production

what is it sustainable food production

is when food is produced

processed distributed and

disposed of in ways that contribute

to the community's environmental

economical and social

well-being

sustainable food production ensures

protection

of the diversity of both plants

and animals prevention

of the damage or waste of natural

resources which could contribute to

climate change provision

of social benefits such as

good quality food safe

and healthy products

sustainable food consumption

result of choices that consumers

make when purchasing products

in order not to affect the environment

and reduce waste

the way food is produced and

consumed has an effect on the

non-renewable resources

causes of unsustainable

food production and consumption

practices lead to defrustation

soil depletion and increased

energy demand major

causes of global warming global

environmental challenges

pollution and natural resources

depletion

let's look at the definition of a

renewable resource it is a resource

which can be used repeatedly

and replaced naturally

renewable energy almost never runs

out for example solar

energy wind energy

and hydro energy

definition of a non-renewable resource

it is a resource that cannot be quickly

and readily replaced by

natural means to keep up with

consumption examples

are fossil fuels

oil natural gas coal

and nuclear energy

what is sustainable food production

sustainable food production practices

can be adopted at individual level

agricultural level and

industrial levels

first let's look how it can be adopted

at individual or community

level people are

advised to cultivate vegetables

and food trees

this helps to reduce weed invasion

prevent land erosion and

promote a healthy biodiversity

use alternative transport

systems for example

working riding a bicycle and

using public transport while going for

groceries

at agricultural level sustainable

agriculture has an important role

to play in preserving

natural resources reducing greenhouse

gas

emissions reducing

biodiversity loss caring

for valued landscapes

example sustainable agriculture

is the cultivation of cassava

that is mango

all the cassava is primarily

grown for its roots all the parts of the

plant can

be used the wood as fuel

the leaves and peelings for animal feed

and even the stem for dietary salt

cassava plant grows well in

soil that does not require much

fertilizer

and the plant requires low rainfall

it shows good resistance to drought

diseases and pests

it is an environment friendly plant

that does not need treatment with

pesticides or

chemical fertilizers

as said before cassava is

primarily grown for its roots

all the parts of the plant can be used

as

wood as fuel leaves and peelings for

animal feed

stem for dietary salt

cassava can also be processed into flour

to make biscuits as well as tapioca

as we said in the mauritian language

sagu

from which different cassava-based

dishes

are prepared

at industrial level

food industries can develop more

sustainable food production practices

by reducing use of chemicals

examples artificial food additives

food sweeteners colors

etc can be reduced in food production

practices

we can also use recycled materials

for food packaging

sustainable food production practices

sustainable food production practices

take into consideration the social

economical and ecological

well-being some examples

of sustainable food production practices

are save water

apply the three hours that is reduce

reuse and recycle

support local food production

and grow your own food

how can we save water

without water neither people nor

plants nor animals could survive

will not grow in the fields and

eventually there will be no food

every living organisms consist of

about 80 percent of water

saving water helps to preserve

our environment saves

money and allows

constant safe food supplies

the three are practices

reduce reuse and recycle

what is reduce means

reduce waste example

compost food waste at home

the use of manure or compost

for plantation help to reduce use of

chemical

fertilizers which in turn help to reduce

water and land pollution

use cloth napkins instead

of paper napkins

example of compost food waste

at home

all jars and pots can be used to store

items in the kitchen

scrub fabrics can be used to make craft

items

recycle make new products

with materials that have been discarded

examples by products that can be

recycled

such as glass jars

dispose of your p t bottles

in special bins to be recycled

thus decreasing land pollution

what about supporting local food

production

local food production reduces

transportation of food products and thus

reduces air pollution produced by smoke

from vehicles

growing your own food

plant some of your own vegetables

and herbs pots

old boots boxes car tires

old furniture can be used to cultivate

herbs if you do not have a yard

you can use indoor pots

in today's video you have learned about

the definitions

of sustainable food production

sustainable food consumption causes

of unsustainable food production

and consumption i hope that you have

enjoyed this lesson

until the next thank you very much
