OCR A2 Geography 2016Watch
I'll be posting revision notes and sources for:
-Development & Inequality,
-Population & Resources,
-Earth Hazards (flooding, tectonics and mass movements).
-Geographical Skills - notes will be very much based on North Wales and the investigation regarded Sand Dune succession at Morfa Harlech.

[Issues] Population and Resources:-Over population / Under population.
-Unsustainable rates of natural increase / youthful and ageing population.
-Resource depletion.-Unsustainable environmental consequences of resource extraction.
-Inefficient distribution and unfairness of resource availability leading to poverty or excessive wealth.
[Issues] Development and inequalities:-Youthful population - high number of young dependents.
-The growing gap between the beneficiaries of globalisation and the countries in the global development periphery, Sub-Saharan Africa.
-Internal inequalities in living standards within a region or a country.
-Development gap leading to inequality within quality of life.
-Difficulties in creating economic development - influence on social inequalities.
- Overconsumption can be managed through political influences such as the ‘Common Fisheries Policy’ which restricts the total allowable catch. This helps to balance the supply and the demand of the resource.
- Technological advancements such as desalination plants in China – removes salts and minerals from saline water and is used to provide more water for crops.
- Increased mining depth from water drainage systems - offshore drilling into deeper water + 3D drilling mainly in the North Sea.
- Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside.
- Reallocation of resources, for example in China,‘South-North project’ which involves transferring water from the Yangtze to the northern rivers as it’s significantly drier.
- Anti-Natalist policies like ‘China’s One Child policy’. Reduces the demand for resources as the population decreases.
- Education in regards to family planning, birth control, contraceptives, etc
- Education regarding conservation and efficiency,for example use of recycling.
- Technological advancements to minimise resource consumption – for example the toilet flush, new designs of the toilet – Dual Toilet Flush – offers a low volume and high volume flush.
- Genetic Modification of crops – a gene from xerophytic plants is inserted to crop plants to allow them to grow in drought conditions, such as in Sub-Saharan Africa.
- Green Revolution in India – using high yielding crops – production of wheat and maize tripled.
Uranium development - used to be used in glass and ceramic industries until its fissile products were discovered, it’s now a valuable resource in regards to Nuclear Power. Canada and Australia produce 60% of the world’s supply.
Smelting minerals - bronze (alloy of tin and copper) was replaced by iron and then replaced by bauxite through smelting by electrolysis- through technological advances it has become a valuable resource, globally.

And any useful tips on 10 and 30 markers would be much appreciated. Thanks!
