Q

Give the 5 physical environment factors that are influencing agriculture

A

Temperature- dictates the length of the growing seson
Precipitation- determines water supply and affects the growth of many plants
Wind- restricts cultivation of grain crops
Soil quality- vulnerability to leaching influences the nutritional value of the soil
Relief

Q

How are desert areas classified?

A

Deserts receive less than 250mm of rainfall per year

24
Q

Discuss the distribution of deserts globally

A

Hot deserts occur 30 degrees north and south of the equator with maximum air temperatures above 40C
Temperate deserts occur at high latitudes eg. Central Asia. Cooler than hot deserts, but still as arid

25
What is consumption directly related to?
Affluence and access to international trading markets
26
What are the two distinct characteristics of hot deserts?
High temperatures - between 43-49 | Low precipitation levels- 1-38cm annually
27
Describe the population distribution of the Sahara desert
2.5 million inhabitants 0.4 people per km2 Distribution is uneven with clusters around water sources
28
What challenges arise in the Sahara desert and how are these overcome?
Agriculture is nearly impossible due to infrequent rainfall whihc is usually in the form of heavy convectional rainstorms which can cause flash flooding and erosion Water can be drawn from oases to irrigate crops nearby. Crops can be grown in the shade of other taller food plants eg. date palms - allowed for settlement around oases Nomadic tribes allow for grazing of livestock as the animals eat the shrubbery
29
Give examples of how agriculture can occur in desert regions
Groundwater for irrigation can be accessed with motorised pumps Drip irrigation where water slowly drips onto crops, minimising evaporation Magic stones which contain water within an area and prevent soil erosion
30
Explain the impacts climate change is having on agriculture
Decreasing agricultural productivity due to reduced rainfall which has meant that areas can produce less food Increased extreme weather events which is exacerbating soil erosion Increased droughts Introduction of new pests to an area
31
What are tropical climates categorised by?
Warm temperatures- 27C | High precipitation levels of 261cm
32
Where are tropical climates located?
10 degrees south and 25 degrees north
33
How is food production in tropical climates?
Low due to leaching of soil nutrients which decreases the availability of soil for crop growing
34
What is the main role of investment banks?
To help companies raise capital by selling shares on behalf of those companies
35
What 4 things happened in the 1980s to make the financial system more global?
- ICT allowed investors greater access to information which meant they could make more educated decisions on whether to invest - Investment banks created new financial products that made foreign investment less risky - Financial deregulation - Greater range of companies got involved in finance and took on more services such as currency exchange
36
Give 3 ways that a country controls trade into and out of a country
Tariffs- taxes on products coming into the country Non-tariff barrier- rules on the quality of products coming into the country Banning certain products
37
What is a trade agreement between two countries called?
Bilateral trade agreement
38
What is a multilateral trade agreement called?
Trade agreements between several countries
39
What is the role of the World Trade Organisation?
To govern the global trade system Established in 1995 WTO sets rules on how countries can trade with each other Forum for countries to negotiate trade deals with each other and settle trade disputes
40
How have changes in transport influenced globalisation?
Improved transportation systems through high speed rail networks and shipping has meant that products can get to locations quicker and more easily than ever before
41
Explain the importance of containers
Allowed for more efficient packing of goods into the ship Easy to transport onto other forms of transport so it has meant that there has been an increased speed of distribution within countries Cheaper and easier transport
42
Explain the importance of communication satellites
Cheap wireless communication between two areas | Have increased the connectivity of rural and urban areas
43
What are optical fibre cables and what do they allow?
Signals of light to transmit information between two locations almost instantly
44
Give 4 ways that companies have become more efficient
Companies supply chains have become more global- supplier and factory may be in different locations which minimises costs Economies of scale- large businesses can buy in bulk and use specialised production lines to cut down manufacturing costs Outsourcing- paying another firm to do part of the production process to save money Change in working contracts- don't have to pay a fixed yearly wage
45
Why has globalisation increased global security?
Countries reliant on trade with each other are less likely to want to go to war as they require goods from each other to thrive Countries work together to improve security ie through NATO- deter common threats
46
Why has globalisation decreased global security?
Developed countries can intervene in conflicts in developing countries to secure resources such as oil Provided a platform for exchange of information between people such as terrorists
47
Use SEEP to suggest ways that globalisation causes interdependence
Social- greater connection between people creates greater social interdependence- ie. through migration Economic- countries rely on each other for economic growth Environmental- rely on each other to solve environmental issues and look after the environment Political- countries are reliant on each other to solve issues that cannot be solved by one country in isolation
48
Describe benefits of unequal flows of people
Causes economic growth in host country by migrants doing jobs that countries citizens can't do or won't do Causes economic growth in the country of origin as migrants often send remittances which can significantly increase the amount of capital within an economy
49
Describe the problemsassociated with unequal flow of people
Inequalities- less developed countries suffer from brain drain and this reinforces inequalities between countries Conflict- low skilled migrants are happier to work for less money than low skilled locals so it may depress wages for local population which causes conflicts between the migrants and locals Injustice- migrant workers are made to work in dangerous conditions for little money
50
Describe the benefits of unequal flows of money
Foreign Direct Investment allows for foreign companies and countries to take advantage of cheap raw materials and low labour costs Host country can benefit from capital and expertise through FDI Foreign aid can be used to improve living standards or rebuild local infrastructure after a disaster
51
Describe the problems associated with unequal flows of money
Foreign aid can create a dependency which gives governments little incentive to change their own countries FDI can force out local business Foreign aid can find its way to armed groups and to help fund conflict Companies may pressure governments of less developed countries to pass laws that make it easier for companies to invest there
52
What is neo-liberalism?
Developed countries thinking that economy would work better without state intervention Maximum economic growth would only occur if barriers to trade were removed and state owned companies were privatised
53
Benefits of neo-liberalism
Increased free trade More development within countries Less conflict between some countries
54
Problems of neo-liberalism
Started in developed countries and has spread to developing countries- tend to concentrate wealth in hands of few people Conflict TNCs and governments may argue that neo-liberalism is the best way to develop despite the poor working conditions and degradation of the environment
55
Problems of improved technology
Repressive governments have used weapons technology sold to them by developed countries to stop protests from their own people Developed countries have greater access to technology- increases inequalities between countries
