| Questão | Responda |
| List some social impacts of drought. (Hint: there are 5) | Dry soil - unstable house foundations Poor crop yield - food shortages Lack of water - dehydration Increased risk of diseases - cholera Few agricultural prospects - displacement / migration in search of food and income |
| List some economic impacts of drought. (Hint: there are 7) | Poor crop (yield) - higher prices Poor crop yield - low income for farmers Higher meat and dairy prices Fewer jobs Less corn (ethanol) - Higher fuel prices Drop in tourism Lower availability of goods (no exchange) |
| What is the economic impact of low water levels? | In inland docks and river systems the same boasts can't be used |
| List 4 environmental impacts of drought. | Desertification Malnourished plants - not attractive environment Fewer pollinating insects Dried out vegetation - more wildfires |
| Why does drought lead to desertification? | The dry soil causes root damage - the lack of root system causes cracks in the soil - when windy the top layer of soil is easily removed / swept away - future rain doesn't soak in as the surface is too hard |
| Why are there fewer pollinating insects as a result of drought? (Hint: there are 2 stages) | Natural plants (not crops) die first so there is not as much pollen for the insects THEN there are few crops as well AND more insecticides to save low yield |
| Name and locate a climatic hazard in an LEDC region. (Bonus: how many countries are in this region?) | 2012 (and 2010, 2005) Sahel region South of Sahara desert 12 countries including Niger, Chad, Mauritania, Mali, Burkina Faso |
| How many people were affected by the 2010 drought? | 10 milllion |
| What causes drought in the Sahel region? | Lack of rainfall |
| What factors worsen the impact of drought in the Sahel region? (Hint: there are 4) | Lack of Government intervention Mali conflict Tradition (many children) Change from traditional seed - maize Reliance on agriculture (80%) |
| Why did farmers recently chose to plant maize in favour of the traditional seed? Why is this bad? | Maize had higher value Traditional crop was drought resistant - maize is not |
| What are the effects on agriculture of drought in the Sahel region? (Hint: there are 4) | Crop production reduced by 26% Starvation of livestock (goats, sheep, cattle) - no meat or milk Price of grain doubled Grain stores running out - eating seeds |
| What are the social effects of drought in the Sahel region? (Hint: there are 5) | Food emergencies declared Migration Death 15% more malnourished 1/3 of children in Burkina Faso won't reach full growth potential |
| How did the process of desertification further complicate matters for the Sahel region? | When rains eventually came the ground was too hard to absorb them Flood waters blocked roads - difficult to deliver aid |
| According to the UN, how many people are at risk from severe food shortages? | 19 million |
| What short term solutions to drought were offered in the Sahel? (Hint: there are 5) | Red cross convoys - check for malnutrition Aid care packages e.g. food supplies Drought resistance seeds distributed Government aid Focus on vegetable gardens |
| What were the results of foreign aid charities' appeals? | They received 50% of $1.6 billion dollars requested |
| What was the problem with the Government's aid? | Only when wanting to win votes for rural areas |
| What problems do drought resistant seeds pose? (Hint: there are 4) | Ethical concerns about GM Reliance on other countries' technology Too expensive for average farmer Must be bought yearly (don't produce GM crop seeds) |
| What long term solutions to drought were considered and/or applied in the Sahel? (Hint: there are 2) | Family planning clinics (reduce number of children) Reduction of carbon emissions |
