Irrigation Projects Crops need water to grow. They normally get the water when it rains. In places where there is little rainfall, irrigation is needed. Irrigation means pumping water from a river or lake to farmland. The water is then sprinkled over the crops. Q. Why is Irrigation common in the South of France and not in Ireland?

Case study – irrigation in France Languedoc has a Mediterranean climate with hot dry Summers and mild wet winters It WAS unsuitable for agriculture as the ground was too dry. The Canal Phillippe Larmour was built in the 60’s. It originates at the mouth of the Rhone river and extends along the coast branching into the valleys.

Positive effects Farmers diversified – wide variety of crops (cucumbers, olives, sunflowers, apricots). Farmers sell to tourists – businesses and profits grow. Wine making expanding – Languedoc now produces 1/3 of France’s wine. Languedoc now a wealthy region – farmed intensively Fastest growing agricultural region in France (one of Europe’s fastest).

Negative effects Salinisation of some areas – build up of mineral salts. It can lead to soil infertility. Pollution due to overuse of pesticides and fertiliser.

Oil – A Non-Renewable Resource Our world uses vast amounts of energy. 25% of the population uses 85% of the earths resources. Oil is a non-renewable resource. It is finite Oil is a very important source of energy in our world today. It is called Black gold as it is one of the most valuable commodities in the world.

Uses of oil • Domestic • Industrial • Transport fuel

Advantages & disadvantages 1. It’s a clean fuel does not emit much smoke. 2. It’s efficient and gives off lots of energy. 3. Easy to transport pipeline or tanker 4. By-products include paint and plastics • Oil spills kill wildlife • It emits greenhouses gases when burned. • It is finite – will run out in 100 years. • The price fluctuates – it has a huge impact on economies.

Case study: Oil & gas in Ireland 1970’s Govt. granted licences to oil companies

Case study: Oil & gas in Ireland 1970’s Govt. granted licences to oil companies to search for oil in the Irish sea. The sea was divided into blocks, which are rented to gas companies. Test holes are drilled to see if there is enough oil or gas to bring ashore.

Irish “finds” • Waterford: Oil - Not enough to bring ashore. • Kinsale: Gas

Irish “finds” • Waterford: Oil - Not enough to bring ashore. • Kinsale: Gas 1971, brought ashore by pipeline, sold to Bord Gais for distribution. In decline, smaller finds now being extracted. • Corrib: Gas. Mayo 1996. Could supply 60% of Ireland's needs. Huge controversy “shell to sea” campaign.

Case study – Oil in Saudi Arabia Poor until 1930 – Bedouin nomads. 1938 oil discovered – oil industries created. Saudi became world’s largest exporter (owns 10%). Bedouin lifestyle replaced by huge wealth. Now – excellent standard of living (health, education infrastructure are very good) 1938

Culture in Saudi Arabia follows Islamic traditions, cultures and laws. Their culture id very different to ours. • Alcohol and pork are banned. • Unmarried men and women cannot be in public together. • Women must be fully covered in public • Women have limited social rights, they were granted the right to drive this year! • The majority of women do not work outside the home and often marry young. Saudi Arabia has ABSOLUTE MONARCHY – the King rules according to Islamic law.

Raised Bogs occur mainly in the central plain of Ireland. They are very deep

Raised Bogs occur mainly in the central plain of Ireland. They are very deep bogs. Their depth can be over 8 -12

Bord na Mona Set up by government in 1946 to exploit peat commercially. Modern machinery helped speed up the process. Bord na mona mainly exploits RAISED bogs. Machinery A ditcher: Drains the bog, it has wide tracks to prevent sinking. A grader: Levels the surface of the bog Tractors lay light rail tracks which transport harvested peat out.

The Importance of Peat is very important to our economy. Bord na Mona employs 2000 people. Many of these jobs are in regions where job creation is difficult. Peat is used to generate electricity. Peat is exported to other EU countries.

Peat – What next? • Continue to exploit until it runs out. Saving money

Peat – What next? • Continue to exploit until it runs out. Saving money on imported fuels. • Preserve bogs in their natural state as a habitat for native plants and animals. • Promote as a tourist attraction for future generations • Bord na Mona plans to preserve 20, 000 hectares of raised bogs and return them to wetlands and as eco-park developments.

The future of cutaway bogs • Used to grow coniferous trees – timber products

The future of cutaway bogs • Used to grow coniferous trees – timber products • Preserved as wetland habitats. • Used for wind farms. • Cutaway bogs are level and well drained, suitable for building and infrastructure.
