Q

<p>How does<strong>soil erosion</strong>link to food insecurity?</p>

A

<p>Insufficient knowledge of technology to effectively farm can lead to over cultivation of land. This dries out the soil and exposes it to winds which erode the soil. Cattle may overgraze or too many trees may be remove which causes soils to bake</p>

</ul>

44
Q

<p>What is '<strong>urban farming</strong>'?</p>

A

<p>Using land in urban areas to farm e.g. roof tops, abandoned land</p>

A

<ul>
<li>Reduces over fishing</li>
<li>Cattle rearing often involves clearing land and is generally bad for the environment</li>
<li>Grass-fed meat provides natural manure for soil</li>
<li>Organic farming reduces waste, chemicals and energy used</li>
</ul>

47
Q

<p>How can<strong>seasonal food consumption</strong>create a more<strong>sustainable</strong>food supply?</p>

A

<p>Eating food that is in season reduces the amount of food that has to be imported. E.g. eating peaches outside of UK harvest means they have to be imported meaning more food miles</p>

48
Q

<p>What actions can be taken to<strong>reduce</strong>food waste?</p>

A

<ul>
<li>Sealed plastic bags to preserve food for longer</li>
<li>Educate public on 'best before' and 'use by' labels</li>
<li>Changing approach to food past its 'sell by'</li>
<li>More careful food storage</li>
</ul>

49
Q

<p>How can<strong>reducing food waste</strong>create a more sustainable food supply?</p>

A

<ul>
<li>Schemes such as 'Love Food Hate Waste' encourages and educates people on how to avoid food waste</li>
<li>Encouraging composting reduces landfill</li>
<li>Reducing waste will reduce demand</li>
</ul>

50
Q

<p>What is<strong>agroforestry</strong>?</p>

A

<p>Growing crops in amongst trees</p>

51
Q

<p>How is<strong>agroforestry</strong>appropriate for countries like Mali?</p>

A

<p>Desertification is likely as the land is dry therefore, planting crops under the shade of trees improves the nutrient and moisture content of the soil and prevents soil erosion</p>

52
Q

<p>How does<strong>agroforestry</strong>work in Mali?</p>

A

<p>Farmers plant crops amongst trees. The plants add nitrogen to the soil which means no fertilizers need to be added. Leaf litter adds further nutrients to soil. Trees protect crops from wind</p>

53
Q

<p>How is<strong>agroforestry</strong>in Mali an example of sustainable food supplies?</p>

A 
<ul>
	<li>Increases food production</li>
	<li>Maintains soil health</li>
	<li>Doesn't rely on overuse of chemicals</li>
	<li>Can be used continuously</li>
</ul>
54
Q

<p>What are the environmental impacts of the <b>mechanisation of farming</b>?</p>

A

<ul><li>Hedgerows have been removed to make space for larger fields. This has caused biodiversity to be lost</li>
<li>Soil erosion has increased as a result of heavy machinery being used more often</li>
<li>More and more chemicals are being used in the farming process. If these chemicals find their way into watercourses, biodiversity can be harmed</li></ul>

55
Q

<p>What are the environmental imapcts of <b>commercial fishing</b>?</p>

A

<ul><li>Species can become endangered if they are over-fished</li>
<li>Over-fishing also threatens other species in the same ecosystem</li>
<li>Seafloor habitats can be harmed by dredging</li>
<li>Overcrowded fish farms produce large amounts of waste, which can cause algal blooms if released into natural ecosystems. Algal blooms cause the oxygen content of the water to decrease, leading to the death of other organisms</li></ul>

56
Q

<p>What are the environmental imapcts of <b>deforestation</b>?</p>

A

<ul><li>Fewer trees mean the soil is held together less tightly, and so heavy rain can lead to soil erosion and potential landslides and flooding</li>
<li>Fewer trees mean more water hits the soil, leading to lower soil fertility because soil nutrients get washed away more regularly</li>
<li>Fewer trees mean less carbon dioxide is removed from the atmosphere by photosynthesis</li>
<li>Clearing forests by burning releases carbon dioxide</li></ul>

57
Q

<p>What are the environmentsal impacts of <b>mining</b>?</p>

A

<ul><li>Surface mining can cause landscape scarring</li><li>
</li><li>Methane and carbon dioxide are released into the atmosphere as a result of mining processes</li>
<li>Deforestation is necessary to make space for mines and access roads. This leads to loss of biodiversity and increased soil erosion</li></ul>
