5. Lava Bombs                                               6. Lava Flow

What effects do you think these hazards have?

Which cause the most deaths / damage to landscape / damage to property?

Which is the worst case scenario?


Mount Patana

Mount Patana has been dormant for many years now - but has started to erupt!

Radio messages have been released........

1. Can you decide which hazard is being reported?

Study the map below


2. Which settlements will each hazard effect?

3. Mark the hazard areas onto the map and label them.

4. Add annotation to describe the hazard and their effects.
A. Primary Effects - immediate consequences
B. Secondary Effects - effects caused by the primary impacts
i.social - on the people
ii. economic - effecting money, trade and business

Koh Phi Phi Koh Finished?

Will Koh Phi Phi Be 'Koh' Finished Soon?

If studying tourism, please have a look at my i-book 'Tourism A Unit of Work for KS3, GCSE & IGSCE' by Alison Potter


Article by Bella Papadopoulou Dobrowolska

Thailand has become the most popular tourist destination in South East Asia. The fact that this country has to offer everything from beautiful white sandy beaches in the South to trekking among the hill tribes in the North. The increasing ease and inexpensive price of traveling to and within Thailand, has led also to a major increase in the number of tourists flocking to this Southeast Asian nation annually. But at the same time that the economy is expanding, the environment is taking a strong hit. Unfortunately the negative environmental, cultural, and biological impact of tourism in Thailand is increasing, and the government has been fairly passive in dealing with the various related problems.


Koh Phi Phi 2013

So, what are the impacts of tourism on Koh Phi Phi?

Koh Phi Phi over time.....

1992

It may not come as a surprise to anyone that tourism is the largest foreign exchange earner for Thai trade, and it thereby plays an unquestionably important role in the countries economy. This has lead to an increased development and economic growth but also to environmental and cultural deterioration. Many locals are edged or forced out by government or foreign entities interested and able to pay for the construction of tourist facilities.

From the destruction of coral and marine life due to water activities such as boating and scuba diving, and waste dumping by hotels and restaurants, as well as the uncontrolled building of tourist facilities on islands such as Koh Phi Phi, Koh Samui and Koh Phang, Thailand can be seen as fast approaching a crisis situation.

Koh Phi Phi, a national park, has within a very short time begun to follow the same path as Samui, regardless of its designation as a protected area. The island is known for its fancy resorts and renowned yacht club and marina.

When tourists arrive in Kho Phi Phi Island, before allowed on to the island, they are forced to pay a fee that is supposed to “keep Phi Phi clean” as the Municipal official responsible for cleanness and public relations state. What is interesting though is the fact that most of the beaches are polluted and there is garbage lying around at the beaches.



Jennifer Blunt visited Kho Phi Phi this year and was disgusted by what she saw.

“I was quite disappointed and shocked to see all the litter in the water and was surprised to see that the Thai’s were quite blatant about throwing rubbish over board. I found it quite ironic that your expected to part with 20 baht in order to actually step onto the island which supposedly is a contribution towards maintaining cleanliness of the island. I have been to many other holiday locations where payment is not required and the beach is much cleaner and noticeably maintained. I was also put off swimming in the water due to witnessing various other people urinating into the seas upon nighttime. I think that there need to be some stricter rules imposed on holidaymakers and young adults” she says.

The question is if Phi Phi island is at a risk of losing its beauty to commercialism?  Obviously tourism has a great impact in all aspects and this is why it is significant to consider a balance between nature and commerce.

Unfortunately, the very fragile coastal, marine and small island environment upon which tourism has been built has come under increasing pressure as a result of the largely uncontrolled, and hardly anticipated, tourism boom. The phenomenal amount of construction work which has taken place over the last decade or so has, in the main, proceeded unbridled by planning controls. Such building restrictions that exist have been largely ignored, often quite willfully. As a result, the coastal landscape, so important an element of the aesthetic environment, has in places been changed quite dramatically.

The marine environment has suffered equally, from the destruction of coral by anchors and scuba divers, as well as pollution from the motorboats and the continuous dumping of untreated waste that is pumped into the sea by the resorts along the shore. A Thai newspaper reported that the island cannot effectively cope with 75% of the waste that is created each day. This 75% is “burned, buried or dumped at sea”.

Along with the environmental devastation wreaked by tourism, there is also the economic effect upon poor Thais who in no way benefit – in fact suffer from the growth of tourism. Many local fishermen and their families have been forcibly removed from coastal areas to make room for new hotels and restaurants. Most of the villagers on Koh Muk, an island near Haad Chao Mai national park in Trang province, have been pushed back into the mangrove forests to make room for tourist lodgings. The villagers never owned the land, but they never needed to, until land speculators came with bills of sale from local land officials in the city. Once free to fish as they chose, these villagers now face an unsure future.

The environmental degradation taking place in relation to tourism is credited to such possible explanations as lack of information and technology, lack of skills by Thai planners in the field of ‘recreation management’, lack of authority for proper implementation, lack of coordination among government officials and departments, lack of long term thinking and planning and lack of resources.

Also inhibiting environmental protection are: the power of economic gain over all other concerns, as well as corruption in government and the predominance of outside ownership of tourist facilities, who do not have as vested an interest in the long term condition of the location as they are more free to get up and move when the tourists leave.

Increasing concern over the environmental effects of tourism have led to the recognition of the need for proper legislation. The Thai government has taken steps in this direction in the 1990s. The government is working on establishing a ‘multi-agency task force’ that would hopefully eliminate the overlap and confusion among the many departments playing a role in tourism issues. The national park system has increased to 34, 503 square kilometers.

However, much of the new legislation has yet to be successfully implemented, due to pressure from members of the industry, and the fear of harming the economic benefits reaped from this industry. Though many of the islands designated as national parks have continued to see tourist development.

Are there advantages as well as disadvantages?


Flotsam and Jetsam on the strand line.

This is a video about Phuket - but a lot of the same ideas apply to Koh Phi Phi


Task : Make a table like the one below

Fill in the table with as much detail as you can describing and explaining how tourism has both advantages and disadvantages for Koh Phi Phi. You could do some of your own research, but could start with the abstracts below.

Trash Line in Phi Phi

 Lonely Planet Koh Phi Phi

"Prior to the tsunami, the island was growing too rapidly for its existing infrastructure and fragile ecosystem to sustain. Immediately following the tsunami the Thai government put on hold any rebuilding on the island’s sand bar, and it was hoped, with the slate wiped clean, that lessons could be learned from past mistakes. Several local agencies attempted to educate developers and residents about sustainable growth, and rumours circulated that the area would be turned into a public park.

But none of these things came to pass and Ao Ton Sai now looks almost exactly as it did before 24 December 2004. In the Tourist Village, street vendors and souvenir shops are back in full swing, as are dozens of booking agencies, restaurants and dive operators. On most of the other bays, it’s business as usual.

Expat James Hood, owner of the new 007 Bar, explained it this way:
‘It isn’t like anyone actually has permission from the government to build, but it is happening anyway, and no one is doing anything to stop it. One family has a lot of influence on the island and in the provincial government in Krabi, ’ he said.

There seems to be light at the end of the tunnel, however. A new water-treatment plant, opened in 2006, should eliminate water-supply issues for now. Trash is starting to head into rubbish bins – a local bar owner has taken it upon himself to place bins on the main tourist beaches. Do your part in recycling – look for the new rubbish bins and deposit as much garbage as you can find.

And while Phi Phi may look the same as it did pre-tsunami, it certainly doesn't cost the same.
‘Ko Phi Phi is changing, there has been a drop in the backpacker population and an increase in the suitcase brigade, ’ Hood said. ‘Backpackers can’t afford to stay here anymore.’

It’s true. Although Ko Phi Phi retains a mellow backpacker vibe, cheap bungalows are few and far between, and those that exist seem overpriced for the cramped, dark and dank environs you get. The outlook is only slightly less dismal in the mid range and top-end bracket – expect to pay nearly double what you would on the mainland, for half the amenities and swankness. Why is Phi Phi so expensive these days?

For two reasons, Hood says. First, electricity is hugely expensive on Phi Phi because the island is not supplied with electricity from the mainland and has to rely on generators. Ferry and long-tail boat prices are also increasing – rates are tied to the price of petrol, so if petrol prices drop drastically in the next two years, expect prices to go down (we wish!).

On the plus side, Phi Phi is building sounder structures these days (probably another reason prices are going up). Instead of fly-by-night bungalows, Western style buildings, constructed to withstand a tsunami, are going up. Designs include open-air staircases people can use to climb onto the roof in a hurry.
And even though Ko Phi Phi will seem expensive compared to the rest of Thailand, if you compare it to other gorgeous islands around the planet, we think you’ll discover this paradise actually comes pretty damn cheap."




"....Then there are the beaches and the water. This is where Koh Phi Phi is supposed to shine. But it doesn't  From afar the blue water and white sand beaches looks like paradise. Yet when you look closer, you realize that looks are deceiving. One of the beaches is used by all the boats so it’s a no go. There is the main one in the bay opposite that a lot of people go to but when the tide goes out the water recedes out to the ocean and all that is left is dead coral, boats, and ankle deep water, which wouldn't be bad if it didn't happen during the day! This leaves the most popular beach, Long beach, which is a 15 minute walk from town. There you’ll find it packed with people vying for the decent spot of beach.

Yet unless you are on the private resorts on the north end of the island, you can’t be saved from the one thing that truly kills this island: the mass of long tail boats. There are simply too many boats and too many engines choking the water. The worst is on the beach with the pier and the best is Long Beach, but even that beach can’t escape and the fact it’s the “best,” doesn't really say much. No matter where you go, you’ll notice that the water has a funky smell to it. Or that white foamy bubbles of waste and chemicals from too many boats and engines float on the surface. Or maybe you will notice the oil slicks and the weird brown stuff in the water. Whatever you notice, you’ll notice that the water up close, just isn’t as good as it was far away and suddenly, the cool dip in that blue tropical water just doesn’t seem like such a good idea.

Ko Phi Phi, like many Thai islands, suffers from mass over development. It’s simply too small to handle all the people brought to it. Hotels are thrown up, boats brought in, and ferries arrive to fill as many rooms as possible all while coral reefs are dynamited and overfished and as many tourists as possible are brought to gawk and feed the wild monkeys and take their photo where Leonardo Di Caprio filmed “The Beach“. And since the tourists don’t complain, nothing gets changed."

What is the Future For Koh Phi Phi?

What stage of the Butler Model is Koh Phi Phi? What is its future?

What opportunities exist? Can Phi Phi develop its tourism further in a more sustainable way? What is sustainable tourism?

Chasing Ice

The BBC reports (Saturday 11 June 2013) that CO2 in the atmosphere has topped 400 ppm at monitoring stations in Hawaii.

Today was the 'Thailand Premier' of Chasing Ice 

by James Balog.


Well done to all of you that I saw in the theatre. I thought that the photography and their journey was amazing and the actual footage of the glaciers was astonishing.

I think that it is time that we stopped sitting on the fence and all did our little bits to try and conquer 'Green House' Gas emissions.

'Easy Jet to conduct volcano tests'






The Eyjafjallajokull eruption in April 2010 caused the largest closure of European airspace since World War II, with losses estimated at between 1.5bn and 2.5bn euros (£1.3-2.2bn).
The plane will carry the AVOID (Airborne Volcanic Object Imaging Detector) system, which has been developed by Easyjet, Airbus and scientists from the Norwegian Institute for Air Research (NIAR).
Ian Davies, engineering director for Luton-based Easyjet, said: "The threat from Icelandic volcanoes continues so finalising approval of the AVOID technology is as crucial now as ever, to ensure we never again see the scenes of spring 2010 when all flying ceased for several days.
"It means that in the event of another eruption and ash coming down over Europe we'll be able to determine where it is and fly in areas that are absolutely safe."

The Structure of the Earth


We found out about the layers below the Earth's surface:
      • The Crust
      • The Mantle
      • The Inner Core
      • Outer Core




New Discoveries


New research suggests that the Inner Core consists of iron alloy crystals.
They could be up to 10km high - like a crystal forest at the centre of the Earth.
(source: BBC Horizon: The Core)

The BBC reported :

Earth's core far hotter than thought

'New measurements suggest the Earth's inner core is far hotter than prior experiments suggested, putting it at 6,000C - as hot as the Sun's surface.' This means that the pressure at the earth's core is 1 million times that of the ocean floor.

So the science of plate tectonics is continuously making new discoveries.

Continental Drift


In 1915 Alfred Wegner, a German geologist, proposed the theory of Continental Drift in his book 'On the Origin of Continents and Oceans' and since then scientists have researched the movements and make up of our planet.

The Plates that make up our Planet.





Plates meet at plate boundaries where they either collide or move apart from each other.

There are 4 main types of plate boundaries.
  1. Constructive or divergent
  2. Destructive or convergent
  3. Collision
  4. Conservative or transform
We will be concerned with Constructive and Destructive plate boundaries and hot spots as this is where  most volcanic activity occurs.
