Variations in climate, land degradation, population, growth and water pollution.
2. What is a drought? What type of hardships do you think that a drought could cause if you were living in a village in a poor country such as Ethiopia?
A drought is like no rain and it's dryness. They can't grow any plants because of dryness.

A drought is like no rain and it's dryness. They can't grow any plants because of dryness.
3. How does land degredation affect the supply of fresh water?
The soil is like a sponge keeping the rain.
4.
(a) What is El Nino?
El Nino is like a drought but it comes every 3 to 5 years in the Pacific Ocean of the cost of Peru. Then you get dryness. Then it won't observe the rain and it becomes flooding and it also causes drought.
(b) Why does El Nino often cause drought in Australia?
Because it goes the reverse way as a result there are no moist.
5. Observe the map showing the global effects of El Nino in 1982-83.

(a) What effects does El Nino have on the availability on fresh water?
It takes away the moisture and availability of water is greatly decreased.
(b) Name the countries and describe the problems that arose from decreased rainfall caused by El Nino.
Africa- Reduced corn crop in sub-Saharan region
China- Agricultural land under threat from drought in northern regions and flooding in southern regions.
Indonesia- High air pollution levels, following forest flies.
Philippines- Lower rice harvest following drought.
Papua New Guinea- Drought -related failure of food crops, leading to famine conditions requiring food aid.
Australia- Wheat exports threatened by drought conditions across grain-growing areas, particularly New South Whales.
Unite States- Rainfall above normal in north-western states (double the historical avaerages)
Colombia- Fishing operations affected by lower catch (down 20%)
Peru- Flooding (also in Chile) Fishing operators affected by lower catch as anchovy and Pacific sardine move offshore to escape warm currents (5 degrees C above normal temperatures)
