1) (Tentative)

After the 1896 Meiji sanriku tsunami, many communities considered relocating to higher grounds, however, a few communities could proceed the relocations. The main reasons why they could not relocate to higher grounds are the followings (Nakasu et al., 2011):

1) It was very inconvenient for them to settle the areas which were far from the sea because they were mainly fishermen or living their daily lives by the sea.

2) Most of them were doing small size fishing related businesses, had not enough budgets to relocate.

3) There were difficulties to attain the agreements to do relocations among the community members.

4) They, community members, had conflicts with land owners to select and purchase the relocation lands.

5) There were technical limitations to create a land for living on the slope because Japan did not have enough technological level at that time.

They mainly relocated to higher grounds by their own decisions. However, some groups gave pressures on the people who had planned to move and tried to let them give up to do so because they would like to maintain the communities to recover.

A small number of the communities moved to higher grounds, however, some went back to their original places. In addition, their relatives or other village people started to live there. Some families positively accepted the immigrants from outsides to maintain their ownerships.

Finally, almost all communities had chosen to rebuild at the same places, so the risks were retained and this combined with the fact that they were re-affected by the 1933 Showa sanriku tsunami disaster.

Concerning after the 1933 Showa sanriku tsunami, this will be explained later.

Day_101 : Deth toll tells

The following Figure 1 is the death toll by country after the 2004 Indian Ocean Tsunami disaster.

death toll
Figure 1 Death toll by country

Then Table 1 indicates the death toll flow of each country.
What can we say about this?

Table 1 The Death Toll Flow
Death Flow

As you can see Table 1, the number of victims (deaths) is changing day by day. For instance, the number of deaths reported in Indonesia from 05.01.15 to 05.01.30 is decreasing. The death toll flow of Somaria looks somehow strange. If we can consider these kinds of views, we can understand that the reported death numbers reflect the social situations of the country. These views will be discussed later.

Next, Figure 2 shows the picture taken at the tsunami memorial meeting in Phang Nga province one year after the disaster. This definitely indicates so many foreigners were killed by the tsunami. Figure 3 support this fact. This is because the affected areas were sightseeing spots. Even Thai victims include so many visitors from all over the country.

Day_98 : The Major Tsunami disasters in Sanriku Ria Coast in Japan

The following slide indicates the Great East Japan Earthquake and Tsunami(GEJET)disaster’s data by each municipality (IRDR conference).You can see the fact that Sanriku ria coast has more severe damage compared to the population of the municipalities.We also need to notice the Sanriku ria coast has a long history of tsunami disasters.But why did they have a sever damage again?

sanriku tsunami history death
Figure 1 Tsunami Disaster Impact in the Sanriku Ria coast (IRDR)

The Sanriku areas have a special geographical condition mentioned as Sanriku ria coast. The coast has mountains close to the sea, so residential areas are limited only in the distributed, narrow and lower zones near to the sea and the areas become very vulnerable against the tsunamis. The bays in the coast are small and the sea inside the bays are very deep. This makes tsunami faster and higher, this is why the Sanriku ria coast makes the one of the highest tsunami risk areas in the world.

Because of these characteristics, the communities in Sanriku ria coast, mainly in Iwate prefecture historically has been severely affected by tsunami disasters such as Meiji Sanriku earthquake tsunami (Meiji (1896)), Sowa Sanriku earthquake tsunami (Sowa (1933)), and Chilean earthquake tsunami (Chilean (1960)) disasters compared to the flat coast mainly in Miyagi prefecture and other areas in Japan.

See the below “Relocation or Rebuilding (1)”

The following is the brief explanations of each tsunami disaster. The Figure 2 (Figure 1 of the Day_94 post) does not include the Chilean Tsunami.

sanriku tsunami history

 The Tsunami Disasters in Tohoku (Cabinet office of Japan)

1) Meiji sanriku tsunami disaster(1896), this disaster is so called a surprise attack tsunami disaster happened at approx. 7:30 pm, 15th of June in 1896 mainly in Sanriku ria coast. The dead and missing number has reported over 22,000. The earthquake is not so strong (Japanese earthquake scale indicates Shindo 1-2), however, tsunami is very strong and high (max. height is 38.2m at Ayasato area (present Ofunato city) compared to the earthquake movement scale. The first wave arrival is approx.35m after the earthquake. The Meiji sanriku tsunami disaster (1896) is the worst tsunami disaster ever in Japan.

2) Showa sanriku tsunami disaster(1933), this tsunami disaster can be examined the lessons learned from Meiji (1933) mitigate the impacts. This tsunami attacked mainly the Sanriku ria coast at approx. 2:30 am, 3rd of March in 1933. Even if the midnight, the residents evacuated so quickly because of their memories of the Meiji (1896) with strong earthquake (Japanese scale is Shindo 5.5). The max. tsunami height is 23m at the same place, Ayasato area, with Meiji (1896). The first wave arrival is approx.30 min. after the earthquake.

3) Chilean tsunami disaster(1960), this is caused by the tsunami generated offshore in the long distance. This is coming from Chile in South America. The earthquake occurred in Chile was magnitude 9.5 and this huge earthquake generates tsunami and reach to Japan after 22 hrs and a half. The tsunami come approx. at 3 am, 23rd of March in 1960. The death number is 139 all over the Japan and Sanriku ria coast is the worst such as 63 in Ofunato, 37 in Shizugawa (present Minamisanriku), and 8 in Rikuzentakata.

4) Great East Japan Earthquake and Tsunami(GEJET) disaster(2011), this disaster is the deadliest disaster after the Second World War in Japan. The earthquake happened at 2:46 pm, 11st of March in 2011. The total casualty number is 19,846 based on the EM-DAT.The max.tsunami height is 40m at the Sanriku ria coast. The first wave arrival is approx. 30 min. after the earthquake.
