Q

How does food insecurity cause soil erosion?

A

Overcultivation and overgrazing along with lack of rainfall can lead to serious soil erosion, particularly in semi-arid regions. This causes soil infertility and limits food production

Q

How does economic development affect increasing food consumption

A

-as people become richer,they can afford to buy a greater quantity and variety of food,as a country develops,the demand for food(and its consumption)increases

-demand for convenience and highly processed foods increases with economic development as people have less time to prepare their own food

Q

What is irrigation and how does it increase food supply?

A

.used when there is insufficient water
.pipes in the ground which slowly drip water near to roots
.pivotal sprinklers
.uses water transfer to supply water
.helps places that dont have enough water to grow crops to be able to grow crops

Q

How do aeroponics and hydroponics help increase food supply and what are they?

A

.they are modern scientific techniques to grow crops without using soil. They are closely controlled by scientists meaning that plants can be grown throughout the year in artificially lit and heated greenhouses. Nutrients are applied directly to the roots.
.no need for soil to grow
.eliminates diseases that can be found in soil

Q

How does population growth affect increasing food consumption

A

-increases pressure on food production and supply due to increased demand
-majority of this population growth is in LICS and NEES where many people already suffer with food insecurity

Q

What is the new green revolution and how does it increase food supply?

A

.promoting nutrient cycling through crop rotation
.promoting modern sustainable and environmentally friendly farming practices
.helps people to understand sustainable ways of growing crops and increasing yield

Q

How does biotechnology help to increase food supply and what is it?

A

.a controversial scientific approach which is aimed at increasing yields by modifying products or processes
.eg. GM crops
.can increase yield
.uses fewer chemicals and emits less co2
.may not always directly increase food supply however they can increase farmers incomes which allows them to expand farms which can then increase food supply

19
Q

How does using appropriate technology increase food supply and what is it?

A

.low-tech solution that makes use of local people and local cheap or recycled materials
.commonly used in LIC’s
.often promoted by non-government organisations and charities
.it may involve simple water harvesting techniques, irrigation schemes or crop processing such as using bicycle power to de-husk coffee beens

20
Q

How does climate affect food supply

A

-droughts and flooding can cause severe food shortages
-climate change means factors may become severe and rainfall patterns may become irregular

21
Q

How does technology affect food supply

A

food supply and distribution in LICS can be due to the lack of:
-farm machinery(low yields)
-irrigation
-storage facilities
-transport infrastructure(distribution)
-processing facilities(to preserve food)

22
Q

How do pests and disease affect food supply

A

Many regions suffer from these but lack money to protect the crops and live stock
-locusts can devastate food crops
-cattle can be infected by airborne bacteria
-in poorer societies disease can reduce peoples capacity to be productive

23
Q

Affect of water stress on food supply

A

-lack of water security along with drought reduces food production
-HICS can afford water transfer schemes whereas LICS cannot
-by 2030 almost half the worlds population will be living in areas of high water stress
-climate change will increase water insecurity

24
Q

Affect of conflict on food supply

A

-war disrupts the distribution of food
-farmland may be mined
-people are forced to move away;land(homes and farms) are abandoned
-water supplies may be polluted
-food aid may be restricted in areas of military conflict

25
Q

Affect of poverty on food supply

A

-farmers in LICS can’t afford high quality:seeds,fertiliser or mechanisation that enables them to increase crop yield
-they may also suffer from under nutrition or malnourishment,reducing their ability to work

26
Q

Example of a local scheme in a LIC or NEE to increase sustainable supplies of food

A

Jamalpur,Bangladesh

27
Q

What is jamalpur

A

It’s an agricultural district in northern Bangladesh

28
Q

Example of a large-scale agricultural development

A

Almeria spain

29
Q

What are conditions like in almeria

A

Arid and dry

30
Q

Where in spain is almeria located

A

Southern spain

31
Q

How many hectares do greenhouses cover in almeria

A

31,000 hectares

32
Q

what is permaculture

A

(permanent agriculture) promotes farming that it promotes farming that is in harmony with the natural environment.

33
Q

What are grown in greenhouses in almeria?

A

A variety of fruits and vergetables that supply places like the uk with out of season vegetables and fruits

34
Q

organic farming

A

production of food without the use of chemicals

35
Q

What percent of Europe’s fruit and vegetables are produced in almeria?

A

Over 50%

36
Q

urban farming initiatives

A

often takes the form of community initiatives involving the conversionn of waste or derilict land into production farmland or vegetable gardens

37
Q

reduced waste and losses

A

lots of vegetables and fruit go off quickly so need to be consumed within 48 hours of production

38
Q

whagt fraction of food prodced is wasted

A

almost 1 third

39
Q

give examples of sustainable agriculture sustainable agriculture

A

rainwater harvesting, composting, crop rotation and woodland management

40
Q

Advantages of the greenhouses in almeria

A

.drip irrigation and hydroponic water recycling reduce water usage in this dry environment
.warm temperatures reduce energy costs
.jobs are created in the greenhouses and in packing and transportation
.new scientific food-related companies have been attracted to st up in the area, boosting the economy and creating jobs
.provides fresh fruit and vegetables throughout the year

41
Q

Disadvantages of greenhouses in almeria

A

.immigrant labour is low paid and living conditions are poor
.social clashes between immigrants and local people
.vast areas of land have been covered by plastic, affecting habitats and ecosystems
.plastic waste is a major issue,some of which is dumped into the sea
.use of pesticides is affecting human health
.some natural water sources are under stress

42
Q

Explain the process of a new practice rice-fish culture

A

-the charity practical action has been supporting a new practice Called rice-fish culture
-this is where small fish are introduced into the rice paddy fields,to provide a source of protein(for people eating the fish)to aerate the water and fertilise the soil(through their shit)
-rice yields have increased and family diets have improved
-surplus rice can be sold to provide extra income for farmers

43
Q

Why is rice-fish culture a good example of a sustainable approach to increasing food supplies

A

-doesn’t involve any artificial chemicals
-no expensive equipment or external expertise necessary
-doesn’t harm natural environment
