sahara revision
challenges
extreme temperatures
working there will be both physically and mentally draining because of heat. it can also drop to below 0 degrees at night
-
-
difficulty to build
difficult to get supplies because of accessibility, builders working in the heat, lack of water ect
-
opportunities
mining for minerals
Mining for minerals eg oil, phosphate which makes fertilisers and a little bit of gold. Mining contributed to 35% of Morocco's exports in 2011.
Miners get wages and pay taxes which goes towards schools, hospitals, roads etc, it benefits all. Miners will be able to provide for their families.
tourism
multiplier effect = one economic activity benefits others eg shops, cafes, restaurants.
-
energy production
eg solar panels the sahara gets 12 hours of sunlight everyday and on average 330 sunny days out of 360.
World's largest solar farm in Morocco is 3,500 football pitches big. No co2, clean and cheap. Job opportunities for people - well paid. Solar panels rotate with the sun to absorb as much as possible. It is reliable.
agriculture
in Morocco 130,000 football pitches worth of land turned into agriculture. and they produced 90,000 dates in 2017 which were exported all over the world and is camel food.
Breeding camels for milk, meat, cheese, dairy products ect.

solutions
water management
Hose pipes are laid across the soil and the water slowly drips out through little holes, the plant roots then absorb this
Water won't evaporate because it’s close to soil, less water loss and bigger/better crops meaning more income
Farmer will then pay tax which the government will spend on schools, hospitals ect
intermediate technology
stone lines - They work with the contours of the ground to build walls which capture the water therefore keeping the nutrients in the soil. it is low cost, low tech and done by local peolple
zai farming - Plants are left in a open hole where it can capture rainwater. it is low cost, low tech and done by local people
the green wall
Planting acacia trees which are drought resistant - roots hold soil in place stopping erosion across the southern end of the sahara
Fights the effects of climate change and stops desertification. Senegal has planted 11 million trees already. trees provide shade for people and crops and the leaves provide compost increasing crop yield
causes
climate change
Some places are getting hotter with an increase in droughts and other places are becoming wetter with an increase in floods. climate change is the change in our weather patterns. it is man made and can lead to the loss of biodiversity
-
removal of wood
there's no electricity in the sahara so people turn to wood to cook over and keep warm as the temp can drop to below 0 degrees at nights
soil erosion
beaches the land is bare without any tree roots to hold the soil in place the rain washes the nutrients away. this is called soil erosion
