WEBVTT 00:00:00.500 --> 00:00:03.975 Welcome to GCSE A Q A Geography revision. 00:00:04.125 --> 00:00:07.551 Topic G 14: The changing economic world. 00:00:07.701 --> 00:00:12.555 Use your school’s selected case studies if they differ from these revision examples. 00:00:15.233 --> 00:00:19.475 Development is improvement in people's opportunities and living conditions. 00:00:19.625 --> 00:00:26.610 Economic growth can help, but a rising national income does not automatically improve everyone's health or security. 00:00:29.267 --> 00:00:35.814 H I C, L I C and middle-income classifications use income thresholds that are updated over time. 00:00:35.964 --> 00:00:42.055 N E E describes a rapidly changing economy; it is not a fixed World Bank income category. 00:00:44.733 --> 00:00:51.057 Gross national income (G N I) includes income earned by a country's residents at home and abroad. 00:00:51.207 --> 00:00:56.718 G N I per head divides it by population and is an average, not each person's wage. 00:00:59.400 --> 00:01:04.795 G N I per head can hide inequality, informal work and regional differences. 00:01:04.945 --> 00:01:10.651 Purchasing-power comparisons adjust for different price levels but still have measurement limitations. 00:01:13.333 --> 00:01:17.108 Birth and death rates are annual births and deaths per thousand people. 00:01:17.258 --> 00:01:22.643 A low death rate alone does not prove high development because population age affects it. 00:01:25.300 --> 00:01:29.775 Infant mortality measures deaths before age one per thousand live births. 00:01:29.925 --> 00:01:33.832 It can indicate access to nutrition, safe water and healthcare. 00:01:36.500 --> 00:01:42.993 Life expectancy is the average number of years a newborn would live if current mortality patterns continued. 00:01:43.143 --> 00:01:45.681 It is not the age every person reaches. 00:01:48.333 --> 00:01:55.831 People per doctor indicates potential access to healthcare: fewer people per doctor usually means more doctors are available. 00:01:55.981 --> 00:01:59.187 Rural access, cost and quality can still differ. 00:02:01.867 --> 00:02:07.124 Literacy rates and access to safe water indicate opportunities and basic services. 00:02:07.274 --> 00:02:13.005 Check definitions, age groups, dates and how the data were collected before comparing countries. 00:02:15.667 --> 00:02:22.770 The Human Development Index (H D I) combines health, education and income into a score between zero and one. 00:02:22.920 --> 00:02:27.541 A higher value suggests higher development but hides differences within a country. 00:02:30.200 --> 00:02:32.333 Use several indicators together. 00:02:32.483 --> 00:02:40.183 A country's national average can conceal poorer regions, gender inequalities and differences between rural and urban populations. 00:02:42.833 --> 00:02:50.160 The Demographic Transition Model shows a typical sequence of changes in birth and death rates as living conditions change. 00:02:50.310 --> 00:02:53.836 It is a model, not a timetable every country must follow. 00:02:53.986 --> 00:02:56.119 Changing birth and death rates. 00:02:56.269 --> 00:03:00.743 The gap between birth and death rates indicates natural increase or decrease. 00:03:00.893 --> 00:03:05.001 Stage 5 has births below deaths; migration is not shown. 00:03:09.667 --> 00:03:14.691 In stage 1, birth and death rates are both high, so population grows slowly. 00:03:14.841 --> 00:03:19.661 Poor healthcare and unreliable food supplies can produce high mortality. 00:03:22.333 --> 00:03:26.125 In stage 2, death rates fall while birth rates remain high. 00:03:26.275 --> 00:03:30.244 Better water, food and healthcare allow rapid natural increase. 00:03:32.900 --> 00:03:40.416 In stage 3, birth rates fall as education, contraception, urban living and changing family expectations develop. 00:03:40.566 --> 00:03:42.443 Natural increase slows. 00:03:45.100 --> 00:03:50.047 In stage 4, birth and death rates are both low, with relatively slow growth. 00:03:50.197 --> 00:03:53.609 Migration can still change the population substantially. 00:03:56.267 --> 00:04:00.739 In stage 5, births can fall below deaths, producing natural decrease. 00:04:00.889 --> 00:04:05.923 An ageing population may raise demand for healthcare and reduce the working-age share. 00:04:08.600 --> 00:04:12.082 Development and population change influence each other. 00:04:12.232 --> 00:04:19.237 Education and health can change family size, while a large young population increases demand for schools and jobs. 00:04:21.900 --> 00:04:27.136 Physical constraints include drought, difficult terrain, landlocked location and hazards. 00:04:27.286 --> 00:04:33.707 These can raise transport costs or disrupt farming, but they do not determine a country's future by themselves. 00:04:36.367 --> 00:04:44.184 Economic constraints include dependence on a few low-value exports, limited infrastructure, debt and weak access to investment. 00:04:44.334 --> 00:04:48.169 Falling export prices reduce money available for services. 00:04:50.833 --> 00:04:57.317 Historical influences include colonial extraction and borders, unequal trading relationships and conflict. 00:04:57.467 --> 00:05:01.071 Their effects interact with later decisions and institutions. 00:05:03.733 --> 00:05:09.653 Uneven development produces differences in income, healthcare, education and life expectancy. 00:05:09.803 --> 00:05:14.160 Poorer households are often more vulnerable to hazards and rising prices. 00:05:16.833 --> 00:05:20.633 International migration can offer jobs and education. 00:05:20.783 --> 00:05:27.555 Money sent home, called remittances, supports families, but losing skilled workers can weaken essential services. 00:05:30.233 --> 00:05:33.833 Investment can fund transport, electricity and businesses. 00:05:33.983 --> 00:05:41.193 Benefits depend on whether it creates useful local employment and whether profits and tax revenue remain available locally. 00:05:43.867 --> 00:05:48.612 Manufacturing adds value to raw materials and can create supplier jobs. 00:05:48.762 --> 00:05:53.711 Pollution controls, worker protection and training influence the quality of development. 00:05:56.367 --> 00:06:01.590 Tourism earns foreign currency and supports hotels, guides, farms and transport. 00:06:01.740 --> 00:06:07.371 Profits leaking abroad, seasonal jobs and environmental damage can limit its benefits. 00:06:10.033 --> 00:06:16.858 Aid may be emergency relief after a disaster or longer-term support for health, education and infrastructure. 00:06:17.008 --> 00:06:23.043 Bilateral aid comes from one government; multilateral aid involves international organisations. 00:06:25.700 --> 00:06:32.387 Aid can improve services, but unsuitable projects, conditions, corruption or dependence can reduce its value. 00:06:32.537 --> 00:06:37.005 Local participation and maintenance planning improve lasting benefits. 00:06:39.667 --> 00:06:42.995 Intermediate or appropriate technology is affordable, 00:06:43.145 --> 00:06:46.622 maintainable and suited to local skills and conditions, 00:06:46.772 --> 00:06:51.195 such as a repairable hand pump rather than an unsupported complex system. 00:06:53.867 --> 00:06:58.566 Fairtrade schemes aim to improve producers' trading terms and working conditions. 00:06:58.716 --> 00:07:03.517 Certification and market access can help, but not every farmer is included. 00:07:06.167 --> 00:07:09.653 Debt relief releases money previously spent on repayments. 00:07:09.803 --> 00:07:16.371 Its development effect depends on how the released funds are used and whether new unsustainable borrowing follows. 00:07:19.033 --> 00:07:26.051 Microfinance offers small loans and other financial services to people excluded from conventional banking. 00:07:26.201 --> 00:07:31.055 It can support businesses, but repayments and interest can create difficulties. 00:07:33.733 --> 00:07:36.249 No single strategy closes the gap. 00:07:36.399 --> 00:07:42.127 Compare cost, scale, fairness, local control and the time needed for benefits to develop. 00:07:44.800 --> 00:07:49.429 Primary activities obtain natural resources, such as farming and mining. 00:07:49.579 --> 00:07:54.995 Secondary activities manufacture or build; tertiary activities provide services. 00:07:55.145 --> 00:07:58.779 Quaternary work involves knowledge, research and information. 00:08:01.433 --> 00:08:06.047 Economic development often changes the balance of employment between sectors. 00:08:06.197 --> 00:08:11.550 A fall in farming's share does not necessarily mean total agricultural production falls. 00:08:14.200 --> 00:08:21.185 Manufacturing can create a multiplier effect: workers spend wages locally and factories buy from other firms. 00:08:21.335 --> 00:08:24.683 Skills and infrastructure can attract further investment. 00:08:27.333 --> 00:08:32.232 A transnational corporation (T N C) operates in more than one country. 00:08:32.382 --> 00:08:37.231 It may bring capital, jobs, technology, training and access to world markets. 00:08:39.900 --> 00:08:47.888 T N C disadvantages can include profits sent abroad, insecure work, environmental damage and pressure for low taxes. 00:08:48.038 --> 00:08:51.523 Effects vary between firms, contracts and regulation. 00:08:54.200 --> 00:09:00.791 Country case studies need political stability, culture, trade links and environment as well as industries. 00:09:00.941 --> 00:09:05.933 Explain how development changes people's lives, including people left behind. 00:09:08.600 --> 00:09:13.731 De-industrialisation is a decline in industry's share of employment or output. 00:09:13.881 --> 00:09:21.782 Automation, overseas competition, changing demand and government policies have contributed to the loss of some traditional jobs. 00:09:24.433 --> 00:09:29.893 Globalisation links economies through trade, investment, migration and information. 00:09:30.043 --> 00:09:35.748 It creates export markets and competition; some tasks can move to countries with lower costs. 00:09:38.400 --> 00:09:43.411 The U K has a largely post-industrial economy dominated by services. 00:09:43.561 --> 00:09:50.753 Finance, education, healthcare, digital work and research are important, while manufacturing continues to operate. 00:09:53.433 --> 00:09:58.797 Science and business parks cluster firms near universities, skilled workers and transport. 00:09:58.947 --> 00:10:04.397 Shared expertise can encourage innovation, but housing and infrastructure costs can rise. 00:10:07.067 --> 00:10:12.543 Industry affects landscapes through land use, traffic, waste, water demand and emissions. 00:10:12.693 --> 00:10:18.655 Environmental assessment, efficient processes and reuse of brownfield sites can reduce damage. 00:10:21.333 --> 00:10:29.397 Population growth in accessible rural areas can support services but increase house prices, congestion and pressure for building. 00:10:29.547 --> 00:10:34.773 An area losing younger residents can face school closures and an ageing population. 00:10:37.433 --> 00:10:45.592 Road and rail improvements can connect jobs and markets, but construction costs, habitat damage and carbon emissions need evaluation. 00:10:45.742 --> 00:10:48.706 A proposed scheme is not a completed benefit. 00:10:51.367 --> 00:10:57.861 Ports handle imports and exports, while airports connect passengers and high-value or time-sensitive freight. 00:10:58.011 --> 00:11:03.215 Expanding capacity can support trade but increase noise, emissions and land pressure. 00:11:05.867 --> 00:11:14.825 The north to south divide describes broad regional inequalities, particularly between prosperous London and south-east England and many other areas. 00:11:14.975 --> 00:11:18.152 There are wealthy and deprived places on both sides. 00:11:20.833 --> 00:11:27.403 Training, regeneration, improved transport and regional investment can attempt to reduce inequalities. 00:11:27.553 --> 00:11:31.722 Benefits depend on whether local people can access new jobs and housing. 00:11:34.400 --> 00:11:40.511 The U K is linked globally through trade, migration, culture, transport and electronic communication. 00:11:40.661 --> 00:11:44.699 Digital connections allow services to be provided across borders. 00:11:47.367 --> 00:11:50.929 The U K left the European Union in 2020. 00:11:51.079 --> 00:11:56.796 Trade and cooperation continue, but being a trading partner is different from being an E U member. 00:11:59.467 --> 00:12:04.627 The Commonwealth connects independent countries through cooperation and historical links. 00:12:04.777 --> 00:12:10.002 Membership does not create one shared government or automatically remove trade barriers. 00:12:12.667 --> 00:12:19.119 Jamaica is a Caribbean island with beaches, warm conditions, cultural attractions and mountainous landscapes. 00:12:19.269 --> 00:12:23.983 Tourism connects places such as Montego Bay to international visitors. 00:12:26.633 --> 00:12:34.421 Visitor spending supports hotels, guides, restaurants and transport, while suppliers gain demand for food, repairs and building work. 00:12:34.571 --> 00:12:38.121 These indirect benefits explain the multiplier effect. 00:12:40.800 --> 00:12:46.292 Foreign-currency earnings can help pay for imports, and public revenue can support services. 00:12:46.442 --> 00:12:51.860 Benefits are greater when local workers and suppliers retain a substantial share of spending. 00:12:54.533 --> 00:12:59.378 Imported supplies and overseas ownership can send income out of the country. 00:12:59.528 --> 00:13:04.851 Seasonal employment and low wages limit how far tourism reduces inequality. 00:13:07.533 --> 00:13:13.270 Tourism is exposed to storms, changing visitor demand and international economic shocks. 00:13:13.420 --> 00:13:20.896 Development also needs environmental protection and other sources of livelihoods rather than dependence on visitors alone. 00:13:23.567 --> 00:13:30.839 Nigeria lies in West Africa, with a coast on the Gulf of Guinea and neighbours including Benin, Niger, Chad and Cameroon. 00:13:30.989 --> 00:13:36.918 Its population, markets and energy resources make it important regionally and internationally. 00:13:39.600 --> 00:13:42.755 Nigeria is a culturally diverse federation. 00:13:42.905 --> 00:13:52.407 The wetter south and drier north create contrasting farming and environmental conditions; conflict and insecurity affect some regions more severely than others. 00:13:55.067 --> 00:13:59.695 Nigeria gained independence from Britain in 1960. 00:13:59.845 --> 00:14:07.886 Its later economic development reflects oil revenues, changing policies, urban growth and links with global trade and investment. 00:14:10.567 --> 00:14:16.859 Agriculture remains important for livelihoods, while services and manufacturing provide urban employment. 00:14:17.009 --> 00:14:22.225 Oil is especially important for export earnings, even though it is not the whole economy. 00:14:24.900 --> 00:14:30.766 Manufacturing food products, cement and other goods adds value and can support supplier jobs. 00:14:30.916 --> 00:14:35.449 Unreliable power and transport increase costs and limit opportunities. 00:14:38.100 --> 00:14:49.971 The Shell Petroleum Development Company joint venture provides a historical T N C example in the Niger Delta, including the period examined by U N E P's 2011 report. 00:14:50.121 --> 00:14:51.337 Investment, 00:14:51.487 --> 00:14:54.452 technology and export links can create benefits, 00:14:54.602 --> 00:14:59.038 while profits leaving the country and pollution risks show why regulation matters; 00:14:59.188 --> 00:15:02.365 do not assume historical ownership remains current. 00:15:05.033 --> 00:15:10.771 Oil exports link Nigeria to overseas buyers, and imported machinery supports production. 00:15:10.921 --> 00:15:17.928 Dependence on oil earnings exposes public finances and foreign currency income to changing world prices. 00:15:20.600 --> 00:15:26.699 Nigeria cooperates through organisations including E C O W A S and the African Union. 00:15:26.849 --> 00:15:33.089 International trading and political relationships connect it to regional neighbours and partners beyond Africa. 00:15:35.767 --> 00:15:40.971 Aid and development finance support areas such as health, education and infrastructure. 00:15:41.121 --> 00:15:50.293 Emergency humanitarian assistance is especially important where conflict displaces people; loans and grants have different repayment implications. 00:15:52.967 --> 00:16:03.567 U N E P's 2011 Ogoniland assessment documented serious oil contamination of soil, water and ecosystems in part of the Niger Delta. 00:16:03.717 --> 00:16:10.745 This is evidence of environmental costs of extraction, not a claim that every Nigerian region has the same damage. 00:16:13.400 --> 00:16:18.582 Development creates some jobs, services and opportunities but benefits are uneven. 00:16:18.732 --> 00:16:27.263 Poverty, insecure employment and gaps in electricity and healthcare show why growth alone does not guarantee improved living conditions for all. 00:16:29.933 --> 00:16:37.889 Cambridge illustrates a knowledge-based cluster: the university, research institutes and science parks connect skilled workers and firms. 00:16:38.039 --> 00:16:42.976 Growth brings innovation and employment alongside housing and transport pressures. 00:16:45.633 --> 00:16:51.787 Nissan's Sunderland factory illustrates modern industrial production using renewable electricity. 00:16:51.937 --> 00:17:02.997 Wind turbines and a solar farm, including the solar installation opened in 2016, supply some of the plant's demand and reduce dependence on fossil-fuel generation. 00:17:05.667 --> 00:17:13.676 Renewable power can reduce manufacturing emissions, but it does not remove impacts from materials, transport or the use of finished vehicles. 00:17:13.826 --> 00:17:18.241 Assess the whole production system rather than calling a factory impact-free. 00:17:20.900 --> 00:17:26.157 South Cambridgeshire is a rural-growth example linked to the Cambridge employment area. 00:17:26.307 --> 00:17:32.781 New residents support demand for services while housing costs and commuting can pressure existing communities. 00:17:35.433 --> 00:17:43.090 The Western Isles provide a contrasting rural example of long-term depopulation and ageing pressures in some communities. 00:17:43.240 --> 00:17:48.881 An archipelago-wide trend does not mean every island or settlement changes in the same way. 00:17:51.533 --> 00:17:57.954 The Elizabeth line opened in 2022 and connects east to west rail routes through central London. 00:17:58.104 --> 00:18:06.594 It is a completed transport example; assess accessibility benefits alongside cost rather than treating all future extensions as complete. 00:18:09.267 --> 00:18:14.204 London Gateway on the Thames illustrates port capacity and logistics investment. 00:18:14.354 --> 00:18:21.265 Warehousing and shipping connections support trade but also generate land use, traffic and environmental pressures. 00:18:23.933 --> 00:18:31.378 Regional transport investment, skills programmes and brownfield regeneration can aim to reduce the north to south divide. 00:18:31.528 --> 00:18:36.935 Judge success using jobs, access and living standards, not investment totals alone. 00:18:39.600 --> 00:18:42.265 That completes The changing economic world. 00:18:42.415 --> 00:18:45.761 Revisit the notes and test yourself on the revision website.
