00:00What is your dream house?

00:03A sleek modern house?

00:05A bungalow?

00:07A big mansion?

00:09Or a cozy house?

00:11Where do you plan to build it?

00:14On a paradise-like beach?

00:16In the mountains?

00:18Or by the lake?

00:20During a climate crisis, is your dream house ready?

00:24Faced with the reality of strong storms?

00:30What is your dream house?

00:39Due to the heavy rainfall caused by Hurricane Christine in October 2024,

00:44it caused landslides in the towns of Talisay, Laurel, and Agoncillo in the province of Batangas.

00:54One of the most affected is the town of Laurel.

00:58Landslides caused landslides, landslides, and landslides

01:03caused landslides, landslides, and landslides

01:06In December of last year, the storm still hit the area.

01:14It's like a diluvium.

01:16It's all water, there's nothing we can do.

01:19We can't even climb a tree.

01:22It's too high.

01:25It's a disaster.

01:27The water runs fast.

01:30There are a lot of vehicles, cars, trucks, and tricycles.

01:35I carried all of them.

01:37I carried them in a pailo.

01:39I was 54 years old when this happened.

01:43I didn't expect it to be this big.

01:47Because of the rapid rise in the water level, they were unable to escape.

01:52We couldn't climb a tree.

01:54We had to carry all of them.

01:56We were in a pail for 3-4 hours.

01:58The children were crying.

02:00They were praying.

02:02They were all crying.

02:06After the flood, the landslides hit the town of Laurel and Agoncillo.

02:12If the landslides didn't happen, we would have drowned.

02:17We would have been carried away.

02:19Thank God, the landslides stopped.

02:21The landslides helped the water level rise.

02:25Now, there are trees, trees, and palm trees.

02:30There are a lot of palm trees.

02:33If the landslides didn't happen, we would have been carried away.

02:38Because the water level is high in the river,

02:42that's why the landslides happened.

02:46Just like how the river was flooded,

02:48Dennis' house was destroyed.

02:50When the flood came, the landslides came.

02:54I broke the windows.

02:58I broke the windows.

03:00The windows were broken.

03:02The water level was this high.

03:05Up to here.

03:11Our house was destroyed.

03:15Our store was destroyed.

03:19My wife's house was flooded.

03:24Here, we walked to the window.

03:32This window was broken.

03:35So we could escape from the flood.

03:38Here, this is a washout.

03:41This is a mess.

03:44This is a mess.

03:47This is a mess.

03:49And this is a mess.

03:51I have two children.

03:53This is a mess.

03:55It's not fixed yet.

03:59It's a mess.

04:01This is where the water came in.

04:03At the end.

04:06Aside from the flooded end of the river,

04:08it also left more than two acres of land.

04:17Before, half of the land was made of stones,

04:20the other half of the land was made of plywood.

04:22Everything was destroyed.

04:24Everything was destroyed.

04:26We lost everything.

04:30We lost everything.

04:32We lost everything.

04:36The location, location, location is a hot topic

04:39whenever we talk about real estate.

04:41In times of climate crisis,

04:43what other factors should be considered

04:45before you can say that a place is safe?

04:53Here at Project NOAA of the University of the Philippines,

04:56MAPA is their platform.

04:58On their website,

05:00you can see if a place is dangerous.

05:03Know your neighborhood.

05:04Not only your house,

05:06but also your junior's school,

05:08your father's office.

05:10You can see it.

05:11So that when a disaster happens,

05:13we know what to do.

05:15We know if the house, office, or school will be hit.

05:19And most of all,

05:21where we will go.

05:23Because these maps

05:25not only show where the most dangerous place is,

05:29they also show the places

05:31that can be visited that are the safest.

05:35If there is a bad weather,

05:37these are the things that can happen.

05:39There can be floods.

05:41You can see the branches

05:45that stick to bigger rivers

05:48until they reach the sea or the ocean.

05:51There can also be landslides.

05:54And if the wind is strong,

05:56there can be a storm surge.

05:58Those are the red ones.

05:59So those places

06:02are called dangerous places.

06:05If there is a bad weather,

06:07and we know that our house, school, or office

06:11is in a dangerous place,

06:13we should flee.

06:16But where should we flee?

06:18To those white places.

06:19So that it won't be hard,

06:20look for the white places that are the safest,

06:24the closest to your house

06:27or school.

06:29So that you won't have a hard time.

06:31You don't need to move

06:34to the other province.

06:36Just stay in the same barangay.

06:39You can see your house up close

06:42and the dangers that surround it.

06:45As you can see, it's high-resolution.

06:47This technology is called

06:49Light Detection and Ranging.

06:51To show you the landscape

06:53of a high-resolution barangay level,

06:55where the dangers are,

06:57and where the safest place is.

07:00That is very important.

07:03The safest place.

07:05Because you have a higher chance of survival.

07:09Project NOAA was established

07:11on Nationwide Operational Assessment of Hazard in 2012.

07:14After the earthquake in Mindanao.

07:17The government wanted

07:19to have a responsive program

07:22for disaster risk reduction.

07:24It was led by the Department of Science and Technology.

07:27And it was taken by researchers.

07:31Researchers who do research

07:35on disaster risk reduction

07:37and new methods.

07:40Lessons from past disasters.

07:43The program was suspended in 2017

07:46due to the government's lack of funds.

07:49But it was continued

07:51by the University of the Philippines

07:53because they saw the potential to save

07:55millions of Filipinos

07:57from the floodwaters.

07:59Updating information does not stop.

08:02Mapping does not stop.

08:06Because our land changes.

08:09Conditions change,

08:11especially when there is climate change.

08:14When there is climate change,

08:15the former small floods

08:17will become larger floods.

08:19And not just sometimes,

08:21if not immediately.

08:26This is a map of Laurels.

08:28In Batangas.

08:30And this is the community.

08:32The parish church is there.

08:35The municipality is here.

08:37And this is the community

08:40where there are many houses.

08:42If you live there,

08:44and there is a possibility of flooding

08:46and landslides,

08:48check the flood landslide

08:51and storm surge.

08:53It's good because you can see

08:56the dangerous places

08:58and the not-so-dangerous places.

09:01If you are only there temporarily,

09:05not just for a week or a day,

09:09if the weather is bad,

09:10you can move from here.

09:12Because those are the safest places

09:15in the community.

09:20This is the town of Agoncillo,

09:22next to the town of Laurels in Batangas,

09:24which was also flooded by the community

09:26because of the flash floods

09:27caused by the heavy rain

09:29caused by the storm Christine.

09:31It also raised the water level in Taal Lake.

09:36Because of this,

09:37it's game over for the houses

09:39that were completely flooded.

09:49These are the four houses

09:50that were abandoned

09:51because of the storm Christine.

09:53This is where I live,

09:54at the end of the house.

09:57Suddenly, the flood came

09:59and the landslide happened.

10:02Elena's dream house

10:03is this house next to the landslide.

10:06It was beautiful before.

10:07It was really beautiful.

10:09Because the plan here

10:10is to build a baywalk

10:12that is attractive to tourists

10:14and next to the landslide.

10:16The seashore was far away

10:18from where my house was built.

10:22In 2018,

10:23the seashore was 50 meters away

10:25from where their house was built

10:27until it was gradually reclaimed by nature.

10:47We spent almost P350,000 in 2018

10:50to build this three-story house.

10:55The rooftop will be made

10:58to make it attractive to Taal

11:01and to continue the baywalk.

11:03But this is what happened.

11:05The storm Christine.

11:08Their house is still submerged in water

11:10and it's dangerous to live here.

11:13First of all,

11:14if you're going to buy a house,

11:16check if the house is in the house.

11:19It might be dry now

11:20because there's no bad weather.

11:22But if it rains,

11:23if there's a storm,

11:24it might sink to the second floor.

11:37This house in Montinupa City

11:39is an elevated design.

11:41The house is built on stilts

11:43and has a bay underneath.

11:45In the map of Project NOAA,

11:47you can see a house near a danger zone.

11:50A tree near the house

11:52that might erupt.

11:55This house was designed

11:57by architect Alistair Sadi.

11:59His inspiration is a modern house.

12:03The main feature of this house

12:06is the bay.

12:07That's why it's on stilts.

12:09The bay design is not native.

12:14It's a rat guard

12:16to prevent viruses and pests

12:19from entering the main house.

12:21It's resilient from flooding

12:22because it's already elevated.

12:24It's floodproof.

12:25We recommend stilt houses

12:28for flood-prone areas

12:31near rivers and creeks

12:33where it can overflow

12:35and reach your location.

12:38You can also buy roofs

12:40with the right angle.

12:41The roof design here

12:43is oriented in a way

12:45that it's not against the strong wind

12:50so that it won't uplift

12:53when there's a typhoon.

12:56Trees and plants are not just a motif.

12:59Their placement is also strategic.

13:02The presence of plants and trees

13:04hold the roots of the soil

13:08so that the elevation of our lot

13:11won't change.

13:16This house is called a cuboid.

13:18It can withstand typhoons,

13:20strong winds,

13:21and hot weather.

13:24The designer and innovator,

13:26Hilvian,

13:27says the typhoon

13:29in Bicol has increased.

13:31When I was young,

13:32I experienced typhoons.

13:34But not like now.

13:36Typhoons are stronger now.

13:37The old houses

13:39have long eaves.

13:41Sometimes, you can use the eaves

13:43of the old houses.

13:45When the wind hits the eaves,

13:48it pushes the eaves up.

13:50The tendency of the wind

13:52is to push the eaves up.

13:54The first thing that can be damaged

13:56is the gutter.

13:58When the gutter is backlash,

14:00the typhoon will come directly.

14:04I created an aerodynamic form.

14:07When the wind hits the eaves,

14:09there's no stress.

14:12I made a simulation.

14:15The flat surface

14:17shows how the wind hits the eaves.

14:20There's a lot of stress.

14:22But when I removed it,

14:24the wind will go inside.

14:26The shape is the same.

14:30No matter where the wind comes from,

14:32it's safe.

14:33If you notice,

14:35the usual house

14:36has a high ceiling.

14:39It's too high.

14:41Since I removed the aerodynamic form,

14:45I can't make it higher.

14:48So, it's like this.

14:50That's how it started.

14:52It's kind of plastic.

14:54But in this construction,

14:56I want to show it like this.

14:58Instead of making it higher,

15:01I lowered it here.

15:05In 2020,

15:06he started to build a decennial cuboid house.

15:09In 2022,

15:10he built two prototypes in Bicol.

15:13The design is patented.

15:15Some countries are interested in building it.

15:18This is optional.

15:19It's for hot areas.

15:22This can be raised.

15:25The air will come out here.

15:28But it depends.

15:29If the rain is too heavy,

15:32we can adjust it.

15:34The material we use

15:36is APS,

15:37Expanded Polystyrene.

15:39This is not the usual CHB concrete.

15:44Even at 7 p.m.,

15:46it's still hot when you touch it.

15:48This one,

15:49even if you touch it directly,

15:51when you touch it inside,

15:53it's cold.

15:55A house is worth 1.2 million pesos.

15:59This is suitable for high areas

16:01except for low areas.

16:03It's not designed for flooded areas.

16:06If we can give it a chance,

16:08funding from the government,

16:10and people who really need it,

16:15I'll be happy.

16:19A new strategy is not enough

16:21to save us from the climate crisis.

16:24More importantly,

16:25the government's responsibility

16:27is to build communities for the people.

16:30We should be designing homes for the future.

16:32And we should be building communities

16:34that will last.

16:35If you look at it,

16:37it's the same for local government units

16:40when planning the zoning of their area.

16:43Where will the critical facilities be built?

16:47Where will the hospital be built?

16:49Where will the future developments be built?

16:52Where should the seat of government be placed

16:54for the people in that area to avoid flooding?

16:58So that when development is avoided,

17:01hazards are avoided,

17:02or floods are avoided,

17:04we won't have a disaster

17:06even if floods occur.
