Globalisation Revision Session Weds 25th April

Dear All, Please use the form below to send in your questions on Globalisation. This session will start at at 7:30 on Wednesday evening, and YOUR QUESTIONS WILL NOT APPEAR!!! I have publishing control, so I will get through all of them, but in order and only when the event starts. It will run for about an hour, and the section of the syllabus to be covered is produced below:

Global social and economic groupings

The concept of the North/South divide, and its relationship to the development continuum.
Reasons for the social and economic groupings of nations, with particular reference to the European Union.

The consequences of the groupings of nations.

Aspects of globalisation Transnational corporations (TNCs): characteristics and spatial organisation. Reasons for the growth and the spatial organisation of transnational corporations (TNCs).
Case study of one TNC should be undertaken.
Social, economic and environmental impacts of TNCs on their host countries, and their countries of origin.

Development issues within the world (each to be studied with reference to contrasting areas of the world) “Trade versus aid”. “Economic sustainability versus environmental sustainability”. “Sustainable tourism, myth or reality”

.

Development Revision Workshop

Hello Readers,

Tonights topic is development, so please have some questions ready, remember, your questions will not appear immediately, I publish them when i am logged in and ready to answer each in turn, so please be patient, and of course, you can replay this workshop at anytime up until the exam.

Next weeks topic will be Globalisation, followed by Tectonic Theory, then Case studies, Climatic Case studies, and finally, Climate Change. You will be able to submit questions for these workshops in advance, I shall see you at 7:30!

Holderness Case Study

Dear Lower Sixth!

Here is the PP from todays lesson:

The Holderness Coastline

Your two major case studies for the coastal module are Holderness and Lyme Regis, where for both, you need to understand the reasons for, and the methods which have been used for protection. For both, the focus is on coastal erosion and management, and the area is Holderness in East Yorkshire. This is one of the most rapidly eroding coastlines in the UK, and can retreat as fast as 2m a year. The stretch of coastline you will be studying runs from Flamborough Head in the North, to Spurn Point i the South, the sediment underlying much of Yorkshire is Glacial till, and there are high grounds to the West which mark the western limit of Ice sheets during the last ice age.

So, what is coastal erosion? Let the Environment Agency explain!

Rock type is important, Till is a very immature rock, it forms under ice sheets and in Yorkshire is as young as 50 000 years old. The rock is soft, unconsolidated and composed of mud's and some sands with pebbles in it:

As such, the rock is very easy to erode, particularly over the winter when wave strength is at its highest, as seen in this short clip of the waves over winter breaking against the soft till:

There are some good intro videos to the case study already made for us, so here's a good basic one:

This is an excellent clip showing a time lapse photo project over a year in Yorkshire showing how much erosion and deposition takes place:

Why is this such a problem for Holderness? Well, you will get plenty from the video notes, including a rather interesting lady who loses her cows over the edge of the cliff. But Holderness is a real tourist honeypot site, there are numerous holiday parks and mobile home sites right on the coast, unfortunately they are at serious risk and many have already been lost to the sea:

There are of course defences in place, but many are now ageing and in need of replacement, such as these groynes at Hornsea which are not overly attractive to tourists wishing to use the beach:

Yet, groynes are a relatively simple form of defence and the tourists would rather have a beach with groynes than none! They do however cause Terminal Groyne Syndrome, a rather painful affliction if you are a beach, which sees the sand piling up in some areas, and therefore being depleted in others (remember sediment cells are systems). The worst example of this is Mappleton, and it has resulted in certain areas of the coastline being protected through an aggressive Hold the line strategy, and some being lost through managed retreat with the creation of the five new bays. 

The decision has been taken to defend Mappleton at the expense of the down drift towns such as Cowden (The former location of the Earle Farm which has now largely fallen into the sea).

This clip is part of the Blue Peter from 1994 that focused on Mrs Earle loosing her farm to the sea, much of this farm has now gone, as a result of the protection installed at Mappleton to protect the road and the village. This is an excellent example of a cost-benefit analysis, it cost less to build two groynes at £1 million each in Mappleton, than to relocate the road and the residents, but the Earle farm paid the price in 1997. To add to their misery, they were then asked to pay for the demolition costs at their farm as the building was slowly falling into the sea. Quite often, insurance companies do not pay for claims as a result of what is known as a "gradually operated cause", as in coastal erosion, so for many of these homes at risk from receding coastlines, there is no compensation.
This is an excerpt from a geography revision forum on the topic:

• Coastal erosion - Holderness coast, Yorkshire.
  Tip: Remember the shape of the coastline as the man with a beard
  • Main rock is boulder clay so cliffs are unstable. Other main rock is chalk
  • Cliffs retreat by 2m a year
  • 50 villages that exist during the medieval times are lost today
  • 5 km of land already lost
  • Major features (in order from north to south) – Flamborough Head, Holderness Coast and Spurn Head
• The Great Debate – Protect Mappleton/ B 1242?
  • Problem: Protecting an area of land always mean greater pressure and coastal erosion on neighbouring stretches of coast

Hornsea is a big town so groynes are necessary. However this means greater coastal erosion will occur in the south; meaning it would affect Mappleton. Mappleton is a small village but an important road, the B1242, runs through it and losing it would mean compensation of millions of pounds. Planners decided to protect it, but this would mean the coastal area down further south will suffer from greater erosion (10 metres a year).
FOR Build rock groyne - trap sand at Mappleton - southern coast and farms destroyed

• One example would be Sue Earl, a farmer in Great Cowden. Although she had lost a lot of land every year, she was determined to keep the farm running. Eventually the sea will claim the whole farm so she had to give up, especially when the farmhouse went too.

AGAINST Do nothing - Mappleton and parts of B 1242 destroyed; huge compensation - sands continue protect southern coast and farms

A new development is that permission has been given for a huge offshore wind farm just offshore from Spurn

Your comparative case study will be Lyme Regis, which we will cover on the trip, but in order to prepare yourself here is a video explaining why Lyme is an important site, not only for the town itself, but also for the South West:

 

A glossary for you!

Dear Upper Sixth,

here is the glossary for you to complete for all three modules, leave a query on the FB page if you cant find any! Also, if you are resitting 4B, you have an email you should read!
